Introduce the registration process of a plurality of servers of terminal attaching that the embodiment of the invention provides earlier, behind the starting terminal, on 3 servers, register respectively, and the priority on each server of designated terminal ownership.The log-on message at each this terminal of server for saving, log-on message has comprised terminal iidentification, the sign of attribution server, and the priority of terminal attaching server, log-on message can be preserved with the form of registration table, shown in table one:
| Terminal iidentification | Server identification | The priority of terminal attaching server |
| Terminal A | Server A | 1 grade |
| Terminal A | Server B | 2 grades |
| Terminal A | Server C | 3 grades |
Table one
In above-mentioned table one, the rank of the priority of terminal A attribution server is with 1 grade, and 2 grades, 3 progressive line displays; Wherein 1 grade of rank is the highest, and 2 grades of ranks are inferior to 1 grade of rank, but is higher than 3 grades of ranks, and 3 grades of ranks are minimum; Certainly, be a kind of method for expressing of priority of terminal attaching server here, can also be otherwise; Such as: use rank A, B, C distinguishes priority.
In the process of terminal to server registration, the terminal can adopt multiple mode to carry out the priority of designated terminal attribution server.Can be according to number section rule; The priority of designated terminal attribution server, for example: for number section is the user of 0755XXXXX, and the priority of its terminal attaching server is: server A is higher than server B; Server B is higher than server C; And be the user of 0756XXXXX for number section, the priority of its terminal attaching server is: server B is higher than server A, and server A is higher than server C.Also can be according to the domain name of termination number; The priority of designated terminal attribution server, for example: for the user of " SIPUserName zone A ", the priority of its terminal attaching server is: server A is higher than server B; Server B is higher than server C; For " SIPUserName area B " user, the priority of its terminal attaching server is: server A is higher than server B, and server B is higher than server C.Certainly; The priority of terminal attaching server also can be dynamically adjusted at the terminal according to call information and user capability attribute; Call information can be: audio call and video call; Whether physical location, the terminal the when user registers at place had cryptographic capabilities when the user capability attribute can be registered for the user, and whether the terminal the when user registers has video capability etc.For example: when the type of calling out when the terminal is audio call, the user of " SIPUserName zone A ", the priority of its terminal attaching server is: server A is higher than server B, and server B is higher than server C; When the type video of calling out when the terminal is called out, the user of " SIPUserName zone A ", the priority of its terminal attaching server is: server A is higher than server B, and server B is higher than server C.
In embodiments of the present invention, the terminal can be registered on any several servers.
Fig. 2 has described the flow process of the processing method of the terminal receipt of call that belongs to a plurality of servers that one embodiment of the invention provides:
201, the request of the diverting call of first server transmission of the second server reception terminal called ownership of terminal called ownership; Comprised routing iinformation in the described request; Said routing iinformation has comprised each sign of traversal server; Wherein, said traversal server is the current server of having attempted handling the terminal called ownership of said calling;
202, said second server judges self whether to have the required full service ability of said calling, if having, confirms to handle said calling by said second server;
If 203 do not have; Said second server judges whether said routing iinformation has comprised the sign of all other servers of the terminal called ownership except that said second server; If comprise; The then said second server judgment processing of taking out stitches, if do not comprise, then inquiry is stored in the priority of other server of the ownership of terminal called described in the said second server; To the highest server of server medium priority of the said terminal called ownership except traversal server, send the request of diverting call.
In the embodiment of the invention; When receiving call request; According to the priority of terminal called attribution server and the service ability of server, select a priority-level server the highest and that ability is the strongest and handle this calling, thereby realized that terminal called belongs to the calling scheme of a plurality of servers; And ought certain server have wherein broken or with the connecting terminal of terminal called, this calling still can be processed.
Fig. 3 has described the flow process of the processing method of the terminal receipt of call that belongs to a plurality of servers that one embodiment of the invention provides; Wherein, in this scheme, suppose that terminal called belongs to a plurality of servers; Belong to server A, server B and server C respectively; The priority of its terminal attaching server is: server A is higher than server B, and server B is higher than server C, and server A, server B and server C all do not have the required full service ability of calling; Wherein the service ability of server B is maximum in server A, server B and server C, and then flow process comprises:
301, server A receives the call request that calling terminal is initiated, request call terminal called.
The terminal that Radix Angelicae Sinensis belongs to a plurality of servers is during as terminal called; If during attribution server A, call request can not be that the miscellaneous equipment from network sends in the server A to calling terminal, such as: miscellaneous equipment is MGCF; When this moment, MGCF called out route to call request; Through data configuration, can fix certain server that call request is sent to this terminal called ownership, as: server A; Also can this call request be sent in a plurality of servers of this terminal called ownership any one, as: server A.When if calling terminal belongs to server A, then server A directly receives this call request.
