Problems solved by technology

For a connected terminal that has ongoing services, if the timer expires, the evolution system will directly cut off the terminal's connection to the network, which will greatly reduce the user's perception and experience, which is not conducive to the operator's customer maintenance

Embodiment Construction

[0046] The present invention will be described in detail below with reference to the accompanying drawings.

[0047] The internal subscriber group (CSG) cell is the cell of the home base station. Because of its small coverage, it is also called a micro cell (also called a pico cell). It corresponds to a macro cell, that is, a cell covered by a macro base station, CSG Cells generally provide hotspot coverage within the geographical range of macro cells to absorb traffic and provide users with exclusive services. When network conditions permit, migrating terminals in the current CSG to base stations not belonging to the current CSG is a better solution for both users and operators. Based on this, the basic idea of ​​the present invention is: when the timer expires, the evolved system notifies the home base station connected to the terminal to switch the terminal to another base station, and sends the switching reason to the home base station, so that the home base station can be...

Abstract

The invention discloses a terminal transfer method. The method of the invention comprises the steps that: a mobile management entity monitors the time of a terminal staying in a home base station which belongs to a current internal subscriber group; when the time of the terminal staying in the home base station exceeds the preset time threshold, if the terminal and the home base station are in a connection state, the mobile management entity sends a request of switching to the home base station which is connected with the terminal to request the terminal to be switched to a target base station and carries the identifier of the terminal in the request of switching. The invention also discloses a mobile transfer system and the mobile management entity. By adopting the invention, the terminal in the current CSG is transferred to a base station which does not belong to the current CSG, thus resulting in that the normal operation of subscriber services can be guaranteed; the perception and the experience of subscribers can be improved for benefiting operators to maintain customers.

Description

technical field [0001] The invention relates to the communication field, in particular to a mobile management entity and a terminal transfer method and system. Background technique [0002] In order to maintain the competitiveness of the third-generation mobile communication system in the communication field, and to provide users with faster speed, lower delay and more personalized mobile communication services at a lower operating cost, the third-generation partner A standard working group of a 3rd Generation Partnership Project (abbreviated as 3GPP) is working on research on an evolved system (Evolved Packet System, abbreviated as EPS). [0003] figure 1 It is a structural diagram of the EPS system. The EPS system is divided into two parts: Evolved Universal Terrestrial Radio Access Network (E-UTRAN for short) and Evolved Packet Core (EPC for short). Among them, EPC is also called System Architecture Evolution (SAE for short), such as figure 1 As shown, the EPS system i...
