Paging method, device and base station of cluster communication

Abstract

The invention discloses a paging method of cluster communication. The method comprises the following steps: a base station confirms paging period and paging period number N of sending paging message continuously and the base station sends the paging message on each paging period in the confirmed N paging periods. Correspondingly, the invention provides the paging device of the cluster communication, which comprises the base station for confirming the paging period and the paging period number N of sending the paging message continuously, informing a cluster group terminal of a time slot period index corresponding to the confirmed paging period and sending the paging message on each paging period in the confirmed N paging periods. The cluster group terminal is used to confirm the minimum monitoring period and hash monitoring time slot within the minimum monitoring period, monitors a paging channel on the monitoring time slot and receives the paging message sent by the base station. The invention further provides the paging base station of the cluster communication. The invention can monitor the cluster group terminals with different monitoring periods.

Description

technical field [0001] The invention relates to the field of trunking communication, in particular to a paging method, device and base station for trunking communication. Background technique [0002] Because the minimum paging cycle of the trunking communication system based on Code Division Multiple Access (CDMA, Code Division Multi Address) technology is generally 16 time slots, the time length is 1.28 seconds, that is, only one paging message is sent within 1.28 seconds, so , resulting in a too long connection time for some trunking group terminals to perform trunking group paging, which is far from meeting the requirements for fast access to trunking group paging. Therefore, in order to enable fast access of the trunking group paging, a negative time slot paging cycle is implemented in the trunking communication system, so as to shorten the connection time of the trunking group paging. [0003] However, some current trunking group terminals no longer support negative t...

AI Technical Summary

Problems solved by technology

[0003] However, some current trunking group terminals no longer support negative time slots, so there are two types of trunking group terminals that support negative time slots and those that do not support negative time slots in the current network, even in the same trunk call group There may also be two types of cluster group terminals that support negative slots and those that do not

Then, if the base station is still paging according to the negative time slot method, there may be a problem that some called trunking group terminals cannot be connected

Specifically, if the base station also sends paging messages according to the paging cycle of negative time slots, for example: continuously sending paging messages according to 8 time slots, and the cluster group terminals that do not support negative paging cycle monitoring, then the trunking group terminal monitoring time slot 0 to time slot 7 can receive the paging message, but the trunking group terminal monitoring time slot 8 to time slot 15 cannot receive the paging message, so negative time is not supported There is a 50% probability that the trunking group terminals in the gap will not receive the paging message, resulting in missed calls
