[0116] In some scenarios, such as when the terminal is placed in a pocket or backpack, in a vehicle, or blocked by objects such as buildings and leaves, the terminal's path loss will increase significantly, causing the signal-to-noise ratio (SNR) at the receiving end to drop sharply. As a result, when the terminal has a called service, the terminal cannot perceive its own channel status in real time, resulting in failure to receive key paging messages, missed calls and messages, and seriously affecting the effectiveness and reliability of communications.

[0129] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0130] It can be understood that in the embodiments of the present application, "used for indication" can include direct indication and indirect indication, and can also include explicit indication and implicit indication. The information indicated by a certain information is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, where there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, it is also possible to use a pre-agreed (such as a protocol provision) on whether a certain information element exists to implement the indication of the information to be indicated, thereby reducing the indication overhead to a certain extent.

[0131] It is understood that in the embodiments shown below, the first, second, and various numerical numbers are merely distinctions for ease of description and are not intended to limit the scope of the embodiments of the present application, for example, to distinguish different indication information, different time intervals, and the like.

[0132] It is understandable that the "preset value" can be implemented by pre-saving the corresponding code, table or other methods that can be used to indicate relevant information in the device (for example, including the terminal, access network element and core network element), and this application does not limit its specific implementation method. Among them, "saving" can mean saving in one or more memories. One or more memories can be set separately or integrated in an encoder or decoder, a processor, or a communication device. One or more memories can also be partially set separately and partially integrated in a decoder, a processor, or a communication device.

This application does not limit this.

[0134] It is understandable that "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c. Where a, b and c can be single or plural, respectively.

[0135] It can be understood that in the embodiments of the present application, descriptions such as "when...", "in the case of...", "if" and "if" all mean that the device (such as a terminal device or a network device) will make corresponding processing under certain objective circumstances.

[0141] Figure 2 FIG. 1 is a flow chart of a communication method according to an embodiment of the present application; Figure 2 As shown, it may include steps S201 to S202. Figure 2 Each step in .

[0142] S201. The core network element sends first elastic notification indication information to the access network element.

[0143] In some embodiments, the terminal is in an idle state. When the terminal has a called service, such as answering a call, receiving a firmware upgrade program, etc., the terminal will receive a paging message from the access network element. Before the terminal receives the paging message from the access network element, the core network will send a first elastic notification indication information to the access network element.

[0144] In some embodiments, the core network element determines that the terminal has a called service, and sends first elastic notification indication information to the access network element.

[0145] In some embodiments, the first elastic notification indication information is used to instruct the access network element to send an elastic notification message.

[0146] In some embodiments, the core network element is an AMF network element.

[0147] In some embodiments, the AMF network element sets the first elastic notification indication information and sends the first elastic notification indication information to the access network element.

[0148] In some embodiments, the core network element includes a session management function (SMF) network element and an AMF network element. The SMF network element sets a first elastic notification indication information and sends the first elastic notification indication information to the AMF network element. The AMF network element sends the first elastic notification indication information to the access network element.

[0149] S202: The access network element sends a flexible notification message to the terminal.

[0150] In some embodiments, the access network element receives the first elastic notification indication information, and sends an elastic notification message to the terminal according to the first elastic notification indication information.

[0151] The flexible notification message can notify the terminal of the existence of the first paging message, thereby preventing the terminal from missing the first paging message and improving the delivery success rate of the paging message of the terminal.

[0152] In some embodiments, the terminal has a called service, and the terminal receives a first paging message from an access network element, and the flexible notification message is a flexible notification of the first paging message.

[0153] In some embodiments, the first paging message and the flexible notification message may be sent to the terminal within the same preset paging cycle.

[0154] In some embodiments, the access network element may first send a first paging message. When the timer of the first paging message expires and the access network element does not receive a second response message from the terminal to the first paging message, the access network element sends a flexible notification message to the terminal.

