Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a cell switching control method, device, base station and storage medium. Background Art

[0002] At the current stage, the network is based on the Long Term Evolution (LTE) network (i.e. 4G network) and the New Radio (NR) network (i.e. 5G network), supplemented by the 2G network. The existing network terminals include 2G only, 2G+4G, 2G+4G+5G. Among them, the terminal will interoperate between the 4G and 5G networks when moving, including: cell reselection, cell redirection, and cell switching. However, in the network protocol version R17 stage, RedCap terminals with reduced capability (RedCap) can only access 5G cells that support RedCap. When a RedCap terminal that supports both 4G and 5G RedCap accesses the LTE network, mobility triggers switching / redirection from the LTE cell (i.e., 4G cell) to the NR cell (i.e., 5G cell). At this time, the 4G cell does not know whether the switching / redirection target 5G cell measured by the current terminal supports RedCap. When the target 5G cell does not support RedCap, the terminal will be disconnected from the network after the switching / redirection process is completed (voice service interruption, data service interruption). The terminal can only re-establish or return to the LTE network and initiate switching / redirection again. Therefore, how to ensure the system continuity and reliability of switching during terminal mobility has become a research direction for those skilled in the art. Summary of the invention

In the following description, specific details such as specific configurations and components are provided only to help fully understand the embodiments of the application.

Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0048] In the various embodiments of the present application, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0049] It should be understood that the term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0050] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0051] See also Figure 1 An embodiment of the present application provides a cell switching control method, comprising:

[0052] Step S101, when the first base station currently accessed by the target terminal meets the first preset condition or the second preset condition, obtaining the terminal capability information of the target terminal, wherein the target terminal is a terminal that needs to perform cell switching, and the terminal capability information includes: a protocol version number and whether RedCap is supported;

[0053] Step S102, performing version and capability matching on the target terminal according to the terminal capability information to obtain 5G cell matching information;

[0054] Step S103: Perform cell switching control on the target terminal according to the 5G cell matching information.

[0055] In this embodiment, when the target terminal performs cell switching, especially switching from a 4G cell (corresponding to the source base station) to a 5G cell (corresponding to the target base station), based on different execution entities, the terminal capability information of the target terminal will be obtained after it meets different preset conditions. The terminal capability information includes at least the protocol version number and whether RedCap is supported, so as to match it with the cell capability information of the 5G cell for version and capability, determine whether there is a 5G cell matching the target terminal, and control the cell switching of the target terminal according to the 5G cell matching information obtained after matching. Therefore, by matching the version and capability, it is helpful to avoid the target terminal from accessing an unmatched 5G cell, or being disconnected from the network after accessing an unmatched 5G cell.

[0056] To sum up, during the cell switching process of the target terminal, this embodiment obtains the terminal capability information of the target terminal and matches the version and capability of the 5G cell according to the terminal capability information, which is helpful to avoid the target terminal accessing an unmatched 5G cell or being disconnected from the network after accessing an unmatched 5G cell.

[0057] It should be noted that the version and capability matching described in this article refers to matching the protocol version number and whether RedCap is supported, respectively, and the target terminal is determined to match the 5G cell only when the version and capability of the target terminal match that of a 5G cell. Among them, when the protocol version number of the target terminal is compatible with that of a 5G cell, for example, the protocol version numbers of both are greater than or equal to the preset protocol version number (for example, R17), or both are less than the preset protocol version number, then the versions of the two are determined to match; when the target terminal and a 5G cell both support RedCap or neither supports RedCap, the capabilities of the two are determined to match. It should also be noted that since RedCap is related to the version, and RedCap can only be supported when the protocol version number is greater than or equal to R17, capability matching is no longer required when any protocol version number is less than R17.

[0058] It should also be noted that the terminal capability information of the target terminal is obtained, preferably by initiating a terminal capability query to the target terminal, and determining the protocol version number of the target terminal by parsing the information element (IE) field about the version based on the capability information field (Capabilityinformation) of the target terminal, and determining whether the target terminal supports RedCap by checking the information unit about RedCap.

