[0004] In practical applications, if a base station has pending services, it can send a paging message to the terminal device. Upon receiving the paging message, the terminal device enters the connected state.

[0180] The network devices involved in the embodiments of this application can be access network devices and core network devices. Taking access network devices as an example, they can include base stations and base station controllers.

[0181] The base station (BS) in this application embodiment, also referred to as base station equipment, is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in a 2G network, equipment providing base station functions includes a base transceiver station (BTS); in a 3G network, equipment providing base station functions includes a NodeB; in a 4G network, equipment providing base station functions includes an evolved NodeB (eNB); in wireless local area networks (WLANs), equipment providing base station functions is an access point (AP); in 5G new radio (NR), equipment providing base station functions includes a gNB and a next-generation eNodeB (ng-eNB).

[0183] For ease of understanding, the application scenarios applicable to the embodiments of this application will be described below with reference to Figure 1.

[0184] Figure 1 is a schematic diagram of an application scenario provided by an embodiment of this application. Referring to Figure 1, it includes a terminal device 101 and a network device 102. The terminal device 101 can be a user equipment (UE), which can be a mobile phone, tablet computer, computer, etc. The network device 102 can be a base station. Data transmission can occur between the terminal device 101 and the network device via wireless communication technology. Before data transmission, the network device 102 can initiate a paging process to the terminal device 101.

[0185] In practical applications, if a base station has pending services, it can send a paging message to a terminal device in a disconnected state. Upon receiving the paging message, the terminal device enters a connected state. However, once in the connected state, the terminal device may lack the capacity to handle the pending service, leading to service processing failure.

[0186] In this embodiment, the terminal device can receive a first message sent by the network device, the first message being used to request a first service. The terminal device then sends a response message to the network device, the response message being used to instruct the processing of the first service. In this way, the network device can initiate paging of the terminal device by sending the first message and indicate that the terminal has a first service pending processing. The terminal device can respond to the network device based on the first message to process the first service, thus enabling the network device to process a certain type of service through the terminal device.

[0187] The method described in this application will now be illustrated through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; identical or similar content will not be repeated in different embodiments.

[0188] Figure 2 is a flowchart illustrating a communication method provided in an embodiment of this application. Referring to Figure 2, the method may include:

[0189] S201, The terminal device receives the first message sent by the network device.

[0190] In other words, the network device sends the first message to the terminal device.

[0191] The terminal device can be a UE (User Equipment), which can be a mobile phone, tablet, computer, etc. The network device can be a base station. The terminal device can be in a connected state, an inactive state, or an idle state.

[0192] The first message is used to request the first service. The first service can be a sensing service, a computing service, an artificial intelligence service, etc.

[0193] The first message is downlink control information (DCI) scrambled with the Radio Network Temporary Identifier (RNTI).

[0194] The DCI format is a preset format used to indicate the first service; the RNTI value is at least one preset first RNTI value, or the RNTI value is a second RNTI value configured through the System Information Block (SIB).

[0195] The DCI includes at least one field, which is used to indicate the first service type of the first service; the first service type is indicated based on the field value of the first preset value in at least one field.

[0196] The first service type is at least one of the following: perception type, computing type, or artificial intelligence type.

[0197] For example, the preset format can be a newly defined format.

[0198] For example, the number of at least one field is N, where N is the total number of first service types configured in the SIB. The leftmost bit of at least one field indicates the first configured first service type, the second bit indicates the second configured first service type, and so on. A first preset value can be 1; when the value of a field is 1, it indicates the service type indicated by the network request field.

[0199] For example, at least one first service type configured in the SIB includes computing, perception, and artificial intelligence. Then, at least one field in the DCI includes 3 bits, where the first (leftmost) bit indicates the first service type as computing, the second (middle) bit indicates the first service type as perception, and the third (rightmost) bit indicates the first service type as artificial intelligence. Therefore, determining the requested service type includes the following three cases:

[0200] Case 1: If the field indicating the first service type in the preset format is 100, then it can be determined that the first service type requested by the network device is the computing type.

[0201] Scenario 2: If the field indicating the first service type in the preset format is 010, then it can be determined that the first service type requested by the network device is the awareness type.

