Fig. 2 be under non-roaming condition self grouping of terminal group calling system flow chart, the non-roaming situation described in this flow chart specifically refers in self-built group that all members belong to same ownership place and all at ownership place, visited place is ownership place, its step is as follows:
Step 201: calling terminal is initiated self-built group at ownership place by message registration or phone directory and risen to call for and ask to ownership place base station sub-system, and ownership place base station sub-system rises to call for to ask by self-built group passes to ownership place dispatch server;
Terminal rises while exhaling by phone directory, rise to call in asking and carry conversation number list, conversation number list comprises all called numbers, conversation number list starts with two spcial characters, thereby distinguish, whether carry interim group number, between each number, with this spcial character interval, conversation number list finishes with another kind of spcial character;
Step 202: ownership place dispatch server receive self-built group rise and call for and ask after, create this and call out relevant list item, as group attribute table, user attribute table, member property table etc.; Recorded the various information of calling in asking, as information such as calling terminal (IMSI, ESN, positional information), self-built group of interim group number, call model, called number lists; Start information about firms and upgrade timer; To ownership place schedule register, send temporary group calling authentication request;
Step 203: ownership place schedule register is carried out authentication, distributed interim GID (group identification number) caller, GID is kept in information about firms table, authentication responses message is returned to ownership place dispatch server, in authentication responses message, carry GID and the calling user information of interim distribution;
Step 204: ownership place dispatch server is received after temporary group calling authentication responses message, records group and caller information, rises to call for to ask according to self-built group and judges whether this is called out is initiatively to lag and add.Its judgment principle is as follows:
If self-built group is risen to call in asking and do not carry self-built group of interim group number, for non-active lagging, add;
If carry self-built group of interim group number in call message, traversal caller information about firms table, according to the group's distribution process table in the GID location ownership place dispatch server in information about firms table, interim group number in coupling group distribution process table and self-built group of interim group number in call message, after if caller information about firms table has traveled through, while matching the interim group number consistent with self-built group of interim group number in call message, for initiatively lagging and add; Otherwise add for non-active lagging;
Judge this call out for non-active lag add after, ownership place dispatch server generates interim group number according to GID and timestamp, and preserves interim group number, by ownership place base station sub-system, sends paging request to calling terminal;
Step 205: what ownership place dispatch server was initiated terminal called to ownership place schedule register adds calling authorization request temporarily;
Step 206: calling terminal access calling, loopback pages reply, and the ownership place base station sub-system message that will page reply is passed to ownership place dispatch server;
Step 207: ownership place schedule register is received temporarily adding after calling authorization request of called subscriber, to the called authentication of carrying out, to ownership place dispatch server, carries called user information by authentication responses loopback in authentication responses;
Step 208: ownership place dispatch server records called party information, sends paging request to ownership place base station sub-system, and ownership place base station sub-system is passed to terminal called by paging request;
Step 209: terminal called access calling, loopback pages reply, and the ownership place base station sub-system message that will page reply is passed to ownership place dispatch server;
Step 210: ownership place dispatch server is received paging reply after message of calling and called, according to call setup condition (except caller access, must have a called access calling at least), judge this and called out successfully foundation, to calling terminal, authorize right of speech.Ownership place base station sub-system is passed to calling terminal by authorization messages;
Step 211: calling terminal loopback authorization response, ownership place base station sub-system is passed to ownership place dispatch server by authorization response;
Step 212: ownership place dispatch server receives after the authorization response message of calling terminal, the terminal called having accessed in giving self-built group sends right of speech prompting, and ownership place base station sub-system is passed to terminal called by right of speech prompting message;
Step 213: ownership place dispatch server is judged in self-built group after all called authentications finish, the terminal called that in giving self-built group, success has accessed sends message registration, and retransmission timer is set, in message registration, carry the list of numbers (being all member's numbers in interim group number and this calling) of this call, list of numbers starts with spcial character, and between each number with this spcial character interval, and finish (generally, first number is interim group number) with another kind of spcial character.Ownership place base station sub-system is passed to terminal called by message registration;
Illustrate: in all called authentications, finish the terminal called accessing after this time point, ownership place dispatch server sends message registration to separately this terminal called; The message registration of calling terminal is preserved by calling terminal oneself, without ownership place dispatch server, sends to calling terminal;
Step 214: terminal called loopback message registration is replied, ownership place base station sub-system is replied that message registration pass to ownership place dispatch server;
Illustrate: if retransmission timer then after, ownership place dispatch server does not receive that the message registration of terminal replys, and continues execution step 213;
Step 215: information about firms upgrade timer then after, ownership place dispatch server sends information about firms updating message to all calling and called terminals that accessed, comprising number of members, member's number, member Name, member condition.Ownership place base station sub-system is passed to calling and called terminal by information about firms updating message.If sent after information about firms updating message, there is member condition to change, ownership place dispatch server continues again to send information about firms updating message to all online terminals.
