 Various non-limiting embodiments of the invention are described in detail below with reference to the drawings.

 1 is a schematic diagram of a network topology structure in accordance with an embodiment of the present invention. Figure 1 illustrates an application of the present invention in an IP Multimedia Subsystem. Of course, those skilled in the art should understand that the present invention is not limited only to an IMS network, and the present invention is applicable to various networks that can support presentation information. For example, the traditional Internet and the like. Various network functional entities related to the present invention are shown in FIG. In the IP multimedia subsystem network represented by the cloud diagram in FIG. 1, the following functional entities are shown, a proxy CSCF (Proxy-Call Session Control Function, P-CSCF, proxy call session control function), and a query CSCF (Interrogating-Call Session Control) Function, I-CSCF, Query Call Session Control Function), Serving Call Session Control Function (SCF), Home Subscriber Server (HSS), Application Server, Presentation Server 3 (Presence Server, PS).

 Wherein, when the mobile terminal obtains the IMS service, the proxy CSCF is the first contact node. The user terminal obtains the address of the proxy CSCF through a "local CSCF discovery process". The proxy CSCF acts like a proxy server, which processes or forwards received requests and services.

 Query CSCF can act as a connection point for all users of the network, or as a service access point for roaming users in the current network service area.

 Service CSCF performs session control functions. It maintains session state information based on the needs of the network operator.

 The home subscriber server is a database of subscriber and service information that supports the CS domain, the PS domain, and the IMS subsystem.

It is further shown in FIG. 1 that the serving CSCF and the application server communicate with each other through an ISC interface based on the SIP (Session Initiation Protocol) protocol. The service CSCF communicates with the HSS through the Cx interface based on the Diameter protocol; the HS S and the application server exchange information through the Sh interface based on the Diameter protocol.

 Proxy CSCF, Query CSCF, and Service CSCF specific functions are defined in existing protocols. In addition, those skilled in the art can refer to related reference books, such as "3G Core Network Technology" published by National Defense Industry Press ( ISBN 7-118-04056-8) or "IP Multimedia Concept of Mobile Field" published by Mechanical Industry Press. And services" (ISBN 7-111-15835- 0/TN-404) and so on. Therefore, it will not be described here.

 The user terminal 2a is also shown in FIG. The user terminal 2a is a mobile phone. Of course, the user terminal can also include a Personal Digital Assistant (PDA), a notebook computer, and the like.

 2 shows a network device in a network in which a subscriber 2b is located in a specific embodiment of the present invention, and performs a method flow for implementing the present invention to provide presence information to the subscriber 2b in the S-CSCF1. Description. The service CSCF 1 shown in Fig. 2 is an example of a "network server" which is merely a functional entity for implementing the business logic introduced by the present invention. Of course, the business logic introduced by the present invention can also be implemented on a separate network server other than the service CSCF 1, or can be integrated with other servers, for example, integrated on the presence server 3 (PS) or other network server or Implemented in the application server, it can also be a new independent dedicated server. The above S-CSCF1 is merely exemplary, and those skilled in the art can understand that other network devices can implement the above functions as long as they are network nodes located before the terminal device of the subscribing user 2b.

 In the following specific embodiment, the user terminal 2a, as the publisher of the presence information, is the source of the presentation information, and is hereinafter referred to as the presentation information source 2a. Only the home network in which the user terminal 2a is located is shown in Fig. 1, and the user terminal 2b is also shown in Fig. 2. In an actual network, the user terminal 2a and the user terminal 2b may be located in the same network or in different networks. The user terminal 2b serves as a subscriber of the presence information, and is therefore referred to as a subscriber 2b hereinafter.

2 shows a flow chart of a method in accordance with an embodiment of the present invention. First, in step SA, the presentation information source 2a provides the presentation information to the presence server 3. It can be understood by those skilled in the art that in order to provide the presence information to the presence server 3, the presence information source 2a needs to be forwarded by the P-CSCF and the S-CSCF in the home network where the information source 2a is located, and then the presentation information can arrive at the presentation. Server 3. Since the home network in which the information source 2a is present is not highly relevant to the present invention, the P-CSCF and the S-CSCF in the home network of the present information source 2a are omitted in FIG. 2 by the dotted arrow of step SA, only The presence server 3 is shown.

