图1是本申请一实施例提供的用户设备通信场景的示意图。FIG. 1 is a schematic diagram of a user equipment communication scenario provided by an embodiment of the present application.

请参阅图1，用户设备200通过第一蜂窝网络接入点301连接至第一应用服务器301，并通过第二网络接入点302连接至第二应用服务器402。Referring to FIG. 1 , theuser equipment 200 is connected to thefirst application server 301 through the first cellularnetwork access point 301 , and is connected to thesecond application server 402 through the secondnetwork access point 302 .

可以理解的是，用户设备200包括，但不限于，便携式或移动设备、手机、平板电脑、电视、个人数字助理、膝上型设备、台式机、手持PC、服务器、网络设备、图形设备、视频游戏设备、机顶盒、蜂窝电话、便携式媒体播放器、手持设备、可穿戴设备(例如，显示眼镜或护目镜、头戴式显示器、手表、头戴设备、臂带、珠宝等)、虚拟现实和/或增强现实设备、物联网设备、工业控制设备、车载信息娱乐设备、流媒体客户端设备、电子书阅读设备、POS机、或者能够进行无线通信和/或有线通信的其他电子设备。It will be appreciated thatuser equipment 200 includes, but is not limited to, portable or mobile devices, cell phones, tablet computers, televisions, personal digital assistants, laptops, desktops, handheld PCs, servers, network devices, graphics devices, video Gaming devices, set-top boxes, cellular phones, portable media players, handheld devices, wearable devices (eg, display glasses or goggles, head-mounted displays, watches, headsets, armbands, jewelry, etc.), virtual reality and/or Or augmented reality devices, IoT devices, industrial control devices, in-vehicle infotainment devices, streaming media client devices, e-book reading devices, POS machines, or other electronic devices capable of wireless and/or wired communication.

可以理解的是，用户设备200可以支持一张或多张用户身份识别模块(SubscriberIdentity Module，SIM)卡。每个蜂窝移动通信网络对应一张SIM卡。为了便于描述，本申请实施例中将SIM卡以及其演进都统称为SIM卡。例如SIM卡可以是全球移动通信系统(GlobalSystem For Mobile Communications，GSM)数字移动电话用户的身份识别卡，用于存储用户的身份识别码和密钥，并支持GSM系统对用户的鉴权。又例如，SIM卡也可以是全球用户识别卡(Universal Subscriber Identity Module，USIM)，也可以称为升级SIM卡。It can be understood that theuser equipment 200 may support one or more subscriber identity module (Subscriber Identity Module, SIM) cards. Each cellular mobile communication network corresponds to a SIM card. For ease of description, the SIM card and its evolution are collectively referred to as a 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, which is used to store the user's identification code and key, and supports the authentication of the user by the GSM system. For another example, the SIM card may also be a universal subscriber identity module (Universal Subscriber Identity Module, USIM), which may also be called an upgraded SIM card.

可以理解的是，当用户设备200可以支持多张SIM卡时，主SIM卡可以为长期演进(Long Term Evolution，LTE)制式或5G非独立网组(Non-Standalone，NSA)制式。副SIM卡可以为支持全球移动通信系统(Global System For Mobi1eCommunication，GSM)制式、通用移动通信系统(Universal Mobi1 eTelecommunications System，UMTS)制式、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)制式、长期演进(Long Term Evolution，LTE)制式、码分多址(Code Division Multiple Access，CDMA)制式、新系统(New System，NS)制式、5G非独立网组(Non-Standalone，NSA)制式、5G独立网组(Standalone，SA)制式等。It can be understood that when theuser equipment 200 can support multiple SIM cards, the primary SIM card can be a Long Term Evolution (Long Term Evolution, LTE) standard or a 5G Non-Standalone (Non-Standalone, NSA) standard. The secondary SIM card may support Global System For Mobi1eCommunication (GSM) standard, Universal Mobile Telecommunications System (UMTS) standard, Time Division-Synchronous Code Division Multiple Access (Time Division-Synchronous Code Division Multiple Access) TD-SCDMA), Long Term Evolution (LTE), Code Division Multiple Access (CDMA), New System (NS), 5G Non-Standalone (Non-Standalone) , NSA) standard, 5G independent network group (Standalone, SA) standard, etc.

可以理解的是，当用户设备200可以支持多张SIM卡时，则用户设备200可以支持双卡数据并发功能或非双卡数据并发功能。It can be understood that, when theuser equipment 200 can support multiple SIM cards, theuser equipment 200 can support a dual-SIM data concurrent function or a non-dual-SIM data concurrent function.

