specific Embodiment 1

[0094] In the trunking private network, the trunking group makes voice calls.

[0095] 1) Activation of semi-persistent scheduling:

[0096] For online users:

[0097] (1) Currently, some trunk group users are idle, and some trunk terminals are performing data services; when a group call is established, these trunk group users join the group;

[0098] (2) When a group voice user needs voice services, the base station establishes an SPS bearer for the group user. During the establishment process, the base station will allocate TSPS-RNTI resources and SPS configuration. Assuming that the TSPS-RNTI value is 100, the configuration The information includes but is not limited to the logical channel information for cluster SPS services with a period of 20ms for SPS configuration;

[0099] (3) After the group SPS is established successfully, the base station immediately packs the configuration information of TSPS-RNTI and SPS into the cluster control channel, and the cluster control...

specific Embodiment 2

[0127] In the mixed networking of the cluster and the public LTE network, the base station sends periodic media information to the cluster users. For hybrid networking, cluster scheduling can be performed in various ways, for example:

[0128] (1) For cluster scheduling and LTE scheduling are separated in the time domain, according to a certain period, some subframes are scheduled for cluster users, and some subframes are scheduled for LTE users; for this case, the cluster scheduling in this embodiment Can only be done on cluster subframes.

[0129] (2) Separate the cluster scheduling and LTE scheduling in the frequency domain, and at a scheduling moment, the bandwidth is divided in proportion, a part is scheduled for cluster users, and the remaining bandwidth is scheduled for LTE users; for this case, the cluster in this embodiment Scheduling can only be scheduled on the frequency resources of the cluster.

Abstract

The invention discloses a trunking semi-persistence scheduling resource allocation method, a base station and a terminal. After the base station establishes SPS bearing for a trunking group, SPS configuration information and trunking semi-persistence scheduling identifier used for identifying semi-persistence bearing of the trunking group are sent to the trunking group through a trunking control channel, wherein the SPS configuration information includes a business data transmission period; after notifying the trunking group to activate the SPS bearing, the base station periodically transmits the trunking semi-persistence scheduling identifier, an semi-persistence scheduling resource instruction in DCI (downlink control information) generated when the SPS bearing is activated and the SPS configuration information in the trunking control channel, and the semi-persistence scheduling resource instruction includes business data transmission time frequency resources. The scheme can solve the problem of SPS scheduling in lagged access to trunking user equipment, thereby reducing use of PDCCH resources of a whole trunking system, and improving the resource utilization rate of the whole system.

Description

technical field [0001] The invention relates to the field of communication clusters, in particular to a cluster semi-static scheduling resource configuration method, a base station and a terminal. Background technique [0002] The trunking system plays an irreplaceable role in the professional communication field of the digital communication system because of its one-stop response. Existing digital trunking communication systems mainly include: TETRA (Terrestrial Trunked Radio) system, integrated digital enhanced network (iDEN, Integrated Digital Enhanced Networks) system, open trunking architecture (GoTa, Global Open Trunking Architecture) system and GT800 system etc. [0003] The existing Long Term Evolution (LTE, Long Term Evolution) technology is a system based on a single-user service, and has not clearly formulated a trunking service based on multi-user calls. Moreover, the voice service is one of the most important services in the trunking system, and the voice serv...
