DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0064] In order to better understand the paging method according to the embodiment of the present disclosure, the following first describes a communication system to which the embodiment of the present disclosure is applied.

[0065] As shown in FIG. 1, FIG. 1 is a schematic diagram of an architecture of a communication system 10 according to an embodiment of the present disclosure. The communication system 10 may include, but is not limited to, one network device 11 and one terminal device 12. The number and form of devices shown in FIG. 1 are used for example only, but do not constitute limitations on the embodiment of the present disclosure, and in actual application, the communication system 10 may include two or more network devices 11 and two or more terminal devices 12. The communication system 10 shown in FIG. 1 is exemplified as including one network device 11 and one terminal device 12.

[0066] It should be noted that the technical solutions of the embodiments of the present disclosure may be used in various communication systems, such as a long term evolution (LTE) system, a 5th generation (5G) mobile communication system, a 5G new radio (NR) system, or other future new mobile communication systems.

[0067] The network device 11 in the embodiment of the present disclosure is a network-side entity for transmitting or receiving a signal. For example, the network device 11 may be an evolved base station (eNB), a transmission reception point (TRP), a next generation base station (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiment of the present disclosure does not limit the specific technology and the specific device form adopted in the network device. The network device according to the embodiment of the present disclosure may be configured by a central unit (CU) and a distributed unit (DU), where the CU may be called a control unit. When a CU-DU structure is adopted, the protocol layer of the network device, for example, a base station, may be separated, and some protocol layer functions may be centrally controlled by the CU, and some or all of the remaining protocol layer functions may be distributed to the DU, and the DU may be centrally controlled by the CU.

[0068] The terminal device 12 in the embodiment of the present disclosure is a user-side entity for receiving or transmitting signals, such as a mobile phone. The terminal device may be called a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device may be an automobile with a communication function, a smart automobile, a mobile phone, a wearable device, a tablet computer (Pad), a computer with a wireless transmission and reception function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of the present disclosure are not limited to a specific technology adopted in a terminal device and a specific device form.

[0069] As can be understood, the communication system described in the embodiments of the present disclosure is intended to more clearly explain the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions of the embodiments of the present disclosure; as those skilled in the art can appreciate, with the evolution of system architecture and the emergence of new service scenarios, the technical solutions of the embodiments of the present disclosure are equally applicable to similar technical issues.

[0070] Currently, the configuration and transmission methods of MBS services include that the MBMS service or MBS services are marked with an MBS service identifier, which is TMGI (Temporary Mobile Group Identity) or MBS Session ID or MBS QoS flow ID.

[0071] Here, there are two kinds of transmission modes of MBS service, the first kind is multicast transmission: the terminal device enters RRC (Radio Resource Control) connected state (CONNECTED) and receives the transmission setting information of MBS service, so that the MBS service can be received. The network side device transmits the reception setting information of MBS service to the terminal device through the terminal device's specific signaling.

[0072] The second type is broadcast transmission: a terminal device can receive the transmission setting information of the MBS service and receive the MBS service in a radio resource control idle state (IDLE), a radio resource control inactive state (INACTIVE), or a radio resource control connected state (CONNECTED). A network side device transmits the reception setting information of the MBS service to a terminal device by system information such as SIB (System Information Block) and MBS control channel information such as MCCH (Multicast Control Channel).

[0073] The paging method includes a network side device notifying a terminal device of the arrival of a service through a radio resource control (RRC) paging message (Paging), and the Paging message includes an identifier of the terminal device. The terminal device calculates a Paging time position that needs to be monitored in each paging cycle based on its own identifier according to a paging cycle set by the network side device. When the terminal device is in a radio resource control idle state (IDLE) or a radio resource control inactive state (INACTIVE), the terminal device initiates a connection establishment process after receiving a paging message for itself.

[0074] Here, the paging message is scheduled and transmitted to the terminal device by a PDCCH (Physical Downlink Control Channel) channel identified by a P-RNTI (Paging Radio Network Temporary Identity).

[0075] However, when a network side device activates a specific MBS service, the network side device can inform the terminal device that a specific MBS service is activated by carrying a session identifier MBS Session ID of the MBS service in a paging message. However, what resources the network side device uses to send this paging message carrying the session identifier of the MBS service, how the terminal device monitors this paging message, and what specific actions the terminal device should take after receiving this paging message are all problems that need to be solved immediately.

