Description

Multimedia broadcast multicast service MBS processing method, terminal equipment, base station, device and medium

[0001] This disclosure claims priority to a Chinese patent application filed with the Patent Office of China on February 5, 2024, with application number 202410164666.4 and invention name “Multimedia Broadcast Multicast Service MBS Processing Method, Terminal Equipment, Base Station, Device and Medium”, the entire contents of which are incorporated by reference in this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to a multimedia broadcast multicast service (MBS) processing method, terminal equipment, base station, apparatus, and medium. Background Art

[0003] Non-terrestrial networks (NTN) refer to technologies that wirelessly connect terminal devices and base stations using satellites as a communication relay. NTN cells cover a large area and typically include earth-fixed cells (EFC), quasi-earth-fixed cells (QEFC), and earth-moving cells (EMC). This enables NTN to provide continuous network coverage for terminal devices in scenarios such as deserts and oceans.

[0004] Existing NTN cells cover a large area and may cover multiple MBS service areas. If terminal devices can receive the broadcast / multicast service (MBS) broadcast and / or multicast in the entire NTN cell, it will not only increase interference and power consumption to the terminal devices, but also cause leakage problems. Summary of the Invention

This reduces interference and power consumption on the terminal device and improves communication security and reliability.

[0123] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0133] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present disclosure, 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 are within the scope of protection of the present disclosure.

[0134] For example, FIG1 is a schematic diagram of an NTN network structure according to an embodiment of the present disclosure. For ease of understanding, FIG1 considers NTN satellite 110 and NTN gateway 120 as part of a gNB. As shown in FIG1 , a service link exists between NTN satellite 110 and a terminal device, and a feeder link exists between NTN satellite 110 and NTN gateway 120. Through this network structure, NTN satellite 110 can transparently forward data from a base station to a terminal device. Similarly, data from a terminal device can be transparently forwarded to NTN gateway 120 and a base station via NTN satellite 110. As described in the background, NTN cells generally fall into three categories: EFC, where the coverage of an NTN satellite 110 remains constant, such as a cell projected on the ground by a GEO satellite (a geostationary orbit satellite); EFC, where the beam of an NTN satellite 110 stably covers a fixed area on the Earth's surface for a period of time; and EMC, where the coverage of an NTN satellite 110 beam slides across the Earth's surface, changing with the satellite's movement. Regardless of the type of NTN cell, the area covered by the NTN cell is relatively large and may cover multiple broadcast / multicast service (MBS) service areas. If the MBS broadcast and / or multicast service is broadcast and / or multicast in the entire NTN cell (i.e., all MBS service areas covered by the NTN cell), the terminal device will be able to receive the MBS broadcast and / or multicast service at any location in the NTN cell. This will not only increase interference and power consumption to the terminal device, but also cause leakage problems. For example, the terminal device may receive MBS broadcast and / or multicast services from other countries or regions.

[0135] In order to solve the above problems, the embodiments of the present disclosure provide a method for processing a multimedia broadcast multicast service MBS, which is described below in conjunction with specific embodiments.

[0136] Figure 2 is a flow chart illustrating a method for processing a multimedia broadcast multicast service (MBS) according to an embodiment of the present disclosure. This method can be performed by a multimedia broadcast multicast service (MBS) processing device, wherein the device can be implemented using software and / or hardware and is generally integrated into a terminal device. The terminal device involved in the embodiments of the present disclosure can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. The name of the terminal device may vary in different systems. For example, in a 5G system, the terminal device may be referred to as a user equipment (UE). A wireless terminal device can be a USB storage device, other personal computer memory devices, or a dongle. It can also communicate with one or more core networks (CNs) via a radio access network (RAN). A wireless terminal device can be a mobile terminal device, such as a mobile phone (also known as a "cellular" phone) or a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), personal computers, tablet computers, Machine-type Communication (MTC) terminal devices, etc. Wireless terminal devices may also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, access points, remote terminal devices, access terminal devices, user terminal devices, user agents, user devices, and wireless access points and routers / modems that meet the limitations of this definition, but are not limited in the embodiments of the present disclosure.

[0137] As shown in FIG2 , the method includes:

[0138] S210: Receive first information sent by a base station, where the first information includes: a correspondence between first MBS service area information and MBS broadcast and / or multicast information.

[0139] In an embodiment of the present disclosure, after acquiring the first information, the base station may send the first information to the terminal device, so that the terminal device can receive the first information sent by the base station. The first information includes a correspondence between the first MBS service area information and the MBS broadcast information, and / or a correspondence between the first MBS service area information and the MBS multicast information. The correspondence between the first MBS service area information and the MBS broadcast information indicates that the MBS broadcast service corresponding to the MBS broadcast information is broadcast within the scope of the first MBS service area indicated by the first MBS service area information. The correspondence between the first MBS service area information and the MBS multicast information indicates that the MBS multicast service corresponding to the MBS multicast information is multicast within the scope of the first MBS service area indicated by the first MBS service area information.

