Problems solved by technology

Under the existing typical configuration, the paging capacity of the control channel is about 207 times per second, but considering that a paging message needs to be sent in a large range such as a subnet, the paging capacity is still limited and it is difficult to adapt to the mobile Internet With the development of business, in campuses and other mobile Internet business hot spots represented by instant messaging (for example, Tencent QQ) business, the paging capacity is limited or tends to be limited, which cannot meet business needs

Abstract

The embodiment of the present invention discloses a method and a communication system for improving the paging capacity of the EVDO system, wherein the method includes: using the orthogonality of the Walsh codes corresponding to the MacIndex in advance, correspondingly assigning an unused MacIndex value to a new Increased control channels; the base station broadcasts the control channel information of multiple control channels through the air interface system message, and the multiple control channels include the newly added control channel; after receiving the control channel information, the user terminal uses the HASH function to calculate the number of control channels Perform HASH calculation with the IMSI of the user terminal to obtain the control channel that the user terminal should camp on and camp on; the base station controller BSC responds to the need to send a paging message to the user terminal, and uses the HASH function to compare the number of control channels and The IMSI of the user terminal performs a HASH operation to obtain the control channel where the user terminal resides, and sends the paging message of the user terminal on the control channel where the user terminal resides. The embodiment of the present invention can improve the paging capacity in the EVDO system.

Description

technical field [0001] The invention relates to communication technology, in particular to a method and a communication system for improving the paging capacity of an EVDO system. Background technique [0002] The Code Division Multiple Access 2000 Single Carrier Evolution Data (CDMA20001X EVDO, referred to as 1X EVDO or EVDO) system supports multiple users who are simultaneously active in the session. In order to distinguish different users, 1x EV-DO Rev. System A uses a 7-bit channel identifier (MACIndex) as the identifier of the user communicating with it or the identifier of the forward channel (MAC channel, traffic channel and control channel) to distinguish the user from the forward traffic channel. The handed-in Walsh codes correspond to each other one by one. The control channel and the traffic channel are time-division multiplexed. Forward media access control (MAC) channels are distinguished by mutually orthogonal Walsh codes, and there is a one-to-one mapping re...
