Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and related devices. Background Art

[0002] The 3rd Generation Partnership Project (3GPP) Release 17 (R17) introduced the new radio (NR) multicast / broadcast service (MBS) feature, which supports multicast sessions and broadcast sessions. For terminal devices that support MBS and are in a connected state, when multicast broadcast services are prioritized, the terminal device can move to the NR cell that supports MBS by means of reconstruction to (continue to) receive broadcast information (such as broadcast programs), but reconstruction will affect unicast services (such as data or voice services), causing unicast services to freeze. Based on this, it is currently proposed that the terminal device reports the MBS frequency point of interest to the access network device instead of reconstruction, so as to prompt the access network device to try to pull the terminal device to the NR cell that supports MBS in subsequent switching, which can reduce the impact on unicast services. However, at present, only after the terminal device resides in the NR cell and receives the SIB21 broadcast by the NR cell, can the terminal device report the MBS frequency point of interest to the access network device. If the terminal device resides in an LTE cell, or the NR cell where it resides does not broadcast SIB21, the terminal device will not be able to report the MBS frequency point that the terminal device is interested in, and therefore network traction cannot be achieved. Based on this, how to ensure the user's demand for watching broadcast programs without affecting the unicast service has become an urgent problem to be solved. Summary of the invention

[0003] The present application provides a communication method and related devices, which can ensure the user's demand for watching broadcast programs without affecting the unicast service, and is conducive to improving the user experience.

[0004] In a first aspect, the present application provides a communication method, which is executed by a terminal device, and the terminal device can be the terminal device itself, or a module or chip in the terminal device. In the method, the terminal device receives first measurement configuration information from a first cell; the first measurement configuration information includes at least one measurement frequency and at least one measurement event; the at least one measurement frequency includes a first measurement frequency, the first measurement frequency is a frequency supporting a multicast broadcast service MBS, the first measurement frequency is associated with a first measurement event, the first measurement event is included in the at least one measurement event, and the first measurement event corresponds to a first evaluation threshold value and a first evaluation duration; when the reporting condition of the first measurement event is determined to be met according to the measurement result of the cell on the first measurement frequency, the second evaluation threshold value and the second evaluation duration, the terminal device sends a measurement report of the first measurement event; the second evaluation threshold value is less than the first evaluation threshold value, and the second evaluation duration is less than or equal to the first evaluation duration; or, the second evaluation threshold value is equal to the first evaluation threshold value, and the second evaluation duration is less than the first evaluation duration; the terminal device receives a switching command, and the switching command is used to instruct the terminal device to switch to the cell on the first measurement frequency. Here, the first cell is the current serving cell.

[0005] The embodiment of the present application promotes the priority reporting of measurement events of cells supporting MBS frequency points, so that the access network device can drive the terminal device to switch / move to the cell supporting MBS through a switching command, and can also ensure the user's demand for watching broadcast programs without affecting the unicast service, which is conducive to improving the user experience. Specifically, the promotion method includes reducing the evaluation threshold value of the MBS cell and / or shortening the evaluation time of the MBS cell.

[0006] In a possible design, the at least one measurement frequency further includes a second measurement frequency, where the second measurement frequency is a frequency that does not support MBS, the second measurement frequency is associated with a second measurement event, the second measurement event is included in the at least one measurement event, and the second measurement event corresponds to a third evaluation threshold and a third evaluation duration;

[0007] The method further comprises:

[0008] When it is determined that the reporting condition of the second measurement event is met according to the measurement result of the cell on the second measurement frequency, the fourth evaluation threshold value, and the fourth evaluation duration, sending a measurement report of the second measurement event;

[0009] The fourth evaluation threshold value is greater than the third evaluation threshold value, and the fourth evaluation duration is greater than or equal to the third evaluation duration; or, the fourth evaluation threshold value is equal to the third evaluation threshold value, and the fourth evaluation duration is greater than the third evaluation duration.

[0010] In this implementation, the promotion method may also include increasing the evaluation threshold of the non-MBS cell and / or extending the evaluation time of the non-MBS cell. The implementation method is diverse and has high applicability.

[0011] In one possible design, the method further includes:

[0012] When the difference between the measurement result of the cell at the first measurement frequency point and the measurement result of the first cell within the second evaluation time period is greater than or equal to the second evaluation threshold value, it is determined that the reporting condition of the first measurement event is met.

[0013] In this implementation mode, when the first cell is an NR cell (ie, the terminal device resides in the NR cell, or the service cell is called the NR cell), the first measurement event may be an A3 event, indicating that the quality of the neighboring cell is higher than the quality of the service cell.

