DETAILED DESCRIPTION

Embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the disclosure as recited in the appended claims.

The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to limit the present disclosure. As used in this disclosure and the appended claims, the singular forms “a,” “the,” and “the” are intended to include the plural forms as well, unless the context clearly dictates otherwise. It will also be understood that the term “and/or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various pieces of information, such information should not be limited by these terms. These terms are only used to distinguish the same type of information from each other. For example, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information, without departing from the scope of the present disclosure. Depending on the context, the word “if” as used herein can be interpreted as “at the time of” or “when” or “in response to determining.”

Different terminal behaviors and processing methods may lead to many multi-card problems in multi-card terminals. In the embodiments of the present disclosure, the multi-card terminal may have but not limited to the following multi-card problems:

Problem 1. When the multi-card terminal communicates with the first system through one of the SIM cards, the multi-card terminal needs to keep monitoring the second system, including but not limited to monitoring paging messages, performing system measurements, and reading the system messages etc. This may affect the communication performance of the first system.

Problem 2. The paging timing is calculated according to the terminal identifier, and the multi-card terminal has multiple SIM cards, so the corresponding paging timings between different SIM cards may be the same, resulting in systematic paging collisions.

Problem 3. When the multi-card terminal communicates with the first system through one of the SIM cards, the other SIM card monitors the paging message from the second system, and the multi-card terminal needs to decide whether to perform a paging response. At present, whether to perform a paging response is based on the rules configured by the user.

Problem 4: When the multi-card terminal determines to respond to the paging message of the second system, it needs to stop the service currently being performed in the first system. If there is no suspension mechanism for the current service, the multi-card terminal will automatically disconnect the RRC (Radio Resource Control) connection with the first system and leave the first system. After the multi-card terminal leaves the first system, the first system will continue to page the multi-card terminal, resulting waste of paging resources.

Problem 5. When the terminal reads paging or system measurement in the second system, it will cause a short interval in the first system, and the duration is generally about 20 ms (milliseconds), but for the first system, it is equivalent to experiencing shadow fading (in mobile communication, due to the shadow effect caused by obstacles, the received signal strength decreases, but the median value of the field strength changes slowly with geographical changes, also known as slow fading). Since a short interval occurs once in each paging cycle, the power control and link adaptation algorithms of the network may be affected, resulting waste of resources of the first system.

Problem 6. When the terminal determines to switch to the cell of the second system, it needs to read the system information in the second system, resulting in a long interval of the first system. The duration is generally about 1 second. The first system may consider the long interval as an error condition. In the related art, neither the base station nor the terminal can handle this situation.

Problem 7. In the process of the terminal performing TAU (Tracking Area Update) in the second system, a longer interval for the first system may be caused. The duration may reach several seconds, resulting in a greater impact on the first system.

In order to reduce the above-mentioned multi-card problem existing in the multi-card terminal and make the cell selection method more flexible, the present disclosure provides the following cell selection scheme.

First, the cell selection method provided by the present disclosure will be described from the base station side.

An embodiment of the present disclosure provides a cell selection method. Referring to FIG. 1, FIG. 1 is a flowchart of a cell selection method according to an embodiment, which can be used for a base station, the base station is a base station connected to a multi-card terminal, or a base station where the multi-card terminal resides, the method may include the following steps.

In step 101, target capability information corresponding to at least one neighbor base station is acquired.

In some embodiments of the present disclosure, the target capability information is used to indicate the capability of solving the multi-card problems of the multi-card terminal, and the multi-card problems include but are not limited to the above seven multi-card problems.

In some embodiments of the present disclosure, the base station and the neighbor base station may be base stations of the same standard, or base stations of different standards, which are not limited in the present disclosure. In an embodiment, the base station and at least one neighbor base station may be NR (New Radio) base stations. In another embodiment, the base station may be an NR base station, and at least one neighbor station may be an EUTRAN (Evolved Universal Terrestrial Radio Access Network) base station.

In this embodiment of the present disclosure, the base station may acquire target capability information corresponding to at least one neighbor base station through an inter-base station interface, including but not limited to an X2 or Xn interface.

In step 102, the target capability information corresponding to the at least one neighbor base station is sent.

In the above embodiment, the base station may acquire and send target capability information corresponding to at least one neighbor base station, wherein the target capability information may be used to indicate the capability of solving the multi-card problems of the multi-card terminal. The multi-card terminal can at least perform cell selection based on the target capability information corresponding to the neighbor base station. In the present disclosure, the multi-card problems of the multi-card terminal can be reduced, the cell selection method is more flexible, and the usability is high.

In some embodiments, referring to FIG. 2, FIG. 2 is a flowchart of a cell selection method according to an embodiment, and the method may include the following steps.

In step 201, the target capability information corresponding to the at least one neighbor base station is broadcast through broadcast signaling.

