Technical Field

Background

In the related art, for a multi-connection scenario, if a terminal measures multiple target cells with better quality and the terminal supports multiple connections, a target node (may also be referred to as a target base station) may configure the multiple connections of the terminal at the target base station in advance in a handover process, so that the terminal can perform multiple connections immediately after switching to the target cell. Taking the dual-connection handover scenario as an example, as shown in fig. 1, if the dual-connection has been started at the source node (may also be referred to as a source base station) terminal, and the secondary node (may be referred to as SN or secondary base station) or the primary and secondary cell (may be referred to as PScell or secondary cell group) measured by the terminal during the handover process, the signal quality of the source primary node (may be referred to as MN or primary base station) or the primary cell (may be referred to as PCell or primary cell group) or the primary cell group (may be referred to as Master Cell Group or referred to as MCG) is not good enough, the target primary node and the secondary node may perform the addition of the secondary node or primary and secondary cell group in advance, so that the secondary node or primary and secondary cell group is not changed during the process of replacing the primary node, and the secondary node or primary and secondary cell group is maintained, so that the terminal may obtain a high service rate of the dual-connection or secondary cell group immediately after the handover.

In a multi-connection scenario, how to quickly recover the wireless connection by the terminal becomes a problem to be solved.

Detailed Description

The present application is described in further detail below with reference to the accompanying drawings and examples.

Before describing embodiments of the present application, terms in the embodiments of the present application are defined:

1. a main node, providing control plane connection to the core network for the terminal in multiple connections;

2. an auxiliary node, which provides services for the terminal except for control plane connection to the core network in multiple connections;

3. A primary cell group, a set of serving cells associated with the primary node, including a primary cell and optionally one or more secondary cells;

4. a primary cell, a primary cell in a primary cell group;

5. a secondary cell group, a set of serving cells associated with a secondary node, comprising a primary secondary cell and optionally one or more secondary cells.

6. Primary and secondary cells, primary cells in a secondary cell group.

Related art, besides the normal handover, two handover enhancement techniques are introduced: DAPS switch and conditional switch (english may be expressed as Conditional Handover, CHO for short).

The DAPS handover is a mechanism for enabling a terminal to simultaneously keep data with a source node and a target node in a handover process, that is, the terminal receives data of the source node in a downlink (english may be expressed as DL) until the source node receives a handover success message sent by the target node, and the terminal sends data to the source node in an uplink (english may be expressed as UL) until the terminal is successfully randomly accessed in the target cell, and then switches uplink transmission to the target cell. Through the DAPS switching mechanism, the data surface of the terminal can not generate abrupt reduction of the speed due to switching, and the service experience of the terminal is improved.

In the DAPS handoff scenario, there are three cases:

1) When a radio link failure (RLF, radio Link Failure) occurs in the source cell, the terminal stops uplink and downlink data transmission with the source cell and releases the connection with the source cell, but retains radio resource control (RRC, radio Resource Control) reconfiguration information of the source cell.

2) If the terminal fails to switch in the target cell, the terminal can fall back to the configuration of the source cell, keep connecting with the source cell, and report the indication information of the DAPS switching failure through the source cell. Here, since the connection between the terminal and the source base station is unreliable and cannot report too much information, the terminal only reports the indication information, but does not report other information such as measurement results.

3) If the terminal generates RLF in the source cell and then fails DAPS handover in the target cell, the terminal performs cell selection and then initiates a reestablishment process.

Conditional handover is a mechanism to enhance the robustness of the handover. The basic idea of conditional switching is: in order to solve the problem that the terminal cannot normally complete the handover process due to sudden degradation of the channel between the terminal and the serving cell (especially for the high frequency situation), the base station may configure the terminal to trigger measurement reporting at a lower threshold, and carry a higher threshold for triggering handover in the handover command (also referred to as HO command). And, the handover command may also carry a random access resource used by the terminal in the target cell, and once the handover threshold is met, the terminal initiates a random access procedure to the target cell. In addition, the source base station may configure the terminal with conditional handovers for multiple target cells. When the terminal fails to perform the conditional handover, the terminal performs cell selection, and if the selected cell is a candidate cell for the conditional handover, the terminal can access the target cell by using a pre-configured resource; and if the selected cell is not the candidate cell for conditional handover, the terminal executes a reestablishment flow.

