Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

First embodiment

The embodiment of the invention provides a cell reselection method, which can be applied to a mobile terminal with N SIM cards, wherein the N SIM cards can be from the 1 st SIM card to the Nth SIM card, and N is a positive integer greater than 1; exemplarily, the mobile terminal may be a dual-card dual-standby mobile terminal, a three-card three-standby mobile terminal, or a four-card four-standby mobile terminal, etc.

When N is equal to 2, the dual-card dual-standby mobile terminal is provided with two same SIM card interfaces and two same high-level protocol stack processing modules, wherein one high-level protocol stack processing module serves one SIM card, and the two high-level protocol stack processing modules work independently and can share the physical layer module in a time-sharing manner.

When N is greater than 2, the implementation principle of the mobile terminal with N SIM cards is substantially the same as the implementation principle of the dual-card dual-standby mobile terminal described above, and details are not repeated here.

Here, the above-described mobile terminal may be a mobile phone, a tablet computer, a notebook computer, or the like.

Optionally, the mobile terminal described above may be connected to the internet, where the connection may be performed through a mobile internet network provided by an operator, or through a network connected to a wireless access point.

Here, if the mobile terminal has an operating system, the operating system may be UNIX, Linux, Windows, Android (Android), Windows Phone, or the like.

The following describes in detail the implementation of the embodiments of the present invention.

Fig. 3 is a flowchart of a cell reselection method according to an embodiment of the present invention, as shown in fig. 3, the flowchart may include:

step 301: and when the signal intensity of the current service cell and all the adjacent cells of the 1 st SIM card is smaller than the signal intensity threshold value, selecting at least one SIM card from the 2 nd SIM card to the Nth SIM card.

Here, the 1 st SIM card may be any one of the above-described N SIM cards, and the type of the 1 st SIM card is not limited in the embodiment of the present invention; it is understood that for a mobile terminal with N SIM cards, a serving cell and a neighbor cell may be determined for each SIM card.

For example, the determination manners of the neighbor cells of the N SIM cards may be the same.

In actual implementation, the mobile terminal may determine a neighbor cell list for each SIM card, and then may detect the signal strength of each neighbor cell in the neighbor cell list and the current serving cell of each SIM card; here, the signal strength is used to represent the quality of the signal received by the terminal from the corresponding cell, and may be, for example, the signal strength (Rxlevel) or the signal-to-noise ratio (Ec/Io) received by the mobile terminal.

In an embodiment, the mobile terminal may detect the signal strengths of the current serving cell and all neighboring cells of the 1 st SIM card every set time length, where the set time length may be set according to actual application requirements.

When the mobile terminal detects the signal intensity of the current service cell and all the adjacent cells of the 1 st SIM card, the size relation between the value of each detected signal intensity and the signal intensity threshold value needs to be judged, if the signal intensity of the current service cell and all the adjacent cells of the 1 st SIM card is smaller than the signal intensity threshold value, at least one SIM card can be selected from the 2 nd SIM card to the Nth SIM card; if the signal strength of the current serving cell of the 1 st SIM card is greater than or equal to the signal strength threshold, the mobile terminal may continue to camp on the current serving cell of the 1 st SIM card and not initiate cell reselection or handover; if the signal strength of the current serving cell of the 1 st SIM card is smaller than the signal strength threshold and the signal strength of any neighbor cell of the current serving cell of the 1 st SIM card is greater than or equal to the signal strength threshold, the mobile terminal may reselect to the neighbor cell of the 1 st SIM card.

Step 302: and detecting the signal strength of the current service cell of all the selected SIM cards.

In practical implementation, after determining the selected SIM card, the mobile terminal may detect the signal strength of the current serving cell for each selected SIM card.

Step 303: determining the SIM cards meeting the set conditions from all the selected SIM cards, wherein the set conditions are as follows: the signal strength of the current serving cell is greater than or equal to the signal strength threshold.

In practical implementation, the mobile terminal may determine a magnitude relationship between the signal intensity of each selected SIM card and a signal intensity threshold, and if there is an SIM card satisfying a set condition among the selected SIM cards, may execute step 304; if there is no SIM card satisfying the set condition among the selected SIM cards, the process may be directly ended.

