Some embodiments of the application are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Fig. 1 is a schematic diagram of a user equipment communication scenario provided in an embodiment of the present application.

Referring to fig. 1, the user equipment 200 is connected to a first application server 301 through a first cellular network access point 301 and to a second application server 402 through a second network access point 302.

It is understood that user device 200 includes, but is not limited to, a portable or mobile device, a cell phone, a tablet, a television, a personal digital assistant, a laptop device, a desktop, a handheld PC, a server, a network device, a graphics device, a video game device, a set-top box, a cellular telephone, a portable media player, a handheld device, a wearable device (e.g., display glasses or goggles, a head-mounted display, a watch, a head-mounted device, an arm band, jewelry, etc.), a virtual reality and/or augmented reality device, an internet-of-things device, an industrial control device, an in-vehicle infotainment device, a streaming media client device, an e-book reading device, a POS machine, or other electronic device capable of wireless and/or wired communication.

It is understood that the user equipment 200 may support one or more Subscriber Identity Module (SIM) cards. One SIM card for each cellular mobile communications network. For convenience of description, the SIM card and its evolution are collectively referred to as the SIM card in the embodiments of the present application. For example, the SIM card may be an identification card of a Global System For Mobile Communications (GSM) digital Mobile phone user, and is used For storing an identification code and a secret key of the user and supporting authentication of the GSM System to the user. For another example, the SIM card may be a Universal Subscriber Identity Module (USIM), which may also be referred to as an upgraded SIM card.

It can be understood that, when the user equipment 200 can support multiple SIM cards, the primary SIM card may be in Long Term Evolution (LTE) mode or 5G dependent network group (Non-standby, NSA) mode. The secondary SIM card may support a Global System For mobile communications (GSM) System, a Universal mobile telecommunications System (Universal mobile 1 telecommunications System, UMTS) System, a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) System, a Long Term Evolution (LTE) System, a Code Division Multiple Access (CDMA) System, a New System (New System, NS) System, a 5G Non-Standalone network group (Non-Standalone, NSA) System, a 5G Standalone network group (Standalone, SA) System, and the like.

It is understood that when user equipment 200 may support multiple SIM cards, then user equipment 200 may support dual card data concurrency functions or non-dual card data concurrency functions.

It is understood that the user equipment 200 can communicate with other devices by accessing the cellular mobile communication network through the first cellular network access point 2301. The user equipment 200 may also access the cellular mobile communication network through the second network access point 302 or communicate with other devices through wireless communication technology (Wi-Fi).

It will be appreciated that the server may send polling, long connection, and push messages to the application after establishing a connection with the application within the user device 200. Illustratively, long connections include User Datagram Protocol (UDP) connections, Transmission Control Protocol (TCP) connections, and the like.

It is understood that after the application in the user equipment 200 establishes the UDP-based connection with the server, since the UDP does not provide the online status of the user equipment, the server and the user equipment 200 usually use a periodic message to determine whether the user equipment 200 is online.

It is understood that, after the application in the user equipment 200 establishes the TCP connection with the server through the three-way handshake, as long as the connection is not closed (Finish, FIN) or Reset (Reset, RST), the user equipment 200 and the server may determine that both the opposite end is online. However, in practical applications, both the user device 200 and the server side send heartbeat packets to detect the connection status of the opposite side, and discover whether the opposite side is online.