[0014] In one possible design, the method further includes:

[0015] When the measurement results of the cells at the first measurement frequency point within the second evaluation time period are all greater than or equal to the second evaluation threshold value, it is determined that the reporting condition of the first measurement event is met.

[0019] In this implementation mode, when the first cell is an NR cell (that is, the terminal device resides in the NR cell, or the service cell is called the NR cell), the first measurement event may be an A5 event, indicating that the quality of the service cell is lower than a certain threshold and the quality of the neighboring cell is higher than a certain threshold; when the first cell is an LTE cell (that is, the terminal device resides in the LTE cell, or the service cell is called the LTE cell), the first measurement event may be a B2 event, indicating that the quality of the service cell (that is, the LTE cell) is lower than a certain threshold and the quality of the neighboring cell of the other system (that is, the NR system) is higher than a certain threshold.

[0025] The measurement report of the third measurement event is used to trigger the sending of the first measurement configuration information; the sixth evaluation threshold value is greater than the fifth evaluation threshold value, and the sixth evaluation duration is less than or equal to the fifth evaluation duration; or, the sixth evaluation threshold value is equal to the fifth evaluation threshold value, and the sixth evaluation duration is less than the fifth evaluation duration.

[0026] In this implementation, when the terminal device resides in an LTE cell (or the serving cell is an LTE cell), if the network does not configure a B measurement event (such as a B1 event, a B2 event, etc.), the access network device may further configure a third measurement event, and by promoting reporting of the third measurement event, prompt the network to configure a B measurement event. The method of promoting reporting of the third measurement event includes, but is not limited to, increasing the evaluation threshold of the third measurement event, and / or shortening the evaluation duration of the third measurement event, etc.

[0027] In one possible design, the method further includes:

[0029] In this implementation, the third measurement event may be an A2 event, which indicates that the signal quality of the serving cell is lower than a certain threshold.

[0065] The specific embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.

[0066] The terms "first" and "second" and the like in the specification, claims and drawings of this application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0067] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0068] In the present application, "at least one (item)" means one or more, "more than one" means two or more, "at least two (items)" means two or three and more than three, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0069] In order to better understand the embodiments of the present application, the system architecture involved in the embodiments of the present application is first introduced below:

[0070] See also Figure 1 , Figure 1 Schematic diagram of the architecture of the communication system used in the embodiment of the present application. Figure 1 As shown, the communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. Optionally, the communication system 1000 may also include the Internet 300. The RAN 100 includes at least one RAN node (e.g. Figure 1 110a and 110b, collectively referred to as 110) and at least one terminal (such as Figure 1 RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment ( Figure 1 The terminal 120 is connected to the RAN node 110 in a wireless manner. The RAN node 110 is connected to the core network 200 in a wireless or wired manner. The core network device in the core network 200 and the RAN node 110 in the RAN 100 may be different physical devices, or may be the same physical device that integrates the core network logical function and the radio access network logical function.

[0071] RAN 100 may be a cellular system related to the third generation partnership project (3GPP), for example, a 4G, 5G mobile communication system, or a future evolution system (for example, a 6G mobile communication system). RAN 100 may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN), or a wireless fidelity (wireless fidelity, WiFi) system. RAN 100 may also be a communication system that integrates two or more of the above systems.

[0072] The RAN node 110, which may also be sometimes referred to as an access network device, a RAN entity or an access node, constitutes a part of the communication system to help the terminal achieve wireless access. The multiple RAN nodes 110 in the communication system 1000 may be nodes of the same type or nodes of different types. In some scenarios, the roles of the RAN node 110 and the terminal 120 are relative, for example, Figure 1 The network element 120i may be a helicopter or a drone, which may be configured as a mobile base station. For the terminals 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal. The RAN node 110 and the terminal 120 are sometimes referred to as communication devices, for example Figure 1 The base stations 110a and 110b may be understood as communication devices having base station functions, and the terminals 120a-120j may be understood as communication devices having terminal functions.

[0073] In one possible scenario, a RAN node may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. A RAN node may be a macro base station (e.g. Figure 1 110a in), micro base stations or indoor stations (such as Figure 1110b in the description), a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the RAN node may also be a server, a wearable device, a vehicle or an on-board device, etc. For example, the access network device in the vehicle to everything (V2X) technology may be a road side unit (RSU). All or part of the functions of the RAN node in the present application may also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (such as a cloud platform). The RAN node in the present application may also be a logical node, a logical module or software that can implement all or part of the functions of the RAN node.

