Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, and more particularly, to a paging method and device, a communication device, and a storage medium. BACKGROUND

[0002] Under a discontinuous reception (DRX) mechanism, a user equipment (UE) such as a mobile terminal stops monitoring a paging message at a paging occasion (PO) according to a DRX rule, thereby achieving the purpose of power saving.

[0003] In a radio resource control (RRC) idle state, a UE monitors a paging channel of a paging initiated by a core network (CN); in an RRC inactive state, the UE also monitors the paging channel of the paging initiated by a radio access network (RAN). The UE does not need to continuously monitor the paging channel, wherein the UE in the RRC idle state or the UE in the RRC inactive state only needs to monitor the paging channel during one paging occasion (PO) in each DRX cycle. The UE monitors the PO by calculating based on a UE identifier according to a formula. SUMMARY

[0004] Therefore, the present application provides a paging method and device, a communication device, and a storage medium.

[0005] In a first aspect, a paging method is provided, wherein the method is performed by a network device, and the method comprises:

[0007] In a second aspect, a paging method is provided, wherein the method is performed by a user equipment (UE), and the method comprises:

[0008] receiving a first type of paging message of a UE group to which the UE belongs, wherein the UE group comprises at least one UE.

[0010] a first sending module configured to send a first type of paging message for a UE group, wherein the UE group comprises at least one UE.

[0011] In a fourth aspect, the present disclosure provides a paging device, wherein the device comprises:

[0012] The second receiving module is configured to receive a first type of paging message of a UE group to which the UE belongs, wherein the UE group comprises at least one UE.

[0013] In a fifth aspect, the present disclosure provides a communication device, comprising a processor, a memory, and an executable program stored in the memory and capable of being executed by the processor, wherein the processor executes the executable program to perform the steps of the paging method according to the first aspect or the second aspect.

[0015] According to the paging method, the device, the communication device, and the storage medium provided by the embodiments of the present disclosure, the network device sends a first type of paging message for a UE group, wherein the UE group comprises at least one UE. In this way, the base station sends a first type of paging message for a UE group, and the UEs in the same UE group can respond based on the same first type of paging message. On the one hand, the efficiency of the base station paging UEs is improved, and on the other hand, multiple UEs can respond to the paging message at the same time, meeting the requirements of data coordination and other communication services that require simultaneous wake-up.

For example, a first information could be termed a second information without departing from the scope of the disclosure. As used herein, the term "if' can be interpreted to mean "when" or "upon" or "in response to determining" depending on the context.

[0038] Reference is made to Figure 1 which shows a structure diagram of a wireless communication system provided by the embodiments of the disclosure. As shown in Figure 1 , the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system can include a plurality of terminals 11 and a plurality of base stations 12.

[0039] The terminal 11 can be a device that provides voice and / or data connectivity to a user. The terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN), and the terminal 11 can be an Internet of Things terminal, such as a sensor device, a mobile phone (or called "cellular" phone), and a computer with an Internet of Things terminal, for example, which can be fixed, portable, pocket, hand-held, computer-embedded, or vehicle-mounted. For example, a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or a user equipment (UE). Alternatively, the terminal 11 can also be a device of an unmanned aerial vehicle. Alternatively, the terminal 11 can also be a vehicle-mounted device, which can be a vehicle-mounted computer with wireless communication function or a wireless communication device externally connected to the vehicle-mounted computer. Alternatively, the terminal 11 can also be a roadside device, which can be a street lamp, a signal lamp, or other roadside devices with wireless communication function, etc.

[0040] The base station 12 can be a network-side device in a wireless communication system. The wireless communication system can be a 4th generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system, or the wireless communication system can also be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system can also be a next generation of 5G system. In the 5G system, the access network can be referred to as a New Generation-Radio Access Network (NG-RAN). Alternatively, the MTC system.

[0041] The base station 12 can be an evolved NodeB (eNB) in a 4G system. Alternatively, the base station 12 can be a base station (gNB) in a 5G system using a centralized and distributed architecture. When the base station 12 uses a centralized and distributed architecture, it generally includes a central unit (CU) and at least two distributed units (DUs). The central unit is provided with a protocol stack of a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a media access control (MAC) layer; and the distributed unit is provided with a protocol stack of a physical (PHY) layer. The specific implementation of the base station 12 is not limited in the embodiments of the present disclosure.

[0042] The base station 12 and the terminal 11 can establish a wireless connection through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on a fourth generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, such as a new radio interface; or the wireless air interface can also be a wireless air interface based on a more next generation mobile communication network technology standard of 5G.

[0043] In some embodiments, the terminals 11 can also establish an E2E (End to End) connection. For example, V2V (vehicle to vehicle) communication, V2I (vehicle to infrastructure) communication, and V2P (vehicle to pedestrian) communication in vehicle to everything (V2X) communication, and the like.

[0044] In some embodiments, the wireless communication system can also include a network management device 13.

[0045] A plurality of base stations 12 are connected to a network management device 13. The network management device 13 can be a core network device in a wireless communication system, for example, the network management device 13 can be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the network management device can also be other core network devices, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS), etc. The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0046] The execution subject involved in the embodiments of the present disclosure includes but is not limited to: a UE such as a mobile phone terminal supporting cellular mobile communication, and a network device such as a base station and / or a core network.

[0047] One application scenario of the embodiments of the present disclosure is that multiple information sources or forms are involved in the multi-modality, for example, a person has tactile, auditory, visual, and olfactory senses; and information media includes voice, video, and text, etc. In order to perceive the input of the user from multiple dimensions, the types and quantities of APPs and / or devices for multi-modality information collection are numerous, including multiple cameras, sound boxes, sensors, keyboards, fingerprint collectors, etc. Among them, these devices for collecting multiple modalities of information can be used in the same device or across devices.

[0048] Data fusion (also known as information fusion) of the multi-modality data set needs to be performed on the server side, that is, incomplete information about an environmental feature provided by a plurality of sensors or information sources is integrated and analyzed to form a relatively complete and consistent perception description, so as to achieve more accurate recognition and judgment functions.

[0049] After the server completes data fusion and makes a decision, a multi-modality output is obtained, and this process is a service distribution process. Often, the service is not distributed to a single device, but is likely to be associated with a linkage of a plurality of devices. For example, through voiceprint and video judgment, the master can be determined to return home, and at the same time, the window curtain can be pulled up and the air conditioner can be turned on. Here, the problem of group cooperation between a plurality of output devices needs to be solved.

[0050] The multiple triggering devices can be different UEs, and the POs cannot wake up the cooperative devices at the same time because the UEs have different UE identities. Therefore, how to realize paging group cooperation, that is, multiple different types of UEs are woken up at the same time in a multi-modal scenario, is a problem to be solved.

[0051] As shown in Figure 2a The present exemplary embodiment provides a paging method, which can be executed by a network device of a cellular mobile communication system, and the like, and includes the following steps.

[0052] Step 201: sending a first type of paging message for a UE group, wherein the UE group includes at least one UE.

[0053] The UE can be a mobile terminal and the like that uses a cellular mobile communication technology to perform wireless communication. The network device can be an access network device such as a base station of a cellular mobile communication system and / or a core network and the like, which can send information to the UE through the base station.

