Detailed disclosure of the present invention

[074] To better understand the paging method proposed in accordance with embodiments of the present disclosure, a communication system in which embodiments of the present disclosure can be applied is first described below.

[075] Fig. 1 shows a diagram of the architecture of a communication system 10 proposed according to embodiments of the present disclosure. The communication system 10 may include, among other things, a network device 11 and a terminal 12. The number and type of devices shown in Fig. 1 are used only as an example, and no limitation is imposed on the embodiments of the present disclosure. The communication system in practical implementations may include two or more network devices 11 and two or more terminals 12. As an example for illustration, the communication system shown in Fig. 1 includes a network device 11 and a terminal 12.

[076] It should be noted that the technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as a Long Term Evolution (LTE) communication system, a fifth generation (5G) mobile communication system, a 5G new radio (NR) system, or any other new mobile communication systems in the future.

[077] The network device 11 according to the embodiments of the present disclosure is a network side entity for transmitting or receiving signals. For example, the network device 11 may be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation base station (gNB) in the NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present disclosure do not limit the specific technology and the specific type of device used as the network device. The network device proposed according to the embodiments of the present invention may be composed of a central unit (CU) and distributed units (DU). The central unit CU may also be called a control unit. The use of the CU-DU structure allows the protocol layer of a network device, such as a base station, to be divided so that some of the protocol layer functions are centrally managed in the CU, some or all of the remaining protocol layer functions are distributed across DUs, and the CU centrally manages the DUs.

[078] The terminal 12 according to the embodiments of the present disclosure is a user-side entity for receiving or transmitting signals, such as a mobile phone. The terminal may also be called a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), and so on. The terminal may be a device with a communication function, such as an automobile, a smart automobile, a mobile phone, a wearable device, a tablet, a computer with a wireless transmitting and receiving function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless communication terminal for an industrial control system, a wireless communication terminal for unmanned automatic driving, a wireless communication terminal for remote medical surgery, a wireless communication terminal for a smart grid, a wireless communication terminal for ensuring transportation safety, a wireless communication terminal in a smart city, a wireless communication terminal in a smart home, and the like. The embodiments of the present invention do not in any way limit the specific technology and the specific type of device used as a terminal.

[079] It should be understood that, according to the embodiments of the present disclosure, the described communication systems are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not impose any limitations on the technical solutions proposed according to the embodiments of the present disclosure. Those of ordinary skill in the art know that as the architecture of communication systems evolves and new service provision scenarios emerge, the technical solutions proposed according to the embodiments of the present disclosure will still be applicable to solving similar technical problems.

[080] Currently, methods for configuring and transmitting an MBS transmission service include an MBMS broadcast service or an MBS transmission service marked with an MBS transmission service identifier, such as a temporary mobile group identity (TMGI) or an MBS transmission service session identifier (ID) or an MBS transmission service session stream identifier (MBS quality stream identifier).

[081] There are two transmission modes for the MBS transmission service. The first mode is a multicast transmission mode. In this first mode, the terminal enters the CONNECTED state of the radio resource control (RRC) protocol to receive the transmitted configuration information about the MBS transmission service, and then the terminal can receive the MBS transmission service. The network device sends a message about receiving the configuration information about the MBS service to the terminal using terminal-specific signaling.

[082] The second mode is a broadcast mode. In this second mode, the terminal can receive the transmitted MBS service configuration information in the idle state (STANDBY) of the radio resource control protocol or in the inactive state (INACTIVE) of the radio resource control protocol or in the connected state (CONNECTED) of the radio resource control protocol, and receive the MBS transmission service service. The network device sends a message about receiving the MBS service configuration information to the terminal using system information such as a system information block (SIB) and MBS transmission service control channel information such as a multicast control channel (MCCH).

[083] The paging method provides that the network device notifies the terminal that a service is arriving using a paging message according to the radio resource control (RRC) protocol, and the paging message contains an identifier of the terminal. The terminal calculates the paging time interval to be monitored in each paging cycle according to the paging cycle configured by the network device and with its own identifier. When the terminal receives a paging message for itself in the idle state (STANDBY) of the radio resource control protocol or in the inactive state (INACTIVE) of the radio resource control protocol, the terminal initiates the connection establishment process.

[084] The paging message is transmitted to the terminal using scheduling on a physical downlink control channel (PDCCH) identified by a paging radio network temporary identity (P-RNTI).

[085] However, when a network device needs to activate a specific MBS transmission service, the network device may notify the terminal of the specific MBS transmission service to be activated by delivering a session identifier of the MBS transmission service (MBS session identifier) in a paging message. At this time, all of the following issues need to be resolved immediately: what resource the network device will use to transmit the paging message delivering the session identifier of the MBS transmission service, how the terminal monitors the paging message, and what specific action the terminal should perform after receiving the paging message.

[086] In view of all this, according to embodiments of the present disclosure, a paging method and device are proposed. A specific paging resource is configured for a paging message delivering information about an MBS transmission service. A terminal monitors the paging message on the specific paging resource if it is interested in the MBS transmission service, and after receiving the paging message, the terminal determines whether to initiate a connection establishment or resumption process according to the MBS transmission service it is interested in. In this way, it is possible to quickly activate the MBS transmission service, thereby saving energy in the terminal.

[087] The paging method and device proposed according to the present disclosure will be described in detail below with reference to the accompanying figures.

[088] As shown in Fig. 2 with a flow chart of the paging method proposed according to embodiments of the present disclosure, this method is performed by a terminal. As shown in Fig. 2, this method may include, among other things, the following steps.

