Description of drawings
By below reading as non-limiting example and the description that provides with reference to accompanying drawing, the present invention may be better understood, in the accompanying drawings:
Fig. 1 is the figure that realizes the device of call-establishing method of the present invention;
Fig. 2 is to use the figure of first embodiment of Fig. 1 device of calling party's route; And
Fig. 3 is to use the figure of second embodiment of Fig. 1 device of callee's route.
Embodiment
In the accompanying drawings, first user attempts to set up the calling from the first terminal T1 (telephone terminal) to second user's the long-range second terminal T2, and the second terminal T2 is connected to the IP network such as the internet.Below, the first terminal T1 typically is the GPRS mobile telephone terminal, but it can be the fixed telephone terminal that communicates by the corresponding telephone network equally.The long-range second terminal T2 for example is the fixing or mobile computer that is connected to IP network, and below be referred to as the IP terminal.
The architecture that is connected that is common to the user of GPRS portable terminal T1 and IP terminal provides predefined dynamic routing rule, is connected up to the called subscriber with the calling of guaranteeing to enter into the gateway (as the PSTN/IP gateway) between first and second terminal.
Be used for the same of instant message (Instant Messaging) with those, the normally IP-based existence management of such architecture (presence management) architecture.
In this connection architecture, discern the second terminal T2 by the second predetermined identifier ID 2, second identifier ID 2 is not telephone number usually, and the e-mail address that comprises the second terminal T2, as (in France) forename.name@domain.fr, wherein ' name ' and ' forename ' is second user's name and name.Identifier ID 2 makes the user that wins lack distinguishing feature to second user's identification unlike telephone number.
In the accompanying drawings, this connection architecture comprises one or more Connection Service device SMR described below and mapping table TC.
Utilize this public connection architecture, first and second users can coexist as in the same identification space (identification space), and the first terminal T1 can get in touch Connection Service device SMR, and Connection Service device SMR can get in touch the second terminal T2.Calling from the first terminal T1 to server S MR uses GPRS telephone network, GPRS to connect and the internet, and vice versa on opposite direction.The internet is all used in calling between the server S MR and the second terminal T2 on both direction.For example, IP address and port that the second terminal T2 for example can get in touch the second terminal T2 by notice are notified its existence and proceed to the connection (initiatively carried out or carried out automatically by permanent connection by second user) of Connection Service device SMR in advance when the second terminal T2 are connected.Carrying (onboard) by client application among the second terminal T2 and plate among the first terminal T1 uses and is implemented to being connected of service.These use to use IP connectivitys to set up and being connected of server S MR.Such architecture normally based on have management agreement XMPP (eXtensible Messaging and Presence Protocol, scalable message is handled on-the-spot agreement), SIMPLE (SIP for Instant Messaging and Presence LeveragingExtensions, instant messaging dialogue initiation protocol and expression Extended Protocol) and the compatible element of Wireless Village (wireless village, registered trade mark).For example, connecting architecture makes among first and second users each can both draft contact person or call intent ground tabulation (" good friend " tabulates).The existence of the second terminal T2 on the IP network is notified to the first terminal T1, and the existence of the first terminal T1 on the mobile telephone network is notified to the second terminal T2.
In order to make a call and to be connected to service provided by the invention and to be connected to server S MR, during step 1, the user selects second identifier ID 2 on the first terminal T1, and orders the first terminal T1 to use communication protocol to send the call request DA that comprises second identifier ID 2 to Connection Service device SMR.For example, first user keys in second identifier ID 2, because the user knows it by chance, perhaps the plate among the first terminal T1 carries application based on second identifier ID, 2 promptings, first customer call, second user who connects the second terminal T2 in the architecture, for example by select the terminal T2 of serviced device SMR detection for existing in the contacts list of pointing out the user to store from terminal T1.