 Then, in step S20, the S-CSCF 1 acquires the processing trigger condition configured by the subscribing user 2b, and acquires the presentation information issued by the presentation information source 2a from the presence server 3. The processing trigger condition is used to determine whether the S-CSCF1 needs to process the presentation information to be sent to the subscribing user 2b, and obtain the presentation information to be sent to the subscribing user.

 For example, the subscribing user 2b may process the triggering condition based on a user interface setting such as a webpage, a touch screen, or the like. The triggering condition may be determining whether the S-CSCF1 needs to be triggered to process the presence information according to the attribute of the presence information from the presentation information source, or may be based on the subscription. The attribute of the user 2b determines whether it is necessary to trigger the S-CSCF1 to process the presence information.

 A. Judging based on the attributes of the presence information from the presentation source

 The processing trigger condition sent by the subscribing user 2b to the S-CSCF1 may be any of the following:

 - judging whether the size of the presentation information to be sent to the subscribing user 2b exceeds a predetermined value, and if the size of the presentation information to be transmitted to the subscribing user 2b exceeds a predetermined value, the presentation information to be sent to the subscribing user 2b needs to be processed;

 - judging whether the presentation information to be sent to the subscribing user 2b includes the predetermined content, and if the presentation information to be transmitted to the subscribing user 2b includes the predetermined content, the presentation information to be transmitted to the subscribing user 2b needs to be processed;

 - judging whether the transmission frequency of the presentation information transmitted from the presence information source 2a by the presence server 2b to the subscribing user 2b exceeds a predetermined frequency; if the presentation frequency of the presentation information transmitted from the presence information source 2a by the presence server 2b to the subscribing user 2b exceeds a predetermined Frequency, the presentation information to be sent to the subscription user 2b needs to be processed;

- judging whether the time at which the presentation server 3 sends the presence information to the subscribing user 2b belongs to For a predetermined period of time; for example, the subscribing user 2b may set a predetermined period of time from 11:00 pm to 6:00 am, which is not desirable to receive presence information, if the time at which the S-CSCF1 receives the presence information falls within the predetermined time period. Then, the presentation information to be sent to the subscribing user 2b needs to be processed.

 Certainly, those skilled in the art can understand that the above predetermined value, predetermined frequency, and the like may be configured by the network operation and maintenance personnel according to actual network operation conditions, or may be automatically adaptive, or a default value.

 B. Determine whether trigger processing is required based on the attributes of the subscribing user 2b

 - determining based on the status information of the subscribing user 2b, for example, when the status information of the subscribing user 2b is busy or leaving or in a conference, the presentation information to be sent to the subscription user 2b needs to be processed;

 - judging based on the load of the subscribing user 2b, for example, determining whether the subscribing user 2b is overloaded. Specifically, it can be determined that the traffic received by the subscribing user 2b within a predetermined time interval exceeds a predetermined threshold, and if the subscribing user 2b is overloaded, the The presentation information to be sent to the subscribing user 2b is processed;

 - Judging based on the capability of the subscriber of the subscriber 2b, for example, the processing capability supported by the subscriber 2b, including but not limited to the CPU, memory, network connection, modulation and coding mode, software processing capability, and support used by the subscriber 2b Language, display resolution, etc. For example, if the presentation information provided by the presentation information source is Japanese, and the language supported by the subscription user 2b is Chinese and English, the presentation information to be sent to the subscription user 2b needs to be processed; or

 - based on the location information of the subscribing user, for example, the subscribing user 2b wants to display the presence information only when he is at home, and does not want to display the presence information when he is at the office or on the go, and can determine the location information of the subscribing user, if the subscribing user 2b is at home, Providing the presence information to the subscribing user 2b. Otherwise, if the subscribing user 2b is in the office, the presentation information to be sent to the subscribing user 2b is processed, for example, discarding the presentation message.