[0202] Scenario 3: If the field indicating the first service type in the preset format is 001, then it can be determined that the first service type requested by the network device is the artificial intelligence type.

[0203] Each RNTI value corresponds to a first service type.

[0204] At least one of the preset first RNTI values ​​can be newly defined default values.

[0205] For example, SP-RNTI (Service Paging RNTI) can be defined as the default value, as shown in Table 1:

[0206] Table 1

[0207] For example, the first message can be DCI 1 scrambled with RNTI 1. DCI 1 is formatted as a preset format A1, which is a newly defined format. Format A1 indicates that the first service type is artificial intelligence. The value of RNTI 1 is a preset first RNTI value a1, which is a newly defined default value.

[0208] For example, the first message can be DCI 1 scrambled with RNTI 2. DCI 1 is formatted as a preset format A1, which is a newly defined format. Format A1 indicates that the first service type is artificial intelligence. The value of RNTI 2 is a second RNTI value a2 configured via SIB, and a2 corresponds to the first service type artificial intelligence.

[0209] After determining at least one RNTI value, the network device can configure at least one RNTI value in the SIB and broadcast the SIB to the terminal device. The terminal device receives the SIB, which includes at least one RNTI value, and the at least one RNTI value includes a second RNTI value.

[0210] For example, after receiving at least one RNTI value, the terminal device stores at least one RNTI value in a preset storage space of the terminal device.

[0211] For example, the network device determines that the RNTI value is 1. The network device configures a second RNTI value of 1 in the SIB and broadcasts the SIB to terminal device A1, which includes the RNTI value 1. Terminal device A1 receives the SIB, which includes the RNTI value 1. Terminal device A1 stores the RNTI value 1 in the terminal device's preset storage space.

[0212] For example, the network device determines at least one RNTI value corresponding to terminal device A2, and the first service type corresponding to each RNTI value, as shown in Table 2:

[0213] Table 2

[0214] The network device configures at least one second RNTI value as shown in Table 2 in the SIB and broadcasts the SIB to terminal device A2. The SIB includes at least one second RNTI value. Terminal device A2 receives the SIB, which includes at least one second RNTI value as shown in Table 2. Terminal device A2 stores the at least one second RNTI value as shown in Table 2 in a preset storage space of the terminal device.

[0215] The first message sent by the network device can be received in the following way: DCI is received during the first paging event.

[0216] For example, the first paging timing may be an existing paging timing or a preset paging timing. The preset paging timing may be a newly defined paging timing. The first paging timing may be a paging timing configured via SIB, or a paging timing configured in other ways; this application does not impose any restrictions.

[0217] The first message sent by the network device can be received in the following way: DCI is received through the first physical downlink control channel (PDCCH).

[0218] For example, the first PDCCH can be an existing PDCCH, or it can be a preset PDCCH. The preset PDCCH can be a newly defined PDCCH. The first PDCCH can be a PDCCH configured through SIB, or a PDCCH configured in other ways; this application does not impose any restrictions.

[0219] For example, the first paging time and the first PDCCH can be stored in a preset storage space of the terminal device.

[0220] For example, the terminal device receives the first message via PDCCH A1 at paging time A1. Here, paging time A1 is a preset paging time, and PDCCH A1 is a preset PDCCH.

[0221] For example, the terminal device receives the first message via PDCCH A2 during paging event A1. Here, paging event A1 is a preset paging event, and PDCCH A2 is an existing PDCCH.

[0222] For example, the terminal device receives the first message via PDCCH A1 during paging time A2. Here, paging time A2 is an existing paging time, and PDCCH A1 is a preset PDCCH.

[0223] For example, the terminal device receives the first message via PDCCH A2 during paging event A2. Here, paging event A2 is an existing paging event, and PDCCH A2 is an existing PDCCH.

[0224] The first message is the downlink control information (DCI) scrambled by RNTI.

[0225] The DCI includes control information and at least one field, which indicates the first service type of the first service; the first service type is indicated based on the field value of the first preset value in at least one field.

[0226] For example, the DCI format can be an existing format in which control information is included. Preset fields can be newly defined fields.

