Paging method and equipment

Abstract

The invention discloses a paging method, access network equipment, core network equipment and UE.The paging method comprises receiving first paging information of paging UE sent by the core network, determining a paging community type of the first paging information, and sending second paging information of the paging UE to a community corresponding to the community type. The community type comprises an S-UMTS type and / or a traditional UMTS type. By the use of the paging method, the access network equipment, the core network equipment and UE, paging signling overheads can be reduced and paging efficiency can be improved.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a paging method, access network equipment, core network equipment and user equipment (User Equipment, UE). Background technique [0002] The uplink and downlink bandwidth of the traditional Universal Mobile Telecommunications System (UMTS) is 5MHZ. In order to improve the capacity of the uplink system, the uplink bandwidth of the system is divided into N (such as 2) subcarriers, and the bandwidth of each subcarrier is 1 / N (1 / 2) of 5MHZ. This system is called scalable UMTS (Scalable UMTS, S -UMTS) system. Different users can access different uplink subcarriers, and there is no uplink interference between different uplink subcarriers, thus improving uplink capacity. For example, when N is 2, the uplink uses 2.5MHZ, the downlink uses 5MHZ, the downlink transmission time interval (TransmissionTimeInterval, TTI) is 2ms, and the uplink TTI uses 4ms. This system is called as...

Problems solved by technology

[0006] When traditional UMTS cells and S-UMTS cells are deployed at the same time, when the core network sends a paging message to the access network to page traditional UEs in the idle state and UEs supporting S-UMTS, the network Targeted paging cannot be performed according to the capabilities of the UE, and the access network sends paging in all cells, which will cause unnecessary paging signaling overhead

For example, a traditional UE cannot camp on a cell of the S-UMTS system, and it is meaningless to initiate paging in a cell of the S-UMTS system, which will increase invalid air interface paging overhead

Since CSGID is a specific cell attribute of the HNB system, it cannot be used to solve the above problems
