[0215] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown herein can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0216] Research has revealed that paging failures can occur when terminal devices are in certain states or environments. For example, for satellite network terminals, due to severely limited link budgets, if the satellite terminal is placed in a relatively enclosed environment, such as inside a pocket or indoors, the network may be unable to page it using current or general paging methods. For terrestrial network terminals, if the terminal is in an environment with weak network signal, such as a basement or tunnel, the network may also be unable to page it. The term "current or general paging methods" refers to paging methods that do not require special processing or enhancement of paging message transmission and reception, or paging methods for terminal devices in a normal state (not in the aforementioned "certain states or environments").

[0217] In related technologies, a coverage enhancement mechanism is provided for certain types of terrestrial network terminals, such as enhanced machine-type communication (eMTC) devices and narrowband Internet of Things (NB-IoT) devices. Under the coverage enhancement mechanism, the paging success rate can be improved by repeatedly transmitting signals, channels, or signaling to these types of terrestrial network terminals, or by transmitting signals, channels, or signaling through power boosting. However, the application scope of this coverage enhancement mechanism is limited, and it cannot be applied to many terminal devices, such as satellite network terminals, and some terrestrial network terminals.

[0218] For example, in satellite network terminals, when paging is performed using repeated transmissions, the propagation delay of satellite communication is already quite large. Adding repeated transmissions would further increase the propagation delay, which is unacceptable in satellite communication. Furthermore, the constant movement of satellites in satellite communication can cause satellite switching. If a satellite switching occurs during repeated transmissions, the situation becomes even more complicated, leading to a further increase in propagation delay. Additionally, for power boosting, the bandwidth available in satellite communication is limited, and using power boosting for paging would further reduce the available bandwidth.

[0219] Therefore, finding a way to improve the paging success rate has become an urgent problem to be solved.

[0220] Based on the above research, this disclosure provides a method and apparatus for transmitting paging messages to solve the above problems.

[0221] The shortcomings of the above solutions are the result of the author's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure below should be considered as contributions made by the author to this disclosure.

[0222] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0223] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0224] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0225] To facilitate understanding of the technical solutions disclosed herein, the technical terms used in the embodiments of this disclosure will first be explained:

[0229] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0230] To facilitate understanding of this embodiment, a method for transmitting paging messages disclosed in this disclosure will first be described in detail.

[0231] See Figure 1 The diagram shows a flowchart of a paging message transmission method provided in this embodiment of the present disclosure. This paging message transmission method is applied to a terminal device. The method includes steps S101 to S102, wherein:

[0232] S101: Determine the method for receiving paging messages;

[0233] S102: Listen for paging messages in receiving mode; the paging message contains the device identifier of the terminal device.

[0234] In the paging message transmission method provided in this embodiment, the terminal device determines the paging message receiving method and listens to the paging message in the determined receiving method. This allows it to flexibly determine whether to listen to the paging message in an enhanced receiving method according to actual needs, ensuring that the paging message can be listened to in an enhanced sending method when needed, and in a non-enhanced sending method when not needed. This ensures both the success rate of paging when the terminal device is in certain states or environments and the smooth progress of the paging process in other states or environments.

[0235] The paging message transmission method provided in this disclosure will be described in detail below through several optional embodiments.

[0236] In one optional embodiment, the paging message is received in a first receiving manner.

[0237] The first receiving method includes, for example, an enhanced receiving method.

[0238] If the paging message receiving method is determined to be the first receiving method, the paging message can be monitored in the following ways:

[0239] Using the first receiving method, listen for paging messages on a preset physical channel.

[0240] Optionally, the enhanced reception method includes listening to paging messages on a preset physical channel.

[0241] Specifically, in one optional embodiment, when the terminal device listens for paging messages on a preset physical channel, for example, it listens for paging messages on the preset physical channel at a preset time. The preset time is either predetermined or determined based on configuration information.

[0242] If the preset time is set, it can be preset by the terminal device, or it can be a specific point in time determined based on absolute time after network access. For example, it can be based on network broadcast configuration or configuration sent to the terminal device by the network via dedicated signaling, and the time point is determined based on the configuration.

[0243] When the preset time is determined based on configuration information, this configuration information may include, for example, indication information for listening to paging messages. This indication information includes at least one of the following: a start time based on absolute time, paging cycle, paging duration, and advance or delay amount relative to the start time.

[0244] Based on this instruction and the absolute time, the preset time for monitoring the preset physical channel can be determined.

[0245] In another alternative embodiment, the terminal device may also receive configuration information for listening to paging messages.