Illustratively, as shown in fig. 1, a user device 200 includes a first Application (APP) 210 and a second Application 220. After the first application 210 in the user equipment 200 establishes a UDP or TCP connection with the first application server 401 through the first cellular network access point 301, the user equipment 200 is handed over from the first cellular mobile communication network to the other network. At this time, after the user equipment 200 establishes a connection with the first cellular mobile communication Network, at least one Public Data Network (PDN) connection is reserved, and the PDN connection is not actively disconnected after switching to another Network. Although the connection between the user equipment 200 side and the first cellular mobile communication network has been disconnected on the access network side, at least one PDN connection remains between the user equipment 200 and the first cellular mobile communication network, i.e. the first cellular mobile communication network of the user equipment 200 is in a suspended state at the core network instead of a switched-off state. Thus, the user equipment 200 is still online to the core network. In some scenarios, if the user equipment is handed over from the first cellular mobile communication network to another network, such as a Wifi network or a second cellular mobile network, the core network of the first cellular network also considers the user equipment 200 to be online at this time. At this time, the application server may think that the ue is still connected through the first cellular network, and still send the data packet to the ue through the first cellular network. These messages may wake up the primary card corresponding to the first cellular mobile communication network, and affect the internet performance of other cards, such as the secondary card. Specifically, if the ue 200 supports the dual-card data concurrency function, because the dual-card data concurrency function is usually implemented by a Time Division Multiplexing (TDM) function, re-waking up the main card corresponding to the first cellular mobile communication network may affect bandwidths of other cellular mobile networks and increase power consumption of the ue 200. Specifically, if the ue 200 does not support the dual-card data concurrency function, re-waking up the main card corresponding to the first cellular mobile communication network may occupy Radio Frequency (RF) resources of the ue 200, and affect performance such as bandwidth of other cellular mobile networks.

For another example, if the user equipment 200 has switched from the first cellular mobile communication network to the Wi-Fi network, since the internet PDN connection of the first cellular mobile communication network is not disconnected, the first application server 301 cannot know that the user equipment 200 has switched from the first cellular mobile communication network to the Wi-Fi network before the first application 210 sends a packet to the first application server 401 through the Wi-Fi network. Therefore, the first application server 401 may still use the first cellular mobile communication network for packet transmission when transmitting the packet to the first application 210 in the user equipment 200. And each time the main card corresponding to the first cellular mobile communication network is awakened, Radio Resource Control (RRC) layer connection is established, which improves power consumption and traffic consumption of the ue 200.

It can be understood that, when the second application 220 in the user equipment 200 establishes a connection with the second application server 402 through the second network access point 302, the connection information received by the second application server 402 is from the second network access point 302, and therefore, the second application server 402 does not wake up the corresponding main card of the first cellular mobile communication network when sending a message.

It is understood that the running state of the application in the user equipment 200 can be divided into foreground application, background application, resident application, and the like. It can be understood that, since the foreground application interacts with the server more frequently, the latest parameters such as the latest Internet Protocol (IP) are attached when the application and the server receive and transmit data in the interaction process, and therefore, the host card corresponding to the first cellular mobile communication network is not easily woken up. And because the interaction frequency of the applications such as the background application and the resident application with the server is low, when the server side does not acquire parameters such as an IP (internet protocol) which is not updated by the background application and the resident application, the message is sent to the first cellular mobile communication network, and further the main card corresponding to the first cellular mobile communication network is awakened.

Fig. 2 is a block diagram of a user device 200.

Referring to fig. 2, the ue 200 further includes an Application Processor (AP) 230, a baseband (Modem) Processor 240, a host SIM card 250, and a Wi-Fi module 260.

It can be understood that the application processor 230 is called a Multimedia Application Processor (MAP) and refers to a very large scale integrated circuit that extends audio and video functions and a dedicated interface on the basis of a low power consumption central processing unit CPU. The application processor 230 can run a complex operating system such as Linux kernel (android kernel), Harmony kernel (Harmony kernel), Windows kernel, etc., and the multimedia type processor refers to a processor that processes more than two media, such as image, sound, video, and 3D graphics. A single multimedia type processor refers to a processor that processes one medium, generally only for processing images or sound.

It can be understood that the baseband Processor 240 is an important component in the system chip, and is equivalent to a protocol Processor, and is responsible for processing and storing data, and mainly includes units such as a Digital Signal Processor (DSP), a microcontroller (Micro Controller Unit, MCU), and a memory (e.g., flash memory), and its corresponding main functions are responsible for baseband encoding or decoding, voice encoding and voice encoding, and so on. Currently, the baseband processor 240 not only supports multiple communication standards, but also provides multimedia functions and provides related communication interfaces for multimedia displays, image sensors, and audio devices.