[0155] In some embodiments, the first elastic notification indication information includes a first field, and the access network element sends the elastic notification message according to a value corresponding to the first field.

[0156] For example, in some embodiments, based on the value of the first field, it is determined that the first paging message and the elastic notification message are sent to the terminal within the same preset paging cycle, or it is determined that the first paging message is sent first, and when the timer of the first paging message expires and the access network element does not receive the second response message from the terminal to the first paging message, the elastic notification message is sent to the terminal.

[0157] In an embodiment of the present application, when the terminal has a called service, the core network element instructs the access network to send an elastic notification message to the terminal through the first elastic notification indication information, so as to prevent the terminal from missing the paging message, increase the probability of the terminal receiving the elastic notification message, increase the success rate of the paging message transmission, and improve the communication instructions and experience of the terminal.

[0158] Figure 3 FIG. 1 is a flow chart of a communication method shown in another embodiment of the present application; Figure 3 As shown, it may include steps S301 to S303. Figure 3 Each step in .

[0159] S301. A core network element sends first elastic notification indication information to an access network element.

[0160] In some embodiments, the terminal has a called service, and the core network element sends first elastic notification indication information to the access network element.

[0161] In one embodiment, the core network element includes a user plane function (UPF) network element. The UPF network element receives called data and determines that a called service exists on the terminal.

[0162] In some embodiments, the first elastic notification indication information is used to instruct the access network element to send an elastic notification message.

[0163] In some embodiments, the first flexible notification indication information includes a first field, and the first field has a corresponding value.

[0164] In some embodiments, the first field may be used to instruct the access network element to send a resiliency notification message, and in this case, the first field has a corresponding value.

[0165] In some embodiments, the first field can be used to indicate whether the access network element sends an elastic notification message. When the first field has some values, it can be used to indicate that the access network element sends an elastic notification message; when the first field has other values, it can be used to indicate that the access network element does not send an elastic notification message.

[0166] For example, in some embodiments, when the first field value is one of the first preset value, the second preset value, or the third preset value, it is used to instruct the access network element to send a flexible notification message.

[0167] When the first field value is the fourth preset value, it is used to instruct the access network element not to send the elastic notification message.

[0168] In some embodiments, when the first field has a corresponding value, it can be used to instruct the access network element to send a resilience notification message.

[0169] In some embodiments, when the first field has a corresponding value, and the first field has a corresponding value used to indicate that the access network element sends an elastic notification message, the value corresponding to the first field is different, and the way in which the access network element sends the elastic notification message is also different.

[0170] When the value of the first field is a first preset value, the access network element sends a first paging message within a preset paging cycle and sends a flexible notification message within the preset paging cycle.

[0171] When the value of the first field is the second preset value, the access network element sends a first paging message to the terminal; and when the timer of the first paging message expires and the second response message of the terminal to the first paging message is not received, the access network element sends a flexible notification message to the terminal.

[0172] When the value of the first field is the third preset value, the access network element sends a first paging message and an elastic notification message within a preset paging cycle; or, the access network element sends a first paging message to the terminal, and when the timer of the first paging message expires and the second response message of the terminal to the first paging message is not received, the access network element sends an elastic notification message to the terminal.

[0173] In this way, the different values ​​corresponding to the first field in the first elastic notification indication information indicate the manner in which the access network element sends the elastic notification message.

[0174] The first preset value, the second preset value and the third preset value are all different, and the first field can be any field name, which is not specifically limited here.

[0175] The first preset value, the second preset value and the third preset value can be characters, numbers or character strings, and are not specifically limited here.

[0176] For example, in one embodiment, the first preset value is "1", the second preset value is "2", and the third preset value is "3".

[0177] In some embodiments, the first flexible notification indication information further includes at least one of the following: caller information; service type information.

[0178] The caller information is used to indicate the information of the caller who issues the called service to the terminal. The caller information may include a whitelist caller or a common caller.