[0246] Optionally, the configuration information may be obtained from the core network equipment during the registration process. Alternatively, the configuration information may also be obtained from the core network equipment during the tracking area update process. In 6G or future XG mobile communication networks, the relevant processes may not be referred to as registration or tracking area update processes; however, this does not constitute a limitation of the present invention. Generally, the configuration information can be obtained from the core network equipment through any communication process between the terminal equipment and the core network equipment.

[0247] The preset physical channel includes, for example, at least one of the following: physical data channel, physical control channel, and dedicated physical channel.

[0248] The physical data channel includes, for example, the Physical Downlink Shared Channel (PDSCH). The PDSCH is primarily used to transmit downlink user data between the base station and the user equipment (UE), such as data from web browsing, video streaming, and file downloads, and is a key channel for achieving high-speed data transmission. In this embodiment, paging messages can be sent using the PDSCH. The terminal device can listen for paging messages on the PDSCH in a first receiving mode. In 6G or future XG mobile communication networks, the physical data channel can refer to the physical channel transmitting physical downlink data, and is not necessarily named the Physical Downlink Shared Channel (PDSCH).

[0249] Physical control channels may include, for example, the Physical Downlink Control Channel (PDCCH). The PDCCH is a key physical channel in a wireless communication system responsible for transmitting downlink control information (DCI). In this embodiment, paging messages can also be sent using the PDCCH. The terminal device can listen for paging messages on the PDCCH in a first receiving mode. In 6G or future XG mobile communication networks, the physical control channel may refer to the physical channel transmitting physical downlink control information, and is not necessarily named Physical Downlink Control Channel (PDCCH).

[0250] A dedicated physical channel is, for example, a downlink physical channel that is distinct from other physical channels and specifically designed for transmitting paging messages. Paging messages can be sent using this dedicated physical channel. Terminal devices can listen for paging messages on this dedicated physical channel in a first receiving mode.

[0251] In one alternative embodiment, the first receiving method includes, for example, one or more of the following methods a1 to a3:

[0252] a1: Use the physical data channel to receive paging messages.

[0253] Here, when using the physical data channel to receive paging messages, the resources of the physical data channel are predefined or pre-configured resources.

[0254] Here, the resources of the physical data channel are predefined or pre-configured resources. When using the physical data channel to receive paging messages, it is not necessary to listen to the control channel to obtain scheduling information. Instead, the paging messages are received directly through the physical data channel based on the predefined or pre-configured resources.

[0255] a2: Use the physical control channel to receive paging messages.

[0256] Here, when receiving paging messages using the physical control channel, the physical control channel uses a first scrambling code for scrambling, and / or the physical control channel uses a first format to carry the device identifier.

[0257] Here, the first scrambling code includes, for example, a Radio Network Temporary Identifier (RNTI) for sending paging messages, specifically, a Paging Radio Network Temporary Identifier (PP-RNTI). In addition, the first scrambling code may also take other forms, which are not limited in this embodiment.

[0258] The first format is, for example, a specific Downlink Control Information (DCI) format, which can be set according to actual needs. Optionally, the physical control channel can use one format when carrying a device identifier, and another format when not carrying a device identifier.

[0259] a3: Use the dedicated physical channel for paging messages to receive paging messages.

[0260] Here, when using the dedicated physical channel for paging messages to receive paging messages, the dedicated physical channel for paging messages is only used to send paging messages.

[0261] Here, the dedicated physical channel for paging messages can send the identifier of one terminal device or the identifiers of multiple terminal devices when sending paging messages.

[0262] Since there is no resource indication information, when sending paging messages using a preset physical channel, the resources of the paging message must be fixed and cannot vary in length; the modulation scheme must also be fixed. Therefore, when sending paging messages based on a preset physical channel, the number of UE identifiers carried is usually fixed and cannot be variable. Specifically, the UE identifiers carried in the paging message can exist in any of the following situations:

[0263] First, set a maximum value, for example, the paging message can carry the identifiers of a maximum of n UEs. If the number of UEs being paged at the same time is less than n, the paging message can be padded with zeros or the UE identifiers can be repeated to make the paging message reach a certain length.

[0264] Second, resources are allocated in the frequency domain. For example, if n UEs need to be paged, n resources are allocated in the frequency domain. The UE determines its own paging resource from the n resources based on its own identifier.

[0265] Third, in the time domain, paging can be performed with random delays, in a round-robin fashion, or based on priority. In a round-robin fashion, if multiple UEs are being paged simultaneously, they are paged sequentially. In a priority-based fashion, paging is performed based on the service priority of the UE that triggered the paging.

[0266] Furthermore, in another alternative embodiment, the first receiving method may, for example, include at least one of the following b1 to b3:

[0267] b1: First modulation method; the modulation order of the first modulation method is less than a preset order threshold.

[0268] Specifically, the first modulation method can be, for example, a modulation method with a lower modulation order.