[0140] Specifically, the first MBS service area information is used to represent the geographical area covered by the first MBS service area (ie, the scope of the first MBS service area).

[0141] There are many specific representation forms of the first MBS service area information. Typical examples are described below, but do not constitute a limitation to the present disclosure.

[0142] In some embodiments, the first MBS service area information may include a geographic location area identifier, a beam identifier and / or a mapped cell ID.

[0143] Specifically, the geographic location area identifier includes geographic location information for defining a geographic area.

[0144] In some examples, the geographic location area identifier may include a central location point and a distance threshold from the central location. The circular area defined by the central location as the center and the distance threshold as the radius is the scope of the first MBS service area. The central location may be represented by three-dimensional coordinates or longitude and latitude, but is not limited thereto.

[0145] In other examples, the geographic location area identifier may include multiple reference locations, and a polygonal area defined by connecting the multiple reference locations is the range of the first MBS service area. The reference locations may be represented by three-dimensional coordinates or longitude and latitude, but are not limited thereto.

[0146] It is understandable that the first MBS service area information includes a geographical location area identifier, which can make the first MBS service area information clearer and more intuitive, and facilitate the terminal device to understand the first MBS service area information.

[0147] Specifically, the beam identifier is a mark for indicating the beam, or in other words, an index of the beam. In this case, the geographical area covered by the beam indicated by the beam identifier is the range of the first MBS service area.

[0148] Specifically, the mapped cell ID is a mark for indicating a geographical area, or an index of the geographical area. In this case, the geographical area indicated by the mapped cell ID is the range of the first MBS service area.

[0149] For example, the mapping relationship between the mapped cell ID and the geographical area can be configured by the Radio Access Network (RAN) and the core network. A geographical location point can be mapped to multiple mapped cell IDs, and the mapped cell ID can be used to distinguish different geographical areas (such as overlapping areas).

[0150] It can be understood that the first MBS service area information includes a beam identifier, which can make the representation of the first MBS service area information concise and with a small amount of data, which is conducive to reducing the data volume of the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information, thereby reducing the transmission cost; and since the terminal device can only perform MBS service reception in the beam corresponding to the MBS service that the terminal device is interested in, it also has better security and privacy.

[0151] Specifically, MBS broadcast information is used to introduce MBS broadcast services. MBS multicast information is used to introduce MBS multicast services. MBS broadcast services and MBS multicast services can be expressed in various forms, such as, but not limited to, MBS sessions.

[0152] MBS broadcast and / or multicast information may include various specific contents. Typical examples are described below, but they do not limit the present disclosure.

[0153] In some embodiments, the MBS broadcast and / or multicast information includes: an MBS session, an MBS session index, a Radio Network Temporary Identity (RNTI) of a common group groupCommon, or a specific configuration identifier MBS-RNTI-SpecificConfigId indicating multicast indication information.

[0154] Accordingly, the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information includes:

[0155] The correspondence between the first MBS service area information and the MBS session, or,

[0156] The correspondence between the first MBS service area information and the MBS session index, or,

[0157] The correspondence between the first MBS service area information and the radio network temporary identifier RNTI of the common group groupCommon, where the groupCommon RNTI includes: a C-RNTI representing the MBS service, or a G-RNTI or G-CS-RNTI representing the group; or

[0158] The correspondence between the first MBS service area information and the specific configuration identifier MBS-RNTI-SpecificConfigId indicating the multicast indication information.

[0159] Specifically, the common group groupCommon is a special channel used to transmit control signaling. The groupCommon RNTI is a radio network temporary identifier specifically used to indicate a common control channel.

[0160] Specifically, the C-RNTI is the RNTI used to identify the MBS service. It identifies the specific configuration and parameters required for the MBS service and uniquely identifies an MBS service within the system. Using the C-RNTI, the system can allocate and schedule resources for the MBS service to support the transmission of multimedia broadcast and multicast services.

[0161] Specifically, the G-RNTI is used to represent a group RNTI. A group is a group of users (UEs) that share the same configuration or parameters and communicate over a control channel. The G-RNTI identifies a specific group and enables the system to schedule and allocate resources to users within the group.

[0162] Specifically, the G-CS-RNTI is an RNTI used to indicate Group Configured Scheduling. A group common system refers to the specific system configuration and parameters provided for multimedia broadcast and multicast services within a group. The G-CS-RNTI identifies a specific group common system and enables the system to transmit multimedia broadcast and multicast data within the group.

[0163] Specifically, MBS-RNTI-SpecificConfigId is indication information for indicating the multicast RNTI.

