Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The base station may broadcast a System message for one or more cells, where the System message carries Information about a cell, for example, the System message SIB1(System Information Block Type1) corresponding to a certain cell may carry cell barring (cellBarred) Information, where the cell barring Information mainly has two states, one state is barred and indicates that the cell corresponding to the System message is a barring cell, and the other state is not barred and indicates that the cell corresponding to the System message is an allowed cell.
After receiving the system message, the terminal may determine which cells corresponding to the system message are cells prohibited from being accessed and which cells corresponding to the system message are messages allowed to be accessed by parsing the system message, so as to select a cell allowed to be accessed when selecting a cell to be accessed. For a terminal with multiple SIM cards, each SIM card can receive the system message and then analyze the system message respectively, which causes repeated analysis of the system message and results in waste of resources.
Fig. 1 is a schematic flow chart diagram illustrating a system message processing method according to an embodiment of the present disclosure. The method described in this embodiment may be applied to a terminal, where the terminal may communicate with a base station, for example, may communicate with the base station based on a 4G or 5G communication protocol, and a plurality of SIM cards are disposed in the terminal.
As shown in fig. 1, the system message processing method may include the steps of:
in step S1, a first SIM card of the plurality of SIM cards determines cell barring information for at least one cell;
in one embodiment, a first SIM card of the plurality of SIM cards may determine cell barring information for at least one cell, e.g., the first SIM card may receive a system message for the at least one cell when performing cell selection or cell reselection, and then parse the system message to determine the cell barring information for the at least one cell.
Specifically, the System message may include a MIB (Master Information Block) and multiple SIBs (System Information blocks), and the first SIM card may decode the MIB first and further decode the SIBs according to decoded parameters. The cell barring information can be obtained by decoding the SIB1 in the multiple SIBs, and based on the cell barring information, it can be determined whether the cell corresponding to the system message is a cell to which access is allowed or a cell to which access is prohibited.
In step S2, a second SIM card of the plurality of SIM cards determines a cell of the at least one cell to which access is barred based on the cell barring information;
it should be noted that, the first SIM card and the second SIM card do not refer to a certain SIM card of the multiple SIM cards, but refer to two different SIM cards of the multiple SIM cards. The steps that need to be executed by the first SIM card in the embodiments of the present disclosure may also be executed by the second SIM card.
In one embodiment, the first SIM card may send the cell barring information to the second SIM card, and the second SIM card determines, based on the cell barring information, a cell to which access is barred in the at least one cell; the first SIM card may also determine a cell prohibited from accessing in the at least one cell based on the cell barring information, and then send information of the cell prohibited from accessing to the second SIM card, for example, send an identifier of the cell prohibited from accessing to the second SIM card, and the second SIM card may determine the cell prohibited from accessing in the at least one cell based on the information of the cell prohibited from accessing.
In step S3, when performing cell selection or cell reselection, the second SIM card determines, among cells corresponding to the received system message, a cell that is allowed to access and is different from the cell that is prohibited to access;
in one embodiment, the second SIM card may receive system messages corresponding to a plurality of cells when performing cell selection (e.g., the second SIM card has just initiated cell access selection) or cell reselection (e.g., the second SIM card needs to switch cells). It should be noted that the system message received by the second SIM card may have different contents from the system message received by the first SIM card.
The second SIM card receives the system messages corresponding to the plurality of cells, before parsing the system messages, the cells corresponding to the system messages may be determined, and further, the cells corresponding to the system messages may be compared with the cells prohibited from being accessed, and a cell different from the cell prohibited from being accessed is determined in the cells corresponding to the system messages, that is, a cell permitted to be accessed.
In step S4, the second SIM card parses the system message corresponding to the cell allowed to access.
In one embodiment, for the system message corresponding to the cell to which access is prohibited, even if the analyzed result (e.g., the state of the cell barred) is that the cell to which the system message corresponds is prohibited from accessing, information about other cells (e.g., the communication quality of the cell) acquired by analyzing the system message cannot be used by the second SIM card to access the cell to which access is prohibited, which results in a waste of resources (e.g., power).
Therefore, after the second SIM card determines the cell allowed to be accessed in the cell corresponding to the received system message based on the cell barring information determined by the first SIM card, only the system message corresponding to the cell allowed to be accessed can be analyzed without analyzing the system message corresponding to the cell prohibited to be accessed, thereby avoiding resource waste caused by analyzing the system message corresponding to the cell prohibited to be accessed.
According to the embodiment of the disclosure, the second SIM card may receive the system message when performing cell selection or cell reselection, and may determine, based on the cell barring information determined by the first SIM card, a cell allowed to be accessed in the cell corresponding to the received system message, and then only analyze the system message corresponding to the cell allowed to be accessed, without analyzing the system message corresponding to the cell prohibited to be accessed, which is beneficial to avoiding waste of resources.
For example, the second SIM card determines that the cell a in at least one cell is a cell for which access is prohibited based on the cell barring information, and when cell selection or cell reselection is subsequently performed, the cells corresponding to the received system message may include a cell a and a cell B, and then, through comparison (for example, the cells prohibited from accessing may be stored in a list form, and then the cells corresponding to the system message may be compared with the cells in the list one by one), it is known that the cell a is a cell prohibited from accessing, the cell B is a cell allowed to access, therefore, only the system message corresponding to the cell B can be analyzed to obtain the information about the cell B, so as to access the cell B according to the information about the cell B (or when there are a plurality of cells allowed to access, one cell can be selected to access according to the information about the plurality of cells allowed to access), without analyzing the system message corresponding to the cell a.
It should be noted that the second SIM card does not analyze the system message corresponding to the cell prohibited from being accessed, may not analyze the MIB or the SIB in the system message, or may analyze the MIB and not analyze the SIB in the system message, and may be specifically configured by the base station.