[0269] For example, paging messages that do not require enhanced transmission can use 16-QAM (Quadrature Amplitude Modulation) modulation techniques, or even higher modulation orders like 256-QAM, when transmitted using PDSCH. However, paging messages that require enhanced transmission may use physical channel modulation techniques such as OOK (On-Off Keying), BPSK (Binary Phase Shift Keying), or QPSK (Quadrature Phase Shift Keying), which have lower modulation orders and are easier to receive.

[0270] b2: First encoding method; the encoding rate of the first encoding method is less than the preset encoding rate threshold.

[0271] Specifically, the first encoding method could be, for example, an encoding method with a lower encoding rate.

[0272] In some embodiments, the coding rate may also be referred to as coding efficiency.

[0273] The coding rate refers to the proportion of useful information in the encoded data stream during signal processing. It represents the percentage of useful (non-redundant) data in the total encoded data. The coding rate can be calculated by dividing the number of information bits by the number of code elements in a code group. If the coding rate is k / n, then for every k bits of useful information, the encoder generates a total of n bits of data, where nk is redundant. Therefore, the higher the coding rate, the fewer redundant bits, the worse the fault tolerance, and the more difficult it is to receive data. Thus, for paging messages that do not require enhanced transmission, a larger coding rate can be used to improve resource utilization efficiency; while for paging messages that require enhanced transmission, a smaller coding rate can be used for physical channel transmission, increasing resource consumption but improving the reception success rate.

[0274] b3: Coverage enhancement method.

[0275] Coverage enhancement methods include, for example, one or two of the following: repeated transmission, power enhancement, etc.

[0276] Repeated transmission refers to repeatedly transmitting the paging message signal, channel, or signaling to increase the probability that the terminal device will receive the paging message. Power boosting, also known as power enhancement, includes at least one of the following: Reference Signal Power Boosting (RS Boosting), power amplifier technology, dynamic power sharing technology, opportunistic power boosting technology, etc.

[0277] In addition, in another optional embodiment, the first receiving methods shown in a1 to a3 above and the first receiving methods shown in b1 to b3 above can be used in combination. In the process of using them in combination, the number of the first receiving methods shown in a1 to a3 included in the combination can be one or more; and the number of the first receiving methods shown in b1 to b3 included in the combination can be one or more.

[0278] For example, a1 and b1 can be combined; or a1, b2 and b3 can be combined; or a1, b1, b2 and b3 can be combined; or a1, a2 and b1 can be combined; or a2, a3, b1 and b3 can be combined. The specific combination method is not limited in this embodiment.

[0279] Taking the combination of one of the first receiving methods shown in a1 to a3 and one of the first receiving methods shown in b1 to b3 as an example:

[0280] When the first receiving methods shown in a1 and b1 are combined, the determined receiving method is, for example, receiving the paging message using a physical data channel, wherein the resources of the physical data channel are predefined or pre-configured resources, and the paging message transmitted through the physical data channel is modulated using the first modulation method.

[0281] In the case of the first receiving method combination shown in a1 and b2 above, the determined receiving method is, for example, receiving the paging message using a physical data channel, wherein the resources of the physical data channel are predefined or pre-configured resources, and the paging message transmitted through the physical data channel is encoded using the first encoding method.

[0282] In the case of the first receiving method combination shown in a1 and b3 above, the determined receiving method is, for example, receiving paging messages using a physical data channel, wherein the resources of the physical data channel are predefined or pre-configured resources, and the paging messages transmitted through the physical data channel employ a coverage enhancement method.

[0283] In the case of the first receiving method combination shown in a2 and b1 above, the paging message is received using a physical control channel, the physical control channel is scrambled using a first scrambling code, and / or the physical control channel carries the device identifier using a first format, and the paging message transmitted through the physical control channel is modulated using a first modulation method.

[0284] In the case of the first receiving method combination shown in a2 and b2 above, the paging message is received using a physical control channel, the physical control channel is scrambled using a first scrambling code, and / or the physical control channel carries the device identifier using a first format, and the paging message transmitted through the physical control channel is encoded using a first encoding method.

[0285] In the case of the above combination of a2 and b3, the first receiving method is, for example, receiving the paging message using a physical control channel, the physical control channel using a first scrambling code for scrambling, and / or, the physical control channel using a first format to carry the device identifier, and the paging message transmitted through the physical control channel is sent using a coverage enhancement method.

[0286] When the first receiving methods shown in a3 and b1 are combined, the determined receiving method is, for example, receiving the paging message using a dedicated physical channel for paging messages, and the paging message transmitted through the dedicated physical channel is modulated using the first modulation method.

[0287] When the first receiving methods shown in a3 and b2 are combined, the determined receiving method is, for example, receiving the paging message using a dedicated physical channel for paging messages, and encoding the paging message through the dedicated physical channel using the first encoding method.

