In the existing communication technology, different user profile branches is on the different servers, is present on the presence server as presentation information, and presentation information comprises user's online information, network carrying information, client device application power information or the like; Position (Location) information has been pointed out user's present located geographical position, is present on the location server.If we to obtain to be positioned near some markets, state is online user list, at this moment just need just can judge and select according to current presentation information of user and their geographical location information.Utilize present CBUS (user based on condition selects) technology, the requestor can be with to the geographical position, the requirement of information or condition such as presenting delivers to the user and selects server, the user selects server to be connected with various status information server, for example obtain presentation information to presence server, obtain geographical location information to location server, and carry out these results analysis integrated, be sent to the requestor with satisfying the user URI that the requestor sends condition, thereby no longer need the requestor directly to come into contacts with, only need submit to the user to demand and select server to get final product with various servers.
The substance of CBUS is according to some alternative conditions, and the various information that the requestor can provide are carried out user's selection, thereby determines whether this user is exactly the object that the requestor will seek.These users' range of choice can be one group of user that requestor oneself sets, also specified scope not, and at this moment the user selects server must use search operation to seek all users that satisfy condition (being user terminal).The user selects server when carrying out user's selection, both can just carry out the selection of a snapshot formula according to condition and scope, the also monitoring that can continue to user's information, be not completely cured and carry out user's selection again according to the user profile of upgrading, thereby the selection result that obtains upgrading, this monitoring can be until condition satisfies, and also can be in a specific time.
The function that the user selects can only be applied to obtain qualified user profile, is mainly used at these users and initiates a certain communication service but obtain qualified user profile, as Push to talk over Cellular (PoC, Pushto talk Over Celluar) business.PoC service is the business of group's intercommunication, the user asks the PoC session of communication server initiation at a group, but because some user's position causes the content of session is lost interest in (such as the interchange of flash sale, if the user is in other city, these conversations are just nonsensical to him), therefore also need not to initiate session with these users, at this moment the user can select server requests to select suitable user to the user, after obtaining selection result, initiate again and these sessions between the user as a result.Its roughly flow process comprise as shown in Figure 1:
1, the user list that communication customer end will initiation session sends to CBUS client (selection client);
2, the CBUS client sends to CBUS server (selection server) with the alternative condition of user list and user's input;
3, the CBUS server is finished the selection to the user, and with selection result, promptly qualified user list returns to the CBUS client;
4, the CBUS client sends to communication customer end with end user's tabulation;
5, the new user list of communication customer end utilization is set up request to communication server initiation session;
6, the communication server returns processing of request information is set up in session.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art: in above-mentioned scene, communication customer end and selection client are in the same terminal, the communication server and selection server are in network side, then between terminal and network for finish this communicate by letter carried out four times mutual, taken a large amount of interface-free resources, this has not only influenced the speed that the user initiates to serve, and also may bring extra communication cost to the user.
Though the CBUS client application can suitably be reduced taking of interface-free resources on the communication server, in this case, the communication server obtains session from user terminal and sets up request, the list of targeted subscribers that wherein comprises session, the communication server passes through the CBUS client to the user selection operation of CBUS server requests at this user list and alternative condition, the CBUS server returns to the communication server with the result that the user selects, the communication server initiate again with selection result in the user set up session.But this method need be revised communication protocol to carry user's alternative condition parameter.This must influence the use and the compatibility of existing communication technology.

Step 204, the communication server after finishing to the processing of communication information to communication customer end return result.
What need supplementary notes is, owing in step 203, will utilize the communication target user in user's selection result replacement communication information, therefore the user who sends in step 202 terminal selects in the request message, the target or the position of generally wanting the designated user selection result to replace.
In addition, the communication server not necessarily directly sends to communication customer end from the communication server to the operating result that communication customer end returns, and it also may be to select server, user to select client to be transmitted to communication customer end by the user.
Send to the user in step 202 terminal and select to attach original communication information itself in the communication information content of server, also can attach the parameter of forming this communication information.If subsidiary is the parameter of forming this communication information, then can selects server to form communication information and send to the communication server by the user.
As can be known above-mentioned, the function of the existing CBUS of embodiment of the invention utilization realizes that terminal is set up request message with communication session and the user selects message to send to network side simultaneously, and network can once be finished the work that the user selects, session is set up.
Under existing former communication mode, communication customer end can send Session initiation Protocol and invite (SIP INVITE) message to give the communication server.In the present embodiment, terminal sends calling transfer (REFER) message and selects server to the user, selects server to finish the selection of communication target by the user, and transmits communication information subsidiary in the REFER message to the communication server.Figure 3 shows that the renewal session object of present embodiment 1 and set up the idiographic flow of conversation, among Fig. 3:
(1) message 301 is a REFER message, is the calling transfer message that terminal selects server to send to the user.The user selects server can replace terminal to send a communication information (as INVITE) according to this message and gives the communication server.
In the message body of this REFER message, having comprised for the user selects server to carry out user's range of choice of user's selection operation and two parameters of user's alternative condition (if user's range of choice parameter is not provided, the scope that the expression user selects is all users), comprised that also the user selects the content of server generation terminal to the communication information (session establishment information) of communication server transmission.For example, if the terminal use will send a session and set up request message to the PoC server, be positioned at Pekinese and online user's communications in the middle of request foundation and communication target user PoC-UserB, PoC-UserC and the PoC-UserD, then user's range of choice of REFER message is: PoC-UserB, PoC-UserC and PoC-UserD; User's alternative condition is: the position is in Beijing and online.Communication information subsidiary in the REFER message is set up request message for request and the session that user PoC-UserB, PoC-UserC and PoC-UserD set up session.