[0164] Specifically, in the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information, there are multiple setting methods for the number of MBS broadcast and / or multicast information corresponding to one first MBS service area information, the number of first MBS service area information corresponding to one MBS broadcast information, and the number of first MBS service area information corresponding to one MBS multicast information. Typical examples are described below, but do not constitute a limitation of the present disclosure.

[0165] In some examples, the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information includes: one piece of first MBS service area information corresponds to one piece of MBS broadcast and / or multicast information.

[0166] Specifically, one first MBS service area information corresponds to one MBS broadcast information, or one first MBS service area information corresponds to one MBS multicast information, or one first MBS service area information corresponds to one MBS broadcast information and one MBS multicast information.

[0167] It can be understood that one first MBS service area information corresponds to one MBS broadcast and / or multicast information, which can reduce the number of broadcast and / or multicast MBS broadcast and / or multicast services within the scope of each first MBS service area, which is beneficial to reducing the number of MBS broadcast and / or multicast services listened to by the terminal device, thereby reducing interference and power consumption to the terminal device.

[0168] In some other examples, the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information includes: one first MBS service area information corresponds to a plurality of MBS broadcast and / or multicast information.

[0169] Specifically, one first MBS service area information corresponds to multiple MBS broadcast information, or one first MBS service area information corresponds to multiple MBS multicast information, or one first MBS service area information corresponds to multiple MBS broadcast information and multiple MBS multicast information.

[0170] Of course, one piece of first MBS service area information may also correspond to multiple pieces of MBS broadcast information and one piece of multicast information, or one piece of first MBS service area information may also correspond to one piece of MBS broadcast information and multiple pieces of multicast information.

[0171] It is understandable that one first MBS service area information corresponds to multiple MBS broadcast and / or multicast information, so that for each MBS broadcast and / or multicast service, there are more first MBS service areas that can be selectively broadcast and / or multicast, which is more flexible.

[0172] In some further examples, a plurality of first MBS service area information corresponds to one piece of MBS broadcast and / or multicast information.

[0173] Specifically, multiple first MBS service area information corresponds to one MBS broadcast information, or multiple first MBS service area information corresponds to one MBS multicast information, or multiple first MBS service area information corresponds to one MBS broadcast information and one MBS multicast information.

[0174] It can be understood that multiple first MBS service area information corresponds to one MBS broadcast and / or multicast information, so that for each MBS broadcast and / or multicast service, it can be broadcast and / or multicast in more first MBS service areas, which is conducive to meeting the MBS broadcast and / or multicast service's requirements for broadcasting and / or multicasting within a larger range (or a larger area).

[0175] Specifically, the message or information used to transmit the first information between the base station and the terminal device can be set by those skilled in the art according to actual conditions and is not limited here. The following will be described with reference to typical examples, but does not constitute a limitation of the present disclosure.

[0176] In some embodiments, the first information sent by the base station may be received via a broadcast message, a non-access stratum (NAS) message, or a radio resource control (RRC) dedicated signaling.

[0177] It can be understood that NAS messages and RRC dedicated signaling have the advantages of high reliability. Broadcast messages can notify all terminal devices in the cell and are more suitable for UE in RRC_IDLE / RRC_INACTIVE state. Therefore, the terminal device receives the first information sent by the base station through NAS messages or RRC dedicated signaling, which can improve the reliability of receiving the first information; sending the first information through broadcast messages can increase the range of receiving terminals of the first information, ensuring that RRC_IDLE / INACTIVE terminal devices can also receive it.

[0178] In some embodiments, receiving the first information sent by the base station includes: when it is determined that the terminal device meets the first condition, receiving the first information sent by the base station.

[0179] Specifically, there are many specific configuration methods that meet the first condition. Typical examples are described below, but they do not constitute a limitation to the present disclosure.

[0180] In some examples, the first condition includes: the terminal device obtains indication information of supporting MBS broadcast and / or multicast services in the current serving cell.

[0181] Specifically, the current cell mentioned here may be the cellular cell where the terminal device is currently located, or may be the MBS service area where the terminal device is currently located, etc., without limitation.

[0182] Specifically, the indication information supporting MBS broadcast and / or multicast services may be received from the core network, other terminal devices located in the current serving cell, or a base station corresponding to the current serving cell, etc., without limitation.

[0183] In some other examples, the first condition includes: after the terminal device performs cell reselection, it obtains indication information of supporting MBS broadcast and / or multicast services in the reselected new cell.

[0184] Specifically, the reselected new cell mentioned here may be a cellular cell, or an MBS service area, etc., but is not limited thereto.

[0185] It can be understood that when the terminal device obtains the indication information of supporting MBS broadcast and / or multicast services, it can receive the first information, and then listen to the MBS broadcast and / or multicast services corresponding to the MBS broadcast and / or multicast information based on the first information. Only terminal devices with the authority to listen to MBS broadcast and / or multicast information can obtain the first information. In this way, the interference and power consumption of the first information on the terminal device can be reduced, and the security and reliability of the transmission of the first information can be improved.

