Description

The motion management method of voice conversation and device

Technical field

The invention belongs to moving communicating field, relate in particular to a kind of motion management method and device of voice conversation.

Background technology

Universal mobile telecommunications system (Universal Mobile Telecommunications System, abbreviate as: UMTS) be to adopt Wideband Code Division Multiple Access (WCDMA) to insert (Wideband Code Division Multiple Access, abbreviate as: the WCDMA) 3-G (Generation Three mobile communication system) of air interface technologies also calls the WCDMA communication system to UMTS usually.UMTS has adopted and the similar structure of second generation mobile communication system, comprise wireless access network (Radio Access Network abbreviates as: RAN) and core net (CoreNetwork abbreviates as: CN).Wherein, wireless access network is used to handle all and wireless function associated, and CN handles functions such as customer location management in the UMTS, service management and the exchange of realization and external network and routing function.CN from be divided in logic circuit commutative field (Circuit Switched Domain abbreviates as: CS) and packet-switched domain (Packet Switched Domain abbreviates as: PS).(Universal Terrestrial Radio Access Network abbreviates as Universal Terrestrial Radio Access Network: UTRAN), (User Equipment abbreviates as: UE) constituted UMTS together for CN and subscriber equipment.In order to improve systematic function, carrying out system's architecture evolution (SystemArchitecture Evolution, project SAE) at present in the world.SAE has roaming framework and non-roaming framework, and SAE provides a kind of packet transmission networks relatively efficiently for the user, can (Voice over Intemet Protocol abbreviates as: VoIP) business for the user provides internet protocol voice.

With non-roaming scene is example, and the SAE framework is described.

Fig. 1 is existing based on non-roaming SAE configuration diagram.As shown in Figure 1, UE is subscriber equipment, i.e. terminal; EUTRAN is that (Evolution UniversalTerrestrial Radio Access Network abbreviates as: EUTRAN), the NodeB of evolution is arranged in the Universal Terrestrial Radio Access Network of evolution, be called ENodeB for the Universal Terrestrial Radio Access Network of evolution.Though in EUTRAN, may also have other nodes, replace these nodes with ENodeB for the ease of understanding.MME be Mobility Management Entity (Mobility Management Entity abbreviates as: MME), have the chain of command function, as with the chain of command Message Processing of UE, mobile management (record UE positional information), paging and authentication etc.ServingSAE Gateway is service SAE gateway (Serving System Architecture EvolutionGateway, abbreviate as: Serving SAE Gateway) have user plane functions, transmit the data of UE, and between the wireless access network of evolution S1-U interface is arranged.MME and Serving SAE Gateway are similar to traditional Serving GPRS Support Node altogether, and (Serving General Packet Radio ServiceSupport Node abbreviates as: SGSN).PDN SAE Gateway is the SAE of Packet Data Network gateway (Packet Data Network System Architecture Evolution Gateway, abbreviate as: PDNSAE Gateway), be similar to traditional webmaster GPRS Support Node (Gateway General PacketRadio Service Support Node, abbreviate as: GGSN), and the SGi interface is arranged between the external data network, and Packet Data Network's SAE gateway has functions such as strategy execution, packet filtering.PCRF is that (Policy and Charging Rules Function abbreviates as "Policy and Charging Rules Function: PCRF), realize and the policy-related (noun) controlled function.The S3 interface is the interface between the SGSN of MME and 2G/3G, and (GPRS Tunnelling Protocol abbreviates as: GTP) this interface based on GPRS Tunnel Protocol.The S4 interface is the interface between service SAE gateway and the SGSN.Service SAE gateway may be positioned at same physical node with the SAE of Packet Data Network gateway and also may be positioned at different physical nodes.MME may be positioned at same physical node with service SAE gateway also may be positioned at different physical nodes.When top logic entity is positioned at same physical node, then to transfer the speech business of internal node message to be the important source of profits of telecom operators to the interface signaling between it, following also is trend of the times to Long Term Evolution (Long Time Evolution is called for short LTE) or the deployment of SAE.Scheme of the prior art is that (Single Radio Voice Call Continuity between IMS and CS abbreviates as: SR-VCC) scheme and circuit commutative field feedback (CS Fallback) for voice continuity between single-receiver IMS and the CS.

A kind of GAN-like framework is proposed at present with carrying CS speech business on the packet-switched domain that is implemented in evolution, use universal access network (Generic Access Network, abbreviate as: thus GAN) framework can be reused the CS net and realizes VoIP over LTE, and (IPMultimedia Subsystem abbreviates as: IMS) network not need to dispose IP Multimedia System; Strengthen the handover mechanism of GAN simultaneously by the SR-VCC handover mechanism.