[0227] For example, the number of at least one field in the DCI is N, meaning at least one field occupies N bits, where N is the total number of first service types configured in the SIB. The most significant (leftmost) bit indicates the first configured first service type, the second bit indicates the second configured first service type, and so on. The first preset value can be 1; when the value corresponding to a field is 1, it indicates that the network requests the first service type indicated by that field.

[0228] For example, at least one first service type configured in the SIB includes computing, perception, and artificial intelligence. Then, at least one field in the DCI indicating the first service type comprises 3 bits, where the first (leftmost) bit indicates the computing type, the second (middle) bit indicates the perception type, and the third (rightmost) bit indicates the artificial intelligence type. Therefore, determining the requested service type includes the following three cases:

[0229] Case 1: If the field indicating the first service type in the preset fields is 100, then it can be determined that the first service type requested by the network device is the computing type.

[0230] Scenario 2: If the field indicating the first service type in the preset fields is 010, then it can be determined that the first service type requested by the network device is the awareness type.

[0231] Case 3: If the field indicating the first service type in the preset fields is 001, then it can be determined that the first service type requested by the network device is the artificial intelligence type.

[0232] For example, if the RNTI value is single, the first service type needs to be determined using the field in the DCI that indicates the first service type. If the RNTI value is multiple, the first service type can be determined based on the RNTI value, and whether to request the first service can be determined using the field in the DCI that indicates whether the first service is requested.

[0233] For example, the first message can be DCI1_0 scrambled with P-RNTI. Here, P-RNTI is an existing RNTI value, and DCI1_0 has an existing format. DCI1_0 includes control information and a field 010 indicating the first service type. Based on the field 010 indicating the first service type, it can be determined that the first service type requested by the network device is a sensing type.

[0234] For example, the first message can be DCI1_0 scrambled with P-RNTI. Here, P-RNTI is an existing RNTI value, and DCI1_0 has an existing format. DCI1_0 includes control information and a field indicating whether to request the first service. If the value of the field indicating whether to request the first service is 1, the terminal device can determine that the network is requesting the first service.

[0235] For example, the first message can be DCI 3 scrambled with RNTI 3. The value of RNTI 3 is a preset first RNTI value a3. Assuming the preset first RNTI value is a3, the first service type needs to be determined through the field 010 in DCI 3 that indicates the first service type. Based on the example above, it can be determined that the first service type requested by the network device is the awareness type.

[0236] For example, the first message can be DCI 3 scrambled with RNTI 3. The value of RNTI 3 is a preset first RNTI value a3. Assuming the preset first RNTI values ​​include a1, a2, and a3, the first service type can be determined to be an awareness type through the first service type corresponding to the first RNTI value a3. Then, the field in DCI 3 indicating whether a paging request is being made can be used to determine whether the service is being requested. Since the field indicating whether a paging request is being made has a value of 1, it can be determined that the network device is requesting a service of the awareness type.

[0237] The first message is a paging message, which includes at least one field indicating the first service type of the first service; the first service type is indicated based on the field value of the at least one field being a first preset value.

[0238] For example, the preset fields include at least a field indicating the first service type.

[0239] The execution process of the field indicating the first service type is the same as that shown in the above embodiment, and will not be repeated here.

[0240] For example, the first message could be DCI1_0 scrambled with P-RNTI. Here, P-RNTI is an existing RNTI value, and DCI1_0 has an existing format. After receiving DCI1_0, if the requested first service or first service type cannot be determined, the terminal device can continue to receive paging messages. These paging messages include preset fields, including a word 100 indicating the first service type. Based on the field 100 indicating the first service type, it can be determined that the first service type requested by the network device is a computing type.

[0241] S202, The terminal device sends a response message to the network device.

[0242] In other words, the network device receives the response message sent by the terminal device.

[0243] The response message is used to instruct the processing of the first service.

[0244] A response message can be sent to a network device in the following way: based on the status of the terminal device, a response message is sent to the network device.

[0245] The terminal device is in an idle state; the response message is any one of the following: a first process message, which instructs the terminal device to trigger a service request process to establish an RRC connection; a second process message, which instructs the terminal device to request to initiate an RRC connection establishment process that only restores the air interface; a preset reference signal; or a preset preamble.

[0246] For example, the idle state can be the RRC_IDLE state.