It is understood that in practical applications, the software that the application processor 230 typically supports includes an operating system, a user interface, an application program, and the like. The Baseband processor 240 may be regarded as a wireless Modem module, which is responsible for coordinating and controlling communications between the Baseband and the base station and the application processor 230, and supports operating software including Baseband Modem (Baseband Modem) communication control software, etc.

It is understood that the application processor 230 and the baseband processor 240 support mutual communication by using a preset Interface technology, which may be set by the system in a self-defined manner, for example, the Interface technology includes but is not limited to Serial Peripheral Interface (SPI), Universal Asynchronous Receiver/Transmitter (UART), Universal Serial Bus (USB), General Purpose Input/Output control line (GPIO), and the like. Specifically, the application processor 230 and the baseband processor 240 may implement communication transmission between each other in a message format through a control command, so as to complete functions of a call, a short message, mobile internet, and the like. The control command may include a conventional at (attention) command, a Mobile Broadband Interface (MBIM) command, or other protocol commands supporting the mutual transmission between the application processor 230 and the baseband processor 240.

It is understood that the application processor 230 may be regarded as one processor core, the baseband processor 240 may be regarded as another processor core, and the communication between the two cores follows a specific inter-core communication protocol, which is not limited by the embodiment of the present invention. It can be understood that, in the application processor 230, after the packet passes through a TCP protocol stack and an IP protocol stack of a core (also called a core state) through a socket interface of a source end of the TCP connection, a Task (Task, which may also be understood as a thread) used for inter-core communication in the application processor 230 and the baseband processor 240 respectively is used to transfer the packet to a GSM protocol stack, a UMTS protocol stack, a TD-SCDMA protocol stack, an LTE protocol stack, a CDMA protocol stack, an NR protocol stack, an NSA protocol stack, and an SA protocol stack (which may also be understood as a Task or a thread) in the Modem, and the protocol stack sends the packet out of the user equipment 200 through hardware in the baseband processor 240. The protocol stack is used for carrying one or more communication protocols of a data link layer and a physical layer, and is mainly used for communication protocols of various cellular networks, such as a GSM protocol, a UMTS protocol, a TD-SCDMA protocol, an LTE protocol, a CDMA protocol, an NR protocol, an NSA protocol, an SA protocol, and the like.

It is understood that the main SIM card 250 has the same functions and functions as the main SIM card described in fig. 1, and will not be described in detail herein.

It will be appreciated that Wi-Fi module 260 is used to wirelessly interconnect user device 201 with devices within a wireless local area network.

It is understood that when the user equipment 200 includes the application processor 230, the baseband processor 240, and the primary SIM card 250, the user equipment 200 may implement the attach function, PDN default bearer activation, IMS bearer establishment, IMS registration, and data service deactivation functions.

Fig. 3 is a block diagram of a user equipment 201 according to an embodiment of the present application.

Referring to fig. 3, in comparison with fig. 2, the user equipment 201 in fig. 3 further includes a secondary SIM card 270.

It is understood that the secondary SIM card 270 has the same functions and functions as the secondary SIM card described in fig. 1, and thus, will not be described again.

It is understood that, compared with the user equipment 200 in fig. 2, the user equipment 201 in fig. 3 can also implement the primary and secondary card switching and smart dual card switching functions.

It is understood that when the user equipment 201 supports the smart dual card switching function, the application processor 230 automatically controls the user equipment 201 to switch the network to the signal provided by the secondary SIM card 270 when detecting the signal degradation of the primary SIM card 250. The primary card and the secondary card in the smart dual card can be set according to the requirements of the user, and the application is not limited herein.

It should be understood that the hardware configuration shown in fig. 2 and 3 is only one example. The user equipment of embodiments of the present application may have more or fewer components than the user equipment shown in the figures, may combine two or more components, or may have a different configuration of components. The various components shown in the figures may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

Fig. 4 is a flowchart illustrating a communication management method according to an embodiment of the present application. By using the communication management method provided by the embodiment of the present application, it is possible to avoid that the network performance and power consumption of the user equipment 200 are affected due to the frequent wake-up of the SIM card corresponding to the first cellular mobile communication network.

