Description

Dual-connection configuration method, device, base station and terminal
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a dual connectivity configuration method, an apparatus, a base station, and a terminal.
Background
In order to recover Carrier Aggregation (CA) configuration quickly, an idle mode related measurement and reporting mechanism has been introduced in a Long Term Evolution (Long Term Evolution, LTE) system. When a User Equipment (UE) supports an IDLE state measurement capability of a CA and an IDLE state measurement configuration parameter configured by a network is stored in an IDLE state, the IDLE state measurement may be performed, and when a relevant measurement result is stored, the measurement result is carried in a process that the UE enters a connected state. After receiving the measurement result, the network side can directly configure the activated CA cell for the UE.
In the dual connectivity architecture, there may be a Master Node (MN for short) and one or more Secondary nodes (SN for short), where the MN and the SN are both base station nodes and may be used in LTE/e-LTE/New air interface (NR) technologies.
In the prior art, after establishing/reestablishing/recovering a connection state through a (Radio Resource Control, RRC for short) connection, a UE is kept in a single connection state, then a network side issues an RRC reconfiguration message to request the UE to perform Radio Resource Management (RRM) measurement, and finally the network side performs subsequent processes such as SN addition and the like according to a measurement result reported by the UE to instruct the UE to enter/recover dual connection. This procedure will take a long time, which results in that it is not possible to quickly enter the dual connection state for large data volume/high reliability data transceiving after establishing/reestablishing/recovering the RRC connection.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention provides a dual connectivity configuration method, applied to a first network node, including:
step 11, receiving a measurement result of radio resource management RRM, where the measurement result is obtained by measurement in an idle state/inactive state according to a measurement configuration parameter, where the measurement configuration parameter is related to a first network node and a second network node.
In this embodiment, the first network node may be a primary node MN of a base station, and the second network node may be a secondary node SN of the base station. Aiming at the RRC establishment/recovery/reconstruction process, the UE carries out RRM measurement according to measurement configuration parameters in the IDLE state IDLE/INACTIVE state INACTIVE and connection reconstruction processes, and reports RRM measurement results to the first network node, wherein the measurement configuration parameters are related to the first network node and the second network node, and the RRM measurement results comprise measurement results related to the first network node and measurement results related to the second network node.
In the RRC reestablishment process, between the failure/handover of the radio link between the terminal and the first network node and the process of sending the reestablishment request to the first network node by the terminal, the terminal performs measurement according to the measurement configuration parameter, and therefore, it is considered that the UE performs measurement in the RRC reestablishment process in an IDLE state.
Wherein the measurement configuration parameters may include at least one of:
measuring frequency point list information, such as carrier frequency points, and/or measuring frequency point numbers and the like;
cell list information, such as Physical Cell Identifier (PCI);
measurement period duration information, i.e. the measurement collection interval for the measurement when the UE enters IDLE/INACTIVE state;
measuring bandwidth;
the measurement Area may be a cell list, a Tracking Area (TA) list, a Public Land Mobile Network (PLMN) list, or the like;
the reported measurement settings may include Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), etc.;
a measurement evaluation threshold value (a threshold value which can be any one of RSRP, RSRQ, and SINR);
the terminal measures the subcarrier spacing of the wideband Part (BWP for short).
And step 12, configuring double connection for the terminal according to the measurement result.
And after receiving the RRM measurement result sent by the UE, the first network node sends the measurement result related to the second network node, and initiates an addition/modification process of the second network node, wherein the measurement results can be used for quick recovery of dual connection of the UE.
Specifically, in the RRC establishment/recovery process, the measurement configuration parameter according to which the UE performs the RRM measurement is issued by the first network node, and in the RRC reestablishment process, the measurement configuration parameter according to which the UE performs the RRM measurement is measurement configuration in a connected state before the radio connection failure. It should be noted that the first network node that sends the measurement configuration parameter to the terminal and the first network node after RRC connection establishment/recovery/reestablishment may be the same network node or different network nodes; the second network node related to the measurement configuration parameter and the second network node after RRC connection establishment/recovery/reestablishment may be the same network node or different network nodes.