[0186] In some other examples, the first condition includes: the terminal device reselects to a new cell after performing cell reselection.

[0187] Specifically, the cell reselection mentioned here may be cellular cell reselection or MBS service area reselection, etc., and is not limited to this.

[0188] In some further examples, the first condition includes: the remaining power of the terminal device is greater than a preset power threshold.

[0189] It can be understood that when the terminal device meets the first condition, it can receive the first information, and then listen to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information based on the first information, which can increase the threshold for the terminal device to listen to the MBS broadcast and / or multicast service and reduce the interference and power consumption of the first information on the terminal device.

[0190] Of course, in other embodiments, the terminal device may also unconditionally receive the first information sent by the base station, that is, no restriction is set on the terminal device receiving the first information sent by the base station.

[0191] S220: Listen to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information based on the corresponding relationship.

[0192] In the embodiment of the present disclosure, after acquiring the first information, the terminal device may listen to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information in the corresponding relationship based on the corresponding relationship.

[0193] In some embodiments, listening to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information based on the correspondence includes: responding to the user's MBS service reception demand, listening to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information based on the correspondence.

[0194] Specifically, in response to the user's MBS service reception needs, the network access NAS layer of the terminal device will trigger the MBS broadcast and / or multicast service reception operation, and then listen to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information based on the first information.

[0195] It can be understood that in response to the user's MBS service reception needs, the MBS broadcast and / or multicast services corresponding to the MBS broadcast and / or multicast information are listened to based on the corresponding relationship, so that terminal devices that do not have MBS service reception needs will not listen to the MBS broadcast and / or multicast services corresponding to the MBS broadcast and / or multicast information, thereby reducing interference and power consumption to the terminal devices.

[0196] In other embodiments, the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information includes: a correspondence between a geographic area identifier representing the range of the first MBS service area and the MBS broadcast and / or multicast information, wherein the geographic area identifier includes: a center position, or a distance threshold from the center position.

[0197] Accordingly, listening to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information based on the corresponding relationship includes: determining the target center position and the target distance threshold corresponding to the target MBS broadcast and / or multicast information to be received based on the corresponding relationship; when the distance between the position of the terminal device and the target center position is less than the target distance threshold, listening to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information.

[0198] In some embodiments, when the distance between the terminal device and the target center position is greater than or equal to a target distance threshold, the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information is not monitored.

[0199] Specifically, the target MBS broadcast and / or multicast information includes the MBS broadcast and / or multicast information of the MBS broadcast and / or multicast service to be received by the terminal device (i.e., the target MBS broadcast and / or multicast service). In other words, the target MBS broadcast and / or multicast information includes the MBS broadcast information of the MBS broadcast service to be received by the terminal device (i.e., the target MBS broadcast service) and / or the MBS multicast information of the MBS multicast service to be received (i.e., the target MBS multicast service). It should be noted that the number of target MBS broadcast services and target MBS multicast services can be one or more, and this disclosure does not limit this. It should also be noted that the target MBS broadcast service and the target MBS multicast service can be indicated by the core network, base station, or other terminal devices, or can be selected by the terminal device based on the MBS broadcast and / or multicast information in the corresponding relationship, but is not limited to this.

[0200] Specifically, the target center position and the target distance threshold are the center position and the distance threshold corresponding to the target MBS broadcast and / or multicast information in the corresponding relationship.

[0201] Specifically, if the distance between the terminal device and the target center position is less than the target distance threshold, it indicates that the terminal device has entered the scope of the first MBS service area broadcast and / or multicast of the broadcast and / or multicast target MBS; if the distance between the terminal device and the target center position is greater than or equal to the target distance threshold, it indicates that the terminal device is outside the scope of the first MBS service area broadcast and / or multicast of the broadcast and / or multicast target MBS.

[0202] In yet other embodiments, the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information includes: a correspondence between a geographic area identifier representing the scope of the first MBS service area and the MBS broadcast and / or multicast information, wherein the geographic area identifier includes: a plurality of reference locations. Accordingly, based on the correspondence, listening to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information includes: determining, based on the correspondence, a plurality of target reference locations corresponding to target MBS broadcast and / or multicast information to be received; and, when the terminal device is located within a polygonal area formed by the plurality of target reference locations, listening to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information.

[0203] In some embodiments, when the terminal device is located outside the polygonal area, the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information is not monitored.

[0204] Specifically, the target reference position is a reference position corresponding to the target MBS broadcast and / or multicast information in the corresponding relationship.