[0059] Specifically, in the method as described above, the first preset condition is: the first base station is a 4G base station;

[0060] The second preset condition is that the first base station is a 5G base station after switching of the target terminal without version and capability matching, and the protocol version number of the first base station is lower than the preset protocol version number.

[0061] In this embodiment, an example is given based on the above preset conditions, wherein the first preset condition is: the first base station is a 4G base station, that is, the base station that performs cell switching is the source base station, and at this time, the terminal capability information of the target terminal can be obtained during the access process of the target terminal;

[0062] The second preset condition is: the first base station is a 5G base station after switching without version and capability matching for the target terminal, and the protocol version number of the first base station is lower than the preset protocol version number, that is, the base station that performs subsequent cell switching is the target base station, namely the 5G base station, that is, without version and capability matching between the target terminal and the 5G base station, the target terminal will be switched to the 5G base station first, and then the 5G base station determines whether it is necessary to obtain the terminal capability information of the target terminal according to the protocol version number of the accessed 5G cell. When its protocol version number is lower than the preset protocol version number (for example, R17), the currently accessed 5G cell cannot match the target terminal with a higher than or equal to the preset protocol version number. Therefore, it is necessary to obtain the terminal capability information of the target terminal to determine whether it is necessary to switch the target terminal to the 5G neighboring area or 4G cell again.

[0063] See also Figure 2 Specifically, in the method as described above, performing version and capability matching on the target terminal according to the terminal capability information to obtain 5G cell matching information includes:

[0064] Step S201, obtaining 5G cell measurement information uploaded by the target terminal when performing a measurement task, and determining a pre-selected 5G cell that can be switched;

[0065] Step S202, determining the cell capability information of the pre-selected 5G cell according to the pre-configured 5G cell capability information, wherein the cell capability information includes: a protocol version number and whether RedCap is supported;

[0066] Step S203: If it is determined that the cell capability information corresponding to at least one target 5G cell matches the terminal capability information, the obtained 5G cell matching information is the switching information corresponding to the target 5G cell, and the target 5G cell is any one of the pre-selected 5G cells;

[0067] Step S204: If the cell capability information corresponding to the pre-selected 5G cell does not match the terminal capability information, the obtained 5G cell matching information is that there is no target 5G cell.

[0068] In this embodiment, an example is given of the steps for obtaining 5G cell matching information when the first preset condition or the second preset condition is met. Among them, after obtaining the terminal capability information, the target terminal will execute the measurement task by issuing the measurement task about 5G, and upload the obtained 5G cell measurement information. According to the 5G cell measurement information, the pre-selected 5G cell accessible to the target terminal can be determined, and then according to the 5G cell capability information pre-configured in the first base station, the cell capability information of the pre-selected 5G cell is determined. Among them, when the first base station is a 4G base station, the RedCap capability of each 5G cell (0: RedCap is not supported, 1: RedCap is supported) and the protocol version number supporting RedCap (0: R17, 1: R18) can be marked manually in the neighboring area relationship of the 4G network or by adding the RedCap field in the self-organizing network characteristics; when the first base station is a 5G base station, the RedCap capability of each 5G cell (0: RedCap is not supported, 1: RedCap is supported) and the protocol version supporting RedCap (0: R17, 1: R18) can be marked in the 5G neighboring area relationship of the 5G base station.

[0069] Further, the cell capability information corresponding to the pre-selected 5G cell and the terminal capability information of the target terminal can be obtained according to the above, and the version and capability matching can be performed; if it is determined that the cell capability information corresponding to at least one 5G cell matches the terminal capability information, the obtained 5G cell matching information is the switching information corresponding to the matching 5G cell, which includes but is not limited to the cell ID of the 5G cell and other related information for connecting the target terminal to the cell;

[0070] If the cell capability information corresponding to the pre-selected 5G cell does not match the terminal capability information, the obtained 5G cell matching information is no target 5G cell. In other words, there is currently no 5G cell that can be accessed by the target terminal and supports the target terminal function.

