Abstract
A method and apparatus for negotiating service configuration in a digital communication system is disclosed. In an exemplary embodiment the service negotiation system is implemented in a wireless spread spectrum communication system. The service configuration comprises data rates, frame formats and types of services. Types of service may include speech encoding, facsimile or digital data services. Further described herein is a digital transmitter and receiver using the service negotiation system to provide service configuration mutually acceptable at both ends of a communication link.
Claims29
In a wireless communication system in which a first communication device originates a communication service with a second communication device, a method for negotiating service configuration, comprising the steps of:
- generating a request message indicative of a requested service configuration of said first communication device;
- transmitting said request message;
- receiving said request message at said second communication device;
- determining if said requested service configuration is acceptable to said second communication device in accordance with current capabilities of said second communication device;
- generating a response message in accordance with said determination;
- transmitting said response message from said second communication device and receiving said response message at said first communication device;
- and
- determining, at said first communication device, whether to establish communication with said second communication device based on said response message, wherein said messages are transmitted over a common channel provided for general messaging services between communication devices of said wireless communication system, and wherein if said response message rejects said requested service configuration said method further comprises the step of communicating service negotiation messages over a traffic channel, said traffic channel being a communication channel allocated for communication between said first and second communication devices.
In a wireless communication system in which a first communication device originates a communication service with a second communication device, a system for negotiating service configuration, comprising
- service request generator means for generating a request message indicative of a service configuration of a predetermined set of first communication device service configurations at said first communication device;
- transmitter means for transmitting said request message;
- receiver means for receiving said transmitted message at said second communication device;
- service control means for determining if said service configuration request is acceptable to said second communication device in accordance with current capabilities of said second communication device;
- service response generator for generating a response message in accordance with said determination;
- and
- second transmitter means for transmitting said response message wherein said request message and said response message are transmitted over a common channel and wherein said common channel is provided for general messaging services between communication devices of said wireless communication system, and also wherein if said response message rejects said requested service configuration said system communicating service negotiation messages over a traffic channel, said traffic channel being a communications channel allocated for conducting communications between said first communications device and said second communications device.
