Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a receiving and configuring method, device and medium. Background Art

[0002] CHO (Conditional Hand Over) means that the network will configure multiple candidate cells for the terminal. The terminal will autonomously determine the target cell for handover based on the comparison of the channel quality of different cells and the RSRP (Reference Signal Received Power) threshold. The handover here does not require the source base station to indicate the target cell for the terminal to switch to through signaling. CHO is a mechanism to enhance the robustness of the handover process. Compared with conventional handover, conditional handover can complete the handover process more quickly, avoiding the problem that the UE (User Equipment) cannot complete the handover normally when the channel between the UE (User Equipment) and the serving cell suddenly deteriorates (especially at high frequencies or when the terminal moves at high speed).

[0003] The base station can configure the UE to trigger measurement reporting at a lower threshold. The source base station selects the target base station for handover request and confirmation based on the information reported by the user, and configures the CHO command to the UE through the RRC (Radio Resource Control) reconfiguration message. The determined CHO list is configured to the user in the CHO command, which carries a higher threshold for triggering handover, and can also carry the random access resources used by the UE in the target cell. Once the handover threshold is met, the UE initiates a random access process to the target base station.

[0004] The disadvantage of the prior art is that since the network performs conditional handover (CHO) related configuration for each UE through an RRC reconfiguration message, the signaling overhead is large. Summary of the invention

[0176] The inventors noticed during the invention process that:

[0177] In the prior art, the network performs conditional switching (CHO) related configurations for each UE through RRC reconfiguration messages, but in some specific situations, the overhead can be reduced. For example, in scenarios such as high-speed rail, UEs in a carriage are usually switched at the same time. Since the high-speed rail line is relatively fixed, the candidate target cells for switching are usually the same. Therefore, for this scenario, the relevant configurations of CHO can be performed in a grouping manner, and the parameters shared by the UEs in the group can be sent down in a public manner, which can effectively reduce the signaling overhead.

[0178] Based on this, an embodiment of the present invention provides a conditional switching configuration scheme and a switching scheme.

[0179] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0180] In the description process, the implementation of the terminal and the network side will be described respectively, and then an example of the coordinated implementation of the two will be given to better understand the implementation of the solution given in the embodiment of the present invention. This description does not mean that the two must be implemented in coordination or must be implemented separately. In fact, when the terminal and the network side are implemented separately, they also solve the problems on their own side, and when the two are used in combination, better technical effects will be obtained.

[0181] Figure 1 A flow chart of a configuration method for a network side is provided, as shown in the figure, which may include:

[0182] Step 101: The network side sends first information to the group of terminals, wherein the first information includes one or a combination of the following information:

[0183] Measurement reporting trigger condition information, switching execution condition information, candidate cell information, cell information removed from candidate cells, and random access information.

[0184] During implementation, the network side sends at least two first information, which are applied to different terminals and / or terminal groups.

[0185] Specifically, multiple first information may be configured to correspond to different terminals and / or terminal groups. Furthermore, a corresponding / mapping relationship between the first information and the terminals and / or terminal groups may be given.

[0186] In implementation, the mapping / correspondence between the first information and the terminal and / or the terminal group is specified by the standard or sent by the network side.

[0187] During implementation, the network side determines the mapping / correspondence between the terminal grouping and / or the first information and the terminal and / or the terminal group according to the uplink channel quality and / or the uplink Doppler frequency of the terminal.

[0188] Figure 2 A schematic diagram of a receiving method on the terminal side is provided, as shown in the figure, which may include:

[0189] Step 201: The terminal receives first information, wherein the first information includes one of the following information or a combination thereof: measurement reporting trigger condition information, switching execution condition information, candidate cell information, cell information of removed candidate cells, and random access information.

[0190] Furthermore, it may also include:

[0191] Step 202: The terminal switches according to the first information.

[0192] This is because the first information can be used in a conditional switching scenario as well as in other switching scenarios, and the following mainly uses the switching scenario as an example for explanation.

[0193] In implementation, the first information is applied to one terminal or at least two terminals.

[0194] The following is an explanation, which will be mainly divided into three parts, namely: the content of the first information of the group configuration, the switching or conditional switching command of the group configuration issued by the network, and the terminal behavior. However, it should be noted that the three parts are only for the convenience of explanation, and do not involve the explanation of the scheme and technical features. The scheme will also be divided into three parts. The following is a specific description of the scheme.

[0195] 1. Content of the first information of the group configuration.

