Description
Technical field
The present invention relates to the communications field, particularly a kind of CS of returning back to sets up in the territory method, system and the relevant device of audio call.
Background technology
2G/3G (second generation mobile communication technology/3G (Third Generation) Moblie technology refers generally to GSM and WCDMA network) network can be regarded a kind of comprehensive covering as to a certain extent through for many years deployment.Nowadays, development along with technology, SAE/LTE (System Architecture Evolution/Long Term Evolution), HSPA (high-speed packet access), HSPA+ (high-speed packet access evolution) and WiMAX (micro-wave access global inter communication) network-covered are to some areas, like this, in present communication network, these networks and 2G/3G network are also deposited.For convenience of description, will only provide SAE/LTE, the HSPA in PS (packet switching) territory, HSPA+, WiMAX etc. to be referred to as pure PS territory network.
At different network carrying mechanism, the audio call of mobile communication can be divided into following several classes:
The first kind is the session service of CS (circuit commutative field) territory carrying, as voice call;
Second class is the session service of PS territory carrying, is also referred to as VoIP (Voice over IP technology) class business, provides OoS (quality services) to guarantee by IMS (IP multimedia service subsystem), as the voice call of IP carrying.
For pure PS territory network, audio call can only transmit in its PS territory carrying, and IMS controls audio call by IP-based network.In the 2G/3G network, audio call generally is to be carried on the CS territory.
The user who makes a call is in the call process, might cross over two networks, because the difference of load-bearing of mobile telecommunication business mechanism, cause moving out pure PS territory (as: SAE/LTE) network base station institute coverage when portable terminal, when entering the 2G/3G network base station area of coverage, the interruption of IMS audio call may occur, thereby influence the continuity that user speech is called out.
In order to address the above problem, guarantee the continuity that user speech is called out, adopt the three types of technology scheme at present, as follows respectively:
SRVCC (single Radio Link voice continuity) technical scheme, CS over PS (CS of PS carrying) technical scheme and Redirection (reorientation) technical scheme.
Wherein: the SRVCC technical scheme requires: dispose IMS; Need the gateway node or the network itself of the conversion of a responsible PS and CS signaling to support PS handover, DTM characteristic.
CS over PS technical scheme has eMSC scheme and Page in LTE at present, call in 2G/3G CS scheme.
Wherein eMSC (MSC of evolution) scheme requires to dispose eMSC (mobile switching centre of evolution).
Page in LTE, call in 2G/3G (LTE paging, 2G/3G set up calling) scheme triggers the renewal of LA based on the renewal process of TA/LA combination in the TA renewal process.The beep-page message of all called audio calls is all from the MSC of 2G/3G.This class beep-page message is forwarded to MME by MSC, and is issued to eNB by MME again, and eNB also no longer continues to issue, but by PS handover it is switched to the 2G/3G network, sets up in the CS territory of 2G/3G network and calls out.
Scheme after Page in LTE, call in 2G/3G advance requires: network support PS handover and DTM; The mapping relations that TA/TA list and LA are limited, promptly TA/TA list can not cross over the LA of two and plural MSC administration.In the early deployment stage of LTE, IMS may not dispose, and most GSM networks are not supported PS handover and DTM.And the limited mapping relations of TA/TA list and LA have limited the flexibility that LTE disposes.For this reason, proposed a kind of audio call solution that does not rely on above-mentioned constraints, return back to the CS territory support of SAE/LTE early deployment stage to audio call is provided.And, adopt called roaming retry technology (MT roaming retry call), solved the problem that TA/TA list and LA can not realize overlapping covering fully.
Summary of the invention

Embodiment
The purpose of the invention process profit is: when portable terminal was in the LTE network coverage, portable terminal used virtual LA to the registration of CS territory, thereby when guaranteeing that portable terminal resides in the LTE network, portable terminal still can receive the audio call in CS territory.
Specifically, when portable terminal resides in the LTE network, the approximate zone that is equal at the LA of same physical location 2G/3G, virtual LA (lane place) zone.Because the LA of 2G/3G is made up of the 2G/3G sub-district, and for forming by the LTE sub-district in the virtual LA zone of LTE network, so when portable terminal resided in the LTE network, the LA zone of being made up of the 2G/3G sub-district in virtual LA zone of being made up of the LTE sub-district and same position zone was not exclusively overlapping.
When portable terminal resides in the LTE network, select a MSC (mobile switching centre) according to the virtual LA zone of forming by the LTE sub-district.But portable terminal return back on the 2G/3G sub-district, and this 2G/3G sub-district may belong to another one LA, thereby portable terminal may be selected another MSC.
Whether need MSC upgraded to support MSC transmission to the audio call beep-page message of MME (mobile management entity), two kinds of schemes of option A and option b can be arranged if depending on.Option A need be to the MSC upgrading to support sending the audio call beep-page message to MME.Option b increases a Mobility proxy (the logic function body of mobility agent) logic function body and be responsible for transmitting LA renewal and audio call beep-page message between MSC and MME.
Angle from MSC, Mobility proxy is a BSS/RNS (base station sub-system/infinite network subsystem), all and TA/TAlist exist the LA of mapping relations to comprise this BSS/RNS by Mobility proxy simulation, and these TA/TA list belong to the MME that is connected with this Mobility proxy.By configuration LA, add this BSS/RNS by Mobility proxy simulation, MSC can carry out the renewal of LA and send the audio call beep-page message according to the flow process of standard.If portable terminal wants gravity treatment to set up called audio call to the 2G/3G sub-district, then need to transmit the audio call beep-page message by these two kinds of schemes, if portable terminal wants gravity treatment to set up the caller audio call to the 2G/3G sub-district, then do not need above-mentioned two schemes to transmit the audio call beep-page message.The system architecture of these two schemes is respectively as Fig. 1, Fig. 2.
The method of concrete configuration all exists TA/TA list and the LA corresponding with it for each LTE sub-district, the BSS/RNS that each will all comprise this Mobility proxy simulation by the LA that Mobility proxy upgrades does not revise the gsm protocol standard like this and can realize that LA upgrades and the audio call beep-page message arrives portable terminal through the LTE forwarded.Interface between Mobility proxy and the MME is S3 ' (the S3 interface of simplification, only transmitting LA upgrades and beep-page message), when portable terminal (terminal) switches from the SAE/LTE network to the 2G/3G network or when switching from the 2G/3G network to the SAE/LTE network, all switching message are all passed through Mobility proxy, and Mobility proxy is always on the path of S3 ' interface.In addition, the interface between Mobility proxy and the MME also can be similar GS ' (Gs like, the Gs interface of simplification only transmit LA and upgrade and beep-page message) interface.
For convenience of description, define two logic entity: VMSC-R, VMSC-S, wherein:
VMSC-R promptly registers VMSC (registration Visited Mobile Switching Center), and portable terminal is updated in this VMSC (Visited Mobile Switching Center) at the last LA of LTE network.
VMSC-S promptly serves VMSC (voice call service Visited Mobile Switching Center), and audio call was by this VMSC (Visited Mobile Switching Center) foundation and as anchor MSC (grappling MSC) after the 2G/3G sub-district was arrived in the portable terminal gravity treatment.
The cell change of network enabled control (comprise towards the CS territory, hereinafter except that specified otherwise, all comprise the CS territory) can be by the system information or the dedicated signaling notice portable terminal of broadcasting for the LTE network.The method of the system information notice by broadcasting makes the cell change of all portable terminals in the sub-district all by network control.Adopt the mode of dedicated signaling,, can realize notifying the cell change of specific portable terminal all by network control as switching message, measuring control messages, cell change/updating message, beep-page message etc.
