Description
Background
The present invention generally relates to communication system, and particularly relates to and be used for the technology and the structure that connect in cellular communication environment, and this cellular communication environment comprises telecommunications and two kinds of networks of data communication.
Global system for mobile communications (GSM) has been described the European standard and the corresponding Public Land Mobile Nerwork (PLMN) of a communication, and its objective is provides consistency, and the equipment compatibility problem is minimum so that the user can insert everywhere arbitrarily the communication system of gsm system.Like this, the PLMN telecommunication system just provides the ability of freely travelling and the mobile service that wherein provides being provided for the mobile subscriber in gsm system.
Fig. 1 represents the conventional wireless GSM telecommunications network of a demonstration.Traditional wireless GSM telecommunications network generally comprises base transceiver station (BTS), base station controller (BSC), the mobile switching centre (MSC) of visitor location register (VLR) is housed, and the attaching position register (HLR) with authentication center (AuC).Each BTS is that each sub-district or the regional one or more travelling carriages (MS) that are positioned at wireless network provide communication.A BSC is controlling the operation of one or more BTS.BSC and MSC are interconnected, and MSC is delivered to predetermined destination (for example, public switch telephone network PSTN) to information.Each MSC is associated with a HLR and VLR.HLR is storing positional information and user data, and the latter has defined the business that each travelling carriage is authorized to use.VLR is currently located at the interior travelling carriage storaging user data of corresponding MSC service area for those.Can be about the other information of conventional wireless telecommunications network referring to No. the 5867788th, the United States Patent (USP) of No. the 5862481st, the United States Patent (USP) of Kulkarni etc. and Joensuu, these two patents are introduced especially in the lump with here as a reference.
In traditional telecommunications scheme, when travelling carriage entered a new MSC overlay area or travelling carriage and is activated, travelling carriage was at first attempted the registration to the MSC of service.Travelling carriage is finished enrollment process by send a sign that is associated (as IMSI International Mobile Subscriber Identity (IMSI) number) to the MSC that serving.The people who is familiar with this area will understand, and IMSI is by the MSISDN of system map to travelling carriage.After this Fu Wu MSC uses this information to communicate by letter with the concrete HLR of the user profile of the travelling carriage of storing the request of sending, so that notify the reposition of this travelling carriage of HLR, and fetches user profile for this travelling carriage from HLR.This user profile is downloaded on the VLR of service MSC.Fu Wu MSC uses the authentication test that this user profile is carried out any request then.In case satisfied authentication test, MSC just provides the business that is defined by user data to travelling carriage.
Fig. 2 explanation conventional telecommunications scheme in the ANSI41 system is used for setting up between first travelling carriage of initial MSC overlay area and second travelling carriage in the service MSC overlay area and calls out.In step a, initial MSC receives from the call origination request of first travelling carriage with by the travelling carriage address bit of dialling (i.e. the directory number of second travelling carriage).Initial MSC sends a Location Request (LOCREQ) message (step b) to the HLR of the user profile of storage second travelling carriage.If distributed to legal users by the travelling carriage address bit of dialling, HLR just sends route requests (ROUTREQ) message (step c) to the VLR of the current registration of second travelling carriage.VLR transmits route request information (step d) to service MSC then.As the response to the route request message, this MSC asks business information (being the user data) (step e) of second travelling carriage to VLR.If second travelling carriage was registered at VLR in the past, thereby not by known to the VLR, perhaps the MSC information requested does not exist on VLR, and then VLR is to HLR solicited message (step f).In response, HLR sends requested information to VLR (step g), VLR then gives the information route service MSC (step h).Service MSC distributes an interim local directory number (TLDN) for second travelling carriage, and this information is returned to VLR (step I), and VLR then returns to HLR (step j) with information.
TLDN is the interim routing number that is used for to service system transmission calling.Receiving that from starter system one is disengaged distribution for concrete calling TLDN after setting up message, the TLDN that is used as called party address in starter system is mapped to corresponding recipient's sign (as IMSI).The call setup technical limitations is in ISUP or the registration signaling (as SS7 or CAS) that is tightly linked with the transmission technology that adopts.
After HLR had received TLDN, it was to initial MSC restoring to normal position request response message (step k).After this utilize the routing iinformation that illustrates in existing interconnection agreement (as SS7) and the Location Request response message, initial MSC is set up to the voice path (step l) of service MSC.
Although voice have been and be a part important in the mobile communication with continuing, in the past ten years, the consumer uses mobile communication equipment to transmit data rather than voice more and more at large.The possibility that sends and receive Email, uses Web-browser to obtain the World Wide Web (WWW) access just is being used as the business that will use more and more and is discussing warmly in wireless communication system.Like this, following communication system may comprise the combination of communication network and data network, but by these network routing calls.As a result, provide competitive advantage, revise existing phone addressing technique and be necessary in order to give to use in the data communication industry based on IP or based on the telecom operators/service provider of the addressing scheme of other data communication.
Existence is promptly revised the addressing scheme of conventional telecommunications system to the demand of such system and method, so that promote call establishment in the environment that comprises the combination of telecommunications and data communication network.

In this, service system can be selected between different grouping calling route option based on service system ability and starter system ability.Following option is possible:
1) returns a VNP, comprise for example IP address to starter system.In starter system, the PLMN gateway is forwarded to the ISP network to the address of receiving.The ISP network is then set up a new session to the address that is provided by VNP.