[0076] Based on this, an embodiment of the present disclosure provides a paging method and apparatus, which sets a specific paging resource for a paging message carrying MBS service information, and only when a terminal device is interested in an MBS service, monitors the paging message on the specific paging resource, and after receiving the paging message, determines whether to initiate a connection establishment or recovery process based on the MBS service it is interested in, so as to realize rapid activation of the MBS service and realize power saving of the terminal device.

[0077] The paging method and apparatus according to the present disclosure will be introduced in detail below in conjunction with the accompanying drawings.

[0078] Referring to FIG. 2, FIG. 2 is a schematic flowchart of a paging method performed by a terminal device according to an embodiment of the present disclosure, and as shown in FIG. 2, the method may include, but is not limited to, the following steps S1 to S2.

[0079] S1 responds to receipt of Multicast Broadcast Service (MBS) paging message configuration information.

[0080] In an embodiment of the present disclosure, the Multicast Broadcast Service (MBS) paging message configuration information includes a resource configuration of the MBS paging message, where the resource configuration of the MBS paging message is a specific configuration for transmitting the MBS paging message. As can be understood, information such as a location where the MBS paging message is delivered can be determined based on the resource configuration of the MBS paging message.

[0081] In some embodiments, the MBS paging message configuration information includes one or more sets of MBS paging message resource configurations, where the one or more sets of MBS paging message resource configurations may correspond to one or more MBS services.

[0082] In S2, it is determined based on the MBS paging message setting information whether or not to receive an MBS paging message, which is a paging message carrying MBS service information.

[0083] As can be seen, during paging, the terminal device determines whether there is an MBS service of interest to the terminal device based on the resource configuration of the MBS paging message in the MBS paging message configuration information, and if there is an MBS service of interest to the terminal device, the terminal device receives the MBS paging message.

[0084] In an embodiment of the present disclosure, in response to receiving the multicast broadcast service (MBS) paging message configuration information, the terminal device determines whether to receive an MBS paging message, which is a paging message carrying MBS service information, based on the MBS paging message configuration information. In an embodiment of the present disclosure, the multicast broadcast service (MBS) paging message configuration information is provided to the terminal device, and the terminal device can determine whether to receive an MBS paging message based on the MBS paging message configuration information, so that if the terminal device is interested in the MBS service, it can receive the MBS paging message to realize rapid activation of the MBS service and realize better power saving of the terminal device.

[0085] In some embodiments, the step of responding to receipt of the MBS paging message configuration information includes responding to receipt of MBS paging message configuration information defined by a protocol or responding to receipt of MBS paging message configuration information provided by a network side device.

[0086] In the embodiments of the present disclosure, the MBS paging message setting information may be specified by a protocol, provided by a network side device, or in any other feasible manner, and the present disclosure is not specifically limited in this regard.

[0090] Here, the time domain configuration of the control channel and data channel of the MBS paging message is, for example, a paging search space pagingSearchSpace of a PDCCH (Physical Downlink Control Channel) that schedules the MBS service paging message. If the paging search space pagingSearchSpace of the PDCCH that schedules the MBS service paging message is not additionally configured, the paging search space pagingSearchSpace of the P-RNTI PDCCH may be adopted by default.

[0091] The frequency domain configuration of the control channel and data channel of the MBS paging message is, for example, a CORESET (Control Resource Set) of a PDCCH for scheduling the MBS service paging message. If the CORESET of the PDCCH for scheduling the MBS service paging message is not additionally configured, the CORESET of the P-RNTI PDCCH may be adopted by default.

[0092] The identifier of the MBS paging message is illustratively an identifier of a PDCCH for scheduling the MBS paging message, for example, an MBS identifier identified by a P-RNTI is adopted. If the identifier of a PDCCH for scheduling the MBS service paging message is not set, the identifier of the PDCCH identified by the P-RNTI may be adopted by default.

[0093] The paging period of the MBS paging message is illustratively a paging period, illustratively 50 ms, 100 ms, 200 ms, etc.

[0094] The start offset amount of the MBS paging message is, for example, the start monitoring position of each period of the MBS paging message. It may be calculated by the formula mbs-StartOffset=[(SFN×10)+subframe_number] modulo(mbs-PagingCycle).

[0095] Here, SFN is the system frame number, subframe_number is the subframe number and / or slot number and / or OFDM (Orthogonal Frequency Division Multiplexing) symbol number, mbs-PagingCycle is the paging cycle of the MBS paging message, and mbs-StartOffset is the start position offset of the MBS paging message.

