It should be noted that the wireless communication system 100 shown in fig. 1 is only for more clearly illustrating the technical solution of the present application, and does not constitute a limitation to the present application, and as a person having ordinary skill in the art knows, the technical solution provided in the present application is also applicable to similar technical problems as the network architecture evolves and new service scenarios emerge.
The related art to which the present application relates is described below.
The existing dual connectivity architecture can only support Master Nodes (MN) and Secondary Nodes (SN). if a terminal wants to configure more secondary cells scells, when measurement reports, because PCI cannot distinguish the association between cells and base stations, the cells configured by the terminal may not be secondary nodes but may be cells of different base stations in the neighboring area.
In view of the above problems, the embodiments of the present application propose the following embodiments, which are described in detail below with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a configuration method of types of secondary cell groups, which is applied to the above exemplary communication system and provided by the embodiment of the present application, and the method includes:
in part 201, the terminal measures or more cells of an th node to obtain a measurement report, wherein the measurement report comprises correspondence between the or more cells and a base station identifier of the th node;
the signal coverage of the serving cell of the th node includes the current location of the terminal, and the node to which the cell whose signal coverage does not include the current location of the terminal belongs is a second node, which is not in the measurement range of the terminal in the present application.
The terminal may include a millimeter wave terminal supporting dual transmission links, and the base station identifier includes an evolved node identifier eNB ID or a node identifier gNB ID of a new wireless system, and the like, which is not limited herein to only.
In part 202, the terminal sends the measurement report to a network device, where the measurement report is used for the network device to configure a secondary cell group for the terminal according to the correspondence.
It can be seen that, in this embodiment of the present application, a terminal first measures or multiple cells of an th node to obtain a measurement report, and then sends the measurement report to a network device, where the measurement report includes a correspondence between or multiple cells and a base station identifier of the th node, so that the measurement report may be used by the network device to rapidly configure an auxiliary cell group for the terminal according to the correspondence, that is, through the enhanced measurement mechanism, the terminal can preferentially measure and report cells belonging to the same base station, so that the base station can rapidly configure an auxiliary cell for the terminal, thereby accelerating the configuration of the auxiliary cell, shortening handover or configuration delay, and improving the utilization rate of the auxiliary cell.
Before the terminal measures or more cells of the node in possible examples, the method further includes autonomously reading system information to obtain a base station identity of the node.
The system information may be, for example, a Cell Global identity, if an E-UTRAN Cell Global identity (E-CGI) or an NR Cell Global identity (N-CGI), or other forms of Cell Global identities.
In specific implementation, the terminal may trigger a measurement process in advance, and autonomously read system information such as a neighboring cell in advance to obtain a base station identifier. That is, the terminal can autonomously measure cells and analyze correspondence between the cells and the base stations, statistically classify the measured cells, and if the terminal detects 2 cells Cell1 and Cell2 on node 1 and 1 Cell3 on node 2, the terminal may generate a measurement report, which may carry the correspondence between the Cell1, Cell2 and the base station identifier of node 1 and the correspondence between the Cell3 and the base station identifier of node 2, and send the measurement report to the network device.
As can be seen, in this example, the terminal can autonomously read the system information to obtain the base station identifier of the th node, and measure the cell of the th node, and a cell measurement process limited by the network side does not need to be performed according to specific base station identifier information in the measurement configuration sent by the base station, which is more flexible and efficient.
In this possible example, before the terminal supports dual connectivity and is in a dual connectivity state and autonomously reads system information to obtain the base station identity of the th node, the method further includes the terminal receiving a th message from the network device, where the th message is used to notify that a primary node MN or a secondary node SN is updated.
The terminal supports the update of the main node MN and the update of the SN of the auxiliary node, or the update of the SN of the MN is not changed.
For example, assuming that the network device determines that the terminal updates the MN, that is, the MN updates the SN unchanged, the terminal autonomously reads the system information to obtain the identifier of the th node, measures or more cells under the th node, and adds the correspondence between the or more cells and the th node in the generated measurement report, where the th node is a node other than the current MN of the terminal.
