Method for allocating resources in the uplink of a wireless communication network and corresponding radio terminal

2/ Method according to claim 1, wherein said indication further takes into account real-time radio blocks that are being generated at said first module.

3/ Method according to claim 1, wherein said frames are generated and transmitted according to a layer-two radio link protocol, the header of said frames comprising a field containing said indication.

4/ Method according to claim 1, wherein said layer-two protocol is the Radio Link Control (RLC) protocol as specified in ETSI GSM04.60, said indication being located in the Countdown Value field of the RLC frame header.

5/ Method according to claim 2, wherein said real-time radio block contain packetized voice.

6/ Radio terminal to be used in a wireless communication network supporting real-time packet data services, said radio terminal comprising a data block source associated to a data block queue for generating and storing real-time data blocks and a frame generator associated to a frame queue for generating and storing frames encapsulating real-time data blocks or portions of real-time data block, said frames being transmitted in the uplink of said wireless communication network upon authorization from a resource allocation module, said radio terminal further comprising:

• a counting module for generating an indication on the number of stored real-time data blocks at said first module;
• an interface between said counting module and said second module for forwarding said indication to said second module;
• a frame generator for including said indication in each frame transmitted by said radio terminal.

7/ Resource allocation module to be used a wireless communication network supporting real-time packet data services for allocating resources in the uplink to radio terminals, said resource allocation module sending authorization to transmit frames, said frames comprising real time data blocks or portions of real time data blocks, said resource allocation module comprising:

• a storage medium for storing an indication on the number of stored real-time data blocks at each of said radio terminals;
• processing unit for determining the amount of resources to be allocated to each of said radio terminals depending on said indication.
