Communication device 15 may operate in accordance with wireline protocols, such as Ethernet, digital subscriber line (DSL), asynchronous transfer mode (ATM), and/or the like.

[0059] Processor 1 1 may comprise means, such as circuitry, for implementing audio, video, communication, navigation, logic functions, and/or the like, as well as for implementing embodiments of the invention including, for example, one or more of the functions described herein. For example, processor 1 1 may comprise means, such as a digital signal processor device, a microprocessor device, various analog to digital converters, digital to analog converters, processing circuitry and other support circuits, for performing various functions including, for example, one or more of the functions described herein. The apparatus may perform control and signal processing functions of the electronic apparatus 10 among these devices according to their respective capabilities. The processor 1 1 thus may comprise the functionality to encode and interleave message and data prior to modulation and transmission.

Output Device 14 may comprise a visual output device, such as a display, a light, and/or the like. The electronic apparatus may comprise an input device 13. Input device 13 may comprise a light sensor, a proximity sensor, a microphone, a touch sensor, a force sensor, a button, a keypad, a motion sensor, a magnetic field sensor, a camera, and/or the like. A touch sensor and a display may be characterized as a touch display. In an embodiment comprising a touch display, the touch display may be configured to receive input from a single point of contact, multiple points of contact, and/or the like. In such an embodiment, the touch display and/or the processor may determine input based, at least in part, on position, motion, speed, contact area, and/or the like.

[0061] The electronic apparatus 10 may include any of a variety of touch displays including those that are configured to enable touch recognition by any of resistive, capacitive, infrared, strain gauge, surface wave, optical imaging, dispersive signal technology, acoustic pulse recognition or other techniques, and to then provide signals indicative of the location and other parameters associated with the touch. Additionally, the touch display may be configured to receive an indication of an input in the form of a touch event which may be defined as an actual physical contact between a selection object (e.g., a fmger, stylus, pen, pencil, or other pointing device) and the touch display. Alternatively, a touch event may be defined as bringing the selection object in proximity to the touch display, hovering over a displayed object or approaching an object within a predefined distance, even though physical contact is not made with the touch display. As such, a touch input may comprise any input that is detected by a touch display including touch events that involve actual physical contact and touch events that do not involve physical contact but that are otherwise detected by the touch display, such as a result of the proximity of the selection object to the touch display. A touch display may be capable of receiving information associated with force applied to the touch screen in relation to the touch input. For example, the touch screen may differentiate between a heavy press touch input and a light press touch input. In at least one example embodiment, a display may display two- dimensional information, three-dimensional information and/or the like.

[0062] In embodiments including a keypad, the keypad may comprise numeric (for example, 0-9) keys, symbol keys (for example, #, *), alphabetic keys, and/or the like for operating the electronic apparatus 10.

As such, the camera module may comprise hardware, such as a lens or other optical component(s), and/or software necessary for creating a digital image file from a captured image. Alternatively, the camera module may comprise only the hardware for viewing an image, while a memory device of the electronic apparatus 10 stores instructions for execution by the processor 1 1 in the form of software for creating a digital image file from a captured image. In at least one example embodiment, the camera module may further comprise a processing element such as a co-processor that assists the processor 1 1 in processing image data and an encoder and/or decoder for compressing and/or decompressing image data. The encoder and/or decoder may encode and/or decode according to a standard format, for example, a Joint Photographic Experts Group (JPEG) standard format.

[0064] FIGURES 2A-2D are diagrams illustrating apparatus communication according to at least one example embodiment. The examples of FIGURES 2 A-2D are merely examples of apparatus communication, and do not limit the scope of the claims. For example, proximity of the apparatuses may vary, type of communication may vary, communication path between apparatuses may vary, and/or the like.

[0065] As electronic apparatuses have become more prolific, there has been an increasing desire for users to utilize multiple electronic apparatuses collaboratively. For example, a user may have a plurality of electronic apparatuses. In such an example, the user may desire to share information from an electronic apparatus to another electronic apparatus, to transfer control of a resource from an electronic apparatus to another electronic apparatus, to have an electronic apparatus authorize another electronic apparatus to perform an action associated with the electronic apparatus, and/or the like. For example, the user may have content stored on an apparatus and desire to send a copy of the content to another apparatus. In such an example, the other apparatus may be the user's apparatus or a different user's apparatus. In another example, a user may have multiple communication apparatuses and desire to route communication from a communication apparatus to another communication apparatus. For example, the user may desire to forward calls from the apparatus to the other apparatus.

[0066] In some circumstances, a user may desire to have collaboration between apparatuses based on their proximity with each other. For example, it may be intuitive for a user to manage collaboration between apparatuses that are local to each other. A plurality of apparatuses may be proximate to each other based on location, availability of local

communication among the apparatuses, and/or the like. For example, if the apparatuses collaborate by way of near field communication, Bluetooth, infrared, local area network, wireless local area network, and/or the like, the apparatuses may be considered to be proximate with each other based, at least in part, on availability of such proximity-based communication with each other.