[089] At stage S1, a response is made to the reception of the multicast broadcast service (MBS) paging message configuration information.

[090] According to embodiments of the present disclosure, the configuration information of the MBS multicast broadcast service paging message includes the configuration of the MBS transmission service paging message resource. The configuration of the MBS transmission service paging message resource is specific information for transmitting the MBS transmission service paging message. It can be understood that information such as the location to which the MBS transmission service paging message is delivered can be determined according to the configuration of the MBS transmission service paging message resource.

[091] According to some embodiments, the MBS paging message configuration information includes one or more MBS paging message resource configuration sets. The one or more MBS paging message resource configuration sets may correspond to one or more MBS services.

[092] At step S2, based on the configuration information of the MBS transmission service paging message, it is determined whether to receive the MBS transmission service paging message. The MBS transmission service paging message delivers information about the MBS transmission service.

[093] It can be understood that during the paging process, according to the configuration of the MBS transmission service paging message resource in the configuration information of the MBS transmission service paging message, the terminal determines whether there is an MBS transmission service service that it is interested in. If there is an MBS transmission service service that the terminal is interested in, the terminal receives the MBS transmission service paging message.

[094] According to embodiments of the present disclosure, a terminal responds to receiving configuration information of a multicast broadcast service (MBS) paging message, and determines whether to receive the MBS paging message based on the configuration information of the MBS paging message. The MBS paging message delivers information about the MBS service. According to embodiments of the present disclosure, the terminal is provided with configuration information of the multicast broadcast service (MBS) paging message. The terminal can determine whether to receive the MBS paging message based on the configuration information of the MBS paging message; so that the terminal receives the MBS paging message when the terminal is interested in the MBS service. This makes it possible to quickly activate the MBS service, and provide better energy saving at the terminal.

[095] According to some embodiments, responding to receiving the MBS paging message configuration information comprises responding to receiving the MBS paging message configuration information specified in a protocol; or responding to receiving the MBS paging message configuration information provided by a network device.

[096] According to embodiments of the present disclosure, the MBS paging message configuration information may be specified in a protocol, or may be provided by a network device, or may be implemented in other ways that are not in any way specifically limited in the present disclosure.

[097] According to some embodiments, responding to the MBS paging message configuration information provided by the network device includes a step of responding to the MBS paging message configuration information provided by the network device using system information or MBS control channel information or a radio resource control (RRC) connection release message.

[098] According to embodiments of the present disclosure, if the configuration information of the MBS paging message is provided by the network device, it may be provided using system information, such as a system information block (SIB), or provided using MBS control channel information, such as a multicast control channel (MCCH); or provided using an RRC connection release message, or any other method that can be used to provide the configuration information of the MBS paging message, this is not specifically limited in any way according to embodiments of the present disclosure.

[099] According to some embodiments, the MBS paging message configuration information includes an MBS paging message resource configuration. The MBS paging message resource configuration includes at least one of the following: an MBS paging message control channel; a data channel time slot configuration; a data channel frequency band configuration; an MBS paging message identifier; a paging cycle of the MBS paging message; an MBS paging message start offset; or an association between a downlink beam lobe and an MBS paging message control channel resource or a data channel resource.

[0100] The MBS paging control channel and the data channel time slot configuration include, for example, a call search space in the physical downlink control channel (PDCCH) for scheduling the MBS paging message. If no call search space in the PDCCH is additionally configured for scheduling the MBS paging message, the call search space in the PDCCH of the temporary identifier P-RNTI can be used by default.

[0101] The MBS paging message control channel and the data channel time slot configuration include, for example, a control resource set (CORESET) of the PDCCH for scheduling the MBS paging message. If no PDCCH CORESET is additionally configured for scheduling the MBS paging message, the PDCCH CORESET of the P-RNTI may be used by default.

[0102] The MBS paging message identifier includes, for example, a PDCCH identifier for scheduling the MBS paging message, for example, an MBS identifier identified by a temporary identifier P-RNTI. If no PDCCH is additionally configured for scheduling the MBS paging message, the PDCCH identifier identified by the temporary identifier P-RNTI may be used by default.

[0103] A paging cycle of a paging message of an MBS transmission service, for example, is a paging cycle with a duration of, for example, 50 ms, 100 ms, 200 ms, etc.

[0104] Initial offset of the MBS paging message. For example, the initial offset of the MBS paging message of each MBS paging message cycle may be calculated using the following formula:

[0105] mbs-StartOffset=[(SFN×10)+subframe_number] modulo (mbs-PagingCycle),

[0106] where SFN is a system frame number, subframe number is a subframe number and/or a slot number and/or a symbol number in orthogonal frequency division multiplexing (OFDM), mbs-PagingCycle is a paging cycle of the MBS paging message, and mbs-StartOffset is a starting offset of the position of the MBS paging message.

[0107] For the association between a downlink lobe and a MBS paging message control channel resource or a data channel resource, the data channel resource includes, for example, a physical downlink shared channel (PDSCH) resource.

[0108] According to some embodiments, the configuration information of the MBS paging message further includes an MBS service identifier corresponding to the configuration of the MBS paging message resource. The MBS service identifier includes a temporary mobile group identity (TMGI) or an MBS service session identifier or an MBS service session stream identifier.

[0109] According to some embodiments, the downlink lobe is marked with a synchronous signal block (SSB) identifier or a channel state information reference signal (CSI-RS) identifier.

[0110] According to some embodiments, the association between a downlink lobe and a MBS paging message control channel resource or a data channel resource comprises the following step: in each paging cycle of the MBS paging message, an association is made between the downlink lobe and one or more MBS paging message control channel resources or one or more data channel resources.