[0054] The UE group can be one or more UEs divided by a network side device such as a core network based on data cooperation and the like.

[0055] The UEs in the same UE group can be UEs required to respond to paging within the same time period, and the UEs in the same UE group can be UEs required to be paged within the same time period. For example, the UEs in the same UE group are UEs required to be paged and woken up at the same time.

[0056] Here, the paging message can be a paging DCI, which can include scheduling information and a short message of paging content, and the UE can receive the paging content based on the scheduling information. The paging DCI can be transmitted using PDCCH resources. The first type of paging message can be a paging message sent to all UEs in the UE group. All UEs in the same UE group can listen to the first type of paging message at the same listening occasion. In this way, the UEs in the same UE group can be paged by the same paging message and respond based on the same paging message, for example, wake up at the same time. Further, the needs of the data fusion scenario under multi-modal can be met.

[0057] Different UE groups can be UE groups divided based on different data cooperation needs and the like. The first type of paging message of different UE groups can have different paging configurations, and here, the paging configuration can include transmission resources, and / or have different encoding methods, and / or have different group paging identities.

[0058] The first type of paging message for different UE groups can be different. The paging configuration of the first type of paging message for different UE groups can be different. The UE in different UE groups can receive the first type of paging message of the respective UE group. The paging configuration of different first type of paging message can be sent by the base station to the UE, and / or specified by the communication protocol, etc.

[0059] The UE can determine the first type of paging message that needs to be received according to the group paging identifier, and listen to and receive the first type of paging message at the listening occasion of the first type of paging message based on the paging configuration of the first type of paging message.

[0060] In this way, the base station sends the first type of paging message for the UE group, and the UE in the same UE group can respond based on the same first type of paging message. On the one hand, the efficiency of the base station paging UE is improved, and on the other hand, multiple UEs can respond to the paging message at the same time, meeting the requirements of data coordination and other communication services that require simultaneous wake-up.

[0061] In one embodiment, the UE included in the UE group is a multi-modal UE.

[0062] The information source and / or form received by the UE of different modalities is different. The UE in the same UE group can be different data sources in the data fusion process of a multi-modal data set. The UE in the same UE group is usually required to be data coordinated, such as uploading data at the same time, etc. For example, the UE in the same UE group can be multiple UEs that upload audio data, video data and environmental sensing data respectively in the data fusion process, and it is usually desired to obtain audio data, video data and environmental sensing data at the same time in the data fusion process.

[0063] The multi-modal UE includes a multi-modal input UE and / or a multi-modal output UE.

[0064] In one embodiment, the first type of paging message includes:

[0065] The first type of paging message for the idle state UE;

[0066] And / or,

[0067] The first type of paging message for the non-active state UE.

[0068] The UE in the same UE group can be in the same RRC state, or can be in different RRC states. For example, the UE in the same UE group can be in the RRC idle state or the RRC non-active state; some UEs in the same UE group can be in the RRC idle state, and the other UEs can be in the RRC non-active state, etc.

[0069] In one embodiment, the first type of paging message for the UE group comprises: a first type of paging message for a group paging identity of the UE group.

[0070] Different UE groups can be identified by different group paging identities. A UE can be configured with a group paging identity of a UE group to which the UE belongs. Thus, different group paging identities correspond to different first type of paging messages.

[0071] For example, a core network or a base station, etc. can divide UE groups according to data coordination needs, etc. and send corresponding group paging identities to UEs. Group paging identities can also be specified by communication protocols, etc.

[0072] The network device sends a first type of paging message for a UE group, i.e. a first type of paging message for a group paging identity.

[0073] In one embodiment, the UE group is determined according to the service of the UE;

[0074] and / or,

[0075] The UE group is determined according to the geographic location of the UE.

[0076] Here, the UE groups can be divided according to services. Here, UEs in the same UE group can handle the same service, such as the same service that needs to be coordinated for data.

[0077] For example, in a certain data coordination service, data collected by 3 different UEs need to be coordinated, for example, video data, audio data and temperature sensing data, respectively. Here, the 3 UEs can be divided into the same UE group, so that when the network device uses the first type of paging message to page, the responses of the 3 UEs can be kept consistent, realizing data coordination.

[0078] The service of a UE in the same UE group can also be multiple services that need to be coordinated for data.

[0079] In one embodiment, the core network can group UEs based on services. Since the core network can directly obtain the services of UEs, grouping UEs based on services by the core network can improve the grouping efficiency.

[0080] The UE groups can be divided according to geographic locations.

[0081] Here, the UE groups can be divided according to the geographic locations of UEs. Here, the geographic locations of UEs in the same UE group can be the same or different. The geographic locations of UEs in the same UE group can be selected according to the requirements of data coordination tasks.

[0082] For example, in a data collaboration task, the service data collected by n different UEs needs to be collaborated to obtain the service data statistical value in a larger range. Therefore, it is preferable that the n UEs are evenly distributed in the range. Therefore, the n UEs evenly distributed in the range can be selected to form a UE group. In this way, when the network device uses the first type of paging message for paging, the responses of the n UEs can be kept consistent, and data collaboration can be achieved.

[0083] In an embodiment, the UEs can be grouped by the base station based on the geographical positions of the UEs. Since the base station can directly obtain the geographical positions of the UEs, grouping the UEs based on the geographical positions of the UEs by the base station can improve the grouping efficiency.

[0084] In an embodiment, the paging configurations of the first type of paging messages of different UE groups are different.

[0085] The paging configuration can include a transmission resource, and / or a coding mode of paging, and / or a group paging identifier, etc.

[0086] The UEs of different UE groups receive the respective first type of paging messages using the respective paging configurations corresponding to the respective UE groups, which reduces the case that the UEs incorrectly receive the first type of paging messages of other UE groups due to the same paging configurations of the first type of paging messages of different UE groups, and further reduces the case of being incorrectly paged.

[0087] In an embodiment, the monitoring occasions of the first type of paging messages of different UE groups are different.

[0088] and / or,

[0089] The P-PRNTIs of the first type of paging messages of different UE groups are different.

[0090] and / or,

[0091] The CORESETs of the first type of paging messages of different UE groups are different.

[0092] and / or,

[0093] The search spaces of the first type of paging messages of different UE groups are different.

[0094] and / or,

[0095] The group paging identifiers carried by the first type of paging messages of different UE groups are different.

[0096] The paging configuration can include a monitoring occasion, a P-PRNTI, a CORESET, a search space, and / or a group paging identifier, etc.

[0097] The paging configuration of the first type of paging message of different UE groups is different, that is, the paging configuration of the first type of paging message corresponding to different group paging identifiers is different. The UE can determine the first type of paging that needs to be listened to and received according to the group paging identifier of the UE group to which the UE belongs.

[0098] For example, the UE can listen to the listening occasion of the first type of paging message corresponding to the group paging identifier of the UE group to which the UE belongs.

[0099] The network can configure the listening occasion bound to the group paging identifier, and the first type of paging message can not carry the identifier information associated with the UE group. The UE can only need to listen to the listening occasion corresponding to the UE group to which the UE belongs.

