[0334] indication information for indicating whether the capability exceeds due to configuration of CHO or CPC.

[0335] The present application will be described below in combination with a scenario embodiment.

[0336] Embodiment one

[0337] The embodiment performs configuration negotiation between nodes before configuration, and the network configures CHO (configured by MN) and CPC (configured by SN) for UE, and CHO is configured first, including:

[0338] Step 1: MN decides to configure CHO for UE according to the measurement result of UE, etc.

[0339] Step 2: MN informs SN of one or more of the following information:

[0340] 1) CHO / CPC configuration indication information, such as indicating whether CHO and / or CPC is configured by 1 bit. And possibly, the indication of CHO and CPC can each occupy 1 bit to indicate whether to configure or not, or be indicated by different values of the same bit.

[0341] 2) The total number of frequency points of UE measurement configured by MN, or specific frequency points (all frequency points or only provide frequency points different from the configuration of MN and SN) and / or the number of cells on each frequency point (the number of measurement neighboring cells is also a UE capability; possibly, there is also a cell ID), the number of measurement identities used (one of UE capabilities), and possibly, the CHO candidate cell is indicated (such as adding an indication bit).

[0342] 3) UE capability limit information such as the maximum number of measurement frequency points, the maximum number of measurement cells on each frequency point (intra-frequency, inter-frequency), the maximum number of measurement identities, and / or the maximum capability available to SN (such as the number of measurement identities available to SN, the number of measurement frequency points that can be configured by SN).

[0343] 4) Validity period information of the above configuration information, such as a timer (the above configuration is invalid after the timer is exceeded).

[0344] Step 3: SN receives the message from MN;

[0345] 1) If the current SN intends to configure CPC for UE, the SN can initiate a measurement negotiation request to MN, and the request information includes: the number of expected configured frequency points (i.e. the frequency point information above) and / or the number of expected configured cells (and / or cell ID), the number of measurement identities, and / or the validity time of SN configuration, etc.

[0346] 2) If the current SN does not intend to configure CPC for UE, the SN will store the message sent by MN, and can feedback ACK. For this case, when the SN subsequently configures CPC, the SN behavior can be:

[0347] a. If SN expects to configure more measurement cells or more frequency points, it initiates measurement configuration negotiation to MN, and the information contains the expected frequency points and / or the expected number of cells (and / or cell ID), the number of measurement identities, the valid time of SN configuration, etc. Or b. SN will base on the configuration sent by MN to make the configuration not exceeding the UE capability.

[0348] Step four: If MN receives the measurement configuration negotiation sent by SN, it can choose to receive or reject, if it receives, MN needs to adjust the measurement configuration accordingly. Possibly, MN will also send an ACK message to SN. Finally, MN sends the SN configuration and the (updated) configuration of MN to UE through one or more RRC messages.

[0349] Similarly, if SN wants to configure CPC first, it will also inform MN of its configuration (equivalent to initiating the measurement negotiation process), and finally MN decides to receive or reject, and possibly adjusts the CHO configuration on the MN side accordingly.

[0350] Similarly, when MN or SN wants to configure CPC for UE, it also needs to inform SN or MN of the corresponding measurement configuration first, regardless of who configures first, and the final decision is made by MN.

[0351] Embodiment two

[0352] This embodiment informs the other node to adjust the configuration after the configuration, such as configuring CHO (MN configuration) and CPC (SN configuration) for UE by the network, taking the CHO configuration as an example, including:

[0353] Step one: MN decides to configure CHO for UE according to the measurement results of UE, etc.

[0354] Step two: MN generates the corresponding RRC message and sends it to UE.

[0355] Step three: UE feeds back the RRCReconfigurationcomplete message after receiving it.

[0356] Step four: MN informs SN of one or more of the following information:

[0357] 1) CHO / CPC configuration indication information, such as possibly indicating whether CHO and / or CPC is configured through 1 bit. And possibly, the indication of CHO and CPC can each occupy 1 bit to indicate whether it is configured, or it can be indicated through different values of the same bit.