[0196] In implementation, the first information may include one or a combination of the following information:

[0197] Measurement reporting trigger condition information, switching execution condition information, candidate cell information, cell information removed from candidate cells, and random access information.

[0198] Specifically, the network sends first information, where the first information may be applied to a group of UEs, and the first information includes at least one of the following:

[0199] 1. Measurement report triggering condition information. Specifically, the measurement report triggering condition here refers to the triggering condition for reporting the measurement result on the network side, including at least one of the following: measurement quantity, measurement report triggering event. Multiple measurement report triggering conditions can be configured. For example, different measurement report triggering conditions can be configured for conditional switching scenarios and normal switching (non-conditional switching) scenarios;

[0200] 2. The switching execution condition information may include a first channel quality threshold and a second channel quality threshold (eg RSRP, RSRQ (reference signal received quality), SINR (signal to interference plus noise ratio)).

[0201] The first channel quality threshold is used to determine whether to enable conditional switching. Specifically, when the channel quality of the serving cell is lower than the first channel quality threshold, the terminal enables conditional switching related operations, such as enabling measurement of switching candidate cells configured for multiple networks; when the channel quality of the serving cell is higher than the first channel quality threshold, the terminal does not need to enable conditional switching related operations.

[0202] When the channel quality of the first cell is lower than and / or equal to the first channel quality threshold, the conditional switching is initiated. The first cell may be a serving cell.

[0203] When the channel quality of the second cell is higher than and / or equal to the second channel quality threshold, the second cell may be used as a target cell or a candidate cell for switching.

[0204] The second channel quality threshold is used to determine the target cell. The second channel quality threshold is used by the terminal to autonomously determine the target cell for handover. Specifically, among multiple candidate cells, the cell whose channel quality meets the second channel quality threshold becomes the target cell for handover.

[0205] Alternatively, multiple candidate cells may be configured with the same second channel quality threshold, or different candidate cells may be configured with different second channel quality thresholds. Regarding the latter, since the second channel quality thresholds of different candidate cells are different, the order of target cells in multiple consecutive conditional switches can be determined.

[0206] That is, the switching execution condition information includes: a first channel quality threshold and / or a second channel quality threshold, wherein the first channel quality threshold is used to determine whether to start the conditional switching, and the second channel quality threshold is used to determine the target cell.

[0207] 3. Candidate cell information: Specifically, the candidate cell information here refers to the candidate cell information of the target cell to be switched by the terminal, such as the cell identifier PCI (Physical Cell Identifier), including multiple candidate cell information for conditional switching, such as PCI.

[0208] Alternatively, the priority of multiple candidate cells for conditional handover of the terminal may be indicated, for example, the priority may be implicitly expressed by the order of the multiple candidate cells in the signaling;

[0209] 4. Remove the cell information of the candidate cell;

[0210] 5. Random access information. Specifically, the random access information here can be contention random access information or non-contention random access information. For example, it includes at least one of the following: subcarrier spacing, random access preamble, time domain information, frequency domain information, terminal identification, and terminal group identification;

[0211] Furthermore, multiple random access information may be configured and applied to different terminals and / or terminal groups. Specifically, the correspondence / mapping relationship between the random access information and the terminals and / or terminal groups will be given.

[0212] In implementation, if the RRC reconfiguration message includes CFRA, the terminal performs non-contention random access based on the CFRA resources in the RRC reconfiguration message;

[0213] If the RRC reconfiguration message does not include CFRA, the terminal performs random access based on the random access information in the first information.

[0214] Specifically, if the first information of the group configuration includes random access information, then the random access information is applied to all UEs in the UE group. The UEs in the group adopt contention random access;

[0215] If the RRC reconfiguration message includes CFRA (Contention Free Random Access), then regardless of whether there is random access information in the first information of the group configuration, the terminal performs non-contention random access based on the CFRA resources in the RRC reconfiguration message;

[0216] If the RRC reconfiguration message does not include CFRA, the terminal uses the random access information in the first information of the group configuration to perform random access.

[0217] In implementation, multiple group configuration first information may be configured and applied to different group UEs. If multiple group first information is configured, the group identifier may be configured in the group configuration conditional command.

[0218] 2. The network sends the first information of grouping configuration.

[0219] In implementation, the terminal receives the first information sent by the network side through one of the following messages or a combination thereof:

[0220] Broadcast message, multicast message, groupcast message.

[0221] In a specific implementation, the terminal receives the first information sent by the network side in one of the following ways or a combination thereof:

[0222] Broadcast message, multicast message, groupcast message.