[0100] The first type of paging message can be scrambled by P-PRNTI. When the UE receives the paging message, if the blind detection of the first type of paging message scrambled by P-RNTI is successful, it can be judged that the first type of paging message is sent to itself.

[0101] The network can configure the P-RNTI bound to the UE group, that is, the group paging identifier. The UE in the same UE group can perform blind detection based on the P-RNTI corresponding to the UE group to which the UE belongs, so that the first type of paging message of the UE group to which the UE belongs can be received. That is, the UE can only listen to the first type of paging message corresponding to the P-RNTI bound to the UE group.

[0102] The CORESET is a set of transmission resources for transmitting the first type of paging message, including: frequency domain resources, and / or time domain resources, etc. Different first type of paging messages can use different CORESETs.

[0103] The network can configure the CORESET bound to the group paging identifier, and the UE listens to the first type of paging message based on the CORESET provided by the network. In this way, the first type of paging message will not carry UE group related identifier information, and the UE only needs to listen to the CORESET corresponding to the UE group.

[0104] The search space can define the start position and channel search method of blind detection of the first type of paging message, and different first type of paging messages can have different search spaces.

[0105] The network can configure the search space bound to the group paging identifier, and the UE listens to the first type of paging message based on the search space provided by the network. In this way, the first type of paging message will not carry UE group related identifier information, and the UE only needs to listen to the search space corresponding to the UE group.

[0106] The network can also set a group paging identity of the UE group in the first type of paging message of the UE group. In this way, the UE can determine whether the received first type of paging message is sent to itself according to the group paging identity in the first type of paging message.

[0107] In one embodiment, the network selects one or more of the above-mentioned monitoring occasions, monitoring occasions, P-PRNTIs, CORESET search spaces, and group paging identities for distinguishing different first type of paging messages. For example, the network can configure different first type of paging messages, different monitoring occasions, different monitoring occasions, different P-PRNTIs, different CORESET search spaces, and different group paging identities.

[0108] In some embodiments, as shown in Figure 2b The present disclosure provides a paging method, including:

[0109] Step 202: sending a second type of paging message for the UE.

[0110] The sending of the second type of paging message can be implemented alone or in combination with step 201.

[0111] The network device can send a second type of paging message for paging a single UE in addition to sending a first type of paging message.

[0112] The first type of paging message can be used to page a UE group, and the second type of paging message can be used to page a single UE.

[0113] In this way, the base station can send two types of paging messages, and the UE can receive two types of paging messages, improving the compatibility of the base station and the UE in transmitting paging messages.

[0114] In one embodiment, the paging configuration of the first type of paging message is different from the paging configuration of the second type of paging message.

[0115] The first type of paging message and the second type of paging message can have different paging configurations. Here, the paging configuration can include transmission resources, and / or different encoding methods, etc.

[0116] For example, the first type of paging message can carry an explicit indication for indicating that the first type of paging message is used to page a UE group. For example, the first type of paging message can indicate that the first type of paging message is used to page a UE group through a bit.

[0117] The UE can also perform monitoring of the second type of paging message while monitoring the first type of paging message in the PO corresponding to the group paging identity based on the group paging identity provided by the network;

[0118] For example, the UE can continue to monitor the second type of paging message outside the monitoring occasion of the first type of paging message. If the monitoring occasion of the first type of paging message and the monitoring occasion of the second type of paging message overlap, the UE can simultaneously decode the two types of paging messages.

[0119] For example, in a certain data coordination task, the data collected by 3 different UEs needs to be coordinated. Here, the 3 UEs can be divided into the same UE group, so that when the network device uses the first type of paging message to page, the responses of the 3 UEs can be consistent. The network device can also use the second type of paging message to page one or more of the 3 UEs, so as to maintain the normal development of other communication services outside the data coordination task.

[0120] In this way, the base station can send two types of paging messages, and the UE can receive two types of paging messages, thereby improving the compatibility of the base station and the UE in transmitting paging messages.

[0121] In one embodiment, the monitoring occasion of the first type of paging message is different from the monitoring occasion of the second type of paging message.

[0122] And / or,

[0123] The P-PRNTI of the first type of paging message is different from the P-PRNTI of the second type of paging message.

[0124] And / or,

[0125] The CORESET of the first type of paging message is different from the CORESET of the second type of paging message.

[0126] And / or,

[0127] The search space of the first type of paging message is different from the search space of the second type of paging message.

[0128] The first type of paging message and the second type of paging message can have different paging configurations. Here, the paging configuration can include: transmission resource, and / or different encoding method, etc.

[0129] For example, the monitoring occasion of the first type of paging message is different from the monitoring occasion of the second type of paging message. The network device can send the first type of paging message and the second type of paging message in different monitoring occasions, and the UE can receive the first type of paging message and the second type of paging message in different monitoring occasions. In this way, the complexity of receiving paging messages caused by the overlap of the monitoring occasions of the two types of paging messages is reduced.

[0130] The first type of paging message and the second type of paging message can be scrambled by different P-PRNTIs. When the UE receives the paging message, the UE can blind detect the paging message by using the P-PRNTI corresponding to the first type of paging message and the P-PRNTI corresponding to the second type of paging message, and then receive the first type of paging message or the second type of paging message sent to the UE.

[0131] The network device can transmit the first type of paging message and the second type of paging message by using different CORESETs. When the UE receives the paging message, the UE can receive by using the CORESET corresponding to the first type of paging message and the CORESET corresponding to the second type of paging message, and then receive the first type of paging message or the second type of paging message sent to the UE.

[0132] The network device can transmit the first type of paging message and the second type of paging message by using different search spaces. When the UE receives the paging message, the UE can listen by using the search space corresponding to the first type of paging message and the search space corresponding to the second type of paging message, and then receive the first type of paging message or the second type of paging message sent to the UE.

[0133] In an embodiment, the network selects one or more of the above-mentioned listening occasions, listening occasions, P-PRNTIs, CORESETs, search spaces, and group paging identifiers to distinguish between the different first type of paging message and the second type of paging message. For example, the network can configure the first type of paging message and the second type of paging message, wherein the listening occasions, listening occasions, P-PRNTIs, CORESETs, and search spaces of the first type of paging message and the second type of paging message are all different.

[0134] In some embodiments, as shown in FIG. 2, the present disclosure provides a paging method comprising: Figure 2c

[0135] Step 203: sending a listening indication to the UE, wherein the listening indication indicates that the UE listens to the first type of paging message and / or the second type of paging message.

[0136] The sending of the listening indication can be implemented alone or in combination with the step 201 and / or the step 202. The UE can listen to the first type of paging message and / or the second type of paging message based on the indication of the network listening indication or the provision of the communication protocol.

[0137] For example, the UE can listen to the first type of paging message and / or the second type of paging message based on the indication of the network listening indication or the provision of the communication protocol.

[0138] For example, the UE can listen to the first type of paging message and / or the second type of paging message based on the indication of the network listening indication or the provision of the communication protocol.

[0139] ​In an embodiment, the base station can send the listening indication to the UE in a broadcast message such as a system message. For example, the listening indication can be sent to the UE in a broadcast message such as a system message, indicating that the UE needs to listen to the first type of paging message.

