Abstract

A method of dealing with business conflict of a dual-card-dual-standby mobile phone includes the steps as follows. Calculate the period of the periodic location update of the main card and subordinate card respectively, and reset a new period of the periodic location update. Comparing to the original period of the periodic location update, the new period of the periodic location update is reduced by twice of a time for the mobile phone to do the location update. Thus, when the first location update is delayed due to the terminating call, it still has time for the second location update. Set priority level for each conflicting services, so as to avoid the service conflict, such as the conflict between the originating and terminating call and the location update, and the conflict between the location update of main card and subordinate card.

Claims

1. A method of dealing with service conflicts of a single-chipset dual-card-dual-standby mobile phone, wherein the single-chipset dual-card-dual-standby mobile phone simultaneously supports two cards to receive and transmit signals, and comprises an antenna, a radio frequency (RF) module, and a baseband processing chip, wherein the method comprising the steps of:

(A) setting a priority level for services;

(B) according to parameters broadcasted by a system message, calculating an original period of a periodic location update of a main card and an original period of a periodic location update of a subordinate card;

(C) setting a new period of the periodic location update of the main card and a new period of the periodic location update of the subordinate card, wherein the new period of the periodic location update of the main card is less than the original period of the periodic location update of the main card, and the original period of the periodic location update of the main card minus the new period of the periodic location update of the main card is no less than twice of a time for a mobile phone to do a location update, wherein the new period of the periodic location update of the subordinate card is less than the original period of the periodic location update of the subordinate card, and the original period of the periodic location update of the subordinate card minus the new period of the periodic location update of the subordinate card is no less than twice of a time for the mobile phone to do the location update; and

(D) after the step (C), processing the services according to the priority level of the services if there are any service conflicts, or processing the services according to a principle of first come first serve implementation if there are not any service conflicts.

2. The method, as recited in claim 1, wherein the priority level from high to low is listed as follows in turn:

a terminating call, a routing area update after cell reselection, a periodic routing area update, and an originating call.

3. The method, as recited in claim 1, wherein when the terminating call conflicts with the location update after cell reselection, process the terminating call firstly, buffer the location update and process the location update until the terminating call ends.

4. The method, as recited in claim 1, wherein when the terminating call conflicts with the periodic location update, process the terminating call firstly, because a period adjustment of the periodic location update can assure the update processed in time.

5. The method, as recited in claim 1, wherein when the location update after cell reselection conflicts with the periodic location update, process the location update after cell reselection firstly and then the periodic location update.

6. The method, as recited in claim 1, wherein when the location update after cell reselection conflicts with the originating call, process the location updated firstly, buffer a request of the originating call, and originate a random access request until the location update ends.

7. The method, as recited in claim 1, wherein when the periodic location update conflicts with the originating call, process the location update firstly, buffer a request of the originating call, and originate a random access request until the location update ends.
