A Different-Frequency Measurement Method in Trunking System

Abstract

The invention discloses a different-frequency measurement method in a clustering system. The method comprises the steps that clustering user equipment UE extracts configuration information of clustering different-frequency measurement from received system messages and stores the configuration information when accessing a network; and the clustering UE carries out different-frequency measurement according to the stored configuration information of the clustering different-frequency measurement after the clustering UE joins a clustering broadcast group. Through application of the method, the measurement configuration for a user can be simplified, and the different-frequency measurement and clustering paging are ensured not to influence each other.

Description

technical field [0001] The present application relates to channel measurement technology in a communication system, in particular to a method for inter-frequency measurement in a trunking system. Background technique [0002] In LTE, when a UE moves in an environment covered by neighboring cells with different frequencies, it needs to measure signal quality (that is, measure different frequencies) so as to select a suitable cell for service. In LTE, when the UE performs the above-mentioned inter-frequency measurement, it cannot perform other normal services. This period of time is called a measurement interval. [0003] In the current system, when the user is doing normal business, it is assumed that the inter-frequency measurement is caused by the change of the signal quality. Afterwards, if the trunking communication group to which the user belongs has a trunking broadcast communication initiation, the network side needs to broadcast to the trunking The measurement interv...

Problems solved by technology

[0006] 1. When there are enough users belonging to the trunking broadcast group, the number of air interface configuration messages for all users is large, occupying air interface resources, and affecting the access delay of new users

At the same time, the application scenarios of the trunking broadcast group are relatively frequent, so the probability of this problem occurring in the inter-frequency networking scenario is extremely high

[0007] 2. At present, when the system is designed, when configuring user frequency measurement, it does not consider avoiding the timing of cluster paging, which causes users to lose cluster paging and cannot correctly join the active group, and the group service is abnormal.
