Problems solved by technology

[0023] Although the above process can realize handover, considering that there are a large number of HeNBs and UEs often handover, if each handover is performed through the MME, it will bring a large processing burden to the core network side, and also reduces switching efficiency

Embodiment Construction

[0063] Aiming at the problems existing in the prior art, the present invention proposes a handover scheme in a mobile communication system, which can terminate the handover at a gateway, thereby reducing the processing burden on the core network side and improving handover efficiency. The scheme of the present invention can have the following implementations:

[0064] (1) The MME located in the core network determines whether the handover can be terminated at the gateway, and sends the determination result to the gateway; when the gateway receives the message of handing over the UE, if the determination result indicates that the handover can be terminated at the gateway, the gateway follows the procedure for terminating at the gateway. The gateway completes the switching, and if it is determined that the gateway cannot be terminated, the gateway completes the switching in a manner that does not terminate at the gateway.

[0065] (2) The MME located in the core network sends th...

Abstract

The invention provides a switching method in a mobile communication system, comprising the following steps: for instance, a mobile management entity (MME) determines whether switching operation can be ended at a gateway and transmits a determining result to the gateway, when the gateway receives a message for switching user equipment (UE), if the determining result can be ended at the gateway, the switching operation can be carried out in a mode of ending at the gateway, and if the determining result can not be ended at the gateway, the switching operation can be carried out in a mode of not ending at the gateway; or the MME transmits UE position change report behavior and / or information report behavior of closed user group (CSG) to the gateway, the gateway determines whether the switching operation can be ended at the gateway according to the received content of the UE position change report behavior and / or the report behavior of the CSG, if so, switching operation is realized in a mode of ending at the gateway, and if not, the switching operation can be carried out in a mode of not ending at the gateway. By adopting the scheme, the handling burden of a core network side can be effectively reduced and the switching efficiency is improved.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a handover method in the mobile communication system. Background technique [0002] Long-term evolution (LTE) technology is an evolution technology of the third generation mobile communication system (3G), which has many advantages such as improving cell capacity and reducing system delay. [0003] figure 1 It is a schematic diagram of a composition structure of an existing LTE system. Such as figure 1 As shown, in the Evolved Universal Terrestrial Radio Access Network (E-UTRAN) of the LTE system, it mainly includes radio resource management entities such as a macro base station (eNB) and a home base station (HeNB), and further includes a home base station gateway ( HeNB GW); when the HeNB GW is not included, the HeNB can be directly connected to the mobility management entity (MME) in the core network; when the HeNB GW is included, the HeNB is connected to the MME through th...
