  • Patent number: 10117221
    Abstract: 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.

  • Patent number: 8989793
    Abstract: A reverse power control method includes: a base station presetting reverse outer loop threshold values according to radio configuration (RC) types; in the accessing process of a terminal, the base station selecting the preset reverse outer loop threshold value according to the RC type fed back by the terminal; the base station receiving the Eb/Nt of the reverse channel and comparing the received Eb/Nt with the selected reverse outer loop threshold value, if the Eb/Nt is larger than the reverse outer loop threshold value, the base station instructing the terminal to decrease the transmitting power; if the Eb/Nt is smaller than the reverse outer loop threshold value, the base station instructing the terminal to increase the transmitting power, so as to guarantee that the terminal accesses successfully. An apparatus for implementing reverse close loop power control and an apparatus for implementing reverse outer loop power control are also provided.