- Based on the personalized setting of the subscriber 2b, for example, whether the subscriber 2b needs to reduce the traffic on the user side, if the subscriber 2b needs to reduce the traffic on the user side, it is judged that the presentation information to be sent to the subscriber 2b needs to be processed. These processing trigger conditions can be stored in an existing Home Subscriber Server (HSS), and of course, can also be stored in a dedicated server.

 Then, in the step, the S-CSCF1 determines whether the processing trigger condition configured by the subscribing user 2b is satisfied according to the presentation information to be sent to the subscribing user.

 First, the processing trigger condition configured by the subscribing user is an attribute judgment based on the presence information of the presentation information source as an example.

 For example, the trigger condition is to determine whether the size of the presence information to be sent to the subscribing user 2b exceeds a predetermined value. If the size of the presentation information to be sent to the subscribing user 2b exceeds a predetermined value, then in step S220, the S-CSCF1 is to be sent to The presence information of the subscribing user 2b is processed, for example, the S-CSCF1 may discard the presence information; otherwise, in step S22, the S-CSCF1 directly provides the presence information to be sent to the subscribing user 2b to the subscription through the NOTIFY message. User 2b, specifically, S-CSCF1 first sends the presence information to the P-CSCF, and then forwarded by the P-CSCF to the subscribing user 2b;

 For another example, the S-CSCF1 may further determine whether the presentation information to be sent to the subscribing user 2b includes predetermined content, and the predetermined content may be some sensitive words set, or keywords, which are set in the server of the S-CSCF1. Some interfering words, such as "invoice", "smuggling", "villa home open" and other words as sensitive words, when the above sensitive words appear, the S-CSCF1 needs to send the presentation information to be sent to the subscribing user 2b. Processing, for example, discarding the presence information of the sensitive words; or masking the keywords in the message, for example, deleting the words "invoice", "smuggling", "opening of the villa", and then The processed message is provided to the subscribing user 2b through the NOTIFY message; otherwise, if the S-CSCF1 determines that the presentation information sent to the subscribing user 2b does not include the predetermined content, then in step S22, the S-CSCF1 is to be sent to the subscribing user. The presentation information of 2b is directly provided to the P-CSCF through the NOTIFY message, and then provided to the subscribing user 2b by the P-CSCF through the NOTIFY message.

In another specific embodiment, the S-CSCF1 can also determine whether the transmission frequency of the presence information sent by the presence server 3 from the presence information source 2a to the subscribing user 2b exceeds a predetermined frequency; if the presence server 3 sends the notification from the subscribing user 2b If the transmission frequency of the presentation information of the presentation information source 2a exceeds a predetermined frequency, the presentation information to be sent to the subscribing user 2b needs to be processed, which may be found when the S-CSCF1 finds From presenting information source ² a presentation transmission information exceeds a predetermined frequency, e.g., within a fixed time interval from the presence information sources presenting information exceeds a predetermined threshold value 2a, the S-CSCF1 according to a predetermined configuration, discarding subsequent The presence information from the S-CSCF1 to the subscribing user 2b, of course, in another embodiment, the S-CSCF1 may also present the presentation information from the presentation information source 2a after the fixed time interval to a predetermined The reduced frequency is transmitted, for example, the presence information from the presentation information source 2a is sent to the subscribing user 2b every 1 hour, and the presence information received from the presentation information source 2a at other times is discarded.

 In another specific embodiment, the S-CSCF1 can also determine whether the time at which the presence server 3 sends the presence information to the subscribing user 2b belongs to a predetermined time period; for example, when the trigger condition is the subscription user 2b, 11:00 to 6 in the evening. When the point is set to a predetermined time period in which it is not desired to receive the presence information, if the time at which the presentation information received by the S-CSCF 1 falls within the predetermined time period, the presentation information to be transmitted to the subscription user 2b needs to be processed. For example, in step S220, the S-CSCF1 discards, for example, the presence information to be sent to the subscribing user 2b at 2 o'clock in the morning.

