The method for sending the trunking paging includes: after receiving a group paging request, a base station sending a paging message to trunking terminals in a present cell in a predetermined paging time slot, wherein the paging message includes a group identification of a group needing to be paged. A base station for sending the trunking paging includes a receiving module and a sending module. A method for receiving the trunking paging includes: after monitoring a paging message, when determining that a group identity included in the paging message is the same as a group identity of the group to which the present terminal belongs, a trunking terminal accessing the group service, and sending a paging response to base station, or not sending a paging response to base station. A trunking terminal for receiving the trunking paging includes a monitoring module, a judging module and a group service processing module.

Method and corresponding apparatus for sending and receiving trunking paging in LTE system

a method and system for managing a modulation and coding scheme (MCS). The method includes: a base station obtaining a downlink channel quality indicator (CQI) when a block error ratio of a trunking terminal reaches a pre-stored block error ratio threshold; the base station comparing a current CQI of a group with a CQI locally stored and reported by the group, wherein the CQI reported by the group is the minimum value in received CQIs reported by trunking terminals in the group respectively; and if a comparison result is that the CQI reported by the group is smaller than the current CQI of the group, the base station initiating an operation of updating an MCS value.

A method for implementing a trunking service, an evolved node B and a terminal are applied to a long term evolution system, and the method comprises: an evolved node B receiving a call request message sent by a calling terminal in a trunking common control channel (TCCCH) in an uplink direction, wherein, the TCCCH is used for bearing an uplink message of a trunking terminal. The above-mentioned technical solution implements a trunking function in a manner of newly adding a trunking service dedicated logic channel in an uplink/downlink direction and on the basis of an LTE system standard protocol, and supports concurrence of an LTE service and a trunking service in a same system. The demands of the trunking communications may be implemented on the basis of the LTE system, and the coexistence of the trunking service and the LTE service in a same system is implemented.

Method for implementing trunking service, evolved node B and terminal

A reverse power control method based on multi-carrier includes: an access network determining a forward carrier for a service, establishing a corresponding relationship between a reverse carrier corresponding to the forward carrier and the forward carrier, and transmitting the forward carrier and the corresponding relationship to the terminal (S); the access network determining a power control command of the service according to a service type of the service (S); the access network transmitting the power control command of the service to the terminal by the forward carrier (S). The present invention can reduce the power consumption of the terminal efficiently and improve the QoS.