[0288] When the first receiving methods shown in a3 and b3 are combined, the determined receiving method is, for example, receiving the paging message using a dedicated physical channel for paging messages, and transmitting the paging message transmitted through the dedicated physical channel using a coverage enhancement method.

[0289] Other combinations are similar, and will not be described in detail in the embodiments disclosed herein.

[0290] Optionally, a combination of a first modulation scheme and a first coding scheme can be indicated by a modulation and coding scheme indication information, wherein the modulation order of the first modulation scheme is less than a preset order threshold, and the coding rate of the first coding scheme is less than a preset coding rate threshold.

[0291] In another alternative embodiment, when listening for paging messages on a preset physical channel in a first receiving mode, the following process may be employed, for example:

[0292] Listen to the pilot signal;

[0293] After detecting the pilot signal, the paging message is monitored on the preset physical channel using the first receiving method.

[0294] In practice, pilot signals provide crucial reference information to the UE during paging, such as synchronization and channel information, helping the UE accurately receive paging messages in complex wireless environments. The UE obtains channel state information by listening to pilot signals, enabling it to correctly demodulate and decode paging messages.

[0295] In this embodiment, after receiving a pilot signal, the terminal device listens for paging messages on a preset physical channel using a first receiving method. During this process, the UE can continuously listen to the pilot signal to perform channel estimation. The pilot signal is transmitted on specific time-frequency resources. Based on the strength, phase, and other information of the received pilot signal, the UE estimates the characteristics of the preset physical channel, such as channel attenuation and multipath effects. Then, based on these channel estimation results, the UE performs equalization and other processing on the received paging messages to improve the accuracy of paging message reception.

[0296] In another possible embodiment, the method for determining whether to receive the paging message in the first receiving mode may be as follows:

[0297] If it is determined that the terminal device is in a preset state, it is determined that the paging message needs to be received through the first receiving method;

[0298] The preset states include at least one of the following c1 to c5:

[0299] c1: The terminal device cannot obtain downlink synchronization based on the preset method.

[0300] Specifically, achieving downlink synchronization typically refers to the UE synchronizing with the downlink signals transmitted by the base station during communication, enabling the UE to accurately receive and interpret downlink data and control information from the base station. In other words, the UE must maintain consistency with the base station's downlink signals in time and frequency to ensure the correct identification and processing of various information within the downlink signals, such as pilot signals, synchronization signals, and data signals.

[0301] In this embodiment, downlink synchronization cannot be obtained using a preset method, such as conventional methods. For example, in a 4G LTE subsystem, downlink synchronization is obtained based on the primary and secondary synchronization signals, or using a reference signal; or in a 5G NR system, downlink synchronization is obtained based on a synchronization signal block, etc. However, downlink synchronization can usually be obtained by listening to pilot signals as described in the above embodiments. Therefore, when downlink synchronization cannot be obtained using conventional methods, it is determined that a paging message needs to be received using a first receiving method.

[0302] c2: The terminal device cannot obtain a valid system message.

[0303] c3: The terminal device is unable to complete the cell stay.

[0304] c4: The terminal device failed to update the Tracking Area (TA).

[0305] Specifically, terminal devices may be unable to obtain valid system information, complete cell camping, or successfully perform TA updates under conditions such as weak network signal strength, network congestion, network failure, or external electromagnetic interference. Furthermore, the aforementioned situations may occur when terminal devices enter specific environments, such as ground terminal devices in a basement or satellite terminal devices in an enclosed space. Therefore, when any of the above-mentioned c2 to c4 occurs, it is determined that paging messages need to be received via the first receiving method.

[0306] c5: The terminal device is operating in a non-terrestrial network.

[0307] Non-terrestrial networks (NTNs) mainly include satellite networks, high-altitude platform networks, and unmanned aerial vehicle (UAV) networks. In NTN networks, signals are attenuated due to atmospheric absorption and scattering during long-distance transmission and passage through the atmosphere, resulting in weak signal strength received by terminal equipment. Therefore, to ensure the reliability of paging, when terminal equipment is operating in a non-terrestrial network, it is determined that paging messages must be received through a primary receiving method.

[0308] In another optional embodiment, in the paging message transmission method provided in this disclosure, the terminal device will also send indication information to the access network device and / or the core network device;

[0309] The instruction information is used to instruct the paging message to be sent in the first sending mode corresponding to the first receiving mode.

[0310] Specifically, when the terminal device determines that it is listening for paging messages in the first receiving mode, it informs the access network device and / or the core network device of its status by sending an indication message to the access network device and / or the core network device. This indication message instructs the access network device to send the paging message in the first sending mode corresponding to the first receiving mode.