[0074] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, and different RAN nodes respectively implement part of the functions of the base station. For example, the RAN node can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU here completes the functions of the radio resource control protocol and the packet data convergence layer protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned various protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The CU and DU can be set separately, or can also be included in the same network element, such as the baseband unit (BBU). The RU may be included in a radio frequency device or a radio frequency unit, for example, in a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH).

[0075] Optionally, the RAN node may also be expressed in different ways, such as access network equipment. Unless otherwise specified in this application, access network equipment is used for expression.

[0076] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, CU, CU-CP, CU-UP, DU and RU are described as examples in this application. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0077] The terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, mobile equipment (ME), etc. The terminal can be widely used in various scenarios, for example, device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present application do not limit the device form of the terminal.

[0078] The core network may include one or more functional entities (or core network elements, network elements, entities, etc.), such as network slice selection function (NSSF), network exposure function (NEF), network storage function (NRF), policy control function (PCF), unified data management (UDM), access and mobility management function (AMF), authentication server function (AUSF), session management function (SMF), etc.

[0079] It should be noted that the above functional entity is only a name, and the name itself does not limit the entity. For example, the session management function may also be replaced by "session management function entity" or other names. Moreover, the session management function entity may also correspond to an entity including other functions in addition to the session management function. The user plane function may also be replaced by "user plane function entity" or other names, and the user plane function entity may also correspond to an entity including other functions in addition to the user plane function. A unified explanation is given here, and no further description is given below.

[0080] It should be noted that the message names between network elements or the names of parameters in the messages in the following embodiments of the present application are merely examples, and other names may be used in specific implementations, and the embodiments of the present application do not impose any specific limitations on this.

[0081] In this application, "sending information to...(terminal)" can be understood as the destination of the information being the terminal. It can include sending information to the terminal directly or indirectly. "Receiving information from...(terminal)" can be understood as the source of the information being the terminal, which can include receiving information from the terminal directly or indirectly. The information may be processed as necessary between the source and destination of the information, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated here.

[0082] It should be understood that the terminal device in the embodiment of the present application can be any of the above-mentioned devices or chips, which are not specifically limited here. Whether as a device or as a chip, the terminal device can be manufactured, sold or used as an independent product. In this embodiment and subsequent embodiments, only the terminal device is used as an example for introduction.

[0083] It should be understood that the device used to implement the function of the access network device in the embodiment of the present application may be the access network device itself, or may be a device that can support the access network device to implement the function, such as a chip system or a combination device or component that can implement the function of the access network device, and the device can be installed in the access network device. In the embodiment of the present application, the chip system may be composed of chips, or may include chips and other discrete devices. In this embodiment and subsequent embodiments, only the access network device is used as an example for introduction.

[0084] The following is an explanation of the relevant technical features involved in the embodiments of the present application. It should be noted that these explanations are intended to make the embodiments of the present application easier to understand and should not be regarded as limiting the scope of protection claimed by the present application.

[0085] 1. MBS

[0086] MBS is a new feature introduced by the NR system. Terminal devices supporting MBS can reside in NR cells supporting MBS to receive broadcast information. In addition, terminal devices residing in NR cells supporting MBS can also perform unicast services (such as voice data services, etc.) normally.

[0087] 2. Idle state (i.e. idle state) and connected state (i.e. connected state)

[0088] In some embodiments of the present application, the state of the terminal device may include a connected state and an idle state. Wherein, when the terminal device is powered on but no radio resource control (RRC) connection is established with the network side, the terminal device is in an idle state. When the terminal device establishes an RRC connection with the network side, the terminal device is in a connected state.

[0089] It can be understood that the processes that the terminal equipment in the idle state needs to complete include public land mobile network (PLMN) selection, cell selection / cell reselection, location registration, etc.

[0090] 3. Cell

[0091] A cell is an area within the wireless coverage of an access network device (e.g., a base station). In this area, a terminal device can reliably communicate with the access network device via wireless signals. It can be understood that the coverage of each access network device can be divided into one or more cells, and each cell can correspond to one or more frequency points. It can also be understood that each cell is an area formed by the coverage of one or more frequency points.

[0092] In some embodiments of the present application, different cells may correspond to the same access network device. That is, the access network device to which cell A belongs and the access network device to which cell B belongs may be the same access network device. For example, cell A and cell B may be managed by the same base station. In this case, cell A and cell B may be referred to as co-stationed.