[0096] The control channel resource or data channel resource of the MBS paging message has an associated relationship with the downlink beam, and the data channel resource is illustratively a PDSCH (Physical Downlink Shared Channel) resource.

[0097] In some embodiments, the MBS paging message configuration information further includes an MBS service identifier corresponding to the resource configuration of the MBS paging message, where the MBS service identifier includes a Temporary Mobility Group Identifier (TMGI) or an MBS session identifier or an MBS service flow identifier.

[0098] In some embodiments, the downlink beam is marked with a Synchronous Signal Block (SSB) identifier or a Channel State Information Reference Signal (CSI-RS) identifier.

[0099] In some embodiments, the association relationship between the control channel resource or data channel resource of the MBS paging message and the downlink beam includes an association relationship between one or more control channel resources or one or more data channel resources of the MBS paging message and the downlink beam for each paging period of the MBS paging message.

[0100] In an embodiment of the present disclosure, for each paging period of the MBS paging message, the control channel resources of the N MBS paging messages may be numbered based on time-frequency locations and the M downlink beams may be numbered, and the control channel resources of the N MBS paging messages may be assigned to the M downlink beams in an interleaved manner in numerical order, or the control channel resources of the N MBS paging messages may be assigned to the M downlink beams in numerical order consecutively, where the numbering based on time-frequency locations includes numbering based on time domain locations or numbering based on frequency domain locations.

[0101] In an exemplary embodiment, when N is 8 and M is 4, that is, in a paging period of one MBS paging message, the control channel resources of the eight MBS paging messages are numbered based on the time-frequency positions, and the four downlink beams are numbered. The control channel resources of the eight MBS paging messages may be assigned to the four downlink beams in the order of their numbers in an interleaved manner, or the control channel resources of the eight MBS paging messages may be assigned to the four downlink beams in the order of their numbers in a consecutive manner.

[0102] Here, the control channel resources of the eight MBS paging messages are interleaved and assigned to the four downlink beams in numerical order, e.g., the control channel resources of the MBS paging messages numbered 1 and 5 correspond to downlink beam 1, the control channel resources of the MBS paging messages numbered 2 and 6 correspond to downlink beam 2, the control channel resources of the MBS paging messages numbered 3 and 7 correspond to downlink beam 3, and the control channel resources of the MBS paging messages numbered 4 and 8 correspond to downlink beam 4.

[0103] Here, the control channel resources of the eight MBS paging messages are consecutively assigned to the four downlink beams in numerical order, e.g., the control channel resources of the MBS paging messages numbered 1 and 2 correspond to downlink beam 1, the control channel resources of the MBS paging messages numbered 3 and 4 correspond to downlink beam 2, the control channel resources of the MBS paging messages numbered 5 and 6 correspond to downlink beam 3, and the control channel resources of the MBS paging messages numbered 7 and 8 correspond to downlink beam 4.

[0104] In an embodiment of the present disclosure, in a paging period of one MBS paging message, the N data channel resources may be numbered based on time-frequency locations and the M downlink beams may be numbered, and the N data channel resources may be assigned to the M downlink beams in numerical order in an interleaved manner, or the N data channel resources may be assigned to the M downlink beams in numerical order in a consecutive manner, where the numbering based on time-frequency locations includes numbering based on time domain locations or numbering based on frequency domain locations.

[0105] In an exemplary embodiment, when N is 8 and M is 4, i.e., in a paging period of one MBS paging message, the eight data channel resources are numbered based on the time-frequency positions, and the four downlink beams are numbered. The eight data channel resources may be assigned to the four downlink beams in the order of their numbers in an interleaved manner, or the eight data channel resources may be assigned to the four downlink beams in the order of their numbers in a consecutive manner.

[0106] Here, the eight data channel resources are interleaved and assigned to the four downlink beams in numerical order, e.g., data channel resources numbered 1 and 5 correspond to downlink beam 1, data channel resources numbered 2 and 6 correspond to downlink beam 2, data channel resources numbered 3 and 7 correspond to downlink beam 3, and data channel resources numbered 4 and 8 correspond to downlink beam 4.

[0107] Here, the allocation of the eight data channel resources consecutively to the four downlink beams in numerical order may, for example, be such that data channel resources numbered 1 and 2 correspond to downlink beam 1, data channel resources numbered 3 and 4 correspond to downlink beam 2, data channel resources numbered 5 and 6 correspond to downlink beam 3, and data channel resources numbered 7 and 8 correspond to downlink beam 4.