In the embodiment of the present disclosure, regardless of whether the multi-card terminal is in a connected state, an idle state or an inactive state, the base station can broadcast the target capability information corresponding to the at least one neighbor base station through broadcast signaling. The multi-card terminal acquires target capability information corresponding to at least one neighbor base station by receiving broadcast signaling.

In the above embodiment, the base station can broadcast the target capability information corresponding to at least one neighbor base station through broadcast signaling, so that the multi-card terminal can subsequently perform cell selection at least according to the target capability information corresponding to the neighbor base station, which is easy to implement and has high availability.

In some embodiments, the broadcast signaling may be used to broadcast a target system message carrying target capability information corresponding to the at least one neighbor base station. The base station can send the target system message carrying the target capability information corresponding to at least one neighbor base station to the multi-card terminal through the broadcast signaling.

In some embodiments, the target system message broadcast by the base station includes but is not limited to at least one of the following: SIB (System Information Block) 3, SIB4, SIB5, and SIB11. The base station broadcasts a target system message carrying target capability information corresponding to at least one neighbor base station, so that the multi-card terminal can perform cell selection.

In an embodiment of the present disclosure, the base station can add target capability information corresponding to the neighbor base station by modifying the target system message. Taking the modification of SIB3 as an example, the following information can be added to SIB3.

--- ASN1START
--- TAG-SIB3-START
SIB3 ::=            SEQUENCE {
...,
[[
Musimcapability-r17 MUSIMCapability-r17
OPTIONAL, -- Need R
]]
}

The manner of adding the target capability information corresponding to the neighbor base station in other SIB is similar, and details are not repeated here.

In the above embodiment, the target system message can be modified to carry the target capability information corresponding to the neighbor base station, which is simple to implement and has high availability.

In some embodiments, referring to FIG. 3, FIG. 3 is a flowchart of a cell selection method according to an embodiment, and the method may include the following steps.

In step 301, in response to determining that the multi-card terminal is in a connected state, the target capability information corresponding to the at least one neighbor base station is sent to the multi-card terminal through unicast signaling.

In the embodiment of the present disclosure, the base station may send the target capability information corresponding to at least one neighbor base station to the multi-card terminal through unicast signaling when it is determined that the multi-card terminal is connected to the base station, that is, the multi-card terminal is in the connected state.

In the above-mentioned embodiment, the base station may send the target capability information corresponding to at least one neighbor base station to the multi-card terminal through unicast signaling, so that the multi-card terminal can subsequently perform cell selection at least according to the target capability information corresponding to the neighbor base station, which is simple to implement and high availability.

In some embodiments, the base station may add the target capability information corresponding to at least one neighbor base station in the original first information element of the unicast signaling, and send the unicast information to the multi-card terminal.

And/or the base station may add a new second information element to the unicast signaling, and use the second information element to individually indicate target capability information corresponding to at least one neighbor base station, and then send the unicast signaling to the multi-card terminal.

In the embodiment of the present disclosure, the unicast signaling includes but is not limited to RRC Reconfiguration (Radio Resource Control Reconfiguration) signaling.

In the above embodiment, when the multi-card terminal is in the connected state, the base station can send the target capability information corresponding to the neighbor base station to the multi-card terminal through the information element in the unicast signaling, which is simple to implement and has high availability.

In some embodiments, the target capability information may be used to indicate the capability of the neighbor base station to solve the multi-card problem that may exist on the multi-card terminal, that is, the neighbor base station does not consider the actual multi-card problems of the multi-card terminal, and only provide the multi-card problem of the multi-card terminal that can be solved by itself to the base station where the multi-card terminal resides or has been accessed.

In some embodiments, the neighbor base station may indicate whether it has the ability to solve the corresponding multi-card problem respectively through, but not limited to, the bit value corresponding to 7 bits. Each bit sequence corresponds to above-mentioned one multi-card problem. The bit value corresponding to the bit is a first preset value, for example, the first preset value may be 1, and it is determined that the neighbor base station has the ability to solve the multi-card problem. The bit value corresponding to the bit is a second preset value, for example, the second preset value may be 0, and it is determined that the neighbor base station does not have the ability to solve the multi-card problem.

For example, the target capability information of a certain neighbor base station is represented by 7 bits as 1100110, which can be used to indicate that the neighbor base station can solve problem 1, problem 2, problem 5, and problem 6 in the above multi-card problem.

After the base station where the multi-card terminal resides or has accessed acquires the target capability information corresponding to the neighbor base station, it can send the target capability information corresponding to the neighbor base station through broadcast signaling or unicast signaling, so that the multi-card terminal can subsequently perform cell selection at least according to the target capability information corresponding to the neighbor base station.

In the above embodiment, the base station can acquire and send target capability information corresponding to at least one neighbor base station, so that the multi-card terminal can subsequently perform cell selection at least according to the target capability information corresponding to the neighbor base station, with high availability.

Next, the cell selection method provided by the present disclosure will be described from the multi-card terminal side.

An embodiment of the present disclosure provides a cell selection method. Referring to FIG. 4, FIG. 4 is a flowchart of a cell selection method according to an embodiment, which can be used for a multi-card terminal. The method may include the following steps.