[0247] For example, when a terminal device triggers a service request process to establish an RRC connection, the first process message can be a msg5 message. The msg5 message includes the reason for establishing the connection as a response to the first message.

[0248] For example, when a terminal device requests to initiate an RRC connection that only restores the air interface, the network device, after receiving the message sent by the terminal device, may not send a message to the core network. This saves network resources.

[0249] For example, a preset reference signal and a preset preamble are used to indicate that the terminal device does not enter the connected state and receives the first message sent by the network device.

[0250] The terminal device is in an inactive state; the response message is any one of the following: a first process message, which instructs the terminal device to trigger a service request process and establish a Radio Resource Control (RRC) connection; a preset reference signal; or a preset preamble.

[0251] For example, the inactive state can be the RRC_INACTIVE state.

[0252] For example, when a terminal device triggers a service request process to establish an RRC connection, the first process message can be a msg5 message. The msg5 message includes the reason for establishing the connection as a response to the first message.

[0253] For example, a preset reference signal and a preset preamble are used to indicate that the terminal device does not enter the connected state and receives the first message sent by the network device.

[0254] The terminal device is in a connected state; the response message is any one of the following: a preset RRC message; or a preset Media Access Control Element (MAC) CE message.

[0255] For example, the connection state can be the RRC_CONNECTED state.

[0256] For example, the default RRC message is a newly defined RRC message. The default RRC message is used to indicate that the terminal device has received the first message sent by the network device.

[0257] For example, the default MAC CE message is a newly defined MAC CE message. The default MAC CE message is used to indicate that the terminal device has received the first message sent by the network device.

[0258] The communication method provided in this application embodiment involves a terminal device receiving a first message sent by a network device. The terminal device then sends a response message to the network device. In this way, the network device can initiate paging of the terminal device and indicate that the terminal has a first service pending processing by sending the first message. The terminal device can enter a connected state based on the first message and process the first service. This enables the network device to process a certain type of service through the terminal device. Furthermore, the network device can initiate paging of terminal devices in connected, idle, or inactive states, improving the flexibility of the network device in sending paging messages.

[0259] When a network device sends a first message, it can determine whether to send the first message to the terminal device based on the second service type supported by the terminal device. And / or when the terminal device receives the first message, it determines whether to respond to the first message based on the second service type supported by the terminal device. Based on any of the above embodiments, the process of communication according to the second service type will be described below with reference to Figure 3.

[0260] Figure 3 is a flowchart illustrating another communication method provided in an embodiment of this application. Referring to Figure 3, the method includes:

[0261] S301. Terminal equipment determines service capability information.

[0262] Service capability information is used to indicate a second service type supported by the terminal device. The second service type is at least one of sensing, computing, or artificial intelligence.

[0263] For example, a terminal device can determine service capability information based on computing resources, configuration information, and other information within the terminal device.

[0264] For example, if the computing resources in terminal device B1 can handle services corresponding to the artificial intelligence type, then the service capability information of terminal device B1 can be used to indicate that the second service type supported by the terminal device is the artificial intelligence type.

[0265] S302. The terminal device sends service capability information to the network device.

[0266] In other words, network devices receive service capability information sent by terminal devices.

[0267] After receiving the service capability information sent by the terminal device, the network device stores the terminal device's identifier and service capability information in a preset storage space.

[0268] S303, The terminal device receives the first message sent by the network device.

[0269] In other words, the network device sends the first message to the terminal device.

[0270] Optionally, before sending the first message, the network device can retrieve the service capability information of the terminal device from a preset storage space. If the service capability information of the terminal device matches the requested first service, the network device sends the first message to the terminal device. If the service capability information of the terminal device does not match the requested first service, the network device does not send the first message to the terminal device. This saves network resources and avoids sending invalid data to the terminal device.

[0271] The service capability information of the terminal device can be determined to match the requested first service in the following way: determine the second service type supported by the terminal device as indicated by the service capability information; if there is a second service type supported by the terminal device that matches the first service type of the first service, then it is determined that the service capability information of the terminal device matches the requested first service; if there is no second service type supported by the terminal device that matches the first service type of the first service, then it is determined that the service capability information of the terminal device does not match the requested first service.

