TW201408098A - Method and device for managing warning notifications - Google Patents

Abstract

In some implementations, a method for managing warning notifications includes identifying a trigger event. A status of a setting in User Equipment (UE) to indicate at least one of enablement or disablement of warning notifications in a wireless system is determined. In response to at least the trigger event, the status of the setting for warning notifications is automatically presented through the UE.

Description

Method and apparatus for managing alert notifications

The present application claims the priority of the International Application No. PCT/IB2011/002488, filed on Aug. 5, 2011, the entire disclosure of which is hereby incorporated by reference.

Different systems are used in the world to deliver emergency notifications to people. This allows the individual to receive one (possibly escaped) alert message sent by the network in a point-to-multipoint manner. For example, currently, in Japan, the ETWS (Earthquake and Tsunami Warning System) system is used in the Universal Mobile Telecommunications System (UMTS) (corresponding to the 3GPP work item ETWS). This system relies on older cells broadcasting older technologies (CBS, see TS 23.041). ETWS was introduced in 3GPP Rel-8. The Commercial Action Alert System (CMAS) was introduced in Rel-9. CMAS and ETW's 3GPP work items are put together to form a Public Alert System (PWS) work item. This is also defined in 3GPP LTE.

In general, there is a regrettable possibility in any emergency notification system in the world, such as a fake network sending a fake (non-real) alert notification to the user. The fake network can be created by, for example, a prankster to create a panic by sending a fake alert message. These warning messages can be any message such as "Fire in the theater, hurry to leave!" As an example, such messages can cause public panic, and if people try to rush away from a crowded place, the public panic will be harmful to people. There may be some network authentication security schemes to allow the device to discover false messages and, for example, to display false messages. Although such security schemes may be "cracked" by non-real sources, the network may not have implemented such security schemes (for example, in a deployment scenario), Or the network has not activated this security.

For ETWS, level 1 in Rel-8 is defined in TS 22.168. For PWS, level 1 starting at Rel-9 is defined in TS 22.268. For UMTS (as built on CBS), level 2, which defines UE behavior, is defined in 23.041, and in general, level 2 TS 23.401 is used for LTE. When the ETWS is initially specified in Rel-8, the intent is that this may contain certain security features to alert the potential fake network.

However, since the authentication network for the point-to-multipoint scheme is basically different from the authentication for a network for the point-to-point scheme (because it already exists in 3GPP), this scheme is not completely completed according to standards. Introducing a "digital signature" and "time stamp" in these standards and possibly causing the network to signal the digital signature and time stamp to the device; however, no digits are defined in the standards. Signature algorithms, such as how to manage security keys. This omission is confirmed by 3GPP (see S3-110148), and work group SA3 has started a new Rel-11 work item (see S3-110204) for this purpose, whose target is to define and introduce network authentication for PWS. One (may be completely different) security.

Therefore, it is possible that the current security at the appropriate location in the Rel-8 standard may not be used, and basically the "digital signature" or "time stamp" context should not prevent the display of a warning message in the device behavior (see CT1, SA1, SA2 in SA3 to S3-110852 reply LS, and reply to CT1 LS C1-112199). This is because, in some other way, for some reason, due to incomplete security, the device identifies the security as invalid or incomplete. Integrity, there is a risk that a real escape message will not be displayed to the user due to security incorrectly preventing it from being presented. Therefore, since personal security is better than security, 3GPP will tend to always display warning messages about digital signature/timestamp security. In practice, this means that the text associated with the digital signature and time stamp can be removed from Rel8/rel-9/Rel-10 in TS 23.041 (UMTS) and TS 23.401 (LTE) (in some cases, This text prevents the message from being displayed). In another scenario, regardless of any removal or change in the specification, a network can simply decide not to use this security. Therefore, this raises a question. 3GPP confirmed that the re-introduction of security for PWS will not be performed until Rel-11 (the related SA3 work item is Rel-11), so Rel-8/Rel-9/Rel-10 may not exclude a fake Network and fake alert messages.

In general, it cannot be ruled out that on any alert notification system in the world (and for any version), the security system is cracked by a non-real source or the (real) network does not implement the network authentication security part or decides not to start this. Security, so that users have the risk of receiving a false alert notification.