[0067] In at least one example embodiment, communication based, at least in part, on short range communication is referred to as proximity-based-communication. In at least one example embodiment, proximity-based communication relates to wireless communication that is associated with a short range, such as near field communication, Bluetooth, infrared, and/or the like. In such an example the exchange of information may be by way of the short range wireless communication between the apparatus and the other apparatus.

[0068] In some circumstances, proximity-based communication may relate to communication between apparatuses using a short range communication channel. In some circumstances, proximity-based communication may relate to communication between apparatuses using a communication channel that is not necessarily a short range communication channel. In such circumstances, the utilization of the communication channel may be predicated upon availability of a short range communication channel. For example, an apparatus may utilize a short range communication channel to obtain information associated with

communication across a different communication channel. For example, an apparatus may utilize short range communication with another apparatus to obtain address information for the other apparatus. In such an example, the apparatus may utilize the address information to communicate with the other apparatus by way of a different communication channel, such as a different short range communication channel, a communication channel that is not a short range communication channel, and/or the like. In at least one example embodiment, a communication channel relates to, at least partial, allocation of communication resources between an apparatus and another apparatus. For example, a communication channel may relate to a frequency designation, a channel designation, a sub-channel designation, a frame designation, and/or the like. An apparatus may have a plurality of communication channels. For example, an apparatus may have one or more communication channels with one or more other apparatuses, with one or more communication networks, and/or the like. For purposes of clarity, a communication channel may be referred to in terms of an apparatus involved in the communication channel. For example, a communication channel associated with an apparatus may be referred to as an apparatus communication channel, a communication channel associated with a separate apparatus may be referred to as a separate apparatus communication channel, a communication channel associated with a communication network may be referred to as a communication network communication channel, and/or the like.

[0069] In at least one example embodiment, an apparatus may be involved in establishment of a communication channel. For example, there may be various actions that an apparatus may take for a communication channel to become existent between the apparatus and another apparatus, a communication network, and/or the like. After a communication channel is established, the communication channel may be utilized for communication. In at least one example embodiment, an apparatus may be involved in termination of a communication channel. For example, there may be various actions that an apparatus may take for a communication channel to become non-existent between the apparatus and another apparatus, a communication network, and/or the like. After a communication channel is terminated, the communication channel may be unavailable for communication. In at least one example embodiment, existence of a communication channel between an apparatus and another apparatus is indicative of the apparatus being in communication with the other apparatus.

[0070] In at least one example embodiment, an apparatus receives an indication of availability of proximity-based communication with a separate apparatus. The indication of availability may relate to information indicating that the other apparatus is within range of a short range communication, an indication that the other apparatus is present on a short range communication network, and/or the like. In at least one example embodiment, the apparatus determines that the other apparatus is unavailable for proximity -based communication by way of absence of information indicative of availability of the proximity-based communication.

[0071] In the example of FIGURE 2A, apparatus 201 and apparatus 202 may collaborate locally. In some circumstances, apparatus 201 and apparatus 202 may communicate directly with each other, such as by way of proximity-based communication, by way of communication channel 21 1. In the example of FIGURE 2 A, the proximity-based

communication range of apparatus 201 is indicated by region 215 and the proximity -based communication range of apparatus 202 is indicated by region 216. In some circumstances, apparatus 201 may communicate with apparatus 202 by way of communication network 203. For example, communication network 203 may be an intermediary apparatus such that apparatus 201 and apparatus 202 may communicate with each other by way of communication channels 212 and 213, may be a group of apparatuses in communication with each other such that apparatus 201 and apparatus 202 may communicate with each other by way of communication channels 212 and 213, and/or the like. In some circumstances, apparatus 201 may obtain information from apparatus 202, by way of communication channel 21 1 , that allows apparatus 201 to communicate with apparatus 202 by way of communication network 203.

[0072] In at least one example embodiment, a communication network relates to one or more apparatuses that provide for communication between an apparatus and another apparatus. For example, the communication network may comprise a plurality of communication apparatuses. A communication apparatus may be any apparatus associated with facilitation of communication in a communication network. For example, a communication apparatus may relate to an access point for the communication network, such as a wireless access point, a cellular base station, a Bluetooth access point, and/or the like. In another example, a

communication network apparatus may relate to an apparatus utilized for communication within the communication network, such as a hub, a router, a switch, and/or the like. In at least one example embodiment, an apparatus may be in communication with a communication network by way of a communication channel with a communication apparatus of the communication network. In at least one example embodiment, an apparatus that does not have a communication channel with a communication apparatus may not be in communication with the communication apparatus. In some circumstances, an apparatus and another apparatus may communicate by way of a communication network by way of the same communication apparatus. For example, an apparatus may communicate with another apparatus, by way of a cellular network, where the apparatus and the other apparatus are in communication with the same base station of the cellular network. In such an example, the apparatus and the other apparatus may be within a region that is covered by the base station.