[0071] It should be noted that when it is learned that the current 5G cell version is lower, by obtaining the terminal capability information of the target terminal, and matching and switching with its 5G neighboring cell based on the terminal capability information, an effective abnormal state judgment and processing mechanism is established, which can effectively ensure that the terminal does not lose network and to a certain extent ensure business continuity.

[0072] It should also be noted that this embodiment introduces a new cell IE at the base station neighboring cell relationship to carry the pre-configured cell capability information, which is beneficial to network management.

[0073] See also Figure 3Specifically, in the method as described above, when the first base station meets the first preset condition, performing version and capability matching on the target terminal according to the terminal capability information to obtain 5G cell matching information includes:

[0074] Step S301, determining a target 5G cell to be switched to according to the 5G cell measurement information uploaded by the target terminal when performing the measurement task;

[0075] Step S302, sending the terminal capability information to the target 5G cell;

[0076] Step S303, receiving the response information fed back by the target 5G cell, wherein the response information is obtained by the target cell through version and capability matching according to the terminal capability information and its own cell capability information;

[0077] Step S304: If the response information is a positive response, the obtained 5G cell matching information is the switching information corresponding to the target 5G cell;

[0078] Step S305: If the response information is a negative response, the obtained 5G cell matching information is that there is no target 5G cell.

[0079] In this embodiment, when the first base station meets the first preset condition, the version and capability matching step can also be performed by the 5G cell. In this case, it is not necessary to pre-configure the 5G cell capability information at the 4G cell. The specific steps can be: according to the 5G cell measurement information uploaded by the target terminal when performing the measurement task, and according to the measurement value sorting, the target 5G cell to be switched to is determined in sequence, wherein the step of obtaining the 5G cell measurement information is the same as above and will not be repeated here. It should be noted that when it is determined according to the 5G cell measurement information that there are multiple target 5G cells that meet the access requirements of the target terminal, the following processing is performed on each target 5G cell in sequence;

[0080] By sending the terminal capability information of the target terminal to the target 5G cell, the target 5G cell can obtain its own corresponding cell capability information and match it with the terminal capability information according to the cell capability information pre-configured in the neighboring cell relationship of the 5G base station, and feedback response information to the 4G base station based on the matching result, wherein a positive response indicates that the target 5G cell matches the target terminal, and a negative response indicates that the target 5G cell does not match the target terminal.

[0081] Then, the 5G cell matching information can be determined based on each response information. If there is a positive response, the 5G cell matching information is the switching information of the target 5G cell corresponding to the positive response; if they are all negative responses, the 5G cell matching information is that there is no target 5G cell.

[0082] It should be noted that this embodiment introduces a new cell IE at the base station neighboring cell relationship to carry the pre-configured cell capability information, which is beneficial to network management.

[0083] Specifically, in the method as described above, the cell switching control of the target terminal according to the 5G cell matching information includes at least one of the following:

[0084] If the 5G cell matching information is the switching information corresponding to the target 5G cell, switching the target terminal to the target 5G cell according to the switching information;

[0085] If the 5G cell matching information indicates that there is no target 5G cell, the target terminal is not switched, or the target terminal is switched to a 4G cell.

[0086] In this embodiment, an example is given of how to control the cell switching of the target terminal according to the 5G cell matching information. If the 5G cell matching information is the switching information corresponding to the target 5G cell, it indicates that there is currently a target 5G cell available for the target terminal to switch to, so according to the switching information corresponding to the target 5G cell, the target terminal is switched to the target 5G cell;

[0087] If the 5G cell matching information indicates that there is no target 5G cell, it indicates that there is no target 5G cell available for the target terminal to switch to, so the target terminal is not switched (preferably when the first base station is a 4G base station), or the target terminal is switched to a 4G cell (preferably when the first base station is a 5G base station, and can also be applied when the first base station is a 4G base station) to ensure the normal operation of the target terminal.

