Abstract

A method for transmitting mobile originated requests by a mobile station with a first subscriber identity card and a second subscriber identity card, executed by a processor, is provided. It is determined whether a preference setting has been enabled. A preferred subscriber identity card is obtained from the first subscriber identity card and the second subscriber identity card when the preference setting has been enabled. The mobile originated request is issued to a called party via the preferred subscriber identity card when the preference setting has been enabled.

Claims

1. A method for transmitting a mobile originated request by a mobile station with a first subscriber identity card and a second subscriber identity card, performed by a processor of the mobile station, comprising:

determining whether a preference setting has been enabled;

obtaining a preferred subscriber identity card from the first and second subscriber identity cards when the preference setting has been enabled; and

issuing the mobile originated request to a called party via the preferred subscriber identity card when the preference setting has been enabled.

2. The method as claimed in claim 1, wherein the preference setting is enabled via a man-machine interface (MMI).

3. The method as claimed in claim 1, further comprising:

issuing the mobile originated request to the called party via one subscriber identity card from the first subscriber identity card and the second subscriber identity card determined by a rule when the preference setting is disabled.

4. The method as claimed in claim 3, wherein a condition of the rule comprises roaming information regarding the roaming statuses of the first and second subscriber identity cards, and the mobile originated request is issued to the called party via one subscriber identity card without roaming.

5. The method as claimed in claim 3, wherein a condition of the rule comprises cell information regarding whether at least a certain percentage or number of the neighboring cell identities (IDs) corresponding to a first cell that the first subscriber identity card camps on is present in a plurality of preset low-fee cell IDs, and, if so, the mobile originated request is issued to the called party via the first subscriber identity card, otherwise, the mobile originated request is issued to the called party via the second subscriber identity card.

6. The method as claimed in claim 3, wherein a condition of the rule comprises fare plan information regarding the charges of the first and second subscriber identity cards at a current time, and the mobile originated request is issued to the called party via one specific subscriber identity card with the lowest charge.

7. A method for transmitting a mobile originated request by a mobile station with a first subscriber identity card and a second subscriber identity card, performed by a processor of the mobile station, comprising:

obtaining a first roaming information indicating whether the first subscriber identity card is in a roaming or non-roaming status, and a second roaming information indicating whether the second subscriber identity card is in a roaming or non-roaming status;

determining one subscriber identity card from the first subscriber identity card and the second subscriber identity card according to the first roaming information and the second roaming information; and

issuing the mobile originated request to a called party via a cell that the determined subscriber identity card camps on.

8. The method as claimed in claim 7, wherein the first subscriber identity card is determined when the first roaming information indicates that the first subscriber identity card is in a non-roaming status and the second roaming information indicates that the second subscriber identity card is in a roaming status.

9. The method as claimed in claim 7, further comprising:

determining a preferred subscriber identity card from the first subscriber identity card and the second subscriber identity card when the first roaming information and the second roaming information indicate that the roaming statuses of the first and second subscriber identity cards are the same.

10. The method as claimed in claim 9, wherein the first roaming information indicates that the first subscriber identity card is in a non-roaming status when a Mobile Country Code (MCC) and a Mobile Network Code (MNC) stored in the first subscriber identity card are the same as that of a System Information (SI) broadcasted in a first cell that the first subscriber identity card camps on, and the second roaming information indicates that the second subscriber identity card is in a non-roaming status when an MCC and an MNC stored in the second subscriber identity card are the same as that of an SI broadcasted in a second cell that the second subscriber identity card camps on.

11. A method for transmitting a mobile originated request by a mobile station with a first subscriber identity card and a second subscriber identity card, performed by a processor of the mobile station, comprising:

obtaining a first cell identity report from a first cell that the first subscriber identity card camps on, wherein the first cell identity report comprises a plurality of cell identities (IDs) of the neighboring cells of the first cell;

obtaining a plurality of low-fee cell IDs from a storage device of the mobile station;

determining one subscriber identity card from the first subscriber identity card and the second subscriber identity card according to the first cell identity report and the low-fee cell IDs; and

issuing the mobile originated request to a called party via a cell that the determined subscriber identity card camps on.

12. The method as claimed in claim 11, wherein the step of determining the subscriber identity card further comprises:

determining the first subscriber identity card when at least a certain percentage or number of the neighboring cell IDs is present in the low-fee cell IDs; and

determining the second subscriber identity card when a certain percentage or number of the neighboring cell IDs is not present in the low-fee cell IDs.

13. The method as claimed in claim 11, wherein the first cell identity report is obtained from System Information (SI) broadcasted in the first cell.

14. A method for transmitting a mobile originated request by a mobile station with a first subscriber identity card and a second subscriber identity card, performed by a processor of the mobile station, comprising:

obtaining a dialed number of a called party and a current time;

identifying a called operator according to the dialed number;

determining one subscriber identity card from the first subscriber identity card and the second subscriber identity card according to the current time and a fare plan for the identified called operator; and

issuing the mobile originated request to the called party via the determined subscriber identity card. {step S1216}

15. The method as claimed in claim 14, wherein the step of determining the subscriber identity card further comprises:

reading a first fare plan for the first subscriber identity card and a second fare plan for the second subscriber identity card from a storage device of the mobile station;

filtering out at least one first record related to the identified called operator and the current time from the first fare plan and at least one record related to the identified called operator and the current time from the second fare plan; and

determining one subscriber identity card with the lowest charge by comparing charge rates recorded in the filtered out first record and second record. {step S1214}

16. The method as claimed in claim 14, wherein the step of determining the subscriber identity card further comprises:

reading a first fare plan for the first subscriber identity card and a second fare plan for the second subscriber identity card from a storage device of the mobile station;

filtering out at least one first record related to a prefix number of the dialed number and the current time from the first fare plan and at least one second record related to the prefix number of the dialed number and the current time from the second fare plan; and

determining one subscriber identity card with the lowest charge by comparing charge rates recorded in the filtered out first record and second record.

17. The method as claimed in claim 14, wherein the first or second fare plan is obtained from a man-machine interface.

18. The method as claimed in claim 14, wherein the first or second fare plan is obtained from at least one advice of charge (AoC) message sent by a first network operator providing the first subscriber identity card or a second network operator providing the second subscriber identity card.

19. The method as claimed in claim 14, wherein the first or second fare plan is obtained by parsing a monthly bill provided by a first network operator providing the first subscriber identity card or a second network operator providing the second subscriber identity card.