In addition, under the condition that the SIM card of one operator can access cells in networks of different operators, the first SIM card and the second SIM card can be SIM cards of different operators or SIM cards of the same operator; in the case where the SIM card of one operator network can only access the operator network, the first SIM card and the second SIM card need to be SIM cards of the same operator network to ensure that the cell barring information determined by the first SIM card is also applicable to the cells accessible by the second SIM card.
Fig. 2 is a schematic flow chart diagram illustrating another system message processing method according to an embodiment of the present disclosure. As shown in fig. 2, the determining, by the second SIM card, the cell to which access is barred in the at least one cell based on the cell barring information includes:
in step S21, the first SIM card sends the cell barring information to the second SIM card;
in step S22, the second SIM card determines a cell prohibited from accessing in the at least one cell according to the cell prohibition information.
In one embodiment, the first SIM card may send the cell barring information to the second SIM card, and the second SIM card determines, based on the cell barring information, a cell to which access is barred in the at least one cell.
Fig. 3 is a schematic flow chart diagram illustrating yet another system message processing method according to an embodiment of the present disclosure. As shown in fig. 3, the method further comprises:
in step S5, the first SIM card determines whether the cell barring information of the at least one cell acquired last time is the same as the cell barring information of the at least one cell acquired last time;
in step S6, if the cell barring information of the at least one cell acquired last time is different from the cell barring information of the at least one cell acquired last time, the first SIM card sends the cell barring information of the at least one cell acquired last time to the second SIM card.
In an embodiment, the first SIM card may periodically receive the system message, and parse the system message to obtain the cell barring information, and may compare whether the cell barring information of the at least one cell obtained last time is the same as the cell barring information of the at least one cell obtained last time.
If the cell access permission state is different, it is indicated that the cell access permission state is changed, the cell barring information of the at least one cell acquired last time may be sent to the second SIM card, so that the second SIM card can accurately determine which cells are cells to which access is prohibited according to the cell barring information of the at least one cell acquired last time.
Fig. 4 is a schematic flow chart diagram illustrating yet another system message processing method according to an embodiment of the present disclosure. As shown in fig. 4, the determining, by the second SIM card, the cell to which access is barred in the at least one cell based on the cell barring information includes:
in step S23, the first SIM card determines a cell prohibited from accessing in the at least one cell according to the cell prohibition information;
in step S24, the first SIM card sends information of the cell to which access is prohibited to the second SIM card;
in step S25, the second SIM card determines a cell prohibited from accessing in the at least one cell according to the information of the cell prohibited from accessing.
In one embodiment, the first SIM card may also determine a cell prohibited from accessing in the at least one cell based on the cell barring information, and then send information of the cell prohibited from accessing to the second SIM card, for example, send an identifier of the cell prohibited from accessing to the second SIM card, and the second SIM card may determine the cell prohibited from accessing in the at least one cell based on the information of the cell prohibited from accessing.
Fig. 5 is a schematic flow chart diagram illustrating yet another system message processing method according to an embodiment of the present disclosure. As shown in fig. 5, the method further comprises:
in step S7, the first SIM card determines whether the cell barring information of the at least one cell acquired last time is the same as the cell barring information of the at least one cell acquired last time;
in step S8, if the cell barring information of the at least one cell acquired last time is different from the cell barring information of the at least one cell acquired last time, the first SIM card determines a cell prohibited from being accessed in the at least one cell according to the cell barring information of the at least one cell acquired last time.
In an embodiment, the first SIM card may periodically receive the system message, and parse the system message to obtain the cell barring information, and may compare whether the cell barring information of the at least one cell obtained last time is the same as the cell barring information of the at least one cell obtained last time.
If the difference indicates that the state of the cell allowed to access is changed, the first SIM card may determine a cell prohibited from accessing in the at least one cell according to the cell barring information of the at least one cell acquired last time, and then update the information of the cell prohibited from accessing, so that the second SIM card can accurately determine which cells are cells prohibited from accessing according to the updated information of the cell prohibited from accessing.
Fig. 6 is a schematic flow chart diagram illustrating yet another system message processing method according to an embodiment of the present disclosure. As shown in fig. 6, the determining, by the first SIM card of the plurality of SIM cards, the cell barring information of the at least one cell includes:
in step S11, when the first SIM card performs cell selection or cell reselection, the first SIM card determines cell barring information of at least one cell according to the received system message.
In one embodiment, the first SIM card may receive a system message for at least one cell upon cell selection or cell reselection, and then parse the system message to determine cell barring information for the at least one cell.
Fig. 7 is a schematic flow chart diagram illustrating yet another system message processing method according to an embodiment of the present disclosure. As shown in fig. 7, the method further comprises:
in step S9, if the second SIM card parses the system message corresponding to the cell allowed to access, it is determined that there is a cell prohibited from accessing the cell allowed to access, and an indication message for updating the cell prohibition information is sent to the first SIM card.
In one embodiment, the first SIM card may periodically receive the system message, but the period of receiving the system message may be different from the period of the state change of the cell allowed access, which may cause the first SIM card to receive the system message and parse the obtained cell barring information last time, and to receive the system message and parse the obtained cell barring information next time, for example, where a certain cell is changed from allowed access to forbidden access, but the first SIM card does not know which cell is changed from allowed access to forbidden access because it does not receive the system message next time.
And the second SIM card can determine whether cells forbidden to access exist in the cells allowed to access by analyzing the system message corresponding to the cells allowed to access, and if so, it indicates that the cells in at least one cell are changed from allowed access to forbidden access, but the first SIM card does not know, so that an indication message for updating cell forbidden information can be sent to the first SIM card, so that the first SIM card can determine which cells are changed from allowed access to forbidden access in time.