[0108] In some embodiments, when a set of MBS paging message resources configures multiple MBS services, the multiple MBS paging message resources in the set of MBS paging message resource configuration may be assigned to different MBS services respectively. Illustratively, in one MBS paging cycle, there are two PDCCH resources, where PDCCH resource-1 is assigned to MBS service-1, and PDCCH resource-2 is assigned to MBS service-2.

[0109] In some embodiments, the MBS service information includes an MBS service identifier or an MBS service label.

[0110] Here, the MBS service identifier includes a Temporary Mobility Group Identifier (TMGI) or an MBS session identifier or an MBS service flow identifier.

[0111] The MBS service label includes a system message or a USD (User Service Description) file is provided with an MBS service list, and each item in the MBS service list corresponds to one MBS service, and the MBS service list item label corresponds to the MBS service label. For example, if the MBS service list has four MBS services -1 / -2 / -3 / -4, and the list items are marked as list items -1 / -2 / -3 / -4 in order, the list item -1 / -2 / -3 / -4 labels correspond to MBS services -1 / -2 / -3 / -4, respectively.

[0112] As shown in FIG. 3, after step S1 of responding to receiving Multicast Broadcast Service (MBS) paging message configuration information, the paging method provided in the embodiment of the present disclosure further includes step S3 of determining whether to monitor the transmission of an MBS paging message based on the MBS paging message configuration information.

[0113] Exemplarily, after receiving the MBS paging message configuration information, the terminal device monitors the scheduling information corresponding to the MBS paging message on the PDCCH resource corresponding to the resource configuration of the MBS paging message at a paging period of 100 ms.

[0114] In some embodiments, the step of determining whether to monitor transmission of an MBS paging message based on the MBS paging message configuration information includes the step of not monitoring the transmission of the MBS paging message or stopping monitoring the transmission of the MBS paging message if the RRC connection state is a radio resource control connected state (CONNECTED), or the currently serving cell does not provide an MBS service, or the currently serving cell does not provide an MBS service of interest to the terminal device, and the step of monitoring the transmission of the MBS paging message or starting monitoring the transmission of the MBS paging message if the RRC connection state is a radio resource control idle state (IDLE) or a radio resource control inactive state (INACTIVE), or the currently serving cell provides an MBS service, or the currently serving cell provides an MBS service of interest to the terminal device.

[0115] Here, the fact that the currently serving cell does not provide the MBS service includes that the currently serving cell of the terminal device is not provided with system information corresponding to the MBS. For example, the fact that the currently serving cell does not provide the MBS service of interest to the terminal device indicates that the currently serving cell provides MBS service-1 in the system information of the currently serving cell, but the terminal device is interested in MBS service-2.

[0116] In some embodiments, the MBS services of interest to the terminal device include MBS services marked with MBS service identifiers of interest to the terminal device provided in a user service description (USD) file, or MBS services for which an MBS session has been established, or MBS services that the terminal device has added to a data transmission group.

[0117] Here, the MBS service marked by the MBS service identifier of interest of the terminal device provided in the User Service Description (USD) file, illustratively indicates in the USD that the TMGI-1 (Temporary Mobile Group Identity) or the MBS session ID-1 (MBS session identifier) ​​is an MBS service of interest to the terminal device.

[0118] For an MBS service with an established MBS session, illustratively, MBS service-1 has already established a corresponding MBS session. As can be seen, MBS service-1 with an established MBS session indicates that the terminal device is already using the same type of MBS service-1, and the terminal device should also be interested in this MBS service-1.

[0119] In the case of an MBS service that a terminal device has added to a data transmission group, for example, the terminal device has negotiated through a non-access stratum (NAS) message to add MBS service-1 to the data transmission group. As can be seen, a user in the data transmission group is notified by broadcast what programs will be broadcast, and the terminal device has already negotiated through a NAS message to add MBS service-1 to the data transmission group, which indirectly indicates that the terminal device is interested in MBS service-1 in this data transmission group.

[0120] In some embodiments, the step of determining whether to monitor the transmission of the MBS paging message based on the MBS paging message setting information further includes a step of selecting one resource position in a paging period of one MBS paging message and monitoring the transmission of the MBS paging message when the resource setting of the MBS paging message includes an association relationship between a control channel resource or a data channel resource of the MBS paging message and a downlink beam.

[0121] In some embodiments, the step of selecting one resource location for each paging period of the MBS paging message and monitoring the transmission of the MBS paging message includes the step of selecting, for each paging period of the MBS paging message, to monitor the transmission of the MBS paging message if the measurement result of the beam is higher than a threshold or if the beam is a designated beam for receiving the paging message.