As for the ability to disable PWS, since Rel-8, there is a possibility in the level 1 that the user disables the PWS alert message reception/display. This is basically one of the user's operations to turn the switch on/off. Level 1 TS 22.168 (Rel-8) and TS 22.268 (Rel-9, Rel-10) specify that the default settings for this "switch" should be enabled. It should be possible to extract from the excerpt of TS 22.268 that “users are subject to regulatory requirements and/or operator policies and are deactivated (eg, opt-out) to present some or all of the alert notices in the alert notice. The user should be able to respond Select PWS-UE via user interface for some or all alert notifications Enable/disable option to disable or enable PWS-UE behavior later. Including this rule allows life alert messages to always be received by the user by default. It is not expected that a user needs to search the user manual for how to start PWS, or even worse, one of the "deactivated" settings may result in no possibility of receiving an escape message. The user will not be aware of the deactivated feature. Although in order to solve the problem that the Rel-8/Rel-9/Rel-10 warning notice can be maliciously used, SA3 proposes (in reply to LS S3-110852) the following items: (1) Change the preset setting to "stopped" Use (at the plant factory); and (2) change the nuance of this setting to a public land mobile network (PLMN) basis compared to an overall setting. In such cases, at the factory, the device is pre-configured to include a list of all networks (PLMNs) that effectively use the PWS. For example, if PWS/ETWS is used in Japan and not in the UK or France, the setting will be "Connected" for NTT DoCoMo Japan and "Shutdown" for Vodafone UK and "SFR France". No fake messages can be displayed on the Vodafone UK network or the SFR France network. However, the manufacturer is not aware of the complete list of PLMNs using PWS in the world (also considers the fact that this list changes over time), and the list of "on/off settings" and corresponding PLMN IDs will be limited.

A mobile communication device, such as a cellular mobile station, can be capable of making and receiving telephone calls and/or transmitting and receiving data over a wireless communication network. Before the mobile station is able to do this, the mobile station selects and attempts to register with one of a plurality of communication networks available within its geographic coverage area. After selecting a PLMN, the mobile station operates in its idle mode, which resides in one of the particular wireless communication channels. If there is a successful PLMN registration, the mobile station Monitor calls or messages. If the PLMN registration is unsuccessful, the mobile station can still monitor the emergency call or alert notification. In general, the PLMN selection includes a communication network through which the mobile station selects to register and operate.

The cellular telephone operation and the PLMN selection scheme are documented in the standard specifications governing the behavior of the cellular mobile station and associated systems. A well-known cellular standard is the Global System for Mobile Communications (GSM) standard. GSM 03.22/European Technical Standards Institute (ETSI) TX 100 930, Technical Specification (TS) 23.122 from 3.sup.rd 3rd Generation Partnership Project (3GPP) and other related standard specifications describe cellular operation and network selection Many details. These documents describe the behavior of a mobile station as it moves and roams between regions and countries to maintain coverage of the network (eg, public land mobile network or PLMN), primarily for the provision of continuous telephone calls. The purpose of the service.

[Embodiment] A system and a method for deactivating or enabling the presentation of a Public Alert System (PWS) notification to a User Equipment (UE). The term UE is a generic term for user equipment that may equally encompass, for example, a mobile station (MS), a mobile device (ME), and others. For example, the UE may respond to at least one triggering event to indicate whether to enable or disable one of the alert notifications to be presented to the user. Following this, the user can use the UE update to present or not present one of the received notification settings. This will allow a user not to misidentify the status of the settings. Therefore, in a country where PWS is used, the user can therefore ensure that the PWS is set to "enable" in this country (to ensure receipt of escape notifications) and in a country that does not use PWS, PWS Set to "deactivated" in this country (to ensure no false messages are received). It should be noted that in other ways, in the case where the state of the setting is not automatically indicated to the user, one of the "deactivated" states in one of the countries not using the PWS can remain unnoticed by the user. And if the UE roams later to use one of the PWS countries, the UE will not be able to notify the user of the escape alert notification, and the user may not know about it and is unaware that it needs to change the settings. In some embodiments, a triggering event may include registration to a PLMN (success only, or success and unsuccess), a PLMN selection, a PLMN registration without one of the PLMN changes (success only, or success) And unsuccessful) or selection, handover in one of the connected modes, one of the service selections in a current PLMN, one of the cells in a current PLMN, to one of the cells in a different PLMN Change, other events, or a combination of the foregoing. In some embodiments, the UE can automatically present a notification as to whether one of the alert notifications is enabled or disabled in the device. For example, the indication can be made when the device resides in a PLMN for an emergency, when the device registers with a PLMN, or both. In this way, the user will know if he can anticipate a warning message and will know that if the setting is incorrectly set to "off", the setting must be turned "on" (and vice versa).

