Wherein the capability-out indication comprises one or more of:
excess capability identification/ID;
configuration of secondary nodes;
maximum UE capability;
the range can be adjusted.
Wherein the capability-out indication further comprises:
indication information for indicating whether the capability is exceeded due to the configuration of the CHO or the CPC.
The invention is described below in conjunction with the scenario embodiments.
Example one
In this embodiment, before configuration, configuration negotiation between nodes is performed, and a network configures a CHO (MN configured) and a CPC (SN configured) for a UE, and the CHO pre-configuration example includes:
the method comprises the following steps: the MN determines to configure CHO for the UE according to the measurement result of the UE and the like;
step two: the MN informs the SN of one or more of the following information:
1) the CHO/CPC configuration indication information indicates whether CHO and/or CPC is configured, as possibly by 1 bit. And possibly the indication of CHO and CPC could be that each occupies 1bit to indicate whether configuration or not, or by different values of the same bit.
2) The total number of frequency points or specific frequency points (all frequency points or only providing frequency points different from the configuration of MN and SN) measured by UE configured by MN and/or the number of cells on each frequency point (the measurement of the number of adjacent cells is also the capability of UE; possibly also cell ID), the number of measurement identities used (one of the UE capabilities), and possibly an indication of the CHO candidate cell (e.g. increase the indication bit identity).
3) UE capability limit information such as a maximum measured frequency point number of the UE, a maximum measured cell number (same frequency, different frequency) on each frequency point, a maximum measurement identity number, and/or a maximum available capability of the SN (e.g., the measurement identity number available for the SN, the SN may configure the measured frequency point number).
4) Validity information of the configuration information, such as a Timer (after the Timer is exceeded, the configuration is disabled).
Step three: the SN receives the message of the MN;
1) if the current SN is to configure CPC for UE, the SN may initiate a measurement negotiation request with MN, and the request information includes: the number of frequency points desired to be configured (i.e. the above frequency point information) and/or the number of cells desired to be configured (and/or cell ID), the number of measurement identities, and/or the effective time of SN configuration, etc.
2) If the current SN does not intend to configure CPC for the UE, the SN will store the message from the MN and can feed back an ACK. For this case, when the SN is to configure the CPC subsequently, the SN behavior may be:
a. if the SN expects to configure more measurement cells or measure more frequency points on a certain frequency point, a measurement negotiation request is initiated to the MN, and the request information comprises the frequency point expected to be configured and/or the number of the cells (and/or cell ID) expected to be configured, the effective time of SN configuration of the measurement identity number and the like. Or b, SN will configure not to exceed UE capability based on the configuration sent by MN.
Step four: if the MN receives the measurement configuration negotiation sent by the SN, it may choose to accept or reject the negotiation, and if the MN receives the negotiation, the MN needs to adjust its produced measurement configuration accordingly. Possibly, the MN will also send an ACK message to the SN. Finally, the MN sends the configuration of the SN and the MN (updated) configuration to the UE through 1 or more RRC messages.
Similarly, if the SN first configures the CPC, it will first inform the MN of its configuration (corresponding to initiating the measurement negotiation process), and finally the MN decides to accept or reject, and possibly make corresponding adjustments to the MN-side CHO configuration.
Similarly, when the MN or SN wants to configure CPC for UE, the corresponding measurement configuration is sent to the SN or MN first, regardless of who configured first, and finally the decision right is in MN.
Example two
In this embodiment, notifying another node to perform configuration adjustment after configuration, taking the network to configure a CHO (MN configured) and a CPC (SN configured) for the UE, and configuring the CHO first as an example, includes:
the method comprises the following steps: the MN determines to configure CHO for the UE according to the measurement result of the UE and the like;
step two: MN generates corresponding RRC message and sends it to UE;
step three: the UE receives the post-feedback rrcreeconfigurationcomplete message.
Step four: the MN informs the SN of one or more of the following information:
1) the CHO/CPC configuration indication information indicates whether CHO and/or CPC is configured, as possibly by 1 bit. And possibly the indication of CHO and CPC could be that each occupies 1bit to indicate whether configuration or not, or by different values of the same bit.