[0179] In some embodiments, the service type information is used to indicate the type of the called service of the terminal. For example, the service type information can be a voice type called service, a short message type called service, a public warning message type called service, or a data type called service, which will not be elaborated here.

[0180] In some embodiments, the first flexible notification indication information is included in a second paging message sent by the core network element.

[0181] In some embodiments, the core network element sends a second paging message to the access network element, where the second paging message is used to indicate to the access network element that there is a called service on the terminal.

[0182] The second paging message includes first flexible notification indication information.

[0183] In some embodiments, the terminal has a called service, and the core network element sends a second paging message to the access network element.

[0184] In some embodiments, the core network element determines that the terminal has a called service and sets first flexible notification indication information.

[0185] The setting of the first flexible notification indication information can be regarded as setting the value corresponding to the first field, thereby instructing the access network element how to send the flexible notification message.

[0186] In some embodiments, the core network element is an AMF network element, the AMF network element sets the first elastic notification indication information, and sends the first elastic notification indication information to the access network element.

[0187] In some embodiments, the core network element includes an SMF network element and an AMF network element. The SMF network element sets a first elastic notification indication information and sends the first elastic notification indication information to the AMF network element. The AMF network element sends the first elastic notification indication information to the access network element.

[0188] In some embodiments, the core network element sends first elastic notification indication information to the access network element based on the first elastic notification capability indication information of the terminal, the second elastic notification capability indication information of the access network element, and the third elastic notification capability indication information of the core network element.

[0189] In some embodiments, the core network element sets the first elastic notification indication information based on the first elastic notification capability indication information of the terminal, the second elastic notification capability indication information of the access network element, and the third elastic notification capability indication information of the core network element, and sends the first elastic notification indication information to the access network element.

[0190] In some embodiments, the first flexible notification capability indication information is used to indicate whether the terminal supports the flexible notification capability.

[0191] In some embodiments, the second flexible notification capability indication information is used to indicate whether the access network element supports the flexible notification capability.

[0192] In some embodiments, the third flexible notification capability indication information is used to indicate whether the core network element supports the flexible notification capability.

[0193] In some embodiments, when the first elastic notification capability indication information indicates that the terminal supports elastic notification capability, the second elastic notification capability indication information indicates that the access network element supports elastic notification capability, and the third elastic notification capability indication information indicates that the core network element supports elastic notification capability, the core network element sends the first elastic notification indication information to the access network element.

[0194] In some embodiments, before the core network element sends the first elastic notification indication information, the terminal sends the first elastic notification capability indication information to the core network element through the access network element, so that the core network element receives the first elastic notification capability indication information.

[0195] In some embodiments, the terminal sends the first elastic notification capability indication information to the access network element, and the access network element sends the first elastic notification capability indication information to the core network element.

[0196] In some embodiments, before the core network element sends the first elastic notification indication information, the access network element sends the second elastic notification capability indication information to the core network element, so that the core network element receives the second elastic notification capability indication information.

[0197] The core network element may also include one or more AMF network elements and SMF network elements. The AMF network element or SMF network element sets the first elastic notification indication information according to the first elastic notification capability indication information of the terminal, the second elastic notification capability indication information of the access network element and the third elastic notification capability indication information of the core network element and sends the first elastic notification indication information to the access network element.

[0198] In some embodiments, the access network element can also determine the elastic notification service subscription information of the terminal, thereby setting the first elastic notification indication information according to the first elastic notification capability indication information, the elastic notification service subscription message of the terminal, the second elastic notification capability indication information of the access network element, and the third elastic notification capability indication information of the core network element, and sending the first elastic notification indication information to the access network element.

[0199] In some embodiments, the elastic notification service subscription information indicates whether the terminal subscribes to the elastic notification service. Only when the elastic notification service subscription information indicates that the terminal subscribes to the elastic notification service, the first elastic notification indication information is sent to the access network element. The elastic notification service subscription information is obtained in the unified data management (UDM) network element.

