Selective retry of attach and location update procedures

1. In a GPRS network operating in network operation mode 1 , a method of reducing an amount of time necessary to complete at least one form of connectivity when a first attempt for a combined procedure is not accepted by the network, the method comprising:

setting a first timer after the first attempt;

performing a second attempt for the combined procedure; and

attempting to gain access only to GSM services of the network immediately and unconditionally after the second attempt for the combined procedure is not accepted by the network;

setting a second timer if access to GSM-only services of the network is gained; and

based upon the second timer, attempting the combined procedure to the network upon gaining access to the GSM-only services.

2. The method of claim 1 , further comprising attempting the combined procedure periodically based upon the second timer after gaining access to the GSM-services.

3. The method of claim 1 , wherein the combined procedure is a combined attach procedure.

4. The method of claim 1 , wherein the combined procedure is a combined location update procedure.

5. A method for reducing an amount of time necessary to complete at least one form of connectivity between a mobile device and a GPRS network operating in network operation mode 1 , comprising:

attempting a combined attach procedure to the network;

starting a first timer;

if the combined attach procedure is not accepted by a first expiry of the first timer,

repeating the attempt for the combined attach procedure to the network;

resetting and restarting the first timer; and

attempting to gain access only to GSM services of the network immediately after and as a direct result of a second expiry of the first timer if the combined attach procedure is not accepted by the second expiry of the first timer;

setting a second timer if access to GSM-only services of the network is gained; and

based upon the second timer, attempting the combined procedure to the network upon gaining access to the GSM-only services.

6. The method of claim 5 , wherein the second timer is used to periodically attempt the combined attach procedure upon gaining access to the GSM services.

7. The method of claim 5 , further comprising attempting the combined attach procedure after waiting for a period of time according to the second timer upon gaining access to the GSM services.

8. A method for reducing an amount of time necessary to complete at least one form of connectivity between a mobile device and in a GPRS network operating in network operation mode 1 , comprising:

attempting a combined location update procedure to the network;

starting a first timer;

if the combined location update procedure is not accepted by a first expiry of the first timer,

repeating the attempt for the combined location update procedure to the network;

resetting and restarting the first timer; and

attempting a GSM-only location update procedure to the network immediately after and as a direct result of a second expiry of the first timer if the combined location update procedure is not accepted by the second expiry of the timer;

setting a second timer if the GSM-only location update is accepted by the network, and

based upon the second timer, attempting the combined location update procedure upon acceptance of the GSM-only location update.

9. The method of claim 8 , wherein the second timer is used to periodically attempt the combined location update once the GSM-only location update is accepted by the network.

10. The method of claim 8 , further comprising attempting the combined location update after waiting for a period of time according to the second timer once the GSM-only location update is accepted by the network.

11. A method of reducing an amount of time to connect to a network when a first attempt for a combined procedure is not accepted by the network, the method comprising:

performing a first attempt of a combined procedure to the network;

performing a second attempt to the combined procedure to the network if the network does not accept the first attempt of the combined procedure based upon the expiration of a first timer;

attempting to gain access only to GSM services of the network immediately and unconditionally after the second attempt for the combined procedure is not accepted by the network;

setting a second timer if access to GSM-only services of the network is gained; and

based upon the second timer, attempting the combined attach procedure to the network upon gaining access to the GSM-only services.

12. The method of claim 11 , wherein the second timer is used to periodically attempt the combined procedure upon gaining access to the GSM services of the network.

13. The method of claim 11 , further comprising attempting the combined procedure after waiting for a period of time according to the second timer upon gaining access to the GSM services.

14. The method recited in claim 13 , wherein the second timer is set to approximately 15 seconds.

15. The method recited in claim 12 ,

wherein the periodically attempting the combined procedure is performed until GPRS services are obtained.

16. The method of claim 12 , wherein the combined procedure is a combined attach procedure.

17. The method of claim 12 , wherein the combined procedure is a combined location update procedure.

18. A method of reducing an amount of time to connect to a network when a first attempt for a combined procedure is not accepted by the network, the method comprising:

performing a first attempt of a combined procedure to the network;

performing a second attempt of the combined procedure to the network if the network does not accept the first attempt of the combined procedure before the expiration of a first timer;

attempting to gain access only to GSM services of the network immediately and unconditionally after the second attempt for the combined procedure is not accepted by the network, wherein the total time for performing the first and second attempts is less than 120 seconds;

setting a second timer if access to GSM-only services of the network is gained; and

based upon the second timer, attempting the combined procedure to the network upon gaining access to the GSM-only services.

19. The method of claim 18 , wherein the combined procedure is a combined attach procedure.

20. The method of claim 18 , wherein the combined procedure is a combined location update procedure.