[0140] In some embodiments, as shown in Figure 2d The present disclosure provides a paging method, including:

[0141] Step 204a: sending, by the network device, identification indication information indicating a group paging identifier of a UE group to which the UE belongs;

[0142] And / or,

[0143] Step 204b: sending, by an access network device in the network device, paging configuration information indicating a paging configuration of the first type of paging message.

[0144] Step 204a and / or step 204b can be implemented alone or in combination with step 201, step 202 and / or step 203.

[0145] Here, the UE can be grouped by the core network or the access network device, and the paging configuration information of the first type of paging message of each UE group can be determined by the access network device. The paging configuration information is used to indicate the paging configuration of the first type of paging, such as transmission resource, and / or different encoding mode, and / or different group paging identifier, etc.

[0146] The core network or the access network device can send the group paging identifier indication information of the UE group to which the UE belongs to the UE, so that the UE can determine the group paging identifier according to the group paging identifier indication information, and further determine the UE group to which the UE belongs according to the group paging identifier.

[0147] The access network device can send the paging configuration information to the UE. The paging configuration information can indicate the paging configuration of the first type of paging message of the UE group to which the UE belongs, or can indicate the paging configuration of the first type of paging message of all UE groups. In this way, the UE can receive the first type of paging message according to the group paging identifier and the paging configuration.

[0148] The identification indication information and the paging configuration information provided by the network can be sent to the UE through public signaling or dedicated signaling.

[0149] In an embodiment, in response to the UE receiving the identification indication information indicating the group paging identifier, at least the first type of paging message is received.

[0150] If the network device allocates a group paging identifier to the UE, it means that the UE needs to at least listen to the first type of paging message.

[0151] In an embodiment, the sending of the identity indication information indicating the group paging identity of the UE group to which the UE belongs comprises at least one of:

[0152] sending access stratum (AS) information carrying the identity indication information;

[0153] sending non-access stratum (NAS) information carrying the identity indication information;

[0154] The sending, by the access network device in the network device, of the paging configuration information indicating the paging configuration of the first type of paging message comprises:

[0155] sending, by the access network device, AS information carrying the paging configuration information.

[0156] If the identity indication information and / or the paging configuration information are determined by a radio access layer device, the AS information can be sent directly to the UE by a RNC or a base station or the like.

[0157] If the identity indication information is determined by a core network device, the NAS information can be sent directly to the UE by the core network device. In this way, the access of the access layer device is reduced, and the communication efficiency is improved. The identity indication information can be determined by the core network, and the identity indication information is forwarded to the UE by the base station.

[0158] In an embodiment, the AS information comprises:

[0159] system information;

[0160] RRC signaling.

[0161] In an embodiment, the base station sends system information carrying the identity indication information and / or the paging configuration information, and the UE parses the identity indication information and / or the paging configuration information from the system information.

[0162] Alternatively, the base station sends RRC signaling carrying the identity indication information and / or the paging configuration information, and the UE parses the identity indication information and / or the paging configuration information from the RRC signaling. Since the UE receives the RRC signaling in an RRC connected state, the identity indication information and the paging configuration information can respectively indicate the group paging identity and the paging configuration of the UE in an RRC non-connected state. Here, the RRC non-connected state comprises an RRC idle state and / or an RRC inactive state.

[0163] Exemplarily, the access network device such as a base station can send the identification indication information and / or the paging configuration information carried in AS information. The group paging identifier indicating the UE group to which the UE belongs, and the paging configuration of the first type of paging message. Here, the AS information can be RRC signaling such as RRC release signaling. After receiving the identification indication information and / or the paging configuration information, the UE listens to the first type of paging message based on the allocated group paging identifier and the paging configuration of the first type of paging message.

[0164] In one embodiment, the NAS information includes:

[0165] Downlink information in the UE attachment process.

[0166] Here, the core network can carry the identification indication information and / or the paging configuration information in the downlink information during the attachment process of the UE. The NAS layer of the UE can notify the AS layer of the identification indication information and / or the paging configuration information through an interlayer message, and then perform the first type of paging message.

[0167] Exemplarily, the core network can send the identification indication information, i.e., the core network notifies the UE of its group paging identifier in the attachment message.

[0168] As an embodiment, the core network carries the UE group paging identifier in the paging message sent to the base station.

[0169] As an embodiment, the core network carries the group paging identifier indication information in the paging message sent to the base station, indicating that this is a group paging.

[0170] As an embodiment, the base station determines that this is a group paging, and sends the paging configuration of the group paging identifier to the first type of paging message.

[0171] As an embodiment, if the UE is in an idle state, the UE notifies the upper layer after receiving the first type of paging message.

[0172] In some embodiments, as shown in the figure, Figure 2e The embodiment of the present disclosure provides a paging method including:

[0173] Step 205: Send listening period indication information indicating the valid time period of the first type of paging message.

[0174] Step 205 can be implemented alone or in combination with step 201, step 202, step 203, step 204a and / or step 204b.

[0175] The network side can notify the UE that it can listen to and accept the first type of paging message within the valid time period. Outside the valid time period, the UE can not listen to the first type of paging message, but only listen to the second type of paging message.

[0176] In one embodiment, the UE can listen to and accept the first type of paging message and the second type of paging message within a valid time period.

[0177] As an embodiment, if the UE is in an idle state, the UE informs a higher layer after receiving the first type of paging message.

[0178] In some embodiments, as shown in Figure 2f The embodiments of the present disclosure provide a paging method, comprising:

[0179] Step 206: Based on the paging message receiving capability of the UE, the first type of paging message and / or the second type of paging message is sent to the UE.

[0180] Step 206 can be implemented alone or in combination with step 201, step 202, step 203, step 204a, step 204b and / or step 205.

[0181] For example, if the UE has the capability of simultaneously listening to and receiving the first type of paging message and the second type of paging message, the network device can send the first type of paging message and the second type of paging message, or can also send only one of the first type of paging message and the second type of paging message.

[0182] If the UE only has the capability of simultaneously listening to and receiving one of the first type of paging message and the second type of paging message, the network device can only send one of the first type of paging message and the second type of paging message.

[0183] Here, the capability of the UE to listen to and receive the first type of paging message can be the capability of listening to and receiving Group PDCCH DCI. The capability of the UE to listen to and receive the second type of paging message can be the capability of receiving other PDCCH DCI, etc.

[0184] In one embodiment, the method further comprises:

[0185] Receiving the capability indication information sent by the UE, wherein the capability indication information indicates the paging message receiving capability of the UE.

[0186] The UE can indicate the capability of the UE to receive the paging message to the network side.

[0187] For example, the UE can indicate the capability of the UE to receive the paging message by sending the capability indication information to the network device.

[0188] For example, the UE can carry the UE capability indication information on the capability information to the base station. The information can be forwarded to the core network by the base station. For example, the information can be forwarded to the core network by the base station when releasing the UE.

[0189] As Figure 3a shown, the present exemplary embodiment provides a paging method, which can be performed by a UE of a cellular mobile communication system, comprising:

[0190] Step 301: receiving a first type of paging message of a UE group to which the UE belongs, wherein the UE group comprises at least one UE.

