Description

Cell reconfiguration method, device, terminal and network equipment

Technical Field

The application belongs to the technical field of mobile communication, and particularly relates to a cell reconfiguration method, a cell reconfiguration device, a terminal and network side equipment.

Background

The dual connectivity (Dual Connectivity, DC) technology provides a terminal (also referred to as User Equipment (UE)) with resources of two network nodes, namely access network devices, one of which is referred to as Master Node (MN) and the other as Secondary Node (SN). At each network node, a carrier aggregation technique (CA), i.e. configuring a series of serving cells, also called Cell Groups (CG), controlled by the node for the UE, is used. MN controls the primary cell group (Master Cell Group, MCG) and SN controls the secondary cell group (Secondary Cell Group, SCG). Each Cell group contains a Special Cell (SpCell) and a series of Secondary cells (scells). The special Cell is called a Primary Cell (PCell) in the MCG, and the special Cell is called a Primary secondary Cell (Primary Secondary Cell, PSCell) in the SCG. SpCell uses the primary carrier in one cell group, while other secondary cells use the secondary carrier, and resource scheduling within one cell group is performed by SpCell.

In the process of changing the secondary cell group, for example, in the process of adding or changing the conditional primary and secondary cell groups (Conditional PSCell Addition or Change, CPAC), when the CPAC is completed once, the configured CPAC conditional configuration is released, the candidate cell is not reserved, the network side needs to wait for reconfiguring the CPAC conditional configuration, and the terminal can execute the CPAC based on the new conditional configuration. If the network does not reconfigure the CPAC condition configuration, the terminal has no opportunity to continue to execute the CPAC process based on the CPAC candidate cells configured before, and the terminal cannot perform cell switching in time. During a conditional primary-secondary cell change within a secondary node, the primary node may not be aware of the CPC configuration of the secondary node configuration and thus may not be able to instruct the terminal and or target secondary node to retain these CPC configurations.

Based on the first different conditions in the above examples, the present embodiment gives at least one of the following specific embodiments.

In one embodiment, the first condition is that the reconfiguration procedure does not change key information of the secondary node.

A1. The terminal receives a first configuration message from network side equipment, wherein the first configuration message comprises N groups of target configurations. And the terminal stores the N groups of target configurations.

A2. The terminal performs a reconfiguration procedure, which may be an SCG change procedure initiated by the network side device, or a CPC procedure.

A3. If the reconfiguration process does not change the auxiliary node key, namely the SN_key or the SKCoulter is not changed, the terminal reserves the N groups of target configurations; correspondingly, the network side equipment also reserves the N groups of target configurations.

If the reconfiguration process changes the auxiliary node key, namely, changes the SN_key or the SKCoulter, the terminal releases the N groups of target configurations; correspondingly, the network side equipment also releases the N groups of target configurations.

In another embodiment, the first condition includes that the reconfiguration procedure is a conditional primary-secondary cell change procedure in the secondary node and/or a primary-secondary cell change procedure in the secondary node, and the conditional primary-secondary cell change procedure in the secondary node is exemplified.

And under the condition that the execution condition in the target configuration is triggered, the terminal executes a conditional primary and secondary cell changing process in the secondary node, namely, the terminal performs CPC on the candidate primary and secondary cells corresponding to the target configuration triggered by the application.

B4. After completing CPC for the target configuration, the terminal reserves other N-1 group target configuration except the target configuration of the application, and releases the applied target configuration.

Accordingly, the network side device also reserves other N-1 group target configurations besides the target configuration of the application, and releases the applied target configuration.

In another embodiment, the first condition is a condition based on the first indication information and/or the second indication information.

C1. The terminal receives a first configuration message from network side equipment, wherein the first configuration message comprises N groups of target configurations. And the terminal stores the N groups of target configurations.

CPC configuration configured in nr-SCG cells;

CPC configuration configured in nr-second cell GroupConfig cells by SRB 1.