When server A confirms that the terminal called of this calling belongs to a plurality of server; Server A confirms whether the highest the priority of terminal called attribution server A is; If not the highest; Then inquire about the highest corresponding server of priority of terminal called attribution server, call request is transmitted to this server; If it is the highest that terminal called belongs to the priority of server A, then execution in step 302.
302, server A judges whether server A self has the required full service ability of this calling, if having, then handles and should call out switching called terminal.If do not have, then inquire about the priority of each server of this terminal called ownership, to except server A, the server that the server priority of terminal attaching is the highest sends the request of diverting call.
Service ability can have multiple, comprising: be connected with application server normally, server has the service ability of the business that the terminal customization is provided, such as Ring Back Tone service; Be connected normally with HSS, server has in calling procedure inquiry, and some only is kept at the ability of the information on the HSS, like the filtering policy information at terminal and location information of terminals etc.; Be connected normally with MRF, server has the ability that media services are provided for calling, like playback, collect the digits etc.; Normal with the unit status of server, server has the ability that the call treatment service is provided for the user.Call out to difference, required full service ability can be different.For example certain type of calling need not used media resource, and server carries out can need not when full service ability is judged considering the connection status with MRF to such calling so.
The log-on message of server A inquiry terminal called; Confirm except terminal called belongs to server A; The priority that terminal called belongs to server B is the highest; Server A will generate the request of many diverting calls this moment, and this request has comprised shifts sign, current maximum service ability, the server identification with current maximum service ability and routing iinformation, and this request can also comprise the diverting call maximum times.Wherein, unique transfer sign that the session of a diverting call is corresponding; Current maximum service ability be used for representing each traversal server have the maximum service ability value; Wherein traversal server is the current server of having attempted handling the terminal called ownership of this calling; When the server of handling this calling as new trial has service ability greater than the current maximum service ability in this request; Then will this new trial handle service ability that the server of this calling has as new current maximum service ability; In step 302, current maximum service ability is the service ability that server A has; Server identification with current maximum service ability is used to represent to have the server of current maximum service ability, and in step 302, the server identification with current maximum service ability is the sign of server A; The diverting call maximum times is represented the current maximum times that can be transferred of this calling; Such as: it is 2 times that this diverting call maximum times is set, and when revolution moves once this calling, this diverting call maximum times subtracts one; Promptly after server receives the request of diverting call; This request diverting call maximum times will be subtracted one, and in step 302, this diverting call maximum times is 1 time; Routing iinformation has comprised each sign and each address of traversal server of traversal server; Wherein, Traversal server is the current server of having attempted handling the terminal called ownership of said calling; In step 302, this routing iinformation has comprised the address of server A, and the sign of server A.
303: after the request of the diverting call that server B reception server A sends, judge whether server B self has the required full service ability of above-mentioned calling,, then handle and to call out switching called terminal if having.If do not have, confirm then whether the diverting call maximum times that comprises in the request of current diverting call is 0, if be 0, the judgment processing of then taking out stitches; If be not 0; Then inquire about the routing iinformation that comprises in the request of priority and diverting call of each server of this terminal called ownership; To except each the highest server of server priority of the terminal attaching the traversal server, send the request of diverting call.
After the request of the diverting call that server B reception server A sends; The diverting call maximum times will subtract 1 in this request; Then current diverting call maximum times is 1, the diverting call maximum times that therefore comprises in the request of current diverting call is 1, and current except server A and server B; Server C has limit priority, then sends the request of diverting call to server C.
Before sending the request of diverting call to server C, the current maximum service the ability whether service ability that server B also need be judged server B comprises the request greater than the diverting call that receives from server A.If greater than, the current maximum service ability that then comprises in the request with diverting call is revised as the service ability of server B, and revises that to comprise the server identification with current maximum service ability in the request of this diverting call be the sign of server B.If be less than or equal to, the current maximum service ability that then comprises in the request of diverting call is constant with the server identification with current maximum service ability.
In addition, before sending the request of diverting call to server C, server B increases the address of server B and the sign of server B in the routing iinformation that the request of diverting call comprises.
In addition, if except each the traversal server, terminal called has not had the server of ownership, that is: the server of terminal called ownership has all carried out full service ability and has judged the judgment processing of then taking out stitches.
In another one embodiment of the present invention,, need not then to judge whether the diverting call maximum times is 0 if the request of diverting call does not comprise the diverting call maximum times.
304: after the request of the diverting call that server C reception server B sends, judge whether server B self has the required full service ability of above-mentioned calling,, then handle and to call out switching called terminal if having; If do not have, confirm then whether the diverting call maximum times that comprises in the request of diverting call is 0, if be 0, the judgment processing of then taking out stitches; If be not 0; Then inquire about the routing iinformation that comprises in the request of priority and diverting call of each server of this terminal called ownership; To except each the highest server of server priority of the terminal attaching the traversal server, send the request of diverting call.
