Description
Technical Field
The invention relates to a packet domain in mobile communication technology, in particular to a system and a method for realizing packet domain service access routing selection.
Background
The 3GPP packet domain services are numerous, different services need to access different service target networks, and different service access modes and routing modes need to be adopted. The 3GPP packet domain implements service routing by an Access Point Name APN (Access Point Name).
An APN consists of two parts, one is a network identifier identifying a target network to be accessed, and the other is an identifier of an operator, for example, as follows: internet, mncn000, mcc460, gprs, where internet represents that the target network that the user needs to access is internet network, and mncn000, mcc460, gprs represents that the operator is china mobile.
Generally, only a target network identifier part needs to be configured in a Mobile phone or an IMSI (International Mobile Subscriber Identity) card of a user, and an operator identifier part is complemented by an SGSN (Serving GPRS support Node). When the operator mark is supplemented, the SGSN analyzes the home operator information of the user from the IMSI number, and acquires the information of the roaming operator from the network configuration of the SGSN. An identifier for whether or not the subscriber is allowed to access from a roaming place is configured in the HLR (Home Location Register) of the subscriber. The user only needs to configure the network identification of the target network to be visited, and the selection of accessing from the GGSN (gateway GPRS support node) of the roaming place or from the GGSN of the home place when the user performs internet roaming of different operators can be realized by analyzing the operator identification by the SGSN and combining the identification of whether the user allows accessing from the roaming place.
Meanwhile, the GGSN configures, according to the APN, a mode of accessing to a corresponding Service Network, which needs to be adopted by a Service accessed by the APN, such as what VPN (Virtual Private Network) mode is adopted, whether RADIUS (Remote Authentication Dial In User Service) Authentication needs to be performed, which address allocation mode is adopted, and the like. And the GGSN selects a mode for accessing the service network according to the APN.
This way, a routing method based on service class is implemented to a certain extent, but as the APN used by the user needs to be configured on the user terminal, when the service class developed by the user is many, the terminal configuration is complex and the service use is difficult. Meanwhile, the routing mode based on the APN has flexibility, and is not convenient to popularize in other packet networks.

by the method, the optimal path selection and the policy routing control of service access can be provided for different services of different users, and the trouble that terminal configuration needs to be carried out by adopting APN is avoided.
The system realizes the service-based routing of the 3GPP PS architecture:

GGSN/REF (gateway GPRS support node, integrated with a routing policy enforcement function) is configured to receive a create traffic request and send a traffic routing policy request to a traffic routing decision function, where a REF logical entity may be deployed on GGSN.
The routing process based on the non-session service is shown in fig. 5:
step 501UE initiates a PDP activation context request to SGSN, wherein the request has service related identification such as APN;
step 502 after receiving PDP activation context request, SGSN initiates a request for creating PDP context to GGSN/REF, the request contains user identification IMSI and service related identification APN;
step 503, after receiving the request for creating the PDP context, the GGSN/REF executes the processes 203 to 207 in fig. 2, and acquires policy routing information such as a service available route and an access mode;
step 504, the GGSN/REF allocates a corresponding IP address to the user according to the acquired policy routing information, creates a user context and establishes an association relation with the policy routing information, and then the GGSN returns a PDP context response to the SGSN, and carries the IP allocated to the user in the response;

step 604, the UE starts to transmit IP packets, and the GGSN/REF guides the transmission of user data packets according to the obtained service routing strategy.
The SAE architecture is realized based on the service routing selection:
SAE (System Architecture Evolution), a System Architecture currently being researched by the 3GPP standardization working group to replace the current 3G PS, can provide higher transmission rate, shorter transmission delay, optimize grouping, and support mobility management between E-UTRAN (Evolved UTRAN), UTRAN, WLAN (Wireless Local Area Network), and other non-3 GPP access networks than the current PS core Network.
A schematic diagram of such a system architecture is shown in fig. 7.

IASA (Inter Access System Anchor, Anchor Point across multiple Access systems): one of the data gateways in the network, which is different from UPE, is that the IASA gateway is responsible for the global allocation of IP addresses and serves as a switching anchor between different access systems, including between 3GPP and non-3 GPP access systems.
The system framework of the invention based on the service routing is used for the SAE architecture, and the routing process based on the non-session service is shown in FIG. 8:
step 801UE initiates a service tunnel establishment request to MME, wherein the message has a service identifier;
step 802, after receiving a service tunnel establishment request, the MME sends a service tunnel establishment request to the UPE/REF, and the message carries a user identifier (such as IMSI) and a service identifier;
step 804, the UPE/REF allocates an IP address to the user according to the acquired information, associates the service route with the user context, and returns a service tunnel creating response to the MME, wherein the response contains the user identifier, the service identifier and the IP address allocated to the user;
step 805, after receiving the response of creating the service tunnel, the MME replies to the UE with a service tunnel creation reception message, where the message carries an IP address assigned to the user;
step 806, the UE starts sending data to the UPE/REF, and the UPE routes the data correctly according to the obtained service routing information.
The routing process based on the session service is shown in fig. 9:
step 901 SIP session interaction is performed between the UE and the AF, and the information contains the user identifier:
step 903RRF issues the service between the original IASA and UPE/REF along with the user identification and the service identification;
step 904, the UPE/REF initiates a user service tunnel creation process to create a service channel among the UE, the UPE and the IASA;
step 905UE sends data to UPE, UPE and IASA forward data according to the service routing policy.