[0223] During implementation, the network side receives a first identifier from the group of terminals, where the first identifier indicates whether to send the first information.

[0224] Specifically, the first identifier is used to notify the terminal network side whether the first information has been sent, that is, whether measurement reporting trigger condition information and / or condition execution condition information and / or candidate cell information and / or cell information for removing candidate cells and / or random access information has been sent.

[0225] The first identifier may be sent via a broadcast message, a multicast message, a groupcast message, or an RRC reconfiguration message.

[0226] During implementation, the network side sends the second information to the group of terminals, where the second information is information related to whether the terminals receive or apply the first information.

[0227] In an implementation, the second information includes one or a combination of the following information:

[0228] Terminal identification, specifically, the terminal identification can be identified by RNTI (Radio Network Temporary Identity);

[0229] A terminal group identifier. Specifically, the terminal group identifier may be an identifier of a terminal group consisting of at least one terminal, and the first information may be applied to all terminals in the terminal group;

[0230] Terminal identification within the terminal group;

[0231] The identifier of the terminal group to which the terminal belongs;

[0232] The second indication information is used to notify the terminal whether to receive or apply the first information. Specifically, the second indication information can indicate whether a certain terminal receives the first information, and can also indicate whether a certain terminal group receives the first information.

[0233] For example, the second indication information may be indicated by one bit, for example, when the bit is set to 1, it indicates that the terminal needs to receive the first information.

[0234] For another example, if the second indication information is configured as true, it indicates that the terminal needs to receive the first information.

[0235] Multiple second indication information may be configured and applied to multiple terminals or multiple terminal groups;

[0236] The first speed threshold is related to whether the terminal receives or applies the first information. Specifically, the terminal can compare its own moving speed with the first speed threshold to determine whether to use the first information. Specifically, if the moving speed of the terminal is higher than or equal to the first speed threshold, the terminal can use the first information; if the moving speed of the terminal is lower than the speed threshold, the terminal uses the conditional switching configuration in the RRC reconfiguration message.

[0237] In implementation, the first identifier and / or the second information is delivered via one of the following messages or a combination thereof:

[0238] Broadcast message, multicast message, groupcast message, RRC reconfiguration message.

[0239] In implementation, the terminal receives the first information when one of the following conditions or a combination thereof is met:

[0240] When the first identifier indicates that the first information has been sent, receiving the first information;

[0241] When the second information instructs the terminal to receive the first information, receiving the first information;

[0242] When the speed meets the first speed threshold, first information is received.

[0243] Specifically, obtaining the first information carried in the sent broadcast message, multicast message, or groupcast message;

[0244] When it is determined through an indication in a broadcast message or an RRC message that the first information needs to be received in a broadcast message, a multicast message, or a groupcast message, obtaining the configured first information carried in the sent broadcast message, the multicast message, or the multicast message;

[0245] When it is determined through the terminal list sent by the RNTI that the first information needs to be received in the broadcast message, multicast message, or groupcast message, the first information of the configuration carried in the sent broadcast message, multicast message, or groupcast message is obtained;

[0246] The first information of the configuration carried in the broadcast message, multicast message, or groupcast message sent down is obtained, and the speed threshold sent down through the broadcast message is received, and whether to execute the first information is determined according to the speed threshold.

[0247] The details are described below.

[0248] Method 1: Acquire the first information carried in the sent broadcast message, multicast message, or groupcast message.

[0249] First information is added to a broadcast, multicast, or groupcast message.

[0250] The terminal may periodically read broadcast, multicast, or groupcast messages to obtain the first information.

[0251] The implementation also includes:

[0252] The terminal performs switching based on the first information and the switching related information in the RRC reconfiguration message.

[0253] During implementation, one or a combination of the following steps is also included:

[0254] The terminal receives the first information and the RRC reconfiguration message including the switching information, and the terminal performs switching based on the RRC reconfiguration message;

[0255] The terminal receives the first information and the RRC reconfiguration message including the switching information, and for the parameters configured in both the first information and the RRC reconfiguration message, the terminal adopts the configuration based on the RRC reconfiguration message for the parameters;

[0256] The terminal receives the first information and the RRC reconfiguration message including the switching information, and for a parameter not configured in the RRC reconfiguration message, the terminal adopts the configuration based on the first information for the parameter;

[0257] The terminal receives the first information and the RRC reconfiguration message including the switching information, and for the parameters not configured in the first information, the terminal adopts the configuration based on the RRC reconfiguration message for the parameters.