Specifically, step 11 may be implemented by, but is not limited to, the following:
in a first mode, in a radio resource control RRC establishment/recovery/reestablishment process, an RRC establishment/recovery/reestablishment completion message is received, where the RRC establishment/recovery/reestablishment completion message carries the measurement result.
Receiving an RRC establishment/recovery/reconstruction completion message in the process of establishing/recovering/reconstructing the RRC in the wireless resource control, wherein the RRC establishment/recovery/reconstruction completion message carries a result available indication; sending a measurement result reporting request to the terminal according to the result available indication; and receiving the measurement result sent by the terminal.
When reporting the measurement result for quick recovery to the network side, the UE can directly carry the measurement result in the RRC establishment/recovery/reestablishment complete message; or only carrying an available indication (available indicator) of the result in the RRC setup/recovery/reestablishment complete message, and then reporting the measurement result separately (for example, after the first network node receives the available indication, requesting the UE to report the measurement result).
Optionally, before step 11, the method further comprises: and sending the measurement configuration parameters after the measurement configuration negotiation of the first network node and the second network node to the terminal.
This embodiment is applied to RRC establishment/restoration of dual connectivity, where the first network node decides to release RRC connection with the UE in IDLE state or in INACTIVE state, and wants to configure the UE with measurements involving the second network node and the first network node for fast restoration of dual connectivity, a negotiation procedure of measurement configuration may be performed with the second network node, and specifically, the step of negotiation of measurement configuration between the first network node and the second network node may be implemented by, but is not limited to, the following manners:
in a first mode, sending a measurement configuration negotiation request to the second network node; receiving configuration information which is sent by the second network node and needs to be measured by the terminal; and integrating the configuration information and the configuration information of the first network node to obtain the measurement configuration parameters.
The second mode is that the recommended measurement configuration is sent to the second network node; receiving configuration information which is sent by the second network node and needs to be supplemented/corrected; and integrating the configuration information and the configuration information of the first network node to obtain the measurement configuration parameters.
Receiving configuration information which is sent by a second network node and needs to be measured by the terminal; and integrating the configuration information and the configuration information of the first network node to obtain the measurement configuration parameters.
The steps of measurement configuration negotiation and transmission between the first network node and the second network node are shown in fig. 2, after the measurement configuration negotiation between the first network node and the second network node, the first network node integrates the measurement configuration sent by the second network node with the measurement configuration of the first network node, and generates a measurement configuration parameter which is finally sent to the UE in the connection release process; the first network node releases the RRC connection of the UE to the IDLE state or the INACTIVE state, and the first network node sends an IDLE/INACTIVE state measurement configuration parameter for fast dual connectivity recovery, where the measurement configuration parameter may be carried in an RRC connection release message and sent to the UE, or broadcasted using system information. And after the UE enters an IDLE/INACTIVE state, executing measurement behaviors for rapidly recovering the dual connection according to the rule of the received measurement configuration parameters.
The integrating the configuration information and the configuration information of the first network node comprises:
the configuration information of the second network node and the configuration information of the first network node are integrated in a signaling to be carried independently; or, the configuration information of the second network node and the configuration information of the first network node are integrated into a set of measurement configuration parameters to be carried in a signaling.
It should be noted that, before the UE enters the IDLE/INACTIVE state, the first network node on the network side sends the measurement configuration parameter to the terminal, which may allow negotiation between the first network node and the second network node, and finally the first network node determines the measurement content to be sent to the UE and sends the measurement content to the UE; the first network node may also decide the measurement content to be delivered to the UE and directly send the measurement content to the UE.
Specifically, as shown in fig. 3, step 12 includes:
step 121, sending the measurement result related to the second network node; the first network node sends a modification/addition request to the second network node, wherein the modification/addition request carries a measurement result related to the second network node.
Step 122, receiving second network node configuration information fed back by the second network node according to the measurement result related to the second network node;
and after receiving the measurement result, the second network node makes a decision by itself and sends the decision to the cell related information configured by the UE, or refuses the second network node to modify/add, and feeds back the decision result to the first network node.
Step 123, sending a radio resource control RRC reconfiguration message to the terminal, where the RRC reconfiguration message includes the second network node configuration information;
if the first network node receives the configuration information of the second network node sent by the second network node, or the first network node determines to blindly configure the second network node/cell, the first network node issues the configuration information of the first network node and the second network node in RRC reconfiguration, and the dual-connection configuration for the UE is completed.