[0111] According to embodiments of the present disclosure, in one paging cycle of the MBS paging message, N MBS paging message control channel resources are numbered according to positions in time and frequency intervals, and M downlink lobes are also numbered. The N MBS paging message control channel resources may be alternately assigned to the M downlink lobes in numbering order, or the N MBS paging message control channel resources may be monotonically assigned to the M downlink lobes in numbering order. The numbering is performed according to positions in time and frequency intervals, including numbering according to a position in the time domain or numbering according to a position in the frequency domain.

[0112] According to an exemplary embodiment, if N is 8 and M is 4, in one paging cycle of the MBS paging message, 8 MBS paging message control channel resources are numbered according to the positions of time and frequency intervals, and M downlink lobes are also numbered. The 8 MBS paging message control channel resources are alternately assigned to 4 downlink lobes in the numbering order, or the 8 MBS paging message control channel resources are monotonically assigned to 4 downlink lobes in the numbering order.

[0113] 8 control channel resources of the MBS paging message are assigned alternately to 4 downlink lobes in numbering order. For example, control channel resources with numbers 1 and 5 of the MBS paging message correspond to lobe 1 of the downlink, control channel resources with numbers 2 and 6 of the MBS paging message correspond to lobe 2 of the downlink, control channel resources with numbers 3 and 7 of the MBS paging message correspond to lobe 3 of the downlink, and control channel resources with numbers 4 and 6 of the MBS paging message correspond to lobe 4 of the downlink.

[0114] 8 control channel resources of the MBS paging message are monotonically assigned to 4 downlink lobes in numbering order. For example, control channel resources with numbers 1 and 2 of the MBS paging message correspond to lobe 1 of the downlink, control channel resources with numbers 3 and 4 of the MBS paging message correspond to lobe 2 of the downlink, control channel resources with numbers 5 and 6 of the MBS paging message correspond to lobe 3 of the downlink, and control channel resources with numbers 7 and 8 of the MBS paging message correspond to lobe 4 of the downlink.

[0115] According to embodiments of the present disclosure, in one paging cycle of the MBS paging message, N data channel resources of the MBS paging message are numbered according to positions in time intervals and frequency, and M downlink lobes are also numbered. The N data channel resources may be alternately assigned to the M downlink lobes in numbering order, or the N data channel resources may be monotonically assigned to the M downlink lobes in numbering order. The numbering is performed according to positions in time intervals and frequency, including numbering according to a position in the time domain or numbering according to a position in the frequency domain.

[0116] According to an exemplary embodiment, if N is 8 and M is 4, in one paging cycle of the MBS paging message, 8 data channel resources are numbered according to the positions of time and frequency intervals, and M downlink lobes are also numbered. The 8 data channel resources may be alternately assigned to 4 downlink lobes in the numbering order, or the 8 data channel resources may be monotonically assigned to 4 downlink lobes in the numbering order.

[0117] The 8 data channel resources may be assigned alternately to the 4 downlink lobes in number order. For example, the data channel resources with numbers 1 and 5 correspond to downlink lobe 1, the data channel resources with numbers 2 and 6 correspond to downlink lobe 2, the data channel resources with numbers 3 and 7 correspond to downlink lobe 3, and the data channel resources with numbers 4 and 8 correspond to downlink lobe 4.

[0118] The 8 data channel resources may be monotonically assigned to 4 downlink lobes in numbering order. For example, the data channel resources with numbers 1 and 2 correspond to downlink lobe 2, the data channel resources with numbers 3 and 4 correspond to downlink lobe 2, the data channel resources with numbers 5 and 6 correspond to downlink lobe 3, and the data channel resources with numbers 7 and 8 correspond to downlink lobe 4.

[0119] According to some embodiments, if one set of MBS paging resource configurations corresponds to a plurality of MBS services, then the plurality of MBS paging resource configurations in the one set of MBS paging resource configurations may be assigned to different MBS services respectively. For example, if there are 2 PDCCH resources in one MBS paging cycle, then PDCCH resource-1 is assigned to MBS service-1, and PDCCH resource-2 is assigned to MBS service-2.

[0120] According to some embodiments, the MBS service information includes an MBS service identifier or an MBS service tag.

[0121] The MBS service identifier includes a temporary mobile group identity (TMGI) or an MBS service session identifier or an MBS service stream session identifier.

[0122] The MBS transmission service label includes a system message or a MBS transmission service list provided in a user service description (USD) file. Each item of the MBS transmission service list corresponds to an MBS transmission service, and the label of an item in the MBS transmission service list corresponds to the label of the MBS transmission service. For example, if there are 4 MBS transmission service services (MBS transmission service-1, MBS transmission service-2, MBS transmission service-3, and MBS transmission service-4) in the MBS transmission service list, and the items in the MBS transmission service list are labeled in order as item-1, item-2, item-3, and item-4, then the labels of item-1, item-2, item-3, and item-4 correspond to MBS transmission service-1, MBS transmission service-2, MBS transmission service-3, and MBS transmission service-4.

[0123] As shown in Fig. 3, the method proposed according to the embodiments of the present disclosure further provides the following: after the step S1 of responding to the reception of the configuration information of the MBS paging message, the step S3 is performed, that is, it is determined whether to monitor the transmission of the MBS paging message based on the configuration information of the MBS paging message.

[0124] For example, after receiving the configuration information of the MBS paging message, the terminal monitors the scheduling information corresponding to the MBS paging message on the PDCCH channel resource corresponding to the configuration of the MBS paging message resource during a paging cycle of 100 ms.