[0073] In at least one example embodiment, an apparatus may utilize a communication network for a call. In at least one example embodiment, a call relates to user communication session between an apparatus and another apparatus, such as a voice call, a video call, and/or the like. In at least one example embodiment, a communication network utilizes a call endpoint identifier in association with a call for an apparatus. In at least one example embodiment, the call endpoint identifier relates to an identifier for designating communication information to at least one apparatus in a communication network. For example, the call endpoint identifier may relate to a phone number, a uniform resource locator (URL), and/or the like. In at least one example embodiment, the communication network utilizes an existing communication channel to allow the apparatus to enter a call. In at least one example embodiment, an apparatus enters a call is by way of the communication channel. An apparatus may enter a call by way of establishing a call, for example an origination call, may enter a call by way of receiving a call, for example a termination call, and/or the like. The communication network may route call information to one or more apparatuses based on the call endpoint identifier. For example, a cellular network may determine one or more apparatus identifier that is associated with a call endpoint identifier, such as an international mobile equipment identity (IMEI) that is associated with a phone number, and utilize the apparatus identifier to provide call information to the apparatus. In at least one example embodiment, a call endpoint identifier is associated with an apparatus by way of the apparatus being designated to receive call information based, at least in part, on the call endpoint identifier.

[0074] In at least one example embodiment, an apparatus may have more than one call endpoint identifier. For example, the apparatus may be associated with multiple phone numbers, be associated with multiple subscriber accounts, be associated with multiple types of calls, be associated with multiple communication networks, and/or the like. For example, an apparatus may be in communication with a cellular network, a wireless local area network, a Bluetooth network, and/or the like. In such an example, there may be a call endpoint identifier associated with a communication network and a different call endpoint identifier associated with a different communication network. In this manner, a communication channel that the apparatus utilizes in communication with such a communication network may be considered to be associated with the call endpoint identifier. For example, the apparatus may have a communication channel that is associated with a call endpoint identifier and a different communication channel that is associated with a different call endpoint identifier. In this manner, a communication channel may be associated with entrance to a call by way of the associated call endpoint identifier. For example, an apparatus may utilize an apparatus communication channel for entrance to a call by way of a call endpoint identifier, and a different apparatus may utilize a different apparatus communication channel for entrance to a call by way of a call endpoint identifier. In at least one example embodiment, a call relates to a cellular call, and an apparatus communication channel relates to an apparatus cellular communication channel.

[0075] In some circumstances, an apparatus may periodically examine a

communication channel to determine if the communication network is attempting to establish a call with the apparatus. For example, there may be a designated channel, time interval, frame, and/or the like, in which the communication network will provide call information to the apparatus, if there is any call information to be provided to the apparatus. For example, a cellular network may designate a paging frame for the apparatus. In this manner, the apparatus may save power by reducing power associated with, at least part of, the apparatus associated with the communication channel. For example, the apparatus may remain registered to a communication channel, but may intermittently reacquire the communication channel to determine presence of call information. In this manner, the apparatus may be spared power consumption associated with receiving information from the communication channel that is not likely to be applicable to the apparatus. In some circumstances, the amount of time which the apparatus may receive information by way of a communication channel may be changed. For example, the interval between possible communications regarding a call may be changed. In such an example, the apparatus may save more power in association with a greater interval between evaluations that in association with a lesser interval between evaluations. For example, the reduction of the amount of time may relate to an increased communication frame interval associated with the separate apparatus communication channel. In at least one example embodiment, the communication frame interval relates to a paging frame.

[0076] In some circumstances, an apparatus may save power by terminating a communication channel associated with a call endpoint identifier. For example, the apparatus may determine that it is, at least temporarily, undesirable to receive call information associated with the call endpoint identifier. In such an example, the apparatus may still utilize other communication channels of the same communication network or a different communication network, as desired.

[0077] In at least one example embodiment, the apparatus and/or the communication network may end the call. In such an example, there may be communication between the apparatus associated the ending of the call. For example, the apparatus may send information to the communication network to cause the ending of the call, the communication network may send information to the apparatus to facilitate ending of the call, and/or the like.

[0078] In some circumstances, a user may desire to utilize multiple apparatuses as companion apparatuses. In at least one example embodiment, companion apparatuses relate to apparatuses that collaborate with each other. For example, a companion apparatus may automatically communicate with another companion apparatus for purposes such as

synchronizing data, exchanging status information, and/or the like. In at least one example embodiment, at least two companion apparatuses are associated with the same call endpoint identifier. For example, a communication network may send call information to both apparatuses in relation to the same call endpoint identifier. Without limiting the scope of the claims in any way, at least one technical effect associated with at least two companion apparatuses being associated with the same call endpoint identifier may be to allow the user to enter calls on any one of the apparatuses that the user elects. For example, the user may prefer an apparatus in some circumstances and prefer a different apparatus in other circumstances. For example, the user may desire to utilize an apparatus at the office, desire to utilize a different apparatus in the car, and/or the like. In this manner, the user may freely use such apparatuses without necessarily performing additional forwarding operations.

[0079] In some circumstances, an apparatus associated with a call endpoint identifier may be capable of determining that another apparatus is associated with the same call endpoint identifier. For example, the apparatus may receive information indicative of one or more other apparatuses that are associated with the same call endpoint identifier from the other apparatus, from a communication network associated with the call endpoint identifier, and/or the like. In another example, the apparatus may store information indicative of one or more other apparatuses that are associated with the same call endpoint identifier.

