Specific embodiments of the present disclosure have been shown by way of example in the drawings and will be described in more detail below. The drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the disclosed concepts to those skilled in the art by reference to specific embodiments.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the embodiments of the present application, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated object, indicating that there may be three relationships, for example, a and/or B, which may indicate: a exists singly, A and B exist simultaneously, and B exists singly, wherein A and B can be singular or plural. In the written description of this application, the character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The technical scheme provided by the embodiment of the application can be applied to the dual-card terminal, and particularly can be applied to a scene that the dual-card terminal sharing the same radio frequency channel returns to a cell. When the dual card terminal makes a call through one of the cards, the dual card terminal falls back into a 3rd-Generation (3G) network through a Circuit Switched Fallback (CSFB), and during the call, the other card is suspended, i.e., the service of the card is suspended. In the following description, a card for making a call may be referred to as a telephone card, and another card to be hung may be referred to as a non-telephone card.

After the call is finished, the non-telephone card returns to the cell through the network selection operation, and the telephone card also quickly returns to a Long Term Evolution (LTE) cell. Taking a telephone card as a card 0 and a non-telephone card as a card 1 as an example, the specific process is as follows: the protocol layer of the terminal indicates the card 1 to return to the cell in the same subframe in sequence and indicates the card 0 to quickly return (fast return) to the LTE cell; the terminal physical layer processes according to the message sequence, firstly marks the card 1 as a dispatching card, and controls the card 1 to return to the cell through network selection operation. As shown in table 1 below, the control card 1 may first perform a network searching operation, which may be implemented by Initial Cell Search (ICS), parsing of a Master system Information Block (MIB), and measuring of Reference Signal Receiving Power (RSRP), and during the network searching operation performed by the control card 1, the card 0 is in a waiting state; after acquiring an indication card 0 indicating fast return (fast return) LTE cell, a physical layer of the terminal marks the card 0 as a scheduling card, acquires a plurality of pieces of frequency point information which are arranged in a sequence from strong to weak, and then executes a network searching operation by a control card 0 according to the plurality of pieces of frequency point information, wherein the network searching operation can also be realized by ICS, analysis MIB and measurement RSRP, but because the service priority of the system configuration information of the cell to be executed by the card 1 is higher than that of the network searching service of the card 0, the physical layer can also support the card 1 to acquire the system configuration information of the cell and return to the cell according to the acquired system configuration information; the control card 1 can acquire the System configuration Information of the cell by analyzing a System Information Block (SIB) 1 and an SIB 2; then, the control card 0 executes a network searching operation according to the multiple pieces of frequency point information, and acquires system configuration information of the LTE cell, so that the LTE cell is quickly returned (Fast return) according to the acquired system configuration information of the LTE cell. The control card 0 may also obtain the system configuration information of the LTE cell by analyzing SIB1 and analyzing SIB 2.

TABLE 1

However, based on the existing cell return method, the time delay for the card 0 to quickly return to the LTE cell is long. Therefore, how to reduce the time delay for the card 0 to quickly return to the LTE cell is an urgent problem to be solved by those skilled in the art.

In order to reduce the time delay for the card 0 to return to the LTE cell quickly, the physical layer of the terminal may consider that after receiving a message sent by the protocol layer of the terminal that the indication card 1 returns to the LTE cell, the physical layer first executes a network searching operation by using a preset time delay control card 1, and when receiving a message sent by the protocol layer of the terminal that the indication card 0 returns to the LTE cell, the physical layer preferentially controls the card 0 to return to the LTE cell.

Based on the technical concept, the embodiment of the application provides a method for rapidly returning to a Long Term Evolution (LTE) cell, which can be applied to a dual-card terminal, wherein the dual cards share one radio frequency channel. When the identity recognition card in the dual-card terminal is controlled to return to the cell, when a first indication message for executing cell returning operation on the first identity recognition card is obtained, the operation of obtaining a second indication message is executed within a preset time length; the second indication message is used for indicating that the second identity identification card is subjected to the operation of returning to the LTE cell quickly; when the second indication message is acquired, the second identity identification card is preferentially controlled to return to the LTE cell quickly according to the second indication message; the second identification card is the identification card which just ends the call operation.

The second identification card is the identification card which just ends the call operation, namely the card 1 in table 1, and the first identification card is the identification card which is suspended when the call is made through the second identification card, namely the card 0 in table 1.

