[0075] As shown in FIG1 , a communication system 100 includes a terminal 101 and a network device 102 , wherein the network device includes at least one of the following: an access network device and a core network device.

[0076] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0078] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0079] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0080] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0081] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0082] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0083] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0084] In some embodiments, the terminal may perform measurement operations, record measurement results, and further send the measurement results to a network device.

[0085] For example, scenarios for recording measurement results include at least one of the following: Minimization Drive Test (MDT) and Self-Organizing Network (SON).

[0086] In some embodiments, the measurement results recorded by the terminal only include layer 3 (Layer 3, L3) measurement results. However, in some scenarios, the L3 measurement results are insufficient to assist the network device.

[0087] For example, in a Layer 1 or Layer 2 triggered mobility (L1 / L2-Triggered Mobility, LTM) scenario, the network device can configure LTM configuration information for the terminal. The LTM configuration information includes candidate cells (which can be a single cell or a cell group consisting of multiple cells) and may also include relevant information used for communication in the candidate cells.

[0088] The network device can subsequently perform LTM cell switching on the terminal. For example, the network device can instruct the terminal to change the cell through layer 1 (for example, through downlink control information (DCI)) or layer 2 (for example, through a media access control layer control element (MAC CE)), for example, instruct the terminal to change the cell from candidate cell #1 to candidate cell #2.

[0089] Since the relevant information used for communication in the candidate cell is pre-configured to the terminal by the network device through LTM configuration, after the terminal switches to candidate cell #2, the network device does not need to configure the relevant information used for communication in candidate cell #2 for the terminal, which is conducive to the terminal completing cell switching and communication as soon as possible.

[0090] L3-triggered mobility cell switching, such as traditional handover (HO) and conditional handover (CHO), is triggered by RRC signaling. Compared with LTM cell switching, this takes longer and is not conducive to the terminal completing cell switching and communication as quickly as possible.

[0091] However, the traditional measurement results sent by the terminal to the network device are mainly used to assist the network device in performing L3 triggered mobility, but are not used to assist the network device in performing LTM. Therefore, it is necessary to improve the measurement results sent by the terminal to the network device.

[0092] FIG2 is an interactive schematic diagram illustrating an information recording method according to an embodiment of the present disclosure.

[0093] As shown in FIG2 , the information recording method may include the following steps:

[0094] In step S201 , the terminal records Layer 1 or Layer 2 Triggered Mobility (L1 / L2-Triggered Mobility, LTM) related measurement results.

[0095] In step S202, the terminal sends the LTM-related measurement results to the network device.

[0096] In the embodiments of the present disclosure, since the measurement results recorded by the terminal are LTM-related measurement results, compared with the traditional measurement results sent by the terminal to the network device to assist the network device in performing L3-triggered mobility, the LTM-related measurement results can assist the network device in performing LTM, which is beneficial to ensure that the network device can determine whether to perform LTM in a timely and accurate manner based on the LTM-related measurement results reported by the terminal.

[0097] In some embodiments, the LTM-related measurement results include at least one of the following: measurement results of layer 1; measurement results of layer 3.

[0098] In some embodiments, the terminal can measure the signal in the beam of the network device, for example, it can measure the synchronization broadcast signal block (SS (Synchronization Signal) and PBCH (Physical downlink Broadcast Channel) Block, SSB) in the beam. Of course, the measured signal is not limited to measuring SSB, and other signals can also be measured, such as channel state information (Channel State Information Reference Signal, CSI-RS), etc. The embodiments of the present disclosure are not limited to this.

[0099] In some embodiments, the LTM-related measurement results may include measurement results corresponding to one or more SSBs of the candidate cell of the LTM configuration information.

[0100] For example, the signal may first pass through a layer 1 (Layer 1, L1) filter to obtain a measurement result of layer 1. The measurement result of layer 1 may then be input into a layer 3 filter to obtain a filtering result of layer 3.

[0101] For example, the relevant parameters of the layer 1 filter may be determined based on the UE implementation specifics.

[0102] For example, relevant parameters of the layer 3 filter may be determined based on Radio Resource Control (RRC) configures parameters.