可以理解的是，用户设备200可以通过第一蜂窝网络接入点2301接入蜂窝移动通信网络与其他设备进行通信。用户设备200还可以通过第二网络接入点302接入蜂窝移动通信网络或通过无线通信技术(Wi-Fi)与其他设备进行通信。It can be understood that theuser equipment 200 can access the cellular mobile communication network through the first cellular network access point 2301 to communicate with other devices. Theuser equipment 200 can also access a cellular mobile communication network through the secondnetwork access point 302 or communicate with other devices through a wireless communication technology (Wi-Fi).

可以理解的是，服务器在与用户设备200内的应用建立连接之后，可能会向应用发送轮询、长连接及推送消息。示例性的，长连接包括用户数据报协议(User DatagramProtocol，UDP)连接及传输控制协议(Transmission Control Protocol，TCP)连接等。It can be understood that, after establishing the connection with the application in theuser equipment 200, the server may send polling, long connection and push messages to the application. Exemplarily, the persistent connection includes a User Datagram Protocol (User Datagram Protocol, UDP) connection and a Transmission Control Protocol (Transmission Control Protocol, TCP) connection, and the like.

可以理解的是，当用户设备200内的应用与服务器建立基于UDP的连接之后，由于UDP不会提供用户设备的在线状态，因此服务器端与用户设备200通常会使用周期性报文来确定用户设备200是否在线。It can be understood that after the application in theuser equipment 200 establishes a UDP-based connection with the server, since UDP does not provide the online status of the user equipment, the server and theuser equipment 200 usually use periodic packets to determine the user equipment. 200 is online.

可以理解的是，当用户设备200内的应用与服务器通过三次握手建立TCP连接之后，只要该连接未被关闭连接(Finish，FIN)或重置连接(Reset，RST)，则用户设备200和服务器端可以认定对端均在线。然而，在实际应用中，用户设备200和服务器端均会发送心跳包来检测对端的连接状态，以及时发现对端是否在线。It can be understood that after the application in theuser equipment 200 establishes a TCP connection with the server through the three-way handshake, as long as the connection is not closed (Finish, FIN) or reset (Reset, RST), theuser equipment 200 and the server The peers can determine that the peers are all online. However, in practical applications, both theuser equipment 200 and the server will send a heartbeat packet to detect the connection status of the peer, and find out in time whether the peer is online.

示例性的，如图1所示，用户设备200包括第一应用(Application，APP)210和第二应用220。当用户设备200内的第一应用210通过第一蜂窝网络接入点301与第一应用服务器401建立UDP或TCP连接之后，用户设备200从第一蜂窝移动通信网络切换至其他网络。此时，用户设备200与第一蜂窝移动通信网络建立连接之后会至少保留一个公用数据网(PublicData Network，PDN)连接，在切换至其他网络之后不会主动切断PDN连接。尽管在用户设备200端与第一蜂窝移动通信网络之间的连接在接入网侧已经断开，但是由于用户设备200与第一蜂窝移动通信网络之间仍保留有至少一条PDN连接，即，用户设备200的第一蜂窝移动通信网络在核心网处于挂起状态而非切断状态。因此，对于核心网来说，用户设备200依然是在线。在一些场景下，如果用户设备从第一蜂窝移动通信网络切换到其他网络，例如Wifi网络或者第二蜂窝移动网络，此时第一蜂窝网络的核心网还认为用户设备200在线。此时应用服务器可能认为用户设备还通过第一蜂窝网络连接，依然会通过第一蜂窝网络给用户设备发送数据报文。这些报文会唤醒第一蜂窝移动通信网络对应的主卡，影响其他卡，例如副卡的上网性能。具体地，若用户设备200支持双卡数据并发功能，由于双卡数据并发功能常通过时分多路复用(Time Division Multiplexing，TDM)功能实现，则重新唤醒第一蜂窝移动通信网络对应的主卡会影响其他蜂窝移动网络的带宽并增加用户设备200的功耗。具体地，若用户设备200不支持双卡数据并发功能，则重新唤醒第一蜂窝移动通信网络对应的主卡会占用用户设备200的射频(Radio Frequency，RF)资源，影响其他蜂窝移动网络的带宽等性能。Exemplarily, as shown in FIG. 1 , theuser equipment 200 includes a first application (Application, APP) 210 and asecond application 220 . After thefirst application 210 in theuser equipment 200 establishes a UDP or TCP connection with thefirst application server 401 through the first cellularnetwork access point 301, theuser equipment 200 switches from the first cellular mobile communication network to another network. At this time, after theuser equipment 200 establishes a connection with the first cellular mobile communication network, at least one public data network (Public Data Network, PDN) connection will remain, and will not actively cut off the PDN connection after switching to another network. Although the connection between theuser equipment 200 and the first cellular mobile communication network has been disconnected on the access network side, at least one PDN connection still remains between theuser equipment 200 and the first cellular mobile communication network, that is, The first cellular mobile communication network of theuser equipment 200 is in a suspended state rather than a disconnected state in the core network. Therefore, for the core network, theuser equipment 200 is still online. In some scenarios, if the user equipment is switched from the first cellular mobile communication network to another network, such as a Wifi network or the second cellular mobile network, the core network of the first cellular network also considers theuser equipment 200 to be online at this time. At this time, the application server may consider that the user equipment is still connected through the first cellular network, and will still send data packets to the user equipment through the first cellular network. These messages will wake up the main card corresponding to the first cellular mobile communication network, and affect the Internet access performance of other cards, such as the auxiliary card. Specifically, if theuser equipment 200 supports the dual-card data concurrency function, since the dual-card data concurrency function is often implemented by a time division multiplexing (Time Division Multiplexing, TDM) function, the main card corresponding to the first cellular mobile communication network is re-awakened It will affect the bandwidth of other cellular mobile networks and increase the power consumption of theuser equipment 200 . Specifically, if theuser equipment 200 does not support the dual-card data concurrency function, reawakening the main card corresponding to the first cellular mobile communication network will occupy the radio frequency (Radio Frequency, RF) resources of theuser equipment 200 and affect the bandwidth of other cellular mobile networks. and other performance.

