Detailed description of the invention
Solution for embodiment of the invention is mainly by the number between configuration caller gateway and associated gatewayMatching list, in the time of communicating interrupt between Access Network and core net, can be by searching numbers match table, fromThe associated gateway of coupling is that the call number of caller gateway is mated corresponding called number, realizes spanning gateway certainlySwitched call business.
As shown in Figure 1, one embodiment of the invention proposes a kind of based on SIP (SessionInitiationProtocol, application layer signaling control protocol) the method for spanning gateway self-exchange, comprising:
Step S101 is the numbers match table of caller gateway configuration associated gateway;
In the present embodiment, caller gateway and associated gateway can be to belong to passing through in same LANThe IAD of SIP communication, the present embodiment associated gateway refers to that same LAN is interior except caller gatewayOther IAD, in order to realize when the Access Network at caller gateway place and the core net communicating interrupt,User in this caller gateway still can carry out basic communication service with user in other gateway, is firstOther IAD of caller gateway configuration be the concrete little directory of associated gateway be numbers match table (orNumber analysis), this numbers match table should be tried one's best accurately, so that called number can be in other gatewaysUniquely determine or definite among a small circle in, configure the protocol IP address of corresponding gateway simultaneously. By this numberMatching list, can search the corresponding of each calling subscribe calls out in caller gateway called number and associated gatewayMatching relationship, called number can coupling associated gateway in unique determine or can be at a fewThe interior among a small circle of gateway (one or more) determined.
Step S102, when Access Network and the core net communicating interrupt at caller gateway place, and called number is notWhile belonging to this caller gateway user, carry out caller gateway and phase according to numbers match table and by SIP signalingClose the self-exchange call business between gateway.
Core net can be the core net such as IMS, NGN in the present embodiment, when connecing of caller gateway placeNetwork and core net communicating interrupt, the i.e. uplink service interface of the Access Network at caller gateway place and core netBetween communication occur interrupt time, caller gateway judges according to called number whether this called number is Home NetworkClose user, if this called number is not the user in this caller gateway, according to above-mentioned numbers match tableCarry out numbers match, and by SIP signaling sequence or parallel can mate this called number to otherEach (one or more) associated gateway request of making a call. The each associated gateway of caller gateway waits afterwardsResponse, until receive from the called successful respond message of coupling of associated gateway or mate called failureResponse message, then processes accordingly according to response message, or wait timeout is released for calling subscribePut this calling. If called, the match is successful and called subscriber's free time, relevant in caller gateway and couplingBetween gateway, carry out call proceeding, complete spanning gateway self-exchange call business; If called, it fails to match,For calling subscribe discharges this calling.
As shown in Figure 2, in step S102, carry out caller gateway according to numbers match table and by SIP signalingAnd the self-exchange call business between associated gateway specifically comprises:
Step S1021 searches the associated gateway of mating with called number from numbers match table;
Step S1022, by SIP signaling sequence or the parallel associated gateway request of making a call to coupling;
In the present embodiment, between each IAD, communicate by letter by SIP signaling, if caller gateway and phaseClosing between gateway is serial communication pattern, can be by SIP signaling successively to the associated gateway that can mateThe request of making a call, until can confirm called number place associated gateway, or all associated gateway all withoutThis called number. If between caller gateway and associated gateway be parallel communications pattern, caller gateway is sameTime to the request of making a call of the associated gateway that can mate, and wait for each coupling associated gateway reply soundShould.
Step S1023, receives the associated gateway of coupling according to the response message of call request feedback;
In the time that the associated gateway of each coupling is received the call request of caller gateway, carry out separately called numberCoupling, according to matching result, to caller gateway feeding back response information, this response message comprises: mate calledSuccessful respond message or mate called failed response message.
If in the given time, not feeding back response information of the associated gateway of coupling, the meeting of caller gatewayTo the not associated gateway request that makes a call in triplicate of feedback, if wait timeout is released to calling subscribePut this calling.
Step S1024 according to response message, calls out between caller gateway and the associated gateway of matingContinue, complete calling and called call; Or, for calling subscribe discharges this calling.
In the present embodiment, after step S1021, also comprise:
Step S1025, if all associated gateway all do not mate with called number, for calling subscribe discharges thisInferior calling.
The present embodiment, still can be with general connecing in the time that interrupting appears in communication between Access Network and core netMouthful, between user, realize to greatest extent basic service, thereby the business of user of access network is providedSafer guarantee.
As shown in Figure 3, another embodiment of the present invention proposes a kind of side of the spanning gateway self-exchange based on SIPMethod, comprising:
Step S301 is the numbers match table of caller gateway configuration associated gateway;
Step S302, when Access Network and the core net communicating interrupt at caller gateway place, and called number is notWhile belonging to this caller gateway user, carry out caller gateway and phase according to numbers match table and by SIP signalingClose the self-exchange call business between gateway.
Step S101 and step S102 phase in above-mentioned steps S301 and step S302 and above-described embodimentWith, be not described in detail at this.