[0093] In some embodiments of the present application, different cells may correspond to different access network devices. That is, the access network device to which cell A belongs and the access network device to which cell B belongs may be different access network devices. For example, cell A and cell B may be managed by different access network devices. For another example, cell A and cell B may be managed by the same access network device, but the radio frequency processing units corresponding to cell A and cell B are different radio frequency processing units in the same access network device.

[0094] An adjacent cell, or neighboring cell, or neighboring cell, refers to an area within the wireless coverage of an access network device that is physically associated with the current serving cell and transmits signals on the same frequency or a different frequency. In other words, an adjacent cell refers to a cell that is connected to or adjacent to the current serving cell. In layman's terms, an adjacent cell can be understood as a "surrounding cell" of the current serving cell.

[0095] 4. Cell handover (HO)

[0096] Cell switching refers to the process of migrating the communication link between a terminal device and a current access network device to another access network device in mobile communications. In a wireless communication system, when a terminal device moves from one cell to another or approaches another cell, switching is required to keep the communication of the terminal device uninterrupted. The switching can be intra-site switching or inter-site switching, and this application does not impose specific restrictions on this. Intra-site switching refers to the source cell and the target cell belonging to the same access network device (for example, a base station). Inter-site switching refers to the source cell and the target cell belonging to different access network devices (for example, a base station).

[0097] In this application, the source cell refers to the cell that provides services to the terminal device before the handover, and the target cell refers to the cell that provides services to the terminal device after the handover. For the convenience of description, this application records the access network device corresponding to the source cell as the source access network device, and the access network device corresponding to the target cell as the target access network device. It is understandable that the source access network device and the target access network device can be the same network device or different access network devices.

[0098] The terminal device can receive the measurement indication sent by the current resident cell, and measure and evaluate the signal quality of the cell based on the measurement indication to obtain the measurement result. The terminal device can generate a corresponding measurement report (measurement report, MR) based on the measurement result, and send the measurement report to the current resident cell. After the current resident cell of the terminal device receives the measurement report, it can communicate with the target cell based on the measurement report. If the target cell allows access, the current resident cell of the terminal device can instruct the terminal device to switch the cell. It can be understood that the cell switching is performed when the terminal device is in a connected state, and the cell switching can keep the communication of the terminal device uninterrupted.

[0099] 5. Measurement report (MR)

[0100] The 3rd Generation Partnership Project (3GPP) specification proposes a set of predefined measurement reporting mechanisms to be performed by terminal devices. These predefined measurement reporting types are called "events". The type of "event" that the terminal device must report is specified by the RRC signaling message sent by the access network device (for example, the RRC connection reconfiguration message in the first step of the above handover process).

[0101] The event types of measurement reports are described in detail below.

[0102] (1) Event types for switching within the system

[0103] Event A1: The serving cell signal quality is higher than an absolute threshold (Serving becomes better than threshold), in dBm.

[0104] Event A2: The serving cell signal quality is lower than an absolute threshold (Serving becomes worse than threshold), in dBm.

[0105] Event A3: The signal quality of the neighboring cell (or neighboring cell, ie, adjacent cell) is higher than the signal quality of the current serving cell by a relative value (neighbor becomes offset better than SpCell), in dB.

[0106] Event A4: The signal quality of the neighboring cell is higher than an absolute threshold (Neighbour becomes better than threshold), in dBm.

[0107] Event A5: The signal quality of the serving cell is lower than an absolute threshold threshold1, and the signal quality of the neighboring cell is higher than an absolute threshold threshold2 (SpCell becomes worse than threshold1 and neighbor becomes better than threshold2), unit: dBm.

[0108] (2) Event types for switching between systems

[0109] Event B1: The signal quality of the inter-RAT neighboring cell is higher than an absolute threshold (Inter RAT neighbor becomes better than threshold), in dBm.

[0110] Event B2: The signal quality of the serving cell is lower than an absolute threshold threshold1, and the signal quality of the inter-RAT neighbor cell is higher than an absolute threshold threshold2 (PCell becomes worse than threshold1 and inter RAT neighbor becomes better than threshold2), unit: dBm.

[0113] in:

[0114] S201, an access network device sends first measurement configuration information to a terminal device in a first cell. Correspondingly, the terminal device receives the first measurement configuration information from the access network device in the first cell.

[0115] Here, the first cell is the current serving cell of the terminal device, or the first cell is the cell where the terminal device currently resides. In addition, an RRC connection is established between the terminal device and the first cell, or the terminal device is described as being in a connected state.