[0205] Specifically, if the position of the terminal device is within the polygonal area connected by multiple target reference positions, it indicates that the terminal device has entered the scope of the first MBS service area broadcast and / or multicast by the broadcast and / or multicast target MBS. If the terminal device is outside the polygonal area connected by multiple target reference positions, it indicates that the terminal device is outside the scope of the first MBS service area broadcast and / or multicast by the broadcast and / or multicast target MBS.

[0206] It can be understood that based on the target center position and the target distance threshold, or multiple target reference positions, determining whether the terminal device is located within the scope of the first MBS service area of ​​the broadcast and / or multicast target MBS broadcast and / or multicast, the determination method is simple, which is conducive to reducing the difficulty of determining whether the terminal device is located within the scope of the first MBS service area of ​​the broadcast and / or multicast target MBS broadcast and / or multicast.

[0207] It can also be understood that when the distance between the location of the terminal device and the target center location is less than the target distance threshold, or when the location of the terminal device is within a polygonal area connected by multiple target reference locations, the terminal device listens to the target MBS broadcast and / or multicast service, otherwise the terminal device does not listen to the target MBS broadcast and / or multicast service, so that the terminal device can only listen to the target MBS broadcast and / or multicast service when it is within the scope of the first MBS service area of ​​the broadcast target MBS broadcast service (multicast target MBS multicast service). In this way, terminal devices located outside the scope of the first MBS service area of ​​the broadcast target MBS broadcast service (multicast target MBS multicast service) can be prevented from listening to the target MBS broadcast and / or multicast service, thereby reducing the risk of leakage of the target MBS broadcast and / or multicast service and improving the security and reliability of communication.

[0208] In some further embodiments, the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information includes: the correspondence between the beam identifier representing the range of the first MBS service area and the MBS broadcast and / or multicast information; the first information also includes: a signal quality threshold corresponding to the beam identifier, wherein the signal quality threshold includes: a reference signal received power RSRP threshold, or a reference signal received quality RSRQ threshold, or a signal to interference plus noise ratio SINR threshold.

[0209] Accordingly, listening to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information based on the corresponding relationship includes: determining at least one target beam identifier corresponding to the target MBS broadcast and / or multicast information to be received based on the corresponding relationship; obtaining a target signal quality threshold corresponding to the target beam identifier based on the first information; and listening to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information when the target beam signal quality corresponding to the target beam identifier is higher than the target signal quality threshold. In some embodiments, when there are multiple target beam identifiers, and the signal qualities of the multiple target beams corresponding to the multiple target beam identifiers are all higher than the corresponding target signal quality thresholds, the target beam with the highest signal quality is selected to listen to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information.

[0210] In some embodiments, when the signal quality of all target beams is lower than or equal to a target signal quality threshold, the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information is not monitored.

[0211] Specifically, the signal quality may include: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), or Signal-to-Interference plus Noise Ratio (SINR). Accordingly, the target signal quality threshold includes: Reference Signal Received Power (RSRP) threshold, or Reference Signal Received Quality (RSRQ) threshold, or Signal-to-Interference plus Noise Ratio (SINR) threshold.

[0212] Specifically, the target beam identifier is the beam identifier corresponding to the target MBS broadcast and / or multicast information in the corresponding relationship, the target beam is the beam pointed to by the target beam identifier, and the target signal quality threshold is the signal quality threshold corresponding to the target beam identifier.

[0213] Specifically, if the target beam signal quality corresponding to the target beam identifier is higher than the target signal quality threshold corresponding to the target beam identifier, it indicates that the target beam signal quality is high and can communicate normally. If the target beam signal quality corresponding to the target beam identifier is less than or equal to the target signal quality threshold corresponding to the target beam identifier, it indicates that the target beam signal quality is poor, which may cause the communication quality to deteriorate or fail to communicate normally. For example, the RSRP threshold refers to a minimum receiving power threshold set in the LTE / NR system, which is used to determine whether the terminal device can normally receive the signal sent by the base station at a certain location. If the RSRP received by the terminal device is higher than the RSRP threshold value, it means that the signal quality is good and can communicate normally. If the RSRP received by the terminal device is lower than or equal to the RSRP threshold value, it means that the signal quality is poor, which may cause the communication quality to deteriorate or fail to communicate normally. The same is true for RSRQ and SINR, which will not be repeated here.

[0214] Specifically, the same target MBS broadcast information (target MBS multicast information) may correspond to a target beam identifier. That is, the same target MBS broadcast service (target MBS multicast service) can be broadcast (multicast) within the geographical area covered by the target beam corresponding to the target beam identifier. In this case, the terminal device can reside on the target beam corresponding to the target beam identifier to listen to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information.

