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.