[0080] Similarly, the apparatus may determine that another apparatus utilizes other types of communication channels that utilize common resources. For example, the apparatus may communicate with an email server by way of a wireless network. In such an example, the apparatus may determine that the other apparatus communicates with the email server by way of the wireless network, a different wireless network, and/or the like. [0081] As apparatuses have become more complex, and have become more highly integrated into the lives of their users, power savings has become increasingly desirable in apparatuses. In some circumstances, it may be desirable to limit power consumption associated with utilization of a communication channel associated with a call endpoint identifier.

[0082] As previously stated, in situations where multiple apparatuses use the same call endpoint identifier, the user may desire to use different apparatuses in different circumstances. For example, the user may prefer to take an apparatus with him when he leaves his home and to leave another apparatus at home. In such circumstances, the user may be unable to utilize the other apparatus for, at least, the reason that the user does not possess the apparatus, in such circumstances, it may be desirable to save power of the other apparatus by way of controlling the power consumption from with the communication channel associated with the shared call endpoint identifier. For example, the other apparatus may reduce the amount of time associated with evaluating the communication channel for call information, may terminate the

communication channel, and/or the like.

[0083] In some circumstances, it may be desirable for an apparatus to base

configuration of the communication channel on proximity of the apparatus to a separate apparatus that is associated with the same call endpoint identifier. For example, the apparatus may infer that the apparatus not being proximate to each other is indicative of the user desiring to prefer entering a call on an apparatus instead of another apparatus. In some circumstances, it may be desirable to determine which, of the non-proximate apparatuses the user has possession of. For example, even though the apparatus may determine that the apparatus are not proximate to each other, it may be desirable to reduce power consumption associated with the apparatus that is not proximate to the user, and to avoid such reduced power consumption associated with the apparatus that is proximate to the user. In at least one example embodiment, the apparatus determines that the user is proximate to the apparatus by way of the user entering a call on the apparatus. For example, the user may initiate a call, may answer a received call, and/or the like.

[0084] For example, the user may have a first apparatus and a second apparatus that are associated with the same call endpoint identifier. The user may leave the first apparatus at his office and take the second apparatus with him. It may be desirable for the first apparatus to save power related to a communication channel associated with the call endpoint identifier. In such an example, the first apparatus and/or the second apparatus may determine that the apparatuses are not proximate to each other. In at least one example embodiment, the apparatuses may determine which apparatus the user has with him by way of the second apparatus entering a call. In this manner, the first apparatus and/or the second apparatus may infer that user does not desire to enter calls using the first apparatus. Such inference may be based, at least in part, on the first and second apparatus not being proximate to each other and the second apparatus entering a call. In this manner, the inference that the user does not desire to enter calls using the first apparatus may indicate an opportunity to save power related to a communication channel associated with the call endpoint identifier.

[0085] In at least one example embodiment, an apparatus may determine that the apparatus is not proximate to another apparatus. For example, the apparatus may determine that another apparatus is not proximate to the apparatus by determining that a position of the apparatus is beyond a threshold distance from a position of the other apparatus, similar as described regarding FIGURE 7. In another example, the apparatus may determine that another apparatus is not proximate to the apparatus based, at least in part, on a determination that the apparatus and the other apparatus are not in communication with the same communication apparatus of the communication network associated with the call endpoint identifier, similar as described regarding FIGURE 8. In another example, the apparatus may determine that another apparatus is not proximate to the apparatus based, at least in part, on determination that the other apparatus is unavailable for proximity-based communication, similar as described regarding FIGURE 9.

[0086] In yet another example, the apparatus may determine that another apparatus is not proximate to the apparatus based, at least in part, on determination that the other apparatus is unavailable for communication on a local area network, such as a wireless local area network, with which the apparatus is in communication. For example, the apparatus may infer that the lack of availability of the other apparatus for communication on the local area network is due to the other apparatus being outside of the coverage area of the local area network. The apparatus may further infer that being outside of the coverage area of the local area network implies that the apparatus is not proximate to the other apparatus.

[0087] In the example of FIGURE 2 A apparatus 201 may determine that apparatus 202 is proximate based, at least in part, on availability of proximity -based communication 21 1 , by way of communicating with the same communication apparatus of communication network 203 , by way of comparing position information of apparatus 201 and position information of apparatus 202, and/or the like.

[0088] In the example of FIGURE 2B, apparatus 221 and apparatus 222 are in communication with communication network 223 and communication network 224. Apparatus 221 is in communication with communication network 224 by way of communication channel 232, and in communication with communication network 223 by way of communication channel 234. Apparatus 222 is in communication with communication network 224 by way of communication channel 233, and in communication with communication network 223 by way of communication channel 235.

[0089] Communication network 223 may be a different communication network than communication network 224. For example, communication network 223 may be a local area network and communication network 224 may be a cellular network. In another example, communication network 223 may be a cellular network and communication network 224 may be a different cellular network. In some circumstances, communication network 223 may be associated with a call endpoint identifier, and communication network 224 may be unassociated with the call endpoint identifier. In such an example, apparatus 221 may determine to save power associated with communication channel 234 based, at least in part, on determination that apparatus 221 is not proximate to apparatus 222 and entry of a call by apparatus 222. In such an example, apparatus 221 may save power associated with communication channel 234 without regard for power savings associated with communication channel 232, if any.