In summary, in the related art, if the normal handover fails, the terminal performs cell reestablishment, the RRC connection is slowly recovered, and the information related to the failure (handover failure report that may include information such as the identifier of the source cell, the identifier of the target cell, and the measurement result) can be reported to the network side after the terminal RRC connection. Similarly, in the condition switching process, if the condition switching fails, and the cell selected by the terminal is not a candidate target cell for the condition switching, the terminal executes the reestablishment process, the RRC connection is recovered slowly, and the failed related information can be reported to the network side after the terminal is RRC connected; in the switching process of the DAPS, if the terminal generates RLF in the source cell and/or fails in the DAPS switching in the target cell, the terminal cannot report the measurement information related to failure to the network side in time, so that the network side cannot help the terminal to quickly recover the RRC connection.

On the other hand, if the above technical solution is adopted for a multi-connection scenario, the above problems also exist.

Based on the above, in various embodiments of the present application, in a multi-connection scenario, a terminal reports related information of wireless connection failure to a master node through an auxiliary node; therefore, the network side can help the terminal to recover the RRC connection with the source base station and/or the target base station as soon as possible based on the information reported by the terminal, so that the user experience can be improved.

An embodiment of the present application provides an information reporting method, as shown in fig. 2, including:

step 201: when the terminal determines that the wireless connection of the first cell or the first cell group fails, first information is sent to the auxiliary node;

step 202: the auxiliary node receives the first information and sends the first information to a main node;

step 203: the main node receives first information sent by the terminal through the auxiliary node;

wherein the first information comprises at least one of:

the related identity of the first cell or cells of the first cell group;

cell quality measured by the terminal;

Here, in practical application, the solution of the embodiment of the present application may be applied to a multi-connection scenario, that is, the terminal supports multiple connections. In addition, the multi-connection scenario may exist in two cases:

1) The master node is switched, and the terminal generates RRC connection failure in a source cell and/or a target cell;

2) The primary node does not switch, but the primary node or part of the secondary nodes fail in RRC connection.

It can be appreciated that the connection quality between the terminal and the secondary node is higher than the connection quality between the terminal and the primary node; therefore, under the multi-connection scene, no matter whether the terminal is switched or not, when the terminal fails in RRC connection with the network side, the auxiliary node (compared with the main node, the wireless connection quality is better) reports the related information of the connection failure to the network side, so that the network side can help the terminal to recover the RRC connection with the corresponding network side node as soon as possible, and the user experience is improved.

In practical application, the terminal may also be referred to as a User Equipment (UE), and may also be referred to as a User; the secondary node may also be referred to as a secondary base station; the master node may also be referred to as a master base station; in the case of a handover of the master node, the master node may comprise a source master node and/or a target master node; the source master node may also be referred to as a serving master node, a source master base station, or a serving master base station; the target master node may also be referred to as a target master base station.

In practical application, the radio connection failure includes an RRC connection failure.

The first cell may be a primary cell; the first cell group may be a master cell group. Here, in practical application, when the radio connection of the primary cell in the first cell group fails, or the radio connection of both the primary cell and the secondary cell in the first cell group fails, the terminal determines that the radio connection of the first cell group fails.

In step 201, the terminal may send the first information to the secondary node through a message such as primary cell failure information (english may be expressed as MCG Failure Information), an Xn interface establishment REQUEST (english may be expressed as Xn SETUP REQUEST), and a radio access network node configuration update (english may be expressed as NG-RAN NODE CONFIGURATION UPDATE), which is not limited in this embodiment of the present application.

In practical applications, the relevant cell identifier may include a physical cell identifier (PCI, physical Cell Identifier), which is not limited in this embodiment of the present application.

In practical application, the type of the cell quality measurement result specifically included in the first information may be set according to requirements, which is not limited in the embodiment of the present application. The first information may include, for example, the quality of all cells measured by the terminal, or may include only the quality of cells in which radio connection failure occurs, that is, the quality of the first cell or the cells of the first cell group; for another example, the cell quality may specifically include the quality of the source primary cell, the target primary cell, the primary and secondary cells on the secondary node, and the secondary cells. Wherein the quality of the cell may be referred to as the signal quality of the cell.