The above operations can be reapplied to the user settings for alert notification enable/disable to be modified to have a finer than a general "on/off" switcher and/or accessed by the home network or accessed In the context of the network (which may otherwise become a user setting) control. For example, this can be reapplied to scenarios in which user settings for alert notification activation/deactivation are applied on a PLMN basis. In this case, the device can be enabled The deactivation alert message is also automatically indicated to the user, in particular for the PLMN corresponding to the cell in which the device resides. The UE may indicate any combination corresponding to the state of the registered network, the state of the selected network, or any of its states. In this case, the automatic indication of the UE display status corresponding to the PLMN in which the UE is located at the time may be even more useful, since the user may not remember how to set this for each country UE manufacturer, or for each country. How the user has modified this (for example, if a user has modified the settings in a country a few years ago and returns to the country several years later).

If the nuances of the "on/off" setting are different between different types of warning messages (some of which can be enabled for certain message categories or message types and other message categories or message types are disabled), then the above operation can also be performed. Reapply. In this case, more than one status can be indicated to the user (one distinct state per message category). For example, CMAS distinguishes between the following types of alert messages (or types of alerts): (1) urgent threat alert notifications; (2) child abduction emergency alert notifications; or (3) presidential alert notifications. Therefore, it would be possible to use one of the two categories of messages (for example) between message types (1) + (2) and (3). In addition, any other combination of categories is possible without departing from the scope of the invention. Additionally, a difference in the type of message used in conjunction with the granularity on a PLMN basis may result in having one or more settings mapped to each PLMN ID.

Turning to one of the descriptions of the environment, FIG. 1 illustrates updating an alert notification in accordance with certain embodiments of the present invention (including embodiments for applying user settings for alert notification activation/deactivation on a PLMN basis). One example system 100. As illustrated, system 100 includes a configuration to interact with The UE 104 communicates with one of the first PLMN 102a and one of the second PLMN 102b. The PLMN 102 includes a base station 106 for wirelessly communicating with the UE 104, which may have a signal coverage area represented by a dashed line 108 portion. In some embodiments, the UE 104 can perform one or more of: identifying one of the trigger events associated with a PLMN 102; determining one of the PLMNs 102 identification code or PLMN ID; capturing the identified PLMN ID and Information indicating a mapping between the activation of the alert notification of the associated PLMN 102; one of the UE enable/disable states of the alert notification indication for the corresponding PLMN 102 is automatically presented to the user via the UE 104; the receiving UE 104 One of the users requests to update one of the settings associated with the alert notification; or in response to at least the request, the UE 104 is updated to enable or disable the presentation of the alert notification. By presenting the ability to enable/disable state in the UE corresponding to PLMN 102, the user can be notified whether the setting is different from the usage setting (e.g., on the home PLMN) and thus will be able to change this setting if desired. In addition, the information can be automatically presented to the user to avoid situations in which the user has disabled the settings but does not remember this.