[0191] The UE can be a mobile terminal or the like that performs wireless communication using a cellular mobile communication technology. The network device can be a base station or the like of a cellular mobile communication system.

[0192] The UE group can be one or more UEs divided by a network device such as a core network based on a data coordination requirement or the like.

[0193] The UEs in the same UE group can be UEs required to respond to paging within the same time period, such as the UEs in the same UE group can be UEs required to be paged within the same time period. For example, the UEs in the same UE group are UEs required to be paged and woken up at the same time.

[0194] Here, the paging message can be a paging DCI, which can include scheduling information and a short message of paging content or the like, and the UE can receive the paging content based on the scheduling information. The paging DCI can be transmitted using PDCCH resources. The first type of paging message can be a paging message sent to all UEs in the UE group. All UEs in the same UE group can listen to the first type of paging message at the same listening occasion. In this way, the UEs in the same UE group can be paged by the same paging message and respond based on the same paging message, such as waking up at the same time. Further, the requirements of the data fusion scene in the multi-modal can be met.

[0195] Different UE groups can be UE groups divided based on different data coordination requirements or the like. The first type of paging message of different UE groups can have different paging configurations, here, the paging configuration can include: transmission resources, and / or have different encoding methods, and / or have different group paging identifiers, etc.

[0196] The first type of paging message of different UE groups can be different, which can include: the paging configuration of the first type of paging message of different UE groups can be different. The UEs of different UE groups can receive the first type of paging message of their respective UE groups. The paging configuration of different first type of paging messages can be sent to the UE by the base station, and / or specified by the communication protocol or the like.

[0197] The UE can determine the first type of paging message that needs to be received according to the group paging identifier, and listen to and receive the first type of paging message at the listening occasion of the first type of paging message based on the paging configuration of the first type of paging message.

[0198] Thus, the base station sends the first type of paging message for the UE group, and the UEs in the same UE group can wake up and respond based on the same first type of paging message, on the one hand, improving the efficiency of the base station paging UEs, and on the other hand, realizing that multiple UEs can respond to the paging message at the same time, meeting the requirements of data cooperation and other communication services that require simultaneous wake-up.

[0199] In an embodiment, the UE is a multi-modal UE.

[0200] The information sources and / or forms received by UEs of different modalities are different. The UEs in the same UE group can be different data sources in the data fusion process of a multi-modal data set. The UEs in the same UE group are usually required to cooperate in data, such as uploading data at the same time. For example, the UEs in the same UE group can be multiple UEs that upload audio data, video data, and environmental sensing data in a data fusion process, respectively. In the data fusion process, it is usually desired to obtain audio data, video data, and environmental sensing data at the same time.

[0201] The multi-modal UE includes a multi-modal input UE and / or a multi-modal output UE.

[0202] In an embodiment, the UE is in an idle state or an active state.

[0203] The UEs in the same UE group can be in the same RRC state or in different RRC states. For example, the UEs in the same UE group can all be in an RRC idle state or an RRC inactive state; some UEs in the same UE group can be in an RRC idle state, and the other UEs can be in an RRC inactive state, and so on.

[0204] In an embodiment, the receiving the first type of paging message for the UE group to which the UE belongs includes:

[0205] Receiving the first type of paging message for the group paging identifier of the UE group.

[0206] Different UE groups can be identified by different group paging identifiers. A UE can be configured with a group paging identifier of a UE group to which the UE belongs. Thus, different group paging identifiers correspond to different first type of paging messages.

[0207] For example, a core network or a base station, etc. can divide UE groups according to data cooperation requirements, etc. and send corresponding group paging identifiers to UEs. The group paging identifier can also be specified by a communication protocol, etc.

[0208] The network device sends the first type of paging message for the UE group, i.e., the first type of paging message for the group paging identifier.

[0209] In an embodiment, the UE groups are determined according to services of the UEs.

[0210] and / or,

[0211] The UE groups are determined according to geographic locations of the UEs.

[0212] Here, the UE groups can be divided according to services. Here, the UEs in the same UE group can process the same service, such as the same service requiring data coordination.

[0213] For example, in a certain data coordination service, data collected by three different UEs, such as video data, audio data, and temperature sensing data, need to be coordinated. Here, the three UEs can be divided into the same UE group, so that the responses of the three UEs can be consistent when the network device uses the first type of paging message for paging, and data coordination can be achieved.

[0214] The services of the UEs in the same UE group can also be multiple services requiring data coordination.

[0215] The UE groups can be divided according to geographic locations.

[0216] Here, the UE groups can be divided according to geographic locations of the UEs. Here, the geographic locations of the UEs in the same UE group can be the same or different. The geographic locations of the UEs in the same UE group can be selected according to requirements of a data coordination task.

[0217] For example, in a certain data coordination task, service data collected by n different UEs need to be coordinated to obtain service data statistical values in a larger range. Therefore, it is preferable that the n UEs are evenly distributed in the range. Therefore, n UEs evenly distributed in the range can be selected to form a UE group. Thus, when the network device uses the first type of paging message for paging, the responses of the n UEs can be consistent, and data coordination can be achieved.

[0218] In an embodiment, the paging configurations of the first type of paging messages of different UE groups are different.

[0219] The paging configuration can include a transmission resource, and / or a coding mode of paging, and / or a group paging identifier, etc.

[0220] The UEs in different UE groups receive the respective first type of paging messages using the respective paging configurations corresponding to the respective UE groups, thereby reducing the case that the UEs incorrectly receive the first type of paging messages of other UE groups due to the paging configurations of the first type of paging messages of different UE groups being the same, and further reducing the case of being incorrectly paged.

[0221] In an embodiment, the listening occasions of the first type of paging messages of different UE groups are different.

[0222] and / or,

[0223] the paging radio network temporary identity (P-RNTI) of the first type of paging message is different for different UE groups;

[0224] and / or,

[0225] the control resource set (CORESET) of the first type of paging message is different for different UE groups;

[0226] and / or,

[0227] the search space of the first type of paging message is different for different UE groups;

[0228] and / or,

[0229] the group paging identity carried by the first type of paging message is different for different UE groups.

[0230] The paging configuration can include a monitoring occasion, a P-RNTI, a CORESET, a search space, and / or a group paging identity, etc.

[0231] The paging configuration of the first type of paging message is different for different UE groups, i.e., the paging configuration of the first type of paging message corresponding to different group paging identities is different. The UE can determine the first type of paging that needs to be monitored and received according to the group paging identity of the UE group to which the UE belongs.

[0232] For example, the UE can monitor the monitoring occasion of the first type of paging message corresponding to the group paging identity of the UE group to which the UE belongs.

[0233] The network can configure a monitoring occasion bound to a group paging identity, and the first type of paging message can not carry the identification information associated with the UE group. The UE can only need to monitor at the monitoring occasion corresponding to the UE group to which the UE belongs.

[0234] The first type of paging message can be scrambled by a P-RNTI. When the UE receives the paging message, if the blind detection of the first type of paging message scrambled by the P-RNTI is successful, it can be judged that the first type of paging message is sent to itself.