2) The total number of frequency points or specific frequency points (all frequency points or only providing frequency points different from the configuration of MN and SN) measured by UE configured by MN and/or the number of cells on each frequency point (because the measurement of the number of adjacent cells is also the capability of UE; possibly also cell ID), the number of measurement identities used (one of the UE capabilities), and possibly an indication of the CHO candidate cell (e.g. increase the indication bit identity).
3) UE capability limit information such as a maximum measured frequency point number of the UE, a maximum measured cell number (same frequency, different frequency) on each frequency point, a maximum measurement identity number, and/or a maximum available capability of the SN (e.g., the measurement identity number available for the SN, the SN may configure the measured frequency point number).
4) Validity information of the configuration information, such as a Timer (after the Timer is exceeded, the configuration is disabled).
Here, step four may occur before, after, or simultaneously with step three.
Step five: after receiving the measurement configuration related to the CHO sent by the MN, the SN generates the CPC configuration based on the MN configuration and the UE capability whenever it configures the CPC (before no new CHO configuration is received by the MN and the current CHO configuration is not released (release command by the MN or release due to CHO/HO execution)), and then sends the configuration to the UE through SRB3 or SRB 1.
Step six: if the MN releases the CHO configuration proactively, the MN needs to inform the SN.
Similarly, if the SN is to configure the CPC first, the SN sends the configuration to the UE and then informs the MN of the configuration, and the subsequent MN configures the CHO and/or CPC for the UE with this as a reference, ensuring that the UE capability is not exceeded.
This embodiment can reduce the signaling interaction between nodes compared to embodiment one.
EXAMPLE III
This embodiment is UE-assisted network configuration adjustment, taking the network configuration CHO (MN-configured, SN-independent) and CPC (SN-configured, MN-independent) for the UE as examples, including:
the method comprises the following steps: the MN determines to configure CHO for the UE according to the measurement result of the UE and the like; the SN determines to configure CPC for the UE according to the measurement result;
step two: MN and SN are respectively and independently distributed to UE (MN is configured by SRB1, SN is configured by SRB3, and the other node is not informed);
step three: when the UE receives the configuration of two nodes (in sequence), the UE checks the total number of frequency points (except CHO and CPC, there may be other measurement configurations) of the two nodes, such as the total number of cells configured on different frequency points, the measurement ID number, etc., and if the UE finds that the capability of the UE is exceeded, the UE reports to the network, which may be:
1) and only reporting the nodes after configuration, and reporting the SN if the UE receives the CHO configuration of the MN first and then receives the CPC configuration of the SN. If the reporting node is SN, if SRB3 exists, the report is directly carried out through SRB3, otherwise, the report is transmitted through MN through SRB 1; if the reporting node is MN, if there is SRB1, the node is reported directly through SRB1, otherwise, the node is transmitted through SN through SRB3/split SRB. The reported information comprises the exceeding capability identification/ID, and/or the configuration condition of another node, and/or the maximum UE capability, and/or the adjustable range, etc.; in this case, only the node performing the adjustment transmits the reconfiguration message.
2) Only the MN is reported, if the SRB1 exists, the MN is directly reported through the SRB1, otherwise, the MN is transparently transmitted by the SN through the SRB3/split SRB. The reported information includes the exceeding capability identifier/ID, and/or the configuration condition of another node, and/or the maximum UE capability, and/or the adjustable range, etc. The MN may choose to make MN configuration adjustments or request SN adjustments. In this case, only the MN sends a reconfiguration message that may contain the reconfiguration content of the MN, and/or the reconfiguration content of the SN.
3) And reporting the designated node according to the network configuration. The network may specify that the MN and/or SN be reported in such a case, and the network may also configure whether the UE reports the reason for the excess capacity.
The embodiment can avoid configuration interaction between nodes to a certain extent by a mode of reporting by the UE, and may have additional requirements on the terminal.
In summary, the embodiment of the present invention can avoid the situation exceeding the capability of the UE when the CHO and the CPC are configured simultaneously, or the MN and the SN configure the CPC for the UE; meanwhile, the capability of the UE can be utilized to the maximum extent through the interaction between the auxiliary node and the measurement capability request (negotiation) and the main and auxiliary nodes, and the waste of the capability of the UE is avoided.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