再例如，若用户设备200已经从第一蜂窝移动通信网络切换至Wi-Fi网络，由于第一蜂窝移动通信网络的互联网PDN连接并未断开，因此在第一应用210通过Wi-Fi网络向第一应用服务器401发送数据包之前，第一应用服务器301无法知晓用户设备200已经从第一蜂窝移动通信网络切换至Wi-Fi网络。因此，第一应用服务器401在向用户设备200中的第一应用210发送数据包时，仍会使用第一蜂窝移动通信网络进行数据包发送。而每次唤醒第一蜂窝移动通信网络对应的主卡会建立无线资源控制层(Radio Resource Control，RRC)连接，提升了用户设备200的功率消耗及流量消耗。For another example, if theuser equipment 200 has been 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 has not been disconnected, thefirst application 210 sends data to the Wi-Fi network through the Wi-Fi network. Before thefirst application server 401 sends the data packet, thefirst application server 301 cannot know that theuser equipment 200 has been switched from the first cellular mobile communication network to the Wi-Fi network. Therefore, when thefirst application server 401 sends a data packet to thefirst application 210 in theuser equipment 200, it still uses the first cellular mobile communication network to send the data packet. Each time the main card corresponding to the first cellular mobile communication network is woken up, a radio resource control layer (Radio Resource Control, RRC) connection will be established, which increases the power consumption and traffic consumption of theuser equipment 200 .

可以理解的是，用户设备200内的第二应用220在通过第二网络接入点302与第二应用服务器402建立连接时，第二应用服务器402接收到的连接信息是来自第二网络接入点302，因此，第二应用服务器402在下发报文时不会唤醒第一蜂窝移动通信网络对应的主卡。It can be understood that, when thesecond application 220 in theuser equipment 200 establishes a connection with thesecond application server 402 through the secondnetwork access point 302, the connection information received by thesecond application server 402 is from the second network access point. Atpoint 302, therefore, thesecond application server 402 will not wake up the main card corresponding to the first cellular mobile communication network when delivering the message.