2) return an E.164 route numeral of type (as an interim local directory number (TLDN)) to starter system.This route numeral is then made by the PLMN gateway in starter system and is used for setting up and being connected of service system.This option can not supported under those situations of VNP selected in system.
Expired if distribute to user's IP address in the past, then a new IP address will be comprised in the route requests return results as VNP.Home System is stored this new routed ip address, and it is included in the response of the position requests that returns to starter system.If the ability of the protocol capability of service system and starter system does not match, then Home System can select to have the ability to handle another gateway of agreement mapping between service system and the starter system, so that there is the connection of a success to set up the result.Home System can be chosen in the address (reorientation method) that comprises this gateway in the response to starter system, and perhaps Home System uses an acting server to connect (Proxy Method) and notify the address and the connection state information (as method of attachment and result) of this gateway of starter system to service system by gateway.Starter system then connects or is accomplished to the connection of gateway to service system by gateway, and wherein the connection from the gateway to the service system was set up in the past.If any fault (for example acting on behalf of fault etc.) occurs when gateway is connected to service system, then starter system is notified to suitable fault message.
Fig. 5 A and 5B represent top described being redirected and Proxy Method.In Fig. 5 A, a user in initial network sends a position requests to Home System when attempting to locate a registered user, wherein especially comprises the protocol capability (step 501) of starter system.In response, home network sends a request (step 502) to service network, this service network is located registered user and is distributed suitable resource (notice, in the example of the back of this example and corresponding diagram 5B, suppose that Home System does not comprise effective VNP of user).Together with the protocol capability of service network, service network sends a VNP (step 503) to home network.At definite service network with after initial network has different protocol capabilities, home network select one can the processing protocol mapping gateway.Home network comprises the address (step 504) of this gateway in sending to the message of initial network.Initial network is then sent connection request (step 505) to this gateway, and this gateway is set up be connected (step 506) with service network.After this, this user and registered user communicate (step 507a and 507b) via this gateway.
Fig. 5 B represents to be used for the Proxy Method that connects between the network with different agreement ability.In step 551, the user in initial network sends a position requests to home network when attempting to locate a registered user, wherein especially comprises the protocol capability of initial network.In response, home network sends a request (step 552) to service network, and the latter locatees registered user and distributes suitable resource.Together with the protocol capability of service network, service network sends a VNP (step 553) to home network.At definite service network with after initial network has different protocol capabilities, home network select one can the processing protocol mapping gateway.Home network is set up be connected (step 554-556) with service network by using acting server through this gateway.In step 557, home network is then notified the address and the connection state information (as method of attachment and result) of the relevant gateway of initial network.Starter system is then finished be connected (step 558 and 559) with this gateway.
Fig. 6 is illustrated in the use of virtual-number parameter of the present invention in second exemplary transaction processing, wherein in starter system (as ISP (ISP)) with roam between the travelling carriage in the visit system (as PLMN) and set up a connection, starter system and Home System have the protocol capability of coupling here.Because the protocol capability that starter system and Home System have coupling is not so the initial network of Fig. 6 comprises the PLMN gateway.
Similar to exemplary transaction processing shown in Figure 4, the user of internet attempts to locate a registered user who roams at present among the PLMN.Because as previously mentioned, Home System has the ability of directly communicating by letter with ISP or other data communication network, so do not need gateway.Like this, ISP directly sends a position requests to Home System, wherein especially comprises callee's the address and the protocol capability of starter system.
Comprise at the HLR of Home System under user's the situation of an effective VNP, VNP is routed to starter system from HLR.When HLR did not comprise effective VNP of user, Home System was initiated a request to service system and is connected this user.This registered user of service system paging then distributes a Traffic Channel if desired and keeps desired data processing resource (as IWF).
Expired if distribute to registered user's IP address in the past, then new IP address be comprised in from the route requests return results of service network as VNP.As previously mentioned, the route requests return results also can comprise the use that a timer is used for monitoring VNP.Home System is stored new IP address and it is included in the response of the position requests that returns to starter system (being ISP).The Internet Protocol ability of service system also is comprised in the response to starter system.Under the situation of the protocol capability of those starter systems and service system coupling, the IP address that provides by service system is provided, just call out and directly be established to service system from ISP.If the protocol capability of service system is different from the protocol capability of starter system, then Home System can be selected to adopt and be redirected as mentioned above or Proxy Method foundation calling.
Fig. 7 represents to adopt the exemplary call of VNP of the present invention to transmit transaction.The exemplary transaction that is similar to above-mentioned corresponding diagram 4 is handled, and calls out between the registered user in an ISP and PLMN and sets up.Here supposition, in response to request from Home System, service system return one E.164 the TLDN of form give gateway.Starter system then uses the TLDN that is provided by service system to connect.If also not response of registered user after a predetermined overtime phase, service system just send a redirect message to starter system and represent that the registered user does not respond.Comprise at those redirect messages under the situation of Redirect Address (being VNP), starter system uses this address to connect.Yet when redirect message did not comprise a Redirect Address, starter system was from Redirect Address of Home System request.Home System sends VNP to starter system, and the connection of the address that is provided by VNP then is provided starter system.