In REFER message, also carried the type (as application/CBUS-operation+xml, comprise one section xml code in the expression message body, be used for user's selection operation) of beared information, the user selects server can discern and handle the data of the type, i.e. content in the message body.And, generally also to inform the deposit position of user's selection result in the REFER message, can indicate the result that the user is selected to be substituted under the path in the message body, for example indicate the position that user's selection result is substituted into communication information (as INVITE) Central Plains user list.
(2) message 302 (INVITE) is that request message is set up in the session that the user selects server to send to the communication server.
After the user selects server to select qualified user, described qualified user as the communication target user, is generated INVITE according to described communication information, be sent to the communication server.
Particularly, after the user selects server to receive this REFER message, know that from the beared information type user's selection is carried out in the communication customer end request of terminal, from this message body, obtain and carry out user scope tabulation and the alternative condition that the user selects.Obtain qualified user list according to user scope and alternative condition, suppose that PoC-UserC and PoC-UserD are eligible.Then the user selects server to extract INVITE from calling transfer message, the user list of selection result is substituted into the position of original subscriber's tabulation, and sends this INVITE to the communication server.
The message content basically identical that encapsulates in the INVITE in this INVITE and the existing communication mode, the content of unique change is the user list that comprises in the message body, the user list in the present embodiment is the user list that the user selects server to select.According to present embodiment, the session that communication customer end sends to the communication server is set up request message and is selected the processing of server through the user, only and the user wish to set up session between the user of initiation session.
(3) message 303～310th, the normal interaction message behind the INVITE, it is the subsequent message in the INVITE normal process process, according to the description of RFC 3515 agreements, the answer message corresponding with REFER is NOTIFY, and is the 200OK response message to the answer message of NOTIFY.The response message of the INVITE in the message 303,306 will be encapsulated in respectively in the NOTIFY 304,307.Message 305,308 is respectively the answer to message 304,307.The session of message 309,310 expression INVITE requests is set up and is finished.Message 309 utilizes REFER message to select server to send to the communication server by the user ACK message equally.
After session is set up, will set up between communication customer end and the communication server and communicate by letter normally.
Method by present embodiment, terminal can be set up communication session request message and user and select message to send to network side simultaneously, network can once be finished the work that the user selects, session is set up, therefore the interactive information of terminal and network side only needs 1 back and forth, saved interface-free resources greatly, and to the communication server without any influence.
In the present embodiment, described user selects server as shown in Figure 7, comprising:

Embodiment 3
Present embodiment is substantially the same manner as Example 1, and difference is: the subsidiary communication information itself of REFER message among the embodiment 1, and in the present embodiment REFER message subsidiary be the parameter of this communication information of composition.
In this embodiment, terminal directly is encapsulated in the parameter of some communication informations in the REFER message, after the user selects server to receive this REFER message, finish user's selection operation, and generate a communication information at the communication server according to wherein communication information parameter, the communication server replies to terminal with response message after receiving this message and processing.
The parameter of described communication information can comprise: initiator's sign, communication information recipient sign, communication information server identification, communication information content and user's range of choice of the field of communication information, the order of communication information, communication information, user's alternative condition, and the deposit position of user's selection result.
For example, the particular content of each parameter is:
The field of communication information: PoC;
The order of communication information: SIP INVITE;
Initiator's sign of communication information: Alice＜sip:alice@atlanta.com 〉;
Communication information recipient sign: PoCConferenceFactoryURI.networkA.net;
Communication information server identification: ServerA＜sip:ServerA.networkA.net 〉;
Communication information content: the content in the INVITE among the SIP BODY;
User's range of choice: PoC-UserB, PoC-UserC and PoC-UserD;
User's alternative condition: in Beijing, and state is online;
The deposit position of user's selection result: Message/Body/resource-lists/list (position of INVITE Central Plains list of targeted subscribers).
Finish after the user selects when the user selects server, according to the deposit position of user's selection result the result that the user selects is substituted in the Content of Communication as the targeted customer, its method is identical with embodiment 1; And generate corresponding communication information, and this message is sent to the communication server according to the field of communication information.
It is pointed out that target when communication is exactly group during user ID, promptly the scope selected of user is exactly the recipient of communication information when identifying, and parameter " scope that the user selects " and " recipient of communication information identifies " can be merged into a parameter.
Method by present embodiment, terminal can be set up communication session request message and user and select message to send to network side simultaneously, network can once be finished the work that the user selects, session is set up, therefore the interactive information of terminal and network side only needs 1 back and forth, saved interface-free resources greatly, and to the communication server without any influence.
Embodiment 4
Under the scene of the various embodiments described above, the user selects server also to need the result who carries out to terminal return.
When the user selects server to carry out user's selection operation, the user selects server can return the result of user's selection operation to terminal, but because the request message of terminal is the message of calling transfer class, the user selects server not only will finish user's selection operation, also needs the operation of executive communication forwards.Particularly when the user selects the server execution to make mistakes, special processing procedure is arranged.Following two kinds of processing modes are for example arranged:
Mode one (shown in Fig. 5 a):
Step 503, the user selects server to return the user to terminal and selects error messages (as sip message 401,402 or 501, but be not limited to this, can represent error messages with 4xx or 5xx at this), and informs that communication information sends.
Under this mode, as shown in Figure 9, the user selects server except that having receiving element 701, user selection unit 702 and communication session request transmitting element 703, also has the first fault processing unit 704 and the first errored response unit 705:
The described first fault processing unit 704 is used for when execution user selection operation is made mistakes, the dropped users selection operation, and the targeted customer who carries in selecting to ask with the user is the communication target user, generates the session request of setting up according to described session establishment information and is sent to the communication server;