可以理解的是，用户设备200内的应用的运行状态可以分为前台应用、后台应用及常驻应用等。可以理解的是，由于前台应用与服务器的交互较为频繁，在交互的过程中应用与服务器进行数据收发时，会附上最新的网络互连协议(Internet Protocol，IP)等最新参数，因此不容易出现唤醒第一蜂窝移动通信网络对应的主卡的情况。而由于后台应用及常驻应用等应用与服务器的交互频率较低，因此，在服务器侧未获取后台应用及常驻应用未更新的IP等参数时，会将报文下发至第一蜂窝移动通信网络，进而导致第一蜂窝移动通信网络对应的主卡被唤醒。It can be understood that the running states of the applications in theuser equipment 200 can be divided into foreground applications, background applications, resident applications, and the like. It is understandable that since the interaction between the foreground application and the server is relatively frequent, when the application and the server send and receive data, the latest parameters such as the latest Internet Protocol (IP) will be attached, so it is not easy. A situation of waking up the main card corresponding to the first cellular mobile communication network occurs. However, due to the low frequency of interaction between applications such as background applications and resident applications and the server, when the server side does not obtain parameters such as the IP of the background application and the resident application that have not been updated, the packet will be sent to the first cellular mobile phone. communication network, thereby causing the main card corresponding to the first cellular mobile communication network to wake up.

图2是用户设备200的模块示意图。FIG. 2 is a block diagram of theuser equipment 200 .

请参阅图2，用户设备200还包括应用处理器(Application Processor，AP)230、基带(Modem)处理器240、主SIM卡250及Wi-Fi模组260。Referring to FIG. 2 , theuser equipment 200 further includes an application processor (Application Processor, AP) 230 , a baseband (Modem)processor 240 , amain SIM card 250 and a Wi-Fi module 260 .

可以理解的是，应用处理器230的全称为多媒体应用处理器(multimediaapplication processor，MAP)，指在低功耗中央处理器CPU的基础上拓展了音视频功能和专用接口的超大规模集成电路。应用处理器230能够运行复杂的类似Linux内核(Andriod内核)、鸿蒙内核(Harmony内核)、Windows内核等操作系统，多媒体型处理器指处理媒介超过两种的处理器，例如图像、声音、视频以及3D图形等媒介。单一多媒体型处理器是指处理一种媒介的处理器，通常仅用于处理图像或声音。It can be understood that the full name of theapplication processor 230 is a multimedia application processor (MAP), which refers to an ultra-large-scale integrated circuit that expands audio and video functions and dedicated interfaces on the basis of a low-power central processing unit CPU. Theapplication processor 230 can run complex operating systems such as the Linux kernel (Andriod kernel), the Harmony kernel (Harmony kernel), the Windows kernel, etc. The multimedia processor refers to a processor that processes more than two kinds of media, such as image, sound, video and 3D graphics and other media. A single multimedia processor refers to a processor that handles one medium, usually only for image or sound.

可以理解的是，基带处理器240是系统芯片中的一个重要部件，相当于一个协议处理器，负责数据的处理和存储，主要由数字信号处理器(Digital Signal Processor，DSP)、微控制器(Micro Controller Unit，MCU)和内存(如flash、闪存)等单元组成，其对应主要功能为负责基带编码或译码、声音编码和语音编码等。目前，基带处理器240不仅支持多种通信标准，还提供多媒体功能以及提供用于多媒体显示器、图像传感器和音频设备相关的通信接口。It can be understood that thebaseband processor 240 is an important component in the system chip, equivalent to a protocol processor, responsible for data processing and storage, mainly composed of a digital signal processor (Digital Signal Processor, DSP), a microcontroller ( Micro Controller Unit, MCU) and memory (such as flash, flash memory) and other units, and its corresponding main functions are responsible for baseband coding or decoding, voice coding and speech coding. Currently, thebaseband processor 240 not only supports a variety of communication standards, but also provides multimedia functions and provides related communication interfaces for multimedia displays, image sensors, and audio devices.

At this time, if thefirst application server 401 sends the data packet to thefirst application 210, it will still be sent to the first cellular mobile communication network. After detecting that the trigger event is switching from the first cellular mobile communication network to the Wi-Fi network, theuser equipment 200 sets the duration of the back-off timer as the second back-off timing duration according to the type of the trigger event. Theuser 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 theuser equipment 200 to the first cellular mobile communication network.

