Abstract

Data is transmitted from a mobile or a base station to a booster or repeater station which, if it identifies that the same message has been retransmitted a preset number of times by the mobile or base station it automatically retransmits the data. The number of times a message has been retransmitted may be coded on each message or determined by comparing the retransmitted messages with a previously sent message that will have been stored in memory by the repeater and when the message in memory and retransmitted message are the same, registering another transmission of the message until the preset number is registered and then retransmitting the message preferrably from memory. In another arrangement the relay station receives and stores or otherwise identifies data from the mobile or base and listens for an acknowledgement from the receiving station, if no acknowledgement is received within a preset period of time the message is automatically retransmitted by the relay station. In either case the first time a message is received it will not except in certain circumstances be retransmitted by the repeater.