 In the above, the presentation information from the presentation information source 2a is controlled and processed for the content of the presentation information and the transmission characteristics of the presentation information. Hereinafter, we will judge whether or not the trigger processing is required for the attribute of the subscription user 2b.

 When the processing trigger condition is determined based on the status information of the subscribing user 2b, the S-CSCF1 needs to process the presentation information to be sent to the subscribing user 2b, for example, when the status information of the subscribing user 2b is busy, for example, When the subscribing user 2b is busy, the presentation information sent to the subscribing user 2b is discarded.

In another embodiment, when the processing trigger condition is determined based on the load of the subscribing user 2b, for example, determining whether the subscribing user 2b is overloaded, if the subscribing user 2b is overloaded, the S-CSCF1 needs to be sent to the subscribing user 2b. The presence information is processed, for example, if the subscribing user 2b is overloaded, the S-CSCF1 discards the presence information sent to the subscribing user 2b, or filters the presence information sent to the subscribing user 2b, for example, the presence information is forwarded to the subscribing user 2b. The frequency is reduced, for example, the presence information that arrives at the S-CSCF1 at the hour and half points is forwarded to the subscribing user 2b, and the presence information that arrives at the S-CSCF1 at other times is discarded to ensure that the traffic received by the subscribing user 2b is One Within the range.

 In another embodiment, when the processing trigger condition is based on the capability of the terminal of the subscribing user 2b, for example, the processing capability supported by the subscribing user 2b includes, but is not limited to, the CPU used by the subscribing user 2b, the memory, and the network connection. Situation, modulation coding method, software processing capability, supported language, display resolution, etc. For example, if the presentation information provided by the presentation information source 2a is Japanese, and the language supported by the subscription user 2b is Chinese and English, the S-CSCF1 needs to process the presentation information of the Japanese language to be sent to the subscription user 2b. It is converted to Chinese information. For another example, in another embodiment, the user terminal used by the subscribing user 2b cannot support the MMS, and when the S-CSCF1 obtains the presence information from the MMS provided by the presence information source 2a, the S-CSCF1 performs corresponding For example, the format information of the MMS is converted into a format of the short message, and then provided to the subscribing user 2b, specifically, first sent to the network device P-CSCF, and then provided by the P-CSCF to the subscribing user 2b, or the presentation is performed. Information is discarded.

 In another embodiment, when the processing trigger condition is based on the location information of the subscribing user, for example, the subscribing user 2b wants to display the presence information only when at home, and does not wish to display the presentation information at the office or on the go, the subscriber can be judged. The location information, if the subscriber 2b is at home, provides the presence information to the subscriber 2b, otherwise, if the subscriber 2b is in the office, the presentation information to be sent to the subscriber 2b is processed, for example, the presentation is discarded. information.

 In another embodiment, when the processing trigger condition is based on the personalized setting of the subscribing user 2b, for example, determining whether the subscribing user 2b needs to reduce the traffic on the user side, if the subscribing user 2b needs to reduce the traffic on the user side, the S-CSCF1 needs The presentation information to be sent to the subscribing user 2b is processed, for example, the presence information is discarded.

 Of course, the S-CSCF 1 sends the presence information to the subscribing user 2b. The presence information may be first provided to the P-CSCF through a NOTIFY message in step S221, and then the P-CSCF passes the announcement in step S222. NOTIFY) The message is provided to the subscribing user 2b.

Then, in step S23, the subscribing user 2b sends a 200 (OK) message to the P-CSCF for feeding back to the S-CSCF1 that the subscribing user 2b has received the presence information; then, in step S24, the P-CSCF goes to the S again. -CSCF1 sends a 200 (OK) message; then, In step S25, the S-CSCF 1 transmits a 200 (OK) message to the presence server 3. It should be noted that, if in step S220, if the processing of the presence information by the S-CSCF1 is to discard the presence information, step S23 and step S24 will be skipped, but step S25 remains, because the S-CSCF1 pair The process of presenting information is transparent to the network in which the present information source 2a is located, and the presence information source 2a does not need to perceive that the subscribing user has not received the presence information from the presence information source 2a.

