Embodiment Construction

[0025] The embodiment of the present invention proposes a method, system and device for accessing the SAE core network. Through the SAE core network, a terminal accessing UTRAN is directly provided with an access service, and a default bearer is established for the terminal, thereby providing UMTS users with The always-on function is used to provide more services on the SAE network side.

[0026] The present invention will be described in detail below with preferred embodiments in conjunction with the accompanying drawings.

[0027] As shown in FIG. 2 , it is an architecture diagram of the network system in the embodiment of the present invention. It can be seen that the network system includes:

[0028] The UMTS access network (UTRAN) and the SAE core network connected to said UTRAN. A user terminal (MS, not shown) accesses the SAE core network through the UTRAN.

[0029] The SAE core network includes a Mobility Management Entity (MME), a Serving Gateway (Server SAEGateway...

Abstract

The example of the invention discloses a method for accessing system architecture evolution core network, which comprises that a mobility management entity in the system architecture evolution core network sends grouping data protocol context activation request to a universal terrestrial radio access network after network adhesion operation of the terminal which accesses the universal terrestrial radio access network after network is finished, and sends grouping data protocol activation flow process, in the activation flow of the grouping data protocol, the system architecture evolution core network creates default loading for the terminal which accesses the terrestrial radio access network of a universal radio communication system. The example of the invention relatively discloses a network system and a mobility management entity. The invention can create default loading for the terminal which accesses the terrestrial radio access network of a universal radio communication system, which provides a permanent on-line function.

Description

technical field [0001] The present invention relates to the field of system architecture evolution (System Architecture Evolution, SAE), in particular to a method, system and device for accessing the SAE core network. Background technique [0002] With the development of the SAE architecture system, operators will use SAE equipment to provide services in the future, so that users can enjoy better services. The current System Architecture Evolution / Long Term Evolution (SAE / LTE) architecture includes an LTE access network (eNodeB) and an SAE core network, where the SAE core network mainly includes a Mobility Management Entity (Mobility Management Entity, MME), Serving SAE Gateway (Serving SAE Gateway, S-GW) and Packet Data Network SAE Gateway (PDN SAE Gateway, P-GW). At the same time, in the transition process of this development, it is necessary to access the original 2G / 3G mobile network by using the SAE core network. However, in its current SAE architecture, the Serving G...
