[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on December 11, 2023, with application number: 202311700421.0, and named "Packet Data Network PDN Connection Control Method, Device, Electronic Device and Medium", the entire content of which is incorporated by reference into this application. Technical Field

[0003] The present application belongs to the field of communication technology, and specifically relates to a PDN connection control method, device, electronic device and medium. Background Art

[0004] Currently, when a user equipment (UE)'s data network is shut down, the data connection between the UE's application processor (AP) and modem is disconnected. However, the UE's PDN connection remains, retaining the Internet Protocol (IP) address assigned to the UE by the network device. In this case, the network device can still locate the UE via the IP address and send paging messages to the UE. However, because the data connection between the UE's AP and modem is disconnected, the UE cannot process received paging messages via the modem and, as a result, does not send acknowledgments of the paging messages to the network device. Consequently, the network device continues to send paging messages to the UE. Because the UE needs to monitor or receive paging messages from the network device, the UE cannot enter a sleep state, increasing the UE's power consumption. Summary of the Invention

[0005] The purpose of the embodiments of the present application is to provide a PDN connection control method, device, electronic device and medium, which can save UE power.

[0007] In the second aspect, an embodiment of the present application provides a PDN connection control device, which includes: an execution module; the execution module 301 is used to: when the data network of the UE is turned off, if a first paging message is received, the first value is increased by 1, and the first paging message is a paging message of the data service type, and the time interval between the reception time of the first paging message and the reception time of the previous data service type paging message is less than a preset duration, and the above-mentioned first value is the number of paging messages of the data service type; when the above-mentioned first value is greater than or equal to the first threshold, the first PDN connection is disconnected, and the first PDN connection is the connection between the UE and the PDN providing data services.

Through this method, when the data network of the UE is turned off, the UE can accumulate the number of paging messages of the data service type, and disconnect the PDN connection of the data service when the accumulated number is greater than or equal to the first threshold, so that after the data network of the UE is disconnected, the PDN connection of the data service can be disconnected when the UE frequently receives a large number of paging messages of the data service type, thereby avoiding the UE from continuing to monitor and receive paging messages after the data network is disconnected, so that the UE can enter a dormant state, thereby saving the power of the UE.

Similarly, "at least two" means two or more, and its meaning is similar to "at least one".

[0022] The following is an explanation of the proper nouns / terms involved in the embodiments of this application.

[0023] 1. Packet Data Network (PDN)

[0024] In the Evolved Packet System (EPS) system, PDN refers to an external data network (relative to LTE operators), such as the Internet, an enterprise private network, etc.

[0025] PDN can be divided into internal PDN and external PDN. Internal PDN is the packet data network in the EPS system, which is the network communication between EPS system entities (such as mobility management entities); while external PDN is the packet data network outside the EPS system, such as the Internet of Things (IoT) and VoLTE services.

[0026] 2. Modem

[0027] A modem is a piece of computer hardware that converts digital signals from electronic devices into analog signals. It converts data to be transmitted into radio frequency signals, converts radio frequency signals into data to be processed, handles signaling between the access stratum (AS) and non-access stratum (NAS), and interfaces with the application processor (AP).

[0028] 3. Application Processor

[0029] An application processor (AP) is a very large-scale integrated circuit (VLSI) that extends the power consumption of a low-power CPU with expanded audio and video capabilities and dedicated interfaces. The AP is responsible for processing applications on electronic devices, including multimedia, games, and web pages.

[0030] In related technologies, when the UE's data network is shut down, the data connection between the UE's AP and Modem will also be disconnected, while the PDN connection between the UE and the PDN will still be retained. In this case, the IP address assigned to the UE by the network device will still be retained, that is, the network device can still find the UE through the UE's IP address and send a paging message to the UE. After the UE monitors the physical downlink control channel (PDCCH) carrying the paging message indication at the paging moment, it receives the paging message from the corresponding physical downlink shared channel (PDSCH) to obtain the purpose of this paging. Since the data connection between the UE's AP and Modem has been disconnected after the data network is shut down, the data-related paging message received by the UE cannot be sent to the AP for processing, and thus no confirmation information for the data-related paging message will be sent to the network device, causing the network device to continue to send data-related paging messages to the UE. On the one hand, the UE needs to frequently monitor and receive paging messages, resulting in the UE being unable to enter the sleep state, thereby increasing the power consumption of the UE; on the other hand, the UE can still receive paging messages through the air interface, resulting in traffic consumption of the UE, which in turn causes abnormal traffic consumption of the EU.

[0031] In an embodiment of the present application, after the data network of the UE is turned off, when the UE receives a paging message sent by the network device and the time interval between the receiving time of the paging message and the receiving time of the previous paging message of the paging message is less than a preset time length, the UE adds 1 to the number of paging messages of the data service type, and disconnects the PND connection of the data service when the number of paging messages is greater than or equal to the first threshold. In this way, after the UE's PDN connection is disconnected, the UE can disconnect the PDN connection with the PDN providing the data service when it determines that a large number of paging messages are frequently received within a certain time period, thereby avoiding the network device from continuing to frequently send a large number of paging messages to the UE. On the one hand, it avoids the UE from frequently monitoring paging messages after the data network is disconnected, so that the UE can enter a sleep state, thereby saving the UE's power; on the other hand, it eliminates the need for the UE to frequently receive paging messages at the air interface, thereby reducing the UE's traffic consumption.

[0032] It should be noted that the above-mentioned paging message is a data-related paging message, that is, a data service type paging message.

[0033] The PDN connection control method provided in the embodiments of the present application may be executed by an electronic device or at least one of a functional module and an entity module in the electronic device that can implement the PDN connection control method. The specific execution subject may be determined based on actual usage requirements and is not limited by the embodiments of the present invention. The following example illustrates the PDN connection control method provided in the embodiments of the present application by taking the execution of the PDN connection control method by a UE as an example.

[0034] The following describes in detail the PDN connection control method provided in the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0035] FIG1 is a flow chart of a PDN connection control method provided in an embodiment of the present application. As shown in FIG1 , the PDN connection control method may include the following steps S201 and S202:

[0036] Step S201: When a data network of a user equipment UE is closed, if the UE receives a first paging message, the first value is increased by 1.

[0037] Among them, the above-mentioned first paging message is a paging message of data service type, and the time interval between the reception time of the first paging message and the reception time of the previous data service type paging message is less than the preset duration, and the above-mentioned first value is the number of paging messages of data service type.

[0038] In some embodiments of the present application, the data network refers to a network connected to a mobile device, such as a mobile phone, computer, or other portable electronic device. When the data flow function of the electronic device is turned on, the Internet access function, i.e., Internet access, can be achieved through the data network.

[0039] Exemplarily, the above-mentioned data network can be a data network of mobile communication technologies such as GPRS (General Packet Radio Service), EDGE (Enhanced Data rate for GSM Evolution), third-generation mobile communication technology, HSDPA (High Speed ​​Downlink Packet Access), LTE (Long Term Evolution), NR (New Radio, NR) or 6G.

[0040] In some embodiments of the present application, the data service type paging message may be a data service-related paging message. For example, the data service may be an Internet access service.

[0041] For example, according to different paging purposes, paging messages can be divided into data service related paging, call related paging and short messaging service (SMS) related paging.

[0042] In some embodiments of the present application, after the UE receives a paging message sent by the network side device, it can determine the type of the paging message, and when the paging message is a paging message of a data service type, determine whether the paging message is received within a preset time length after receiving the previous paging message. If so, the number of paging messages of the data service type (i.e., the first value) is increased by 1.

[0043] In some embodiments of the present application, the above-mentioned preset time length can be 20s, 30s or 40s, etc. The preset time length can be set according to actual needs, and the embodiments of the present application are not limited to this.

[0044] In some embodiments of the present application, after the data network of the UE is shut down, the UE may accumulate the number of received paging messages that meet an accumulation condition to obtain the number of paging messages of the data service type (i.e., the first value). Exemplarily, the accumulation condition may be that the paging message is a paging message of the data service type and the interval between the reception time of the paging message and the previous paging message of the data service type is less than a preset duration.

[0045] For example, after receiving paging message 1 related to data services, the UE adds 1 to the number of paging messages received related to data services. After receiving paging message 2 related to data services within 30 seconds after receiving paging message 1, the UE adds 1 to the number of paging messages received related to data services. After receiving paging message 3 related to data services within 30 seconds after receiving paging message 2, the UE continues to add 1 to the number of paging messages received related to data services. At this time, the number of paging messages related to data services is 3.

[0046] In an embodiment of the present application, when the time interval between the reception moments of two adjacent data service-related paging messages is less than a preset time length (for example, 30s), the UE accumulates the number of data service-related paging messages, so that the number can be accumulated when the frequency of receiving data service-related paging messages is high, and the accumulated number is subsequently compared with the upper limit value of the reception number (i.e., the first threshold value), so that the PDN connection can be triggered to be disconnected when the frequency of receiving data service-related paging messages is high and the number is large, while the PDN connection is still retained when the frequency of receiving data service-related paging messages is low, thereby avoiding the disconnection of the PDN connection when the frequency of receiving data service-related paging messages is low, resulting in a certain amount of time required to re-establish the PDN connection when the data network needs to be reused later, thereby balancing the power consumption and performance of the UE.

[0047] Step S202: When the first value is greater than or equal to the first threshold, the UE disconnects the first PDN connection.

[0048] The first PDN connection may be a connection between the UE and a PDN providing data services.

[0049] In some embodiments of the present application, a UE can typically establish PDN connections with two PDNs: one is an IMS (IP Multimedia Subsystem) PDN, and the other is an Internet PDN. The IMS PDN is responsible for services related to phone calls or text messages. The Internet PDN is responsible for services related to data services such as Internet access. For example, the first PDN connection can be a PDN connection with the Internet PDN.

[0050] It should be noted that IP stands for Internet Protocol.

[0051] It should be noted that after the UE's data network is disconnected, data service-related paging cannot be processed by the AP, while call or SMS-related paging messages can still be processed by the AP. Therefore, IMS PDN-related paging needs to be excluded and not used as a trigger for PDN connection disconnection.

[0052] In some embodiments of the present application, the first threshold is an upper limit on the number of paging messages of the data service type. For example, the first threshold can be 3, 5, or 10, etc. The first threshold can be set according to actual needs and is not limited in the embodiments of the present application.

[0053] Exemplarily, in combination with the above embodiments, taking the first threshold of 5 as an example, after receiving paging message 1 related to the data service, the UE adds 1 to the number of received paging messages related to the data service. After receiving paging message 2 related to the data service within 30 seconds after receiving paging message 1, the UE adds 1 to the number of received paging messages related to the data service. After receiving paging message 3 related to the data service within 30 seconds after receiving paging message 2, the UE continues to add 1 to the number of received paging messages related to the data service. At this time, the number of paging messages related to the data service is 3. And so on. When the UE accumulates the number of paging messages related to the data service to be 5, when the number of paging messages related to the data service (i.e., the first value) is equal to 5, the UE disconnects the connection with the PDN providing the data service.

[0054] In some embodiments of the present application, when the UE receives the first paging message, it adds 1 to the first value and starts a paging observation timer, where the paging observation timer is used to count with the above preset duration as the timing period.

[0055] For example, if the UE receives a paging message of another data service type within a preset time period after receiving a paging message related to a data service, the number of paging messages of the data service type is increased by 1, and the above-mentioned paging observation timer is restarted to restart the timing with the above-mentioned preset time period as the timing period through the paging observation timer.

[0056] It should be noted that each time the UE receives a paging message, if it is a paging message related to data services, the paging observation timer will be started and the number of paging messages related to data services will be increased by 1. During the operation of the paging observation timer, if the UE receives a paging message related to data services again, the number of paging messages related to data services will continue to be increased by 1, and the paging observation timer will be restarted to start timing again. When the number of paging messages related to data services reaches the first threshold, the internet PDN will be disconnected.

[0057] The following embodiment takes the first threshold value of 4 as an example to illustrate the PDN connection control method provided in the embodiment of the present application.

[0058] Exemplarily, when the data network of the UE is closed, the number of paging messages related to the data service of the UE (i.e., the first value) is 0. After receiving the paging message 1 related to the data service, the UE adds 1 to the number of paging messages received of the data service type and starts counting from the start of the paging observation timer with a timing duration of 30s. After the UE receives the paging message 2 of the data service type during the operation of the paging observation timer (i.e., within 30s), the UE adds 1 to the number of paging messages received of the data service type and restarts the paging observation timer with a timing duration of 30s. After the UE receives the paging message 3 of the data service type during the operation of the paging observation timer, the UE adds 1 to the number of paging messages received of the data service type and restarts the paging observation timer with a timing duration of 30s. After the UE receives the paging message 4 of the data service type during the operation of the paging observation timer, the UE adds 1 to the number of paging messages received of the data service type. In this case, the UE determines that the number of paging messages of the data service type is 4, which has reached the upper limit value, and then disconnects the PDN connection related to the data service.

[0059] In this way, when the user turns off the UE's data network, each time the UE receives a paging message related to a data service, the number of received paging messages related to the data service can be increased by 1, and a paging observation timer can be started to count with a preset duration as the timing period. When the number of paging messages related to the data service reaches a first threshold, it is considered that the current spam paging standard is met, and the internet PDN is actively disconnected, so that the IP address allocated to the UE by the network side device is reclaimed, and the UE will not continue to be paged, so that the UE does not need to frequently receive useless paging messages, thereby achieving the purpose of saving power and traffic.

[0060] The PDN connection control method provided in the embodiment of the present application is that after the data network of the UE is turned off, if the UE receives a paging message sent by the network device, and the time interval between the reception time of the paging message and the reception time of the previous paging message of the paging message is less than a preset time length, the number of paging messages of the data service type (i.e., the first value) is increased by 1, and when the number of paging messages is greater than or equal to the first threshold, the UE disconnects from the PDN providing the data service. Through this method, when the data network of the UE is turned off, the UE can accumulate the number of paging messages of the data service type, and disconnect the PDN connection of the data service when the accumulated number is greater than or equal to the first threshold, so that after the data network of the UE is disconnected, the PDN connection of the data service can be disconnected when the UE frequently receives a large number of paging messages of the data service type, thereby avoiding the UE from continuing to monitor and receive paging messages after the data network is disconnected, so that the UE can enter a dormant state, thereby saving the power of the UE.

[0061] In some embodiments of the present application, when the data network of the user equipment UE is shut down in the above step S201, the PDN connection control method provided in the embodiment of the present application may include the following step S203:

[0062] Step S203: If the UE receives the second paging message, the first value is set to zero.

[0063] The second paging message is a non-data service type paging message.

[0064] Exemplarily, if the UE receives a paging message of a non-data service type within a preset duration after receiving a paging message of a service data type, the UE clears the number of paging messages of the data service type, that is, sets the first value to zero.

[0065] In some embodiments, the UE can start a paging observation timer with a preset duration as the timing period. During the operation of the paging observation timer, if the UE receives a paging message of a non-data service type (i.e., a second paging message), the UE will clear the number of paging messages of the data service type to zero.

[0066] Exemplarily, in combination with the above example, when the data network of the UE is turned off, the number of paging messages related to the data service of the UE is 0. After receiving the paging message A related to the data service, the UE adds 1 to the number of paging messages of the data service type, and starts the paging observation timer to count with a timing duration of 30s. After the UE receives the paging message B of the data service type during the operation of the paging observation timer (i.e. within 30s), the UE adds 1 to the number of paging messages of the data service type, and restarts the paging observation timer to count with a timing duration of 30s. After the UE receives the paging message C of the telephone service type (i.e. non-data service type) during the operation of the paging observation timer, the UE clears the previously accumulated number of paging messages of the data service type, that is, resets the previously accumulated 2 to 0.

[0067] Exemplarily, after the UE sets the number of paging messages of the data service type to zero, the UE may start accumulating the number of paging messages of the data service type from zero after receiving the paging message of the data service type again.

[0068] In this way, when the user turns off the UE's data network, each time the UE receives a data service-related paging message, it can add 1 to the number of data service-related paging messages and start a paging observation timer to count with a preset duration as the timing period. During the timer counting period, if the number of data service-related paging messages does not reach the first threshold and a non-data service-related paging message (such as a telephone service-related paging message) is received, the previously accumulated number of data service-related paging messages is cleared to record the number of data service-related paging messages from zero again. In this way, when the number of data service-related paging messages received by the UE is small and a non-data service-related paging message is received during the period, the counted data service-related paging messages can be cleared, thereby achieving the goal of disconnecting the PDN connection only after a certain number of data service-related paging messages are received continuously, thereby avoiding frequent disconnection of the PDN connection.

[0069] In some embodiments, the UE may start a paging observation timer with a preset duration as the timing period. During the operation of the paging observation timer, if the UE does not receive a paging message of the data service type again, the UE will clear the number of paging messages of the data service type to zero.

[0070] Exemplarily, in combination with the above example, when the UE's data network is turned off, the number of data service-related paging messages of the UE is 0. After receiving the data service-related paging message D, the UE adds 1 to the number of data service type paging messages and restarts the paging observation timer with a timing duration of 30s. After the UE receives the data service type paging message E during the operation of the paging observation timer (i.e. within 30s), the UE adds 1 to the number of received data service type paging messages and restarts the paging observation timer with a timing duration of 30s. If the UE does not receive the data service-related paging message again during the operation of the paging observation timer (i.e. within 30s), the previously accumulated number of data service type paging messages is cleared, that is, the accumulated 2 are set to 0.

[0071] In this way, when the user turns off the UE's data network, each time the UE receives a data service-related paging message, the UE can add 1 to the number of data service-related paging messages received, and start a paging observation timer to count with a preset duration as the timing period. During the timer counting period, if the number of data service-related paging messages does not reach the first threshold and no data service-related paging message is received again, the previously accumulated number of data service-related paging messages is cleared to record the number of data service-related paging messages received from zero again. In this way, when the number of data service-related paging messages received by the UE is small and no data service-related paging message is received within a certain period of time, the counted data service-related paging messages can be cleared, thereby achieving the goal of disconnecting the PDN connection only after a certain number of data service-related paging messages are received continuously, thereby avoiding frequent disconnection of the PDN connection.

[0072] In some embodiments of the present application, as shown in FIG2 , if the first paging message is received in the above step S201, before adding 1 to the first value, the PDN connection control method provided by the embodiment of the present application may include the following step S204:

[0073] Step S204: If the UE receives the third paging message, it starts counting and records the first value as 1.

[0074] The third paging message is the first data service type paging message received after the data network is shut down.

[0075] In some embodiments, after the UE's data network is shut down, when the UE receives the first data service-related paging message, the UE starts to accumulate the number of data service type paging messages and records the initial number of data service type paging messages (i.e., the first value) as 1.

[0076] In some embodiments, after the UE receives the first data service-related paging message, it can start a paging observation timer and control the paging observation timer to start timing with a timing duration of 30 seconds. If another data service-related paging message is received within 30 seconds after the paging observation timer is started, the first value is increased by 1. If another data service-related paging message is not received within 30 seconds after the paging observation timer is started or a non-data service-related paging message is received, the first value is set to 0.

[0077] In this way, the UE determines whether to continue accumulating or setting the number of paging messages of the service data type by judging the time interval between the reception times of two adjacent data service type paging messages, thereby being able to disconnect the PDN connection when the paging messages of the data service type are received more frequently and the number of paging messages of the data service type is large, thereby saving the UE's power and avoiding frequent disconnection of the PDN connection.

[0078] In some embodiments of the present application, the PDN connection control method provided in the embodiment of the present application may further include the following step S205:

[0079] Step S205: When the running state of the UE satisfies the first preset condition, the UE clears the number of received paging messages of the data service type to zero.

[0080] The first precondition mentioned above includes any one of the following:

[0081] The UE enters flight mode;

[0082] Restart the UE;

[0083] The SIM card of the UE is removed;

[0084] The primary SIM card and secondary SIM card of the UE are swapped.

[0085] In some embodiments, when the data network is turned off and the UE receives a paging message related to a data service, the UE accumulates the number of paging messages of the data service type, and clears the number of paging messages of the data service type when it detects that its own operating status meets the first preset condition.

[0086] For example, in combination with the above example, when the UE's data network is turned off, assuming that the number of data service-related paging messages of the UE is 0, after receiving data service-related paging message 1, the UE adds 1 to the number of data service type paging messages, and after receiving data service-related paging message 2, continues to add 1 to the number of received data service type paging messages. At this time, the number of data service-related paging messages is 2. If the UE detects any of the following: entering flight mode, restarting, SIM card being pulled out, or swapping the primary SIM card and the secondary SIM card, the accumulated number of data service-related paging messages will be cleared.

[0087] It should be noted that when the UE enters flight mode, is restarted, the SIM card is removed, or the primary SIM card and the secondary SIM card are swapped, it can be considered that the UE has entered a new usage phase. Therefore, the number of paging messages related to data services previously counted can be reset to zero, and the number of paging messages related to data services can be re-counted from 0.

[0088] In this way, the UE can reset the number of paging messages of data service types when it enters flight mode, restarts, the SIM card is removed, or the primary SIM card and the secondary SIM card are swapped. This allows the UE to count the number of paging messages of data service types from zero when the data network is turned off during the next use, thereby not affecting the user's subsequent use of the UE.

[0089] In some embodiments of the present application, after the UE disconnects the first PDN connection in the above step S202, the PDN connection control method provided in the embodiment of the present application further includes the following step S206:

[0090] Step S206: When the second PDN connection of the UE is disconnected, the UE re-establishes the first PDN connection.

[0091] The second PDN connection may be a connection between the UE and a PDN providing an IP Multimedia Subsystem IMS service.

[0092] In some embodiments, the above-mentioned IMS service may include a voice service, a video service, or a short message service.

[0093] In some embodiments, the second PDN connection may be a connection with a PDN that provides a voice service, or the second PDN connection may be a PDN connection with a PDN that provides a short message service.

[0094] In some embodiments, the UE may re-establish the first PDN connection when the data network is reopened.

[0095] In this way, the UE can re-establish the first PDN connection when the second PDN connection is disconnected or the UE's data network is reopened, so that the network device can obtain the UE information and ensure the normal execution of the UE service.

[0096] The above-mentioned method embodiments, or various possible implementation methods in each method embodiment, can be executed separately, or, under the premise that there is no contradiction, can also be executed in combination with each other. The specific implementation can be determined according to actual usage requirements, and the embodiments of the present application do not limit this.

[0097] The PDN connection control method provided in the embodiment of the present application may be executed by a PDN connection control device. In the embodiment of the present application, the PDN connection control device performing PDN connection control is taken as an example to illustrate the PDN connection control device provided in the embodiment of the present application.

[0098] FIG3 is a schematic diagram of the structure of a PDN connection control device provided in an embodiment of the present application. As shown in FIG3 , the PDN connection control device 300 may include an execution module 301, which is configured to:

[0099] When the data network of the UE is turned off, if a first paging message is received, the first value is increased by 1. The first paging message is a paging message of the data service type, and the time interval between the reception time of the first paging message and the reception time of the previous data service type paging message is less than the preset duration. The above-mentioned first value is the number of paging messages of the data service type; when the above-mentioned first value is greater than or equal to the first threshold, the first PDN connection is disconnected. The first PDN connection is the connection between the UE and the PDN providing data services.

[0100] In some embodiments, the execution module is further configured to clear the first value to zero when the UE receives a second paging message, where the second paging message is a non-data service type paging message.

[0101] In some embodiments, the above-mentioned execution module is also used to start counting and record the first value as 1 if a third paging message is received before adding 1 to the first value. The above-mentioned third paging message is the first data service type paging message received after the data network is closed.

[0102] In some embodiments, the above-mentioned execution module is used to clear the number of received paging messages of the data service type to zero when the operating status of the UE meets the first preset condition; wherein the above-mentioned first preset condition includes any one of the following: the UE enters flight mode; the UE is restarted; the UE's user identity module SIM card is pulled out; the UE's primary SIM card and secondary SIM card are swapped.

[0103] In some embodiments, the execution module is further configured to re-establish the first PDN connection after the UE disconnects the first PDN connection and when the UE's second PDN connection is disconnected; wherein the second PDN connection is a connection between the UE and the PDN providing the IMS service.

[0104] The PDN connection control device provided in the embodiment of the present application, after the data network of the UE is turned off, if the UE receives a paging message sent by the network device, and the time interval between the reception time of the paging message and the reception time of the previous paging message of the paging message is less than a preset time length, then the number of paging messages of the data service type (i.e., the first value) is increased by 1, and when the number of paging messages is greater than or equal to the first threshold, the UE disconnects from the PDN providing the data service. Through this method, when the data network of the UE is turned off, the PDN connection control device can accumulate the number of paging messages of the data service type, and disconnect the PDN connection of the data service when the accumulated number is greater than or equal to the first threshold, so that after the data network of the UE is disconnected, the PDN connection of the data service can be disconnected when the UE frequently receives a large number of paging messages of the data service type, thereby preventing the UE from continuing to monitor and receive paging messages after the data network is disconnected, so that the UE can enter a dormant state, thereby saving the power of the UE.

Through this method, when the data network of the electronic device is turned off, the electronic device can accumulate the number of paging messages of the data service type, and disconnect the PDN connection of the data service when the accumulated number is greater than or equal to the first threshold, so that after the data network of the UE is disconnected, the PDN connection of the data service can be disconnected when the electronic device frequently receives a large number of paging messages of the data service type, thereby avoiding the electronic device from continuing to monitor and receive paging messages after the data network is disconnected, so that the electronic device can enter a dormant state, thereby saving the power of the electronic device.
