Abstract
This invention relates to a method and system optimization of intelligent location register system in the field of communication technology, which includes: first, the calling terminal initiates call through the pre-established virtual circuit; intelligent location register gets the roaming number of the called number and returns to the calling terminal; when receiving the roaming number, calling terminal releases virtual circuit and re-routes according to the number, then launches call.
Description
Technical field
The present invention relates to communication technical field, relate in particular to a kind of method and system that speech channel is optimized that in the intelligent home location register system, realize.
Background technology
At present, along with development of Communication Technique, new business emerges in an endless stream, if provide new business by the large tracts of land change existing communication network equipment, must need to drop into substantial contribution, and the professional excessive cycle that provides can be provided, and can greatly influence the stability of communication network.In the face of above great number of issues, the implementation of stacking network has been proposed, promptly stack one cover intelligent equipment on the basis of existing communication network is called the OVERLAY mode, provides new business fast with this.
Shown in Figure 1, represented the networking diagram of fixed network (comprising PHS (personal handyphone system)) system's overlaying scheme, concrete technology is referring to " SHLR PCS roaming technology standard (V1.09) ".The basic ideas of this networking are: the PHS roaming is still finished by online original PHS built-in system, newly-increased SHLR (comprehensive intelligent attaching position register) is superimposed upon on the local PHS system, be used to solve allow mixing under PHS user's roaming condition to distribute telephone numbers, the whole network is intelligent and NP (number migration) problem of changeing net to 3G.
But such scheme has adopted ISUP (ip intelligent peripherals) to dock the transmission signaling between LS (fixed network end office (EO))/SSP (Service Switching Point) and SHLR, physical signaling reciprocal process as shown in Figure 2, the roaming number that LS obtains called PHS user is to send traditional isup message by LS/SSP to SHLR to obtain.Like this, in order to obtain the roaming number of a called PHS, in LS and two entities of SHLR, all must dispose traffic resource, and need increase corresponding transfer resource, and in fact this traffic resource there is no real use in system, only be because it has used general signaling ISUP signaling, and have to dispose these speech channels.So just cause the waste to traffic resource, especially in transfer resource anxiety or expensive place, this contradiction becomes increasingly conspicuous.
The method that another kind of prior art has proposed in the employing " SHLR PCS roaming technology standard (V1.09) " is routed to SHLR calling out by switching entity LS/SSP, and speech channel also is connected to SHLR.
The shortcoming of this technology has been to cause LS/SSP and the SHLR relaying veneer wasting of resources separately and the waste of transmission trunking resource.

Embodiment
Core concept of the present invention provides a kind of method and system that speech channel is optimized that realize in the intelligent home location register system, by between switch and intelligent home location register system, virtual circuit being set, do not connect the actual transmissions resource, avoided using actual speech channel to cause the waste of transfer resource, finished optimization, greatly reduced the investment and the maintenance cost of operation communication network traffic resource.
The invention provides and realize the system that speech channel is optimized in a kind of intelligent home location register system, a kind of embodiment framework of described system comprises as shown in Figure 3: switch LS, intelligent home location register system SHLR.Be provided with respectively in described LS and SHLR: virtual circuit is set up module and virtual circuit management module.Described virtual circuit is set up module and is used for setting up virtual circuit between described LS and SHLR, as the corresponding C IC1 of LS among Fig. 3 and SHLR to the circuit between the CICn.Described virtual circuit is a kind of logical circuit, does not carry out actual connection, does not connect the actual transmissions resource.Described virtual circuit management module is used to manage the virtual circuit after described virtual circuit is set up module foundation, guarantees that the state of described virtual circuit is normal.
Also be provided with the user profile storage among the described SHLR and search module, be used to store correspondence relationship information between Subscriber Number and the IGW/ VLR Visitor Location Register, arrive the IGW/ VLR Visitor Location Register at user place according to user's number searching.
Also be provided with the virtual circuit release module among the described LS, be used for after receiving called roaming number, being released to the virtual circuit resource of obtaining roaming number and taking.
The invention provides in a kind of intelligent home location register system the method that realizes that speech channel is optimized, the operating process that the common fixed network user of a kind of embodiment of described method calls out PHS (personal handyphone system) user comprises following operating procedure as shown in Figure 4:
Step 1: the fixed network user at first utilizes the calling of the virtual circuit initiation of foundation in advance to PHS user;
Before call out initiating, set up module by virtual circuit in advance and set up virtual circuit between PHS and the SHLR, and guarantee that by the virtual circuit management module state of described virtual circuit is normal;
Described virtual circuit does not carry out actual connection, does not connect actual transfer resource, does not therefore take equipment relay resource and transfer resource;
When the fixed network user called out PHS user, fixed switch LS sent the IAM message that carries called number and virtual circuit identifier to SHLR;
Module is stored and searched to user profile among the step 2:SHLR according to the called number of storage in advance and the corresponding relation of IGW (Interworking GateWay)/VLR (VLR Visitor Location Register), determine the IGW/VLR at called number place, and initiate called MS RN (roaming number) request to corresponding IGW/VLR;
Described called MS RN request is by MAP_PROVIDE_ROAMING_NUMBER message;
Step 3: the IGW/VLR at called subscriber place distributes MSRN to feed back to SHLR;
The message of described feedback sends to SHLR with the MAP_PROVIDE_ROAMING_NUMBER_Ack form;
After step 4:SHLR receives the MSRN of described distribution, return to caller LS by REL message;
Step 5: described LS responds RLC (Radio Link control) message and finishes and take out stitches;
That is, LS responds SHLR with RLC message and has received MSRN after receiving MSRN message, and the virtual circuit release module discharges the LS of said process use and the virtual circuit between the SHLR simultaneously;
Step 6: the LS at caller place carries out route reselection according to the above-mentioned MSRN that obtains, and routes the call on the IGW/VLR at called subscriber place;
Carry calling number and called roaming number in the IAM message that this calling procedure sends;
Step 7:IGW/VLR is according to the called MSRN of Incoming, to called initiation paging, treats call establishment after the called transmission response ACM message.
In sum, the invention solves the situation of speech channel and transmission resource waste in the overlay network mode, reduced the investment and the maintenance cost of operator.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
