Problems solved by technology

However, APN belongs to the service layer technology, and the access network should not know the user's APN information; the management of APN is closely related to the operation strategy of the operator. When different operators share the access network, the RAN-Node can To select CN-Node, it is necessary to require RAN-Node to store the operation strategy and APN information of each operator. This approach is not in the interests of operators, because

Embodiment Construction

[0114] The core idea of ​​the present invention is: the wireless access network selects and attaches a core network node for the mobile station according to the routing information; the current core network node judges whether the mobile station needs to be transferred according to its own characteristics, and if not, the mobile station passes through The attached current core network node accesses the packet data network, and ends this process; if necessary, the current core network node determines the target core network node, and transfers the mobile station to attach to the target core network node, and the mobile station passes through the target core network node Access to packet data networks.

[0115] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

Abstract

This invention discloses a method for accessing packet data network (PDN), and a MS accesses packet data network by playing the core net of the network and the method includes: an access net selects CN-node for the MS and adheres it, the CN-node judges if needing transferring said MS according to its property, if not, said MS adheres itself on the CN-node and accesses the packet data net to finish the flow, if so, the CN-node determines a target CN-node and transfers the MS adhere to the target CN-node to access the packet data network by the target CN-node.

Description

technical field [0001] The invention relates to a mobile communication network access technology, in particular to a method for a mobile station (MS) to access a packet data network (PDN, Packet Data Network) through an evolved network (Evolved Network). Background technique [0002] Universal Mobile Telecommunications System (UMTS) is a third-generation wireless communication network technology standard defined by the Third Generation Partnership Project (3GPP), which released REL-99, REL-4, REL-5 and REL-6 Version. FIG. 1 is a schematic diagram of the network structure of the prior art UMTS. As shown in FIG. 1, the UMTS network consists of a core network (Core Network) and a UTMS terrestrial radio access network (UTRAN, UMTSTerrestrial Radio Access Network). The core network includes two parts, the circuit domain (CS, CircuitSwitch) and the packet domain (PS, Packet Switch), wherein the circuit domain provides services based on circuit switching such as voice services, wh...
