A method of inter-frequency switching for group calls in broadband trunking systems

Abstract

The invention discloses a method for solving pilot frequency switching of a group call in a broadband cluster system. The method comprises the following steps of step 1 setting a shared channel measurement GAP and a pilot frequency measurement signal quality threshold; step 2 periodically sending the channel measurement GAP and a GAP measurement start signal quality threshold; step 3 making a request for activating the shared channel GAP by UE (User Equipment); step 4 activating the shared channel GAP, periodically sending activation information and carrying out pilot frequency GAP measurement; step 5 reporting measurement information and switching; and step 6 deactivating the shared channel GAP. According to the method, pilot frequency measurement and switching for the UE which has an RRC (Radio Resource Control) connection in the group call and is in a concurrent state and the UE without the RRC connection can be realized, so that when the UE carries out GAP measurement, the UE cannot miss reception of business data of the shared channel, and thus the usage efficiency and the stability are improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for inter-frequency handover of trunking group calls in an LTE broadband trunking system. Background technique [0002] The trunking system is an efficient wireless communication system that supports a large number of wireless users for group communication with a small number of wireless channels by sharing wireless channels. [0003] With the rapid development of wireless LTE broadband technology, a broadband trunking system based on LTE broadband technology has emerged as the times require. Broadband LTE technology provides a larger channel capacity for the trunking system, thereby providing strong support for the trunking system to realize broadband trunking service scheduling. . [0004] In the actual commercial scenario of the LTE broadband trunking system, due to frequency planning or network planning, there will be situations where two adjacent areas...