 Then, in step SB, the presentation server 3 feeds back a 200 ( O ) message to the presentation information source 2a. The dotted arrow of SB in the figure indicates that the P-CSCF and S-CSCF between the presentation information source 2a and the subscribing user 2b are omitted.

 Figure 3 shows a block diagram of a device in accordance with an embodiment of the present invention. The device 10 includes an acquisition device 100, a determination device 101, and a processing device 102.

 First, the acquisition means 100 acquires the processing trigger condition configured by the subscribing user 2b, and acquires the presentation information issued by the presentation information source 2a from the presentation server 3. The processing trigger condition is used to determine whether the S-CSCF1 needs to process the presentation information to be sent to the subscribing user 2b, and the obtaining apparatus 100 further acquires the presentation information to be sent to the subscribing user.

 For example, the subscribing user 2b may process the triggering condition based on a user interface setting such as a webpage, a touch screen, or the like. The triggering condition may be determining whether the S-CSCF1 needs to be triggered to process the presence information according to an attribute of the presence information from the presentation information source, or may be based on the subscription. The attribute of the user 2b determines whether it is necessary to trigger the S-CSCF1 to process the presence information.

 A. Any one of the attributes based on the attributes of the presence information from the presentation source:

 - judging whether the size of the presentation information to be sent to the subscribing user 2b exceeds a predetermined value, and if the size of the presentation information to be transmitted to the subscribing user 2b exceeds a predetermined value, the presentation information to be sent to the subscribing user 2b needs to be processed;

 - judging whether the presentation information to be sent to the subscribing user 2b includes the predetermined content, and if the presentation information to be transmitted to the subscribing user 2b includes the predetermined content, the presentation information to be transmitted to the subscribing user 2b needs to be processed;

- judging that the presentation server 3 sends the presentation from the presence information source 2a to the subscription user 2b Whether the transmission frequency of the current information exceeds a predetermined frequency; if the transmission frequency of the presentation information sent from the presence information source 2a by the presence server 2b to the subscribing user 2b exceeds a predetermined frequency, the presentation information to be sent to the subscribing user 2b needs to be performed. deal with;

 - judging whether the time at which the presentation server 3 transmits the presence information to the subscribing user 2b belongs to a predetermined time period; for example, the subscribing user 2b may set a predetermined time period from 11:00 pm to 6:00 pm, which is undesired to receive the presence information, if S The time at which the presentation information received by the CSCF1 falls within the predetermined time period, the presentation information to be sent to the subscribing user 2b needs to be processed.

 B. Determine whether trigger processing is required based on the attributes of the subscribing user 2b

 - determining based on the status information of the subscribing user 2b, for example, when the status information of the subscribing user 2b is busy or leaving or in a conference, the presentation information to be sent to the subscription user 2b needs to be processed;

 - judging based on the load of the subscribing user 2b, for example, judging whether the subscribing user 2b is overloaded, and if the subscribing user 2b is overloaded, the presentation information to be sent to the subscribing user 2b needs to be processed;

 - Judging based on the capability of the subscriber of the subscriber 2b, for example, the processing capability supported by the subscriber 2b, including but not limited to the CPU, memory, network connection, modulation and coding mode, software processing capability, and support used by the subscriber 2b Language, display resolution, etc. For example, if the presentation information provided by the presentation information source is Japanese, and the language supported by the subscription user 2b is Chinese and English, the presentation information to be sent to the subscription user 2b needs to be processed, or

 - based on the location information of the subscribing user, for example, the subscribing user 2b wants to display the presence information only when he is at home, and does not want to display the presence information when he is at the office or on the go, and can determine the location information of the subscribing user, if the subscribing user 2b is at home, Providing the presence information to the subscribing user 2b. Otherwise, if the subscribing user 2b is in the office, the presentation information to be sent to the subscribing user 2b is processed, for example, discarding the presentation message<3⁄4·,

- Based on the personalized setting of the subscriber 2b, for example, whether the subscriber 2b needs to reduce the traffic on the user side, and if the subscriber 2b needs to reduce the traffic on the subscriber side, it is determined that the presentation information to be sent to the subscription advertisement 2b needs to be processed. . These processing trigger conditions may be stored in an existing Home Subscriber Server (HSS). Of course, they may also be stored in a dedicated server for use by the service logic of the judging device 101.