[0200] In some embodiments, when the first elastic notification capability indication information indicates that the terminal supports the elastic notification capability, the second elastic notification capability indication information indicates that the access network element supports the elastic notification capability, the third elastic notification capability indication information indicates that the core network element supports the elastic notification capability, and the elastic notification service subscription information indicates that the terminal subscribes to the elastic notification service, the core network element sends the first elastic notification indication information to the access network element. In some embodiments, the first elastic notification capability indication information includes a second field, and when the value of the second field is a fifth preset value, it is used to indicate that the terminal supports the elastic notification capability; when the value of the second field is a sixth preset value, it is used to indicate that the terminal does not support the elastic notification capability.

[0201] In some embodiments, when the first flexible notification capability indication information does not include the second field, it is used to indicate that the terminal does not support the flexible notification capability.

[0202] The second field is used to indicate whether the terminal supports the flexible notification capability.

[0203] The fifth preset value is different from the sixth preset value, and the second field can be any field name, which is not specifically limited here.

[0204] For example, in one embodiment, the fifth preset value is “1” and the sixth preset value is “0”.

[0205] In some embodiments, the second elastic notification capability indication information includes a third field, which is used to indicate that the access network element supports elastic notification capability when the value of the third field is the seventh preset value; when the value of the third field is the eighth preset value, it is used to indicate that the access network element does not support elastic notification capability.

[0206] In some embodiments, when the second flexible notification capability indication information does not include the third field, it is used to indicate that the access network element does not support the flexible notification capability.

[0207] The third field is used to indicate whether the access network element supports the elastic notification capability.

[0208] The seventh preset value is different from the eighth preset value, and the third field can be any field name, which is not specifically limited here.

[0209] For example, in one embodiment, the seventh preset value is “1” and the eighth preset value is “0”.

[0210] In some embodiments, the third elastic notification capability indication information includes a fourth field, which is used to indicate that the core network element supports elastic notification capability when the value of the fourth field is a ninth preset value; and is used to indicate that the core network element does not support elastic notification capability when the value of the third field is a tenth preset value.

[0211] In some embodiments, when the third elastic notification capability indication information does not include the fourth field, it is used to indicate that the core network element does not support the elastic notification capability.

[0212] The fourth field is used to indicate whether the core network element supports the elastic notification capability.

[0213] The ninth preset value is different from the tenth preset value, and the fourth field can be any field name, which is not specifically limited here.

[0214] For example, in one embodiment, the ninth preset value is “1” and the tenth preset value is “0”.

[0215] S302: The access network element sends a first paging message to the terminal.

[0216] In some embodiments, the first field in the first flexible notification indication information is a first preset value, and the access network element sends the first paging message and the flexible notification message respectively within a preset paging cycle.

[0217] In some embodiments, the access network element sends a first paging message to the terminal within a preset paging cycle.

[0218] In some embodiments, the terminal has a called service, the network allocates a preset paging cycle to the terminal, the first paging message is sent within the preset paging cycle, and the flexible notification message is also sent within the preset paging cycle.

[0219] In some embodiments, the first paging message may be sent repeatedly until a maximum number of repetitions of the first paging message is reached or a preset paging cycle is exceeded, or the access network element receives a response from the terminal to the first paging message.

[0220] S303: The access network element sends a flexible notification message to the terminal.

[0221] In some embodiments, the first field in the first flexible notification indication information is a first preset value, and the access network element sends the first paging message and the flexible notification message respectively within a preset paging cycle.

[0222] In some embodiments, step S302 and step S303 occur within the same preset paging cycle.

[0223] In some embodiments, the execution order of step S303 and step S302 can be swapped.

[0224] In some embodiments, the elastic notification message may be sent repeatedly until the access network element receives a first response message from the terminal to the elastic notification message, or the preset paging cycle is exceeded, or the number of times the elastic notification message is sent reaches a preset first number of repetitions.

