Abstract

A method and a user equipment (“UE”), for High Speed Downlink Packet Access (“HSDPA”) de-activation, the method determining whether a number of serving HSDPA cell changes of the UE exceeds a threshold within a predetermined time period; and; sending a transition indication from the UE to a network node to deactivate HSDPA if the threshold is exceeded for within the predetermined time period. Also, a method and a network node, for High Speed Downlink Packet Access de-activation, the method determining whether a number of serving HSDPA cell changes of a user equipment communicating with the network node exceeds a threshold within a predetermined time period; and; deactivating HSDPA for the UE if the threshold is exceeded within the predetermined time period.

Claims

1. A method, at a user equipment (“

UE”

), for High Speed Downlink Packet Access (“

HSDPA”

) de-activation, comprising;

determining whether a number of serving HSDPA cell changes of the UE exceeds a threshold within a time period;

sending a first transition indication from the UE to a network node to deactivate HSDPA if the threshold is exceeded within the time period; and

after a second time period, sending a second transition indication to the network node to resume HSDPA, wherein the second time period is one of a constant, a parameter signaled by the network, a function of network characteristics, and a function of HSDPA cell change frequency;

wherein the first transition indication indicates that the UE does not support HSDPA and the second transition indication indicates that the UE supports HSDPA.

2. The method of claim 1, wherein the determining step monitors the number of MAC-HS RESET indications received at the UE.

3. The method of claim 2, wherein the threshold is exceeded if the number of MAC-HS RESET indications within the time period is greater than a threshold.

4. The method of claim 1, wherein the first transition indication and the second transition indication are UE CAPABILITY INFORMATION messages.

5. A user equipment (UE) adapted for High Speed Downlink Packet Access (HSDPA) activation and de-activation comprising:

a communication subsystem;

a processor;

wherein the communication subsystem and the processor cooperate to;

determine whether a number of serving HSDPA cell changes of the UE exceeds a threshold within a time period;

send a first transition indication from the UE to a network node to deactivate HSDPA if the threshold is exceeded within the time period; and

after a second time period, send a second transition indication to activate HSDPA for the UE, wherein the second time period is one of a constant, a parameter signaled by the network, a function of network characteristics, and a function of HSDPA cell change frequency;

wherein the first transition indication indicates that the UE does not support HSDPA and the second transition indication indicates that the UE supports HSDPA.

6. The user equipment of claim 5, wherein the determining step monitors the number of MAC-HS RESET indications received at the UE.

7. The user equipment of claim 6, wherein the threshold is exceeded if the number of MAC-HS-RESET indications within the time period is greater than a value.

8. The user equipment of claim 5, wherein the first transition indication and the second transition indication are UE CAPABILITY INFORMATION MESSAGES.

9. A non-transitory computer readable medium having instructions stored thereon for execution by a processor of a user equipment (UE), the instructions comprising code for:

determining whether a number of serving HSDPA cell changes of the UE exceeds a threshold within a time period;

sending a first transition indication from the UE to a network node to deactivate HSDPA if the threshold is exceeded within the time period; and

after a second time period, sending a second transition indication to the network node to resume HSDPA, wherein the second time period is one of a constant, a parameter signaled by the network, a function of network characteristics, and a function of HSDPA cell change frequency;

wherein the first transition indication indicates that the UE does not support HSDPA and the second transition indication indicates that the UE supports HSDPA.

10. The non-transitory computer-readable medium of claim 9, wherein the determining step monitors the number of MAC-HS RESET indications received at the UE.

11. The non-transitory computer-readable medium of claim 10, wherein the threshold is exceeded if the number of MAC-HS RESET indications within the time period is greater than a threshold.

12. The non-transitory computer-readable medium of claim 9, wherein the first transition indication and the second transition indication are UE CAPABILITY INFORMATION messages.
