Data-capable network prioritization with reduced delays in data service
View Patent ↗In one illustrative method, a method in a mobile station for use in reducing delays for data communications is described. The mobile station causes a request for packet data service to be sent to a wireless communication network. If the request for the packet data service is denied in response to the request, then the mobile station is set in a deregistered state. In addition, the mobile station initializes a timer with an initial value that is less than a periodic location update timer value which is broadcasted by the wireless communication network, and runs the timer. In response to an expiration of the timer, the mobile station causes another request for the packet data service to be sent to the wireless communication network.
1. A method in a mobile communication device for use in reducing delays for packet data communications in a wireless communication network, the method comprising:
causing a request for a packet data service to be sent to the wireless communication network;
if the request for the packet data service is denied in response to the request, then:
setting the mobile communication device in a deregistered state;
initializing a timer with an initial value that is less than a periodic location update timer value which is broadcasted by the wireless communication network, and running the timer; and
causing another request for the packet data service to be sent to the wireless communication network in response to an expiration of the timer.
2. The method of claim 1 , further comprising:
receiving, from the wireless communication network, the periodic location update timer value and storing it in memory of the mobile communication device.
3. The method of claim 1 , further comprising:
operating the mobile communication device in the wireless communication network using the packet data service if the request for the packet data service is accepted in response to the request.
4. The method of claim 1 , further comprising:
testing the periodic location update timer value; and
initializing the timer with the initial value if the periodic location update timer value is greater than the initial value.
5. The method of claim 1 , further comprising:
testing the periodic location update timer value;
if the periodic location update timer value is greater than the initial value, initializing the timer with the initial value; and
otherwise, if the periodic location update timer value is less than the initial value, initializing the timer with the periodic location update timer value.
6. The method of claim 1 , wherein the timer comprises a timer 3302 .
7. The method of claim 1 , wherein the periodic location update timer value comprises a timer 3212 .
8. The method of claim 1 , wherein the request for the packet data service comprises a General Packet Radio Service (GPRS) attach request.
9. The method of claim 1 , wherein the request for the packet data service comprises a Routing Area Update (RAU) request.
10. The method of claim 1 , wherein the deregistered state comprises a General Packet Radio Service (GPRS) Deregistered state.
11. The method of claim 1 , which is embodied in a computer program product comprising a storage medium and computer instructions stored in the storage medium, wherein the computer instructions are executable by one or more processors of the mobile communication device for performing the method.
12. A mobile communication device, comprising:
one or more processors;
a wireless transceiver coupled to the one or more processors;
memory coupled to the one or more processors;
the one or more processors being configured to:
cause a request for a packet data service to be sent, via the wireless transceiver, to the wireless communication network;
if the request for the packet data service is denied in response to the request, then:
set the mobile communication device in a deregistered state;
initialize a timer with an initial value that is less than a periodic location update timer value which is broadcasted by the wireless communication network, and run the timer; and
cause another request for the packet data service to be sent, via the wireless transceiver, to the wireless communication network in response to an expiration of the timer.
13. The mobile communication device of claim 12 , wherein the one or more processors are further configured to receive, from the wireless communication network, the periodic location update timer value and store it in memory.
14. The mobile communication device of claim 12 , wherein the one or more processors are further configured to operate the mobile communication device in the wireless communication network using the packet data service if the request for the packet data service is accepted in response to the request.
15. The mobile communication device of claim 12 , wherein the one or more processors are further configured to test the periodic location update timer value and, if the periodic location update timer value is greater than the initial value, initialize the timer with the initial value.
16. The mobile communication device of claim 12 , wherein the timer comprises a timer 3302 .
17. The mobile communication device of claim 12 , wherein the periodic location update timer value comprises a timer 3212 .
18. The mobile communication device of claim 12 , wherein the request for the data service comprises a General Packet Radio Service (GPRS) attach request.
19. The mobile communication device of claim 12 , wherein the request for the data service comprises a Routing Area Update (RAU) request.
20. A communication system, comprising;
a wireless communication network;
a mobile communication device configured to communicate in the wireless communication network;
the mobile communication device being further configured to:
cause a request for a packet data service to be sent to the wireless communication network;
if the request for the packet data service is denied in response to the request, then:
set the mobile communication device in a deregistered state;
initialize a timer with an initial value that is less than a periodic location update timer value which is broadcasted by the wireless communication network, and run the timer; and
cause another request for the packet data service to be sent, via the wireless transceiver, to the wireless communication network in response to an expiration of the timer.