[0122] Here, the beam is a designated beam for receiving the paging message. For example, in one paging period, there are four control channel resources or data channel resources for MBS paging messages, corresponding to four beams respectively. When the network side device designates the terminal device to receive the paging message on beam-1, the terminal device selects to receive the paging message on beam-1 based on the designation of the network side device.

[0123] As shown in FIG. 4, the paging method provided in the embodiment of the present disclosure further includes: S2: if it is determined based on the MBS paging message setting information to receive an MBS paging message, execute S41: start MBS service reception.

[0124] In some embodiments, initiating the MBS service reception includes initiating a connection access process or receiving the corresponding MBS service based on a resource configuration in the MBS paging message.

[0125] In some embodiments, initiating the connection access process includes providing indication information by the terminal device to indicate that reception of the MBS service is required.

[0126] In an embodiment of the present disclosure, a terminal device receives an MBS paging message and initiates MBS service reception, and the terminal device initiates a connection access process, where the MBS service information carried in the MBS paging message includes an MBS service of interest to the terminal device, and the terminal device provides indication information to indicate that it is necessary to receive the MBS service.

[0127] Here, the instruction information may include at least one of the following:

[0128] 1) The reason for connection access is the need to receive an MBS service, and illustratively, in the RRCSetuRequest or RRCResumeRequest message, the cause value is indicated to be MT-MBS (Mobile Terminated-MBS, mobile terminal MBS) (i.e., for a connection establishment process initiated by receiving MBS paging).

[0129] 2) MBS service information, illustratively the MBS service information includes an MBS service identifier or an MBS service label.

[0130] Here, the MBS service identifier includes a Temporary Mobility Group Identifier (TMGI) or an MBS session identifier or an MBS service flow identifier.

[0131] The MBS service label includes a system message or a USD (User Service Description) file is provided with an MBS service list, and if each item in the MBS service list corresponds to one MBS service, the MBS service list item label corresponds to the MBS service label. For example, if the MBS service list has four MBS services -1 / -2 / -3 / -4, and the list items are marked as list items -1 / -2 / -3 / -4 in order, the list item -1 / -2 / -3 / -4 labels correspond to MBS services -1 / -2 / -3 / -4, respectively.

[0132] In some embodiments, initiating a connection access process includes initiating a connection establishment process or initiating a connection restoration process.

[0133] Here, in the embodiment of the present disclosure, initiating the connection establishment process includes, for a terminal device in an IDLE state, when the mode of the MBS service is a first transmission mode, the terminal device can receive the MBS service by entering an RRC (Radio Resource Control) connected state (CONNECTED) and receiving transmission setting information of the MBS service. The network side device transmits the reception setting information of the MBS service to the terminal device through the terminal device's specific signaling, in which case the terminal device initiates the connection establishment process. Specifically, initiating the connection process illustratively includes transmitting an RRC interface request SetupRequest message.

[0134] In the embodiment of the present disclosure, initiating the connection recovery process includes, for a terminal device in an INACTIVE state, when the mode of the MBS service is a first transmission mode, the terminal device can receive the MBS service by entering an RRC (Radio Resource Control) connected state (CONNECTED) and receiving transmission setting information of the MBS service. When the network side device sends the reception setting information of the MBS service to the terminal device through the terminal device's specific signaling, the terminal device initiates the connection recovery process. Specifically, initiating the connection recovery process illustratively includes sending an RRC recovery request ResumeRequest message.

[0135] Here, the step of receiving the corresponding MBS service based on the resource configuration of the MBS paging message includes: when the mode of the MBS service is a second broadcast transmission, the terminal device can receive transmission configuration information of the MBS service in a radio resource control idle state (IDLE), a radio resource control inactive state (INACTIVE), or a radio resource control connected state (CONNECTED), and receive the MBS service. When the network side device transmits reception configuration information of the MBS service to the terminal device through system information such as a SIB (System Information Block) and MBS control channel information such as a MCCH (Multicast Control Channel), the terminal device receives the resource configuration of the MBS paging message and receives the corresponding MBS service according to the resource configuration of the MBS paging message.

[0136] In some embodiments, the MBS paging message configuration information includes an MBS access control parameter, and wherein the step of initiating MBS service reception includes a step of determining whether to initiate a connection access process in response to receiving the MBS access control parameter.