Turning to a more detailed description of one of the components, the PLMN 102 wirelessly communicates using the base station 106. In some embodiments, PLMN 102 can include a plurality of base stations 106. In some embodiments, PLMN 102 is in network communication with one of the interfaces providing connectivity to other wireless communication systems and wired communication systems. The PLMN 102 can communicate with the UE 104 using wireless techniques such as one of the following wireless technologies: orthogonal frequency division multiplexing (OFDM), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple storage. Take (SC-FDMA), discrete Fourier transform extended orthogonal frequency division multiplexing (DFT- SOFDM), space division multiplexing (SDM), frequency division multiplexing (FDM), time division multiplexing (TDM), code division multiplexing (CDM) or others. A wireless communication system can use a Media Access Control (MAC) and a Physical (PHY) layer to transmit information. In addition, PLMN 102 may be a variety of wireless communication systems such as systems based on one of: Long Term Evolution (LTE) Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA), Universal Mobile Telecommunications System (UMTS), Unlicensed Action Access (UMA) or other. As mentioned previously, PLMN 102 can be assigned a PLMN ID or otherwise associated with a PLMN ID. In some embodiments, PLMN 102a may have a different PLMN ID than one of the PLMN IDs assigned to PLMN 102b. Additionally, the PLMN 102 can execute the PWS such that an alert notification can be transmitted to the UE 104. In these examples, the settings corresponding to each PLMN 102 can be mapped to an associated PLMN ID. Access/reject (from, for example, access to the network (for example, from a broadcast channel, BCCH) or from a core network (for example, accept or reject messages from location registration, location accept/reject, or routing area updates) See TS 24.008), or Tracking Area Update Accept/Reject (see TS 24.301) or receive a PLMN ID from a Cell Broadcast Center or Cell Broadcasting Entity. More than one PLMN ID can be considered to cover the case of network sharing (eg, multiple carrier core networks MOCN) or equivalent PLMNs.

The UE 104 may include any software, hardware, firmware, or a combination of the foregoing, configured to automatically present whether to enable/disable the UE for providing alert notifications such as PWS. Alternatively, in an embodiment, the UE 104 may include any soft configured to automatically render whether to enable/disable the UE for providing such alert notifications upon receipt of an alert notification such as PWS by the PLMN 102. Body, hardware, firmware or a combination of the foregoing. The UE settings corresponding to the PLMN 102 may be presented through one of the UE's displays, a sound (eg, voice indication), a vibration, or a combination of the foregoing. For example, the UE 104 may display a text such as "Alarm notification is enabled in this device - Please check the settings to change this" or "The alert notification is disabled in this device - Please check the settings to change this". This indication can remain on the screen until the user acts or automatically disappears after a period of time. Similarly, the UE 104 may wait for a predetermined period of time or wait until the triggering event has been completed before displaying the indication. In some embodiments, this indication can be performed in an "asymmetric manner" between two possible states. For example, the indication of the state of self-enabling may be displayed on the device (or vice versa) greater than the indication of the state of self-deactivation, or the indication may remain longer/shorter on the screen. In some instances, the indication may only be displayed for a particular state, such as only an alert notification is enabled or only an alert notification is disabled. Alternatively or additionally, the UE 104 may present settings and alert messages using other techniques such as, for example, voice instructions for blind users.

