Abstract

There is disclosed a system and method for sending intermittent messages on the A3 interface to provide, for use in a base station, a message transfer system for transmitting and receiving intermittent messages. The transfer system comprises i) a controller for inserting an intermittent message into a data frame; ii) a selection distribution unit in the base station for receiving and processing the intermittent messages; and iii) a transmitter for sending data frames with the intermittent message inserted to other base stations via the A3 interface.

Description

technical field [0001] The present invention is directed generally to cellular communications, and more particularly to systems for sending messages in a broadband cellular communications system. Background technique [0002] Communications in a cellular communication system typically take place between a sending device and a receiving device over communication resources called communication channels. Code Division Multiple Access (CDMA) is a cellular communication mode that allows simultaneous communication (voice and data) between multiple users on a single frequency. Simultaneous operation is achieved by using different codes for each user, and a single signal is only discernible after decoding. The signal received at a base station or mobile unit consists of many frequency and time overlapping coded signals from a single mobile unit or base station. Furthermore, in a CDMA wireless system, a mobile unit is linked to more than one base station during a communication. As...
