Method for providing service and rate negotiation in a mobile communication system
First Claim
1. A method of negotiating a service configuration in a communication system in which a first communication device originates a communication service with a second communication device, wherein the first communication device shares at least one dedicated channel with the second communication device, the method comprising the steps of:
- transmitting, from said first communication device, an information data signal over a first dedicated channel;
receiving, at said second communication device, said transmitted information data signal;
generating, in said first communication device, a request message indicative of a proposed service configuration;
multiplexing, in said first communication device, said request message with said information data signal to produce a multiplexed signal allowing both the request message and the information data to be concurrently transmitted;
transmitting said multiplexed signal over said first dedicated channel;
receiving said multiplexed signal at said second communication device;
determining, in said second communication device, whether said proposed service configuration is acceptable to said second communication device;
generating, in said second communication device, a response message in accordance with said determination; and
transmitting said response message over a second dedicated channel.

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.

10. A communication device in a communication system capable of carrying voice traffic and data traffic over a plurality of dedicated and common channels, the communication device comprising:
-
a service negotiator for generating a request message indicative of a proposed service configuration;
a multiplexer, coupled to said service negotiator, for multiplexing said request message with an information data signal to produce a multiplexed signal allowing both the request message and the information data signal to be transmitted concurrently; and
a transmitter, coupled to said multiplexer, for transmitting said multiplexed signal over at least one dedicated channel. - View Dependent Claims (11, 12)
an encoder, interposed between said multiplexer and said transmitter, for encoding an information data signal in accordance with a service configuration selected by said service negotiator; and
a decoder, interposed between said multiplexer and said receiver, for decoding a received signal in accordance with said service configuration selected by said service negotiator.