Referring to fig. 4, the communication management method includes:

s100: and judging whether a trigger event occurs.

Wherein, when the triggering event is judged to occur, S200 is executed. When it is determined that the trigger event has not occurred, S100 is continuously performed.

It is to be understood that whether a trigger event occurs may be determined by the application processor 230 in the user equipment 200. When a triggering event occurs, it indicates that the network connection of the user equipment 200 is handed over from the first cellular mobile communication network to the other network. For example, the triggering event includes turning off the data switch, switching to Wi-Fi, switching the primary card to the secondary card in the dual smart card mode, switching the secondary card to the primary card in the dual smart card mode, and the like when the user equipment 200 communicates using the first cellular mobile communication network.

S200: it is determined whether an IP Multimedia Subsystem (IMS) is active. Wherein, when the IMS is determined to be in the active state, S300 is performed. And returning to S100 when judging that the triggering event does not occur.

S300: the type of the triggering event is obtained.

S400: and setting a back-off timer according to the type of the trigger event. It will be appreciated that different back-off timing durations may be set depending on the type of triggering event.

It will be appreciated that the back-off timing duration may be set to a time within 0-30 minutes in general. It can be understood that since the frequency of sending messages by the server is obviously reduced after 30 minutes, setting the back-off timing duration within 30 minutes can effectively reduce the frequency of the first cellular mobile communication network being awakened.

It will be appreciated that the types of triggering events include when the user equipment 200 is communicating using the first cellular mobile communications network: turning off the data switch, switching to Wi-Fi, switching the main card to the auxiliary card or switching the auxiliary card to the main card in the smart dual-card mode, and the like.

For example, when the triggering event is to turn off the data switch, it may be considered that the data switch of the user equipment 200 is not turned on in a short time, and therefore, the first backoff fixed length may be set, and the first backoff timing duration may be set to a longer time, for example, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, and the like, which is not limited herein.

For example, when the trigger event is switching to Wi-Fi, it may be considered that the user equipment 200 does not switch to the Wi-Fi network for a short time, and thus the second back-off timing may be set. The duration setting logic of the second back-off timing may be similar to the duration of the first back-off timing, and the application is not limited herein.

For example, when the triggering event is switching the main card, it may be considered that the user equipment 200 does not switch back to the main card (i.e. the first cellular network) in a short time, and therefore, the third back-off timing may be set, and the duration setting logic of the third back-off timing may be similar to the duration of the first back-off timing or the duration of the second back-off timing, which is not limited herein.

For example, when the secondary card is switched from the primary card to the secondary card, the remaining traffic of the secondary card may be detected, if the remaining traffic of the secondary card is lower than a threshold, it may be determined that the user equipment 200 may be switched back to the primary card (i.e., the first cellular network) in a short time, and the third back-off timing may be set to a shorter time duration, for example, 1 minute, 2 minutes, 3 minutes, 5 minutes, and the like, which is not limited herein.

For example, when the triggering event is the smart dual card switching to the secondary card, since the smart dual card is switched frequently, it may be considered that the user equipment 200 has a situation of switching the cellular mobile communication network in a short time, and therefore, the fourth back-off timing duration may be set, and the fourth back-off timing duration is set to be short, for example, 1 minute, 2 minutes, 3 minutes, 5 minutes, and the like, which is not limited herein.

For example, when the triggering event is the smart dual card switching to the master card, since the smart dual card is frequently switched, it may be considered that there is a possibility of switching in a short time in the cellular mobile network of the user equipment 200, and therefore, the fifth back-off timing duration may be set, and the setting logic of the fifth back-off timing duration may be similar to the setting of the fourth back-off timing duration, which is not limited herein.

S500: deactivating the internet PDN.

It is to be appreciated that deactivating the internet PDN operation is performed after setting the back-off timer according to the type of triggering event.

Referring to fig. 11, fig. 11 is an interaction diagram of a ue and a core network according to an embodiment of the present application.

Referring to fig. 11, deactivating the internet PDN includes:

s510: and sending a PDN connection removal request.

