Abstract

The present invention provides a method of dealing with business conflict of a dual-card-dual-standby mobile phone. 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 business conflict of a dual-card-dual-standby mobile phone comprising a set of antenna, RF module, baseband processing chip, comprising steps of:

(a) setting a priority level for services;

(b) calculating a original period of a periodic location update of a maid card and a subordinate card;

(c) setting a new period of said periodic location update;

(d) processing said services according to said priority level of said services.

2. The method as recited in claim 1, wherein said new period of said periodic location update is reduced by no less than twice of a time for a mobile phone to do said location update, comparing to said original location update.

3. The method as recited in claim 1, wherein said 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.

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

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

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

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

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