[0103] For example, the LTM-related measurement results may include only the measurement results of L1; for example, the LTM-related measurement results may include the measurement results of L1 and the measurement results of L3. For example, the LTM-related measurement results may include the measurement results of L3.

[0104] In some embodiments, when the LTM-related measurement results only include L1 measurement results, the LTM-related measurement results can assist the network device in deciding at least one of the following: whether to perform LTM, how to perform LTM (for example, on which time-frequency resources).

[0105] In some embodiments, when the LTM-related measurement results include L1 measurement results and L3 measurement results, the LTM-related measurement results can assist the network device in deciding at least one of the following: whether to perform LTM and switching based on L3 measurement results (for example, traditional HO, CHO, etc.), whether to perform LTM or switching based on L3 measurement results (for example, traditional HO, CHO, etc.), how to perform LTM (for example, on which time-frequency resources), and how to perform switching based on L3 measurement results (for example, on which time-frequency resources).

[0106] In some embodiments, when the LTM-related measurement results may only include L3 measurement results, the LTM-related measurement results may assist the network device in deciding at least one of the following: whether it is reasonable to perform switching based on the L3 measurement results, and whether LTM is still required.

[0107] As for whether the LTM-related measurement results specifically include L1 measurement results, or L3 measurement results, or both L1 measurement results and L3 measurement results, this may be instructed by the network device or agreed upon by the protocol.

[0108] In some embodiments, the measurement result of layer 1 and the measurement result of layer 3 may be measurement results for the same cell (for example, the measurement result of layer 1 is the layer 1 measurement result for cell #1, and the measurement result of layer 3 is the layer 3 measurement result for cell #1).

[0109] In some embodiments, the measurement results of layer 1 and layer 3 may be measurement results for different cells (for example, the measurement results of layer 1 are the layer 1 measurement results for cell 1, and the measurement results of layer 3 are the layer 3 measurement results for cell #2).

[0110] As for whether the layer 1 measurement result and the layer 3 measurement result are measurement results for the same cell or measurement results for different cells, the terminal can determine based on network device instructions or protocol agreements, and this disclosure does not limit this.

[0111] In some embodiments, since the measurement results of layer 1 include physical layer measurement results, when the terminal sends LTM-related measurement results to the network device through RRC signaling, the terminal can first perform internal interaction, for example, obtain the measurement results of layer 1 from the physical layer through the RRC layer, and then send the LTM-related measurement results to the network device through RRC signaling.

[0112] In some embodiments, the LTM-related measurement results include at least one of the following:

[0113] LTM-related measurement results of the serving cell of the terminal;

[0114] LTM-related measurement results of the source cell of the terminal (for example, the cell where the terminal is located before cell handover);

[0115] LTM-related measurement results of the target cell of the terminal (for example, the cell to which the terminal needs to switch to when performing cell switching);

[0116] LTM-related measurement results of neighboring cells of the terminal;

[0117] LTM-related measurement results of the candidate cells in the LTM configuration information.

[0118] Take the LTM-related measurement results including the LTM-related measurement results of the candidate cells in the LTM configuration information as an example.

[0119] In some embodiments, when recording LTM-related measurement results, the terminal may mark the association between the measurement results and the cell, and may also mark the cell type. For example, the LTM-related measurement results recorded by the terminal include measurement result #1. Measurement result #1 is the measurement result for cell #1. Cell #1 may be a candidate cell in the LTM configuration information. The terminal may mark cell #1 as a candidate cell in the LTM configuration information. Subsequently, when the LTM-related measurement results are subsequently sent to a network device, the network device can also determine that measurement result #1 is the measurement result for cell #1 and that cell #1 is a candidate cell in the LTM configuration information.

[0120] In some embodiments, when recording measurement results, the terminal may record LTM-related measurement results of the candidate cell in the LTM configuration information separately from LTM-related measurement results of other cells. For example, the terminal may record the LTM-related measurement results of the candidate cell in the LTM configuration information in a dedicated list, and then subsequently send the LTM-related measurement results to the network device. The network device may determine that the measurement results in the dedicated list are the LTM-related measurement results of the candidate cell in the LTM configuration information.