[0116] In one possible scenario, the first cell is an NR cell, and in another possible scenario, the first cell is an LTE cell. The relevant parts below will respectively explain the cases where the first cell is an NR cell and an LTE cell.

[0117] In some feasible implementations, the first measurement configuration information may include at least one measurement frequency and at least one measurement event. The at least one measurement frequency includes a first measurement frequency, a second measurement frequency, etc., and the at least one measurement event includes a first measurement event, a second measurement event, etc. The first measurement frequency may be a frequency supporting MBS (or described as the first measurement frequency being an MBS frequency of interest to the user), and the second measurement frequency may be a frequency not supporting MBS, wherein the first measurement frequency is associated with a first measurement event, the second measurement frequency is associated with a second measurement event, the first measurement event corresponds to a first evaluation threshold and a first evaluation duration, and the second measurement event corresponds to a third evaluation threshold and a third evaluation duration.

[0118] S202: When it is determined that the reporting condition of the first measurement event is met according to the measurement result of the cell at the first measurement frequency, the second evaluation threshold value, and the second evaluation duration, the terminal device sends a measurement report of the first measurement event to the access network device. Correspondingly, the access network device receives the measurement report of the first measurement event from the terminal device.

[0119] In some feasible implementations, the cell on the first measurement frequency is a cell supporting MBS (or described as an NR cell supporting MBS). The second evaluation threshold value is less than the first evaluation threshold value, and the second evaluation duration is less than or equal to the first evaluation duration, or the second evaluation threshold value is equal to the first evaluation threshold value, and the second evaluation duration is less than the first evaluation duration. That is to say, the second evaluation threshold value is less than or equal to the first evaluation threshold value, the second evaluation duration is less than or equal to the first evaluation duration, and the situations of being equal cannot exist at the same time. It is understandable that the method of reducing the evaluation threshold value of the cell supporting MBS and / or shortening the evaluation duration of the cell supporting MBS in the present application can promote the priority reporting of the first measurement event associated with the first measurement frequency.

[0120] Optionally, in some feasible implementations, the priority reporting of the first measurement event associated with the first measurement frequency can also be promoted by increasing the evaluation threshold of the cell that does not support MBS and / or lengthening the evaluation duration of the cell that does not support MBS. Therefore, for the cell on the second measurement frequency (the cell on the second measurement frequency is the cell that does not support MBS), when the reporting condition of the second measurement event is determined to be met according to the measurement result of the cell on the second measurement frequency, the fourth evaluation threshold value and the fourth evaluation duration, the terminal device can send a measurement report of the second measurement event to the access network device. Among them, the fourth evaluation threshold value is greater than the third evaluation threshold value, and the fourth evaluation duration is greater than or equal to the third evaluation duration; or, the fourth evaluation threshold value is equal to the third evaluation threshold value, and the fourth evaluation duration is greater than the third evaluation duration, that is, the fourth evaluation threshold value is greater than or equal to the third evaluation threshold value, the fourth evaluation duration is greater than or equal to the third evaluation duration, and the equal situations cannot exist at the same time.

[0121] The following describes the case where the first cell is a NR cell or a LTE cell.

[0122] Case 1: The first cell is an NR cell:

[0123] 1. The first measurement event may be an A3 event. Therefore, when the difference between the measurement result of the cell at the first measurement frequency point and the measurement result of the first cell within the second evaluation period is greater than or equal to the second evaluation threshold value, it can be determined that the reporting condition of the A3 event is met.

[0124] 2. The first measurement event may be an A4 event. Therefore, when the measurement results of the cells at the first measurement frequency point within the second evaluation time period are greater than or equal to the second evaluation threshold value, it is determined that the reporting condition of the A4 event is met.

[0125] 3. The first measurement event may be an A5 event. Therefore, when the measurement results of the cell at the first measurement frequency point within the second evaluation time period are greater than or equal to the second evaluation threshold value 1, and the measurement results of the first cell within the second evaluation time period are less than the second evaluation threshold value 2, it is determined that the reporting conditions of the A5 event are met.

[0126] It can be understood that MBS is a new feature supported by NR cells. When the first cell is an NR cell, the first cell and the cell on the first measurement frequency point are cells of the same system. Therefore, the first measurement event can be an A event, such as an A3 event, an A4 event or an A5 event.

[0127] Case 2: The first cell is an LTE cell:

[0128] 1. The first measurement event may be a B1 event. Therefore, when the measurement results of the cells at the first measurement frequency point within the second evaluation time period are greater than or equal to the second evaluation threshold value, it is determined that the reporting condition of the B1 event is met.