Fig. 2 is existing GAN-like configuration diagram.As shown in Figure 2, MSC/VLR (may comprise CS-MGW) belongs to circuit domain core net, SGSN belongs to packet domain core network, and the Universal Terrestrial Radio Access Network of Universal Terrestrial Radio Access Network and evolution is as Access Network, for the user provides access capability, providing basic signaling and medium to transmit passage for the user obtains business, is that the user obtains professional basis.

(the Mobile Switching Center of traditional mobile switching centre, abbreviate as: MSC) only support the access of circuit domain mode, do not support grouping to insert, because grouping inserts and inserts with circuit is two kinds of different access waies, if grouping be inserted is that MSC is used, coming provides professional for the user, a logic entity then logically need be set between gruping insertion network and mobile switching centre realize this function, this entity can (Generic Access Network Controller abbreviates as: GANC) for general access network controller.This module class is similar to BSS/RNS, and its major function provides the signalling path between UE and MSC, and UE is connected to GANC by the IP Access Network, and GANC is responsible for the data interaction of user's face and chain of command.General access network controller also includes media gateway, and (Media Gateway abbreviates as: MGW) function, conversion is based on speech coding and the IP-based speech coding of 2G CS.From the angle of implementing, this logic entity can be melted among the MSC, also can individualism, even can be melted in the gruping insertion network.

The inventor finds: the scheme of carrying the CS speech business by the GAN-like framework on the packet-switched domain of evolution does not have the corresponding mobile administrative mechanism at present.Therefore up to the present, UE still can't obtain business from 2G/3G CS territory by the LTE/SAE network, such as carrying out VoIP, data service and other circuit domain supplementary services.

Motion management method second execution mode of voice conversation

The scene that the subscriber equipment that ought carry out voice conversation is positioned at the LTE/SAE gruping insertion network and inserts 2G/3G CS network by target GANC is below described.Switch main body this moment can be subscriber equipment, also can be Mobility Management Entity (Mobility Management Entity abbreviates MME as).The embodiment of the embodiment that switches main body and be MME when switching main body and be subscriber equipment is similar, and difference is that mainly handoff request message undertaken by the Sv interface between MME and the source GANC alternately.

Fig. 4 a is the route embodiment schematic diagram between subscriber equipment and the target GANC in the motion management method of the another kind of voice conversation of the present invention.Shown in Fig. 4 a, at first, subscriber equipment knows that LA changes, and passes through UP ' interface or Z1 interface (signalling path between UE and the source GANC) then and sends handoff request message (HO request message) to source GANC, and the voice conversation that triggers between GANC with notification source GANC switches.

This handoff request message is passed through UP ' interface or Z1 interface, through eNodeB, Mobility Management Entity and SAE gateway (SAE GW), is sent to source GANC.

Here, subscriber equipment passes through UP ' interface or Z1 interface and transmits handoff request message to source GANC.For example, UP ' interface or Z1 interface utilize the IP carrying of LTE/SAE, and utilize the external interface of packet data network gateway (PDN GW), and promptly the SGi interface is realized the transmission of handoff request message.Again for example, UP ' interface or Z1 interface utilize subscriber equipment and at NAS signalling path between the MME of LTE/SAE and the SV interface between MME and the GANC, realize the transmission of handoff request message.Be that example specifically describes with the implementation of utilizing the IP carrying in the following description, and adopt the implementation of NAS signalling path and SV interface and employing to utilize the implementation of IP carrying similar, do not give unnecessary details at this.

Classify from the angle of MSC, voice between GANC switch can be divided into two kinds, a kind ofly belongs to identical MSC for source GANC with target GANC; Another kind belongs to different MSC for source GANC with target GANC.Analyze from the GANC angle, source GANC adds in the handoff request message between handoff request message or MSC between BSC that to be used for this handoff request of notification target GANC be the indication that voice switch between GANC.For example, this indication can be added in transparent vessel (Transparent Container) field of handoff request message between handoff request message between BSC or MSC, and through the MSC transparent transmission to target GANC.If packet domain overlay area and overlay area, objective circuit territory do not belong to same MSC, then in above-mentioned handoff procedure, set up the relaying carrying that is used for the voice switching between source MSC and the target MSC.

Source GANC finds the method for target GANC that multiple implementation can be arranged.For example wherein a kind of mode is, subscriber equipment passes through UP ' interface or Z1 interface with the band of position (Location Area, abbreviate as: LA) (LA is the service range of MSC), tracing area (Tracking Area, abbreviate as: TA) (TA is the service range of MME) or ECGI send to source GANC, source GANC finds target GANC according to LA, TA or ECGI, switches with the voice that trigger between GANC thereby send handoff request message.For example another kind of mode is, subscriber equipment oneself is found the target GANC in new LA service, and pass through the identification information of UP ' interface or Z1 interface notification source GANC target GANC, switch with the voice that trigger between GANC thereby make source GANC send handoff request message.Wherein, the identification information of GANC is the identification information that is used to distinguish GANC, as the area information of target GANC, the virtual Cell-ID of target GANC, or is derived and identification information of coming or the like by arbitrary combination of LA, TA and ECGI.Incidence relation between virtual Cell-ID and this GANC can configured in advance in GANC, also can configured in advance in MSC or VLR.