[0090] In the example of FIGURE 2C, apparatus 251 and apparatus 252 may communicate with each other by way of communication network 253. Apparatus 251 may be in communication with communication network 253 by way of communication channel 262.

Apparatus 252 may be in communication with communication network 253 by way of communication channel 263. In the example of FIGURE 2C, the proximity-based

communication range of apparatus 251 is indicated by region 265 and the proximity-based communication range of apparatus 252 is indicated by region 266. It can be seen that apparatus 252 is unavailable for proximity -based communication with apparatus 251. In some

circumstances, apparatus 251 may communicate with apparatus 252 by way of communication network 253. In the example of FIGURE 2C, apparatus 251 may determine that apparatus 252 is not proximate to apparatus 251 based, at least in part on unavailability of proximity -based communication with apparatus 252.

[0091] In the example of FIGURE 2D, apparatus 271 and apparatus 272 are in communication with communication network 273. Apparatus 271 is in communication with communication network 274 by way of communication channel 282, and in communication with communication network 274 by way of communication channel 284. Apparatus 272 is in communication with communication network 273 by way of communication channel 283, and in communication with communication network 275 by way of communication channel 285.

[0092] In some circumstances, communication network 273 may be associated with a call endpoint identifier, and communication networks 274 and 275 may be unassociated with the call endpoint identifier. In such an example, apparatus 271 may determine to save power associated with communication channel 282 based, at least in part, on determination that apparatus 271 is not proximate to apparatus 272 and entry of a call by apparatus 272. In such an example, apparatus 271 may save power associated with communication channel 282 without regard for power savings associated with communication channel 284, if any.

[0093] FIGURE 3 is a flow diagram illustrating action associated with communication channel power reduction according to at least one example embodiment. The example of FIGURE 3 is merely an example of action associated with communication channel power reduction, and does not limit the scope of the claims. For example, interactions may vary, order of interactions may vary, number of apparatuses may vary, and/or the like.

[0094] In at least one example embodiment, an apparatus may cause communication channel power reduction of a separate apparatus by way of sending information to the separate apparatus. For example, the apparatus may send a communication channel power reduction directive to the separate apparatus. In at least one example embodiment, the communication channel power reduction directive relates to a communication associated with an instruction indicative of a reduction in power. For example, the communication channel power reduction directive may relate to a communication channel termination directive. In at least one example embodiment, a communication channel termination directive relates to a communication associated with an instruction indicative of a channel termination. In another example, the communication channel power reduction directive may relate to a call entry notification. In at least one example embodiment, the call entry notification relates to a communication that signifies the entry of the call. For example, the apparatus may cause the separate apparatus to reduce power associated with the communication channel by way of notifying the separate apparatus that the apparatus has entered a call associated with the shared call endpoint identifier. In this manner, the separate apparatus may determine that power reduction of the communication channel associated with the call endpoint identifier is desirable.

[0095] The example of FIGURE 3 relates to interaction among apparatus 301 , communication network 303, and apparatus 302. At block 310 apparatus 301 enters a call associated with a call endpoint identifier with communication network 303. The entry, the call, and the call endpoint identifier may be similar as described regarding FIGURES 2A-2D.

[0096] In the example of FIGURE 3, apparatus 301 and apparatus 302 are associated with the same call endpoint identifier. At block 312, apparatus 301 determines that apparatus 302 is associated with the call endpoint identifier. The determination may be similar as described regarding FIGURES 2A-2D.

[0097] At block 314, apparatus 301 determines that apparatus 302 is not proximate to apparatus 301. The determination and the proximity may be similar as described regarding FIGURES 2A-2D, FIGURE 7, FIGURE 8, FIGURE 9, and/or the like.

[0098] At interaction 316, apparatus 301 sends a communication channel power reduction directive to apparatus 301. The sending may be similar as described regarding FIGURES 2A-2D. Apparatus 301 may send the communication channel power directive based, at least in part, on the determination that apparatus 302 is not proximate to apparatus 301.

Apparatus 301 may send the communication channel power directive based, at least in part, on the entry of the call. In at least one example embodiment, the communication channel power reduction directive relates to an apparatus 302 communication channel that is associated with the call endpoint identifier, such as a communication channel between apparatus 302 and communication network 303.

[0099] At block 318, apparatus 302 causes power reduction of the communication channel between apparatus 302 and communication network 303. The power reduction may be similar as described regarding FIGURES 2A-2D.