[0272] For example, as illustrated above, the service capability information of terminal device B1 is used to indicate that the second service type supported by the terminal device is artificial intelligence. Assuming the network device needs to request service 1, before sending a first message to terminal device B1, the network device obtains the service capability information of terminal device B1. Based on the service capability information of terminal device B1, it is determined that the second service type supported by terminal device B1 is artificial intelligence. The network device determines that the first service type of service 1 matches the second service type supported by terminal device B1. Therefore, the network device sends a first message to terminal device B1, which requests service 1.

[0273] It should be noted that the process of the terminal device receiving the first message in S303 can be found in S201, and will not be repeated here.

[0274] S304. The terminal device sends a response message to the network device.

[0275] In other words, the network device receives the response message sent by the terminal device.

[0276] Optionally, after receiving the first message, the terminal device determines whether the second service type supported by the terminal device matches the first service in the first message. If yes, it sends a response message to the network device. If no, it discards the first message and does not respond to it.

[0277] It should be noted that the process of determining whether the second service type supported by the terminal device matches the first service type of the first service in the first message can be found in S303, which describes the process of determining whether the service capability information of the terminal device matches the requested first service. This will not be repeated here.

[0278] For example, terminal device B2 receives a first message from a network device requesting service 1, where the first service type of service 1 is artificial intelligence. Terminal device B2's service capability information indicates that it supports second service types including computing and artificial intelligence. Terminal device B2 determines that the second service type it supports matches the first service type in the first message. At this point, terminal device B2 sends a response message to the network device.

[0279] Optionally, after receiving the first message, the terminal device determines, based on the first message, that the second service type supported by the terminal device matches the first service type in the first message, and that the terminal device's current idle computing resources can handle the first service, and then sends a response message to the network device. If the second service type supported by the terminal device does not match the first service type in the first message, or if the terminal device's current idle computing resources cannot handle the first service, then the first message is discarded, and no response is given to the first message.

[0280] For example, terminal device B2 receives a first message from a network device requesting service 1, where the first service type of service 1 is artificial intelligence. Terminal device B2's service capability information indicates that it supports second service types, including computing and artificial intelligence. Terminal device B2 determines that the second service type it supports matches the first service type in the first message. If terminal device B2 determines that its current idle computing resources can handle service 1, it sends a response message to the network device.

[0281] It should be noted that the execution process of the terminal device sending the response message in S303 can be found in S202, and will not be repeated here.

[0282] The communication method provided in this application embodiment involves a terminal device determining service capability information and sending the service capability information to a network device. The terminal device receives a first message sent by the network device. The terminal device then sends a response message to the network device. During this process, the terminal device can determine whether to send a response message to the network device based on the service capability information. The network device can also determine whether to send a first message to the terminal device based on the service capability information. This avoids situations where the network device requests a service corresponding to an unsupported first service type from the terminal device, or where the terminal device, even when not supporting the first service type, still needs to send a response message indicating that it does not support the service corresponding to the first service type upon receiving the first message. This saves network resources and improves communication efficiency.

[0283] If, after receiving the first message from the network device, the terminal device cannot determine whether to request service based on the first message, it can also receive the second message from the network device and respond accordingly. Based on any of the above embodiments, the process of the terminal device responding to a paging message will be described below with reference to Figure 4.

[0284] Figure 4 is a flowchart illustrating another communication method provided in an embodiment of this application. Referring to Figure 4, the method includes:

[0285] S401, The terminal device receives the first message sent by the network device.

[0286] In other words, the network device sends the first message to the terminal device.

[0287] S402, The terminal device receives the second message sent by the network device.

[0288] In other words, the network device sends a second message to the terminal device.

[0289] After receiving the first message from the network device, if the terminal device cannot determine whether to request a service based on the first message, it receives a second message from the network device. The second message is used to request the first service. The second message is a DCI (Distributed Content Message), which includes fields indicating that the first service is requested.

[0290] For example, if the first message does not include a field indicating the first service type, or if the first message does not indicate a request for the first service, then the terminal device cannot determine whether to request the first service based on the first message. In this case, it can receive the second message sent by the network device before receiving the paging message.

[0291] For example, the field occupies 1 bit. If the field value corresponding to the field is a first preset value, then the field can be determined to indicate a service request. In this case, the terminal device determines the first service type of the network service request by receiving a paging message.