[0225] In some embodiments, by setting repeated sending of the flexible notification message, the probability of the terminal receiving the flexible notification message can be increased, thereby reducing the probability of the terminal missing the first paging message.

[0226] The number of times the flexible notification message is repeatedly sent can be set, such as being set to a preset first number of repeated sending times, that is, the maximum number of times the flexible notification message is repeatedly sent is the preset first number of repeated sending times.

[0227] In some embodiments, the access network element sends an elastic notification message within a preset paging cycle. If the access network element does not receive a first response message sent by the terminal, it repeatedly sends the elastic notification message until it receives the first response message sent by the terminal, or exceeds the preset paging cycle, or the number of times the elastic notification message is sent reaches a preset first number of repetitions.

[0228] It can be understood that the repeated sending of the flexible notification message needs to be sent within a preset paging cycle.

[0229] In some embodiments, the access network element may further set the frame in which the elastic notification message is sent and the corresponding position on the frame at which it is sent.

[0230] In some embodiments, the access network element may determine elastic notification frame parameters, elastic notification quantity, service identifier of the elastic notification message, sending timing offset, terminal identifier, and elastic notification subgroup parameters.

[0231] In some embodiments, the access network element determines the elastic notification sending position on the elastic notification frame based on the elastic notification frame parameters, the number of elastic notifications, the service identifier of the elastic notification message, the sending timing offset, the terminal identifier, and the elastic notification subgroup parameters, so as to send the elastic notification message at the elastic notification sending position on the elastic notification frame.

[0232] In some embodiments, the access network element may also broadcast the elastic notification frame parameters, the number of elastic notifications, the service identifier of the elastic notification message, the sending timing offset, and the elastic notification subgroup parameters through a system message, so that the terminal can determine the elastic notification sending position on the elastic notification frame, and thus the terminal receives the elastic notification message at the elastic notification sending position on the elastic notification frame.

[0233] In some embodiments, the elastic notification frame parameter is used to indicate the elastic notification frame in which the elastic notification message is located.

[0234] For example, in some embodiments, the elastic notification frame parameter is a frame offset from a frame for sending the first paging message, and the frame for sending the first paging message can be determined, thereby determining the elastic notification frame through the frame for sending the first paging message and the frame offset, and the elastic notification frame is a frame for sending the elastic notification message.

[0235] In some embodiments, the elastic notification number is used to indicate the maximum number of elastic notification messages that can be sent in one elastic notification frame.

[0236] In some embodiments, the service identifier of the elastic notification message is the identifier corresponding to the type of the called service of the elastic notification message sent this time, that is, the identifier of the type of the called service corresponding to the first paging message, and can also be regarded as the identifier of the type of the called service of the terminal corresponding to the service type information.

[0237] In some embodiments, the transmission timing offset is used to indicate the number of symbols offset on the flexible notification frame.

[0238] In some embodiments, the elastic notification subgroup parameter is a positive integer, which is a pre-configured value, and the value of the elastic notification subgroup parameter is smaller than the value of the elastic notification quantity.

[0239] In some embodiments, multiple groups can be set according to different positions on the elastic notification frame. If the terminal is located in one of the multiple groups, the elastic notification message of the first paging message of the terminal is sent at the position on the elastic notification frame corresponding to the group where the terminal is located, thereby reducing the possibility of terminals that are not paged (other terminals) receiving the elastic notification message to read the first paging message, avoiding other terminals from wasting unnecessary power. The terminal receives the elastic notification message at the corresponding position on the elastic notification frame of the corresponding group, thereby reading the first paging message.

[0240] In some embodiments, after determining the corresponding position of the terminal group on the elastic notification frame, the elastic notification sending position on the elastic notification frame can also be determined based on the corresponding position of the terminal group on the elastic notification frame and the sending timing offset.

[0241] In some embodiments, the access network element determines the elastic notification frame based on the elastic notification frame parameters, and the access network element determines the elastic notification sending position on the elastic notification frame based on the service identifier, elastic notification quantity, elastic notification subgroup parameters and sending timing offset of the elastic notification message, so that the access network element can send the elastic notification message at the elastic notification sending position on the elastic notification frame.