As mentioned previously, the UE 104 may present a notification in response to a triggering event such as one of: registration with a PLMN (successful/unsuccessful registration or only successful registration), a PLMN selection, one of no PLMN changes In the case of a PLMN registration and/or selection, a PLMN registration and/or selection in case one of the PLMNs changes, in one of the connected modes, in a connected mode to a different PLMN One of the new cells is handed over, one of the services in a current PLMN, one of the cells in a current PLMN, one of the cells to a different PLMN, the other An event or a combination of the foregoing. For example, the notification may be presented to the user in the PLMN registration rather than the PLMN selection or in some PLMN registration and/or PLMN selection in the PLMN registration and/or PLMN selection. The triggering event may include a PLMN selection involving one of the changes of the PLMN 102 (i.e., the selected PLMN 102 is different from the last selected PLMN 102). In some embodiments, the triggering event can include a PLMN registration that involves changing one of the PLMNs 102, such as the registered PLMN different from the last registered PLMN 102. In some embodiments, the triggering event can include one of the PLMN selections when the selected PLMN is not the native PLMN 102 (ie, is a visited PLMN 102). In other words, the UE 104 roams. In some embodiments, the triggering event can include one of the PLMN registrations when the registered PLMN 102 is not the native PLMN 102. In certain embodiments, the triggering event can include a modified and/or introduced SIM/USIM. This is used, for example, in conjunction with a trigger for PLMN selection with PLMN changes: PLMN selection with PLMN changes and/or PLMN selection with SIM/USIM changes. If the UE has previously switched to ON in the factory (eg, for testing purposes), this embodiment may allow the user to see the indication at least once when the UE is first switched on. In some embodiments, the triggering event can include one of the PLMN registrations when the registered PLMN 102 is a native PLMN 102. In some embodiments, the triggering event can include one of the PLMN selections when the selected PLMN is a native PLMN. In some embodiments, the triggering event may be that the UE camps on a cell belonging to one of the PLMNs that is different from the previously camped cell. In some embodiments, the triggering event may include one of the successful location registrations from TS 24.008 (Location Area Update or Routing Area Update) or from TS 24.301 The success of the tracking area update, which results in a change in one of the PLMN or the registered PLMN. The triggering event may include an unsuccessful procedure that results in a change in the PLMN or the registered PLMN. According to all of the examples in this application, the trigger may be affected by the fact that the PLMN is the home PLMN or the visited PLMN. For example, the triggering may include causing one of the PLMNs to change one of the successful location registrations only if the new PLMN is one of the visited PLMNs. The above triggering events are for illustrative purposes only and the triggering event may include any of these examples, any combination, all instances, or none of these examples without departing from the scope of the invention. One. Certain restrictions may be added such that if the combination of triggers may result in multiple indications or multiple indications (possibly for the same PLMN) in a limited time, only some of the indications may be presented. Certain restrictions may be added such that if the same trigger results in multiple indications in a limited time, only some of the indications or an indication may be presented. For example, reusing an instance of a triggering event that includes a successful PLMN registration from the above in the case of a PLMN change, the UE may not perform the indication if the successfully registered PLMN was previously registered for less than a predetermined duration. This omission avoids a ping-pong between the two networks that are frequently displayed to the user. The duration can be pre-set by the user (reflecting a value of 0 or positive infinity is also possible, which would mean not requesting one of the restrictions or requesting one of the states, respectively). Note that these implementations are only one example and "time limit" can be applied to any of the other examples described above (PLMN selection, etc.). In some enhancements, the user will likely enable/disable this automatic indication.

In some embodiments, the UE 104 can present a device set state (alert notification enable/disable) during both the connected mode and the idle mode. For example, the condition for triggering the display of information to the user may be when the device performs a new cell-to-delivery (inter-PLMN handover) from a different PLMN 102. Although the term handover is used, the UE 104 can present information in response to any message/command from the PLMN 102 associated with the handover between the PLMNs. In addition, the condition of the trigger may be caused by any one of the PLMN changes (in the idle and/or connected mode or any other mode) (except, for example, cell reselection) and/or the condition of the trigger may be Any UE action that causes the PLMN to become a change in one of the visited PLMNs (or cause the PLMN to become one of the changes to the home PLMN). Again, they can be used together with their triggers. For example, when a successful location registration from TS 24.008 (Location Area Update or Routing Area Update) or a tracking area update from TS 24.301 results in a change in one of the PLMN or the registered PLMN. In some embodiments, the triggering event may be that the device has performed a cell reselection or cell change (in idle mode and/or connected mode) to one of the new cells in a different PLMN 102. In some embodiments, the triggering event can include one or more of the scenarios set forth above, even if the set nuance is an overall on/off setting and is not necessarily one of the settings per PLMN.

One of the overall settings determined by the user can enable or disable the automatic presentation of the status of the alert notification. In other words, the UE 104 can receive a request to enable or disable the presentation of the set status to the user. This setting of the auto-indication of the update enable/disable can be limited to affect only when the UE is roaming (not in the hometown) Automatic indication provided in PLMN). Alternatively, it may be defined as affecting the automatic indication provided only when the UE is not roaming. Alternatively, it may be defined as an automatic indication that affects only "enabled". Alternatively, it may be defined as an automatic indication that affects only "deactivated" indications. Other combinations of restrictions or previous restrictions may be considered. The value of this overall setting can also be modified by the home PLMN or a visiting PLMN via OMA-DM or dedicated signaling. In some embodiments, information regarding the "message display settings" of the considered PLMN 102 can be presented to the user of the PLMN 102 that the UE 104 camps but is after a user action. Instead of providing a large list of PLMNs with the status of the PLMN, the UE 104 may indicate the UE 104 after the user has selected a given menu option, has performed a given action, has pressed a predetermined button, other actions, or a combination of the foregoing actions. The status of the PLMN 102 (or selected PLMN 102 or registered PLMN 102) of the camped cell.