[0258] Specifically, if the RRC reconfiguration message is configured with information related to switching or conditional switching, the terminal first adopts the switching or conditional switching configuration in the RRC reconfiguration message. If the RRC reconfiguration message does not include switching or conditional switching configuration, the terminal adopts the first information configured or grouped in the broadcast, multicast, or groupcast message. If the RRC reconfiguration message is configured with switching or conditional switching, but the switching or conditional switching information lacks configuration for some parameters, then for the missing parameter configuration in the RRC reconfiguration message, the terminal adopts the first information configured or grouped in the broadcast, multicast, or groupcast message.

[0259] Method 2: When it is determined through an indication in a broadcast message or an RRC message that the first information needs to be received in a broadcast message, a multicast message, or a groupcast message, the configured first information carried in the sent broadcast message, the multicast message, or the groupcast message is obtained.

[0260] Adding first information of group configuration in a broadcast, multicast, or groupcast message. Notifying the terminal through an indication mark that the first information has been sent in the broadcast, multicast, or groupcast message. The indication mark is used to notify the terminal to receive the relevant first information in the broadcast, multicast, or groupcast.

[0261] Specifically, the indicator can indicate that the terminal only receives the first information of broadcast, multicast, or groupcast; the indicator can also indicate that the terminal receives the configuration of some conditional switching parameters in broadcast, multicast, or groupcast. The indicator notification can be sent in the following ways:

[0262] 1) Issued via broadcast;

[0263] 2) Sending through RRC message, for example, adding an indication flag in the RRC reconfiguration message.

[0264] If the terminal receives the indication identifier, the terminal performs conditional switching based on the first information in the broadcast, multicast, or groupcast message.

[0265] If the terminal receives a network notification that it can obtain the first information in the broadcast, multicast, or multicast, but the terminal also receives a switching or conditional switching information based on the RRC reconfiguration message, for some parameters, if the switching or conditional switching information in the RRC reconfiguration message and the first information of the broadcast, multicast, or multicast are configured, then the terminal uses the relevant configuration of the first information in the reconfiguration message for these parameters; for some parameters, they are only configured in the first information of the broadcast, multicast, or multicast, then the terminal uses the relevant configuration in the first information of the broadcast, multicast, or multicast for these parameters.

[0266] Method three: when the terminal list sent by RNTI determines that the first information needs to be received in the broadcast message, multicast message, or groupcast message, the configured first information carried in the sent broadcast message, multicast message, or groupcast message is obtained.

[0267] On the basis of the first and second methods, a UE list (user equipment list) may be sent through broadcasting, and the UE list may indicate the UE through an RNTI (Radio Network Temporary Identifier).

[0268] Only the UEs in the UE list need to receive the first information configured by broadcast, multicast, or groupcast.

[0269] The UE list may also be indicated in groups, and UEs in different groups may use different first information.

[0270] Method 4: obtaining the first information of the configuration carried in the broadcast message, multicast message, or groupcast message sent, and receiving the speed threshold sent through the broadcast message, and determining whether to execute the first information according to the speed threshold.

[0271] On the basis of the first, second and third methods, a speed threshold may be sent down by broadcasting. The UE compares its own moving speed with the speed threshold to determine whether to use the first information configured by broadcasting, multicasting or groupcasting.

[0272] Specifically, if the terminal's moving speed is higher than or equal to the speed threshold, the terminal can use the first information configured by broadcast, multicast, or groupcast; if the terminal's moving speed is lower than the speed threshold, the terminal uses the switching or conditional switching information in the RRC reconfiguration message.

[0273] 3. Terminal behavior.

[0274] Accordingly, for the implementation on the terminal side, in addition to the corresponding actions on the network side, the following can also be performed:

[0275] The implementation also includes:

[0276] If the RRC reconfiguration message includes CFRA, the terminal performs non-contention random access based on the CFRA resources in the RRC reconfiguration message;

[0277] If the RRC reconfiguration message does not include CFRA, the terminal performs random access based on the random access information in the first information.