[0121] In some embodiments, recording the LTM-related measurement results includes: recording the LTM-related measurement results into a report variable, wherein the report variable includes at least one of the following: a connection establishment failure (CEF) report variable; a radio link failure (RLF) report variable; and a success handover report (SHR) variable.

[0122] When recording the LTM-related measurement results, the terminal may record the LTM-related measurement results into a report variable, and then send the content in the report variable to the network device, thereby sending the LTM-related measurement results to the network device.

[0123] Of course, before sending the LTM-related measurement results to the network device, the terminal is not limited to recording the LTM-related measurement results by reporting variables, and may also record the LTM-related measurement results by other means, which is not limited by the present disclosure.

[0124] For example, the CEF report variables may include at least one of the following: VarConnEstFailReport-r16, VarConnEstFailReportList-r17, VarConnEstFailReportList-r18.

[0125] For example, the RLF report variable may include at least one of the following: rlf-Report-r16, rlf-Report-r17, and rlf-Report-r18. When the terminal records the LTM-related measurement result in the RLF report variable, the LTM-related measurement result may include an LTM-related measurement result for RLF or an LTM-related measurement result for HO failure.

[0126] For example, the SHR variable may include at least one of the following: VarSuccessHO-Report-r17, VarSuccessHO-Report-r18.

[0127] In some embodiments, recording the LTM-related measurement result includes: determining that a first condition is satisfied, and recording the LTM-related measurement result, wherein the first condition includes at least one of the following:

[0128] The terminal is configured with LTM configuration information;

[0129] The first cell belongs to the candidate cell in the LTM configuration information, wherein the first cell includes at least one of the following: a serving cell of the terminal, a source cell of the terminal, a target cell of the terminal, and a neighboring cell of the terminal;

[0130] The LTM-related measurement results are triggered by LTM cell switching.

[0131] In some embodiments, the terminal determines that RLF occurs in cell #1, and cell #1 may include at least one of the following: the serving cell of the terminal, the source cell of the terminal, the target cell of the terminal, and the neighboring cell of the terminal. The terminal may record the LTM-related measurement results of cell #1 in a report reporting variable.

[0132] In some embodiments, if a terminal determines that an RLF has occurred in cell #1 and the terminal is configured with LTM configuration information, the terminal may record LTM-related measurement results of cell #1 in a report variable. Cell #1 may include at least one of the following: a serving cell of the terminal, a source cell of the terminal, a target cell of the terminal, or a neighboring cell of the terminal.

[0133] In some embodiments, the terminal determines that CEF occurs in cell #1, and cell #1 may include at least one of the following: the serving cell of the terminal, the source cell of the terminal, the target cell of the terminal, and the neighboring cell of the terminal. The terminal may record the LTM-related measurement results of cell #1 in a report reporting variable.

[0134] In some embodiments, if a terminal determines that CEF occurs in cell #1 and the terminal is configured with LTM configuration information, the terminal may record LTM-related measurement results of cell #1 in a report variable. Cell #1 may include at least one of the following: a serving cell of the terminal, a source cell of the terminal, a target cell of the terminal, and a neighboring cell of the terminal.

[0135] In some embodiments, the terminal determines LTM-related measurement results, which are triggered by LTM cell switching (eg, LTM premature switching, LTM late switching, LTM switching failure, etc.), and the terminal may record the LTM-related measurement results in a report variable.

[0136] It should be noted that the triggering conditions for the terminal to record LTM-related measurement results are not limited to the above-mentioned cases. For example, the terminal may also record LTM-related measurement results into the report variable when the SHR triggering recording conditions are met.

[0137] In some embodiments, the terminal receives request information sent by the network device, wherein the request information is used to request the terminal to send the LTM-related measurement result to the network device.

[0138] For example, the terminal may send LTM-related measurement results to the network device only after receiving a request message sent by the network device. The request message may reuse a traditional request message (e.g., a report request), or may be a newly defined request message specifically for requesting the terminal to send LTM-related measurement results.

[0139] It should be noted that, in some embodiments, the terminal may send LTM-related measurement results to the network device not based on the request information of the network device. For example, the terminal may record the time t1 for determining the LTM-related measurement results. When no request information from the network device is received within the time range from t1 to T1, the terminal may automatically send the LTM-related measurement results to the network device (for example, on pre-configured resources). This helps to avoid the terminal's LTM-related measurement results being deleted due to being stored for too long, resulting in waste of measurement operation overhead.