[0311] Optionally, the UE may send an indication message to the network device before determining that it is about to enter an emergency environment (an environment with very poor link quality), indicating that the UE is about to enter an emergency environment. This allows the network device to determine, based on the indication message, that the UE's paging message needs to be sent via the first transmission method.

[0312] Optionally, if the terminal device determines that it will not use or has exited the use of the first receiving method to listen for paging messages, it may inform the access network device and / or the core network device of its status by sending an indication message to the access network device and / or the core network device. This indication message can instruct the access network device not to send paging messages using the first receiving method, or to exit the first sending method corresponding to the first receiving method.

[0313] Optionally, after determining that it is about to leave a critical environment (an environment with poor link quality), the UE may send an indication message to the network device, indicating that the UE has left the critical environment. This allows the network device to determine, based on the indication message, that the UE's paging messages will no longer be sent via the first transmission method.

[0314] In this way, the paging message sending and receiving methods between the terminal device and the network-side device (including access network device and core network device) are synchronized through paging messages, ensuring consistency between the terminal device and the network-side device in the paging process and avoiding paging failures caused by inconsistencies in their paging methods.

[0315] In another optional embodiment, in the paging message transmission method provided in this disclosure, the terminal device may also send capability indication information to the access network device and / or the core network device.

[0316] This capability indication information is used to instruct the terminal device to support receiving paging messages in the first receiving mode. Thus, when either the access network device or the core network device determines that it needs to send a paging message in the first sending mode, it can determine from this capability indication information that the terminal device has the capability to receive paging messages using the first receiving mode corresponding to the first sending mode.

[0317] The UE can send the aforementioned capability indication information through the registration process or any other communication process between the UE and the core network equipment. In this case, the capability indication information is sent to the core network equipment. Optionally, the UE can send the capability indication information to the access network equipment.

[0318] In another optional embodiment of this disclosure, after receiving the paging message in a first receiving mode, the terminal device may further execute at least one of the following three processes:

[0319] Access to the network;

[0320] Select or reselect a cell;

[0321] Perform the registration process.

[0322] Specifically, if the UE detects a paging message sent in enhanced transmission mode, the UE can directly attempt to access the network without needing to detect paging messages sent in normal mode to determine if the network is actually paging the UE. Here, the UE can attempt to access the network after the channel conditions of the UE have improved.

[0323] If the UE detects a paging message sent in enhanced transmission mode, it can perform cell selection or reselection; optionally, after cell selection or reselection, it can perform a registration process to notify the network that the UE is already online.

[0324] In another optional embodiment, the paging message receiving method further includes a second receiving method. This second receiving method includes, for example, a non-enhanced receiving method. The non-enhanced receiving method is, for example, a receiving method other than an enhanced receiving method.

[0325] Listening for paging messages in a defined paging message reception method, including:

[0326] The paging message is received on the second physical data channel using the second receiving method, and the receiving method of the paging message on the second physical data channel is configured by the second physical control channel.

[0327] Here, the second physical data channel includes, for example, the PDSCH. The second physical control channel includes, for example, the PDCCH.

[0328] Specifically, paging messages can be listened to through a first receiving method and / or a second receiving method, which may include any one of the following d1 to d3:

[0329] d1: Listen for paging messages using the first receiving method.

[0330] In this way, even when the link conditions of the terminal device are poor, the paging message can be monitored by enhancing the reception method, ensuring that the paging message can be successfully received under such circumstances.

[0331] d2: Listen for paging messages via the second receiving method.

[0332] In this way, when the link conditions of the terminal device are good, paging messages can be monitored through non-enhanced reception, ensuring resource utilization.

[0333] d3: While listening to paging messages using the first receiving method, simultaneously monitor paging messages using the second receiving method.

[0334] In this way, by simultaneously monitoring paging messages using both enhanced and non-enhanced reception methods, paging failures can be avoided when the terminal device and the network-side device have inconsistent understandings of the terminal device's environment.

[0335] See Figure 2 The diagram shows a flowchart of another paging message transmission method provided in this embodiment of the present disclosure. This paging message transmission method is applied to a core network device. The method includes steps S201 to S202, wherein:

[0336] S201: Determine the method for sending the paging message;

[0337] S202: Send a paging message to the access network device; the paging message includes indication information; the indication information is used to instruct the access network device to send the paging message in a determined paging message sending method; the paging message contains the device identifier of the terminal device.

[0338] In the paging message transmission method provided in this embodiment, after determining the paging message transmission method, the core network device sends a paging message to the access network device. This paging message includes indication information, which instructs the access network device to send the paging message to the terminal device using the determined paging message transmission method. This allows the core network device to flexibly determine whether to send the paging message in an enhanced transmission mode based on actual needs, ensuring that the enhanced transmission mode is used when needed, while the non-enhanced transmission mode is used when not needed. This approach guarantees a high success rate for paging when the terminal device is in certain states or environments, and also ensures smooth paging processes in other states or environments.

