Scheduling radio resources for symmetric service data connections
First Claim
1. A method for allocating radio channel resources in a radio communications system having a network with a network node, where the network node and a mobile radio station communicate over a radio interface, comprising:
- the network node determining whether a data communication requested between the network and the mobile radio station is associated with a symmetric service or an asymmetric service;
if the data communication is associated with a symmetric service, the network node establishing a symmetric data connection between the mobile radio station and the network for communicating data packets associated with the data communication; and
the network node assigning substantially the same amount of radio channel resources to the symmetric connection for transporting data packets uplink from the mobile radio station to the network as for transporting data packets downlink from the network to the mobile radio station,wherein the symmetric data communication is a voice over IP (VoIP) communication and the radio communications system is a GPRS or EDGE type system, the radio channel resources are time slots, and the symmetric VoIP connection includes an uplink temporary block flow (TBF) and a downlink TBF,wherein for multiple mobile radio stations in a cell each associated with a VoIP data communication, the method further comprising;
pairing VoIP data communications when assigning time slots,assigning a first VoIP data communication in a pair to a first time slot in which to transmit and a second time slot in which to receive, andassigning a second VoIP data communication in the pair to the first time slot in which to receive and the second time slot in which to transmit.

Abstract
Radio channel resources are allocated in a radio communications system based on whether a requested data communication requested is associated with a symmetric service or an asymmetric service. If the data communication is associated with a symmetric service, a symmetric connection between the mobile radio station and the radio network is established for communicating data packets associated with the data communication. Radio channel resources are assigned to the symmetric connection for transporting the data packets between the mobile radio station and the radio network. The symmetric connection is assigned substantially the same amount of radio channel resources in an uplink direction as in a downlink direction. In one example, the symmetric data communication is a voice over IP (VoIP) communication. One example environment is a GPRS/EDGE type system where the radio channel resources are time slots and the symmetric connection includes an uplink temporary block flow (TBF) and a downlink TBF.
