Subnetwork dependent convergence protocol for a mobile radio network
First Claim
1. A method of operating a mobile radio network in which data is assembled into units by a first convergence protocol layer prior to transmission of the data to a second, peer convergence protocol layer, said data being provided to the first convergence protocol layer by one of a plurality of convergence protocol layer users, the method comprising:
- assigning at least one access point identifier to each user; and
exchanging between said first and second layers one or more compression control message, each message containing a data compression/decompression algorithm identifier, a set of parameters for the identified algorithm, and identification of at least one access point identifier which is to make use of the identified algorithm.

Abstract
A method of operating a mobile radio network in which data is assembled into units by a first convergence protocol (SNDCP) layer prior to transmission of the data to a second; peer convergence protocol (SNDCP) layer. Data is provided to the first convergence protocol layer by one of a plurality of convergence protocol layer users (e.g. PDP entities). The method comprises assigning at least one access point identifier (NSAPI) to each user and exchanging between first and second layers one or more set-up messages (XID), each message containing a data compression/decompression algorithm identifier, a set of parameters for the identified algorithm, and a bitmap of access point identifiers, where the bitmap indicates those access point identifiers which are to make use of the identified algorithm and those which are not.

7. A mobile radio device for use in a mobile radio network in which data is assembled into units by a first convergence protocol layer prior to transmission of the data to a second, peer convergence protocol layer, the first convergence protocol layer being in the mobile radio device and the second convergence protocol layer being in the mobile radio network, said data being provided to the first convergence protocol layer by one of a plurality of convergence protocol layer users, each user having assigned to it at least one access point identifier, wherein the mobile radio device is adapted to exchange between its first convergence protocol layer and the second convergence protocol layer of the network one or more compression control message, each message containing a data compression/decompression algorithm identifier, a set of parameters for the identified algorithm, and identification of at least one access point identifier which is to make use of the identified algorithm.