And step 124, receiving the reconfiguration complete message fed back by the terminal.
After receiving the network side configuration sent by the first network node, the UE feeds back a reconfiguration complete message to the first network node, and the first network node feeds back the reconfiguration complete message of the second network node to the second network node continuously.
The process of the first network node configuring dual connectivity for the terminal according to the measurement result is briefly described above, and will be further described with reference to the accompanying drawings:
for the RRC establishment/recovery process, after the UE establishes/recovers the RRC connection, the network side may directly use the measurement result of the UE to decide to add/recover the second network node without issuing the measurement configuration after the UE enters the connected state, and then waits for the UE to report the measurement result and then decides to add/recover the second network node, so that the UE can quickly establish/recover the dual connectivity after the RRC connection is established/recovered.
In the RRC connection establishment/recovery process, according to the measurement result, a process of configuring dual connectivity for the terminal is shown in fig. 4, where the UE performs measurement for fast recovery based on a rule of measurement configuration received before in an IDLE/INACTIVE state, and stores a relevant measurement result; the UE establishing/recovering an RRC connection with the first network node, which may be initiated by the first network node paging the UE, or a connection establishment/recovery initiated by the UE itself; the UE reports a measurement result for quick recovery to a first network node; after receiving the measurement result for fast recovery, the first network node that establishes/recovers the connection with the UE sends the measurement result related to the second network node, where:
if the first network node has negotiated measurement configuration with a second network node to which the UE was previously connected and the second network node maintains the context of the UE, then measurements relating to the second network node may be sent to the second network node, possibly using a second network node modification request to send to the second network node;
if the first network node does not perform measurement configuration negotiation with a second network node to which the UE was previously connected, and the second network node maintains the context of the UE, all measurement results received by the first network node may be sent to the second network node; or on the premise that the first network node knows all the frequency point information of the second network node, the measurement result of the frequency point related to the second network node is sent to the second network node. Sending, possibly using a second network node, a modification request to the second network node;
if the first network node decides to add a second network node to the UE (the second network node does not have the UE context), the first network node may send all measurement results received by the first network node to the second network node; or on the premise that the first network node knows all the frequency point information of the second network node, the measurement result of the frequency point related to the second network node is sent to the second network node. Possibly sent to the SN using a second network node add request.
The second network node makes a decision based on the measurement result and feeds the decision back to the first network node, and the first network node issues configuration information of the first network node and the second network node in RRC reconfiguration to complete double-connection configuration aiming at the UE; after receiving the network side configuration information, the UE feeds back a reconfiguration completion message to the first network node, feeds back a second network node reconfiguration completion message to the second network node by the first network node, and then executes a random access process with the second network node.
As for the RRC reestablishment process, according to the measurement result, the process of configuring dual connectivity for the terminal is shown in fig. 5, where the UE in the RRC connected state has a radio link failure/handover failure, which results in the RRC connection between the UE and the first network node being interrupted; in the RRC reestablishment process, the UE continues to perform measurement according to the RRM measurement configuration configured by the network before the radio link failure/switching failure; the UE and the first network node reestablish RRC connection, and report the measurement results obtained by the UE in the connection reestablishment process to the first network node after the connection reestablishment, and the measurement results can be used for the quick recovery of the dual-connection of the subsequent UE; after receiving the measurement result, the first network node which is connected with the UE in a reestablishing way sends the measurement result related to the second network node, wherein:
if the first network node decides to send a request to a second network node to which the UE was previously connected to restore dual connectivity, the measurement result corresponding to the previous measurement configuration of the second network node may be sent to the second network node, possibly using the second network node to modify the request to send to the second network node;
if the first network node decides to add a second network node to the UE (the second network node does not have the UE context), the first network node may send all measurement results received by the first network node to the second network node; or on the premise that the first network node knows all the frequency point information of the second network node, the measurement result of the frequency point related to the second network node is sent to the second network node. The request may be sent to the second network node using a second network node addition request.