[0235] The network can configure a P-RNTI bound to a UE group, i.e., a group paging identity, and the UE in the same UE group can perform blind detection based on the P-RNTI corresponding to the UE group to which the UE belongs, so that the UE can receive the first type of paging message of the UE group to which the UE belongs. That is, the UE can only monitor the first type of paging message corresponding to the P-RNTI bound to the UE group to which the UE belongs.

[0236] The CORESET is a set of transmission resources for transmitting the first type of paging message, including: frequency domain resources, and / or time domain resources, etc. Different first type of paging messages can adopt different CORESETs.

[0237] The network can configure a CORESET bound to the group paging identifier, and the UE monitors the first type of paging message based on the CORESET provided by the network. In this way, the UE group related identifier information will not be carried in the first type of paging message, and the UE only needs to monitor the CORESET corresponding to its own UE group.

[0238] The search space can define the starting position and channel search method of blind detection of the first type of paging message, and different first type of paging messages can have different search spaces.

[0239] The network can configure a search space bound to the group paging identifier, and the UE monitors the first type of paging message based on the search space provided by the network. In this way, the UE group related identifier information will not be carried in the first type of paging message, and the UE only needs to monitor the search space corresponding to its own UE group.

[0240] The network can also set the group paging identifier of the UE group in the first type of paging message of the UE group. In this way, the UE can determine whether the received first type of paging message is sent to itself according to the group paging identifier in the first type of paging message.

[0241] In one embodiment, the network selects one or more of the above-mentioned monitoring occasions, monitoring occasions, P-PRNTIs, CORESET search spaces, and group paging identifiers to distinguish different first type of paging messages. For example, the network can configure different first type of paging messages, and the monitoring occasions, monitoring occasions, P-PRNTIs, CORESET search spaces, and group paging identifiers are all different.

[0242] In some embodiments, as shown in Figure 3b The present disclosure provides a paging method, including:

[0243] Step 302: receiving a second type of paging message for the UE.

[0244] Step 302 can be implemented alone or in combination with step 301.

[0245] In addition to sending the first type of paging message, the network device can also send a second type of paging message for paging a single UE.

[0246] The first type of paging message can be used to page a UE group, and the second type of paging message can be used to page a single UE.

[0247] Thus, the base station can send two types of paging messages, and the UE can receive two types of paging messages, improving the compatibility of the base station and the UE in transmitting paging messages.

[0248] In one embodiment, the paging configuration of the first type of paging message is different from the paging configuration of the second type of paging message.

[0249] The first type of paging message and the second type of paging message can have different paging configurations. Here, the paging configuration can include: transmission resources, and / or different encoding methods, etc.

[0250] The UE can listen to the second type of paging message while listening to the first type of paging message in the PO corresponding to the group paging identifier provided by the network.

[0251] For example, the UE can continue to listen to the second type of paging message outside the listening occasion of the first type of paging message. If the listening occasion of the first type of paging message and the listening occasion of the second type of paging message overlap, the UE can simultaneously decode the two types of paging messages.

[0252] For example, in a certain data coordination task, the data collected by 3 different UEs needs to be coordinated. Here, the 3 UEs can be divided into the same UE group, so that when the network device uses the first type of paging message to page, the responses of the 3 UEs can be kept consistent. The network device can also use the second type of paging message to page one or more of the 3 UEs, so as to maintain the normal development of other communication services outside the data coordination task.

[0253] Thus, the base station can send two types of paging messages, and the UE can receive two types of paging messages, improving the compatibility of the base station and the UE in transmitting paging messages.

[0254] In one embodiment, the listening occasion of the first type of paging message is different from the listening occasion of the second type of paging message.

[0255] And / or,

[0256] The P-PRNTI of the first type of paging message is different from the P-PRNTI of the second type of paging message.

[0257] And / or,

[0258] The CORESET of the first type of paging message is different from the CORESET of the second type of paging message.

[0259] And / or,

[0260] The search space of the first type of paging message is different from the search space of the second type of paging message.

[0261] The first type of paging message and the second type of paging message can have different paging configurations, where the paging configuration can include: transmission resources, and / or different encoding methods, etc.

[0262] For example, the listening occasions of the first type of paging message and the second type of paging message are different, and the network device can send the first type of paging message and the second type of paging message at different listening occasions, and the UE can receive the first type of paging message and the second type of paging message at different listening occasions. In this way, the complexity of receiving paging messages caused by the overlap of the listening occasions of the two types of paging messages is reduced.

[0263] The network device can scramble the first type of paging message and the second type of paging message using different P-PRNTIs. When the UE receives the paging message, it can use the P-PRNTI corresponding to the first type of paging message and the second type of paging message to blindly detect the paging message, and then receive the first type of paging message or the second type of paging message sent to itself.

[0264] The network device can transmit the first type of paging message and the second type of paging message using different CORESETs. When the UE receives the paging message, it can use the CORESET corresponding to the first type of paging message and the second type of paging message to receive, and then receive the first type of paging message or the second type of paging message sent to itself.

[0265] The network device can transmit the first type of paging message and the second type of paging message using different search spaces. When the UE receives the paging message, it can use the search space corresponding to the first type of paging message and the second type of paging message to listen, and then receive the first type of paging message or the second type of paging message sent to itself.

[0266] In one embodiment, the network selects one or more of the above-mentioned listening occasions, listening occasions, P-PRNTIs, CORESETs, search spaces, and group paging identifiers to distinguish between different first type of paging messages and second type of paging messages. For example, the network can configure the first type of paging message and the second type of paging message, where the listening occasions, listening occasions, P-PRNTIs, CORESETs, and search spaces of the first type of paging message and the second type of paging message are all different.

[0267] In some embodiments, as Figure 3c shown, the present disclosure provides a paging method comprising:

[0268] Step 303: receiving a listening indication; based on the listening indication, listening to the first type of paging message and / or the second type of paging message.

[0269] The step 303 can be implemented alone or in combination with the step 301 and / or the step 302.

[0270] The UE can listen to the first type of paging message and / or the second type of paging message based on the indication of the network listening indication or the provision of the communication protocol.

[0271] For example, the UE can listen to the first type of paging message and / or the second type of paging message based on the indication of the network listening indication or the provision of the communication protocol.

[0272] The UE can listen to only the first type of paging message or the second type of paging message based on the indication of the network listening indication or the provision of the communication protocol.

[0273] In an embodiment, the base station can send the listening indication to the UE in a broadcast message such as a system message. For example, the listening indication can be sent to the UE in a broadcast message such as a system message, indicating that the UE listens to the first type of paging message.

[0274] In some embodiments, as shown in Figure 3d The present disclosure provides a paging method, including:

[0275] Step 304: receiving identification indication information indicating a group paging identifier of a UE group to which the UE belongs and / or paging configuration information indicating paging configuration of the first type of paging message.

[0276] The step 304 can be implemented alone or in combination with the step 301, the step 302 and / or the step 303.

[0277] Here, the UE can be grouped by a core network or an access network device, etc. The access network device determines the paging configuration information of the first type of paging message of each UE group. The paging configuration information is used to indicate the paging configuration of the first type of paging, such as transmission resource, and / or different encoding mode, and / or different group paging identifier, etc.