It can be seen that, in the embodiment of the present application, when an identity card in a dual-card terminal is controlled to return to a cell, when a first indication message for performing a cell return operation on the first identity card is obtained, the first identity card is controlled to perform a network search operation by delaying for a preset time duration, and an operation for obtaining a second indication message is performed within the preset time duration; the second indication message is used for indicating that the second identity identification card is subjected to the operation of returning to the LTE cell quickly; when the second indication message is obtained, the second identity identification card is preferentially controlled to return to the LTE cell quickly according to the second indication message; therefore, the longer time delay of the second identity card to quickly return to the LTE cell caused by waiting for the first identity card to execute the cell returning operation can be avoided, and the time delay of the second identity card to quickly return to the LTE cell is effectively reduced.

Hereinafter, the method for fast returning to an LTE cell provided by the present application will be described in detail through specific embodiments. It is to be understood that the following detailed description may be combined with the accompanying drawings, and that the same or similar concepts or processes may not be described in detail in connection with certain embodiments.

Fig. 1 is a flowchart illustrating a method for quickly returning to an LTE cell according to an embodiment of the present disclosure, where the method for quickly returning to an LTE cell may be executed by a software and/or hardware device, and may be applied to a dual card terminal, where the dual cards share a radio frequency channel. For example, please refer to fig. 1, the method for fast returning to an LTE cell may include:

s101, when a first indication message for returning to a cell operation of a first identity identification card is acquired, executing an operation of acquiring a second indication message within a preset time length; the second indication message is used for indicating that the operation of quickly returning to the LTE cell is executed on the second identity card.

For a dual-card terminal sharing the same radio frequency channel, when the dual-card terminal makes a call through one of the cards, the card can be marked as a second identification card, the second identification card can fall back into the 3G network through the CSFB, in the process of a call, the other card can be hung up, the card can be marked as a first identification card, and the service of the first identification card can be suspended. When a protocol layer of the terminal detects that a second identity card finishes a call operation, a first indication message of returning the first identity card to the cell is sent to a physical layer of the terminal in the same subframe, and the second identity card executes a second indication message of quickly returning the second identity card to the LTE cell, so that the physical layer controls the first identity card to return to the cell and the second identity card to quickly return to the LTE cell. Normally, the first indication message is sent to the physical layer of the terminal before the second indication message.

In the embodiment of the present application, in order to preferentially control the second identification card to quickly return to the LTE cell, so as to solve a problem in the prior art that a time delay for the second identification card to quickly return to the LTE cell is long, when a first indication message for performing a cell return operation on a first identification card is obtained, the first identification card may not be controlled to perform a network search operation, but the first identification card may be delayed from performing the network search operation by a preset time length, and an operation of obtaining a second indication message may be performed within the preset time length.

For example, when the network searching operation is executed by delaying the first identification card by a preset time length, a timer may be set in a physical layer in advance, and when a first indication message for executing a cell returning operation on the first identification card is acquired, the timer is started, where the time length of the timer is the preset time length, the preset time length delays the first identification card from executing the network searching operation, and the operation of acquiring the second indication message is executed before the timer is overtime, so that when a second indication message for executing an LTE cell fast returning operation on the second identification card is acquired, the second identification card may be preferentially controlled to return to the LTE cell fast according to the second indication message, that is, the following S102 is executed.

For example, when the preset time duration is determined, the preset time duration may be determined according to the time required from the acquisition of the first indication message to the acquisition of the second indication message, as long as the preset time duration is enough for a physical layer of the terminal to acquire the second indication message for performing the operation of quickly returning to the LTE cell on the second identity card. For example, the preset time may be 1ms or 2ms, and since the message interval between the physical layer and the physical layer for acquiring the first indication message and the second indication message is less than 1ms, the preset time is set as long as the preset time is greater than 1 ms.

S102, when the second indication message is obtained, the second identity identification card is controlled to return to the LTE cell quickly according to the second indication message in a priority mode; the second identification card is an identification card which just ends the call operation.

It can be seen that, in the embodiment of the present application, when an identity card in a dual-card terminal is controlled to return to a cell, when a first indication message for performing a cell return operation on the first identity card is obtained, the first identity card is controlled to perform a network search operation by delaying for a preset time duration, and an operation for obtaining a second indication message is performed within the preset time duration; the second indication message is used for indicating the second identity identification card to perform the operation of quickly returning to the LTE cell; when the second indication message is obtained, the second identity identification card is preferentially controlled to return to the LTE cell quickly according to the second indication message; therefore, the longer time delay for the second identity card to quickly return to the LTE cell caused by waiting for the first identity card to execute the cell returning operation can be avoided, and the time delay for the second identity card to quickly return to the LTE cell is effectively reduced.

