Method and apparatus to control HSDPA activation/de-activation
View Patent ↗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.
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.