[0125] According to some embodiments, determining whether to monitor the transmission of the MBS paging message based on the configuration information of the MBS paging message includes a step of refusing to monitor or stopping monitoring the MBS paging message in a case where the RRC connection state is the CONNECTED state of the radio resource control protocol, or the current resident cell does not provide the MBS paging service, or the current resident cell does not provide the MBS paging service in which the terminal is interested; or monitoring or starting monitoring the transmission of the MBS paging message in a case where the RRC connection state is the STANDBY state of the radio resource control protocol or the INACTIVE state of the radio resource control protocol, or the current resident cell provides the MBS paging service, or the current resident cell provides the MBS paging service in which the terminal is interested.

[0126] The current residential cell not providing the MBS transmission service includes the case where the system information corresponding to the MBS transmission service is not provided in the current residential cell of the terminal. The current residential cell not providing the MBS transmission service in which the terminal is interested, for example, includes the case where the system information of the current residential cell indicates that the cell provides the MBS transmission service-1, but the terminal is interested in the MBS transmission service-2.

[0127] According to some embodiments, the MBS transmission service in which the terminal is interested includes an MBS transmission service labeled with an MBS transmission service identifier in which the terminal is interested and which is provided in a user service description (USD) file; or an MBS transmission service with an established MBS transmission service session; or an MBS transmission service to which the terminal has joined in a data transmission group.

[0128] An example of an MBS transmission service service marked with an identifier of the MBS transmission service in which the terminal is interested and which is provided in the user service description (USD) file is the case where the USD file indicates that the temporary identifier TMGI-1 or the identifier ID-1 of the MBS transmission service session refers to the MBS transmission service in which the terminal is interested.

[0129] An example of an MBS transmission service service with an established MBS transmission service session is a case where the MBS transmission service service-1 has established a corresponding MBS transmission service session. It can be understood that for the MBS transmission service service-1 with an established MBS transmission service session, the same type of MBS transmission service-1 has already been used by the terminal, which means that the terminal must be interested in the MBS transmission service-1.

[0130] An example of an MBS transmission service for which the terminal has joined a transmission group is a case where the terminal has joined a transmission group of MBS transmission service-1 by a non-access stratum (NAS) agreement message. It can be understood that the users in the transmission group will be notified of what programs will be executed by broadcasting. Let the terminal join the transmission group of MBS transmission service-1 by a non-access stratum (NAS) agreement message, this indirectly indicates that the terminal is interested in MBS transmission service-1 in the transmission group.

[0131] According to some embodiments, determining whether to monitor the transmission of the MBS paging message based on the configuration information of the MBS paging message further comprises a step of selecting a location of a resource in one paging cycle of the MBS paging message for monitoring the transmission of the MBS paging message, in a case where the configuration of the MBS paging message resource includes an association between a downlink lobe and a control channel resource of the MBS paging message or a data channel resource.

[0132] According to some embodiments, selecting a resource location in one paging cycle of the MBS paging message includes a step in which, in one paging cycle of the MBS paging message, selecting to monitor the transmission of the MBS paging message is performed in the case where the measurement result of the lobe signal is greater than a threshold value or the lobe is a lobe indicated for receiving the paging message.

[0133] For a specified beam lobe for receiving a paging message, for example, there are 4 control channel resources of the MBS paging message or 4 data channel resources in one paging cycle, which correspond to 4 beam lobes. When the network device specifies the terminal to receive the paging message on lobe-1, the terminal selects to receive the paging message on lobe-1 as specified by the network device.

[0134] As shown in Fig. 4, the paging method proposed according to the embodiments of the present disclosure further provides the following: performing step S41, i.e. starting reception of the MBS transmission service in the case where a decision is made in step S2 to receive the MBS transmission service paging message based on the configuration information of the MBS transmission service paging message.

[0135] According to some embodiments, starting the reception of the MBS transmission service includes a step of initiating a process of accessing a connection, or receiving the corresponding MBS transmission service according to a configuration of a paging message resource of the MBS transmission service.

[0136] According to some embodiments, initiating a connection access process includes a step in which the terminal provides indicator information to indicate that it is necessary to receive an MBS transmission service.

[0137] According to embodiments of the present disclosure, a terminal receives a paging message of an MBS transmission service, starts receiving the MBS transmission service, and initiates a process of accessing a connection. The information about the MBS transmission service delivered in the paging message of the MBS transmission service includes the MBS transmission service that the terminal is interested in, and the terminal provides indicator information for indicating that it is necessary to receive the MBS transmission service.

[0138] The indicator information may include at least one of the following:

[0139] 1) the reason that access to the connection is necessary for receiving the MBS transmission service service, for example, the reason is that the RRCSetupRequest or RRCResumeRequest message is a mobile terminated-MBS (MT-MBS) message sent to the mobile phone, that is, the connection establishment process is initiated by receiving the MBS transmission service call.

[0140] 2) the MBS transmission service service information, for example, the MBS transmission service service information, includes an MBS transmission service service identifier or an MBS transmission service service label.

[0141] The MBS service identifier includes a temporary mobile group identity (TMGI) or an MBS service session identifier or an MBS service session stream identifier.

[0142] The MBS transmission service label includes a system message or a MBS transmission service list provided in a user service description (USD) file. Each item of the MBS transmission service list corresponds to an MBS transmission service, and the label of an item in the MBS transmission service list corresponds to the label of the MBS transmission service. For example, if there are 4 MBS transmission service services (MBS transmission service-1, MBS transmission service-2, MBS transmission service-3, and MBS transmission service-4) in the MBS transmission service list, and the items in the MBS transmission service list are labeled in order as item-1, item-2, item-3, and item-4, then the labels of item-1, item-2, item-3, and item-4 correspond to MBS transmission service-1, MBS transmission service-2, MBS transmission service-3, and MBS transmission service-4.

[0143] According to some embodiments, initiating a connection access process includes a step of initiating a connection establishment process or a connection resumption process.

[0144] According to embodiments of the present disclosure, initiating the connection establishment process includes the following: if the terminal is in the idle state and the MBS transmission service is sent in the first mode, the terminal enters the connected (CONNECTED) state of the radio resource control (RRC) protocol to receive the transmitted configuration information about the MBS transmission service, and then the terminal can receive the MBS transmission service. The network device sends a message about receiving the configuration information about the MBS service to the terminal using terminal-specific signaling, and the terminal initiates the connection establishment process at this point in time. More specifically, initiating the connection establishment process includes, for example, transmitting a SetupRequest message of the RRC protocol.

[0145] According to embodiments of the present disclosure, initiating a connection resumption process includes the following: if the terminal is in an inactive state (INACTIVE), and the MBS transmission service is transmitted in a first mode, the terminal enters a connected (CONNECTED) state of the radio resource control (RRC) protocol to receive transmitted configuration information about the MBS transmission service, and then the terminal can receive the MBS transmission service. The network device sends a message about receiving the configuration information about the MBS service to the terminal using terminal-specific signaling, and the terminal initiates a connection resumption process. More specifically, initiating the connection resumption process includes, for example, transmitting a ResumeRequest message of the RRC protocol.

[0146] Receiving the corresponding MBS transmission service service according to the MBS transmission service paging message resource configuration includes the following: the MBS transmission service service is sent in the second broadcast mode, the terminal can receive the transmitted MBS service configuration information in the idle state (STANDBY) of the radio resource control protocol or in the inactive state (INACTIVE) of the radio resource control protocol or in the connected state (CONNECTED) of the radio resource control protocol, and receive the MBS transmission service service. The network device sends a message about receiving the MBS service configuration information to the terminal using system information such as a system information block (SIB) and MBS transmission service control channel information such as a multicast control channel (MCCH), and the terminal receives the MBS transmission service paging message resource configuration and receives the corresponding MBS transmission service service using the MBS transmission service paging message resource configuration.

[0147] According to some embodiments, the configuration information of the MBS transmission service paging message includes an MBS transmission service access control parameter. Starting the reception of the MBS transmission service includes a step of responding to the reception of the MBS transmission service access control parameter and determining whether to initiate the connection access process.

[0148] According to some embodiments, the MBS transmission service access control parameter includes at least one of the following: a specific access identifier or access type corresponding to the MBS transmission service; an access randomization parameter for the MBS transmission service; or a configuration of the duration of access prohibition after determining that an access attempt is prohibited.

[0149] A specific access identifier or an access type corresponding to the MBS transmission service includes an access ID such as an access identifier-1, or an access type such as an access category-1. If the specific access identifier or the access type indicates access prohibition (for example, prohibited) in the current residential cell, the terminal will not initiate an access request.

[0150] According to some embodiments, the MBS service access randomization parameter includes a random number from an access permission interval.

[0151] Regarding the random number from the range for access permission, let, for example, the range of the random parameter be [0, 1], and the range of the random parameter for access permission be [0, 0.5]. The terminal selects a random parameter from the range [0, 1] using a uniform distribution method, and if the random parameter falls within the range [0, 0.5], the terminal can initiate an access attempt.

[0152] According to some embodiments, the access prohibition duration configuration includes a duration for the access prohibition timer or a scaling parameter of the randomization value for the access prohibition timer.

[0153] According to embodiments of the present disclosure, with respect to the duration for the access prohibition timer, it can be understood that a corresponding duration is configured using the access prohibition timer such that when it is determined that an access attempt is prohibited, another access during the corresponding duration is also prohibited.

[0154] According to embodiments of the present disclosure, with regard to the parameter of the scaling of the randomization value for the access prohibition timer, for example, after determining that access to the MBS transmission service is prohibited, it is necessary to start the access prohibition timer for the MBS transmission service, and the terminal does not initiate an access request during the operation of this timer. If the duration of the access prohibition timer configured by the network device is a, the terminal selects a random number X from the range of [0, 1] using the uniform distribution method, and the scaling parameter of the random number X configured on the network side or specified in the protocol is b (where the value of b can be equal to "1", that is, no additional scaling is performed on the random number X), and then the final value of the random number is bX, the terminal calculates the configured duration y of the access prohibition using the values a and bX in the calculations.

[0155] As shown in Fig. 4, the paging method proposed according to the embodiments of the present disclosure further comprises the following: performing step S42, i.e., refusing to start receiving the MBS transmission service service in the case where a decision is made in step S2 not to receive the MBS transmission service paging message based on the configuration information of the MBS transmission service paging message. Refusing to start receiving the MBS transmission service message involves refusing to initiate the connection access process.

[0156] According to some embodiments, failure to initiate a connection access process includes failure to transmit an RRC message corresponding to an access request or failure to transmit random access request information.

[0157] If the RRC Radio Resource Control Protocol message corresponding to the access request is not transmitted, the RRC Radio Resource Control Protocol message contains a Connection Establishment Request message or a Connection Resumption Request message.

[0158] Refusing to transmit random access request information, for example, includes refusing to transmit the Msgl response information of the first random access of the 4-stage random access process, or refusing to transmit the MsgB response information of the second random access of the 2-stage random access process.

[0159] According to some embodiments, determining whether to receive the MBS transmission service paging message based on the MBS transmission service paging message configuration information includes the step of: refusing to receive the MBS transmission service paging message in a case where the Radio Resource Control (RRC) connection state is the CONNECTED state of the Radio Resource Control protocol, or the current residential cell does not provide the MBS transmission service, or the current residential cell does not provide the MBS transmission service in which the terminal is interested; or receiving a paging message of the MBS transmission service in the case where the Radio Resource Control (RRC) connection state is the RRC idle state or the RRC inactive state, or the current resident cell provides the MBS transmission service, or the current resident cell provides the MBS transmission service in which the terminal is interested.

[0160] Fig. 5 shows a flow chart of another paging method proposed according to embodiments of the present disclosure. This method is performed by a network device. As shown in Fig. 5, this method may include, among other things, the following steps.

[0161] At step S10, a response is made to the transmission of the configuration information of the paging message of the multicast broadcast service (MBS).

[0162] According to embodiments of the present disclosure, the configuration information of the MBS multicast broadcast service paging message includes the configuration of the MBS transmission service paging message resource. The configuration of the MBS transmission service paging message resource is specific information for transmitting the MBS transmission service paging message. It can be understood that information such as the location to which the MBS transmission service paging message is delivered can be determined according to the configuration of the MBS transmission service paging message resource.

[0163] According to some embodiments, the MBS paging message configuration information includes one or more MBS paging message resource configuration sets. The one or more MBS paging message resource configuration sets may correspond to one or more MBS services.

[0164] In step S20, based on the configuration information of the paging message of the transmission service, a paging message of the MBS transmission service is transmitted. The paging message of the MBS transmission service delivers information about the MBS transmission service.

[0165] It can be understood that during the paging process, according to the configuration of the MBS transmission service paging message resource in the configuration information of the MBS transmission service paging message, the terminal determines whether there is an MBS transmission service service that it is interested in. If there is an MBS transmission service service that the terminal is interested in, the terminal receives the MBS transmission service paging message.

[0166] According to embodiments of the present disclosure, after a network device transmits configuration information of a multicast broadcast service (MBS) paging message, a MBS paging message is transmitted based on the configuration information of the MBS paging message. The MBS paging message delivers information about the MBS paging service. According to embodiments of the present disclosure, after a network device transmits configuration information of a multicast broadcast service (MBS) paging message, the configuration information of the MBS paging message is provided to a terminal, the terminal can determine whether to receive the MBS paging message based on the configuration information of the MBS paging message; and the terminal receives the MBS paging message when the terminal is interested in the MBS paging service. This allows you to quickly activate the MBS transmission service and provide better energy savings on the terminal.

[0167] According to some embodiments, responding to transmission of MBS paging message configuration information comprises responding to transmission of MBS paging message configuration information specified in a protocol; or responding to transmission of configured MBS paging message configuration information.

[0168] According to embodiments of the present disclosure, the MBS paging message configuration information may be specified in a protocol, or may be provided by a network device, or may be implemented in other ways that are not in any way specifically limited in the present disclosure.

[0169] According to some embodiments, responding to transmission of configured configuration information of the MBS transmission service paging message includes a step of responding to transmission of configuration information of the MBS transmission service paging message configured using system information or MBS transmission service control channel information or an RRC connection release message.

[0170] According to embodiments of the present disclosure, if the configuration information of the MBS paging message is provided by the network device, it may be provided using system information, such as a system information block (SIB), or provided using MBS control channel information, such as a multicast control channel (MCCH); or provided using an RRC connection release message, or any other method that can be used to provide the configuration information of the MBS paging message, this is not specifically limited in any way according to embodiments of the present disclosure.

[0171] According to some embodiments, the MBS paging message configuration information includes an MBS paging message resource configuration. The MBS paging message resource configuration includes at least one of the following: an MBS paging message control channel; a data channel time slot configuration; a data channel frequency band configuration; an MBS paging message identifier; a paging cycle of the MBS paging message; an MBS paging message start offset; or an association between a downlink beam lobe and an MBS paging message control channel resource or a data channel resource.

[0172] The MBS paging control channel and the data channel time slot configuration include, for example, a call search space in the physical downlink control channel (PDCCH) for scheduling the MBS paging message. If no call search space in the PDCCH is additionally configured for scheduling the MBS paging message, the call search space in the PDCCH of the temporary identifier P-RNTI can be used by default.

[0173] The MBS paging message control channel and the data channel time slot configuration include, for example, a control resource set (CORESET) of the PDCCH for scheduling the MBS paging message. If no PDCCH CORESET is additionally configured for scheduling the MBS paging message, the PDCCH CORESET of the P-RNTI may be used by default.

[0174] The MBS paging message identifier includes, for example, a PDCCH identifier for scheduling the MBS paging message, for example, an MBS identifier identified by a temporary identifier P-RNTI. If no PDCCH is additionally configured for scheduling the MBS paging message, the PDCCH identifier identified by the temporary identifier P-RNTI may be used by default.

[0175] A paging cycle of a paging message of an MBS transmission service, for example, is a paging cycle with a duration of, for example, 50 ms, 100 ms, 200 ms, etc.