Based on the embodiment shown in fig. 1, when the second identification card is preferentially controlled to return to the LTE cell in S102, for example, the second identification card may be preferentially controlled to return to the LTE cell in at least two possible implementation manners described below, so as to avoid that the time delay for the second identification card to return to the LTE cell quickly is long due to waiting for the first identification card to perform the operation of returning to the cell, thereby effectively reducing the time delay for the second identification card to return to the LTE cell quickly.

In a possible implementation, when the second identification card is preferentially controlled to return to the LTE cell quickly, the second identification card may be controlled to return to the LTE cell quickly, and the first identification card may be controlled to be in a waiting state; and after the second identification card quickly returns to the LTE cell, controlling the first identification card to return to the cell.

With reference to the description in table 1, the specific process is as follows, taking the phone card as card 0 and the non-phone card as card 1 as examples: the protocol layer of the terminal indicates the card 1 to return to the cell in the same subframe in sequence and indicates the card 0 to quickly return (fast return) to the LTE cell; the terminal physical layer processes according to the message sequence, firstly marks the card 1 as a dispatching card, and controls the card 1 to return to the cell through network selection operation. As shown in table 2 below, when receiving a first indication message for performing a cell return operation on the card 1, starting a timer for delaying the execution of a network search operation by the first identity card, and controlling the execution of an operation for acquiring a second indication message for performing a fast cell return operation on the card 0 within a preset time period after the timer is started, and when acquiring the second indication message, because the card 1 is delayed, the physical layer immediately responds to an RSSI _ SYNC message of the card 0 and marks the card 0 as a scheduling card, even if the timer is over, because the scheduling card is the card 0, the card 1 is always in a waiting state, and first the card 0 performs a network search operation according to the RSSI _ SYNC message, which can be implemented by analyzing a control card and measuring RSRP, and during the ICS network search operation performed by the card 0, the card 1 is in a waiting state; continuously keeping the card 0 as a scheduling card, and executing, by the control card 0, acquisition of system configuration information of the LTE cell, wherein the acquisition of the system configuration information of the cell by the control card 0 can be realized by analyzing SIB1 and analyzing SIB2, and during the execution of the acquisition of the system configuration information of the LTE cell by the control card 0, the control card 1 is in a waiting state, and further, the control card 0 quickly returns to the LTE cell according to the acquired system configuration information of the LTE cell, executes a TAU procedure, and during this period, continuously keeping the control card 1 in the waiting state; after determining that the control card 0 finishes executing the TAU flow, the card 1 can be marked as a scheduling card, the control card 1 executes a network searching operation, the network searching operation can also be realized by ICS, analysis MIB and measurement RSRP, and after the network searching operation is finished, the control card 1 continues to execute and acquire system configuration information of a cell, wherein the system configuration information of the cell acquired by the control card 1 can also be realized by analyzing SIB1 and analyzing SIB2, and the control card 1 returns to the cell according to the acquired system configuration information of the cell, so that the control card 0 can be preferentially returned to the LTE cell quickly, the long time delay of the card 2 returning to the LTE cell quickly caused by waiting for the card 1 to execute the cell returning operation is avoided, and the time delay of the card 2 returning to the LTE cell is effectively reduced.

TABLE 2

It can be seen that, in this possible implementation manner, when the identity card in the dual-card terminal is controlled to return to the cell, and when the first indication message for performing the cell return operation on the first identity card is obtained, the first identity card is controlled to perform the network searching operation by delaying for a preset time duration, and the operation of obtaining the second indication message is performed within the preset time duration; the second indication message is used for indicating the second identity identification card to perform the operation of quickly returning to the LTE cell; when the second indication message is acquired, the second identification card is preferentially controlled to quickly return to the LTE cell, and the first identification card is controlled to be in a waiting state; after the second identity recognition card quickly returns to the LTE cell, controlling the first identity recognition card to return to the cell; therefore, the longer time delay for the second identity card to quickly return to the LTE cell caused by waiting for the first identity card to execute the cell returning operation can be avoided, and the time delay for the second identity card to quickly return to the LTE cell is effectively reduced.

In another possible implementation manner, when the second identification card is preferentially controlled to return to the LTE cell quickly, the first identification card may be controlled to perform a network searching operation first during the period of controlling the second identification card to return to the LTE cell quickly; and after controlling the second identity card to quickly return to the LTE cell, controlling the first identity card to acquire the system configuration information of the cell and returning to the cell according to the system configuration information of the cell.