It is understood that the ue 200 sends a PDN disconnection REQUEST (PDN DISCONNECT REQUEST) to the core network 300 to REQUEST to connect to a PDN, and all global Paging System (EPS) bearer contexts established with the PDN, including the default EPS bearer context, are released.

S520: requesting deactivation of the EPS bearer context.

It is understood that the core network 300 sends a REQUEST to deactivate the EPS BEARER CONTEXT to the user equipment 200 (DEACTIVATE EPS BEARER CONTEXT REQUEST) to indicate that the core network 300 side accepts the PDN reconnection REQUEST sent by the user equipment 200 and performs the deactivation operation.

S530: accepting to deactivate an EPS bearer context.

It may be understood that the user equipment 200 sends an ACCEPT to deactivate EPS BEARER CONTEXT (DEACTIVATE EPS BEARER CONTEXT ACCEPT) to the core network 300 to release all EPS BEARER CONTEXTs between this PDN. After the ue 200 sends the context accepting deactivation of the EPS bearer to the core network 300, the ue 200 successfully performs the cancellation on the core network 300 side, and even if the server sends the message to the core network 300 side again, the core network 300 does not send the message to the ue 200.

S600: a back-off timer is started.

It is to be understood that, after the deactivation of the internet PDN operation is completed, the user equipment 200 starts a Backoff Timer (Backoff Timer), and sets a duration of the Backoff Timer according to the set Backoff-timing duration.

It can be understood that starting the back-off timer after the internet PDN connection is deactivated can improve the accuracy of timing, and avoid reactivating the internet PDN connection after the failure of deactivating the internet PDN connection.

It is understood that, in some embodiments, the execution sequence between step S600 and step S500 is not limited. It can be appreciated that setting the start back-off timer to be performed in parallel with or in advance of sending the PDN reconnection request can improve the operational efficiency of the communication management method.

It is understood that after the back-off timer is started, the application processor 230 continuously detects the state of the user equipment 200, and if it detects that the triggering event is over, such as the data switch is turned on, the Wi-Fi is switched back to the cellular mobile network, the secondary card is switched back to the primary card in the dual-card mode, or the primary card is switched back to the secondary card, and the back-off timer is not timed out, the timing function of the back-off timer is terminated, and step S700 is executed to reactivate the internet PDN. It can be appreciated that the reactivation of the internet PDN after detection of the end of the triggering event can increase the speed at which the user equipment 200 reconnects to the original cellular mobile communication network, avoiding a situation in which the user equipment 200 cannot connect to the internet quickly after switching back to the original cellular mobile communication network.

It is understood that, in some embodiments, the backoff timer may not be set, and the application processor 230 continuously monitors whether the triggering event is ended after the internet PDN deactivation procedure is ended, and executes step S700 to reactivate the internet PDN after the triggering event is monitored to be ended. It can be understood that canceling the back-off timer and continuously monitoring whether the trigger event is over can further reduce the number of times the original cellular mobile communication network of the user equipment 200 is woken up, and reduce the power consumption of the user equipment 200.

S700: and reactivating the Internet PDN.

It is to be understood that the internet PDN is reactivated after the back-off timer expires to reestablish the connection between the user equipment 200 and the core network 300.

It can be understood that the user equipment 200 sets the duration of the back-off timer according to different trigger events, and reactivates the internet PDN after the back-off timer expires, so as to improve the connection speed after the user restarts the application.

For example, referring to fig. 1, after the first application 210 in the ue 200 establishes a UDP or TCP connection with the first application server 401 through the first cellular network access point 301, the ue 200 switches from the first cellular mobile communication network to the Wi-Fi network, and at this time, if the first application server 401 sends a data packet to the first application 210, the data packet is still sent to the first cellular mobile communication network. After detecting that the trigger event is the switch from the first cellular mobile communication network to the Wi-Fi network, the user equipment 200 sets the duration of the back-off timer as a second back-off timing duration according to the type of the trigger event. The user equipment 200 performs deactivation of the first cellular mobile communication network and starts a back-off timer. After the back-off timer expires, the internet PDN is reactivated to reconnect the user equipment 200 to the first cellular mobile communication network.

