Method for mobile terminal access network and anchor point management apparatus

Abstract

The invention discloses a method for a mobile terminal to access a network through some embodiments. The method comprises the steps as follows: a mobile management entity receives a request for establishing channel connection from the mobile terminal; and the mobile management entity establishes channel connection according to anchor point information obtained from an anchor management entity. The invention further provides anchor point management equipment, which comprises a first unit and a second unit used for saving and maintaining the address information of a local anchor point; the second unit is used for interaction with the mobile management entity, and the local anchor point and / or a mobile anchor point to acquire the information of the local anchor point and register with the first unit. The method and the device can optimize the process of establishing the mobile terminal during the system switch; and through acquiring a registered local anchor point which is the same as the local anchor point before the switch, the usability of the local anchor point is guaranteed and the speed of switch of the mobile terminal among systems is increased.

Description

technical field [0001] The present invention relates to a method for accessing a network, in particular to a method for a mobile terminal to attach to a network, switch a network, and update a network route based on anchor record information; the present invention also relates to an anchor management device, in particular to a method for using The invention relates to a server device for recording a mobile anchor point; it belongs to the technical field of mobile communication. Background technique [0002] With the emergence of the concept of broadband wireless access, wireless access technologies such as Wireless Fidelity (Wi-Fi for short) and Worldwide Interoperability for Microwave Access (WiMAX for short) develop rapidly. In contrast, Wideband Code Division Multiple Access (WCDMA for short) / High Speed ​​Downlink Package Access (HSDPA for short) / High Speed ​​Uplink Packet Access Although high speed uplink packet access (hereinafter referred to as: HSUPA) has great advan...

Problems solved by technology

[0014] For different access networks, the aforementioned existing technical solutions can ensure that the anchor point of switching between the aforementioned various or different systems—the data packet gateway PDN GW remains unchanged before and after the switching, to a certain extent However, in the case of roaming, when the mobile terminal UE switches between different systems, for example: when switching from a Non-3GPP system to a 3GPP system, the local anchor Serving GW acts as a Non- 3GPP accesses the anchor point of the Evolved Packet System (EPS for short) (EPS is the renaming of SAE by 3GPP), when the mobile terminal UE attaches to the 3GPP network, it needs to rebuild the data packet gateway PDN GW to the mobile terminal All bearers of the UE, therefore, the handover process will involve the reselection of the local anchor Serving GW and the re-establishment of the local anchor Serving GW to the data packet gateway PDN GW bearer, which makes the delay of system handover very large
