Problems solved by technology

Even if the base station sends the SPS activation command periodically and continuously for a period of time after the group is established, for the monitoring users who turn on the power later, if the UE does not join the group within the period when the SPS activation command is valid, the UE still listens. The activation command of the SPS cannot be obtained, so the monitoring of the group service cannot be realized

Abstract

The invention provides an activation method for semi-static scheduling and a trunking communication system based on semi-static scheduling. The method comprises the following steps that: a base station periodically sends a group paging message and sends an SPS (symbolic programming system) activation command based on a preset period; monitoring user terminals receive the group paging message and then join in a group; and the monitoring user terminals which already join in the group receives the SPS activation command, and then performs corresponding group service monitoring according to the physical resource determined by the SPS activation command. According to the invention, because the SPS activation command is not sent once, the monitoring user terminals which join in the group can determine the physical resource of the SPS, so as to activate group service, thus overcoming the difficulty that monitoring users which join in the group later cannot perform group monitoring.

Description

technical field [0001] The invention relates to a semi-static scheduling activation method and a semi-static scheduling-based trunking communication system, belonging to the technical field of long-term evolution (Long Term Evolution, referred to as: LTE) private network trunking communication. Background technique [0002] In the LTE system, a new scheduling method—Semi-Persistent Scheduling (Semi-Persistent Scheduling, SPS for short) technology is introduced for Voice over IP (VoIP) services. The semi-persistent scheduling method means that during the scheduling transmission process of LTE, the base station (referred to as: eNB) instructs the user equipment (User Equipment, referred to as: UE) through the physical downlink control channel (Physical Downlink Control Channel, referred to as: PDCCH) during initial scheduling If the UE recognizes that the scheduling information is semi-persistent scheduling, it saves the current scheduling information and sends or receives the...