It can be understood that, since the user equipment 200 still maintains the internet PDN after disconnecting from the first cellular mobile communication network, displaying that the user equipment 200 is still online on the core network 300 side may cause the first application server 401 to pull up the first cellular mobile communication network when issuing the data packet, which affects data transceiving and power consumption of the user equipment 200. By using the communication method provided by the embodiment of the application, the PDN connection can be deactivated, and the SIM card corresponding to the first cellular mobile communication network is prevented from being frequently awakened. Meanwhile, in order to improve the connection speed after the ue 200 reconnects to the first cellular mobile communication network, the communication method provided in this embodiment further provides a back-off timer, so as to set different back-off timing durations according to different trigger event types. After the back-off timer expires, the user equipment 200 is reconnected back to the first cellular mobile communication network, so that the user equipment 200 can quickly enable the first cellular mobile communication network.

It can be understood that the back-off timing duration can also be adjusted according to the usage habit of the user and other data of the chip.

For example, if the user equipment 200 detects that the trigger event is switched from the first cellular mobile communication network to the Wi-Fi network, and the current storage tag of the Wi-Fi network is a company or a home, it may be considered that the user equipment 200 is not switched back to the first cellular mobile communication network for a longer time, and therefore, the duration of the first back-off timer may be set to a longer time, for example, 30 minutes or longer, so as to reduce the trigger frequency of the communication management method, and thus reduce the power consumption of the user equipment 200.

For example, if the ue 200 detects that the trigger event is switched from the first cellular mobile communication network to the Wi-Fi network, and the GPS or beidou positioning chip detects that the ue 200 is in a moving state (i.e. the ue 200 does not turn off the Wi-Fi switch and accesses the Wi-Fi network that was accessed during moving), it may be determined that the ue 200 may switch back to the first cellular mobile network in a short time, and at this time, the second back-off timing duration may be set to a shorter time, or the internet PDN operation is not deactivated, so as to increase the speed of reconnecting the user back to the first cellular mobile communication network, and improve the user experience.

For example, if the user equipment 200 detects that the data switch is turned off by a trigger event, information such as the current signal strength, the current data traffic remaining in the SIM card package, and whether the flight mode is turned on may be further detected. For example, when it is detected that the current signal strength of the ue 200 is poor and the flight mode is turned off rapidly after being turned on, it may be considered that the ue 200 is restarting the network, and the ue 200 will re-establish the connection after going to connect to the first cellular mobile communication network, so the back-off timing duration does not need to be set.

For example, if the user equipment 200 detects a trigger event smart dual-card switching, the remaining flow rates of the packages of the primary SIM card 250 and the secondary SIM card 270 may be further obtained, and if the remaining flow rates of the packages of the current SIM card are low in the smart dual-card switching process, it may be considered that the user equipment 200 will switch back to the original SIM card within a short time. Therefore, the back-off timing duration can be set to a shorter time to improve the response speed of the user equipment 200 in switching back to the original SIM card.

S800: and ending the flow.

It can be understood that, when detecting that the triggering event of the user equipment 200 does not need to intervene to deactivate the PDN connection, the communication management method provided in the embodiment of the present application ends the monitoring procedure until detecting the triggering event again to determine whether intervention is needed again.

For example, after the application is converted into the background application, the server typically sends a message to the background application at 5 seconds, 1 minute, 5 minutes, and 10 minutes. When receiving each message, the user equipment 200 side needs to re-establish an RRC connection, and 11 seconds are required for re-establishing the RRC connection and completing the message reception each time. Taking the working voltage of the user equipment 200 as V and the working current as I as an example, the electricity consumption of 44S V I is consumed in receiving the four messages. I.e., a background application will generate 44S V I power usage. By using the communication management method provided by the embodiment of the application, the time of 12 seconds is required for carrying out the operations of SIM card deactivation and reactivation after timing is finished, and only 12S V I power consumption is required to be consumed, so that compared with the case that one application exists in the background of the user equipment 200, 32S V I power consumption is totally saved. It can be understood that, for some background applications with more frequent interactions, the frequency of sending messages by the server may be more frequent, and the communication management method provided by the embodiment of the present application may save more power consumption. It can be understood that, when the user equipment 200 has a plurality of background applications, more power consumption can be saved by using the communication management method provided in the embodiment of the present application, so as to reduce the power consumption of the user equipment 200.