[0176] Initial offset of the MBS paging message. For example, the initial offset of the MBS paging message of each MBS paging message cycle may be calculated using the following formula:

[0177] mbs-StartOffset=[(SFN×10)+subframe_number] modulo (mbs-PagingCycle),

[0178] where SFN is a system frame number, subframe number is a subframe number and/or a slot number and/or a symbol number in orthogonal frequency division multiplexing (OFDM), mbs-PagingCycle is a paging cycle of the MBS paging message, and mbs-StartOffset is a starting offset of the position of the MBS paging message.

[0179] For the association between a downlink lobe and a MBS paging message control channel resource or a data channel resource, the data channel resource includes, for example, a physical downlink shared channel (PDSCH) resource.

[0180] According to some embodiments, the configuration information of the MBS paging message further includes an MBS service identifier corresponding to the configuration of the MBS paging message resource. The MBS service identifier includes a temporary mobile group identity (TMGI) or an MBS service session identifier or an MBS service session stream identifier.

[0181] According to some embodiments, the downlink lobe is labeled with a synchronization signal block identifier or a channel state information reference signal identifier.

[0182] According to some embodiments, the association between a downlink lobe and a MBS paging message control channel resource or a data channel resource comprises the following step: in each paging cycle of the MBS paging message, an association is made between the downlink lobe and one or more MBS paging message control channel resources or one or more data channel resources.

[0183] According to embodiments of the present disclosure, in one paging cycle of the MBS paging message, N MBS paging message control channel resources are numbered according to positions in time and frequency intervals, and M downlink lobes are also numbered. The N MBS paging message control channel resources may be alternately assigned to the M downlink lobes in numbering order, or the N MBS paging message control channel resources may be monotonically assigned to the M downlink lobes in numbering order. The numbering is performed according to positions in time and frequency intervals, including numbering according to a position in the time domain or numbering according to a position in the frequency domain.

[0184] According to an exemplary embodiment, if N is 8 and M is 4, in one paging cycle of the MBS paging message, 8 MBS paging message control channel resources are numbered according to the positions of time and frequency intervals, and M downlink lobes are also numbered. The 8 MBS paging message control channel resources are alternately assigned to 4 downlink lobes in the numbering order, or the 8 MBS paging message control channel resources are monotonically assigned to 4 downlink lobes in the numbering order.

[0185] 8 control channel resources of the MBS paging message are assigned alternately to 4 downlink lobes in numbering order. For example, control channel resources with numbers 1 and 5 of the MBS paging message correspond to lobe 1 of the downlink, control channel resources with numbers 2 and 6 of the MBS paging message correspond to lobe 2 of the downlink, control channel resources with numbers 3 and 7 of the MBS paging message correspond to lobe 3 of the downlink, and control channel resources with numbers 4 and 6 of the MBS paging message correspond to lobe 4 of the downlink.

[0186] 8 control channel resources of the MBS paging message are monotonically assigned to 4 downlink lobes in numbering order. For example, control channel resources with numbers 1 and 2 of the MBS paging message correspond to lobe 1 of the downlink, control channel resources with numbers 3 and 4 of the MBS paging message correspond to lobe 2 of the downlink, control channel resources with numbers 5 and 6 of the MBS paging message correspond to lobe 3 of the downlink, and control channel resources with numbers 7 and 8 of the MBS paging message correspond to lobe 4 of the downlink.

[0187] According to embodiments of the present disclosure, in one paging cycle of the MBS paging message, N data channel resources of the MBS paging message are numbered according to positions in time and frequency intervals, and M downlink lobes are also numbered. The N data channel resources may be alternately assigned to the M downlink lobes in numbering order, or the N data channel resources may be monotonically assigned to the M downlink lobes in numbering order. The numbering is performed according to positions in time and frequency intervals, including numbering according to a position in the time domain or numbering according to a position in the frequency domain.

[0188] According to an exemplary embodiment, if N is 8 and M is 4, in one paging cycle of the MBS paging message, 8 data channel resources are numbered according to the positions of time and frequency intervals, and M downlink lobes are also numbered. The 8 data channel resources may be alternately assigned to 4 downlink lobes in the numbering order, or the 8 data channel resources may be monotonically assigned to 4 downlink lobes in the numbering order.

[0189] The 8 data channel resources may be assigned alternately to 4 downlink lobes in numbering order. For example, data channel resources with numbers 1 and 5 correspond to downlink lobe 1, data channel resources with numbers 2 and 6 correspond to downlink lobe 2, data channel resources with numbers 3 and 7 correspond to downlink lobe 3, and data channel resources with numbers 4 and 8 correspond to downlink lobe 4.

[0190] The 8 data channel resources may be monotonically assigned to 4 downlink lobes in numbering order. For example, the data channel resources with numbers 1 and 2 correspond to downlink lobe 2, the data channel resources with numbers 3 and 4 correspond to downlink lobe 2, the data channel resources with numbers 5 and 6 correspond to downlink lobe 3, and the data channel resources with numbers 7 and 8 correspond to downlink lobe 4.

[0191] According to some embodiments, if one set of MBS paging resource configurations corresponds to a plurality of MBS services, then the plurality of MBS paging resource configurations in the one set of MBS paging resource configurations may be assigned to different MBS services respectively. For example, if there are 2 PDCCH resources in one MBS paging cycle, then PDCCH resource-1 is assigned to MBS service-1, and PDCCH resource-2 is assigned to MBS service-2.

[0192] According to some embodiments, the MBS service information includes an MBS service identifier or an MBS service tag.

[0193] The MBS service identifier includes a temporary mobile group identity (TMGI) or an MBS service session identifier or an MBS service session stream identifier.