[00100] Even though the example of FIGURE 3 relates to a call, and the communication network is associated with the call endpoint identifier, similar teachings may be applicable to other technologies as well. For example, utilization of a wireless network by the apparatus may cause power reduction of a wireless networking channel of the other apparatus. Likewise, entry of a call may cause power reduction of a communication channel other than the communication channel of the communication network associated with the call endpoint identifier. For example, entry of the call may cause the apparatus to send s communication channel power reduction directive to the apparatus that causes reduction of power for other communication channels, such as a wireless networking communication channel, a Bluetooth communication channel, and/or the like. In this manner, the apparatus may determine that utilization of the communication channel is indicative of a user action associated with the apparatus. The apparatus may base, at least in part, a communication channel power reduction directive on such a determination that utilization of the communication channel is indicative of a user action associated with the apparatus. For example, the apparatus may determine that a user sending an email is indicative of a user action sufficient to cause the apparatus to send a communication channel power reduction directive to the other apparatus. In such an example, the communication channel power reduction directive may cause the other apparatus to reduce power associated with the communication channel associated with email, the communication channel associated with the call endpoint identifier, and/or the like. In another example, the apparatus may determine that utilization of a wireless network for downloading information is indicative of a user action sufficient to cause the apparatus to send a communication channel power reduction directive to the other apparatus. In such an example, the communication channel power reduction directive may cause the other apparatus to reduce power associated with the communication channel associated with the download, the communication channel associated with the call endpoint identifier, and/or the like. FIGURE 4 is a flow diagram illustrating action associated with communication channel power reduction according to at least one example embodiment. In at least one example embodiment, there is a set of operations that corresponds to the activities of FIGURE 4. An apparatus, for example electronic apparatus 10 of FIGURE 1, or a portion thereof, may utilize the set of operations. The apparatus may comprise means, including, for example processor 11 of FIGURE 1 , for performance of such operations. In an example embodiment, an apparatus, for example electronic apparatus 10 of FIGURE 1, is transformed by having memory, for example memory 12 of FIGURE 1 , comprising computer code configured to, working with a processor, for example processor 11 of FIGURE 1 , cause the apparatus to perform set of operations of FIGURE 4. [00101] At block 402, the apparatus enters a call associated with a call endpoint identifier. In at least one example embodiment, the call endpoint identifier is associated with the apparatus. The entry, the call, the call endpoint identifier and the associations may be similar as described regarding FIGURES 2A-2D.

[00102] At block 404, the apparatus determines that a separate apparatus is associated with the call endpoint identifier. The determination may be similar as described regarding FIGURES 2A-2D.

[00103] At block 406, the apparatus determines that the separate apparatus is not proximate to the apparatus. The determination and the proximity may be similar as described regarding FIGURES 2A-2D, FIGURE 7, FIGURE 8, FIGURE 9, and/or the like.

[00104] At block 408, the apparatus sends a communication channel power reduction directive to the separate apparatus. The communication channel power reduction directive may be based, at least in part, on the determination that the separate apparatus is not proximate to the apparatus. The communication channel power reduction directive may be based, at least in part, on the entry of the call. In at least one example embodiment, the communication channel power reduction directive relates to a separate apparatus communication channel that is associated with the call endpoint identifier. The sending, the communication channel power directive, the separate apparatus communication channel, and the associations may be similar as described regarding FIGURES 2A-2D, FIGURE 3, and/or the like.

[00105] FIGURE 5 is a flow diagram illustrating action associated with communication channel power reduction according to at least one example embodiment. The example of FIGURE 5 is merely an example of action associated with communication channel power reduction, and does not limit the scope of the claims. For example, interactions may vary, order of interactions may vary, number of apparatuses may vary, and/or the like.

[00106] In at least one example embodiment, sending the communication channel power reduction directive to a separate apparatus comprises sending the communication channel power reduction directive to the separate apparatus by way of a communication network that is associated with the separate apparatus communication channel. For example, apparatus 501 may send a communication channel power reduction directive to apparatus 502 by way of communication network 503.

At interaction 518, communication network 503 sends the communication channel power reduction directive to apparatus 502.

[00109] At block 520, apparatus 502 causes power reduction of the communication channel between apparatus 502 and communication network 503. The power reduction may be similar as described regarding FIGURES 2A-2D.

[00110] FIGURE 6 is a flow diagram illustrating action associated with communication channel power reduction according to at least one example embodiment.

For example, interactions may vary, order of interactions may vary, number of apparatuses may vary, and/or the like.

[00111] In at least one example embodiment, sending the communication channel power reduction directive to the separate apparatus comprises sending the communication channel power reduction directive to the separate apparatus by way of a communication network that is unassociated with the separate apparatus communication channel. In the example of FIGURE 6, communication network 603 is associated with a call endpoint identifier, and communication network 604 is unassociated with the call endpoint identifier. Without limiting the scope of the claims in any way, at least one technical effect associated with sending the communication channel power reduction directive to the separate apparatus by way of a communication network that is unassociated with the separate apparatus communication channel may be to allow for communication between the apparatus and the separate apparatus by way of a channel that is not necessarily subject to the communication channel power reduction directive.

[00117] At block 702, the apparatus determines the position of the apparatus. In at least one example embodiment, determination of the position of the apparatus comprises receiving information indicative of the position of the apparatus. The information indicative of position of the apparatus may relate to geographic location information. In this manner, the position may relate to a geographic position.