When it is determined that the radio connection of the first cell fails, the first information includes at least one of the following;

a related identity of the first cell;

cell quality measured by the terminal;

second information characterizing whether the first cell is a primary cell or a primary secondary cell;

When it is determined that the radio connection of the first cell group fails, the first information includes at least one of:

a correlation identity of cells of the first cell group;

cell quality measured by the terminal;

second information characterizing whether the first cell group is a primary cell group or a secondary cell group;

In practical application, the relevant identifier of the cell of the first cell group may include PCIs of all cells in the first cell group, which is not limited in the embodiment of the present application.

In an embodiment, the third information may include one of:

a normal handover, a so-called handover;

Switching conditions;

DAPS switching;

switching based on DAPS and conditions, i.e. DAPS and condition switching are configured simultaneously;

a master node or a master cell group or a master cell connection fails;

Wherein, when it is determined that the radio connection of the first cell or the first cell group fails, and the third information characterizes a type of the terminal handover when the radio connection failure occurs, the third information may include one of:

ordinary switching;

switching conditions;

DAPS switching;

switching based on DAPS and conditions.

When it is determined that the radio connection of the first cell fails, and in case the third information characterizes the type of the terminal failure when the radio connection failure occurs, the third information may include one of the following:

the connection of the master node or the master cell fails;

the secondary node or primary and secondary cell fails to connect.

When it is determined that the radio connection of the first cell group fails, and in the case that third information characterizes the type of terminal failure when the radio connection failure occurs, the third information may include one of:

failure of primary cell group connection;

the secondary cell group fails to connect.

In practical application, if the terminal fails in wireless connection when executing the conditional switching, the triggering event (i.e. the satisfied event) of the conditional switching and/or the threshold corresponding to the event may also be reported to the master node by the auxiliary node.

Based on this, in an embodiment, in a case where the type of the terminal handover includes a conditional handover when the third information characterizes a radio connection failure, the first information may further include:

Illustratively, the fourth information may include an A3 event, an A5 event, and corresponding threshold values.

In step 202, in the case of handover, the secondary node may send the first information to the source primary node and/or the target primary node after receiving the first information in the actual application.

Based on this, in an embodiment, in a case where the first information includes the third information, the sending the first information to the master node may include:

and the auxiliary node sends the first information to a source main node and/or a target main node.

In practical application, under the condition that the first information contains the third information and the cell quality measured by the terminal, the auxiliary node can select to forward the first information to a source main node and/or a target main node according to the measurement result of the terminal on the cell quality.

For example, in the case that the measurement result quality of the source master node is higher than that of the target master node, the secondary node may forward only the first information to the source master node due to a low success rate of the terminal successfully accessing the target master node. And in the case that the measurement result quality of the source master node side is lower than the measurement result quality of the target master node side, the secondary node may forward only the first information to the target master node. In this way, only the master node that receives the first information can reconfigure the wireless connection to the terminal.

In practical application, for the multi-connection scenario, if part of auxiliary nodes fail in RRC connection, the auxiliary node with higher RRC connection quality (compared with the main node and/or other auxiliary nodes, the auxiliary node with better wireless connection quality) receives the first information reported by the terminal, and then forwards the first information to the main node.

In step 203, during actual application, the source master node and/or the target master node may negotiate with the auxiliary node to reconfigure the wireless connection to the terminal; in other words, the source master node and/or the target master node may determine the configuration of the wireless connection by the secondary node, the source master node or the target master node for the terminal again by performing information interaction with the secondary node.

Based on this, in an embodiment, the method may further include:

and the auxiliary base station performs information interaction with the source main node and/or the target main node to determine the configuration of the wireless connection of the terminal by the auxiliary node, the source main node or the target main node.

Here, in the case that the master node includes only a source master node, the source master node may determine a configuration of re-wirelessly connecting the terminal by the secondary node or the source master node by performing information interaction with the secondary node;

in the case that the master node only includes a target master node, the target master node may perform information interaction with the auxiliary node to determine a configuration of re-performing wireless connection on the terminal by the auxiliary node or the target master node;

and under the condition that the master node comprises a source master node and a target master node, information interaction can be carried out among the source master node, the target master node and the auxiliary node so as to determine the configuration of wireless connection of the terminal again by the auxiliary node, the source master node or the target master node.