[0129] 2. The first measurement event may be a B2 event. Therefore, when the measurement results of the cell at the first measurement frequency point within the second evaluation time period are greater than or equal to the second evaluation threshold value 1, and the measurement results of the first cell within the second evaluation time period are less than the second evaluation threshold value 2, it is determined that the reporting conditions of the B2 event are met.

[0130] It can be understood that MBS is a new feature supported by NR cells. When the first cell is an NR cell, the first cell and the cell on the first measurement frequency point are cells of different systems. Therefore, the first measurement event can be a B event, such as a B1 event or a B2 event.

[0131] It should be noted that, when the first cell is an LTE cell, if the access network device has configured the first measurement configuration information for the terminal device, the terminal device can trigger the reporting of the first measurement event by adjusting the evaluation threshold value and / or evaluation duration of the measurement event in the first measurement configuration information. For example, the promotion method includes lowering the evaluation threshold value of the MBS cell and / or shortening the evaluation duration of the MBS cell. Optionally, the promotion method may also include increasing the evaluation threshold of the non-MBS cell and / or lengthening the evaluation duration of the non-MBS cell. When the first cell is an LTE cell, if the access network device has not configured the first measurement configuration information for the terminal device, the access network device may first configure the second measurement configuration information for the terminal device, and trigger the access network device to configure the first measurement configuration information for the terminal device by promoting the reporting of the third measurement event in the second measurement configuration information. That is, when the access network device has not configured the first measurement configuration information for the terminal device, before S201, the following steps may also be included: Figure 2 Not shown yet):

[0132] S1. The access network device sends second measurement configuration information to a terminal device in a first cell. Correspondingly, the terminal device receives the second measurement configuration information from the first cell.

[0133] The second measurement configuration information includes a third measurement event, and the third measurement event corresponds to a fifth evaluation threshold value and a fifth evaluation duration. Exemplarily, the third measurement event may be an A2 event, etc., which is not limited here.

[0134] S2. When the reporting condition of the third measurement event is determined to be met according to the measurement result of the first cell, the sixth evaluation threshold value, and the sixth evaluation duration, the terminal device sends a measurement report of the third measurement event to the access network device. Correspondingly, the access network device receives the measurement report of the third measurement event from the terminal device.

[0135] Among them, the measurement report of the third measurement event is used to trigger the sending of the first measurement configuration information. The sixth evaluation threshold value is greater than the fifth evaluation threshold value, and the sixth evaluation duration is less than or equal to the fifth evaluation duration, or the sixth evaluation threshold value is equal to the fifth evaluation threshold value, and the sixth evaluation duration is less than the fifth evaluation duration. In other words, the sixth evaluation threshold value is greater than or equal to the fifth evaluation threshold value, the sixth evaluation duration is less than or equal to the fifth evaluation duration, and the equal situations cannot exist at the same time. It is understandable that the method of increasing the evaluation threshold value of the third measurement event and / or shortening the evaluation duration of the third measurement event in the present application can promote the reporting of the third measurement event, and then can prompt the access network device to send the first measurement configuration information to the terminal device according to the received measurement report of the third measurement event. Taking the third measurement event as A2 event as an example, under normal circumstances, if the network receives an A2 event report, it means that the current service cell is poor. If there is an NR neighboring cell, it will prompt the network to send the B event configuration to evaluate the current NR neighboring cell quality. The B1 event or B2 event measurement report indicates that the neighboring cell quality meets the requirements, and the network will drive the terminal device to move to the NR neighboring cell by sending a switching command.

[0136] S203: The access network device sends a switching command to the terminal device. Correspondingly, the terminal device receives the switching command from the access network device.

[0137] The switching command is used to instruct the terminal device to switch to the cell on the first measurement frequency. It is understandable that the cell on the first measurement frequency is a cell that supports MBS. Therefore, after the terminal device successfully switches to the cell on the first measurement frequency, the terminal device can obtain MBS services, for example, the user can watch MBS programs.

[0138] In an embodiment of the present application, no matter whether the terminal device currently resides in an NR network or an LTE network, when the terminal device enters a connected state, by promoting the priority reporting of measurement events of cells supporting MBS, the access network device can drive the terminal device to switch / move to a cell supporting MBS through a switching command, thereby ensuring the user's demand for watching broadcast programs without affecting the unicast service, which is conducive to improving the user experience.