In an example embodiment, an apparatus, for example electronic apparatus 10 of FIGURE 1 , is transformed by having memory, for example memory 12 of FIGURE 1 , comprising computer code configured to, working with a processor, for example processor 1 1 of FIGURE 1 , cause the apparatus to perform set of operations of FIGURE 10. [00134] In some circumstances a user may intermittently move in a manner that causes an apparatus to be non-proximate to a separate apparatus. For example, a user may move around an office building in a manner that causes the apparatuses to be non-proximate for a short period of time. In some circumstances, it may be desirable to avoid causing communication channel power reduction based on a short duration separation of the apparatuses. In at least one example embodiment, the apparatus determines that a threshold separation time has elapsed with the apparatus being non-proximate to the separate apparatus such that sending a communication channel power reduction directive is based, at least in part, on the determination that the threshold separation time has elapsed. In at least one example embodiment, the apparatus predicates sending a communication channel power reduction directive on a determination that the apparatus and the separate apparatus have been non-proximate for at least a threshold separation time. In at least one example embodiment, a threshold separation time relates to a predetermined duration beyond which is associated with desirability of sending a communication channel power reduction directive. In at least one example embodiment, the apparatus may further determine that the apparatus remains non-proximate to the separate apparatus, such that sending the communication channel power reduction directive is based, at least in part, on the determination the apparatus remains non-proximate to the separate apparatus. For example, the apparatus may avoid sending the communication channel power reduction directive if the separate apparatus becomes proximate to the apparatus prior to sending the communication channel power reduction directive.

[00135] At block 1002, the apparatus enters a call associated with a call endpoint identifier similar as described regarding block 402 of FIGURE 4. At block 1004, the apparatus determines that a separate apparatus is associated with the call endpoint identifier, similarly as described regarding block 404 of FIGURE 4. At block 1006, the apparatus determines that the separate apparatus is not proximate to the apparatus, similarly as described regarding block 406 of FIGURE 4.

[00136] At block 1008, the apparatus determines whether a threshold separation time has elapsed. If the apparatus determines that a threshold separation time has elapsed, flow proceeds to block 1010. If the apparatus determines that a threshold separation time has not elapsed, flow may return to block 1008. [00137] At block 1010, the apparatus determines whether the separate apparatus is proximate to the apparatus. The determination and the proximity may be similar as described regarding FIGURES 2A-2D, FIGURE 7, FIGURE 8, FIGURE 9, and/or the like. If the apparatus determines that the separate apparatus is proximate to the apparatus, flow returns to block 1006. If the apparatus determines that the separate apparatus is not proximate to the apparatus, flow proceeds to block 1012. In this manner, the apparatus may determine that the apparatus remains non-proximate to the separate apparatus prior to proceeding to block 1012.

[00138] At block 1012, the apparatus sends a communication channel power reduction directive to the separate apparatus, similarly as described regarding block 408 of FIGURE 4.

[00139] FIGURE 1 1 is a flow diagram illustrating action associated with communication channel power reduction according to at least one example embodiment. In at least one example embodiment, there is a set of operations that corresponds to the activities of FIGURE 1 1. An apparatus, for example electronic apparatus 10 of FIGURE 1 , or a portion thereof, may utilize the set of operations. The apparatus may comprise means, including, for example processor 1 1 of FIGURE 1 , for performance of such operations. In an example embodiment, an apparatus, for example electronic apparatus 10 of FIGURE 1 , is transformed by having memory, for example memory 12 of FIGURE 1 , comprising computer code configured to, working with a processor, for example processor 1 1 of FIGURE 1 , cause the apparatus to perform set of operations of FIGURE 1 1.

[00140] In some circumstances, it may be desirable to cause the separate apparatus to cancel the communication channel power reduction. For example, it may be desirable for the separate apparatus to return the communication channel to its previous state, to re-establish the communication channel, and/or the like. In some circumstances, it may be desirable to cancel the communication channel power reduction based, at least in part, on the apparatus and the separate apparatus becoming proximate to each other. For example, the user may leave the separate apparatus at home and take the apparatus with him. In such an example, the separate apparatus may enter communication channel power reduction. Upon returning home with the apparatus, the user may desire to be able to utilize the separate apparatus for a call. In this manner, the apparatus becoming proximate to the separate apparatus again may be indicative of desirability of entering a call by the separate apparatus. [00141] In at least one example embodiment, the apparatus sends, to the separate apparatus, a communication channel power reduction cancelation directive based, at least in part, on the determination that the apparatus has become proximate to the separate apparatus. In at least one example embodiment, the communication channel power reduction cancelation directive relates to a communication associated with an instruction indicative of a canceling a reduction in power. For example, the communication channel power reduction directive may relate to a communication channel restoration directive. In at least one example embodiment, a communication channel restoration directive relates to a communication associated with an instruction indicative of establishing a communication channel, restoring the communication channel to its previous state, and/or the like.

[00142] Even though the example of FIGURE 1 1 relates to the apparatus causing the separate apparatus to cancel the separate apparatus communication channel power reduction, the separate apparatus may cancel the separate apparatus communication channel power reduction without a directive from the apparatus. For example, the separate apparatus may determine that the apparatus has become proximate to the separate apparatus. In such an example, the separate apparatus may restore the separate apparatus communication channel based, at least in part, on the determination that the apparatus has become proximate to the separate apparatus.