[0292] For example, after terminal device B3 receives a second message from the network device, the second message includes a field whose value is 1. This indicates a request for the first service.

[0293] S403. The terminal device receives a paging message sent by the network device.

[0294] In other words, network devices receive paging messages sent by terminal devices.

[0295] The paging message includes at least one field, which is used to indicate the first service type of the first service; the first service type is indicated based on the field value of the at least one field being a first preset value.

[0296] The execution process of the field indicating the first service type is the same as that shown in the above embodiment, and will not be repeated here.

[0297] For example, a terminal device can receive paging messages through the Physical Downlink Shared Channel (PDSCH).

[0298] For example, after receiving the second message as illustrated above, terminal device B3 determines that a field in the second message indicates a request for the first service. At this time, terminal device B3 receives a paging message via PDSCH. The paging message contains field B1, which indicates that the first service type is artificial intelligence. Terminal device B3 can then respond according to the paging message.

[0299] S404, The terminal device sends a response message to the network device.

[0300] In other words, the network device receives the response message sent by the terminal device.

[0301] It should be noted that the execution process of S403 can be found in S202, and will not be repeated here.

[0302] The communication method provided in this application embodiment allows the terminal device to continue receiving paging messages even when it cannot determine the relevant information of the first service after receiving the first message. Based on the fields in the paging message, the first service type of the first service is determined, and a response is then initiated. This avoids situations where the terminal device cannot respond when the first message is abnormal, thus improving communication efficiency.

[0303] Network devices can also receive messages sent by other network devices, enabling those devices to request the first service. Based on any of the above embodiments, the process of the core network requesting the first service will be described below with reference to Figure 5.

[0304] Figure 5 is a flowchart illustrating another communication method provided in an embodiment of this application. Referring to Figure 5, the method includes:

[0305] S501, The first network device receives the first message sent by the second network device.

[0306] In other words, the second network device sends the first message to the first network device.

[0307] The first and second network devices are base stations.

[0308] The first network device receives a request message through a first interface, which indicates a request for a first service. The first interface is the Xn interface.

[0309] The request message is a paging message, which includes at least one field indicating the first service type of the first service; or, the request message is a preset paging message.

[0310] The first service type is indicated by a field whose value is a first preset value in at least one field.

[0311] An example paging message could be a Radio Access Network Paging (RAN Paging) message.

[0312] For example, the preset paging message can be a newly defined paging message.

[0313] For example, network device A receives a first message sent by network device B through the Xn interface. This first message is a paging message. The paging message includes a field A1, which indicates that the first service type is a perception type.

[0314] S502, The first network device sends a response message to the second network device.

[0315] In other words, the second network device receives the response message sent by the first network device.

[0316] After receiving the first message, the first network device can process it and respond independently. Alternatively, it can send the first message to other network devices for a response. It can also send the first message to a terminal device for a response.

[0317] For example, as illustrated above, after receiving the first message, network device A can send a response message to network device B based on the first message. Alternatively, it can send the first message to network device C, which then sends a response message to network device A. Or, it can send the first message to terminal device B3, which then sends a response message to network device A based on the first message. Network device A then sends a response message to network device B.

[0318] It should be noted that the execution process of the first message and the response message in S501 to S502 can be referred to any of the above embodiments, and will not be repeated here.

[0319] The communication method provided in this application allows base stations to initiate paging to request a first service. It is not limited to paging between base stations and terminal devices, thus improving communication flexibility.

[0320] Network devices can also receive messages sent by the core network to request the first service. Based on any of the above embodiments, the process of the core network requesting the first service will be described below with reference to Figure 6.

[0321] Figure 6 is a flowchart illustrating another communication method provided in an embodiment of this application. Referring to Figure 6, the method includes:

[0322] S601, The network device receives the first message sent by the core network.

[0323] In other words, the core network sends the first message to the network devices.

[0324] The first network device receives a request message through the first interface, which indicates a request for the first service. The first interface is an NG interface.

[0325] For example, the NG interface can be an existing NG interface or a preset NG interface. The preset NG interface can be a newly defined NG interface.

