[0048] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0049] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] For ease of understanding, some contents involved in the embodiments of the present application are described as follows:

[0052] 1) Introduction to UE historical information

[0053] UE historical information is divided into UE historical information recorded by the network side and UE historical information recorded by the UE. The content includes information such as the cell where the UE resides / accesses and the length of time it resides, which is used to solve the problem of ping-pong switching.

[0054] The UE history information maintained by the network side includes the cell identifiers of each PCell cell and the corresponding PSCell and the corresponding access time information of the UE in the connected state. During handover, the handover request message is sent to the handover target base station, and the handover target base station continues to maintain it. Since the base station is not aware of the terminal's idle state, the UE history information maintained by the network side does not include the UE information in the idle state.

[0055] The network side records UE historical information, which is divided into two cases: distributed base stations and integrated base stations. For distributed base stations, the central unit (CU) records UE historical information. Each time the distributed unit (DU) notifies the CU of a cell change through the interface, the CU will record the UE historical information. For integrated base stations, the base station is responsible for recording UE historical information.

[0056] The UE history information maintained by the terminal includes the information records of the PCell and the corresponding PSCell in the idle state and the connected state. It requires the support of the terminal capability and is obtained by the network side through dedicated signaling messages.

[0057] 2) Multi-Rate Dual Connectivity (MR-DC) network architecture

[0058] In a multi-connection architecture, a UE may be connected to a master node (MN) and one or more secondary nodes (SN), and perform signaling and / or data interaction with these network nodes. Both the MN and SN nodes can be LTE / e-LTE / NR nodes. When there is one MN node and one SN node, it is called dual connection (DC).

[0059] When the UE is in a connected state, it can be connected to one or more network nodes, and the network nodes can be in one or more radio access technologies (Radio Access Technology, RAT). For example, when the MN is an LTE node and the SN is an NR node, it is (NG) EN-DC dual connection; when the MN is an NR node and the SN is an LTE node, it is NE-DC dual connection; when both the MN and the SN are NR nodes, it is NR-NR-DC.

[0060] SCG is a service cell group under the SN node under MR-DC, including a PSCell and one or more possible secondary cells (Secondary Cell, Scell).

[0061] For the UE historical information maintained by the base station, the SN node is responsible for collecting the UE historical information related to the PSCell and sending it to the MN through the XN / X2 interface message. The MN generates the UE historical information containing the PCell and PSCell information according to the corresponding time information, as shown in Table 1 below.

[0062] Table 1

[0063]

[0064] In the UE history information, PCell and PSCell are associated and correspond in time. In the above table, the UE accesses PCellA and stays for time A. At the same time, the UE establishes dual connections to access PSCell a and stays for time a; then deletes the dual connection and maintains time b under single connection; then establishes dual connections to access PSCell c and stays for time c; then PSCell changes from PSCell c to PSCell d and stays for time d; then deletes the dual connection and maintains time e under single connection. Then PCell switches from PCell A to PCell B and maintains single connection.

[0065] As shown in the table above, the UE history information is a two-dimensional structure. The first dimension PCell list contains up to 16 nodes, that is, records the information of 16 cells. The second dimension PSCell list corresponding to each PCell node contains up to 8 nodes, that is, records the information of 8 cells. If the recorded cell information reaches the upper limit, the oldest cell record information will be deleted and replaced with the current record, that is, it is always the cell information of the most recent time period.

[0066] The UE history information maintained by the terminal is also a two-dimensional structure, and its structure and content are similar to the above table, but the PCell list under two dimensions and the PSCell list corresponding to each PCell both contain a maximum of 16 nodes, that is, the information of 16 cells is recorded. When the upper limit is reached, the processing is the same as above.

[0067] 3) Enhanced mobility

[0068] The switching triggered by Layer 1 (Layer 1) and Layer 2 (Layer 2) is a switching candidate cell pre-configured by Layer 3 (Layer 3). Based on the measurement reporting information of Layer 1 and Layer 2, the network sends Layer 1 and Layer 2 signaling to trigger the UE to switch between candidate cells once or multiple times. Different from the traditional measurement configuration and reporting information based on Radio Resource Management (RRM), the switching triggered by sending Layer 3 switching commands can realize continuous, repeated and fast switching between multiple cells. The switching triggered by Layer 1 and Layer 2 can also be applied to SCG, that is, the change of PSCell can be triggered based on Layer 1 and Layer 2.