[0278] During implementation, one or a combination of the following steps is also included:

[0279] The terminal receives the first information and the RRC reconfiguration message including the switching information, and the terminal performs switching based on the RRC reconfiguration message;

[0280] The terminal receives the first information and the RRC reconfiguration message including the switching information, and for the parameters configured in both the first information and the RRC reconfiguration message, the terminal adopts the configuration based on the RRC reconfiguration message for the parameters;

[0281] The terminal receives the first information and the RRC reconfiguration message including the switching information, and for a parameter not configured in the RRC reconfiguration message, the terminal adopts the configuration based on the first information for the parameter;

[0282] The terminal receives the first information and the RRC reconfiguration message including the switching information, and for the parameters not configured in the first information, the terminal adopts the configuration based on the RRC reconfiguration message for the parameters.

[0283] The terminal obtains the first information related configuration in the broadcast, multicast, or groupcast message. There are several specific ways:

[0284] Method 1: The terminal obtains the complete first information in a broadcast, multicast, or groupcast message.

[0285] If the terminal obtains a signaling notification that the complete first information can be obtained in a broadcast, multicast, or groupcast message, then the terminal obtains the first information in the broadcast, multicast, or groupcast message;

[0286] If the terminal obtains a signaling notification that the complete first information can be obtained in a broadcast, multicast, or groupcast message, and the terminal also receives the switching or conditional switching information configured by the RRC reconfiguration message, then the terminal adopts the switching or conditional switching information configured by the RRC reconfiguration message;

[0287] In a scenario where the network does not notify the terminal through signaling whether the terminal can obtain the complete first information in the broadcast, multicast, or multicast message, if the terminal does not receive the switching or conditional switching information configured by the RRC reconfiguration message, but the terminal receives the first information in the broadcast, multicast, or multicast message, then the terminal uses the first information in the broadcast, multicast, or multicast message.

[0288] Method 2: The terminal obtains part of the first information in a broadcast, multicast, or groupcast message, and obtains part of the switching or conditional switching information in an RRC reconfiguration message.

[0289] If the terminal obtains a signaling notification that part of the first information can be obtained in a broadcast, multicast, or multicast message, the terminal adopts the first information in the broadcast, multicast, or multicast message for the corresponding switching or conditional switching parameters;

[0290] If the terminal obtains a signaling notification that part of the first information can be obtained in a broadcast, multicast, or groupcast message, for some parameters, there is a scenario where both the first information in the broadcast, multicast, or groupcast message and the RRC reconfiguration message are configured, in which case the terminal adopts the configuration of the RRC reconfiguration message. For parameters that are only configured in a broadcast, multicast, or groupcast message, the terminal adopts the broadcast first information.

[0291] In a scenario where the network does not notify the terminal through signaling whether it can obtain part of the first information in a broadcast, multicast, or groupcast message, the broadcast, multicast, or groupcast message and the RRC reconfiguration message both configure the switching or conditional switching. If the parameters configured by the two do not overlap, the terminal obtains the complete switching or conditional switching configuration based on the broadcast, multicast, or groupcast message and the RRC reconfiguration message. If the parameters configured by the two overlap, for the overlapping part, the terminal adopts the switching or conditional switching configuration in the RRC reconfiguration message, and for the non-overlapping configured parameters, the terminal obtains the relevant switching or conditional switching parameters based on the respective switching or conditional switching configurations in the broadcast, multicast, or groupcast message and the RRC reconfiguration message.

[0292] The following is an explanation through examples.

[0293] Embodiment 1:

[0294] In this example, a new SIB (System Information Block) message is added to the broadcast message, and the SIB message carries the first information. The terminal periodically reads the SIB message to obtain the first information.

[0295] If the RRC reconfiguration message is configured with switching or conditional switching information, the terminal first adopts the switching or conditional switching configuration in the RRC reconfiguration message. If the RRC reconfiguration message does not have switching or conditional switching configuration, the terminal adopts the first information of the group configuration in the broadcast or multicast message. If the RRC reconfiguration message is configured with switching or conditional switching information, but the switching or conditional switching information lacks configuration of some parameters, then for the missing parameter configuration in the RRC reconfiguration message, the terminal adopts the first information of the group configuration in the broadcast or multicast message.

[0296] Alternatively, a UE list may be sent in a broadcast message, and the UEs in the UE list may determine the first information to be adopted based on the above solution.

[0297] Alternatively, a speed threshold may be sent in a broadcast message. If the moving speed of the terminal is higher than or equal to the speed threshold, the terminal may determine the first information to be adopted based on the above scheme. If the moving speed of the terminal is lower than the speed threshold, the terminal may adopt the switching or conditional switching configuration in the RRC reconfiguration message, or may not adopt the first information sent in the broadcast, multicast, or groupcast message.