[0326] The request message is a paging message, which includes at least one field indicating the first service type of the first service; or, the request message is a preset paging message.

[0327] The first service type is indicated by a field whose value is a first preset value in at least one field.

[0328] For example, the preset paging message can be a newly defined paging message.

[0329] For example, network device A receives a first message sent by the core network through the NG interface. This first message is a paging message. The paging message includes a field A1, which indicates that the first service type of the first service is the awareness type.

[0330] S602, The network device sends a response message to the core network.

[0331] In other words, the core network receives response messages sent by network devices.

[0332] After receiving the first message, the first network device can process it and respond independently. Alternatively, it can send the first message to other network devices for a response. It can also send the first message to a terminal device for a response.

[0333] For example, as illustrated above, after receiving the first message, network device A can send a response message to the core network based on the first message. Alternatively, it can send the first message to network device B, which then sends a response message to the core network. Or, it can send the first message to terminal device B3, which then sends a response message to network device A based on the first message. Network device A then sends a response message to the core network.

[0334] It should be noted that the execution process of the first message and the response message in S601 to S602 can be referred to any of the above embodiments, and will not be repeated here.

[0335] The communication method provided in this application embodiment allows the core network to initiate a paging request to a base station, thereby requesting a first service. The base station can obtain responses from other base stations through terminal devices, and is not limited to the communication process of requesting a first service between a base station and a terminal device, thus improving communication flexibility.

[0336] The core network can also receive messages from other core networks requesting the first service. Based on any of the above embodiments, the process of core networks requesting the first service will be described below with reference to Figure 7.

[0337] Figure 7 is a flowchart illustrating another communication method provided in an embodiment of this application. Referring to Figure 7, the method includes:

[0338] S701, the first core network receives the first message sent by the second core network.

[0339] In other words, the second core network sends the first message to the first core network.

[0340] The first core network receives request messages through the first interface, which indicates a request for the first service. The first interface is the NG interface.

[0341] For example, the NG interface can be an existing NG interface or a preset NG interface. The preset NG interface can be a newly defined NG interface.

[0342] The request message is a paging message, which includes at least one field indicating the first service type of the first service; or, the request message is a preset paging message.

[0343] The first service type is indicated by a field whose value is a first preset value in at least one field.

[0344] For example, the preset paging message can be a newly defined paging message.

[0345] For example, core network A receives a first message from core network B via the NG interface. This first message is a paging message. The paging message includes field A1, which indicates that the first service type of the first service is the awareness type.

[0346] S502, the first core network sends a response message to the second core network.

[0347] In other words, the second core network receives the response messages sent by the first core network.

[0348] After receiving the first message, the primary core network can process and respond independently. Alternatively, it can send the first message to other core networks for responses. It can also send the first message to network devices for responses.

[0349] For example, as illustrated above, after receiving the first message, core network A can send a response message to core network B based on the first message. Alternatively, it can send the first message to core network C, which then sends a response message to core network A. Or, it can send the first message to network device A, which then sends a response message.

[0350] It should be noted that the execution process of the first message and the response message in S701 to S702 can be referred to any of the above embodiments, and will not be repeated here.

[0351] The communication method provided in this application allows core networks to initiate paging to request a first service. It is not limited to paging between base stations and terminal devices, thus improving communication flexibility.

[0352] Figure 8 is a schematic diagram of a communication device provided in an embodiment of this application. The communication device 10 can be a terminal device, or a chip or chip module in a terminal device. Referring to Figure 8, the communication device 10 may include:

[0353] The first receiving module 11 is used to receive a first message sent by the network device, the first message being used to request a first service;

[0354] The sending module 12 is used to send a response message to the network device, the response message being used to instruct the processing of the first service.

[0355] In one possible implementation, the first message is downlink control information (DCI) scrambled with a Radio Network Temporary Identifier (RNTI).

[0356] In one possible implementation, the DCI is in a preset format, which is used to indicate the first service;

[0357] The value of the RNTI is at least one preset first RNTI value, or the value of the RNTI is a second RNTI value configured through the System Information Block (SIB).

[0358] In one possible implementation, the DCI includes at least one field indicating a first service type of the first service;

[0359] The first service type is indicated by a field whose value is a first preset value in at least one of the fields.