[0242] The access network element determines the corresponding position of the group to which the terminal belongs on the elastic notification frame based on the service identifier, the elastic notification quantity, and the elastic notification subgroup parameter of the elastic notification message.

[0243] In some embodiments, the corresponding position of the group to which the terminal belongs on the flexible notification frame indicates the symbol number on the flexible notification frame.

[0244] In some embodiments, the calculated corresponding position of the terminal group on the elastic notification frame is a positive integer. If the integer is n, it indicates the nth symbol on the elastic notification frame. The nth symbol on the elastic notification frame is the corresponding position of the terminal group on the elastic notification frame.

[0245] In some embodiments, the corresponding position y of the group to which the terminal belongs on the elastic notification frame may be calculated as follows:

[0246] y=((floor(UE_ID) / ((N-1) Ns)) mod A) + (floor(RS_ID) mod A)

[0247] Among them, floor is rounded down, UE_ID is the terminal identifier, which can be sent by the core network element to the access network element, N is the number of paging message frames that can be sent within the preset paging cycle, Ns is the value of the elastic notification quantity, mod is the remainder, A is the value of the elastic notification subgroup parameter, and RS_ID is the service identifier of the elastic notification message.

[0248] In some embodiments, after obtaining the corresponding position of the terminal group on the elastic notification frame, it is determined whether the corresponding position of the terminal group on the elastic notification frame is before the preset position on the elastic notification frame. If it is before the preset position on the elastic notification frame, the sending timing offset is shifted backward at the corresponding position of the terminal group on the elastic notification frame to obtain the elastic notification sending position.

[0249] In some embodiments, the corresponding position of the terminal group on the elastic notification frame is used to indicate the nth symbol on the elastic notification frame, and the sending timing offset is used to indicate the number of offset symbols. For example, in one embodiment, the sending time offset is m, and the corresponding position of the terminal group on the elastic notification frame is before the preset position on the elastic notification frame, then the elastic notification sending position is the n+mth symbol on the elastic notification frame.

[0250] In some embodiments, the preset position on the elastic notification frame is also used to indicate the position of the symbol on the elastic notification frame. For example, the preset position of the elastic notification is the xth symbol on the elastic notification frame. The x can be set in advance, and the x is a positive integer. The x can be sent to the terminal via a system message, or the preset position of the elastic notification can be regarded as being sent to the terminal via a system message.

[0251] In some embodiments, if the corresponding position of the terminal group on the elastic notification frame is located after the preset position on the elastic notification frame, or the corresponding position of the terminal group on the elastic notification frame is the same as the preset position on the elastic notification frame, then the corresponding position of the terminal group on the elastic notification frame is the elastic notification sending position.

[0252] By using the sending timing offset, it is possible to avoid the elastic notification message being sent near the frame header of the elastic notification frame, thereby improving the reliability of the elastic notification message sending.

[0253] In other embodiments, after obtaining the corresponding position of the terminal group on the elastic notification frame, it is also possible not to determine whether the corresponding position of the terminal group on the elastic notification frame is before the preset position on the elastic notification frame, but directly shift the sending timing offset backward from the corresponding position of the terminal group on the elastic notification frame to obtain the elastic notification sending position.

[0254] In some embodiments, when a terminal receives a system message, it may also determine an elastic notification frame based on the elastic notification frame parameters; determine the elastic notification sending position on the elastic notification frame based on the service identifier, elastic notification quantity, elastic notification subgroup parameters and sending timing offset of the elastic notification message; and receive the elastic notification message at the elastic notification sending position on the elastic notification frame.

[0255] The manner in which the terminal determines the location for sending the elastic notification may refer to the manner in which the access network element determines the location for sending the elastic notification, which will not be described in detail here.