For another example, assuming that the network device determines that the terminal updates the SN, that is, the MN does not change the SN update, the terminal autonomously reads the system information to obtain the identifier of the th node, measures or more cells under the th node, and adds the correspondence between the or more cells and the th node in the generated measurement report, where the th node is a node other than the current SN of the terminal.
As can be seen, in this example, for a terminal supporting dual connectivity and in a dual connectivity state, the terminal can trigger an operation of autonomously reading system information to obtain a base station identifier of a th node when receiving an th message from the network device and determining to update an MN or an SN, so as to implement a measurement process initiated in advance, facilitate the terminal to preferentially measure and report cells belonging to the MN or the SN, so that the base station can rapidly configure an auxiliary cell to the terminal, thereby shortening a handover or configuration delay and improving a utilization rate of the auxiliary cell by accelerating configuration of the auxiliary cell.
In this possible example, before the terminal autonomously reads system information to obtain the base station identifier of the th node, the method further includes that the terminal receives a second message from the network device, where the second message is used to notify that an auxiliary node SN is established.
When the terminal is in the single connection state, only the MN is configured, and the SN is not configured.
For example, the network device determines that the SN is configured for the terminal, then sends a second message to the terminal, and after receiving the second message and determining that the SN is configured, the terminal autonomously reads the system information to obtain the base station identifier of the th node, measures or more cells under the th node, and adds the measured corresponding relationship between or more cells and the corresponding base station identifiers in the measurement report.
As can be seen, in this example, for a terminal supporting dual connectivity and in a single connectivity state, when receiving a second message, the terminal can trigger an operation of autonomously reading system information to obtain a base station identifier of an th node, so as to implement a measurement process initiated in advance, and facilitate the terminal to preferentially measure and report cells belonging to the same base station, so that the base station can rapidly configure an SN base station and an auxiliary cell thereof for the terminal, thereby shortening configuration delay and improving the utilization rate of the auxiliary cell by accelerating the configuration of the auxiliary cell.
In the example of the instinct, before the terminal autonomously reads system information to obtain the base station identifier of the th node, the method further includes the steps of establishing an RRC connection by the terminal, receiving and pre-storing measurement configuration from the network equipment through the RRC connection, wherein the measurement configuration is used for indicating the terminal to determine the base station identifier of the detected node when the terminal performs cell measurement, reporting the corresponding relation between the base station identifier and the corresponding detected cell when preset conditions are met, releasing the RRC connection, and switching to an idle state.
For the idle terminal, if a plurality of secondary cells are configured when the terminal is started, measurement can be performed in advance. The preset conditions include: reporting a measurement report if the number of measured cells is greater than or equal to a preset number (e.g., 3); alternatively, when a preset Timer (e.g., 100 seconds) is completed, a measurement report is reported
It can be seen that, in this example, for an idle terminal, configuration information of a network side may be stored through RRC connection before switching to an idle state, so that after switching to the idle state, an operation of autonomously reading system information to obtain a base station identifier of an th node may be triggered, thereby implementing a measurement process initiated in advance, facilitating a terminal to preferentially measure and report cells belonging to the same base station , so that the base station can rapidly configure a serving primary cell and a serving secondary cell to the terminal, thereby shortening a configuration delay and improving a utilization rate of the secondary cell.
Before the terminal measures or more cells of the node in possible examples, the method further includes the terminal receiving a measurement configuration from a network device, the measurement configuration including a base station identification of the node.
The base station identifier carried in the measurement configuration configured for the terminal by the network device is used for indicating a base station corresponding to the cell measurement process.
As can be seen, in this example, since the th node is configured by the network side, that is, the network side can measure the selected base station by actively configuring the terminal, so as to implement a more accurate cell measurement process, avoid measuring and reporting a cell that cannot be added as an auxiliary cell, and improve measurement efficiency.
In this possible example, the terminal supports dual connectivity DC and is in dual connectivity state, and the th node is a primary node MN and/or a secondary node SN of the terminal.
For example, if the network device determines that or more cells are added to the SN by the terminal, the network device instructs the terminal to add cells to the SN, the terminal obtains the notification and then measures or more cells under the SN to obtain a measurement report, and the measured correspondence between or more cells and the base station identifier of the SN is added to the measurement report.
