Abstract

An initial channel access message such as a Random Access Channel (RACH) preamble is used to mean that not only that a channel access has been requested by a mobile station (500) but also that a particular type of service has been requested. By associating a type of service (e.g., Dispatch, web browsing, etc.) with the particular signature that is used to form the RACH preamble it speeds up the service negotiation process. Both the communication system (600) and the MS (500) know what service is associated with which signature, so as soon as a RACH preamble is received by the system, it can determine if it has the resources available to accommodate the request.

Claims

1. A method for accelerating a service request negotiation between a communication device and a communication system the communication device is operating in, comprising the steps of:

(a) selecting a signature from a plurality of signatures stored in the communication device, each of the plurality of signatures is associated with a specific service/application; and

(b) transmitting an access request from the communication device to the communication system that includes the selected signature.

2. A method as defined in claim 1, wherein the plurality of signatures stored in the communication device are transmitted to the communication device by the communication system.

3. A method as defined in claim 1, wherein the communication system comprises a Wideband Code Division Multiple Access (WCDMA) system and the access request comprises a RACH preamable.

4. A method as defined in claim 1, wherein in step (a) the communication device selects the signature associated with a service/application the communication device is requesting access from the communication system for.

5. A method as defined in claim 2, wherein the plurality of signatures stored in the communication device are transmitted to the communication device by the communication system when the communication device registers with the system.

6. A method as defined in claim 1, further comprising the step of:

(c) transmitting an acquisition indicator from the communication system to the communication device, if after receiving the access request, the communication system determines it has the resources available to support the service/application associated with the signature received in the access request.

7. A method as defined in claim 1, further comprising the step of:

(c) transmitting a negative acknowledgment from the communication system to the communication device, if after receiving the access request, the communication system determines it does not have the resources available to support the service/application associated with the signature received in the access request.

8. A method as defined in claim 7, further comprising the step of:

(d) ceasing the service request negotiation in response to receiving the negative acknowledgment at the communication device.

9. A communication device operable within a communication system, comprising:

a controller;

a memory coupled to the controller; and

stored in the memory are a plurality of signatures used during access request transmissions with the communication system, and each signature is associated with a particular service/application type.

10. A communication device as defined in claim 9,

wherein the controller selects a signature from the plurality of signatures that is associated with a service/application the communication device needs access to from the communication system.

11. A communication device as defined in claim 10, further comprising:

a transmitter coupled to the controller; and

the controller causes the transmitter to transmit an access request that includes the signature selected by the controller.

12. A communication device as defined in claim 11, further comprising:

a receiver coupled to the controller; and

if the communication system transmits a negative acknowledgment in response to the access request sent by the communication device, the controller causes the communication device to cease its access request with the communication system.

13. A communication device as defined in claim 11, wherein the communication device comprises a communication device operable in a Wideband Code Division Multiple Access (WCDMA) system.

14. A communication device as defined in claim 13, wherein the access request comprises a Random Access Channel (RACH) preamble.

15. A Wideband Code Division Multiple Access (WCDMA) communication system having a communication device operating therein, comprising:

a system control; and

a memory coupled to the system control, the memory having stored therein a plurality of signatures for use by the communication device during access requests, each of the plurality of signatures is associated with a particular service/application type.

16. A WCDMA communication system as defined in claim 15, further comprising:

at least one base station coupled to the system control; and

the system control causes the plurality of signatures stored in the memory to be transmitted from the at least one base station to the communication device.

17. A WCDMA communication system as defined in claim 16, wherein the system control causes the plurality of signatures to be transmitted to the communication device when the communication device registers with the WCDMA communication system.

18. A WCDMA communication system as defined in claim 16, wherein the service/application type that the plurality of signatures are associated with are also transmitted to the communication device.

19. A WCDMA communication system as defined in claim 16, wherein the communication device transmits an access request using one of the plurality of signatures, and the communication system upon receiving the access request determines if it has the resources to support the service/application associated with the signature found in the access request.

20. A WCDMA communication system as defined in claim 19, wherein the WCDMA communication system sends a negative acknowledgment to the communication device if it determines it does not have the resources to support the service/application the communication device is requesting, the negative acknowledgment once received by the communication device causes the communication device to cease its access request.