[0339] The above-described paging message transmission method will now be described in detail through various optional embodiments.

[0340] In practice, the paging message is sent in the following ways: a first sending method. This first sending method includes an enhanced sending method.

[0341] In this case, the indication information carried in the paging message sent by the core network equipment to the access network is used to indicate the first transmission method, which is to send the paging message on a preset physical channel.

[0342] In one optional embodiment, the first transmission method includes one or more of the following methods: transmitting a paging message using a physical data channel, transmitting a paging message using a physical control channel, and transmitting a paging message using a dedicated physical channel for paging messages;

[0343] When using a physical data channel to send paging messages, the resources of the physical data channel are predefined or pre-configured resources;

[0344] When using the physical control channel to send paging messages, the physical control channel uses a first scrambling code for scrambling, and / or the physical control channel uses a first format to carry the device identifier;

[0345] When using the dedicated physical channel for paging messages to send paging messages, the dedicated physical channel for paging messages is only used for sending paging messages.

[0346] In another alternative embodiment, the first transmission method includes at least one of the following:

[0347] First modulation method; the modulation order of the first modulation method is less than a preset order threshold;

[0348] A first encoding method; the encoding rate of the first encoding method is less than a preset encoding rate threshold;

[0349] Coverage enhancement methods.

[0350] Here, the first transmission method and the preset physical channel can be specifically referred to in the above. Figure 1 The descriptions of the first receiving method and the preset physical channel in the corresponding embodiments will not be repeated here.

[0351] In another alternative embodiment, it is determined that a pager for the terminal device needs to be sent via the first transmission method when at least one of the following e1 to e3 occurs:

[0352] e1: The number of times the paging terminal device has failed has reached the preset number.

[0353] e2: Received instruction information sent by the terminal device; the instruction information indicates that the terminal device should be paged through the first receiving method.

[0354] Here, if an instruction message is received from the terminal device, it indicates that the terminal device has determined that it needs to page the terminal device using an enhanced paging method. In this case, it is determined that the terminal device will be paged using the first sending method.

[0355] e3: The terminal device operates in a non-terrestrial network.

[0356] In practical implementation, the method for sending paging messages can be determined internally by the core network equipment. For example, if the core network equipment attempts to page the UE multiple times without success (i.e., when situation e1 occurs), the terminal device may be operating in an environment with poor link quality. In this case, to successfully page the terminal device, the UE's paging message can be considered to require enhanced transmission. Alternatively, the UE can notify the core network equipment. For instance, before entering an environment with poor channel quality, the UE can send an indication message to the core network equipment to indicate that it is about to enter an environment with very poor channel quality. That is, when situation e2 occurs, the network can adopt an enhanced transmission method when paging the UE.

[0357] In another alternative embodiment, the core network device may also send configuration information for listening to paging messages to the terminal device and / or access network device.

[0358] The configuration information includes indication information for listening to paging messages. The indication information includes at least one of the following: the start time based on absolute time, the paging cycle, the paging duration, and the advance or delay amount relative to the start time.

[0359] Optionally, the configuration information for listening to paging messages can be sent during the terminal device registration process or during any communication between the terminal device and the core network device. When sending, this configuration information can be sent to the terminal device.

[0360] Optionally, the configuration information for listening to paging messages can be sent to the access network device. The access network device determines, based on actual circumstances, when and / or when to send the configuration information to the terminal device.

[0361] After receiving the configuration information, the terminal device can determine the preset time for listening to paging messages on the preset physical channel based on at least one of the absolute time start time, paging cycle, paging duration, advance amount or delay amount relative to the start time indicated by the indication information carried in the configuration information, thereby realizing the listening to paging messages on the preset physical channel based on the first receiving method.

[0362] In another optional embodiment, the core network device will also receive capability indication information from the terminal device; the capability indication information is used to indicate that the terminal device supports sending paging messages using a first transmission method.

[0363] In this case, when the core network device determines that it needs to page the terminal device in the first transmission mode, it determines that the terminal device supports sending paging messages in the first transmission mode according to the capability indication information. At this time, the core network device will send a paging message to the access network device and carry indication information in the paging message to instruct the access network device to send the paging message to the terminal device in the first transmission mode on a preset physical channel.

[0364] In another optional embodiment, the paging message may further include paging indication information. This paging indication information instructs the access network device to send a paging message to the terminal device simultaneously in a first sending mode and in a second sending mode; the second sending mode includes a non-enhanced sending mode.

