Abstract
A communications system and method are provided that enables the balancing and rate matching of different types of services used simultaneously by a mobile terminal. More specifically, the communications system includes a network and mobile terminal either of which is capable of matching the bit rates of a plurality of transport channels each handling a service to a bit rate of a physical channel handling multiplexed services using relative offset measures and predefined rules. The network assigns and signals the relative offset measures to the mobile terminal.

A method for controlling rate matching among different channels used to deliver services via a mobile terminal, said method comprising the steps of:
- signaling from a network to the mobile terminal, a plurality of relative offset measures associated with the different channels;
- and
- bit rate matching, within a selected one of the mobile terminal and the network, the different channels to a physical channel using predefined rules and the plurality of relative offset measures, wherein each channel supports at least one of the services that are multiplexed onto the physical channel which supports all of the services currently in use by the mobile terminal.
A method for balancing a plurality of bit rates of a plurality of transport channels to a bit rate of a composite transport channel, said method comprising the steps of:
- selecting one of the plurality of transport channels to be a reference transport channel;
- assigning a reference rate matching offset value to the reference transport channel;
- assigning respective rate matching offset values to each of the remaining plurality of transport channels;
- and
- rate matching the plurality of transport channels to the composite transport channel using predefined rules, the rate matching offset values and the reference rate matching offset value.
A communications system for matching a plurality of bit rates of a plurality of transport channels to a bit rate of a physical channel, said communications system comprising:
- a network for assigning and signaling a plurality of rate matching offset values respectively corresponding to the plurality of transport channels;
- a mobile terminal for receiving the plurality of rate matching offset values;
- one of said network and said mobile terminal operable to rate match the plurality of transport channels to the physical channel using predefined rules and relative quality measures associated with the respective rate matching offset values.