[0137] In some embodiments, the MBS access control parameters include at least one of a specific access identifier or access type corresponding to the MBS service, an access randomization parameter for the MBS service, and a time setting for access prohibition after determining that an access attempt is prohibited from initiating.

[0138] Here, the specific access identifier or access type corresponding to the MBS service includes an access identifier ID: Access Identity-1 or an access type: Access Category-1, and this specific access identifier or access type is barred in the current serving cell, for example, if barred, the terminal device will not initiate an access request.

[0139] In some embodiments, the access randomization parameters for the MBS service include a random number interval value within which access is permitted.

[0140] Here, the random number interval value for which access is permitted is illustratively a random parameter range of [0, 1], and a random parameter range for which access is permitted is [0, 0.5]. Then, the terminal device adopts a uniform distribution method between [0, 1] to obtain a random parameter, and if the random parameter belongs to [0, 0.5], the terminal device can initiate an access attempt.

[0141] In some embodiments, the duration setting for the ban includes a ban timer duration or a ban timer randomization value scaling parameter.

[0142] Here, the time length of the access prohibition timer in the embodiment of the present disclosure. As can be seen, by accessing the timer and setting the corresponding time length, it is possible to prohibit re-access within the corresponding time length after determining that the initiation of an access attempt is prohibited.

[0143] In the embodiment of the present disclosure, the randomization value scaling parameter of the access prohibition timer is illustratively as follows: after the terminal device determines that the MBS service is access-prohibited, if the MBS service access prohibition timer needs to be started, the terminal device will not initiate an access request during the timer execution period. Here, if the time length of the access prohibition timer set by the network side device is a, the terminal device adopts a uniform distribution method between [0, 1] to obtain a random number X, and the scaling parameter of the random number X is b (wherein the value of b can be "1", i.e., no additional scaling is performed on the random number X), which is set by the network side or specified by the protocol, the final random value is bX, and the terminal device determines that the time length setting y of the access prohibition is calculated based on a and bX.

[0144] Referring again to FIG. 4, the paging method according to an embodiment of the present disclosure further includes a step of performing S42: not starting MBS service reception, including not starting a connection access process, if it is determined based on the MBS paging message setting information that the MBS paging message will not be received.

[0145] In some embodiments, not initiating the connection access process includes not transmitting a Radio Resource Control (RRC) message corresponding to the access request or not transmitting random access request information.

[0146] Wherein, if a Radio Resource Control (RRC) message corresponding to the access request is not sent, the Radio Resource Control (RRC) message includes a connection establishment request message or a connection recovery request message.

[0147] Not sending random access request information, for example, refers to not sending the first random access response information Msg1 in a four-stage random access process, or not sending the second random access response information MsgB in a two-stage random access process.

[0148] In some embodiments, the step of determining whether to receive an MBS paging message based on the MBS paging message configuration information includes the step of not receiving the MBS paging message if the radio resource control (RRC) connection state is a radio resource control connected state (CONNECTED), or the currently serving cell does not provide an MBS service, or the currently serving cell does not provide an MBS service of interest to the terminal device, and the step of receiving the MBS paging message if the radio resource control (RRC) connection state is a radio resource control idle state (IDLE) or a radio resource control inactive state (INACTIVE), or the currently serving cell provides an MBS service, or the currently serving cell provides an MBS service of interest to the terminal device.

[0149] FIG. 5 is a schematic flowchart of another paging method performed by a network side device according to an embodiment of the present disclosure. As shown in FIG. 5, the method may include, but is not limited to, the following steps S10 to S20.

[0150] In S10, the process responds with transmission of Multicast Broadcast Service (MBS) paging message setting information.

[0151] In an embodiment of the present disclosure, the Multicast Broadcast Service (MBS) paging message configuration information includes a resource configuration of the MBS paging message, where the resource configuration of the MBS paging message is a specific configuration for transmitting the MBS paging message. As can be understood, information such as a location where the MBS paging message is delivered can be determined based on the resource configuration of the MBS paging message.

[0152] In some embodiments, the MBS paging message configuration information includes one or more sets of MBS paging message resource configurations, where the one or more sets of MBS paging message resource configurations may correspond to one or more MBS services.

[0153] In S20, based on the MBS paging message configuration information, an MBS paging message is transmitted, which is a paging message carrying MBS service information.

[0154] As can be seen, during paging, the terminal device determines whether there is an MBS service of interest to the terminal device based on the resource configuration of the MBS paging message in the MBS paging message configuration information, and if there is an MBS service of interest to the terminal device, the terminal device receives the MBS paging message.