[0298] Embodiment 2:

[0299] In this example, the first information is added to the broadcast message, and the first information is carried by an existing SIB message. The terminal periodically reads the SIB message to obtain the first information.

[0300] If the RRC reconfiguration message is configured with switching or conditional switching information, the terminal first adopts the switching or conditional switching configuration in the RRC reconfiguration message. If the RRC reconfiguration message does not have switching or conditional switching configuration, the terminal adopts the first information of the group configuration in the broadcast or multicast message. If the RRC reconfiguration message is configured with switching or conditional switching information, but the switching or conditional switching information lacks configuration of some parameters, then for the missing parameter configuration in the RRC reconfiguration message, the terminal adopts the first information of the group configuration in the broadcast or multicast message.

[0301] Alternatively, a UE list may be sent in a broadcast message, and the UEs in the UE list may determine the first information to be adopted based on the above solution.

[0302] Alternatively, a speed threshold may be sent in a broadcast message. If the moving speed of the terminal is higher than or equal to the speed threshold, the terminal may determine the first information to be adopted based on the above scheme. If the moving speed of the terminal is lower than the speed threshold, the terminal may adopt the switching or conditional switching configuration in the RRC reconfiguration message, or may not adopt the first information sent in the broadcast, multicast, or groupcast message.

[0303] Embodiment 3:

[0304] In this example, a new SIB message is added to the broadcast message, and the SIB message carries the first information. The network sends an indication identifier to notify the terminal that the first information can be obtained in the broadcast message. The terminal receives the indication identifier and learns that the first information can be obtained in the broadcast message, and the terminal reads the corresponding broadcast message to obtain the first information.

[0305] Alternatively, a UE list may be sent in a broadcast message, and the UEs in the UE list may determine the first information to be adopted based on the above solution.

[0306] Alternatively, a speed threshold may be sent in a broadcast message. If the moving speed of the terminal is higher than or equal to the speed threshold, the terminal may determine the first information to be adopted based on the above scheme. If the moving speed of the terminal is lower than the speed threshold, the terminal may adopt the switching or conditional switching configuration in the RRC reconfiguration message, or may not adopt the first information sent in the broadcast, multicast, or groupcast message.

[0307] Embodiment 4:

[0308] In this example, the first information is added to the broadcast message, and the first information is carried by the existing SIB message. The network sends an indication identifier to notify the terminal that the first information can be obtained in the broadcast message. The terminal receives the indication identifier and learns that the first information can be obtained in the broadcast message, and the terminal reads the corresponding broadcast message to obtain the first information.

[0309] Alternatively, a UE list may be sent in a broadcast message, and the UEs in the UE list may determine the first information to be adopted based on the above solution.

[0310] Alternatively, a speed threshold may be sent in a broadcast message. If the moving speed of the terminal is higher than or equal to the speed threshold, the terminal may determine the first information to be adopted based on the above scheme. If the moving speed of the terminal is lower than the speed threshold, the terminal may adopt the switching or conditional switching configuration in the RRC reconfiguration message, or may not adopt the first information sent in the broadcast, multicast, or groupcast message.

[0423] A computer-readable storage medium is provided in an embodiment of the present invention, characterized in that the computer-readable storage medium stores a computer program for executing the switching or conditional switching CHO configuration method and / or the switching or conditional switching CHO configuration receiving method as claimed in the claims.

[0424] For specific implementation, please refer to the implementation of the switching or conditional switching CHO configuration method and / or the switching conditional switching CHO configuration receiving method.

[0425] In summary, in the technical solution provided in the embodiment of the present invention, the configuration information of conditional switching is delivered in a grouped manner, and the configuration information can be applied to multiple UEs.

[0426] The first information of the group can be sent through broadcast or multicast, or groupcast.

[0427] The terminal may be notified of whether the first information of the packet exists through network signaling. The signaling notification may be broadcast or may be an RRC message.

[0428] The terminal may obtain the switching or conditional switching configuration based on broadcast alone; the terminal may also obtain the switching or conditional switching configuration based on broadcast and RRC reconfiguration message jointly.

[0429] In the prior art, the network performs conditional switching configuration for each UE through RRC reconfiguration messages. In scenarios such as high-speed rail, UEs in a carriage are usually switched at the same time. Since the high-speed rail line is relatively fixed, the candidate target cells for switching are usually the same. Therefore, for such scenarios, switching or conditional switching configuration can be performed in a grouping manner, and the parameters shared by the UEs in the group can be sent in a public manner, which can effectively reduce signaling overhead.