Fig. 4 b is for setting up the schematic diagram of voice channel embodiment between subscriber equipment and the target GANC in the motion management method of the another kind of voice conversation of the present invention.Shown in Fig. 4 b, subscriber equipment sends the voice bearer negotiation information to target GANC, and this voice bearer negotiation information can be included in the handoff request message between GANC.This voice bearer negotiation information, promptly SDP offer information can comprise: IP address, port information and QoS relevant parameter etc.The voice bearer that this moment, target GANC carried out in the target area is consulted, and with negotiation result, promptly carries descriptor, returns to subscriber equipment through MSC and source GANC.The voice bearer negotiation information of subscriber equipment can send to source GANC when subscriber equipment sends handoff request message, and sends to target GANC again by source GANC; Also can source GANC send to target GANC according to the information of the subscriber equipment of having stored.

Wherein, the bearer negotiation that target GANC carries out the target area is meant: target GANC sends voice channel by Rx interface to the PCRF of SAE and sets up request, PCRF authorizes according to the voice channel request of setting up carrying out PCC rule, and the result sent to PDN GW and indicate described PDN GW to set up voice channel, PDN GW receives between voice channel foundation request back and the subscriber equipment and sets up voice channel, PCRF carries voice channel of descriptor and feeds back to target GANC, and target GANC carries voice channel of descriptor along with the switching command between GANC (HO command) process MSC, source GANC returns to subscriber equipment.At this moment, set up the voice dedicated bearer between subscriber equipment and the target GANC.

Fig. 4 c is for setting up the schematic diagram of signalling path embodiment between subscriber equipment and the target GANC in the motion management method of the another kind of voice conversation of the present invention.Shown in Fig. 4 c, except foundation is used for the voice channel of transmission medium, also need to set up a signalling path that is used between subscriber equipment and target GANC, transmitting signaling, promptly set up UP ' interface or Z1 interface between subscriber equipment and the target GANC.The method of setting up signalling path is similar to the method for setting up voice channel, switching message between GANC need comprise the signalling path descriptor of subscriber equipment, and the signaling bear of being carried out the target area by target GANC is consulted, to set up subscriber equipment to UP ' interface or Z1 interface between the target GANC.

The signalling path descriptor of the target area of carrying in the switching command message (HO command message) of subscriber equipment according to target GANC transmission inserts the target area, wherein comprises information such as radio bearer parameter and channel frequency in the signalling path descriptor of this target area.

Fig. 4 d is for switching the schematic diagram of embodiment between subscriber equipment and the target GANC in the motion management method of the another kind of voice conversation of the present invention.Shown in Fig. 4 d, eNodeB detects the access of UE, target GANC receives the VoP or the relevant signaling of subscriber equipment, and then target GANC sends handoff completion message (HO completed message) to source GANC, and this message is sent to source GANC through MSC.

Fig. 4 e discharges the schematic diagram of resource embodiment for source GANC in the motion management method of the another kind of voice conversation of the present invention.Shown in Fig. 4 e, when source GANC received the handoff completion message (HO completed message) that is sent by target GANC, source GANC discharged related resource.At this moment, voice channel and signalling path between subscriber equipment and the source GANC are released, thereby have finished the handoff procedure of the voice conversation between the GANC under the state of activation.

In the above-described embodiments, in order to guarantee the fail safe of signalling path and voice channel, subscriber equipment is in the handoff request message (HO request message) that target GANC sends, except the voice bearer negotiation information that comprises subscriber equipment, also comprise IP address, port information and QoS relevant parameter etc.At this moment, in order to set up the IP-Sec security mechanism, subscriber equipment can further carry corresponding security parameter, includes but not limited to the port information of subscriber equipment, as client and service end bidirectional port information etc.

Described target GANC carries out the bearer negotiation in targeted packets zone, and negotiation result (IP address, the port information equivalent-load descriptor SDP answer of the bearing resource that target GANC distributes) is returned to subscriber equipment along with the switching command between GANC (HO command) and through MSC, source GANC.In this message, target GANC also can provide security parameter to subscriber equipment, as the client port information of safe key, target GANC and service end port information etc.

By mutual security parameter between subscriber equipment and target GANC, and the safe key among subscriber equipment and the target GANC, just can set up safe passage between subscriber equipment and target GANC, the IP-Sec security mechanism was set up and was finished this moment.