[0069] SCG continuous PSCell cell change also pre-configures multiple PSCell candidate cells and execution conditions at layer 3. The UE evaluates the execution conditions and implements the PSCell change when the conditions are met. It then saves the configuration and continues to evaluate the execution conditions. When the conditions are met, it continues to execute the PSCell change until the subsequent (subsequent) conditional primary and secondary cell addition or change (Conditional Pscell Addition / Change, CPAC) configuration is released.

[0070] MCG continuous PCell cell switching is similar to SCG continuous PSCell cell change. It also pre-configures multiple PCell candidate cells and execution conditions. The UE evaluates the execution conditions and implements PCell switching when the conditions are met. Then it saves the configuration and continues to evaluate the execution conditions. When the conditions are met, it continues to execute PCell switching until the continuous switching configuration is released.

[0071] For switches triggered by layer 1 and / or layer 2, or MCG continuous PCell switches, or SCG continuous PSCell cell changes, if the relevant information of these switches is also recorded in the UE historical information, it will not only occupy the storage space of the UE historical information, but will also cause the network to misjudge that these switches have ping-pong switching problems, thereby avoiding incorrect optimization of switching configuration parameters.

[0072] The embodiment of the present application provides a method and device for processing historical information. The method and device are based on the same application concept. Since the method and device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0073] like Figure 1 As shown, a historical information processing method provided by an embodiment of the present application includes:

[0074] Step 101: The first device determines whether a specific handover or change occurs in a cell.

[0075] In this step, the first device determines whether a specific switching or change occurs for the switching or change of the terminal cell, so as to be able to perform corresponding processing for the scenario where the switching or change occurs. The specific switching or change of the cell is a scenario where the ping-pong switching judgment based on the UE historical information is not applicable to the cell switching or change, such as when the cell coverage is small, the UE stays in the cell for a short time when the UE moves quickly, or due to signal fluctuations, the UE may switch quickly, continuously and repeatedly between cells.

[0076] Step 102: When the specific switching or change occurs in the cell, the first device performs one of the following:

[0077] Generate terminal history information including a first identifier, where the first identifier is used to indicate that the specific switching or change occurs in the cell;

[0078] Stop recording cell switching or changes;

[0079] Terminal residency information is generated, where the terminal resides in the network node.

[0080] According to step 102, when it is determined in step 101 that the specific switching or change occurs in the cell, the first device will execute: generate terminal history information including a first identifier (an identifier indicating that the specific switching or change occurs in the cell), stop recording the cell switching or change, and generate one of the terminal residence information (information indicating the length of time the terminal resides in the network node), so that when the network performs ping-pong problem analysis, only the UE history information of the cell where non-specific switching or change occurs is used, thereby avoiding the occurrence of misjudgment problems.

[0081] Specifically, in the case of a specific switching or change in a cell, the first device can obtain UE historical information including the first identifier by adding the first identifier to the UE historical information, and the first identifier will be used to distinguish the UE historical information of other scenarios, so that the network does not use the UE historical information with the first identifier added when analyzing the ping-pong switching problem. The first identifier can be understood as the current UE historical information is not used to determine the ping-pong switching, that is, during the process of determining the ping-pong switching, if the network device identifies that the UE historical information includes the first identifier, the UE historical information is not used to determine the ping-pong switching.

[0082] Specifically, in the case of a specific switching or change in a cell, the first device may also stop recording the switching or change in the cell, that is, not generate corresponding UE historical information; or, may also generate UE residence information indicating the length of time the terminal resides in the network node, so that when the network analyzes the ping-pong switching problem, it only uses the UE historical information of other scenarios. Therefore, the problem of the network misjudging the existence of ping-pong switching is effectively solved.

[0083] Of course, in this embodiment, when the first device stops recording the cell switching or change, it can generate terminal residence information to record the duration of the terminal's residence in the network node. When the first device generates terminal history information including the first identifier, it can also generate terminal residence information.

[0084] Among them, if the first device stops recording the cell switching or change when a specific switch or change occurs in the cell, it can also save storage space, avoid updating the UE history information list, and reduce the coverage of the recorded UE history information.

[0085] Among them, if a specific switching or change occurs in the cell, the first device generates UE residence information indicating the length of time the terminal resides in the network node, thereby avoiding the problem that the UE historical information of the PCell and the PSCell cannot be aligned in time.

[0086] It should be noted that the first device can be a terminal or a network device. That is, the historical information processing method of the embodiment of the present application is applicable to both the recording of cell switching or change by the terminal and the recording of cell switching or change by the network device.

[0087] Of course, since the terminal history information including the first identifier is not used to determine the ping-pong handover, the first identifier can also be used to indicate that a specific handover or change occurs in the cell.

[0088] Optionally, in this embodiment, the specific switching or transformation includes at least one of the following:

[0089] Layer 1 triggered switching;

[0090] Layer 2 triggered switching;

[0091] Continuous primary cell switching;

[0092] Continuous primary and secondary cell changes.

[0093] The switching triggered by layer 1 and the switching triggered by layer 2 are the signaling of layer 1 and / or layer 2 that triggers the UE to switch between candidate cells once or multiple times. The switching triggered by layer 1 and / or layer 2 can also be used for SCG, that is, the change of PSCell can be triggered based on layer 1 and / or layer 2.

[0094] The continuous primary cell switching may be MCG continuous PCell cell switching; the continuous primary and secondary cell switching may be SCG continuous PSCell cell switching.

[0095] For example, the first device is a network device (such as a CU or a base station). During a switching triggered by layer 1 and / or layer 2, or a MCG continuous PCell switching, or a SCG continuous PSCell cell change, the UE historical information generated by the CU or the base station will include a first identifier to prompt the network not to use the UE historical information when performing a ping-pong problem analysis. The first device is a UE. During a switching triggered by layer 1 and / or layer 2, or a MCG continuous PCell switching, or a SCG continuous PSCell cell change, the UE historical information generated by the UE will include a first identifier to prompt the network not to use the UE historical information when performing a ping-pong problem analysis.

[0096] Specifically, the first device will add a first identifier to the UE history information of the nodes in the corresponding first-dimensional PCelllist and / or the nodes in the second-dimensional PSCell list according to the specific situation of a specific switch or transformation. The first identifier can be added at the position of the cell identifier or at the position of the residence time. The first identifier can be a reason value and / or an identification bit, etc., in any form.

[0097] Of course, in this embodiment, the specific switching or transformation is not limited to the above implementations and will not be listed one by one here.

[0098] In addition, optionally, in this embodiment, the method further includes:

[0099] In the case that a non-specific handover or change occurs in a cell, the first device generates terminal history information including a second identifier, where the second identifier is used to indicate that a non-specific handover or change occurs in a cell.

[0100] That is to say, when a switch or change occurs in the terminal cell, the first device will determine whether a specific switch or change occurs, so as to perform corresponding processing for different scenarios. For example, the first device determines whether a specific switch or change occurs in the cell. Only when it is determined that the switch that occurs is not triggered by layer 1 and / or layer 2, is not an MCG continuous PCell switch, and is not an SCG continuous PSCell cell change, the first device generates UE historical information for determining ping-pong switching; and if it is determined that a switch triggered by layer 1 and / or layer 2, or an MCG continuous PCell switch, or an SCG continuous PSCell cell change occurs, the first device will not generate UE historical information for determining ping-pong switching, and there is no need to add a new node to the UE historical information list, which saves storage space and does not overwrite the generated UE historical information.

[0101] In the event of a non-specific handover or change in a cell, the terminal historical information is as shown in Table 1, and the residence time will be recorded for the cell (PCell and / or PSCell). That is to say, for a non-specific handover or change in a cell, the first device will still generate UE historical information for subsequent analysis of the ping-pong problem. In addition, the UE historical information also includes a second identifier to distinguish the UE historical information generated when a specific handover or change occurs in the cell. Of course, since the UE historical information generated when a specific handover or change occurs in the cell includes the first identifier, the UE historical information generated when a non-specific handover or change occurs in the cell does not include the second identifier, and can also be distinguished from the UE historical information including the first identifier.

[0102] In addition, optionally, the terminal residency information includes:

[0103] A third identifier, where the third identifier is empty or an identifier of any network node or cell where the terminal resides; and

[0104] The total duration of a terminal staying in multiple consecutive cells under the specific switching or transformation.

[0105] Of course, the terminal residence information can also be recorded in the UE history information list. By adding a node to record the total length of time the terminal resides in these cells when a specific switching or change occurs in the cell, it not only reduces the occupation of the UE history information list by the recorded information when a specific switching or change occurs in the cell, and avoids deleting the old cell record information after the number of UE history information records reaches the upper limit, but also satisfies the alignment of the residence time of the PCell and the corresponding PSCell. For example, as shown in Table 2 below:

[0106] Table 2

[0107]

[0108] That is, in the case of continuous PSCell cell change of SCG, the residence time b is the total residence time of the terminal in multiple cells under continuous PSCell change. The original PSCell cell identification bit corresponding to the residence time b can be empty or the identification of any network node or cell where the terminal resides under continuous PSCell change.