[0215] Specifically, for the same target MBS broadcast information (target MBS multicast information), it may correspond to multiple target beam identifiers, that is, the same target MBS broadcast service (target MBS multicast service) can be broadcast (multicast) within the geographical area covered by the beams corresponding to multiple target beam identifiers, and the target signal quality thresholds corresponding to the multiple target beam identifiers can be the same or different. If the signal qualities of the multiple target beams corresponding to the multiple target beam identifiers are all higher than the corresponding target signal quality thresholds, the terminal device can choose to reside in the target beam with the highest signal quality to listen to the target MBS broadcast and / or multicast service.

[0216] Exemplarily, MBS session 1 is the MBS broadcast service to be received. In the corresponding relationship, the MBS broadcast information of MBS session 1 (i.e., the target MBS broadcast information) corresponds to beam identifier SSB1 and beam identifier SSB2 (i.e., the target beam identifier). The target signal quality thresholds corresponding to beam identifier SSB1 and beam identifier SSB2 can be the same or different. If the signal qualities of the target beams corresponding to beam identifier SSB1 and beam identifier SSB2 are both higher than their respective corresponding target signal quality thresholds, and the signal quality of the target beam corresponding to beam identifier SSB1 is higher than the signal quality of the target beam corresponding to beam identifier SSB2, the terminal device can select the target beam corresponding to beam identifier SSB1 to listen to MBS session 1.

[0217] It can be understood that when the signal quality of the target beam corresponding to the target beam identifier is higher than the target signal quality threshold, the terminal device listens to the target MBS broadcast and / or multicast service, so that the signal quality of the target MBS broadcast and / or multicast service is strong and can communicate normally, the terminal device listens to the target MBS broadcast and / or multicast service, otherwise the terminal device does not listen to the target MBS broadcast and / or multicast service to avoid wasting power and resources to receive useless messages. In this way, interference and power consumption to the terminal device can be reduced.

[0218] It can also be understood that selecting the target beam with the highest signal quality to listen to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information can make the signal strength of the target MBS broadcast and / or multicast service received by the terminal device stronger, thereby reducing the risk of normal communication failure.

[0219] In some further embodiments, the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information includes: a correspondence between a mapped cell identifier representing the range of the first MBS service area and the MBS broadcast and / or multicast information.

[0220] Correspondingly, listening to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information based on the corresponding relationship includes: determining the target mapping cell identifier corresponding to the target MBS broadcast and / or multicast information to be received based on the corresponding relationship; when the current mapping cell identifier corresponding to the terminal device belongs to the target mapping cell identifier, listening to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information.

[0221] In some embodiments, if the current mapped cell identifier does not belong to the target mapped cell identifier, the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information is not monitored.

[0222] Specifically, the target mapping cell identifier is a mapping cell identifier corresponding to the target MBS broadcast and / or multicast information in the corresponding relationship.

[0223] Specifically, there are many specific ways to obtain the current mapping cell identifier, for example, by receiving the current mapping cell identifier sent by the core network, base station, or other terminal devices to obtain the current mapping cell identifier corresponding to the location of the terminal device, but it is not limited to this.

[0224] It can be understood that whether the current mapping cell identifier corresponding to the location of the terminal device belongs to the target mapping cell identifier to determine whether the terminal device is located within the scope of the first MBS service area broadcast and / or multicast of the broadcast and / or multicast target MBS. The judgment method is simple, which is conducive to reducing the difficulty of implementing the judgment of whether the terminal device is located within the scope of the first MBS service area broadcast and / or multicast of the broadcast and / or multicast target MBS.

[0225] It can also be understood that when the current mapping cell identifier corresponding to the location of the terminal device belongs to the target mapping cell identifier, the terminal device listens to the target MBS broadcast and / or multicast service, otherwise the terminal device does not listen to the target MBS broadcast and / or multicast service, so that the terminal device can only listen to the target MBS broadcast and / or multicast service when it is within the scope of the first MBS service area of ​​the broadcast target MBS broadcast service (multicast target MBS multicast service). In this way, terminal devices located outside the scope of the first MBS service area of ​​the broadcast target MBS broadcast service (multicast target MBS multicast service) can be prevented from listening to the target MBS broadcast and / or multicast service, thereby reducing the risk of leakage of the target MBS broadcast and / or multicast service and improving the security and reliability of communications.

[0226] In the embodiment of the present disclosure, the first information (including the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information) enables each MBS broadcast and / or multicast service to be broadcast and / or multicast only in part of the MBS service areas rather than in all MBS service areas. In this way, the terminal device can listen to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information based on the correspondence, which can reduce interference and power consumption to the terminal device and improve the security and reliability of communication.

[0227] The present disclosure also provides a method for processing a multimedia broadcast multicast service (MBS) applied to a base station. Figure 3 illustrates a flowchart of a method for processing a multimedia broadcast multicast service (MBS) provided by an embodiment of the present disclosure. This method can be performed by a multimedia broadcast multicast service (MBS) processing device, which can be implemented using software and / or hardware and is generally integrated into a base station. Depending on the specific application scenario, a base station can be referred to as an access point, a device in an access network that communicates with wireless terminal devices over the air interface through one or more sectors, or other names.