[0088] Specifically, in the method as described above, the step of switching the target terminal to a 4G cell includes:

[0089] Obtaining 4G cell measurement information uploaded by the target terminal when performing a measurement task;

[0090] Determine a target 4G cell to be switched according to the 4G cell measurement information;

[0091] Switch the target terminal to the target 4G cell.

[0092] In this embodiment, an example of how to switch to a 4G cell is given, where, when it is determined that there is no 5G cell to switch to, the 4G cell measurement information uploaded by the target terminal when executing the measurement task is obtained by sending a measurement task about 4G to the target terminal, or, when the measurement task about 5G is sent last time, the target terminal is made to synchronously execute the measurement task about 4G and obtain the 4G cell measurement information; according to the measurement value in the 4G cell measurement information, the 4G cell accessible to the target terminal is determined, and the target 4G cell to be switched is determined according to the measurement value sorting, and the target terminal is switched to the target 4G cell according to the cell ID and other information of the target 4G cell. To ensure the normal operation of the target terminal.

[0093] Further, in the above method, when the first base station satisfies the second preset condition, the method further includes:

[0094] If the target 4G cell to which the target terminal switches still belongs to the 4G base station before the switch, the 4G base station is controlled to initiate a cell switch to switch the target terminal to the 5G cell again after detecting that the target terminal service is completed or the time after the switch reaches a preset time.

[0095] In this embodiment, when the first base station satisfies the second preset condition, if the target 4G cell to which the target terminal switches still belongs to the 4G base station before the switching, that is, after the target terminal switches from a 4G base station to a 5G cell, since the 5G cell and the corresponding 5G neighboring cell do not match the target terminal, after the target terminal is switched to the original 4G base station, the 4G base station is controlled to initiate a cell switch to switch the target terminal to the 5G cell again only after detecting that the target terminal service is completed or the time after the switching reaches the preset time, which is conducive to avoiding repeated ping-pong switching.

[0096] It should be noted that its specific implementation can be: after the 4G base station pre-configures the above-mentioned detection that the time after the target terminal service is completed or the switching reaches a preset time, the delayed switching process of switching the target terminal to the 5G cell can be initiated again. When the target terminal switches back to the 4G base station from the 5G base station, the information triggering the delayed switching process is carried to trigger the delayed switching process.

[0097] Optionally, the method as described above further comprises:

[0098] When the first base station satisfies a third preset condition, first indication information is fed back to the target terminal, wherein the third preset condition is that the first base station is a 5G base station after switching of the target terminal without version and capability matching, and the protocol version number of the first base station is higher than or equal to a preset protocol version number, and the first indication information is used to indicate that the target terminal is working normally.

[0099] In this embodiment, when the first base station is a 5G base station after the target terminal has not performed version and capability matching switching, and the protocol version number of the first base station is higher than or equal to the preset protocol version number, it can match the target terminal that supports RedCap, so the target terminal can operate normally based on the first base station, and therefore the first indication information indicating that the target terminal is operating normally is fed back to the target terminal to enable it to operate normally.

[0100] It should be noted that this embodiment is mainly aimed at target terminals that support RedCap, and terminals with versions lower than the preset protocol version number are not considered in this embodiment. Specifically, in the above method, when the first base station meets the second preset condition, after obtaining the terminal capability information of the target terminal, the method further includes:

[0101] When the terminal capability information indicates that the version number of the target terminal is lower than the preset version number, second indication information is fed back to the target terminal, where the second indication information is used to indicate that the target terminal operates normally.

[0102] In this embodiment, when the first base station satisfies the second preset condition, if it is determined according to the acquired terminal capability information that the version number of the target terminal is also lower than the preset version number, it can be determined that the target terminal matches the currently accessed 5G cell. Therefore, the target terminal can operate normally in the currently accessed 5G cell. Therefore, the 5G base station feeds back the second indication information instructing the target terminal to operate normally to the target terminal so that it can operate normally.

[0103] See also Figure 4 Another embodiment of the present application further provides a cell switching control device, comprising:
