[0050] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0051] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0052] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0053] For ease of understanding, some contents involved in the embodiments of the present disclosure are described as follows:

[0054] 1) Introduction to UE historical information

[0055] UE historical information is divided into UE historical information recorded by the network side and UE historical information recorded by the UE. Both contain information such as the cell where the UE resides / accesses and the length of time it resides, and are used to solve the problem of ping-pong switching.

[0056] The UE history information maintained by the network includes the cell identifiers of each PCell cell and the corresponding PSCell, as well as the corresponding access time information, for each UE in the connected state. During a handover, this information is sent to the target base station via a handover request message and is subsequently maintained by the target base station. Because the base station is unaware of the terminal's idle state, the UE history information maintained by the network does not include information about UEs in the idle state.

[0057] The network records UE historical information for distributed base stations and integrated base stations. For distributed base stations, the central unit (CU) records UE historical information. Each time a distributed unit (DU) notifies the CU of a cell change via an interface, the CU records the UE historical information. For integrated base stations, the base station is responsible for recording UE historical information.

[0058] The UE history information maintained by the terminal includes information records of the PCell and the corresponding PSCell in both idle and connected states. This information requires terminal capability support and is obtained by the network through dedicated signaling messages.

[0059] 2) Multi-Rate Dual Connectivity (MR-DC) Network Architecture

[0060] In a multi-connectivity architecture, a UE may connect to a Master Node (MN) and one or more Secondary Nodes (SN), performing signaling and / or data exchanges with these network nodes. Both the MN and SN nodes can be LTE / e-LTE / NR nodes. When there is one MN and one SN, it is called Dual Connection (DC).

[0061] When a 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 (RATs). For example, when the MN is an LTE node and the SN is an NR node, it is (NG)EN-DC dual connectivity; when the MN is an NR node and the SN is an LTE node, it is NE-DC dual connectivity; when both the MN and the SN are NR nodes, it is NR-NR-DC.

[0062] SCG is a serving cell group under the SN node under the MR-DC, including a PSCell and one or more possible secondary cells (Scell).

[0063] For the UE history information maintained by the base station, the SN node is responsible for collecting the UE history information related to the PSCell and sending it to the MN through the XN / X2 interface message. The MN generates the UE history information containing the PCell and PSCell information according to the corresponding time information, as shown in Table 1 below.

[0064] Table 1

[0065] In the UE's historical information, the PCell and PSCell are associated and correspond in time. In the table above, the UE accessed PCell A for time A. It then established dual connectivity with PSCell a for time a. It then deleted the dual connectivity and maintained single connectivity for time b. It then established dual connectivity with PSCell c for time c. The PSCell then switched from PSCell c to PSCell d for time d. It then deleted the dual connectivity and maintained single connectivity for time e. The PCell then switched from PCell A to PCell B, maintaining single connectivity throughout.

[0066] The UE history information shown in the table above is a two-dimensional structure. The first dimension, the PCell list, contains up to 16 nodes, recording information for 16 cells. The second dimension, the PSCell list corresponding to each PCell node, contains up to 8 nodes, recording information for 8 cells. If the recorded cell information limit is reached, the oldest cell record is deleted and replaced with the current record, which always contains cell information from the most recent time period.

[0067] The UE history information maintained by the terminal is also a two-dimensional structure, with similar structure and content to the above table. However, the PCell list in the two-dimensional structure and the PSCell list corresponding to each PCell both contain a maximum of 16 nodes, that is, they record information about 16 cells. When the upper limit is reached, the same process is used as above.

[0068] 3) Enhanced mobility

[0069] The handover triggered by Layer 1 (Layer 1) and Layer 2 (Layer 2) is a handover 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 perform one or multiple consecutive handovers between candidate cells. Unlike the traditional handover based on Radio Resource Management (RRM) measurement configuration and reporting information, sending a Layer 3 handover command to trigger handover can achieve continuous, repeated and fast handover between multiple cells. The handover 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.

[0070] 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.

[0071] MCG continuous PCell cell switching is similar to SCG continuous PSCell cell switching. 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. It then 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.

[0072] 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.

[0073] The present disclosure provides a method and apparatus for processing historical information. The method and apparatus are based on the same patent application concept. Since the method and apparatus solve similar problems, the implementation of the apparatus and method can refer to each other, and the repetitive parts will not be repeated.

[0074] As shown in FIG1 , a method for processing historical information provided by an embodiment of the present disclosure includes:

[0075] Step 101: The first device determines whether a specific handover or change occurs in a cell.

[0076] In this step, the first device determines whether a specific handover or change occurs when a handover or change occurs in the terminal cell, so that corresponding processing can be performed for the scenario in which the handover or change occurs. Among them, the specific handover or change of the cell refers to a scenario in which the ping-pong handover judgment based on the UE historical information is not applicable to the cell handover or change, such as when the cell coverage is small, the UE's residence time in the cell is very short when it moves quickly, or due to signal fluctuations, the UE may switch between cells quickly, continuously and repeatedly.

[0077] Step 102: When the specific handover or change occurs in the cell, the first device performs one of the following:

[0078] Generate terminal history information including a first identifier, where the first identifier is used to indicate that the specific handover or change occurs in the cell;

[0079] Stop recording cell handovers or changes;

[0080] Terminal residency information is generated, where the terminal resides in the network node.

[0081] 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 historical 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 historical information of non-specific switching or change of the cell is used, thereby avoiding the occurrence of misjudgment problems.

[0082] Specifically, in the event of a specific handover or change in a cell, the first device can obtain UE historical information including the first identifier by adding a first identifier to the UE historical information. The first identifier will be used to distinguish UE historical information in other scenarios, so that the network does not use the UE historical information with the first identifier added when analyzing ping-pong handover problems. The first identifier can be understood as indicating that the current UE historical information is not used to determine ping-pong handovers. That is, during the process of determining ping-pong handovers, if the network device identifies that the UE historical information includes the first identifier, the UE historical information will not be used to determine ping-pong handovers.

[0083] Specifically, when a specific cell handover or change occurs, the first device can stop recording the cell handover or change, that is, not generate corresponding UE historical information; or it can generate UE residency information indicating the length of time the terminal resided on the network node. In this way, when the network analyzes ping-pong handover issues, it only uses UE historical information from other scenarios. This effectively solves the problem of the network mistakenly judging that a handover has occurred during a ping-pong handover.

[0084] Of course, in this embodiment, when the first device stops recording the cell switching or change, it can generate terminal residency information to record the length of time the terminal resides on the network node. When the first device generates terminal history information including the first identifier, it can also generate terminal residency information.

[0085] Among them, if a specific switch or change occurs in the cell, the first device stops recording the cell switch or change, which can also save storage space, avoid updating the UE history information list, and reduce the coverage of the recorded UE history information.

[0086] 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 of UE historical information of PCell and PSCell not being aligned in time.

[0087] 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 disclosure is applicable to both the recording of cell switching or change by a terminal and the recording of cell switching or change by a network device.

[0088] Of course, since the terminal history information including the first identifier is not used to determine ping-pong handover, the first identifier can also be used to indicate that a specific handover or change occurs in a cell.

[0089] In some embodiments, the specific switching or transformation includes at least one of the following:

[0090] Layer 1 triggered switching;

[0091] Layer 2 triggered switching;

[0092] Continuous primary cell switching;

[0093] Continuous primary and secondary cell changes.

[0094] Layer 1 triggered handover and layer 2 triggered handover are handovers triggered by layer 1 and / or layer 2 signaling, causing the UE to perform one or multiple consecutive handovers between candidate cells. Layer 1 and / or layer 2 triggered handovers can also be used for SCGs, i.e., PSCell changes can be triggered based on layer 1 and / or layer 2.

[0095] Among them, the continuous primary cell switching can be MCG continuous PCell cell switching; the continuous primary and secondary cell switching can be SCG continuous PSCell cell switching 。

[0096] For example, the first device is a network device (such as a CU or a base station). During a handover triggered by layer 1 and / or layer 2, or a continuous PCell handover of MCG, or a continuous PSCell cell change of SCG, 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 handover triggered by layer 1 and / or layer 2, or a continuous PCell handover of MCG, or a continuous PSCell cell change of SCG, 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.

[0097] Specifically, the first device will add a first identifier to the UE history information of the nodes in the corresponding first-dimensional PCell list 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 cause value and / or an identification bit, etc., and the form is not limited.

[0098] Of course, in this embodiment, specific switching or transformation is not limited to the above implementations and will not be listed here one by one.

[0099] In addition, in some embodiments, the method further comprises:

[0100] 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 the cell.

[0101] That is to say, when a handover or change occurs in the terminal cell, the first device will determine whether a specific handover or change occurs, and thus perform corresponding processing for different scenarios. For example, the first device determines whether a specific handover or change occurs in the cell. Only when it is determined that the handover is not triggered by layer 1 and / or layer 2, is not an MCG continuous PCell handover, and is not an SCG continuous PSCell cell change, the first device will generate UE historical information for determining ping-pong handover; and if it is determined that a handover is triggered by layer 1 and / or layer 2, or an MCG continuous PCell handover, or an SCG continuous PSCell cell change occurs, the first device will not generate UE historical information for determining ping-pong handover, 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 already generated UE historical information.

[0102] In the case of non-specific switching or transformation of 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 non-specific switching or transformation of 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 switching or transformation occurs in the cell. Of course, since the UE historical information generated when a specific switching or transformation occurs in the cell includes the first identifier, the UE historical information generated when a non-specific switching or transformation occurs in the cell does not include the second identifier, and can also be distinguished from the UE historical information including the first identifier.

[0103] Furthermore, in some embodiments, the terminal residency information includes:

[0104] A third identifier, where the third identifier is empty or an identifier of any network node or cell where the terminal resides; and

[0105] The total duration that the terminal resides in multiple consecutive cells during the specific handover or transformation.

[0106] Of course, the terminal residency information can also be recorded in the UE history information list. By adding a new node to record the total length of time the terminal resides in these cells when a specific handover 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 handover or change occurs in the cell, but also avoids deleting the old cell record information after the number of UE history information records reaches the upper limit, and also satisfies the alignment of the residency time of the PCell and the corresponding PSCell. For example, as shown in Table 2 below:

[0107] Table 2

[0108] That is, in the case of continuous PSCell cell changes of SCG, the residence time b is the total residence time of the terminal in multiple cells under continuous PSCell changes. 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 changes.

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

[0110] The third identifier can be empty, meaning no cell identifier or network node identifier is recorded; or the third identifier is the identifier of any network node or cell where the terminal resides. For example, the third identifier is set by default to be the identifier of the base station, the identifier of the CU, the identifier of the DU, or the identifier of the first or last cell.

[0111] In some embodiments, the terminal residency information includes:

[0112] the identity 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] In some embodiments, the network node includes at least one of the following:

[0116] Base station; centralized unit; distributed unit.

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

[0118] For example, when a handover triggered by layer 1 and / or layer 2, or a continuous PCell handover of MCG, or a continuous PSCell transformation 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 handover or transformation 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 handover occurs within a base station, the residence time of the cell is not recorded. When the cell is switched or transformed into a cell of a different base station, a new 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, and they are not listed one by one here.

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

[0121] In some embodiments, 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, 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] In some embodiments, 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 residency 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 invention, when the first device faces the situation of specific switching or changing of the cell, it will execute: generate terminal history information including a first identifier (an identifier indicating that the terminal history information is not used to judge ping-pong switching), stop recording the cell switching or changing, and generate one or more 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 non-specific switching or changing of the cell is used, thereby avoiding the occurrence of misjudgment problems.
