Abstract (en)

[origin: WO0137494A2] A technique for spreading access attempts in a communication system entails transmitting messages from an application host to respective terminals via a packet data system, each of the messages including an access description element which specifies a time interval. Each terminal receives its respective message and generates a reply thereto. This reply is performed by making an initial uplink access on the random access channel. Once the first access is made, the network reserves radio resources for the terminal for use in conducting communication between the application host and the terminal. The initial access is transmitted following a lapse of the time interval specified in the message. The application host specifies different time intervals for different terminals. Accordingly, the access attempts made by the terminals are spread out over time to reduce congestion in the random access channel.
