Method, system and communication unit for requesting a communication resource
First Claim
1. A method of requesting a communication resource by a wireless communication unit operating in a wireless UMTS communication system, wherein the wireless communication system provides for uplink channels for said wireless communication unit to communicate with a wireless serving communication unit and downlink channels for said wireless serving communication unit to communicate with said wireless communication unit, the method comprising the steps of:
- allocating a dedicated communication channel to said wireless communication unit by said wireless serving communication unit;
transmitting a communication resource request message on said dedicated uplink channel by said wireless communication unit to said wireless serving communication unit, wherein the communication resource request message is a PUSCH CAPACITY REQUEST message; and
transmitting an access allocation message to said wireless communication unit from said wireless serving communication unit on said dedicated downlink channel.

Abstract
A method of requesting a communication resource by a wireless communication unit operating in a wireless communication system. The wireless communication system provides for uplink and downlink channels. The method includes the steps of: allocating a dedicated communication channel to said wireless communication unit by a wireless communication serving unit; transmitting a communication resource request message (130) on said dedicated uplink channel by said wireless communication unit (110) to said wireless communication serving unit (120); and transmitting an access allocation message (140) to said wireless communication unit (110) from said wireless communication serving unit (120) on said dedicated downlink channel. A communication system and communication unit are also provided.
This provides the advantage that a dedicated channel is used for requesting shared resources thereby avoiding various problems, including clashes, associated with using a random access channel.

21. A method of requesting a communication resource by a wireless communication unit operating in a packet switched wireless communication system, wherein the wireless communication system provides for uplink dedicated and shared channels for said wireless communication unit to communicate with a wireless serving communication unit and provides for downlink dedicated and shared channels for said wireless serving communication unit to communicate with said wireless communication unit, the method comprising:
-
allocating a dedicated uplink channel to said wireless communication unit by said wireless serving communication unit; determining that said uplink dedicated channel can be used to send uplink allocation request messages; transmitting a communication resource request message on said dedicated uplink channel by said wireless communication unit to said wireless serving communication unit, wherein the communication resource request message is a uplink allocation request message; observing whether allocation messages are sent on a downlink dedicated channel or a downlink shared channel; and transmitting an allocation message to said wireless communication unit from said wireless serving communication unit on said dedicated downlink channel. - View Dependent Claims (22, 23, 24)

25. A method of requesting a communication resource by a wireless communication unit operating in a packet switched wireless communication system, wherein the wireless communication system provides for dedicated and shared uplink channels for said wireless communication unit to communicate with a wireless serving communication unit and provides for downlink dedicated and shared channels for said wireless serving communication unit to communicate with said wireless communication unit, the method comprising:
-
allocating a dedicated uplink channel to said wireless communication unit by said wireless serving communication unit; determining that said dedicated uplink channel can be used to request a shared uplink channel; transmitting a uplink allocation request message for a shared uplink channel on said dedicated uplink channel by said wireless communication unit to said wireless serving communication unit; and transmitting an allocation message for a shared uplink channel to said wireless communication unit from said wireless serving communication unit on said downlink dedicated channel.