[0155] In an embodiment of the present disclosure, in response to the transmission of multicast broadcast service (MBS) paging message configuration information by the network side device, a MBS paging message is transmitted, which is a paging message carrying MBS service information, based on the MBS paging message configuration information. In an embodiment of the present disclosure, in response to the transmission of multicast broadcast service (MBS) paging message configuration information by the network side device, the multicast broadcast service (MBS) paging message configuration information is provided to the terminal device, and the terminal device determines whether to receive the MBS paging message based on the MBS paging message configuration information, thereby realizing the reception of the MBS paging message when the terminal device is interested in the MBS service, and realizing the rapid activation of the MBS service and better power saving of the terminal device.

[0156] In some embodiments, the step of responding to the transmission of the MBS paging message configuration information includes responding to the transmission of MBS paging message configuration information defined by a protocol or responding to the transmission of configured MBS paging message configuration information.

[0157] In the embodiments of the present disclosure, the MBS paging message setting information may be specified by a protocol, provided by a network side device, or in any other feasible manner, and the present disclosure is not specifically limited in this regard.

[0158] In some embodiments, the step of responding to the transmission of the configured MBS paging message configuration information includes the step of responding to the transmission of the MBS paging message configuration information configured by system information or MBS control channel information or an RRC connection release message.

[0160] In some embodiments, the MBS paging message configuration information includes a resource configuration for the MBS paging message, where the resource configuration for the MBS paging message includes at least one of a control channel for the MBS paging message, a time domain configuration for the data channel, a frequency domain configuration for the data channel, an identifier for the MBS paging message, a paging period for the MBS paging message, a starting offset amount for the MBS paging message, and an associated relationship between the control channel resource or the data channel resource for the MBS paging message and the downlink beam.

[0161] Here, the time domain setting of the control channel and data channel of the MBS paging message is, for example, a paging search space pagingSearchSpace of a PDCCH (Physical Downlink Control Channel) for scheduling the MBS service paging message. If the paging search space pagingSearchSpace of the PDCCH for scheduling the MBS service paging message is not set, the paging search space pagingSearchSpace of the P-RNTI PDCCH may be adopted by default.

[0162] The frequency domain configuration of the control channel and data channel of the MBS paging message is, for example, a CORESET (Control Resource Set) of a PDCCH for scheduling the MBS service paging message. If the CORESET of the PDCCH for scheduling the MBS service paging message is not configured, the CORESET of the P-RNTI PDCCH may be adopted by default.

[0163] The identifier of the MBS paging message is illustratively an identifier of a PDCCH for scheduling the MBS paging message, for example, an MBS identifier identified by a P-RNTI is adopted. If the identifier of a PDCCH for scheduling the MBS service paging message is not set, the identifier of the PDCCH identified by the P-RNTI may be adopted by default.

[0164] The paging period of the MBS paging message is illustratively a paging period, illustratively 50 ms, 100 ms, 200 ms, etc.

[0165] The start offset amount of the MBS paging message is, for example, the start monitoring position of each period of the MBS paging message. It may be calculated by the formula mbs-StartOffset=[(SFN×10)+subframe_number] modulo(mbs-PagingCycle).

[0166] Here, SFN is the system frame number, subframe_number is the subframe number and / or slot number and / or OFDM (Orthogonal Frequency Division Multiplexing) symbol number, mbs-PagingCycle is the paging cycle of the MBS paging message, and mbs-StartOffset is the start position offset of the MBS paging message.

[0167] The control channel resource or data channel resource of the MBS paging message has an associated relationship with the downlink beam, and the data channel resource is illustratively a PDSCH (Physical Downlink Shared Channel) resource.

[0168] In some embodiments, the MBS paging message configuration information further includes an MBS service identifier corresponding to the resource configuration of the MBS paging message, where the MBS service identifier includes a Temporary Mobility Group Identifier (TMGI) or an MBS session identifier or an MBS service flow identifier.

[0169] In some embodiments, the downlink beam is marked with a synchronization signal block identifier or a channel state information reference signal identifier.

[0170] In some embodiments, the association relationship between the control channel resource or data channel resource of the MBS paging message and the downlink beam includes an association relationship between one or more control channel resources or one or more data channel resources of the MBS paging message and the downlink beam for each paging period of the MBS paging message.