After the request of the diverting call that server C reception server B sends; The diverting call maximum times will subtract 1 in this request; Then current diverting call maximum times is 0, and the diverting call maximum times that therefore comprises in the request of current diverting call is 0, then gets into the judgment processing of taking out stitches.
The judgment processing of taking out stitches process is following: the current maximum service the ability whether service ability that server C judges server C comprises the request greater than the diverting call that receives from server B.If greater than, promptly in a plurality of servers of terminal called ownership, the maximum service ability that server C has is selected the server of server C as call treatment, and then server C carries out call treatment; If be less than or equal to, promptly in a plurality of servers of terminal called ownership, the maximum service ability that server B has; Select the server of server B as call treatment; Then according to routing iinformation, server C sends clear message to server B, removes this diverting call session.This clear message has comprised the server identification and the routing iinformation that shift sign, have current maximum service ability.Owing in the embodiment of the invention, suppose that the ability that server B has is higher than the ability that server A has, then this moment, server C sends clear message to server B.
305, server B receives the clear message that server C sends, and according to the server identification with current maximum service ability, confirms this calling of server B processing.Server B is carried out call treatment.
In embodiments of the present invention; Server carries out the call treatment detailed process can be following: server sends call request to terminal called; And send the ring response to calling terminal according to routing iinformation, that is to say, according to routing iinformation; Server B sends to server A with the ring response, and server A sends to the device that call request is sent in the step 301 with the ring response again.In call handling process, follow-up all-calls message all need be transmitted through server A.
When the server of supposing to have current maximum service ability is not server B, after then server B receives the clear message of server C, removes this diverting call session, and this clear message is sent in the server A.
In the embodiment of the invention; When receiving call request; According to the priority of terminal called attribution server and the service ability of server, select a priority-level server the highest and that ability is the strongest and handle this calling, thereby realized that terminal called belongs to the calling scheme of a plurality of servers; And ought certain server have wherein broken or with the connecting terminal of terminal called, this calling still can be processed.
In another one embodiment of the present invention, in call handling process, all need transmit through server A for fear of follow-up all-calls message; When certain server owing to self possess full service ability; Perhaps because self service ability is the strongest to confirm self for behind the processor of this calling in a plurality of servers of terminal called ownership, then server does not carry out call treatment immediately, and operates as follows: if server self is the originating server of diverting call; Then server is directly handled and should be called out; If server self is not the originating server of diverting call,, send clear message to previous server then according to routing iinformation; And the diverting call number added in the clear message; Wherein the diverting call number has comprised that many ownership land prefix and original called number, and when server receives when comprising these many ownership and landing the call request of prefix, this server will be forced this calling of processing.After originating server is received clear message; Carry out as judging and handling: if the calling terminal of this calling belongs to originating server, then handle clear message, after the dismounting diverting call session; Diverting call number according to comprising in the clear message makes a call to terminal called again.If the calling terminal of this calling does not belong to originating server; For example: this call request sends over from MGCF; Then send the request of calling again of initiating to this MGCF; Comprise server identification and diverting call number with current maximum service ability in this request, MGCF resends calling to the server of final this calling of processing according to this request indication.After MGCF receives the request that initiation calls out again; According to the server identification and the diverting call number of the current maximum service ability that comprises in the request, directly to the server request of making a call of current maximum service ability, this call request has comprised the diverting call number; After server receives this call request; Land prefix according to many ownership, do not do many ownership and judge and other judgements, directly processing.
A kind of structure chart of handling the server of terminal called calling as shown in Figure 4, that the embodiment of the invention provides is characterized in that, comprising:
First judging unit 42 is used to judge self whether to have the required full service ability of said calling,
First confirms unit 43, judges to have the required full service ability of said calling if be used for said first judging unit 42, confirms by self handling said call request;
Second judging unit 44 is judged and is not had the required full service ability of said calling if be used for said first judging unit 43, judges whether said routing iinformation has comprised the sign of the Servers-all of the terminal called ownership except that self;
The judging unit 45 of taking out stitches is judged the sign that said routing iinformation has comprised other server of the terminal called ownership except that self if be used for said second judging unit 44, the then said judgment processing of taking out stitches,
First transmitting element 46; If be used for the sign that said second judgment unit judges, 44 said routing iinformations do not comprise the Servers-all of the terminal called ownership except that self; Then inquiry is stored in the priority of each server of the ownership of terminal called described in self; To except each the highest server of server medium priority of the said terminal called ownership the traversal server, send the request of diverting call.