[0109] In this way, when a switching triggered by layer 1 and / or layer 2, or a continuous PCell switching of MCG, or a continuous PSCell cell change of SCG occurs, the first device will add a node to the UE history information list to record the terminal residence information.

[0110] The third identifier may be empty, and the cell identifier or network node identifier is not recorded; or the third identifier is the identifier of any network node or cell where the terminal resides. For example, the third identifier is by default the identifier of the base station, or the identifier of the CU, or the identifier of the DU, or the identifier of the first cell or the last cell.

[0111] Optionally, in this embodiment, the terminal residency information includes:

[0112] an identification of each network node on which the terminal resides; and

[0113] The duration that the terminal stays at each network node.

[0114] That is to say, the terminal residence information can also be similar to the cell-level time record of UE historical information, and the network node-level residence duration can be performed so that it can be known and used when needed later (such as inter-MN / SN / CU / DU switching or PSCell cell change).

[0115] Optionally, the network node includes at least one of the following:

[0116] Base station; Centralized unit; Distributed unit.

[0117] That is, the terminal residency information may be recorded at one or more of the base station level, CU level and DU level to meet different requirements.

[0118] For example, when a switching triggered by layer 1 and / or layer 2, or a continuous PCell switching of MCG, or a continuous PSCell change of SCG occurs, the first device will add a corresponding number of nodes to the UE history information list based on the number of network nodes involved to record the residence time of the terminal at each network node. Assuming that the default network node is a base station, and a specific switching or change involves 4 cells under two base stations, the residence time of each cell under the same base station is not recorded, but the residence time of the two base stations is recorded separately. That is to say, when a cell switching occurs within the base station, the residence time of the cell is not recorded. When the cell is switched or changed to a cell of a different base station, a node is added to the UE history information list to record the residence time of the base station. The same applies when the network node is CU or DU.

[0119] Of course, the implementation of the network node is not limited to the base station, CU or DU, which will not be listed one by one here.

[0120] In this embodiment, the network node may be a MN node or a SN node.

[0121] Optionally, the terminal history information includes at least one of the following:

[0122] Terminal historical information of the primary cell; terminal historical information of the primary and secondary cells.

[0123] That is to say, in this embodiment, the terminal history information generated by the first device can record relevant information of the PCell and / or PSCell for a specific scenario of cell switching or change, so as to be applicable to dual connectivity.

[0124] Optionally, the terminal residency information includes at least one of the following:

[0125] Terminal residency information of the primary cell; Terminal residency information of the primary and secondary cells.

[0126] That is, similar to the UE historical information, the terminal residence information generated by the first device can also record relevant information of the PCell and / or PSCell for a specific scenario of cell switching or change, so as to be applicable to dual connectivity.

[0127] In summary, according to the method of the embodiment of the present application, when the first device faces a situation where a specific switch or change occurs in a cell, it will execute the following: generate terminal history information including a first identifier (an identifier indicating that the terminal history information is not used to determine ping-pong switching), stop recording cell switching or changes, and generate one or more of the terminal residence information (information indicating the length of time the terminal resides in a network node), so that when the network performs ping-pong problem analysis, only the UE history information of non-specific switches or changes in the cell is used, thereby avoiding the occurrence of misjudgment problems.

[0128] like Figure 2 As shown, the embodiment of the present application further provides a historical information processing device, including: a memory 220, a transceiver 210, and a processor 200: the memory 220 is used to store program instructions; the transceiver 210 is used to send and receive data under the control of the processor 200; the processor 200 is used to read the program instructions in the memory 220 and perform the following operations:

[0136] Layer 2 triggered switching;

[0137] Continuous primary cell switching;

[0138] Continuous primary and secondary cell changes.

[0139] Optionally, the processor is further configured to perform the following operations:

[0140] In the case that a non-specific handover or change occurs in a cell, the first device generates terminal history information including a second identifier, where the second identifier is used to indicate that a non-specific handover or change occurs in a cell.

[0142] A third identifier, where the third identifier is empty or an identifier of any network node or cell where the terminal resides; and
