Abstract: The present disclosure discloses a method and an apparatus for transmitting an overload message. By detecting, after determining a latest transmit slot for an overhead message to be transmitted, whether there is an idle paging slot between a current slot and the latest transmit slot, the method transmits the overhead message to be transmitted in the idle paging slot or in the latest transmit slot, such that, when scheduling overhead messages, a paging scheduling module of the base station system not only can meet the requirement of transmitting each overhead message at least once in one overhead message period as required in CDMA2000 protocol, but also automatically schedule the next overhead message when there is an idle slot in the paging channel, thus making the best use of the idle slots of the paging channel and shortening the actual transmission period for overhead messages, without affecting the transmission of other messages in the paging channel.

Abstract: The present invention discloses a method for Late-Entry in CDMA or other trunking systems. The method includes the following steps: after a group call is established, the base station checks the load condition of the paging channel, and if the load on the paging channel is relatively light, then the base station sends paging message carrying channel resource, and the terminal directly establishes the corresponding channel and the call is accessed through the matching for group identifier address after it receives the paging message; otherwise, the base station sends the paging message not carrying channel resource, and sends the message carrying channel resource after it receives the response message from the terminal, and then the terminal establishes the corresponding channel based on the resource information in said message and the call is accessed. By employing the method of the present invention, the load on the paging channel is alleviated and the access speed of the terminal is guaranteed.

Abstract: The method of present invention is used for addressing a broadcast message in a trunking system, in which said trunking communication system includes a base station and mobile stations. This method includes the following steps: adding a new index of trunking broadcast time slots, with all the mobile stations that support boundless capacity group call service monitoring these trunking broadcast time slots; the base station transmitting the paging message of the boundless capacity group call in the trunking broadcast time slot; and using the group identification as the broadcast address, allowing addressing to the group identification and not a single mobile station. The method of present invention efficiently solves the problem of paging channel capacity limitations of the boundless capacity group call service supported by CDMA trunking telecommunication systems, and greatly shortens the time of group call connection.

Abstract: The method of present invention is used for addressing broadcast message in trunk system, in which said trunk system includes base station, mobile station. Said method includes the following steps: adding a index of trunk broadcast time slot newly, all the mobile station that support boundless capacity group call service monitor these trunk broadcast time slots; the paging message of the boundless capacity group call transmitted by said base station is sent in the trunk broadcast time slot, which uses the group identification as the broadcast address, and address according to the group identification, not address to a single mobile station. The method of present invention efficiently solves the problem for the paging channel capacity limitation of boundless capacity group call service supported by CDMA trunk telecommunication system, and greatly shorten the time of group call connection.