When each Connection Service device SMR receives call request DA, in step 2, it is associated the first telephone number NT with the called party identifier ID2 that wherein comprises, and should association be stored among the mapping table TC temporarily, under applicable situation, also the first telephone number NT can be associated with other characteristics of calling out in the future.For each call request that it receives, server S MR is interim and dynamically definite first telephone number NT according to call request DA.This first telephone number NT is a service number, therefore it is not distributed to identifier ID 2 with static state and definite mode, but just at call establishment stage, for example till in step 8, setting up calling between the first and second terminal T1 and the T2.Therefore, the association between the identifier ID 2 and the first number NT dynamically is stored among the mapping table TC.
In first embodiment shown in Figure 2, call request DA comprises the telephone number N1 and second identifier ID 2 (callee) of first terminal (calling party) that sends call request.In this case, the first telephone number NT is the calling party phone number N1 that sends first terminal of call request DA.
In second embodiment shown in Figure 3, call request DA does not comprise the telephone number N1 of first terminal (calling party) of transmission, but comprises second identifier ID 2 (callee).In this case, the first telephone number NT is that server S MR is the definite service number NS of call request DA that comprises identifier ID 2.For example, this service number NS is determined from special services list of numbers (pond) LNS that is used for hanging up call request, server S MR and reserves by server S MR, and is assigned to the call request DA that comprises identifier ID 2.Therefore, when call request arrived server S MR, these service number NS can be assigned to any identifier ID 2.
Then, in step 3, after the ID2-NT association was stored among the table TC, Connection Service device SMR came answering call request DA by the ack signal that sends message or correspondence to the first terminal T1 that sends call request DA.
The first terminal T1 receives this and replys and make it send incoming call AE to the second number NS (service number) that sends the first terminal T1 in for example this is replied to automatically during step 4.By the routing rule of setting up in advance in the application phone network, this second number NS (service number) connects up to being used for setting up the gateway PEA that calls out between first and second terminal T1 and T2.Incoming call AE is transparent for first user of the first terminal T1.
Incoming call utilizes the SS7 signaling to arrive gateway PEA by telephone network.Incoming call AE comprises characteristic CAR, and it is notified to server S MR with the relation between the first number NT and the second number NS (service number).This characteristic CAR make it possible to use subsequently the first number NT come to select in the association from mapping table TC a particular association (ID2, NT).
Among first embodiment based on calling party T1 and calling party phone number N1 routing call, the second number NS is a service number therein, therefore is different from the first number NT=N1.For example, this service number NS is determined from special services list of numbers (pond) LNS that is used for hanging up call request, server S MR and reserves by server S MR.Therefore the characteristic CAR of incoming call AE for example is that (N1 → NS) is to specify the calling from the first terminal T1 with telephone number T1 to (service) the second number NS for AE.
(service) second number NS or service number tabulation LNS are normally reserved for the service provider in advance by telephone number allocation manager mechanism, and set up suitable routing rule so that these service number are routed to the gateway PEA of this service-specific usually in fixing or mobile telephone network.
Therein among second embodiment based on the callee's number NS routing call among the incoming call AE, therefore (service) second number NS equals the first number NT that shows to be associated with identifier ID 2 among the TC.Therefore, the characteristic CAR of incoming call AE for example includes only the record AE (NS) of (service) the second number NS in the incoming call, this means that the relation between the first number NT and (service) second number NS is NT=NS, and need in incoming call AE, not send the telephone number N1 of the first terminal T1.
When gateway PEA receives incoming call AE, it is stored as (service) second number NS the incoming call of hang-up in step 5, so that be connected to purpose IP terminal later on, and for example send the incoming call AE signal that receives to server S MR (signaling SAE) by the internet.This signaling SAE sends the data that comprise among the incoming call AE, comprises (service) second number NS and characteristic CAR; Therefore in first embodiment, the data of transmission comprise telephone number N1 and (service) second number NS of the first terminal T1, and in a second embodiment, the data of transmission include only (service) second number NS.In first embodiment, signaling SAE also can include only the telephone number N1 of the first terminal T1.
When server S MR receives the signaling SAE of incoming call AE, it extracts the characteristic CAR of incoming call AE from this signaling, and consult the record that exists among the mapping table TC, to determine as the called party identifier function of CAR and TC, that be associated among the mapping table TC.Server S MR determines among the mapping table TC (callee's) second identifier ID 2 of being associated with (corresponding to the signaling SAE's of the characteristic CAR of incoming call AE) first number NT like this.