In addition, after this end of calling, if wherein a terminal called has initiated to exhale, according to message registration, rise while exhaling, rise to call in asking and carry conversation number list, conversation number list comprise last time interim group number and all called numbers (generally, interim group number is placed in the first place of conversation number list), conversation number list starts with spcial character, and between each number, with this spcial character interval, conversation number list finishes with another kind of spcial character;
Fig. 3 be under non-roaming condition terminal initiatively lag add self-built group calling system flow chart, the non-roaming situation described in this flow chart specifically refers in self-built group that all members belong to same ownership place and all at ownership place, visited place is ownership place, its step is as follows:
Step 301: terminal is initiated self-built group by message registration to ownership place base station sub-system at ownership place and risen to call for and ask, and ownership place base station sub-system rises to call for to ask by self-built group passes to ownership place dispatch server; Self-built group is risen to call for and carries interim group number and all called numbers in asking (generally, interim group number is placed in the first place of conversation number list), conversation number list starts with spcial character, identify the beginning of this conversation number list, between each number, with this spcial character interval, conversation number list finishes with another kind of spcial character;
Step 302: ownership place dispatch server receive self-built group rise and call for and ask after, create this and call out relevant list item, as group attribute table, user attribute table, member property table etc.; Recorded the various information of calling in asking, as information such as calling terminal (IMSI, ESN, positional information), self-built group of interim group number, call model, called number lists; Start information about firms and upgrade timer; To ownership place schedule register, send temporary group calling authentication request;
Step 303: ownership place schedule register is carried out authentication, distributed interim GID caller, and temporary group calling authentication responses message is returned to ownership place dispatch server, carries GID and the calling user information of interim distribution in temporary group calling authentication responses;
Step 304: ownership place dispatch service is received after temporary group calling authentication responses, record group and caller information, according to self-built group of interim group number in call message, after judging this and calling out and to add for initiatively lagging, ownership place dispatch server is deleted and is worked the related resource of exhaling foundation for this, as group attribute table, the calling terminal that giving lags adds sends calling terminal paging request;
Step 305, calling terminal access calling, loopback pages reply to ownership place base station sub-system, and the ownership place base station sub-system message that will page reply is passed to ownership place dispatch server;
Step 306: ownership place dispatch server is received after paging reply of calling terminal, authorize right of speech to ownership place base station sub-system or send right of speech prompting and (specifically according to whether there being member to take right of speech in current group, determine, there is member to take right of speech, give entrant's right of speech prompting that lags; Otherwise, authorize right of speech to the entrant that lags); In the terminal adding that lags, had message registration, thus ownership place dispatch server without again sending message registration to terminal, if what send is right of speech prompting message, skips steps 307, directly perform step 308; Ownership place base station sub-system sends authorization messages or right of speech prompting message to calling terminal;
Step 307: calling terminal loopback authorization response is to ownership place base station sub-system, and ownership place base station sub-system is passed to ownership place dispatch server by authorization response;
Step 308: now have member condition to change in self-built group, ownership place dispatch server sends information about firms updating message to ownership place base station sub-system, and ownership place base station sub-system sends information about firms updating message in self-built group all online terminals.