C2. The terminal obtains the first indication information and/or the second indication information from the network side equipment.

The first indication information and/or the second indication information may be carried by the first configuration message, or may be carried by other RRC reconfiguration messages, for example, may be carried by an RRC reconfiguration message in which the network side device initiates a reconfiguration procedure.

C3. For the second indication information, if the second indication information is acquired and indicated to be reserved, the terminal reserves the N target configurations; if the second indication information is not acquired or the acquired second indication information is indicated to be unreserved, the terminal releases the N target configurations;

and for the first indication information, the terminal indicates the first indication information as reserved target configuration to reserve, and releases the target configuration without the first indication information or with the first indication information as unreserved target configuration.

It should be understood that, in the case where the primary and secondary cells Cell Y applied by the reconfiguration procedure are the same as the candidate cells Cell X corresponding to a certain target configuration, the terminal does not reserve the certain target configuration.

As can be seen from the technical solutions of the foregoing embodiments, in the embodiments of the present application, by acquiring a first configuration message including a target configuration from a network side device, and determining whether to reserve and which target configurations to reserve based on different first conditions, a terminal reserves the target configurations according to different conditions after completing a reconfiguration process, so as to continue to perform a conditional primary and secondary cell change, reduce signaling load, and reduce interruption time of a secondary cell group change process, so as to adapt to a fast and changeable mobility environment.

Based on the above embodiment, optionally, before the reserving the M groups of target configurations, the method further includes:

acquiring key information corresponding to the target configuration from the network side equipment; the key information corresponding to the target configuration is applied under the condition that the target configuration is applied after the auxiliary node is changed.

Optionally, the network side device may determine whether to reserve the target configuration based on the first indication information and/or the second indication information, and provide key information, such as an SK Counter, for the target configuration that may be reserved. The key information is used for using the key information when the reserved target configuration is adopted after the secondary node change or the SCG release and re-addition SCG reconfiguration process occurs. For example, if the target configuration is applied after the CPC within the secondary node SN1 is executed, since no secondary node change occurs, the key information of the target configuration is not used; if the target configuration is applied after CPC between the secondary nodes is performed, key information of the target configuration needs to be used because a secondary node change from the secondary node SN2 to SN1 occurs.

D3. The terminal stores the N sets of target configurations, which may include key information, and first indication information and/or second indication information. After the terminal performs the reconfiguration process, the terminal may reserve M sets of target configurations, including key information corresponding to the target configurations, based on the first indication information and/or the second indication information.

D4. After the SCG change occurs, for example, triggering CPC between the auxiliary nodes, the network side device may send third configuration information to the target auxiliary node (T-SN), where the third configuration information includes the N sets of target configurations.

Based on the above embodiment, in the case where the inter-secondary-node change occurs, including the occurrence of a primary-secondary-cell change procedure between secondary nodes or a conditional primary-secondary-cell change procedure between secondary nodes, the method may include the following steps.

E1. The network side is configured with CPC configuration within the secondary node.

E2. After the primary and secondary cell change process between the secondary nodes or the conditional primary and secondary cell change between the secondary nodes occurs, the network side equipment sends second information to the source secondary node, where the second information is used to indicate the secondary node to change, and the source secondary node can send target configuration to be reserved.

In one embodiment, the second information may include at least one of:

a secondary cell group change message;

and the request message of the target configuration.

E3. After receiving the second information, the source auxiliary node sends first information to the network side equipment, wherein the first information can comprise target configuration reserved by the source auxiliary node, so that the network side equipment can determine the N groups of target configuration based on the first information.

In one embodiment, the first information includes at least one of:

a list of target candidate cells;

……

S7, the master node sends RRC reconfiguration information (RRCreconfiguration message) containing CPAC commands to the terminal.

S8, the terminal master node sends a reconfiguration complete message (RRCreconfiguration complete message) to confirm that the RRC reconfiguration message is received.