可以理解的是，由于用户设备200在断开与第一蜂窝移动通信网络的连接之后，仍会保留互联网PDN，因此在核心网300侧显示用户设备200仍然在线，可能导致第一应用服务器401下发数据报文时会拉起第一蜂窝移动通信网络，影响用户设备200的数据收发及功耗。使用本申请实施例提供的通信方法可以去激活PDN连接，避免第一蜂窝移动通信网络对应的SIM卡被频繁唤醒。同时，为了提高用户设备200重新连接回第一蜂窝移动通信网络后的连接速度，本申请实施例提供的通信方法还提供了退避定时器，以根据不同的触发事件类型设置不同的退避定时时长。在退避定时器超时后，使用户设备200重新连接回第一蜂窝移动通信网络，使用户设备200可以快速的启用第一蜂窝移动通信网络。It can be understood that since theuser equipment 200 will still retain the Internet PDN after disconnecting from the first cellular mobile communication network, it is displayed on thecore network 300 side that theuser equipment 200 is still online, which may cause thefirst application server 401 to download the Internet PDN. When a data packet is sent, the first cellular mobile communication network will be pulled up, which affects the data transmission and reception and power consumption of theuser equipment 200 . By using the communication method provided by the embodiment of the present application, the PDN connection can be deactivated, so as to prevent the SIM card corresponding to the first cellular mobile communication network from being frequently woken up. Meanwhile, in order to improve the connection speed after theuser equipment 200 is reconnected to the first cellular mobile communication network, the communication method provided by the embodiment of the present application further provides a backoff timer to set different backoff timer durations according to different trigger event types. After the back-off timer expires, theuser equipment 200 is reconnected to the first cellular mobile communication network, so that theuser equipment 200 can quickly enable the first cellular mobile communication network.

可以理解的是，退避定时时长还可以根据用户的使用习惯及其他芯片的数据进行调整。It can be understood that the backoff timing duration can also be adjusted according to the user's usage habits and data of other chips.

示例性的，若用户设备200检测到触发事件从第一蜂窝移动通信网络切换至Wi-Fi网络，而当前Wi-Fi网络的存储标签为公司或家庭，则可以认为用户设备200在较长的时间内不会切换回第一蜂窝移动通信网络，因此可以将第一退避定时器的时长设置为一个较长的时间，例如30分钟或者更长的时间，以降低通信管理方法的触发频率，从而降低用户设备200的功耗。Exemplarily, if theuser equipment 200 detects a trigger event to switch from the first cellular mobile communication network to the Wi-Fi network, and the storage tag of the current Wi-Fi network is a company or a home, it can be considered that theuser equipment 200 is in a long period of time. It will not switch back to the first cellular mobile communication network within a certain time, so the duration of the first backoff timer can be set to a longer time, such as 30 minutes or longer, to reduce the trigger frequency of the communication management method, thereby The power consumption of theuser equipment 200 is reduced.

示例性的，若用户设备200检测到触发事件从第一蜂窝移动通信网络切换至Wi-Fi网络，而GPS或北斗定位芯片检测到用户设备200处于移动状态(即用户设备200未关闭Wi-Fi开关，且在移动的过程中接入了曾接入过的Wi-Fi网络)，则可以认定为用户设备200可能会短时间内切换回第一蜂窝移动网络，则此时可以将第二退避定时时长设置为一个较短的时间，或者不执行去激活互联网PDN操作，以提高用户重新连接回第一蜂窝移动通信网络的速度，提高用户体验。Exemplarily, if theuser equipment 200 detects a trigger event to switch from the first cellular mobile communication network to the Wi-Fi network, and the GPS or Beidou positioning chip detects that theuser equipment 200 is in a mobile state (that is, theuser equipment 200 does not turn off Wi-Fi) switch, and access the previously accessed Wi-Fi network during the movement), it can be determined that theuser equipment 200 may switch back to the first cellular mobile network in a short time, and at this time, the second backoff can be The timing duration is set to a short time, or the operation of deactivating the Internet PDN is not performed, so as to improve the speed of the user reconnecting back to the first cellular mobile communication network and improve the user experience.

示例性的，若用户设备200检测到触发事件关闭数据开关，则可以进一步检测当前的信号强度、当前SIM卡套餐内剩余的数据流量及飞行模式是否开启等信息。例如，当检测到用户设备200当前的信号强度较差，且飞行模式在开启后迅速关闭，则可以认为用户设备200是在重启网络，用户设备200将在去连接第一蜂窝移动通信网络之后重新建立连接，因此无需设置退避定时时长。Exemplarily, if theuser equipment 200 detects a trigger event to turn off the data switch, it can further detect information such as the current signal strength, the remaining data traffic in the current SIM card package, and whether the airplane mode is enabled. For example, when it is detected that the current signal strength of theuser equipment 200 is poor, and the airplane mode is quickly turned off after being turned on, it can be considered that theuser equipment 200 is restarting the network, and theuser equipment 200 will restart after disconnecting from the first cellular mobile communication network. The connection is established, so there is no need to set the backoff timing.