In first embodiment, (N1 → NS) or CAR (N1) compare with record among the table TC characteristic CAR=AE that server S MR transmits signal, the characteristic CAR=AE that transmits based on signal (N1 → NS) or the record (ID2 among CAR (N1) the option table TC, N1), and release record (ID2, N1) second identifier ID 2 of that exist in and terminal T2 that be associated with the number N1 that exists among the characteristic CAR that signal transmits, caller rs number N1 makes record (ID2, N1) the discrimination factor of server S MR in can option table TC.
In a second embodiment, server S MR compares signal characteristic CAR=AE (NS) that transmits and the record of showing among the TC, based on the record (ID2 among characteristic CAR=AE (NS) the option table TC of signal transmission, NS), and release record (ID2, NS) second identifier ID 2 of that exist in and terminal T2 that be associated with (service) second number NS of existing among the characteristic CAR that signal transmits, service number NS is record (ID2, discrimination factor NS) that makes it possible among the option table TC.
When having determined (callee's) second identifier ID 2 by this way, Connection Service device SMR is sent to incoming call AE (incoming call notice) signal the second terminal T2 (callee) corresponding to this second identifier ID 2 in step 6.This signaling SAE2 of incoming call AE is sent to the second terminal T2 by the internet.
When receiving signaling SAE2, the second terminal T2 sets up multimedia communication channel CC via internet and gateway PEA in step 7, for example, and voice and/or picture channel (as the voice on the IP (VOIP) channel).Based on other characteristics that in signaling SAE2, offer the second terminal T2 (characteristic that for example in step 4, from incoming call AE, obtains and in signaling SAE, transmit), set up this communication channel CC.These other characteristics are relevant with the characteristic that for example is the voice-channel assignment on the IP.Certainly, the user of terminal T2 (second user) can refuse to allow to set up to call out, and this will stop the execution of step 7 and 8.
At last, at next step, in the step 8, gateway PEA will be connected to the incoming call AE (it keeps the incoming call of hang-up) corresponding to (service) the second number NS with the communication channel CC that the second terminal T2 sets up.Therefore between the first terminal T1 and the second terminal T2, be communicated with calling end-to-endly.So the first terminal T1 and the second terminal T2 can intercom mutually via the gateway PEA that the IP/PSTN that provides between them changes and exchange sound and/or image.Certainly, described method can be used between other first terminals and other second terminals.
In step 2, server S MR also can be with (calling party's) first identifier ID 1 of existing among the call request DA or caller service identifier ID 1 (promptly, the identifier of the caller first terminal T1), store explicitly with (callee's) second identifier ID 2 or callee's service identifier ID2.
For example, server S MR uses calling party's first identifier ID 1 to verify the first terminal T1 of this service of subscription, if and it finds that first identifier ID 1 that exists among the call request DA belongs to the user file that is stored in advance among the server S MR, then carry out other steps of this service, if perhaps it finds that first identifier ID 1 that exists among the call request DA does not belong to the user file that is stored in advance among the server S MR, then stop the execution (for example, not replying ACK) of other steps of this service by in step 3, not sending to the first terminal T1.Server S MR can refuse to reply ACK to first terminal T1 transmission for other reasons in step 3, for example since it to detect the credit rating or this credit rating that have surpassed corresponding to first identifier ID 1 of call request DA in its database out of date, and/or because it detects the service number NS that temporarily can use without any incoming call AE, reason is that they all were assigned to incoming call AE at that time, and/or since first identifier ID 1 that it detects call request DA be in its management and comprise and getting rid of on the blacklist of calling out.
For example, also send calling party's first identifier ID 1 among the incoming call AE that signal transmits in step 6, so that show second user on the second terminal T2.
After in step 8, set up calling out, server S MR can be from table TC related between deletion second identifier ID 2 and the first number NT (ID2 NT), and under applicable situation, also can delete the information that other are associated.