[0228] As shown in FIG3 , the method includes:

[0229] S310: Acquire first information, where the first information includes: a correspondence between first MBS service area information and MBS broadcast and / or multicast information.

[0230] Specifically, for the understanding of the first information, please refer to the previous text and will not be repeated here.

[0231] In some embodiments, the first MBS service area information includes:

[0232] Indicates the center position and distance threshold of the range of the first MBS service area, or multiple reference positions;

[0233] or,

[0234] A beam identifier indicating the range of the first MBS service area;

[0235] or,

[0236] A mapped cell identifier representing the range of the first MBS service area.

[0237] In some embodiments, obtaining the first information includes: obtaining the first information from a core network and / or other base stations.

[0238] In other embodiments, obtaining the first information includes: obtaining second information from the core network and / or other base stations, wherein the second information includes: a correspondence between the second MBS service area information and the MBS broadcast and / or multicast information; and determining the first information based on the second information.

[0239] Specifically, there are various specific contents of the second MBS service area information, which are described below with reference to typical examples, but do not constitute a limitation to the present disclosure.

[0240] In one example, the second MBS service area information includes a geographical location identifier indicating the range of the second MBS service area. In this case, the second information may be used as the first information, but is not limited thereto.

[0241] In another example, the second MBS service area information includes a beam identifier indicating the range of the second MBS service area. In this case, the second information can be used as the first information. Of course, based on the correspondence between beam identifiers and geographic location area identifiers, the beam identifier in the second information can be replaced with the corresponding geographic location area identifier to obtain the first information. However, this is not limited to this.

[0242] In another example, the second MBS service area information includes a mapped cell identifier indicating the scope of the second MBS service area. In this case, the second information can be used as the first information. Of course, based on the correspondence between the mapped cell identifier and the geographic location area identifier, the mapped cell identifier in the second information can be replaced with the corresponding geographic location area identifier to obtain the first information. However, this is not limited to this.

[0243] S320. Send first information to the terminal device, where the first information is used to instruct the terminal device to listen to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information based on the corresponding relationship.

[0244] In some embodiments, the first information may be sent to the terminal device via a broadcast message, or a NAS message, or an RRC dedicated signaling.

[0245] In the embodiment of the present disclosure, the first information (including the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information) enables each MBS broadcast and / or multicast service to be broadcast and / or multicast only in part of the MBS service areas rather than in all MBS service areas. In this way, the terminal device can listen to the MBS broadcast and / or multicast service corresponding to the MBS broadcast and / or multicast information based on the correspondence, which can reduce interference and power consumption to the terminal device and improve the security and reliability of communication.

[0246] The multimedia broadcast multicast service MBS processing method provided by the embodiment of the present disclosure is described in detail below with reference to three detailed embodiments.

[0247] Example 1

[0248] Step 1.1: The base station obtains first information, wherein the first information includes a correspondence between first MBS service area information and MBS broadcast and / or multicast information, and the first MBS service area information includes a geographic location identifier, that is, the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information includes: a correspondence between a geographic area identifier representing the range of the first MBS service area and the MBS broadcast and / or multicast information, wherein the geographic area identifier includes: a center location, or a distance threshold from the center location, or multiple reference locations.

[0249] Of course, the first information may also include first MBS service area information, and may also include a target center position, or a target distance threshold, or multiple target reference positions.

[0250] Step 1.2: The base station sends first information to the terminal device.

[0251] The terminal device can receive the first information through a broadcast message, a NAS message, or an RRC dedicated signaling.

[0252] Step 1.3: The terminal device receives the first information sent by the base station.

[0253] The terminal device receives the first information sent by the base station, including: when it is determined that the terminal device meets the first condition, receiving the first information sent by the base station.

[0254] The first condition includes: the terminal device obtains indication information of supporting MBS broadcast and / or multicast services in the current serving cell, or the terminal device reselects to a new cell after performing cell reselection.

[0255] Step 1.4: Based on the corresponding relationship, determine the target center position and target distance threshold corresponding to the target MBS broadcast and / or multicast information to be received; when the distance between the terminal device's position and the target center position is less than the target distance threshold, listen to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information; or, based on the corresponding relationship, determine multiple target reference positions corresponding to the target MBS broadcast and / or multicast information to be received; when the terminal device's position is within a polygonal area formed by multiple target reference positions, listen to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information.

[0256] As described above, the first information may include the target center position, or the target distance threshold, or multiple target reference positions. In this case, the terminal device may extract the target center position, or the target distance threshold, or multiple target reference positions from the first information.