[0365] In practice, there may be discrepancies in the core network equipment's and the UE's understanding of the UE's state. For example, the core network equipment may believe the UE can page the UE normally, while the UE requires an enhanced method to receive the paging message; or the core network equipment may believe the UE needs to page the UE in an enhanced manner, while the UE can receive the paging message normally. By simultaneously sending paging messages to the terminal device using both the first and second transmission methods, the core network equipment can send paging messages in both the enhanced and normal methods simultaneously, thus avoiding paging failures caused by inconsistencies in the core network equipment's and UE's understanding of the UE's state.

[0366] See Figure 3 The diagram shows a flowchart of another paging message transmission method provided in this embodiment of the present disclosure. The paging message transmission method provided in this embodiment of the present disclosure is applied to an access network device. The method includes steps S301 to S302, wherein:

[0367] S301: Determine the method for sending the paging message;

[0368] S302: Send a paging message in a defined paging message sending method; the paging message contains the device identifier of the terminal device.

[0369] In the paging message transmission method provided in this embodiment, after determining the paging message transmission method, the access network device sends the paging message to the terminal device in the determined paging message transmission method. Thus, the access network device can flexibly determine whether to send the paging message in an enhanced transmission method according to the actual needs, so as to ensure that the paging message can be sent in an enhanced transmission method when needed, and in a non-enhanced transmission method when not needed. This can ensure the success rate of paging when the terminal device is in certain states or environments, and also ensure the smooth progress of the paging process in other states or environments.

[0370] The paging message transmission method described above will be explained in detail below through various optional embodiments.

[0371] In one optional embodiment, the paging message is sent in a manner including: a first sending method; the first sending method includes: an enhanced sending method;

[0372] Sending paging messages in a defined paging message sending method, including:

[0373] The paging message is sent on a preset physical channel using the first transmission method.

[0374] Optionally, the first transmission method includes one or more of the following methods: transmitting paging messages using a physical data channel, transmitting paging messages using a physical control channel, and transmitting paging messages using a dedicated physical channel for paging messages;

[0375] When using a physical data channel to send paging messages, the resources of the physical data channel are predefined or pre-configured resources;

[0376] When using the physical control channel to send paging messages, the physical control channel uses a first scrambling code for scrambling, and / or the physical control channel uses a first format to carry the device identifier;

[0377] When using the dedicated physical channel for paging messages to send paging messages, the dedicated physical channel for paging messages is only used for sending paging messages.

[0378] Optionally, the first transmission method includes at least one of the following:

[0379] First modulation method; the modulation order of the first modulation method is less than a preset order threshold;

[0380] A first encoding method; the encoding rate of the first encoding method is less than a preset encoding rate threshold;

[0381] Coverage enhancement methods.

[0382] Here, the first transmission method and the preset physical channel can be specifically referred to in the above. Figure 1 The descriptions of the first receiving method and the preset physical channel in the corresponding embodiments will not be repeated here.

[0383] In one alternative embodiment, when sending a paging message on a preset physical channel in a first transmission mode, the following method may be used, for example:

[0384] A paging message is created at the radio resource control layer and mapped to the paging channel via the paging control channel; wherein, when mapping to each channel layer, preset indication information is carried, and the preset indication information indicates that the paging message is sent in the first sending mode;

[0385] The paging message is mapped from the paging channel to the selected preset physical channel, and the paging message is sent according to the transmission method corresponding to the preset physical channel.

[0386] Here, because the protocol stack may change in a communication system, the number of protocol layers corresponding to the stack may also change. Some communication systems may have a large number of protocol layers, while others may have a small number, and even the names of the protocol layers, the division of logical channels and transport channels may change. Therefore, in this embodiment, when mapping the paging message to the paging channel via the paging control channel, the specific number of layers above the physical layer is not considered; only the indication information obtained from the upper physical layer is considered, and the paging message is transmitted using a preset physical channel based on this indication information. Optionally, within the access device, from the generation of the paging message to its transmission through the preset physical channel, it may pass through several protocol layers, such as: protocol layer 1, protocol layer 2, ..., protocol layer 3, and the preset physical channel. Therefore, when transmitting a protocol data unit containing a paging message from protocol layer n to protocol layer n+1, it is necessary to indicate that the paging message is transmitted in the first transmission mode. For example, when transmitting a protocol data unit containing a paging message from protocol layer 1 to protocol layer 2, it carries indication information, which is used to indicate that the paging message is transmitted in the first transmission mode.

[0387] During the paging message mapping process, preset indication information is carried when mapping to each protocol layer or channel. This preset indication information is used to indicate that the paging message is sent in the first transmission mode. After the paging message is mapped or transmitted to the paging channel, a preset physical channel is determined according to the preset indication information, and the paging message is sent to the terminal device according to the paging message transmission mode corresponding to the preset physical channel.

