Abstract

In a communication system providing services with different quality of service requirements to a plurality of user equipment sharing resources of the communication system, resources of the communication system are allocated for service requests. The allocating of resources includes dividing the resources into at least two groups of resources, the different groups of resources being dedicated to different types of service.

Claims

1-14. -14. (canceled)

15. A method for providing random access to a communication system, the communication system providing services with different quality of service requirements to a plurality of user equipment sharing resources of the communication system, the method comprising:

allocating resources of the communication system for service requests, by at least dividing the resources into at least two groups of resources, the at least two groups of resources being dedicated to different types of service.

16. A method according to claim 15, wherein the at least two groups are dedicated to services with different quality of service.

17. A method according to claim 15, wherein the at least two groups are dedicated to services with different access classes.

18. A method according to claim 15, wherein the at least two groups are dedicated to services with different access service classes.

19. A method according to claim 18, wherein the communication system is a radio communications system.

20. A method according to claim 19, wherein said allocating of the at least two groups of resources for the user equipment is executed by at least one access point of a plurality of access points of the communication system.

21. A method according to claim 20, further comprising transmitting results of said allocating by the at least one access point over a first, predetermined channel to the plurality of user equipment.

22. A method according to claim 21, further comprising, upon receiving the results of said allocating, selecting, by an item of the user equipment, an appropriate resource from at least one of the at least two groups of resources, depending on a quality of service requirement of a service requested by the item of the user equipment.

23. A method according to claim 22, wherein the at least one quality of service requirement is a length of access time required for an access procedure.

24. A method according to claim 23, wherein the at least two groups of resources are access resources used by the user equipment during the access procedure.

25. A method according to claim 24, wherein the access resources are at least one of a frequency resource, a time resource and a code.

26. An access point in a communication system, comprising:

at least one processor programmed to allocate resources of the communication system for service requests, by at least dividing the resources into at least two groups of resources, the at least two groups of resources being dedicated to different types of service.

27. User equipment in a communication system, comprising:

at least one processor programmed to allocate resources of the communication system for service requests, by at least dividing the resources into at least two groups of resources, the at least two groups of resources being dedicated to different types of service.

28. A radio communications system, comprising:

at least one access point providing at least two groups of access resources during an access procedure; and

at least one item of user equipment having at least one processor programmed to allocate the access resources of the communication system for service requests, by at least dividing the access resources into at least two groups of the access resources dedicated to different types of service.