[00143] In at least one example embodiment, sending a communication channel power reduction cancelation directive comprises sending a communication channel power reduction cancelation directive by way of a communication network that is associated with the separate apparatus communication channel. For example, the apparatus may send the communication channel power reduction cancelation directive to the separate apparatus by way of the communication network associated with the call endpoint identifier.

[00144] However, in some circumstances, the separate apparatus may no longer be in communication with the communication network associated with the call endpoint identifier.

For example, the communication channel power reduction of the separate apparatus may relate to termination of the communication channel. In such circumstances, the separate apparatus may be unable to receive communication by way of the communication network associated with the call endpoint identifier. In at least one example embodiment, sending the communication channel power reduction cancelation directive to the separate apparatus comprises sending the communication channel power reduction cancelation directive to the separate apparatus by way of a communication network that is unassociated with the separate apparatus communication channel.

[00145] At block 1 102, the apparatus enters a call associated with a call endpoint identifier similar as described regarding block 402 of FIGURE 4. At block 1 104, the apparatus determines that a separate apparatus is associated with the call endpoint identifier, similarly as described regarding block 404 of FIGURE 4. At block 1 106, the apparatus determines that the separate apparatus is not proximate to the apparatus, similarly as described regarding block 406 of FIGURE 4. At block 1 108, the apparatus sends a communication channel power reduction directive to the separate apparatus, similarly as described regarding block 408 of FIGURE 4.

[00146] At block 1 1 10, the apparatus determines that the apparatus has become proximate to the separate apparatus. The determination and the proximity may be similar as described regarding FIGURES 2A-2D, FIGURE 7, FIGURE 8, FIGURE 9, and/or the like.

[00147] At block 1 1 12, the apparatus sends, to the separate apparatus, a communication channel power reduction cancelation directive. In this manner the apparatus may send the communication channel power reduction cancelation directive based, at least in part, on the determination that the apparatus has become proximate to the separate apparatus.

[00148] FIGURE 12 is a flow diagram illustrating action associated with communication channel power reduction according to at least one example embodiment. In at least one example embodiment, there is a set of operations that corresponds to the activities of FIGURE 12. An apparatus, for example electronic apparatus 10 of FIGURE 1 , or a portion thereof, may utilize the set of operations. The apparatus may comprise means, including, for example processor 1 1 of FIGURE 1 , for performance of such operations. In an example embodiment, an apparatus, for example electronic apparatus 10 of FIGURE 1 , is transformed by having memory, for example memory 12 of FIGURE 1 , comprising computer code configured to, working with a processor, for example processor 1 1 of FIGURE 1 , cause the apparatus to perform set of operations of FIGURE 12.

[00149] In some circumstances, it may be desirable to cause the separate apparatus to cancel the communication channel power reduction. For example, it may be desirable for the separate apparatus to return the communication channel to its previous state, to re-establish the communication channel, and/or the like. In some circumstances, it may be desirable to cancel the communication channel power reduction based, at least in part, on the apparatus ending a call. For example, the user may desire for the separate apparatus be receive call information at times when the apparatus is not in a call. In such an example, the separate apparatus may enter communication channel power reduction when the apparatus is in a call. Upon ending the call with the apparatus, the user may desire the separate apparatus to receive call information. In this manner, the apparatus ending the call may be indicative of desirability of entering a call by the separate apparatus.

[00150] In at least one example embodiment, the apparatus sends, to the separate apparatus, a communication channel power reduction cancelation directive based, at least in part, on the end of a call. The communication channel power reduction cancelation directive may be similar as described regarding FIGURE 1 1.

[00151] In at least one example embodiment, sending a communication channel power reduction cancelation directive comprises sending a communication channel power reduction cancelation directive by way of a communication network that is associated with the separate apparatus communication channel. For example, the apparatus may send the communication channel power reduction cancelation directive to the separate apparatus by way of the communication network associated with the call endpoint identifier.

[00152] However, in some circumstances, the separate apparatus may no longer be in communication with the communication network associated with the call endpoint identifier. For example, the communication channel power reduction of the separate apparatus may relate to termination of the communication channel. In such circumstances, the separate apparatus may be unable to receive communication by way of the communication network associated with the call endpoint identifier. In at least one example embodiment, sending the communication channel power reduction cancelation directive to the separate apparatus comprises sending the communication channel power reduction cancelation directive to the separate apparatus by way of a communication network that is unassociated with the separate apparatus communication channel.

[00153] At block 1202, the apparatus enters a call associated with a call endpoint identifier similar as described regarding block 402 of FIGURE 4. At block 1204, the apparatus determines that a separate apparatus is associated with the call endpoint identifier, similarly as described regarding block 404 of FIGURE 4. At block 1206, the apparatus determines that the separate apparatus is not proximate to the apparatus, similarly as described regarding block 406 of FIGURE 4. At block 1208, the apparatus sends a communication channel power reduction directive to the separate apparatus, similarly as described regarding block 408 of FIGURE 4.

[00154] At block 1210, the apparatus ends the call. The ending may be similar as described regarding FIGURES 2A-2D.

[00155] At block 1212, the apparatus sends, to the separate apparatus, a communication channel power reduction cancelation directive. In this manner the apparatus may send the communication channel power reduction cancelation directive based, at least in part, on the end of the call.
