in step 205, if the PS determines that a member is in the login state, the PS returns the presence information of the member to the RLS.
And the PS judges the states of all the members, and if a certain member is judged to be in the login state, the PS returns the presentation information of the member to the RLS through the core network.
In step 206, the PS continues to determine the next member status.
And the PS judges the states of all the members, and if a certain member is judged to be in the login state, the PS returns the presentation information of the member to the RLS through the core network and continues to judge the state of the next member.
Step 207, if the PS determines that the member is in the non-login state, immediately ending the subscription session for the member presence information established with the RLS.
Ending the subscription session established with the RLS for the member presence information may be achieved by setting expires to 0 in the NOTIFY of the notification. Generally, The subscription Session between The RLS and The PS for The member Presence information follows an expire mechanism of Session Initiation Protocol (SIP) signaling, and The subscription Session is maintained until The expire time, as described in Internet Engineering Task Force (IETF) RFC 3265, RFC 3856, and RFC 4662 for Presence subscription. In the step, the time of the expire is set to 0, so that when the PS determines that the member is in the non-login state, the time of the expire is set to 0, and the instant ending of the subscription session with the RLS for the member to present the information is realized.
Optionally, if the PS determines that the member is in the non-login state, the PS automatically ends the subscription session for the presence information of the member, which is established with the RLS. By automatically ending the subscription session for the member presence information established between the terminal and the RLS, the time for passively ending the subscription session for the member presence information established between the terminal and the RLS according to the trigger is saved, and the instant ending of the subscription session for the member presence information established between the terminal and the RLS is realized. As described above, the subscription Session for the member presence information between the RLS and the PS generally follows an expire mechanism of Session Initiation Protocol (SIP) signaling, and the subscription Session is maintained until the expire time, that is, the expire time triggers an instruction to end the subscription Session. However, the embodiment of the present invention may not follow the ending mechanism, that is, once the PS determines that the member is in the non-login state, the PS automatically ends the subscription session with the RLS for the presence information of the member in the non-login state.
It will be appreciated that this may be achieved in other ways as will be appreciated by those skilled in the art.
Further, the method may further include the following operations: if the PS determines that a certain member is in a non-login state, the PS stores a subscription session record established between the PS and the RLS for the member presence information. And after learning that the member in the non-login state logs in, informing the RLS to reinitiate a session request for subscribing the presence information of the member in the non-login state.
In step 208, the RLS summarizes the member presence information returned by the PS into a member list.
In step 209, the RLS returns the summarized member list to the end user.
The RLS returns the summarized member list to the end user through the core network.
Further, after the member logs in, the PS determines whether a subscription session record for the member presence information is stored. If the PS stores the subscription session record of the member presence information, the PS informs the RLS of the login information of the member through the core network. After receiving the message, the RLS re-initiates a session request for subscribing the member presence information to the PS through the core network. After receiving the session request, the PS carries out subscription session with the RLS and sends the member presentation information to the RLS through the core network. Optionally, the specific method may be implemented by the following program:
