[0048] The paging method provided in the embodiments of the present application is described in detail below through some embodiments and application scenarios in conjunction with the accompanying drawings.

[0049] Referring to FIG2 , an embodiment of the present application provides a paging method, which is executed by a network-side device and includes:

[0050] Step 201: The network side device sends a first paging message to the terminal;

[0051] The relevant information of the first paging message is different from the relevant information of the second paging message. The first paging message is a paging message used for data plane paging, and the second paging message is a paging message used for non-data plane paging.

[0052] The above-mentioned first paging message is a paging message for data plane paging, and the above-mentioned second paging message is a paging message for non-data plane paging. The second paging message can be understood as an existing paging message. The relevant information of the above-mentioned first paging message and the relevant information of the second paging message specifically refer to information associated with the paging message, such as the message category of the paging message, the indication information in the downlink control information (DCI) corresponding to the paging message, the logical channel identity (LCID) used by the paging message, and the time-frequency resources or transmission channel of the paging message.

[0053] In an embodiment of the present application, the network sends a first paging message to the terminal, wherein the relevant information of the first paging message is different from the relevant information of the second paging message. The first paging message is a paging message for data plane paging, and the second paging message is a paging message for non-data plane paging. By using a paging message different from the non-data plane paging, data plane paging is implemented on the terminal side. The terminal side can determine whether the paging is data plane paging or non-data plane paging based on the paging message, and thus adopt a corresponding strategy for subsequent processing.

[0054] In a possible implementation, the relevant information of the first paging message is different from the relevant information of the second paging message and includes one or more of the following:

[0055] (1) The message categories of the first paging message and the second paging message are different;

[0056] Optionally, the first paging message can be recorded as pagingDP, and the second paging message can be recorded as paging, that is, data plane paging and non-data plane paging use different paging messages. It should be noted that the parameters of the pagingDP message can be reused with the existing paging message or newly defined.

[0057] (2) The setting value of the first information field of the DCI corresponding to the first paging message is different from the setting value of the first information field of the DCI corresponding to the second paging message;

[0058] Optionally, the above-mentioned first information field can be a short message field, that is, the Short Message field is used in the DCI corresponding to the paging message to indicate whether the Paging is used for the data plane. For example, a value of 0 represents a normal paging message, and a value of 1 represents a data plane paging message, so that the terminal can distinguish whether the paging message received this time is the first paging message for the data plane or the second paging message for the second data plane.

[0059] (3) The LCID used in the first paging message is different from the LCID used in the second paging message;

[0060] The network side can set different LCIDs for different paging messages. For example, the newly added LCID1 represents a normal paging message, and LCID2 represents a paging message used for the data plane.

[0061] (4) The time domain resources of the first search space configured for the first paging message are different from the time domain resources of the second search space configured for the second paging message;

[0062] A dedicated search space is set for data plane paging to distinguish data plane paging from existing paging in the time domain.

[0063] (5) The frequency domain resources of the first search space configured for the first paging message are different from the frequency domain resources of the second search space configured for the second paging message;

[0064] A dedicated search space is set for data plane paging, thereby distinguishing data plane paging from existing paging in the frequency domain.

[0065] (6) The first channel for transmitting the first paging message is different from the second channel for transmitting the second paging message.

[0066] A new transport channel is defined for data plane paging. The differences between this transport channel and the existing paging channel (PCH) include but are not limited to the following aspects:

[0067] (a) Time domain resources;

[0068] (b) frequency domain resources;

[0069] (c) multiplexing method;

[0070] (d) Radio Network Temporary Identity (RNTI)

[0071] In one possible implementation, the method further includes:

[0072] (1) After the network side device sends the first paging message, if a first preset time period has elapsed and the network side device has not received a response message to the first paging message from the paged terminal, the network side device stops the data plane service of the paged terminal;

[0073] The above-mentioned first preset duration can be specifically implemented through a counter or timer, that is, after the network side device sends the first paging message, the counter or timer is started. When the counter reaches the preset count or the timer times out, if the terminal does not respond to the paging, the data plane service of the paged terminal is stopped; if the terminal responds to the paging before the counter reaches the preset count or the timer times out, the counter is reset or the timer is stopped.

[0074] (2) The network-side device updates the data plane context of the paged terminal and sets the data plane capability of the paged terminal to suspend;

[0075] (3) After the network side device sets the data plane capability of the paged terminal to suspended, when a second preset duration is reached and the paged terminal enters the connected state, the network side device obtains the data plane capability of the paged terminal;

[0076] (4) The network-side device updates the data plane context of the paged terminal based on the acquired data plane capabilities.

[0077] The second preset duration can be implemented by a counter or timer similarly to the first preset duration. The purpose of setting the second preset duration is to prevent the terminal from immediately acquiring the data plane capability of the terminal whenever the terminal does not respond to the paging, thereby avoiding excessive power consumption.

[0078] In one possible implementation, the method further includes:

[0079] (1) After the network side device sends the first paging message, when a third preset time period has expired and the network side device has not received a response message to the first paging message from the paged terminal, the network side device deletes the data plane context of the paged terminal;

[0080] At this point, the network-side device believes that the terminal does not support data.

[0081] (2) When the paged terminal enters the connected state, the network-side device obtains the data plane capabilities of the paged terminal;

[0082] (3) The network-side device updates the data plane context of the paged terminal based on the acquired data plane capabilities.

[0083] It should be noted that the above processing method is for data plane paging, and the network side can still initiate paging other than data plane paging to the UE normally. In the above processing method, the default premise is that the data plane capability is actively obtained by the network side, and the UE will not actively report when the capability changes.

[0084] In one possible implementation, the method further includes:

[0085] In a case where the network side device sends the first paging message and the second paging message, the network side device receives the first message from the paged terminal;

[0086] The first message is a message sent by the paged terminal during a random access process, and the second information field in the first message is used to instruct the paged terminal to respond to the first paging message or the second paging message.

[0087] In an embodiment of the present application, considering that the network side device can send both a first paging message and a second paging message to the terminal, the terminal performs random access after responding to the paging, and indicates through the message in the random access process whether the terminal responds to the first paging message or the second paging message, or both.

[0088] When the UE receives both normal paging and data plane paging sent by the network, it can decide to respond to both or only respond to one of them according to the priority, depending on the UE status and policy. Because it may affect the settings of rrcSetup or rrcResume, for the 4-step random access scenario, consider further subdividing mt-Access in the cause of message 3 (MSG3), such as mt-AccessNormal, mt-AccessDP, and mt-AccessBoth, which respectively represent normal paging services and data plane paging services, and can respond to normal paging and data plane paging at the same time; for the 2-step random access scenario, consider setting information indicating normal paging services, data plane paging services, or can respond to normal paging and data plane paging at the same time in message A (MSGA).

[0089] Referring to FIG3 , an embodiment of the present application provides a paging method, which is performed by a terminal and includes:

[0090] Step 301: The terminal receives a first paging message from a network-side device;

[0091] Step 302: The terminal responds or does not respond to the first paging message according to a preset policy;

[0092] The relevant information of the first paging message is different from the relevant information of the second paging message, and the second paging message is a paging message used for non-data plane paging.

[0093] The above-mentioned first paging message is a paging message for data plane paging, and the above-mentioned second paging message is a paging message for non-data plane paging. The second paging message can be understood as an existing paging message. The relevant information of the above-mentioned first paging message and the relevant information of the second paging message specifically refer to information associated with the paging message, such as the message category of the paging message, the indication information in the downlink control information (DCI) corresponding to the paging message, the logical channel identity (LCID) used by the paging message, and the time-frequency resources or transmission channel of the paging message.

[0094] It should be noted that when a terminal receives a paging message sent by a network-side device, it needs to determine whether the paging is a data plane paging or a non-data plane paging based on the type of the paging message or the relevant information of the paging message. After determining the type of paging, it decides whether to respond to the paging based on the preset policy.

[0095] The above-mentioned preset policy refers to a policy for whether to respond to data plane paging, and can be set in the terminal in a pre-configured or pre-defined manner.

[0096] In an embodiment of the present application, the network sends a first paging message to the terminal, wherein the relevant information of the first paging message is different from the relevant information of the second paging message. The first paging message is a paging message for data plane paging, and the second paging message is a paging message for non-data plane paging. By using a paging message different from the non-data plane paging, data plane paging is implemented on the terminal side. The terminal side can determine whether the paging is data plane paging or non-data plane paging based on the paging message, and thus adopt a corresponding strategy for subsequent processing.

[0097] In a possible implementation, the relevant information of the first paging message is different from the relevant information of the second paging message and includes one or more of the following:

[0098] (1) The message categories of the first paging message and the second paging message are different;

[0099] Optionally, the first paging message can be recorded as pagingDP, and the second paging message can be recorded as paging, that is, data plane paging and non-data plane paging use different paging messages. It should be noted that the parameters of the pagingDP message can be reused with the existing paging message or newly defined.

[0100] (2) The setting value of the first information field of the DCI corresponding to the first paging message is different from the setting value of the first information field of the DCI corresponding to the second paging message;

[0101] Optionally, the above-mentioned first information field can be a Short Message field, that is, the Short Message field is used in the DCI corresponding to the paging message to indicate whether the Paging is used for the data plane. For example, a value of 0 represents a normal paging message, and a value of 1 represents a data plane paging message, so that the terminal can distinguish whether the paging message received this time is the first paging message for the data plane or the second paging message for the second data plane.

[0102] (3) The LCID used in the first paging message is different from the LCID used in the second paging message;

[0103] The network side can set different LCIDs for different paging messages. For example, the newly added LCID1 represents a normal paging message, and LCID2 represents a paging message used for the data plane.