Step S303, when Access Network and the core net communicating interrupt at caller gateway place, and called number belongs toIn the time of this caller gateway user, in caller gateway, carry out call proceeding, complete calling and called call.
In the present embodiment, in the time of the Access Network at caller gateway place and core net communicating interrupt, if callerGateway judges that in call business, called number belongs to the user in this caller gateway, in this caller gatewayCarry out self-exchange call business, complete calling and called call.
Describe this in detail as an example of the telex network between four IADs in a LAN example belowEmbodiment method flow:
If the access gateway AG 1 based on SIP, AG2, AG3, AG4 in the same network segment of LAN,The concrete little directory that each gateway configuration is removed other gateway outside the Pass Home Network is numbers match table, and rightAnswer the protocol IP address of gateway.
When original state, AG1, AG2, AG3, AG4 all can with core net normal communication, logical separatelyCross protocol interface and equipment of the core network and carry out communication, complete calling interaction.
When occurring when network failure, AG1, AG2, AG3, AG4 all with core net communicating interrupt, butBetween each AG, communication is normal. Taking AG1 as example, AG1 proceeds to self-exchange state.
User's off-hook on AG1, AG1 is put dialing tone for this user; Subscriber dialing; AG1 collects the digits, andCarry out numbers match according to numbers match rule.
First, AG1 judges whether the called number that user dials is this gateway user, if so, at thisIntra-gateway directly carries out call proceeding, completes calling and called call, until end of conversation completes this time and exhalesCry; Otherwise, if not this gateway user, with pre-configured AG2, AG3, the number of AG4Matching list table mates, according to the match condition of the numbers match table of called number and other each gateway,Send call request to each gateway A G that can mate. If each gateway does not all mate, be directly mainThe code of calling out the numbers is that calling subscribe is put busy tone, waits for calling number on-hook, discharges this calling.
Suppose that called this number all mates with AG2, AG3, AG4. If AG1 and AG2, AG3 withAnd communication is serial mode between AG4, AG1 sends call request to the gateway that can mate successively(INVITE) message, until can confirm called number place gateway, or all gateways are all without this number.If communicate by letter between AG1 and AG2, AG3 and AG4 as parallel schema, AG1 is simultaneously each to all the otherGateway sends INVITE.
Afterwards, AG1 waits for the response message of other gateway, in wait state, if overtime, toThe each AG that does not receive reply retransmits three INVITE, does not still receive response message, thinksNetwork is obstructed, discharges this time and calls out, this end of calling.
When AG2, AG3 and AG4 receive after INVITE, carry out separately the coupling of called number,Send response message according to matching result to AG1: if can not mate called number, reply to AG1Mate called failure (404NotFound) message; If can mate called number, enter normally and exhaleBe flow process, reply corresponding response message according to current called subscriber condition to AG1: if this called subscriberJust busy, reply the busy 486BusyHere message of user to AG1; If this called subscriber is just idle,Reply 180Ringing message to AG1, represent called subscriber's free time, and to called subscriber's ring.
Caller gateway A G1 makes respective handling according to the response message of each gateway feedback:
If AG1 receives the 404NotFound message that AG2 replys, know that called subscriber is not on AG2,AG1 checks whether also have dont answer gateway. If have, do not deal with, continue to wait for; Otherwise, if each netGuan Jun has replied 404NotFound message, knows that called subscriber can not shut by pair net all, thereforeAG1 is that calling number is put busy tone, discharges this time and calls out, this end of calling after the on-hook of wait calling number.
If AG1 receives the 486BusyHere that AG3 replys, know called subscriber on AG3 and at presentJust busy, AG1 is put busy tone to calling number, after the on-hook of wait calling number, discharges this time and calls out, and this is exhaledCry end; If AG1 receives the 180Ringing that AG3 replys, know that called number is on AG3, because ofThis puts ring-back tone for calling number, enters next step.
Called subscriber's off-hook, AG3 sends OK to AG1, and calling and called user enters talking state, callerNumber is by typing call on ticket, until user's on-hook.
If calling number on-hook, AG1 sends BYE message to AG3, and will finish air time typingTicket, AG3 receives the BYE message that AG1 sends, for called subscriber is put busy tone. Called subscriber hangsMachine, discharges this time and calls out, this end of calling.
If called subscriber's on-hook, AG3 sends out BYE message to AG1, and AG1 receives what AG3 sentBYE message, for calling number is put busy tone, and is recorded to call ticket by the end air time. Main calling out the numbersCode on-hook, discharges this time and calls out, this end of calling.
Wherein, call ticket is produced by caller gateway, can keep in caller gateway, also can pass to netPipe or accounting server.
Method described in the employing embodiment of the present invention, the Access Network between different manufacturers configures spanning gateway simultaneouslyOwn exchange traffic, once Access Network uplink service interface and core net generation communicating interrupt, each IADCan automatically switch to self-exchange state, not only can realize the self-exchange call business of IAD inside,If IAD can with other IAD communication in LAN, can also be at each Access NetworkBetween pass, realize spanning gateway self-exchange call business, thereby can utilize to greatest extent Internet resources, protectBasic communication service between barrier gateway.