In actual application, under the condition that the main node is determined to carry out wireless connection reconfiguration on the terminal again, the main node needs to inform the auxiliary node of carrying out wireless connection reconfiguration on the terminal again by a source main node or a target main node.

Based on this, in an embodiment, in a case where the first information includes third information and the configuration of the wireless connection is performed again by the master node on the terminal, the method may further include:

the master node transmits sixth information to the slave node, the sixth information characterizing a configuration of re-wireless connection of the terminal by the master node, in other words, the sixth information characterizing a configuration of re-wireless connection of the terminal by a source master node or a target master node;

and the auxiliary node receives sixth information sent by the source main node or the target main node.

Here, in the case where it is determined that the configuration of the wireless connection to the terminal is re-performed by the target master node, the target master node may also notify the source master node that the configuration of the wireless connection to the terminal is re-performed by the target master node; in the case that it is determined that the configuration of the wireless connection to the terminal is re-performed by the source master node, the source master node may also notify the target master node that the configuration of the wireless connection to the terminal is re-performed by the source master node.

In practical application, the judging condition for determining whether the source master node or the target master node carries out wireless connection configuration on the terminal again can be set according to requirements.

For example, in a case where the quality of one or more cells on the target primary node side is higher than the quality of the cells on the source primary node side in the measurement result included in the first information, or in a case where the quality of the cells on the target primary node side is similar to the quality of the cells on the source primary node side but the load (load) of the cells on the target primary node side is lower, it may be determined that the configuration of the radio connection is performed again by the target primary node on the terminal, so that the terminal has a higher possibility of recovering the radio connection of the primary cell group.

In an exemplary case that the radio connection fails when the terminal performs the conditional handover, it may be determined that the source master node performs radio connection configuration on the terminal again, and specifically, the source master node may configure a trigger event and/or a corresponding threshold of a new conditional handover for the terminal, or configure information such as a new target primary cell and an access resource for the terminal.

When the wireless connection of the source main node fails, the terminal indicates that the terminal has too late handover, and the source main node can configure a trigger event of new conditional handover and/or a corresponding Threshold according to a measurement result of the terminal, for example, adjust down an A3-Offset parameter of an A3 event, or adjust up an A5-Threshold1 parameter of an A5 event and/or adjust down an A5-Threshold2 parameter of the A5 event, so that the terminal can be switched to a target cell earlier; or the source master node may also configure the terminal with information such as a new target primary cell and access resources.

When the terminal fails to switch, the terminal is indicated to switch prematurely, the source main node can configure a trigger event of new conditional switching and/or a corresponding Threshold according to the measurement result of the terminal, for example, the A3-Offset parameter of the A3 event is adjusted up, or the A5-Threshold1 parameter of the A5 event is adjusted down and/or the A5-Threshold2 parameter of the A5 event is adjusted up, so that the terminal can switch to the target cell later; or the source master node may also configure the terminal with information such as a new target primary cell and access resources.

In actual application, under the condition that the secondary node is determined to carry out wireless connection reconfiguration on the terminal again, the secondary node needs to inform the primary node of the wireless connection reconfiguration on the terminal again by the secondary node.

Based on this, in an embodiment, in a case where the first information includes third information and the configuration of the wireless connection is performed again by the secondary node on the terminal, the method may further include:

the auxiliary node sends seventh information to the source main node and/or the target main node, wherein the seventh information characterizes the configuration of wireless connection of the terminal by the auxiliary node;

The master node (i.e., the source master node and/or the target master node) receives the seventh information sent by the secondary node.

In practical application, if the cell quality of the secondary node side in the measurement result included in the first information is higher than the cell quality of the source primary node and the target primary node side, the secondary node may configure itself as a new primary node, configure a primary secondary cell or a secondary cell as a new primary cell, and send the seventh information to the source primary node and/or the target primary node.

In practical application, when the secondary node, the source master node or the target master node determines that the cell quality of the secondary node, the source master node and the target master node is relatively poor (for example, the cell quality is determined not to meet a preset condition, the condition characterizes that the cell quality is relatively good), or the cell load is excessively large (for example, the cell load is larger than a preset threshold), the wireless connection established with the terminal can be determined to be released.

Based on this, in an embodiment, the method may further include:

the auxiliary node releases the wireless connection established with the terminal;

and/or the number of the groups of groups,