 Then, the judging means 101 judges whether or not the processing trigger condition configured by the subscribing user 2b is satisfied based on the presentation information to be transmitted to the subscribing user.

 First, the processing trigger condition configured by the subscribing user 2b is an attribute judgment based on the presence information of the presentation information source as an example.

 For example, the triggering condition is that the determining means 101 determines whether the size of the presence information to be transmitted to the subscribing user 2b exceeds a predetermined value. If the size of the presentation information to be transmitted to the subscribing user 2b exceeds a predetermined value, the judging means 101 judges that it is necessary to send the message. The presentation information of the subscribing user 2b is processed, for example, the processing device 102 may discard the presence information; otherwise, the processing device 102 directly provides the presence information to be sent to the subscribing user 2b to the subscribing user 2b through the NOTIFY message;

 For another example, the judging device 101 may further determine whether the presentation information to be sent to the subscribing user 2b includes predetermined content, which may be some sensitive words set, or keywords, in the server of the S-CSCF1, for example In the HSS, a word such as "invoice", "smuggling", "open house" and other words are used as sensitive words. When the above sensitive words appear, for example, the processing device 102 needs to send the words to be sent to Subscribing to the presentation information of the user 2b, for example, discarding the presence information containing the sensitive words; or masking the keywords in the message, for example, the words "invoice", "smuggling", "opening of the villa" After the deletion, the processed message is provided to the subscribing user 2b through the NOTIFY message; otherwise, if the S-CSCF1 determines that the presentation information sent to the subscribing user 2b does not include the predetermined content, the processing device 102 will be sent to the subscribing user. The presentation information of 2b is provided directly to the subscribing user 2b through the NOTIFY message.

In another specific embodiment, the judging device 101 can further determine whether the sending frequency of the presence information sent from the presence information source 2a by the presence server 2b to the subscribing user 2b exceeds a predetermined frequency; if the presence server 3 sends the notification from the subscribing user 2b The sending frequency of the presentation information of the presentation information source 2a exceeds a predetermined frequency, and the processing device 102 needs to process the presentation information to be sent to the subscribing user 2b, and the processing may be When the judging device 101 finds that the transmission of the presence information from the presentation information source 2a exceeds a predetermined frequency, for example, the presentation information from the presentation information source 2a exceeds a predetermined threshold within a fixed time interval, the processing device 102 according to the pre-configuration And discarding the presentation information received by the processing device 102 to be sent to the subscribing user 2b. Of course, in another embodiment, the processing device 102 may also exceed the fixed information source 2a after the fixed time interval. The presence information is transmitted at a predetermined reduced frequency, for example, the presence information from the presence information source 2a is sent to the subscribing user 2b every 1 hour, and the presence information received from the presentation information source 2a at other times is discarded.

 In another specific embodiment, the determining means 101 can also determine whether the time at which the presence server 3 sends the presence information to the subscribing user 2b belongs to a predetermined time period; for example, when the trigger condition is the subscribing user 2b, 11:00 to 6 in the evening When the point is set to a predetermined time period in which it is not desired to receive the presence information, if the time at which the presentation information received by the capture device 100 falls within the predetermined time period, the processing device 102 needs to present the presentation to be sent to the subscription user 2b. Information is processed. For example, the processing device 102 discards the presence information to be sent to the subscribing user 2b, for example, at 2 am.

 In the above, the presentation information from the presentation information source 2a is controlled and processed for the content of the presentation information and the transmission characteristics of the presentation information. Hereinafter, we will judge whether or not the trigger processing is required for the attribute of the subscription user 2b.