[0278] The core network or the access network device can send the group paging identifier indication information of the UE group to the UE. In this way, the UE can determine the group paging identifier according to the group paging identifier indication information, and further determine the UE group to which the UE belongs according to the group paging identifier.

[0279] The access network device can send the paging configuration information to the UE. The paging configuration information can indicate the paging configuration of the first type of paging message of the UE group to which the UE belongs, or can indicate the paging configuration of the first type of paging message of all UE groups. In this way, the UE can receive the first type of paging message according to the group paging identifier and the paging configuration.

[0280] The identity indication information and the paging configuration information provided by the network can be sent to the UE through common signaling or dedicated signaling.

[0281] In one embodiment, in response to the UE receiving the identity indication information indicating the group paging identity, at least the first type of paging message is received.

[0282] If the network device allocates a group paging identity for the UE, it means that the UE needs to at least monitor the first type of paging message.

[0283] In one embodiment, the receiving of the identity indication information indicating the group paging identity of the UE group to which the UE belongs and / or the paging configuration information indicating the paging configuration of the first type of paging message comprises at least one of the following:

[0284] Receiving access stratum (AS) information carrying the identity indication information and / or the paging configuration information;

[0285] Receiving non-access stratum (NAS) information carrying the identity indication information.

[0286] If the identity indication information and / or the paging configuration information are determined by a radio access layer device, they can be sent to the UE directly by the RNC or the base station and the like through AS information.

[0287] If the identity indication information is determined by a core network device, it can be sent to the UE directly by the core network device through NAS information. In this way, the access of the access layer device is reduced, and the communication efficiency is improved. The identity indication information can be determined by the core network, and the identity indication information is forwarded to the UE by the base station.

[0288] In one embodiment, the AS information comprises:

[0289] System message;

[0290] RRC signaling.

[0291] In one embodiment, the base station sends a system message carrying the identity indication information and / or the paging configuration information, and the UE parses the identity indication information and / or the paging configuration information from the system message.

[0292] Alternatively, the base station sends RRC signaling carrying the identity indication information and / or the paging configuration information, and the UE parses the identity indication information and / or the paging configuration information from the RRC signaling. Since the UE receives the RRC signaling in the RRC connected state, the identity indication information and the paging configuration information can respectively indicate the group paging identity and the paging configuration of the UE in the RRC non-connected state. Here, the RRC non-connected state includes the RRC idle state and / or the RRC inactive state.

[0293] Exemplarily, the access network device such as a base station can send the identification indication information and / or the paging configuration information carried in AS information. The group paging identifier indicating the UE group to which the UE belongs, and the paging configuration of the first type of paging message. Here, the AS information can be RRC signaling such as RRC release signaling. After receiving the identification indication information and / or the paging configuration information, the UE listens to the first type of paging message based on the allocated group paging identifier and the paging configuration of the first type of paging message.

[0294] In one embodiment, the NAS information includes:

[0295] Downlink information in the UE attachment process.

[0296] Here, the core network can carry the identification indication information and / or the paging configuration information in the downlink information during the attachment process of the UE. The NAS layer of the UE can notify the AS layer of the identification indication information and / or the paging configuration information through interlayer messages, and then perform the first type of paging message.

[0297] Exemplarily, the core network can send the identification indication information, i.e., the core network notifies the UE of its group paging identifier in the attachment message.

[0298] As an embodiment, the core network carries the UE group paging identifier in the paging message sent to the base station.

[0299] As an embodiment, the core network carries the group paging identifier indication information in the paging message sent to the base station, indicating that this is a group paging.

[0300] As an embodiment, the base station determines that this is a group paging, and sends the paging configuration of the group paging identifier to the first type of paging message.

[0301] As an embodiment, if the UE is in an idle state, the UE notifies the upper layer after receiving the first type of paging message.

[0302] In some embodiments, as shown in Figure 3e The present disclosure provides a paging method, including:

[0303] Step 305: receiving listening period indication information indicating a valid time period of the first type of paging message;

[0304] The receiving the first type of paging message of the UE group to which the UE belongs includes:

[0305] Receiving the first type of paging message within the valid time period. Step 305 can be implemented alone or in combination with steps 301, 302, 303, and / or 304.

[0306] In an embodiment, the method further comprises:

[0307] The network side can inform the UE that the UE can listen to and accept the first type of paging message within a valid time period. Outside the valid time period, the UE can not listen to the first type of paging message, but only listen to the second type of paging message.

[0308] In an embodiment, the UE can listen to and accept the first type of paging message and the second type of paging message within the valid time period.

[0309] In some embodiments, as Figure 3f shown, the embodiment of the present disclosure provides a paging method comprising:

[0310] Step 306: transmitting the capability indication information, wherein the capability indication information indicates the paging message receiving capability of the UE.

[0311] Step 306 can be implemented alone or in combination with step 301, step 302, step 303, step 304 and / or step 305.

[0312] For example, if the UE has the capability of simultaneously listening to and receiving the first type of paging message and the second type of paging message, the network device can transmit the first type of paging message and the second type of paging message, or can also transmit only one of the first type of paging message and the second type of paging message.

[0313] If the UE only has the capability of simultaneously listening to and receiving one of the first type of paging message and the second type of paging message, the network device can only transmit one of the first type of paging message and the second type of paging message.

[0314] Here, the capability of the UE to listen to and receive the first type of paging message can be the capability of listening to and receiving Group PDCCH DCI. The capability of the UE to listen to and receive the second type of paging message can be the capability of receiving other PDCCH DCI, etc.

[0315] The UE can indicate the capability of the UE to receive the paging message to the network side.

[0316] For example, the UE can indicate the capability of the UE to receive the paging message by transmitting the capability indication information to the network device.

[0317] For example, the UE can report the UE capability indication information to the base station on the capability information. The information can be forwarded to the core network by the base station.

[0318] In some embodiments, as Figure 3g shown, the embodiment of the present disclosure provides a paging method comprising at least one of the following:

[0319] Step 307a: forwarding the paging notification information carrying the group paging identifier of the UE group to the UE high layer in response to the UE being in idle state and receiving the first type of paging message;

[0320] Step 307b: resuming to connected state in response to the UE being in inactive state and receiving the first type of paging message;

[0321] Step 307c: performing non-access layer recovery in response to the UE being in inactive state and receiving the first type of paging message for idle state.

[0322] Step 307a, step 307b and / or step 307c can be implemented alone or in combination with step 301, step 302, step 303, step 304, step 305 and / or step 306.

[0323] For the received first type of paging message, the idle state UE can carry the UE group information when sending the paging notification information to the NAS, and here the UE group information can include: group paging identifier. The high layer can determine that the paging message for the UE group is received. Here, the first type of paging message can be initiated by the base station for the idle state user. For the received first type of paging message, the inactive state UE can resume to the connected state.

[0324] If the inactive state UE receives the group first type of paging message for idle state, the response mode of the inactive state UE can include: performing non-access layer recovery (NAS recovery);

[0325] The following provides a specific example in combination with any of the above embodiments:

[0326] 1. For the newly added application scenario in the network that needs to be synchronized in groups, increase the paging coordination processing.

[0327] a) As an embodiment: the user who needs to be synchronized in groups is a multi-modal output terminal.

[0328] b) The application scenario is idle state / inactive state / connected state.

[0329] As a preferred embodiment: the network performs group coordinated paging for idle state users.

[0330] As a preferred embodiment: the network performs group coordinated paging for inactive state users.

[0331] 2, based on 1, the terminal performs group paging message listening based on the group paging identifier provided by the network.

[0332] a) As an embodiment: the group paging identifier can be grouped according to the service.

[0333] As an embodiment: the core network groups the terminals according to the service characteristics. Because the core network is more aware of the service characteristics.

[0334] b) As an embodiment: the Group Paging Identity can be grouped according to the geographical location.

[0335] As an embodiment: the base station groups the terminals according to the geographical location of the terminals. Because the base station is more aware of the location of the terminals.

[0336] 3. Based on 2, the terminal decodes and receives the group paging message based on the Group Paging Identity provided by the network, i.e. different UE groups are distinguished by different time-frequency codes:

[0337] a) As an embodiment: the terminal listens based on the specific listening moment provided by the network and bound to the Group Paging Identity.

[0338] Further: the network can provide the specific listening moment bound to the Group Paging Identity one-to-one, then the UE group information will not be carried in the paging message.

[0339] Further: the network can provide the specific listening moment bound to the Group Paging Identity as a listening moment different from the legacy listening moment.

[0340] b) As an embodiment: the terminal listens based on the specific PRNTI provided by the network and bound to the Group Paging Identity.

[0341] Further: the network can provide the specific PRNTI bound to the Group Paging Identity one-to-one, then the UE group information will not be carried in the paging message. For example, the terminal only needs to listen to the specific PRNTI corresponding to its own UE group.

[0342] Further: the network can provide the specific PRNTI bound to the Group Paging Identity as a PRNTI different from the legacy listening moment.

[0343] c) As an embodiment: the terminal listens based on the specific CORESET provided by the network and bound to the Group Paging Identity.

[0344] Further: the network can provide the specific CORESET bound to the Group Paging Identity one-to-one, then the UE group information will not be carried in the paging message. The terminal only needs to listen to the specific CORESET corresponding to its own UE group.

[0345] Further more: the network can provide the specific CORESET for the Group Paging ID binding to be different from the legacy monitoring CORESET.

[0346] d) As an embodiment: the terminal monitors based on the specific search space provided by the network and the Group Paging ID binding.

[0347] Further more: the network can provide the specific search space for the Group Paging ID binding to be one-to-one corresponding, then the UE group information will not be carried in the paging message. The terminal only needs to monitor the specific search space corresponding to its own UE group.

[0348] Further more: the network can provide the specific search space for the Group Paging ID binding to be different from the legacy monitoring search space.

[0349] e) As an embodiment: the terminal monitors based on the Group Paging ID provided by the network.

[0350] Further more: the network does not provide the different time-frequency codes in abcd to distinguish different UE groups, then the group ID can be provided in the paging message to distinguish.

[0351] As an embodiment, an indication is provided in the paging message to indicate that it is a group type of paging.

[0352] 4, based on 2, the terminal needs to monitor the PO binding to the Group Paging ID provided by the network based on the Group Paging ID provided by the network, and can also monitor the legacy paging message.

[0353] a) As an embodiment: if the network provides the group paging to be monitored at a specific monitoring moment, the terminal can continue to monitor the legacy paging in addition to monitoring the group paging, that is, both monitoring moments need to be monitored.

[0354] b) As an embodiment: if the specific monitoring moment of the network provided group paging and the legacy monitoring moment overlap, the terminal can simultaneously decode the two kinds of paging messages.

[0355] 5, based on 2, the terminal can perform the monitoring behavior based on the network notification or protocol pre-agreement:

[0356] a) As an embodiment: based on the network notification or protocol pre-agreement to monitor the two kinds of paging messages.

[0357] b) As an embodiment: the network allocates a group paging ID to the terminal, which means that the terminal needs to at least monitor the group paging message.

[0358] c) As an embodiment: only group paging message monitoring based on network notification or protocol pre-agreement.

[0359] For example: the base station sends a broadcast message to notify the terminal with group paging monitoring capability to start the group paging monitoring function.

[0360] 6. Based on 2, the terminal's processing for receiving group paging message monitoring:

[0361] a) For receiving group paging messages, idle state users will notify the upper layer, which can carry group information.

[0362] b) For receiving group paging messages, non-active state will perform resume process.

[0363] c) For receiving idle state group paging messages, non-active state will perform NAS recovery.

[0364] 7. As an embodiment: the network provides group paging identifier and group paging configuration, which can be notified to the user in advance through public signaling or dedicated signaling.

[0365] a) As an embodiment: this information can be notified to the terminal at the AS level, one possibility is to notify the user through system message.

[0366] b) As an embodiment: this information can be notified to the terminal at the AS level, one possibility is to notify the user through RRC connection release message, and additional effective conditions can also be added.

[0367] For example, the non-active state UE group paging identifier is allocated to the active state user.

[0368] For example: at this time, the network is an access network element, such as a base station;

[0369] As an embodiment, the base station groups UE1 and UE2 for group paging, that is, the base station notifies UE1 and UE2 in the release message that the group paging identifier is group1. And notify the terminal of the paging configuration of Group1.

[0370] As an embodiment, UE1 and UE2 will monitor the group paging information under the paging configuration of Group1.

[0371] As an embodiment, the paging message sent by the base station carries the UE group paging identifier, that is, Group1 group.

[0372] As an embodiment, if UE1 and UE2 are in non-active state, send Resume request to the network.

[0373] Further, inform the UE that the UE group is valid, i.e. the UE can only be paged by the legacy paging outside the validity period.

[0374] c) As an embodiment, the information can be informed to the terminal at the NAS level, and one possibility is that the Attach procedure of the UE informs the user.

[0375] Further, the NAS layer of the terminal can inform the AS layer of the home UE group information through an interlayer message for paging message monitoring.

[0376] Example: At this time, the network is a core network element;

[0377] As an embodiment, the core network groups the UE1 and UE2 for paging, i.e. the core network informs the UE1 and UE2 in the Attach message that the group paging identifier is group1.

[0378] As an embodiment, the core network carries the UE group paging identifier, i.e. the Group1 group, in the paging message sent to the base station.

[0379] As an embodiment, the core network carries the information indicating that this is a group paging in the paging message sent to the base station.

[0380] As an embodiment, the base station determines that this is a group paging, and the UE1 and UE2 in the idle state will receive the paging message and inform the upper layer.

[0381] As an embodiment, if the UE1 and UE2 are in the idle state, the UE will receive the paging message and inform the upper layer.

[0382] 8. Based on 2, the terminal reports to the network whether it has the group scheduling capability:

[0383] a) Introduce the terminal capability, i.e. whether to support decoding Group PDCCH DCI; i.e. whether to support the function of group paging.

[0384] b) Introduce the terminal capability, i.e. whether to support the capability of simultaneously decoding Group PDCCH DCI and other scheduling PDCCH DCI.

[0385] c) The terminal reports to the base station through the existing UE capability information.

[0386] d) The information can be forwarded to the core network by the base station when releasing the UE.