[0194] The MBS transmission service label includes a system message or a MBS transmission service list provided in a user service description (USD) file. Each item of the MBS transmission service list corresponds to an MBS transmission service, and the label of an item in the MBS transmission service list corresponds to the label of the MBS transmission service. For example, if there are 4 MBS transmission service services (MBS transmission service-1, MBS transmission service-2, MBS transmission service-3, and MBS transmission service-4) in the MBS transmission service list, and the items in the MBS transmission service list are labeled in order as item-1, item-2, item-3, and item-4, then the labels of item-1, item-2, item-3, and item-4 correspond to MBS transmission service-1, MBS transmission service-2, MBS transmission service-3, and MBS transmission service-4.

[0195] As shown in Fig. 6, according to the embodiments of the present disclosure, the configuration information of the MBS transmission service paging message includes an MBS transmission service access control parameter. After step S20 is performed, that is, the MBS transmission service paging message is transmitted based on the configuration information of the MBS transmission service paging message, step S30 is performed, in which the terminal is controlled to initiate or not the connection access process according to the MBS transmission service access control parameter.

[0196] According to some embodiments, controlling a terminal to initiate a connection access process includes a stage of controlling the terminal to provide indicator information indicating that it is necessary to receive an MBS transmission service.

[0197] According to some embodiments, the terminal is controlled to initiate a connection access process, and the terminal is controlled to provide indicator information to indicate that it is necessary to receive the MBS transmission service.

[0198] The indicator information may include at least one of the following:

[0199] 1) the reason that access to the connection is necessary for receiving the MBS transmission service service, for example, the reason is that the RRCSetupRequest or RRCResumeRequest message is a mobile terminated-MBS (MT-MBS) message sent to the mobile phone, that is, the connection establishment process is initiated by receiving the MBS transmission service call.

[0200] 2) the MBS transmission service service information, for example, the MBS transmission service service information, includes an MBS transmission service service identifier or an MBS transmission service service label.

[0201] The MBS service identifier includes a temporary mobile group identity (TMGI) or an MBS service session identifier or an MBS service session stream identifier.

[0202] The MBS transmission service label includes a system message or a MBS transmission service list provided in a user service description (USD) file. Each item of the MBS transmission service list corresponds to an MBS transmission service, and the label of an item in the MBS transmission service list corresponds to the label of the MBS transmission service. For example, if there are 4 MBS transmission service services (MBS transmission service-1, MBS transmission service-2, MBS transmission service-3, and MBS transmission service-4) in the MBS transmission service list, and the items in the MBS transmission service list are labeled in order as item-1, item-2, item-3, and item-4, then the labels of item-1, item-2, item-3, and item-4 correspond to MBS transmission service-1, MBS transmission service-2, MBS transmission service-3, and MBS transmission service-4.

[0203] According to some embodiments, the MBS transmission service access control parameter includes at least one of the following: a specific access identifier or access type corresponding to the MBS transmission service; an access randomization parameter for the MBS transmission service; or a configuration of the duration of access prohibition after determining that an access attempt is prohibited.

[0204] A specific access identifier or an access type corresponding to the MBS transmission service includes an access ID such as an access identifier-1, or an access type such as an access category-1. If the specific access identifier or access type indicates access prohibition (for example, prohibited) in the current residential cell, the terminal will not initiate an access request.

[0205] According to some embodiments, the MBS service access randomization parameter includes a random number from an access permission interval.

[0206] Regarding the random number from the range for access permission, let, for example, the range of the random parameter be [0, 1], and the range of the random parameter for access permission be [0, 0.5]. The terminal selects a random parameter from the range [0, 1] using a uniform distribution method, and if the random parameter falls within the range [0, 0.5], the terminal can initiate an access attempt.

[0207] According to some embodiments, the access prohibition duration configuration includes a duration for the access prohibition timer or a scaling parameter of the randomization value for the access prohibition timer.

[0208] According to embodiments of the present disclosure, with respect to the duration for the access prohibition timer, it can be understood that a corresponding duration is configured using the access prohibition timer such that when it is determined that an access attempt is prohibited, another access is also prohibited during the corresponding duration.

[0209] According to embodiments of the present disclosure, with regard to the parameter of the scaling of the randomization value for the access prohibition timer, for example, after determining that access to the MBS transmission service is prohibited, it is necessary to start the access prohibition timer for the MBS transmission service, and the terminal does not initiate an access request during the operation of this timer. If the duration of the access prohibition timer configured by the network device is a, the terminal selects a random number X from the range of [0, 1] using the uniform distribution method, and the scaling parameter of the random number X configured on the network side or specified in the protocol is b (where the value of b can be equal to "1", that is, no additional scaling is performed on the random number X), and then the final value of the random number is bX, the terminal calculates the configured duration y of the access prohibition using the values a and bX in the calculations.

[0210] According to some embodiments, in the case where the terminal is controlled to refuse to initiate the connection access process according to the MBS transmission service access control parameter, the RRC message corresponding to the access request is not transmitted, or random access request information is not transmitted.

[0211] If the RRC Radio Resource Control Protocol message corresponding to the access request is not transmitted, the RRC Radio Resource Control Protocol message contains a Connection Establishment Request message or a Connection Resumption Request message.

[0212] Refusing to transmit random access request information, for example, includes refusing to transmit the Msgl response information of the first random access of the 4-stage random access process, or refusing to transmit the MsgB response information of the second random access of the 2-stage random access process.

[0213] According to the paging method proposed according to the above-described embodiments of the present disclosure, the specific process of the corresponding stage is similar to the paging method proposed according to some of the above-described embodiments, and the same useful results are achieved, and therefore it will not be described again here.