Step 304: and adding the current service cell of the SIM card meeting the set conditions into the neighbor cell list of the 1 st SIM card, and controlling the 1 st SIM card to reselect the cell based on the new neighbor cell list.

Exemplarily, after the SIM card meeting the set condition is determined, whether the current serving cell of the SIM card meeting the set condition needs to be added to the neighbor list of the 1 st SIM card may be determined according to the cell identifier of the current serving cell of the SIM card meeting the set condition and the cell identifiers of all the neighbor cells of the initial neighbor list of the 1 st SIM card; if any one SIM card meeting the set conditions is marked as a specific SIM card, and the cell identification of the current service cell of the specific SIM card is different from the cell identifications of all the adjacent cells of the initial adjacent cell list of the 1 st SIM card, the current service cell of the specific SIM card can be added into the adjacent cell list of the 1 st SIM card; if any SIM card meeting the set conditions is marked as a specific SIM card, and the cell identifier of the current service cell of the specific SIM card is the same as the cell identifier of a neighboring cell of the initial neighboring cell list of the 1 st SIM card, the current service cell of the specific SIM card is not added into the neighboring cell list of the 1 st SIM card.

In practical applications, steps 301 to 304 may be implemented by a processor or the like in the mobile terminal.

When the cell reselection method of the embodiment of the invention is applied, firstly, when the signal intensity of the current service cell and all the adjacent cells of the 1 st SIM card is smaller than the signal intensity threshold value, at least one SIM card is selected from the 2 nd SIM card to the Nth SIM card; then, detecting the signal intensity of the current service cell of all selected SIM cards; determining the SIM cards meeting the set conditions from all the selected SIM cards, wherein the set conditions are as follows: the signal strength of the current serving cell is greater than or equal to a signal strength threshold; and finally, adding the current service cell of the SIM card meeting the set conditions into the neighbor cell list of the 1 st SIM card, and controlling the 1 st SIM card to perform cell reselection based on the new neighbor cell list.

Here, one SIM card may be selected from the 2 nd to nth SIM cards, or at least two SIM cards may be selected from the 2 nd to nth SIM cards.

In an embodiment, the mobile terminal may send a first prompt message to the user when determining that the signal strengths of the current serving cell and all neighboring cells of the 1 st SIM card are smaller than the signal strength threshold, so as to prompt the user to select at least one SIM card from the 2 nd SIM card to the nth SIM card.

After the user selects the SIM card, equivalently inputting first indication information to the mobile terminal to indicate the mobile terminal to select at least one SIM card; therefore, the mobile terminal can select at least one SIM card from the 2 nd SIM card to the Nth SIM card according to the received first indication information for selecting the SIM card.

In another embodiment, the mobile terminal may detect the signal strengths of the current serving cells of the 2 nd to nth SIM cards when determining that the signal strengths of the current serving cell of the 1 st SIM card and all neighboring cells are less than the signal strength threshold; then, M SIM cards with the highest signal intensity of the current service cell are selected from the 2 nd SIM card to the Nth SIM card, wherein M is an integer less than or equal to N-1.

Here, the value of M may be preset according to the actual application requirement.

Step A2: and detecting the signal strength of the current service cell of all the selected SIM cards.

Step A3: determining the SIM cards meeting the set conditions from all the selected SIM cards, wherein the set conditions are as follows: the signal strength of the current serving cell is greater than or equal to the signal strength threshold.

Step A4: and adding the current service cell of the SIM card meeting the set conditions into the neighbor cell list of the 1 st SIM card, and controlling the 1 st SIM card to reselect the cell based on the new neighbor cell list.

The implementation of step a2 to step a4 is the same as that of step 302 to step 304, and is not described here again.

In practical applications, the steps a1 to a4 may be implemented by a processor in the mobile terminal.

Third embodiment

A third embodiment of the present invention provides a further cell reselection method, where a flow of the cell reselection method in the third embodiment of the present invention may include:

Step B2: and detecting the signal strength of the current service cell of all the selected SIM cards.