[0256] In some embodiments, step S301 and step S303 are replaceable, such as step S301 can be replaced by the core network element sending a second elastic notification indication message to the access network element. When step S301 can be replaced by the core network element sending a second elastic notification indication message to the access network element, step S302 is executed, but step S303 is not executed.

[0257] In some embodiments, the second flexible notification indication information is used to indicate not to send a flexible notification message.

[0258] In some embodiments, the second flexible notification indication information does not include the first field.

[0259] When the second elastic notification indication information does not include the first field, it is used to instruct the access network element not to send an elastic notification message to the terminal.

[0260] In some embodiments, the second flexible notification indication information includes a first field, and a value of the first field is a fourth preset value.

[0261] When the value of the first field is the fourth preset value, it is used to indicate that the elastic notification message is not sent, that is, the access network element does not send the elastic notification message to the terminal.

[0262] In some embodiments, the fourth preset value is different from the third preset value, the second preset value, and the first preset value.

[0263] The fourth preset value can be a character, a numerical value, a string, etc., and is not specifically limited here.

[0264] In one embodiment, the fourth preset value is “0”.

[0265] In some embodiments, the second flexible notification indication information is included in a second paging message sent by the core network element.

[0266] In some embodiments, the core network element sends a second paging message to the access network element, where the second paging message includes second elastic notification indication information.

[0267] In some embodiments, the terminal has a called service, and the core network element sends a second elastic notification indication information to the access network element based on the first elastic notification capability indication information of the terminal, the second elastic notification capability indication information of the access network element, and the third elastic notification capability indication information of the core network element.

[0268] In some embodiments, the core network element sends a second elastic notification indication message to the access network element when any of the following situations exists: the first elastic notification capability indication message indicates that the terminal does not support elastic notification capability, the second elastic notification capability indication message indicates that the access network element supports elastic notification capability, or the third elastic notification capability indication message indicates that the core network element supports elastic notification capability.

[0269] In some embodiments, if any one of the terminal, the core network element, and the access network element does not support the elastic notification capability, the core network element sends the second elastic notification indication information to the access network element.

[0270] In some embodiments, the core network element may also send second elastic notification indication information to the access network element based on the first elastic notification capability indication information, the second elastic notification capability indication information of the access network element, the elastic notification service subscription information and the third elastic notification capability indication information of the core network element.

[0271] In some embodiments, the core network element sends second elastic notification indication information to the access network element when any of the following situations exists: the first elastic notification capability indication information indicates that the terminal does not support the elastic notification capability, the second elastic notification capability indication information indicates that the access network element supports the elastic notification capability, the third elastic notification capability indication information indicates that the core network element supports the elastic notification capability, or the elastic notification service subscription information indicates that the terminal has not subscribed to the elastic notification service. In this embodiment of the present application, when the terminal has a called service, the core network element instructs the access network element to send an elastic notification message to the terminal through the first elastic notification capability indication information to improve the success rate of the terminal paging message, improve the communication quality, and avoid missing the terminal paging message.

[0272] at the same time, Figure 3 It is shown in FIG. 5 that when the first field is a first preset value, the access network element may send a first paging message and a flexible notification message within a preset paging cycle.

[0273] Figure 4 FIG. 1 is a flow chart of a communication method shown in another embodiment of the present application; Figure 4 As shown, it may include steps S401 to S403. Figure 4 Each step in .

[0274] S401. The core network element sends first elastic notification indication information to the access network element.

[0275] It can be understood that the implementation method of the core network element sending the first elastic notification indication information to the access network element can refer to step S301, which is not described here in detail.

[0276] S402: The access network element sends a first paging message to the terminal.

[0277] In some embodiments, the first field in the first flexible notification indication information is a second preset value, and the access network element first sends a first paging message to the terminal.

[0278] In some embodiments, the first paging message has a corresponding timer. When the timer of the first paging message has not expired, the access network element may repeatedly send the first paging message to the terminal until the maximum number of repetitions of the first paging message is reached or the timer of the first paging message expires.