For another example, assuming that the network device determines that or more cells are added to the MN by the terminal, the network device instructs the terminal to add cells to the MN, after obtaining the notification, the terminal measures or more cells under the MN to obtain a measurement report, and adds the measured correspondence between or more cells and the base station identifier of the MN in the measurement report.
It can be seen that, in this example, for a terminal supporting dual connectivity and in a dual connectivity state, when the terminal is notified by a network side to add a cell to an MN or an SN, a process of performing cell measurement under a node that needs to add a cell is triggered, so that the terminal can preferentially measure and report the cell belonging to the MN or the SN, so that a base station can rapidly configure an auxiliary cell to the terminal, thereby shortening configuration delay and improving utilization rate of the auxiliary cell by accelerating configuration of the auxiliary cell.
In this possible example, the terminal supports dual connectivity DC and is in dual connectivity state, and the th node is a node of the terminal except for a primary node MN and a secondary node SN;
the th node is determined as the main node after the terminal performs the main node update, or determined as the auxiliary node after the terminal performs the auxiliary node update.
For example, assuming that the network device determines that the terminal updates the MN, that is, the MN updates the SN unchanged, the terminal is notified th node of the bs id, the terminal measures or more cells under the th node, and adds the correspondence between the or more cells and the th node of the bs id in the measurement report.
For another example, assuming that the network device determines that the terminal updates the SN, that is, the MN does not change the SN update, the terminal is notified th node of bs id, the terminal measures or more cells under the th node, and adds the correspondence between the or more cells and the th node of bs id in the measurement report.
It can be seen that, in this example, after determining that the MN or SN of the terminal needs to be updated, the network side may trigger the cell measurement process of the terminal by sending the node identifier of the th node to the terminal, so that the terminal can preferentially measure and report cells belonging to the same base station, so that the base station can rapidly configure a new MN or SN and an auxiliary cell thereof, thereby shortening a handover or configuration delay and improving the utilization rate of the auxiliary cell.
In this possible example, the terminal supports dual connectivity DC and is in a single connectivity state, the th node is a node other than the current primary node MN of the terminal, and the th node is determined to be a secondary node SN of the terminal.
Wherein, which base station the terminal configures as the secondary node SN needs to be determined by the network device according to the measurement result.
As can be seen, in this example, for a terminal supporting dual connectivity and in a single connectivity state, after determining that the terminal needs to set an SN, a network side may send a node identifier of an th node to the terminal to trigger a cell measurement process of the terminal, so that the terminal can preferentially measure and report cells belonging to the same base station , so that the base station can rapidly configure an SN auxiliary node and an auxiliary cell thereof to the terminal, thereby shortening a handover or configuration delay and improving a utilization rate of the auxiliary cell by accelerating the configuration of the auxiliary cell.

in part 301, a network device receives a measurement report from a terminal, wherein the measurement report is obtained by measuring or more cells of an th node, and the measurement report comprises correspondence between the or more cells and a base station identification of the th node;
and in part 302, the network equipment configures an auxiliary cell group for the terminal according to the corresponding relation.
It can be seen that, in the embodiment of the present application, the network device receives a measurement report reported by the terminal, where the measurement report is obtained by the terminal measuring or multiple cells of the th node, and the measurement report includes a correspondence between or multiple cells and a base station identifier of the th node, so that the network device can configure an auxiliary cell group for the terminal according to the correspondence in the measurement report, that is, through the enhanced measurement mechanism, the terminal can preferentially measure and report cells belonging to the same base station, so that the base station can rapidly configure the auxiliary cell for the terminal, thereby shortening handover or configuration delay and improving the utilization rate of the auxiliary cell by accelerating the configuration of the auxiliary cell.
In possible examples, the base station identity is obtained by the terminal autonomously reading system information.
In the possible example, the terminal supports dual connectivity and is in a dual connectivity state, and before the network device receives the measurement report from the terminal, the method further comprises the network device sending th message to the terminal, wherein the th message is used for notifying the update of the primary node MN or the secondary node SN.
In this possible example, the terminal supports dual connectivity and is in a single connectivity state; before the network device receives the measurement report from the terminal, the method further includes: and the network equipment sends a second message to the terminal, wherein the second message is used for notifying the establishment of the auxiliary node SN.