It should be noted that although the examples in this document may be related to 3GPP ETWS, CMAS or PWS for UMTS or LTE, it is not excluded that the examples, methods or solutions set forth in this document are re-applied for Or 3GPP GERAN not based on the alert notification of the Cell Broadcast Service (CBS). Similarly, this is not limited to 3GPP and it is possible to reuse any of their concepts, methods or solutions for other systems such as those based on the IEEE or IETF standards. For example, other systems may include an IETF authority to a population alert (atoca) work group, by the standards body ATIS (for example, by the WTSC committee and the G3GSN and JCMAS subcommittees, for example, using broadcast SMS) By the TIA standards body (for example, TR45.5), by the ETSI EMTEL committee, by the EU-alarm system and/or Or systems developed by other systems or committees.

In general, the UE 104 can receive and transmit wireless and/or contactless communications with the system 100. As used in the present invention, the UE 104 is intended to include a cellular phone, a data phone, a pager, a portable computer, a SIP phone, a smart phone, a personal data assistant (PDA), a digital camera, an MP3 player, a video camera. One or more processors within, or other devices, or any other suitable processing device capable of communicating information with PLMN 102. In some embodiments, the UE 104 can be based on a cellular radio technology. For example, the UE 104 can be operative to wirelessly connect one of the PDAs to an external or unprotected network. In another example, the UE 104 can include a smart phone that includes one of the input devices, such as a keypad, touch screen, mouse, or other device that can receive information, and communicates with one of the PWSs that are associated with the PLWS 102. One of the output devices of the information (including digital data, visual information or graphical user interface (GUI) 110).

The GUI 110 includes a graphical user interface that is operable to interface with at least a portion of the system 100 for any suitable purpose of enabling the user of the UE 104 to enable the activation of an alert notification, such as an authorization. In general, the GUI 110 provides an efficient and user-friendly presentation of one of the materials provided by or within the system 100 to a particular user and/or will be provided by the PLMN 102 for user self-management settings and access. One of the services is efficient and user friendly components are provided to specific users. The GUI 110 can include a plurality of customizable frames or views having interactive fields, drop down lists, and/or buttons operated by the user. The term graphical user interface can be used in singular or plural form to describe one or more graphical user interfaces and a particular graphical use. Each of the displays of the interface. The GUI 110 can include any graphical user interface, such as processing information in the system 100 and presenting the results to one of the user's general purpose web browsers or touch screens.

2A and 2B illustrate an exemplary PLMN 102 and Cell Broadcast Center (CBC) 252 based on a Universal Mobile Telecommunications System (UMTS). Referring to FIG. 2A, PLMN 102 includes a UMTS-based Radio Access Network (RAN), referred to as a UTRAN and a 3GPP GPRS Packet Switching Core Network. The core network provides connectivity to an external network, such as one of the Internet 240. The PLMN 102 includes one or more base stations (such as Node B base stations 210a, 210b) that provide wireless services to one or more devices, such as the UE 205. A Radio Network Controller (RNC) 215 can control the Node B base stations 210a, 210b. The RNC 215 and the Node B base stations 210a, 210b form a RAN. PLMN 102 may include system elements 220, 225, 230, 235 that perform one or more communication functions, such as connection establishment and data routing. For example, the system includes a Serving GPRS Support Node (SGSN) 220 that is responsible for routing one of the communications within a core network. The system includes a gateway GPRS Support Node (GGSN) 235 that is responsible for enabling incoming/outgoing traffic to/from the Internet 240. The GGSN 235 can assign an IP address to the UE 205.

For a UMTS-based system, the network interface includes a Uu interface defined between a UE and a Node B, an Iub interface defined between a Node B and an RNC, and an Iu defined between an RNC and an SGSN. The interface, the Gn interface defined between an SGSN and a GGSN, and the Gi interface defined between a GGSN and an external packet data network. User plane connectivity through the radio access network and the core network may require networking between Path interface: between the UE and the Node B (for example, the Uu interface), between the Node B and the RNC (for example, the Iub interface), between the RNC and the SGSN (for example, the Iu interface), between the SGSN and the GGSN (for example, the Gn interface) and between the GGSN and the Internet (for example, the Gi interface). The establishment of one or more of such network interfaces may be associated with one of the radio connection states or sub-states as a function of current activity levels. For example, Uu, Iub, and Iu connections can be established only when active user plane data communication is required.

