When the SIM card 1 is performing data traffic transmission and other operations, the time slot for the SIM card 2 to periodically receive the BCH, the PCH and the like collides with the time slot for the SIM card 1 to perform data traffic transmission.
In the prior art, when data received by the SIM card 1 and the SIM card 2 collide, data of one of the SIM cards needs to be discarded through arbitration.
However, the above arbitration method easily causes the data traffic transmission rate of the SIM card in the data transmission state to decrease.

Detailed Description
In the prior art, when the SIM card 1 performs data transmission service and other operations, the time slot of the BCH periodically received by the SIM card 2 conflicts with the time slot of the data transmission service performed by the SIM card 1, and the data of one SIM card needs to be discarded through arbitration. In general, it is determined that the priority of the BCH is higher than the priority of data traffic transmission, and therefore, when the traffic of the SIM card 1 collides with the traffic of the SIM card 2, the traffic data corresponding to the SIM card 1 is discarded, and the BCH of the SIM card 2 is received, which results in a decrease in the data traffic transmission rate of the SIM card in a data transmission state.
In the embodiment of the invention, when the time slot of the SIM card in the data transmission state for transmitting data conflicts with the time slots of other SIM cards for receiving the paging indication information, the priority of the data information transmitted by the current SIM card is adjusted. When the data information of the current SIM card is more important, the priority of the data information is increased, so that the mobile terminal receives the data information of the current SIM card and discards the paging indication information of other SIM cards, thereby avoiding that when service conflict occurs, the data information of the SIM card in a data transmission state is discarded because the priority is lower than the paging indication information of other SIM cards, and the data transmission rate is reduced.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention comprehensible, specific embodiments accompanied with figures are described in detail below.
An embodiment of the present invention provides a method for processing a service conflict of a multi-card multi-standby mobile terminal, which is described in detail below with reference to fig. 1 through specific steps.
Step S101, when the current SIM card is in a data transmission state, detecting whether the time position of other SIM card service operation conflicts with the time position of the current SIM card data transmission.
In a specific implementation, when the current SIM card is in a data transfer state, the other SIM cards are in an idle mode. At this time, the service operations executed by other SIM cards mainly include: the operations of timing reception of BCH/PCH, new cell search and reporting of synchronized cells.
And if the current SIM card performs data transmission and detects that other SIM cards perform service operation in the data transmission process of the current SIM card, determining that the time position of the current SIM card conflicts with the time positions of the other SIM cards. In the embodiment of the present invention, when the time and position of the current SIM card conflicts with those of other SIM cards, step S102 may be executed; and when the time positions of the current SIM card and other SIM cards are not conflicted, each SIM card executes the corresponding service operation.
For example, for an LTE dual-card dual-standby mobile terminal, one SIM card is an LTE card and is in a data transmission mode, and the other SIM card is an LTE/3G/2G card and is in an idle mode. At t0At the moment, the LTE card in the data transmission mode receives data sent by the network side through a Physical Downlink Shared Channel (PDSCH), and if another LTE card is in the data transmission mode, the other LTE card receives data sent by the network side through the PDSCHSIM card0And receiving the PCH all the time, and then judging that the two SIM cards have time conflict.
And step S102, when time conflict occurs, judging whether the priority of the data information is adjusted or not according to the data information transmitted by the current SIM card.
In a specific implementation, the priority of the data information can be adjusted according to the data information transmitted by the current SIM card. The data transmitted by the current SIM card may be uplink data or downlink data. Whether the priority of the transmitted data information is adjusted can be determined by judging whether the data information transmitted by the current SIM card meets a preset priority adjusting condition. When the priority adjustment condition is met, the priority of the data information transmitted by the current SIM card is improved; when the priority adjustment condition is not satisfied, the priority of the data information may be kept unchanged or the low priority of the data information may be lowered.
In the embodiment of the invention, when the priority of the data information is improved, the priority of the data information can be adjusted to be higher than the priority of the service operation of other SIM cards; the priority of the data information can also be adjusted to be higher than the priority of partial service operation in other SIM cards and lower than the priority of other partial service operation.
For example, after the priority of the data information is adjusted, the adjusted priority of the data information is higher than the priority of operations of receiving BCH/PCH, searching for a new cell, measuring and reporting a synchronized cell and the like of other SIM cards.
For another example, after the priority of the data information is increased, the adjusted priority of the data information is lower than the priority of the other SIM cards for receiving the BCH/PCH, but higher than the priority of the other SIM cards for searching for a new cell, measuring and reporting a synchronized cell, and the like.
In the embodiment of the present invention, whether to adjust the priority of the data information may be determined according to the subframe type corresponding to the data information.
In an embodiment of the present invention, a subframe type of data information of a current SIM card is acquired, and a number of subframes in a corresponding data frame, which is the same as the subframe type of the data information, is acquired. When the number of the subframes with the same type as the subframes of the data information is smaller than a preset value, the data information is judged to be important, and if the subframes are discarded, the data information can have a large influence on the data transmission of the current SIM card, so that the priority of the data information can be improved, and the data information is prevented from being discarded due to the lower priority.
For example, the structure of the data frame is DSUDDDDDDD, D is a downlink subframe, U is an uplink subframe, and S is a special subframe. The subframe corresponding to the data information of the current SIM card is an uplink subframe U, and the number of the uplink subframes included in the data frame is only 1 and is less than 2 preset. Therefore, the importance of the data information is determined to be high, and the priority of the data information is increased.
