Description
Technical field
The present invention relates to the mobile communication technology field, the mobile communication network framework that especially relates to a kind of evolution in the third generation mobile system reaches under this network system architecture, and its terminal is to the method for the CN of evolution registers kernel network.
Background technology
In order to guarantee the competitiveness of 3GPP system in following 10 years down to the time more of a specified duration, the work of an access technology evolution is just carried out at the 3GPP organization internal.Particularly, in the 3GPP system, use group technology to need further to strengthen in order to strengthen the 3GPP system handles ability of the IP data service of growth fast.Most important several sections comprises in this class technology evolution: reduce time delay, Gao Su user data rate more, the reduction of the power system capacity of enhancing and coverage and operator's integral body cost.And the network configuration of evolution also is an important index for the backwards compatibility of existing network.
Several key elements that the network architecture of evolution need satisfy are:
At the initial phase of accessing terminal to network, basic IP connects and need set up in the network of evolution;
The network architecture of evolution must minimize the time delay of user data;
The definition of each functional module should be avoided the overlapping or repetition of function in the evolution network framework, to avoid unnecessary signaling interaction and time delay.
In the existing UMTS system configuration, the structure of user data plane makes the transmission of user data need pass through Gateway GPRS Support Node GGSN (Gateway GPRS Support Node), Serving GPRS Support Node SGSN (Serving GPRS Support Node), UMTS Terrestrial radio access network UTRAN (UMTS Terrestial Radio Access Network) ability incoming terminal, and such time delay that produces is considerably beyond the desired time delay of network of evolution.
In addition, in original UMTS system, the attaching process of general packet radio service gprs (GeneralPacket Radio Service) and the contextual activation of packet data protocol PDP (Packet DataProtocol) are two separating process.After start, terminal can be carried out a GPRS attaching process, wherein mainly is an authentication process.And after adhering to, terminal did not have IP to connect before activating PDP Context.Have only when selected Network Access Point and by SGSN when GGSN initiates the PDP context activation request, terminal just can be provided an IP address and corresponding configuration parameters.It is elongated to cause the user to initiate professional time delay like this, and the requirement of this process and evolvement network obviously is not inconsistent, so the network configuration of evolution needs new architecture and register flow path to reach the minimized needs of time delay.
At present, the terminal that defines among the 3GPP carry out GPRS adhere to the flow process of PDP context activation as shown in Figure 1:
1. terminal is adhered to request by UTRAN to SGSN initiation GPRS;
2. finish safety functions such as authentication, authentication;
3.SGSN initiate position updating request to hierarchical service system HSS, and obtain user signing contract information from HSS;
Adhere to request acceptance 4.SGSN send GPRS to terminal;
5. finishing GPRS adheres to;
6. terminal initiates to activate the PDP Context request to SGSN;
Set up request 7.SGSN initiate PDP Context to GGSN; GGSN or insert Radius (Remote Access Dial in User Service) server by the far-end dial-in user service and carry out authentication and address assignment, perhaps adopt Radius to carry out authentication and dynamic host configuration protocol DHCP (Dynamic Host Configuration Protocol) and carry out one of these two kinds of methods of address assignment and give IP address of terminal distribution, the PDP Context of GGSN response is afterwards set up request;
8. the radio bearer between terminal and UTRAN is set up;
9.SGSN send PDP Context update notification GGSN, GGSN accepts and confirms;
(this signaling has only when other reduction of wireless QoS level, can not satisfy the QoS level special talent triggering that the PDP Context the inside requires)
10.PDP context activation is finished.
In addition, network also can be initiated the PDP context activation request, and Fig. 2 is a network activation PDP Context process, as shown in Figure 2:
1.GGSN receive the rules data cell PDP PDU (Protocol Data Unit) of a packet data protocol;
2.GGSN the PDP activation of network requests is initiated in decision, and sends the GPRS routing iinformation to obtain the relevant SGSN information of pdp address to HSS.HSS sends GPRS routing iinformation confirmation to GGSN;
3.GGSN send PDU notice request information to corresponding SGSN.SGSN will to terminal request activate relevant PDP Context to GGSN to represent it by PDU Notification Validation information;
4.SGSN PDP Context is activated in the requesting terminal;
5. terminal enters pdp context activation.
From above Fig. 2 Fig. 3 is described as can be known, in the prior art GPRS adhere to PDP context activation be two independently flow processs, like this, when a business is come, if there is not already present PDP Context, terminal must be carried out the PDP context activation request and be finished session to obtain an IP address foundation carrying.Like this, the professional time delay of setting up will substantially exceed the desired maximum delay of evolvement network, and whole flow process has related to the mutual of a lot of signalings, has wasted the especially resource of air interface of a lot of Internet resources.
Summary of the invention
Main purpose of the present invention is by setting up a kind of mobile communication network framework of evolution, so that under the mobile communication network framework of this evolution, provides a kind of endpoint registration flow process of more optimizing.Adhere to and the PDP context activation flow process by the GPRS that merges terminal, make terminal after registration is finished, obtain a PDP Context of an IP address and acquiescence at once, like this when the session of terminal originating service or response to network initiation, the setup delay of session shortens greatly, and, by simplifying flow process, optimized the mutual of signaling, the resource of having saved network greatly.
Purpose of the present invention is achieved through the following technical solutions:
The present invention proposes a kind of mobile communication network of evolution, mainly comprise the CN core net of evolution and the UMTS Terrestrial radio access network of evolution, it is characterized in that also comprising a connecting system gateway function modules A SGW, it provides being connected of mobile communication network and external data network, finish the access and the transmission of user data service, when terminal is being initiated register flow path,, and distribute an IP address for described terminal is set up a carrying to ASGW; With a mobile management functional module E-MM who strengthens, registration and session information that its management is relevant with terminal with preservation, the office terminal in roaming between the different access networks and the mobile management within E-UTRAN.