[0104] (4) The time domain resources of the first search space configured for the first paging message are different from the time domain resources of the second search space configured for the second paging message;

[0105] A dedicated search space is set for data plane paging to distinguish data plane paging from existing paging in the time domain.

[0106] (5) The frequency domain resources of the first search space configured for the first paging message are different from the frequency domain resources of the second search space configured for the second paging message;

[0107] A dedicated search space is set for data plane paging, thereby distinguishing data plane paging from existing paging in the frequency domain.

[0108] (6) The first channel for transmitting the first paging message is different from the second channel for transmitting the second paging message.

[0109] A new transport channel is defined for data plane Paging. The differences between this transport channel and the existing PCH include but are not limited to the following aspects:

[0110] (a) Time domain resources;

[0111] (b) frequency domain resources;

[0112] (c) multiplexing method;

[0113] (d)RNTI.

[0114] In one possible implementation, the preset strategy includes one or more of the following:

[0115] (1) When the processor usage of the terminal is higher than or equal to the first threshold, the terminal does not respond to the first paging message;

[0116] (2) When the battery level of the terminal is lower than or equal to the second threshold, the terminal does not respond to the first paging message.

[0117] In one possible implementation, the method further includes:

[0118] When the terminal receives the first paging message and the second paging message from the network side device, the terminal sends the first message to the network side device;

[0119] The first message is a message sent by the terminal during a random access process, and the second information field in the first message is used to instruct the terminal to respond to the first paging message or the second paging message.

[0120] In an embodiment of the present application, considering that the network side device can send both a first paging message and a second paging message to the terminal, the terminal performs random access after responding to the paging, and indicates through the message in the random access process whether the terminal responds to the first paging message or the second paging message, or both.

[0121] When the UE receives both normal paging and data plane paging sent by the network, it can decide to respond to both or only respond to one of them according to priority, depending on the UE status and policy. Because this may affect the settings of rrcSetup or rrcResume, for the 4-step random access scenario, consider further subdividing mt-Access in the cause of MSG3, such as mt-AccessNormal, mt-AccessDP, and mt-AccessBoth, which respectively represent normal paging services and data plane paging services, and can respond to normal paging and data plane paging at the same time; for the 2-step random access scenario, consider setting information in MSGA to represent normal paging services, data plane paging services, or to respond to normal paging and data plane paging at the same time.

[0122] The technical solution of this application is described below with reference to specific embodiments:

[0123] Example 1: Identifying data plane paging through different Paging messages;

[0124] The corresponding program instructions can be as follows:

[0125] When the network side initiates paging due to data plane services, it uses a pagingDP message that is independent of normal paging. The parameters of the pagingDP message can be reused with the existing paging message or newly defined.

[0126] After receiving the pagingDP message, a UE that does not support the data plane may directly discard the message; a UE that supports the data plane may also not respond to the paging message in the following situations:

[0127] 1. The CPU usage reaches the upper limit of the specified threshold;

[0128] 2. The power level reaches the lower limit of the specified threshold.

[0129] Example 2: Identifying data plane paging through short message;

[0130] When the network side performs data plane paging, in the Short Message field of the DCI corresponding to the Paging message, one bit is used to indicate whether the Paging message is used for data plane paging. A value of 0 indicates a normal paging message, and a value of 1 indicates a data plane paging message.

[0131] When a UE receives a DCI indicating data plane paging according to the UE policy after meeting the following conditions, it may not receive or process the PDSCH data indicated by the DCI:

[0132] 1. The CPU usage reaches the upper limit of the specified threshold;

[0133] 2. The power level reaches the lower limit of the specified threshold.

[0134] In addition, when a UE that does not support the data plane receives a DCI indicating data plane paging, it may not receive or process the PDSCH data indicated by the DCI.

[0135] Example 3: Identifying data plane paging through LCID;

[0136] The network side can set different LCIDs for different paging messages. For example, the newly added LCID1 represents a normal paging message, and LCID2 represents a paging message used for the data plane.

[0137] After the UE successfully decodes the PCH received content, it demultiplexes the Media Access Control (MAC) Protocol Data Unit (PDU).

[0138] When a UE that does not support the data plane parses LCID1, it delivers the corresponding MAC sub PDU to the upper layer; when it parses LCID2, it discards the corresponding MAC sub PDU message;

[0139] When a UE that supports the data plane resolves to LCID1, it delivers the corresponding MAC sub PDU to the upper layer. When it resolves to LCID2, it can directly discard the corresponding MAC sub PDU in the following situations, or it can deliver it to the upper layer, which decides whether to discard it according to the policy. Otherwise, it needs to be delivered to the upper layer for processing:

[0140] 1. The CPU usage reaches the upper limit of the specified threshold;

[0141] 2. The power level reaches the lower limit of the specified threshold.

[0142] In this case, the message used for data plane paging is not limited to Paging of the Radio Resource Control (RRC) protocol layer, but may also be a MAC Control Element (CE).

[0143] Example 4: Identifying data plane paging through time domain resources;