The second network node makes a decision based on the measurement result and feeds the decision back to the first network node, and the first network node issues configuration information of the first network node and the second network node in RRC reconfiguration to complete double-connection configuration aiming at the UE; after receiving the network side configuration information, the UE feeds back a reconfiguration completion message to the first network node, feeds back a second network node reconfiguration completion message to the second network node by the first network node, and then executes a random access process with the second network node.
In the dual-connection configuration method of the embodiment of the present invention, the first network node receives a RRM measurement result obtained by measuring according to a measurement configuration parameter, where the measurement configuration parameter is related to the first network node and the second network node, and configures dual-connection for the terminal according to the measurement result, so that the dual-connection of the UE can be quickly recovered in an RRC establishment/recovery/reconstruction process.
As shown in fig. 6, an embodiment of the present invention further provides a dual connectivity configuration method, which is applied to a terminal, and includes:
step 61, sending a RRM measurement result of radio resource management to the first network node, where the RRM measurement result is obtained by measurement in an idle state/inactive state according to a measurement configuration parameter, and the measurement configuration parameter is related to the first network node and the second network node.
Aiming at the RRC establishment/recovery/reconstruction process, the UE carries out RRM measurement according to measurement configuration parameters in the IDLE state IDLE/INACTIVE state INACTIVE and connection reconstruction processes, and reports RRM measurement results to the first network node, wherein the measurement configuration parameters are related to the first network node and the second network node, and the RRM measurement results comprise measurement results related to the first network node and measurement results related to the second network node.
Specifically, in the RRC establishment/recovery process, the measurement configuration parameter according to which the UE performs the RRM measurement is issued by the first network node, and in the RRC reestablishment process, the measurement configuration parameter according to which the UE performs the RRM measurement is measurement configuration in a connected state before the radio connection failure. It should be noted that the first network node that sends the measurement configuration parameter and the first network node after RRC connection establishment/recovery/reestablishment may be the same network node or different network nodes; the second network node related to the measurement configuration parameter and the second network node after RRC connection establishment/recovery/reestablishment may be the same network node or different network nodes.

for the RRC re-establishment procedure, the UE reports all the saved measurement results (possibly including those that have not been reported before the radio link failure and those measured and evaluated for the cell in the re-establishment procedure) to the connected network side. The measurement configuration parameter for performing RRM measurement in the RRC reestablishment process is a connected RRM measurement configuration before a radio link failure, and the first network node and the second network node individually determine their respective measurement configurations.
Specifically, step 61 may be implemented by, but is not limited to, the following:

When reporting the measurement result to the first network node, the UE may directly carry the measurement result in an RRC establishment/recovery/reestablishment complete message; or only after the RRC setup/recovery/reestablishment complete message carries the result available indication, the UE is requested to report the measurement result separately (for example, the first network node requests the UE to report the measurement result after receiving the available indication).
Specifically, before the step of sending the RRM measurement result to the first network node, the method further includes:
and receiving the measurement configuration parameters after the first network node and the second network node are subjected to measurement configuration negotiation, wherein the measurement configuration parameters are sent by the first network node.

The measurement configuration parameters received before the UE enters the IDLE/active state may be obtained through negotiation between the first network node and the second network node, or may be measurement configuration parameters decided by the first network node; the measurement configuration parameters applied by the UE for measurement after the radio link fails are obtained before the radio link fails; the measurement configuration parameter is associated with the first network node and the second network node.
Specifically, after the step of sending the RRM measurement result to the first network node, the method further includes:
receiving a Radio Resource Control (RRC) reconfiguration message sent by a first network node, wherein the RRC reconfiguration message comprises second network node configuration information; and sending a reconfiguration complete message to the first network node after the reconfiguration is completed.
The UE executes measurement for quick recovery based on a rule of measurement configuration, relevant measurement results are stored, the UE establishes/recovers/reestablishes RRC connection with a network side, the measurement results are sent to a first network node, the first network node sends the measurement results relevant to a second network node to the second network node, the second network node feeds back configuration information of the second network node to the first network node, the first network node sends the measurement configuration parameters after integration processing to the UE, and after the UE receives the network side configuration sent by the first network node, the UE sends a reconfiguration completion message to the first network node after reconfiguration is completed.