[0279] In some embodiments, the timer of the first paging message may be sent in advance by the core network element to the access network element.

[0280] In some embodiments, the duration corresponding to the timer of the first paging message may be greater than or equal to the duration corresponding to a preset paging cycle.

[0281] S403: The access network element determines that the timer of the first paging message has expired and the access network element has not received a second response message from the terminal to the first paging message.

[0282] In some embodiments, the first field in the first flexible notification indication information is a second preset value, and when the core network element sends the first paging message to the terminal for the first time, the timer of the first paging message is started.

[0283] In some embodiments, the first field in the first elastic notification indication information is a second preset value. If the access network element receives the second response message before the timer of the first paging message expires, the access network element may not send the elastic notification message to the terminal.

[0284] S404: The access network element sends a flexible notification message to the terminal.

[0285] In some embodiments, the access network element sends a flexible notification message to the terminal when it determines that the timer of the first paging message has expired and the access network element has not received a second response message from the terminal to the first paging message.

[0286] In some embodiments, the elastic notification message may be sent repeatedly.

[0287] In some embodiments, the flexible notification message has a corresponding timer.

[0288] In some embodiments, the flexible notification message and the first paging message may reuse a timer.

[0289] In some embodiments, the timer of the elastic notification message may be sent by the core network element to the access network element.

[0290] In some embodiments, the elastic notification message can be sent repeatedly until the access network element receives the first response message of the terminal to the elastic notification message, or the timer of the elastic notification message expires, or the number of times the elastic notification message is sent reaches a preset first number of repetitions.

[0291] In some embodiments, the access network element sends a flexible notification message to the terminal for the first time, and a timer of the flexible notification message starts.

[0292] If the access network element does not receive the first response message before the timer of the elastic notification message expires, the access network element may repeatedly send the elastic notification message to the terminal until the timer of the elastic notification message expires or the number of times the elastic notification message is sent reaches a preset first repetition number.

[0293] In some embodiments, when the access network element sends the elastic notification message to the terminal in step S404, the access network element may further determine the elastic notification sending position and send the elastic notification message at the elastic notification sending position of the elastic notification frame.

[0294] In some embodiments, the access network element may determine elastic notification frame parameters, elastic notification quantity, service identifier of the elastic notification message, sending timing offset, terminal identifier, and elastic notification subgroup parameters.

[0295] In some embodiments, the access network element determines the elastic notification sending position on the elastic notification frame based on the elastic notification frame parameters, the number of elastic notifications, the service identifier of the elastic notification message, the sending timing offset, the terminal identifier, and the elastic notification subgroup parameters, so as to send the elastic notification message at the elastic notification sending position on the elastic notification frame.

[0296] In some embodiments, the access network element may also broadcast the elastic notification frame parameters, the number of elastic notifications, the service identifier of the elastic notification message, the sending timing offset, and the elastic notification subgroup parameters through a system message, so that the terminal can determine the elastic notification sending position on the elastic notification frame, and thus the terminal receives the elastic notification message at the elastic notification sending position on the elastic notification frame.

[0297] It can be understood that the access network element determines the elastic notification frame based on the elastic notification frame parameters, and the access network element determines the elastic notification sending position on the elastic notification frame based on the service identifier, elastic notification quantity, elastic notification subgroup parameters and sending timing offset of the elastic notification message. The method for the access network element to determine the elastic notification sending position on the elastic notification frame in step S303 is not repeated here.

[0298] It can be understood that the terminal determines the elastic notification frame based on the elastic notification frame parameters, accesses the network element and determines the elastic notification sending position on the elastic notification frame based on the service identifier, elastic notification quantity, elastic notification subgroup parameters and sending timing offset of the elastic notification message. The method for the terminal to determine the elastic notification sending position on the elastic notification frame in step S303 is not repeated here.

[0299] In some embodiments, steps S401, S403, and S404 can be replaced.