In step 401, target capability information corresponding to at least one neighbor base station is received.

In the embodiment of the present disclosure, the multi-card terminal may receive target capability information corresponding to at least one neighbor base station sent by the base station through broadcast signaling or unicast signaling. Wherein, the target capability information is used to indicate the capability of solving the multi-card problem of the multi-card terminal.

In step 402, cell selection is performed at least based on the target capability information.

In the above embodiment, the multi-card terminal can at least perform cell selection according to the target capability information corresponding to at least one neighbor base station sent by the base station, thereby reducing the multi-card problem of the multi-card terminal, making the cell selection method more flexible and highly available.

In some embodiments, referring to FIG. 5, FIG. 5 is a flowchart of a cell selection method according to an embodiment, and the method may include the following steps.

In step 501, cell selection is performed based on the matching degree between the target capability information and the target multi-card problem of the multi-card terminal.

In the embodiment of the present disclosure, the target multi-card problem is the existing multi-card problem of the multi-card terminal, that is, the target multi-card problem is a multi-card problem that the multi-card terminal has actually experienced. The multi-card terminal can perform cell selection based on the matching degree between the target capability information corresponding to at least one neighbor base station and the target multi-card problem that it has experienced. The number of the target multi-card problems can be one or more.

In an embodiment of the present disclosure, the multi-card terminal can make the neighbor base station capable of solving the target multi-card problem indicated by the target capability information as the target base station. During cell selection, handover to the target base station is selected.

In another embodiment, all neighbor base stations cannot solve all the target multi-card problems, so the multi-card terminal can select the neighbor base station that can solve the most target multi-card problems as the target base station, so that when performing cell selection, handover to the target base station is selected.

In the above embodiment, the multi-card terminal can perform cell selection based on the target capability information corresponding to the neighbor base stations, thereby reducing the multi-card problem of the multi-card terminal, and making the cell selection method more flexible and highly available.

In some embodiments, referring to FIG. 6, FIG. 6 is a flowchart of a cell selection method according to an embodiment, and the method may include the following steps.

In step 601, cell selection is performed based on the matching degree between the target capability information and the target multi-card problem of the multi-card terminal and/or other cell selection factors. That is to say, cell selection is performed based on at least one of the matching degree between the target capability information and the target multi-card problem of the multi-card terminal and other cell selection factors.

In the embodiment of the present disclosure, the target multi-card problem is the existing multi-card problem of the multi-card terminal, that is, the target multi-card problem is a multi-card problem that the multi-card terminal has actually experienced, and other cell selection factors include but not limited to cell signal quality.

In an embodiment of the present disclosure, if it is determined that there are multiple neighbor base stations that can solve all the target multi-card problems according to the target capability information, then one of the neighbor base stations with the best signal quality can be selected as the target base station, so that when performing cell selection, handover to the target base station is selected.

In another embodiment, the matching degree and other cell selection factors may be assigned corresponding weight values, and after the matching degree and other cell selection factors are multiplied by the corresponding weight values respectively, the acquired sum value is determined. The neighbor base station with the maximum sum value is used as the target base station. Therefore, when performing cell selection, handover to the target base station is selected.

In practical applications, the cell selection method at least based on the target capability information corresponding to the neighbor base stations should belong to the protection scope of the present disclosure.

In the above embodiment, the multi-card terminal may perform cell selection according to the matching degree between the target capability information corresponding to at least one neighbor base station and the target multi-card problem of the multi-card terminal and/or other cell selection factors. That is to say, the multi-card terminal may perform cell selection according to at least one of the matching degree between the target capability information corresponding to at least one neighbor base station and the target multi-card problem of the multi-card terminal and other cell selection factors. While reducing the multi-card problem of multi-card terminals, considering other cell handover factors, the cell selection method is more flexible and has high availability.

In the embodiment of the present disclosure, the neighbor base station informs the base station where the multi-card terminal resides or has been accessed of the multi-card problem that it can solve.

In step 702, the base station sends the target capability information corresponding to at least one neighbor base station.

In this embodiment of the present disclosure, the base station may broadcast the target capability information corresponding to at least one neighbor base station through broadcast signaling. Or, the base station may send the target capability information corresponding to at least one neighbor base station to the multi-card terminal through unicast signaling when it is determined that the multi-card terminal is in the connected state.

In step 703, the multi-card terminal performs cell selection based on the matching degree between the target capability information and the target multi-card problem of the multi-card terminal and/or other cell selection factors. That is to say, the multi-card terminal performs cell selection based on at least one of the matching degree between the target capability information and the target multi-card problem of the multi-card terminal and other cell selection factors.

The target multi-card problem may be an existing multi-card problem of the multi-card terminal.

Of course, the multi-card terminal can also perform cell selection only according to the matching degree between the target capability information corresponding to at least one neighbor base station and the target multi-card problem of the multi-card terminal (not shown in FIG. 7).