Please refer to fig. 5, which is a sub-flowchart of step S300 in fig. 4. As shown in fig. 5, the method for determining the type of the trigger event includes:

s310: whether it is a closed data switch.

It is understood that if the type of the triggering event is that the ue 200 turns off the data switch, step S410 is performed, that is, the first Backoff (Backoff) timing duration is set.

If the type of the trigger event is not the off data switch, step S320 is executed to continuously determine the type of the trigger event.

It is to be understood that the trigger event off data switch detection may be applicable to the user equipment 200 in fig. 2 and the user equipment 201 in fig. 3.

S320: whether it is a switch to Wi-Fi.

It is understood that if the type of the trigger event is switching to Wi-Fi, step S420 is executed, i.e. the second back-off timing duration is set.

If the type of the trigger event is not to switch to Wi-Fi, step S330 is executed, i.e., the type of the trigger event is continuously determined.

It is to be understood that the switching of the trigger event to Wi-Fi detection may be applicable to the user equipment 200 in fig. 2 and the user equipment 201 in fig. 3.

S330: whether it is a switch master card.

It is understood that if the type of the trigger event is to switch the master card, step S430 is performed, that is, the third back-off timing duration is set.

If the type of the trigger event is not the switch master card, step S340 is executed.

It is to be understood that the trigger event switch master card detection may be applied to the user equipment 200 in fig. 2 and the user equipment 201 in fig. 3.

S340: whether it is a smart dual card to switch to a secondary card.

It is understood that if the type of the triggering event is the smart dual card switching to the secondary card, step S440 is executed to set the fourth back-off timing duration.

If the type of the trigger event is not the smart dual card switching to the secondary card, step S350 is executed.

It is to be understood that the triggering event smart dual card switch to secondary card detection may be applicable to the user equipment 201 in fig. 3.

S350: whether it is a smart dual card to switch to the master card.

It is understood that if the type of the trigger event is the smart dual card switching to the master card, step S450 is executed to set the fifth back-off timing duration.

If the type of the trigger event is not the smart dual card switching to the master card, step S800 is executed to end the determination process.

It is understood that the triggering event smart dual card switch to master card detection may be applicable to the user equipment 201 in fig. 3.

It is understood that after the backoff timing duration setting is completed, step S500 is performed, that is, the internet PDN deactivation operation is completed.

It is understood that, referring to fig. 4 again, in step S200, the SIM card registers the IMS PDN connection after activating the PDN default bearer. Therefore, if there is no IMS PDN connection currently, it may be considered that the SIM card has no unbroken PDN connection, and the SIM card corresponding to the first cellular mobile communication network is not woken up by the packet.

It is understood that the user equipment 200 sends an attach request and establishes an IMS bearer when accessing the core network 300. Therefore, if the ue 200 supports VoLTE, two PDN connections are established after accessing the core network 300. One is an Internet (Internet) PDN connection, which has a qci (qos Class identifier) of usually 9 for sending and receiving data packets. The other is an IMS PDN connection, where the QCI of the IMS PDN connection is usually 5 to transmit IMS signaling (e.g. control plane signaling for voice call), and when a voice call is performed, a dedicated PDN connection with QCI of 1 is re-established to implement voice packet transmission.

In the embodiment of the application, the detection efficiency of the communication management method can be improved and invalid operation can be reduced by detecting the IMS PDN connection.

The communication management method provided by the application can determine whether PDN connection deactivation operation needs to be executed by detecting whether IMS PDN connection exists. And if the IMS PDN connection exists, the deactivation operation is required to be executed, and if the IMS PDN connection does not exist, the deactivation operation is not required to be executed. The networking situation of the user equipment 200 can be confirmed by detecting the IMS PDN connection, avoiding sending a connection detach request to a PDN connection that has failed.