[0172] In an exemplary embodiment, when N is 8 and M is 4, that is, in a paging period of one MBS paging message, the control channel resources of the eight MBS paging messages are numbered based on the time-frequency positions, and the four downlink beams are numbered. The control channel resources of the eight MBS paging messages may be assigned to the four downlink beams in the order of their numbers in an interleaved manner, or the control channel resources of the eight MBS paging messages may be assigned to the four downlink beams in the order of their numbers in a consecutive manner.

The eight data channel resources may be assigned to the four downlink beams in the order of their numbers in an interleaved manner, or the eight data channel resources may be assigned to the four downlink beams in the order of their numbers in a consecutive manner.

Illustratively, in one MBS paging cycle, there are two PDCCH resources, where PDCCH resource-1 is assigned to MBS service-1, and PDCCH resource-2 is assigned to MBS service-2.

[0180] In some embodiments, the MBS service information includes an MBS service identifier or an MBS service label.

[0182] The MBS service label includes a system message or a USD (User Service Description) file is provided with an MBS service list, and each item in the MBS service list corresponds to one MBS service, and the MBS service list item label corresponds to the MBS service label. For example, if the MBS service list has four MBS services -1 / -2 / -3 / -4, and the list items are marked as list items -1 / -2 / -3 / -4 in order, the list item -1 / -2 / -3 / -4 labels correspond to MBS services -1 / -2 / -3 / -4, respectively.

[0183] As shown in FIG. 6, in an embodiment of the present disclosure, the MBS paging message setting information includes an MBS access control parameter, where S20: after sending an MBS paging message based on the MBS paging message setting information, S30: executes controlling whether the terminal device initiates a connection access process based on the MBS access control parameter.

[0184] In some embodiments, controlling the terminal device to initiate a connection access process includes controlling the terminal device to provide indication information indicating that reception of the MBS service is required.

[0185] In the embodiment of the present disclosure, the terminal device is controlled to initiate a connection access process, and the terminal device is controlled to provide indication information indicating that it is necessary to receive the MBS service.

[0186] Here, the instruction information may include at least one of the following:

[0187] 1) The reason for connection access is the need to receive an MBS service, and illustratively, in the RRCSetuRequest or RRCResumeRequest message, the cause value is indicated to be MT-MBS (Mobile Terminated-MBS, mobile terminal MBS) (i.e., for a connection establishment process initiated by receiving MBS paging).

[0189] Here, the MBS service identifier includes a Temporary Mobility Group Identifier (TMGI) or an MBS session identifier or an MBS service flow identifier.

[0190] The MBS service label includes a system message or a USD (User Service Description) file is provided with an MBS service list, and if each item in the MBS service list corresponds to one MBS service, the MBS service list item label corresponds to the MBS service label.

[0194] Here, the random number interval value for which access is permitted is illustratively a random parameter range of [0, 1], and a random parameter range for which access is permitted is [0, 0.5]. Then, the terminal device adopts a uniform distribution method between [0, 1] to obtain a random parameter, and if the random parameter belongs to [0, 0.5], the terminal device can initiate an access attempt.

[0195] In some embodiments, the duration setting for the ban includes a ban timer duration or a ban timer randomization value scaling parameter.

[0196] Here, the time length of the access prohibition timer in the embodiment of the present disclosure. As can be seen, by accessing the timer and setting the corresponding time length, it is possible to prohibit re-access within the corresponding time length after determining that the initiation of an access attempt is prohibited.

[0197] In the embodiment of the present disclosure, the randomization value scaling parameter of the access prohibition timer is illustratively as follows: after the terminal device determines that the MBS service is access-prohibited, if the MBS service access prohibition timer needs to be started, the terminal device will not initiate an access request during the timer execution period. Here, if the time length of the access prohibition timer set by the network side device is a, the terminal device adopts a uniform distribution method between [0, 1] to obtain a random number X, and the scaling parameter of the random number X is b (wherein the value of b can be "1", i.e., no additional scaling is performed on the random number X), which is set by the network side or specified by the protocol, the final random value is bX, and the terminal device determines that the time length setting y of the access prohibition is calculated based on a and bX.

[0198] In some embodiments, when the terminal device is controlled not to initiate a connection access process based on the MBS access control parameters, it does not send a radio resource control (RRC) message corresponding to the access request or does not send random access request information.

[0199] Wherein, when not sending a Radio Resource Control (RRC) message corresponding to the access request, the Radio Resource Control (RRC) message includes a connection establishment request message or a connection recovery request message.

[0200] Not sending random access request information, for example, refers to not sending the first random access response information Msg1 in a four-stage random access process, or not sending the second random access response information MsgB in a two-stage random access process.