For example, when the first identification card is controlled to perform the network searching operation during the period of controlling the second identification card to quickly return to the LTE cell, the second identification card may be marked as a scheduling card, the second identification card is controlled to perform the network searching operation, and the first identification card is controlled to be in a waiting state; during the period of controlling the second identity identification card to acquire the system configuration information of the LTE cell, marking the first identity identification card as a scheduling card, and controlling the first identity identification card to execute network searching operation; the service priority of the system configuration information is higher than that of the first identity card network searching operation; and controlling the second identity recognition card to quickly return to the LTE cell according to the system configuration information of the LTE cell.

With reference to the description in table 1, taking the phone card as card 0 and the non-phone card as card 1 as an example, the specific process is as follows: the protocol layer of the terminal indicates the card 1 to return to the cell in the same subframe in sequence, and indicates the card 0 to return to (fast return) the LTE cell quickly; the terminal physical layer processes according to the message sequence, firstly marks the card 1 as a dispatching card, and controls the card 1 to return to the cell through network selection operation. As shown in table 3 below, when a first indication message for performing a cell return operation on the card 1 is received, the timer is controlled to start, so as to delay the first identity card to perform a network searching operation, for example, please refer to fig. 2, fig. 2 is a schematic flow diagram of the card 0 and the card 1 returning to the cell provided in the embodiment of the present application, and the operation of obtaining a second indication message for performing a fast LTE cell return operation on the card 0 is controlled to be performed within a preset time period after the timer is started, and when the second indication message is obtained, since the card 1 is delayed, the physical layer immediately responds to a SYNC _ SYNC message of the card 0 and marks the card 0 as a scheduling card, even if the timer is overtime, since the scheduling card is the card 0, the card 1 is always in a waiting state, first 0 performs a network searching operation according to the SYNC _ SYNC message of the RSSI, the network searching operation can be implemented by ICS, parsing MIB and measuring RSRP, and during the network searching operation of the control card 1 is performed in a waiting state; after the card 1 finishes the network searching operation, marking the card 1 as a scheduling card, and executing the network searching operation by the control card 1, wherein the network searching operation can also be realized by ICS, analysis MIB and measurement RSRP, but because the service priority of the system configuration information of the LTE cell executed by the card 0 is higher than the priority of the network searching operation executed by the card 1, the physical layer firstly obtains the system configuration information of the LTE cell by the control card 0, the system configuration information of the LTE cell can be obtained by analyzing SIB1 and analyzing SIB2, and during the period of executing the system configuration information of the LTE cell by the control card 0, the control card 1 is inserted to empty to execute the network searching operation, and then the control card 0 rapidly returns to the LTE cell according to the obtained system configuration information of the LTE cell and executes TAU flow, and during the period, the control card 1 is continuously in a waiting state; after the TAU flow is determined to be executed by the control card 0, the control card 1 continues to execute the system configuration information of the acquired cell, wherein the system configuration information of the cell acquired by the control card 1 can be realized by analyzing the SIB1 and analyzing the SIB2, and the control card 1 returns to the cell according to the acquired system configuration information of the cell, so that the control card 0 can be preferentially and quickly returned to the LTE cell, and the long time delay of the card 0 quickly returning to the LTE cell caused by waiting for the card 1 to execute the cell returning operation is avoided, so that the time delay of the card 0 quickly returning to the LTE cell is effectively reduced.

TABLE 3

It can be seen that, in this possible implementation manner, when the identity card in the dual-card terminal is controlled to return to the cell, and when the first indication message for performing the cell return operation on the first identity card is obtained, the first identity card is controlled to perform the network searching operation by delaying for a preset time duration, and the operation of obtaining the second indication message is performed within the preset time duration; the second indication message is used for indicating the second identity identification card to perform the operation of quickly returning to the LTE cell; when the second indication message is acquired, the first identification card is controlled to execute network searching operation in a plugging-in mode during the period that the second identification card is controlled to quickly return to the LTE cell; after the second identity identification card is controlled to quickly return to the LTE cell, the first identity identification card is controlled to acquire cell system configuration information and returns to the cell according to the cell system configuration information; therefore, the longer time delay for the second identity card to quickly return to the LTE cell caused by waiting for the first identity card to execute the cell returning operation can be avoided, and the time delay for the second identity card to quickly return to the LTE cell is effectively reduced.