In the embodiment of the present invention, whether to adjust the priority of the data information may also be determined according to the number of times of the consecutive automatic retransmission failure of the data information.
In an embodiment of the present invention, when the number of times of the data information continuous automatic retransmission failure reaches a preset value, if the data information cannot be successfully transmitted, the mobile terminal may drop the link, so that the content of the data information can be determined to be more important, and the priority of the data information is improved; when the number of times of continuous automatic retransmission failure of the data information does not reach the preset value, the priority of the data information can be kept unchanged.
In an embodiment of the present invention, the data information may include at least one of the following: an Acknowledgement Character (ACK), a Negative Acknowledgement (ANCK), and other types of automatic retransmission data may also be included. The preset value may be a value specified in the communication protocol that is less than the maximum number of allowed consecutive automatic retransmission failures. For example, if the maximum allowed number of consecutive automatic repeat failure times specified in the communication protocol is 10, the preset value may be set to 8, or may be set to 9 or another value smaller than 10.
For example, the data information of the current SIM card is ACK, the maximum number of consecutive automatic retransmission failures allowed by ACK is specified in the communication protocol to be 15, and the preset value is set to be 12. And when the number of times of ACK continuous automatic retransmission failure reaches 12 times, the priority of the ACK is increased.
It can be understood that, in practical applications, other determination criteria may also exist to determine whether the priority of the data information can be adjusted, which is not described herein again.
In the embodiment of the present invention, after the priority adjustment of the data information is completed, step S103 may be executed.
Step S103, after the service priority of the data information is adjusted, the adjusted priority of the data information is compared with the priority of the service operation of other SIM cards.
In a specific implementation, after the priority adjustment of the data information of the current SIM card is completed, the priority of the adjusted data information may be compared with the priority of the service operation currently performed by another SIM card, and according to the comparison result, step S104 is performed.
And step S104, selecting the SIM card corresponding to the information with higher priority to process the information.
In specific implementation, when the priority of the adjusted data information of the current SIM card is higher than the priority of the service operation of other SIM cards, the current SIM card processes the data information. For example, when the data information is a data resource issued by the network side, the current SIM card receives the data resource sent by the network side. And when the data information is the data resource sent to the network side, the current SIM card sends the data resource to the network side.
And when the priority of the adjusted data information of the current SIM card is lower than the priority of the service operation of other SIM cards, the other SIM cards process the information. For example, if the priority of receiving the PCH of the other SIM card is higher than the adjusted priority of the data information of the current SIM card, the data information of the current SIM card is discarded from being processed, and the PCH is received by the other SIM card.
Therefore, when the time slot of the SIM card in the data transmission state for transmitting data conflicts with the time slots of other SIM cards for receiving the paging indication information, the priority of the data information transmitted by the current SIM card is adjusted. When the data information of the current SIM card is more important, the priority of the data information is increased, so that the mobile terminal receives the data information of the current SIM card and discards the paging indication information of other SIM cards, thereby avoiding that when service conflict occurs, the data information of the SIM card in a data transmission state is discarded because the priority is lower than the paging indication information of other SIM cards, and the data transmission rate is reduced.
In the embodiment of the present invention, after the priority of a certain data message is increased, if the high priority of the data message is continuously maintained and the priority of the data message is always higher than the priority of the service operation of other SIM cards, the service operation cannot be executed by other SIM cards for a long time, and a network drop situation may occur.
In order to avoid the above situation, in the embodiment of the present invention, after the priority of a certain data message is increased, when a certain condition is satisfied, the priority of the data message may also be decreased, so that a situation that another SIM card cannot perform a service operation for a long time may be avoided.
For example, when the number of times of automatic retransmission failure of ACK reaches a preset value, the priority of ACK is raised. When ACK retransmission is detected to be successful, the priority of the ACK is lowered.
In the embodiment of the present invention, a mapping table of uplink and downlink data information and priorities of different SIM cards may be set in a physical layer, and the priorities in the mapping table may be dynamically adjusted according to states of the uplink and downlink data information, and a specific adjustment rule may refer to step S102 in the above embodiment of the present invention, which is not described herein again.
The following describes, by way of example, a service conflict handling method provided in the foregoing embodiment of the present invention.
In practical application, when detecting that the number of times of ACK/NACK retransmission failure reaches a preset value in a Radio Link Control (RLC) layer or a Media Access Control (MAC) layer, in a preset priority mapping table in a physical layer, the priority corresponding to ACK/NACK is increased, so that the adjusted ACK/NACK priority is higher than the priority of other SIM cards for receiving PCH. And after the ACK/NACK retransmission is detected to be successful, the priority of the ACK/NACK is adjusted, so that the adjusted ACK/NACK priority is lower than the priority of other SIM cards for receiving PCH.
Referring to fig. 2, a schematic structural diagram of a service conflict processing apparatus 20 for a multi-card multi-standby mobile terminal in an embodiment of the present invention is shown, including: a detection unit 201, a judgment unit 202, an adjustment unit 203, a comparison unit 204 and a selection receiving unit 205, wherein:

In a specific implementation, the adjusting unit 203 may be configured to: and acquiring a subframe type corresponding to the data information, and increasing the priority of the data information when the number of subframes of the subframe type in the corresponding data frame is less than a preset value.
