Description
Technical field
The present invention relates to communication technical field, particularly a kind of implementation method of CS business and equipment.
Background technology
With TD(Time Division, time division synchronous)-SCDMA(Synchronous Code Division Multiple Access, code division multiple access) for the G mobile communication of representative is in the extension process in market, Virtual network operator, TD user are in the face of a problem being difficult to avoid, and that is exactly that the burst of miscellaneous service demand and the epitonic contradiction of Radio Resource highlight day by day.Speech business user feels that speech quality is poor, Internet user feels that networking speed is slow, and user's total satisfactory grade is not high.Under forth generation mobile communication system is ripe and large-scale application still has the overall background in time, ripe WLAN(Wireless Local Area Network, WLAN (wireless local area network)) technology as alleviating the effective way of this contradiction, by the accreditation of increasing operator with receive.
As the useful supplement that TD-SCDMA covers at hot zones, by WLAN access technology, TD-SCDMA network is utilized to carry out PS(Packet Switching, packet switching) integration program of domain data service is comparatively ripe and be applied gradually.But under WLAN technology, utilizing TD-SCDMA network to carry out CS(Circuit Switching, circuit switching) scheme of territory business is also fewer.
At present, by WLAN access technology, to utilize TD-SCDMA network to carry out comparatively perfect in the scheme of CS territory business be UMA(Unlicensed Mobile Access, unauthorized mobile access) technology.This technology by 3GPP(Third Generation Partnership Project, 3G (Third Generation) Moblie Partnership Program) its R6 release protocol receive, rename GAN(Generic Access Network as, general access network) technology.
As shown in Figure 1, be the network topology structure schematic diagram of GAN in prior art.
Be not difficult to find out, the 3 G mobile communication network structure that the topology of GAN and 3GPP define is very similar.The advantage of such definition is, the change of this kind of structual shield Access Network access way, reduces the impact of different access technologies on core net to greatest extent.
In GAN architecture, original cellular network does not adjust, the network entity GANC(GAN Controller that just introducing one is new in a network, GAN controller).
The effect of GANC is equivalent to UTRAN(UMTS Terrestrial Radio Access Network, UMTS land radio access web; UMTS, Universal Mobile Telecommunications System, universal mobile telecommunications system) RNC(Radio Network Controller in original Access Network, radio network controller), be responsible for the RRM, link management, user management etc. of GAN network.In addition GANC also needs and the network entity exchanging user information in core net, the corresponding business service of completing user.Wherein, the network entity in core net comprises MSC(Mobile Switching Center, mobile switching centre), SGSN(Serving GPRS Support Node, GPRS serving GPRS support node; GPRS, General Packet Radio Service, general packet radio service technology) etc.
In GAN scheme, centered by GANC, the details of various external interface as shown in Figure 2.In existing GAN scheme, in order to ensure that the interface between GANC and core net is stablized, i.e. the interface specification of at utmost multiplexing Iu-cs, GAN solution to AP(Access Point, access point) carried out clear and definite definition with the function of GANC.AP only does the supplier of access link technology, the function of the very similar RNC of GANC, not only need to carry out controlling to user and link information and manage, also will by the 3GPP Access Layer between terminal, Non-Access Stratum protocols signaling mutual, reaching user can access network, carries out the object of voice communication.The Iu-cs interface of GANC continues to use the definition of 3G protocol stack, by the collaborative work of Iu-cs interface control plane, service surface, comparatively simple CS business datum can be passed to core net and carry out transfer of data and charging.In order to complete the enforcement of the safety measure in the multimode terminal authentications such as WLAN and communication process, SEGW(Security Gateway is added specially in GANC, security gateway), SEGW can select AAA(Authentication, Authorization, Accounting according to user profile, checking, mandate, book keeping operation) server, to utilize existing 3GPP core net security mechanism to carry out the discriminating of user and network identity.
Utilize WLAN technology to carry out CS service communication by TD-SCDMA network at present, comparatively ripe scheme is exactly the GAN solution that top is introduced.In this scheme, the AC(Access Controller in wlan system, access controller) that play the part of is exactly the such role of GANC.
Realizing in process of the present invention, inventor finds at least there is following problem in prior art:
Although the GAN technology in 3GPP is as by WLAN, carrying out the solution of CS service communication by TD-SCDMA network, is fairly perfect, still obviously there is shortcoming in actual application.
The first, according to GAN technology, the AC in WLAM system, just need to carry out huge function and interface transformation, the AC AP in WLAN combines the Access Network part becoming 3GPP network; The AP of WLAN is as just the supplier of physical link, and AC achieves the agreement flow process that 3GPP specifies, controls the foundation of user and business.Meanwhile, the interface between AP and AC is also similar with Iub interface.This series of change, can produce considerable influence to existing WLAN protocol function;
The second, according to GAN technology, WLAN multimode terminal in network just needs the consensus standard deferring to 3GPP definition, its high-level signaling needs to modify according to the description of 3GPP 44.318, need the Non-Access Stratum protocols of support 24.008 agreement simultaneously, this is for the WLAN chip solution of maturation, affect huge, beyond affordability.
In view of above 2 reasons, GAN technology carries out the solution of CS business as utilizing WLAN technology by TD-SCDMA network, although comparatively perfect, feasibility is not high.Therefore, in the network convergence process of WLAN and TD-SCDMA, no matter be CS territory business model or PS territory business model, all do not select GAN technology as solution.

Step S503, WLAN AP carry out dhcp address distribution.
Step S504, use USIM identity information, carry out authentication by 3GPP AAA and HLV object user.
Step S505, WLAN AC preserve the information of user.
Step S506, between TD-SCDMA/WLAN multimode terminal and WLAN AC, before transfer of data, signaling data transmits.
Effective information is passed to protocol conversion entity by step S507, WLAN AC.
Step S508, organize the response signaling of terminal and set up Iu-cs signaling.
Step S509, simulation set up terminal contexts, trigger Iu-cs interface sets up service bearer.
Step S510, terminal signaling carried out to response with mutual, set up the data path of terminal and AC.
In step S511, wlan system, CS business data transmission, protocol conversion entity seals off dress to CS data according to the different message encapsulation of different systems, afterwards, in TD system, carries out CS business data transmission.