[0257] Example 2

[0258] Step 2.1: The base station obtains first information, wherein the first information includes a correspondence between first MBS service area information and MBS broadcast and / or multicast information, and the first MBS service area information includes a beam identifier, that is, the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information, including: a correspondence between the beam identifier representing the range of the first MBS service area and the MBS broadcast and / or multicast information.

[0259] Of course, the first information may also include a signal quality threshold for the beam corresponding to the beam identifier. The signal quality threshold corresponding to the beam identifier includes: a reference signal received power (RSRP) threshold, or a reference signal received quality (RSRQ) threshold, or a signal to interference plus noise ratio (SINR) threshold.

[0260] It should be noted that the signal quality thresholds corresponding to different beams may be the same or different.

[0261] Step 2.2: The base station sends first information to the terminal device.

[0262] Step 2.2 is similar to step 1.2 and will not be repeated here.

[0263] Step 2.3: The terminal device receives the first information sent by the base station.

[0264] Step 2.3 is similar to step 1.3 and will not be repeated here.

[0265] Step 2.4: Determine at least one target beam identifier corresponding to the target MBS broadcast and / or multicast information to be received based on the corresponding relationship; obtain the target signal quality threshold corresponding to the target beam identifier based on the first information; when the target beam signal quality corresponding to the target beam identifier is higher than the target signal quality threshold, listen to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information.

[0266] Of course, if there are multiple target beam identifiers, and the signal qualities of the multiple target beams corresponding to the multiple target beam identifiers are all higher than the corresponding target signal quality thresholds, the target beam with the highest signal quality is selected to listen to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information.

[0267] Example 3

[0268] Step 3.1: The base station obtains first information, wherein the first information includes a correspondence between first MBS service area information and MBS broadcast and / or multicast information, and the first MBS service area information includes a mapped cell identifier, that is, the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information, including: a correspondence between the mapped cell identifier representing the range of the first MBS service area and the MBS broadcast and / or multicast information.

[0269] Step 3.2: The base station sends first information to the terminal device.

[0270] Step 3.2 is similar to step 1.2 and will not be repeated here.

[0271] Step 3.3: The terminal device receives the first information sent by the base station.

[0272] Step 3.3 is similar to step 1.3 and will not be repeated here.

[0273] Step 3.4: Determine the target mapping cell identifier corresponding to the target MBS broadcast and / or multicast information to be received based on the corresponding relationship; when the current mapping cell identifier corresponding to the terminal device belongs to the target mapping cell identifier, listen to the target MBS broadcast and / or multicast service corresponding to the target MBS broadcast and / or multicast information.

[0274] In order to implement the above-mentioned multimedia broadcast multicast service MBS processing method, the embodiment of the present disclosure further provides a terminal device. For example, FIG4 is a schematic structural diagram of a terminal device provided by the embodiment of the present disclosure. Referring to FIG4 , the terminal device includes:

[0275] The memory 420 is used to store computer programs; the transceiver 410 is used to send and receive data under the control of the processor 400; the processor 400 is used to read the computer program in the memory 420 and perform the following operations:

[0276] receiving first information sent by a base station, wherein the first information includes: a correspondence between first MBS service area information and MBS broadcast and / or multicast information;

[0277] MBS broadcast and / or multicast services corresponding to the MBS broadcast and / or multicast information are monitored based on the corresponding relationship.

[0278] The transceiver 410 is configured to receive and send data under the control of the processor 400 .

[0279] In FIG4 , the bus architecture may include any number of interconnected buses and bridges, specifically one or more processors 400 represented by processor 400 and various circuits of memory 420 represented by memory 420, linked together. The bus architecture may also link together various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and are therefore not further described herein. The bus interface provides an interface. The transceiver 410 may be a plurality of components, i.e., a transmitter and a receiver, providing a unit for communicating with various other devices on a transmission medium, such as a wireless channel, a wired channel, an optical cable, and the like. The processor 400 is responsible for managing the bus architecture and general processing, and the memory 420 may store data used by the processor 400 when performing operations.

[0280] The processor 400 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or a complex programmable logic device (CPLD). The processor 400 may also adopt a multi-core architecture.

[0281] In some embodiments, receiving first information sent by a base station includes:

[0282] When it is determined that the terminal device meets the first condition, first information sent by the base station is received, where the first condition includes:

[0283] The terminal device obtains indication information of supporting MBS broadcast and / or multicast services in the current serving cell;

[0284] or,

[0285] The terminal device performs cell reselection and then reselects to a new cell.

[0286] In some embodiments, the correspondence between the first MBS service area information and the MBS broadcast and / or multicast information includes:

[0287] One first MBS service area information corresponds to one MBS broadcast and / or multicast information;

[0288] or,

[0289] One first MBS service area information corresponds to multiple MBS broadcast and / or multicast information;
