Abstract

The present invention provides a method for dealing with the carrier conflict between the main card and subordinate card of a single-chip dual-card-dual-standby mobile phone, which includes a set one set of antenna, RF module and baseband processing chip and further comprises a radio resource adapter layer provided between the RRC layer and the physical layer. The RRC module calculates the position of the carriers of the main card and the subordinate card. The radio resource adapter layer determines the relative position between the carriers of main card and subordinate card so as to determine the type of the conflict, set priority levels to the services of the main card and subordinate card, and process the services according to the priority levels so as to avoid the conflict.

Claims

1. A method for dealing with a carrier conflict between a main card and a subordinate card of a single-chip dual-card-dual-standby mobile phone, which comprises a set one set of antenna, RF module and baseband processing chip, comprising steps of:

(a) calculating a position of a system information and paging message of said main card and said subordinate card,

(b) determining a type of a conflict between said main card and said subordinate card,

(c) setting priority levels for services according to said type of said conflict, and

(d) dealing with said service of higher priority level firstly, and abandon said service of lower priority level.

2. The method as recited in claim 1, wherein said position of said system information and paging message of said main card and said subordinate card are calculated in a radio resource adapter layer.

3. The method as recited in claim 2, wherein said radio resource adapter layer is provided between a physical layer and a radio resource control layer.

4. The method as recited in claim 1, wherein when a system information of said main card conflicts with a paging message of said subordinate card, comprising steps of:

when a single system information reception of said main card conflicts with said paging message of said subordinate card, arrange to receive said paging message of said subordinate card firstly and abandon said system information;

when a continuous system information reception for cell reselection of said main card conflicts with a paging message of said subordinate card, continue to receive said system information of said main card firstly and abandon said paging message of said subordinate card.

5. The method as recited in claim 1, wherein when a system information of said main card conflicts with a call service of said subordinate card, comprising steps of:

when said system information of said main card is earlier than said subordinate card, and it is a originating call service of said subordinate card, arrange to continuously receive said system information of said main card for one or two times firstly and delay an access request of said subordinate card;

when it is not a originating call service of said subordinate card, arrange to continuously receive said system information of said main card for one time firstly and delay an access request of the subordinate card;

when said system information of said main card is later than a service of said subordinate card, directly abandon a single system information reception, and delay a continuous system information reception of said main card for cell reselection until said services of said subordinate card ends.

6. The method as recited in claim 1, wherein when a system information of said main card conflicts with a system information of said subordinate card, comprising steps of:

when it is a single system information reception of both said main card and said subordinate card, abandon said system information of said subordinate card;

when there is only one continuous system information reception of said main card and said subordinate card, assure said continuous system information reception firstly;

when both said main card and said subordinate card continuously receive the system information, arrange said reception of said main card firstly and delay said reception of said subordinate card until the reception of said main card ends.