Fig. 4 and Fig. 5 be under roaming condition self grouping of terminal group calling system flow chart, roaming condition described in this flow chart specifically refer in self-built group caller in roaming place, part is called with caller in same visited place and to belong to same ownership place, part called in another visited place and belong to Another Place To Fall ground with caller, its step is as follows:
Step 401: calling terminal has been initiated to call for by phone directory in visited place and asked;
Illustrate: terminal rises while exhaling by phone directory, rise to call in asking and carry all called numbers, conversation number list starts with two spcial characters, thereby distinguish, whether carries interim group number, between each number, with this spcial character interval, conversation number list finishes with another kind of spcial character;
Step 402: caller visited place dispatch server creates this and calls out relevant list item, as group attribute table, user attribute table, member property table etc. after having received and having called for and ask; Recorded the various information of calling in asking, as information such as calling terminal (IMSI, ESN, positional information), call model, called number lists; Start information about firms and upgrade timer; To caller visited place schedule register, send temporary group calling authentication request, visited place schedule register passes through master home ground schedule register by temporary group calling authentication request;
Step 403: master home ground schedule register is carried out authentication, distributed interim GID caller, and by the loopback of authentication responses message to caller visited place schedule register, in authentication responses message, carry GID and the calling user information of interim distribution, caller visited place schedule register passes through caller visited place dispatch server by authentication responses message;
Step 404: caller visited place dispatch server is received after temporary group calling authentication responses message, records group and caller information, according to self-built group of interim group number in call message, judges whether this is called out is initiatively to lag and add, and its judgment principle is as follows:
If do not carry self-built group of interim group number in call message, add for non-active lagging;
If carry self-built group of interim group number in call message, traversal caller information about firms table, according to the GID location group distribution process table in information about firms table, interim group number in coupling group distribution process table and self-built group of interim group number in call message, after if caller information about firms table has traveled through, while matching the interim group number consistent with self-built group of interim group number in call message, for initiatively lagging and add; Otherwise add for non-active lagging;
Judge this call out for non-active lag add after, caller visited place dispatch server generates interim group number according to GID and timestamp, to calling terminal, sends paging request.
Step 405: caller visited place dispatch server stops group calling authentication, that to caller visited place schedule register, initiates called subscriber adds calling authorization request temporarily, and caller visited place schedule register passes through master home ground schedule register by authentication request; Illustrate: in this step, ask the terminal called of authentication and calling terminal to belong to same ownership place;
Step 406: what caller visited place dispatch server was initiated called subscriber to caller visited place schedule register adds calling authorization request temporarily.Caller visited place schedule register passes through dialed field schedule register by authentication request; Illustrate: in this step, ask the terminal called of authentication and calling terminal not to belong to same ownership place, belong to another ownership place;
Step 407: calling terminal access calling, pages reply to the dispatch server loopback of caller visited place;
Step 408: master home ground schedule register is received temporarily adding after calling authorization request of called subscriber, to the called authentication of carrying out, and by authentication responses loopback to caller visited place schedule register, in authentication responses, carry called user information; Caller visited place schedule register passes through caller visited place dispatch server by authentication responses message;
Step 409: caller visited place dispatch server records called party information, sends paging request to caller visited place terminal called; Illustrate: in this step, terminal called and calling terminal are positioned at same visited place;
Step 410: dialed field schedule register is received temporarily adding after calling authorization request of called subscriber, to the called authentication of carrying out, and by authentication responses loopback to caller visited place schedule register, in authentication responses, carry called user information; Caller visited place schedule register passes through caller visited place dispatch server by authentication responses message;
Step 411: caller visited place dispatch server records called party information, sends call setup indication to called visited place dispatch server; Illustrate: in this step, terminal called and calling terminal are not positioned at same visited place;
Step 412: caller visited place terminal called access calling, pages reply to the dispatch server loopback of caller visited place;
Step 413: caller visited place dispatch server is received paging reply after message of calling and called, according to call setup condition (except caller, must have a called access calling), judge this and called out successfully foundation, to calling terminal, authorize right of speech;
Step 414: calling terminal is to the dispatch server loopback authorization response of caller visited place;
Step 415: caller visited place dispatch server receives after the authorization response message of calling terminal, the caller visited place terminal called having accessed in giving self-built group sends right of speech prompting;