[0358] 2) Total number of frequencies or specific frequencies (all frequencies or only provide different frequencies from MN and SN configuration) and / or number of cells on each frequency (since the number of measured neighbor cells is also a UE capability; possibly, also the cell ID), number of measurement identities used (one of UE capabilities), and possibly, indication of CHO candidate cells (such as adding an indication bit).

[0359] 3) UE capability limitation information such as maximum number of measured frequencies, maximum number of measured cells on each frequency (intra-frequency, inter-frequency), maximum number of measurement identities, and / or maximum capability available for SN (such as number of measurement identities available for SN, number of measurement frequencies configurable for SN).

[0360] 4) Validity information of the above configuration information such as a timer (after which the above configuration is invalid).

[0361] Here, step four can occur before, after or simultaneously with step three.

[0362] Step five: When the SN receives the CHO-related measurement configuration from the MN, it will generate the CPC configuration based on the MN's configuration and UE capability, and then send the configuration to the UE through SRB3 or SRB1, regardless of when the SN configures the CPC (before receiving the new CHO configuration from the MN and before the current CHO configuration is released (MN sends a release instruction or CHO / HO execution causes release)).

[0363] Step six: If the MN actively releases the CHO configuration, the MN needs to inform the SN.

[0364] Similarly, if the SN wants to configure the CPC first, it will send the configuration to the UE, and then tell the MN about its configuration, and the MN will configure CHO and / or CPC for the UE based on this, ensuring that the UE's capabilities are not exceeded.

[0365] This embodiment can reduce inter-node signaling interaction compared to embodiment one.

[0366] Embodiment three

[0367] This embodiment is a UE-assisted network configuration adjustment. Taking the case of the network configuring CHO (configured by the MN, independent of the SN) and CPC (configured by the SN, independent of the MN) for the UE as an example, it includes:

[0368] Step one: The MN decides to configure CHO for the UE based on the UE's measurement results, etc.; the SN decides to configure CPC for the UE based on the measurement results;

[0369] Step two: MN and SN each independently issue configuration to UE (MN through SRB1, SN through SRB3 configuration, and does not inform another node);

[0370] Step three: When UE receives the configuration of two nodes (with precedence), UE will check the total configuration of two nodes (in addition to CHO and CPC, there can be other measurement configuration) such as total frequency point number, total cell number on different frequency points, measurement ID number, etc., if it is found that it exceeds its UE capability, UE reports to the network, possible ways are:

[0371] 1) Only report the node after configuration, such as UE first receives CHO configuration of MN, and then receives CPC configuration of SN, then report SN. If the reporting node is SN, if there is SRB3, report directly through SRB3, otherwise, report through SRB1 by MN transparent transmission; if the reporting node is MN, if there is SRB1, report directly through SRB1, otherwise, report through SRB3 / split SRB by SN transparent transmission. The reporting information contains the exceeding capability identification / ID, and / or the configuration of another node, and / or the maximum UE capability, and / or the adjustable range, etc.; in this case, only the node for adjustment sends the reconfiguration message.

[0372] 2) Only report MN, if there is SRB1, report directly through SRB1, otherwise, report through SRB3 / split SRB by SN transparent transmission. The reporting information contains the exceeding capability identification / ID, and / or the configuration of another node, and / or the maximum UE capability, and / or the adjustable range, etc. MN can choose to adjust the MN configuration or request SN adjustment. In this case, only MN sends the reconfiguration message, which may contain the reconfiguration content of MN, and / or the reconfiguration content of SN.

[0373] 3) According to network configuration, report the specified node. The network can specify to report MN and / or SN in this case, and the network can also configure whether the UE reports the reason for exceeding the capability.

[0374] The embodiment can avoid the interaction between nodes to some extent through the reporting mode of UE, which may have additional requirements for the terminal.

[0375] In summary, the embodiment of the application can avoid the occurrence of exceeding UE capability in the case of CHO and CPC configuration, or MN and SN both configuring CPC for UE; at the same time, through the measurement capability request (negotiation) of the secondary node and the interaction between the primary and secondary nodes, the UE capability can also be maximized, and the waste of UE capability can be avoided.

[0376] The above is only a preferred embodiment of the application, and is not used to limit the protection scope of the application.