[0140] The following describes, through several embodiments, a case where the LTM-related measurement results include the L1 measurement results.

[0141] In some embodiments, in response to the occurrence of RLF, the terminal may record a cell-associated L1 measurement result into a reporting variable, where the cell is an LTM candidate cell, including the PCell where the RLF occurs and at least one of the neighboring cells.

[0142] In some embodiments, in response to the occurrence of RLF, if the terminal has an available LTM configuration, the L1 measurement results associated with the cell may be recorded in a reporting variable, including at least one of the PCell where the RLF occurs and the neighboring cells.

[0143] In some embodiments, in response to meeting the SHR trigger recording condition, the terminal may record the L1 measurement result associated with the cell into the reporting variable, where the cell is an LTM candidate cell, including at least one of the handover source cell, the target cell, and the neighboring cell.

[0144] In some embodiments, in response to the occurrence of CEF, the terminal may record the L1 measurement result associated with the cell into a reporting variable, where the cell is an LTM candidate cell including at least one of the PCell where the CEF occurs and a neighboring cell.

[0145] In some embodiments, in response to the occurrence of CEF, if the terminal has an available LTM configuration, the L1 measurement result associated with the cell may be recorded in a reporting variable, including at least one of the PCell where the CEF occurs and the neighboring cell.

[0146] In some embodiments, the terminal may send capability indication information to the network device, where the capability indication information is used to indicate at least one of the following:

[0147] Whether the terminal supports recording LTM-related measurement results;

[0148] Whether the terminal supports sending the LTM-related measurement results to a network device.

[0149] In some embodiments, the terminal informs the network device of its support for recording and sending LTM-related measurement results to the network device, so that the network device can perform appropriate operations later and avoid wasting resources.

[0150] For example, if the terminal supports recording LTM-related measurement results and supports sending the LTM-related measurement results to the network device, then the capability information sent by the terminal to the network device may indicate that the terminal supports recording LTM-related measurement results and supports sending the LTM-related measurement results to the network device.

[0151] In this case, when the network device needs the LTM-related measurement result, it may choose to send a request message to the terminal to request the terminal to send the LTM-related measurement result to the network device.

[0152] For example, if the terminal supports recording LTM-related measurement results but does not support sending the LTM-related measurement results to the network device, the capability information sent by the terminal to the network device may indicate that the terminal supports recording LTM-related measurement results but does not support sending the LTM-related measurement results to the network device.

[0153] In this case, when the network device needs LTM-related measurement results, it can choose to send a request message to other devices that can communicate with the terminal to request other devices to obtain LTM-related measurement results from the terminal, and then obtain the LTM-related measurement results recorded by the terminal from other devices.

[0154] For example, if the terminal does not support recording LTM-related measurement results but supports sending the LTM-related measurement results to the network device, then the capability information sent by the terminal to the network device may indicate that the terminal does not support recording LTM-related measurement results but supports sending the LTM-related measurement results to the network device.

[0155] In this case, since the terminal does not record the LTM-related measurement results, the network device does not need to try to obtain the LTM-related measurement results recorded by the terminal.

[0156] In some embodiments, the terminal may further send availability indication information to the network device, where the availability indication information is used to indicate that available LTM-related measurement results are stored in the terminal.

[0157] In some embodiments, the availability indication information may reuse traditional availability indication information; or may be newly defined availability indication information, which may be specifically used to indicate that available LTM-related measurement results are stored in the terminal.

[0158] In some embodiments, the LTM-related measurement results may be included in a report sent by the terminal to the network device.

[0159] Among them, the report containing LTM-related measurement results can be a traditional report, such as a traditional SON report (such as a traditional RLF report, a traditional SHR, a traditional CEF report, etc.), a traditional MDT report, etc.; it can also be a newly defined report, such as a newly defined SON report (such as a newly defined RLF report, a newly defined SHR, a newly defined CEF report, etc.), such as a newly defined MDT report.

[0160] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 and S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.

[0161] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0162] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0163] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.