[0388] like Figure 4 In the example shown, after determining that the UE needs to use enhanced paging, the access network device creates a paging message and simultaneously creates indication information. This indication information instructs the enhanced paging message to be sent, i.e., paging the UE using enhanced paging. During the mapping or transmission of this paging message from the Paging Control Channel (PCCH) to the Paging Channel (PCH), the indication information is also mapped or transmitted to the PCH along with the paging message. Then, based on whether the indication information is carried during the mapping process, it is determined whether the enhanced paging message transmission process needs to be executed. If it is determined that the enhanced paging message transmission process needs to be executed, a preset physical channel for executing the enhanced paging message transmission is determined from at least one of the PDSCH, PDCCH, and Physical Paging Channel (PPCH). The paging message is then sent from the determined preset physical channel to the terminal device according to the transmission method corresponding to each preset physical channel.

[0389] In another embodiment of this disclosure, if the transmission method is not enhanced, the aforementioned preset indication information may not be carried during the mapping process. In this case, the paging message can be sent using the second transmission method.

[0390] Optionally, regardless of whether the paging message is sent via the first sending method, the above mapping or transmission process always carries preset indication information, which indicates whether the first sending method or the second sending method is used by indicating 0 or 1 through the preset indication information; for example, when the preset indication information indicates 0, the first sending method is used; when the preset indication information indicates 1, the second sending method is used.

[0391] In another alternative embodiment, the method of sending the paging message can be determined in the following manner:

[0392] Instructions on the paging message sending method of the receiving terminal device;

[0393] Determine the method of sending the paging message based on the instruction information;

[0394] The instruction information includes at least one of the following:

[0395] Instruction information received from core network equipment or terminal equipment;

[0396] Indication information generated internally by the access network device.

[0397] Specifically, the process by which the terminal device sends indication information to the access network device can be found in the above description. Figure 1 The specific process of the core network device sending indication information to the access network device can be found in the descriptions of the various optional embodiments above. Figure 2 The specific descriptions of the corresponding optional embodiments and the detailed process of generating indication information internally by the access network device can be found above. Figure 3 The specific descriptions of the corresponding optional embodiments will not be repeated here.

[0398] The access network device generates an indication message after at least one of the following events occurs:

[0399] The number of times the paging terminal device has failed has reached the preset number;

[0400] It was determined that the terminal device was operating in a non-terrestrial network.

[0401] In another optional embodiment, before sending the paging message through the preset physical channel in the first transmission mode, the method further includes: sending a pilot signal for the preset physical channel.

[0402] This can be a pilot signal, which is optional. Alternatively, other signals, such as a waking-up signaling (WUS), can be sent before sending a paging message on a preset physical channel.

[0403] Optionally, the pilot signal or WUS signal needs to be transmitted with enhancement. Only if the terminal device successfully detects the pilot signal or successfully receives the WUS signal will it determine whether to subsequently send its paging message on the preset physical channel, or receive the paging message through the preset physical channel.

[0404] In another optional embodiment, a paging message is transmitted on a preset physical channel using a first transmission method, including:

[0405] The paging message is sent at a preset time using the first sending method; the preset time is either preset or determined based on configuration information.

[0406] The method for determining the preset time can be found above. Figure 1 and Figure 2 The descriptions of the corresponding optional embodiments will not be repeated here.

[0407] In another optional embodiment, the paging message transmission method provided in this disclosure further includes:

[0408] The terminal device receives capability indication information; the capability indication information is used to indicate that the terminal device supports receiving paging messages in the first receiving mode corresponding to the first sending mode.

[0409] After obtaining the capability indication information sent by the terminal device, if the access network device determines that it needs to send a paging message in the first sending mode, it determines that the terminal device has the capability to receive paging messages in the first sending mode based on the capability indication information, so that it can use the first sending mode when sending paging messages.

[0410] In another optional embodiment, the paging message transmission method provided in this disclosure further includes:

[0411] While sending a paging message to the terminal device using the first sending method, a paging message is also sent to the terminal device using the second sending method.

[0412] The second transmission method includes: non-enhanced transmission method.

[0413] In this way, by simultaneously sending paging messages to the terminal device using both the first and second sending methods, the access network device can send paging messages to the terminal device in both enhanced and non-enhanced methods while sending paging messages in enhanced mode, thus avoiding paging failures caused by inconsistencies in the access network device's and the UE's understanding of the UE's state.

[0414] The technical solution provided in this disclosure still uses the conventional paging message format before the physical layer. Only when the physical layer is used does it use the preset physical channel or the transmission method corresponding to the preset physical channel to send the paging message. This results in greater reusability compared to the conventional paging message transmission method (non-enhanced transmission method).

[0415] Those skilled in the art will understand that, in the above-described method of the specific implementation, the order in which each step is written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.