Referring to FIG. 2B, a basic network structure 250 of a Cell Broadcast Center (CBC) 252 is illustrated. The basic network structure 250 can replace the GSM BSS with a UTRAN containing RNC 254 and Node B 256. The Cell Broadcast Center (CBC) 252 is part of the core network and is connected to the routing node via a Bc reference point, such as a 3G SGSN. Therefore, CBC 252 can reach RNC 254 via the Iu interface. A mandatory agreement can be defined at the logical interface between CBC 252 and RNC 254. Other UTRAN related interfaces are set forth in the corresponding UTRAN specification based on RAN 2 3GPP TR 25.925. Based on this architecture and the current requirements for cell broadcast, service delivery may not involve core network elements such as MSC, VLR, HLR, and others.

3A and 3B show an example PLMN 102 based on Long Term Evolution (LTE). Referring to FIG. 3A, PLMN 102 includes a core network called an evolved packet core (EPC) and an LTE radio access network, such as an evolved UTRAN (E-UTRAN). The core network provides connectivity to an external network, such as one of the Internets 330. The PLMN 102 includes one or more base stations (eNodeB (eNB) base stations 310a and 310b) that provide wireless services to one or more devices, such as the UE 305.

An EPC-based core network can include a Servo Gateway (SGW) 320, a Mobility Management Endpoint (MME) 315, and a Packet Gateway (PGW) 325. The SGW 320 can route traffic within a core network. The MME 315 is responsible for the core network mobility control attachment of the UE 305 to the core network and maintaining contact with the idle mode UE.

FIG. 5 is a flow diagram illustrating one example method 500 for presenting alert notifications for a PLMN. The illustrated method 500 is illustrated with respect to system 100 of FIG. 1, but any other suitable system can use this method. Moreover, system 100 can perform such tasks using any other suitable technique. Thus, many of the steps in the steps of the flowcharts can occur simultaneously and/or occur in an order different than the ones shown. System 100 can also use methods with additional steps, fewer steps, and/or different steps, but such methods remain appropriate. In addition, the method 500 is directed to an embodiment having a setting on a per-PLMN basis in the UE and the system 100 can have settings based on other subtleties without departing from the scope of the present invention.

The method 500 begins at step 502 where the UE 104 is turned "on" or otherwise activated. At step 504, the UE 104 performs one of the cells of the PLMN 102. PLMN selection. For example, the UE 104 may store a preset PLMN 102 or one or more attributes of the PLMN 102a and PLMN 102b that may be determined to make a selection. Next, at step 506, the UE 104 transmits a PLMN registration request to the selected PLMN 102. At step 508, the UE 104 receives a registration response. In certain embodiments, method 500 can be implemented when registration is unsuccessful, such as when emergency services are used, without departing from the scope of the invention. At step 510, the UE 104 identifies the PLMN ID of the selected PLMN 102 based at least in part on the information broadcast by the PLMN 102, the information provided by the core network (eg, MSC, SGSN, MME) of the PLMN 102 and / or information provided by a cell broadcast center or a cell broadcast entity. Next, at step 512, the UE 104 retrieves a mapping between the PLMN ID and the UE settings for alert notifications from the memory (or SIM/USIM). For example, the UE 104 may store a table that matches the PLMN ID to indicate whether an alert notification is indicated to the user of the PLMN. At step 516, the UE 104 determines the alert notification setting for the UE of the selected PLMN 102 based at least in part on the mapping and the broadcasted PLMN ID. Note that if the UE setting is not based on a PLMN, the UE does not need to perform a mapping between the PLMN ID and the UE setting of the PLMN. The UE 104 identifies an event at step 518 and identifies a plurality of trigger events at step 520. Next, at step 522, the UE determines that the event matches at least one of the plurality of trigger events. At step 524, the UE 104 automatically presents the alert notification capability to the user.
