Embodiment Construction

[0022] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Usually, during the attachment, location update or handover process, the MEE is responsible for selecting the serving SGW and PGW for the UE.

[0024] 1. Select SGW

[0025] The MME supports a network-based topology to select an available SGW for the UE. In the overlapping area of ​​SGW services, the selection of SGW should reduce the possibility of SGW change, and also need to consider the load balance among S-GWs.

[0026] Usually, the MME selects the SGW according to the TAI area served by the SGW and the TAI where the UE is currently located. When the selection result is a group of SGWs, the MME selects the SGWs according to the round selection policy, so as to realize the load sharing of the SGWs. For example, when ...

Abstract

The embodiment of the invention provides a method and device for selecting network cell equipment. The method is applied to a miniaturized core network, and comprises the following steps: reading a valid record of an equipment table when selecting the network cell equipment; and determining the selected network cell equipment according to the valid record. When the network cell equipment needed tobe selected is the equipment of the miniaturized core network, the selection of the network cell equipment can be finished through the valid record in the equipment table without matching with TA andAPN information, thereby simplifying the selection process of the network cell equipment; the TA and APN information are unnecessary to configure in the configuration, namely, the configuration process can be simplified.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method for selecting network element equipment and a device for selecting network element equipment. Background technique [0002] Under the LTE (Long Term Evolvement, Long Term Evolution) network architecture, the wireless communication system is composed of a radio access network and a core network (Evolved Packet Core, EPC). Among them, in the actual networking of the core network, there may be multiple devices such as Mobility Management Entity (MME), Serving Gateway (ServingGateWay, SGW), Packet Data Network Gateway (Packet Data Network GateWay, PGW), etc. A network entity may need to discover or rediscover and select a different network node during initial attachment, handover, or tracking area update (Tracking Area Update, TAU) of a user equipment (User Equipment, UE). [0003] There are many users of EPC devices on the public network, such as tens ...
