Abstract
The present invention discloses a method and a system for differentiating service grades and sending paging informayion. When a conversation establishment request of a calling terminal reaches a calling P-CSCF of a called terminal, an information combination device on the P-CSCF combines service type information of the calling with information of the conversation establishment request. The combined information is analyzed by an information analyzing device of the node when reaching a PDSN, an information packaging and sending device of the node transfers an IP package of the information of the conversation establishment request to a PCF, and simultaneously, an analyzed service type is informed. After obtaining the service type, a service type recognition device on the PCF informs a service type filling-in device to fill in an option, which represents the service type, in the service request information. An AN determines a sequence of sending paging information for the call according to the service type recognized in the service request information sent from the PCF. The scheme enables the AN to differentiate real-time and unreal-time services and preferentially send paging information of the real-time services.
Description
Technical field
The present invention relates to the IP Multimedia System (IMS, IP MultimediaSubsystem) in the mobile communications network, relate in particular to the method and system of distinguishing business grade transmission paging message in a kind of mobile communications network.
Background technology
Development along with internet and wireless traffic, the user improves for the requirement of wireless data service, when abundant business is provided quality of service is also had requirements at the higher level, the real commercialization of real-time multimedia business depends on system the end-to-end quality of service (QoS) of signaling plane, user's face is supported.
As the CDMA2000 network of one of 3D standard, the packet bandwidth of 153.6kbps can be provided for the user in more wide scope, arrive EV-DO during the stage when the CDMA2000 network development, user's grouping access rate will reach 2～4Mbps.HRPD (high rate packet data) Rev.A (HRPD Rev.A) system supports the transmission on the control channel to distinguish user class, preferentially sends the synchronically controlling information of advanced level user, asynchronous control information and sub-synchronically controlling information.But along with HRPD Rev.A system carries out real time business,, calling establishment time delay is had than higher requirement, therefore proposed how preferentially to send the beep-page message of real time business to improve the problem of user's impression as IP phone (VoIP), visual telephone (VT) etc.
The professional majority of VoIP, VT is the IMS framework that adopts dialogue-based initiation protocol (SIP, Session InitiationProtocol), by SIP register, call setup and control.
Fig. 1 illustrates an example of this network configuration.(AT) 101 that access terminal is connected to packet data serving node (PDSN, Packet DataServing Node) 104 by base station (BST) 102, base station controller (BSC) 103, links to each other by the R-P interface between BSC103 and the PDSN104.In the CDMA2000 network, PDSN104 bears grouped data access service function, and being connected between AT101 and the external data network is provided.PDSN104 enters the Internet by edge router (Edge Router) 105, simultaneously by media gateway (MGW) 106 accessing public switched telephone networks (PSTN).Wherein, the resource in the service quality territory (QoS territory) at its place of 105 management of edge router, the interface protocol between media gateway (MGW) 106 and the accessing public switched telephone network (PSTN) is a signalling system No.7.The IMS layer comprises a plurality of nodes, and these nodes are coupled to an IP backbone.Node shown in the figure is Proxy Call Session Control Function (P-CSCF) 108, service call conversation control function (S-CSCF) 109 in the local network and home subscriber server (HSS) 110, MGCF (MGCF) 107 and media gateway (MGW) 106 in the visit net.When the AT101 of Fig. 1 was called out by another AT, in order to set up session between two AT, the P-CSCF of suitable SIP signaling from the visit net that caller AT is connected sent to the S-CSCF in the local network at caller AT place.P-CSCF108 among the S-CSCF109 in S-CSCF contact and the local network that called AT101 is connected then, itself and then contact and visit net that called AT101 is connected.Then, with two PDSN that caller and called UE are connected respectively between call session set up.
Below, with reference to Fig. 2 prior art related to the present invention is described.
Fig. 2 is the call flow diagram of IMS portable terminal, and this figure selects from X.S0013-012 draft version 0.16.0.To being described as follows of step 201-204 wherein:
In step 201, service-call session control function (S-CSCF) is received foundation request (Invite) message of a session, and this message comprises initial SDP supplier information.The signaling paths that Invite message was set up according to when registration is forwarded to Proxy-Call Session Control Function (P-CSCF), and P-CSCF is forwarded to travelling carriage (MS) with Invite then.
In step 202, MS along this signaling paths return 183 sessions carry out in (183Session Progress) message, reply as initial SDP.
Step 203-204, P-CSCF may be with strategy and charging rule functions (PCRF) exchange application layer message, relevant QoS information of stream and/or charging principle information notification PCRF.Step 203 and 204 may be carried out simultaneously with step 202.
The subsequent step of this flow process and technical scheme of the present invention relation are little, are not illustrated at this.
As seen, the callee side flow process is that the SIP that calling terminal is initiated calls out the S-CSCF that is forwarded to called end by the S-CSCF of calling terminal, is forwarded to P-CSCF after the analyzing and processing.P-CSCF sends out the SIP signaling according to log-on message toward the packet data serving node (PDSN, Packet DataServing Node) at called accessing terminal (AT, Access Terminal) place.Data send to Packet Control Function (PCF by PDSN, PacketControl Function) after, send out the situation of paging for needs, be in resting state such as called AT, promptly terminal did not have to eat dishes without rice or wine to connect and was connected with A8 this moment, PCF sends A9-BS service request (A9-BS ServiceRequest) message toward AN, can carry service option (Service Option) field in this message, but, this field can be got default value SO64 (SO of HRPD system supplymentary link flow) because PCF can't know the type of service that packet is affiliated.Here the A8 connection of mentioning is the interface between access network (AN) and PCF.
P-CSCF just sends to PCRF with the QoS information of stream, again because PDSN does not resolve packet and directly transmits, so PDSN and AN can't be known concrete qos requirement before sending Invite to terminal called.
In existing called flow, the AN of called end sends out beep-page message toward called AT, and the AT response is also set up and eated dishes without rice or wine to connect, and the signaling message that receives application layer is afterwards just known type of service, be that AN can't know in advance that what business this is, can't preferentially send paging for real time business.When occurring control channel in the system when congested, the paging of real time business can't obtain priority treatment, causes calling establishment time delay very big, and user experience is not good.