 When the processing trigger condition is based on the status information of the subscribing user 2b, the processing device 102 needs to process the presentation information to be sent to the subscribing user 2b, for example, when the status information of the subscribing user 2b is busy, for example, When the subscribing user 2b is busy, the presence information sent to the subscribing user 2b is discarded.

In another embodiment, when the processing trigger condition is determined based on the load of the subscribing user 2b, for example, determining whether the subscribing user 2b is overloaded, if the subscribing user 2b is overloaded, the processing device 102 needs to be sent to the subscribing user 2b. The presence information is processed, for example, if the subscribing user 2b is overloaded, the processing device 102 discards the presence information sent to the subscribing user 2b, or filters the presence information sent to the subscribing user 2b, for example, will forward the presentation to the subscribing user 2b The frequency of the information is reduced, for example, the presence information that arrives at the S-CSCF1 at the hour and half is forwarded to the subscribing user 2b, and will be The presence information of the S-CSCF1 is discarded at other times to ensure that the traffic received by the subscriber 2b is within a certain range.

 In another embodiment, when the processing trigger condition is based on the capability of the terminal of the subscribing user 2b, for example, the processing capability supported by the subscribing user 2b includes, but is not limited to, the CPU used by the subscribing user 2b, the memory, and the network connection. Situation, modulation coding method, software processing capability, supported language, display resolution, etc. For example, if the presentation information provided by the presentation information source 2a is Japanese, and the language supported by the subscription user 2b is Chinese and English, the processing device 102 needs to process the presentation information of the Japanese language to be sent to the subscription user 2b. It is converted to Chinese information. For another example, in another embodiment, the user terminal used by the subscribing user 2b cannot support the MMS, and when the obtaining device 100 acquires the presence information from the MMS provided by the presence information source 2a, the processing device 102 performs corresponding For example, the format information of the MMS is converted into a format of the short message, and then provided to the subscribing user 2b, specifically, first sent to the network device P-CSCF, or the presence information is discarded.

 In another embodiment, when the processing trigger condition is based on the location information of the subscribing user, for example, the subscribing user 2b wishes to display the presentation information when only at home, and does not wish to display the presentation information at the office or when going out, the judging device 101 The location information of the subscribing user can be judged. If the subscribing user 2b is at home, the processing device 102 provides the presence information to the subscribing user 2b. Otherwise, if the subscribing user 2b is in the office, the processing device 102 sends the presentation to the subscribing user 2b. The information is processed, for example, by discarding the presence information.

 In another embodiment, when the processing trigger condition is based on the personalized setting of the subscribing user 2b, for example, the judging device 101 determines whether the subscribing user 2b needs to reduce the traffic on the user side, and if the subscribing user 2b needs to reduce the user side traffic, the processing is processed. The device 102 needs to process the presence information to be sent to the subscribing user 2b, for example, discarding the presence information.

 Of course, when the S-CSCF1 sends the presence information to the subscribing user 2b, the presentation information may be first provided to the P-CSCF, and then provided by the P-CSCF to the subscribing user 2b.

Then, the subscribing user 2b sends a 200 (OK) message to the P-CSCF for feeding back to the S-CSCF1 that the subscribing user 2b has received the presence information; then, the P-CSCF1 is redirected The S-CSCF1 sends a 200 (OK) message; then, the S-CSCF1 sends a 200 (OK) message to the application server that presents the information source 2a, notably, if the processing of the presence information by the processing device 102 is the presentation information If the packet is discarded, the S-CSCF1 directly sends a 200 (OK) message to the presence server 3, because the process of the presence information of the S-CSCF1 is transparent to the network where the information source 2a is present, and the presence source does not need to perceive the subscriber. The presence information from the presentation information source 2a is not received.

 The present invention is described by taking IMS as an example. Those skilled in the art can understand that the present invention is not limited to an IMS network, and can also be applied to other networks supporting a presence service, such as the Internet, etc., and the SIP protocol in each step is changed to the Internet.
