In the related art, in the process of using the VoWiFi network to make a call by the electronic device, if the electronic device continues to make a call without sound, the VoWiFi network is directly switched to the VoLTE network.

However, since the network quality of a VoWiFi network is generally higher than that of a VoLTE network, not all scenarios with silent talk require switching the VoWiFi network to the VoLTE network (e.g., short network delay of the VoWiFi network).

Therefore, the electronic equipment can be caused to carry out unnecessary network switching, the use power consumption of the electronic equipment is increased, and the conversation efficiency of the electronic equipment is reduced.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The following explains the terms appearing in the present application:

1. VoWiFi network

A VoWiFi network, i.e. Voice over Wi-Fi, is a Voice service based on IP Multimedia Subsystem (IMS). When the user uses the network, the user can carry out voice and video calls in a traditional dialing mode under a Wi-Fi environment.

2. VoLTE network

VoLTE networks, voice over LTE, are IMS-based Voice services. When the user uses the network, the user does not need to start the 2G/3G network, all services (including voice or video call services and internet access services) are borne on the 4G network, and the unification of data transmission and voice call services in the same network can be realized.

3. VoNR network

The VoNR network, i.e. Voice over New Radio, is an IMS-based Voice service. When the user uses the network, the user does not need to start a 2G/3G/4G network, all services (including voice or video call services and internet access services) are borne on the 5G network, and the unification of data transmission and voice call services in the same network can be realized.

4. Session initiation protocol SIP

SIP (Session Initiation Protocol) is a multimedia communication Protocol, and is mainly used for solving signaling control in an IP network, is widely applied to Circuit Switched (CS) and IMS networks, can support and be applied to multimedia services such as voice, video, data, and the like, and can also be applied to feature services such as Presence (Presence), instant Message (Instant Message), and the like.

In the actual communication process, the SIP protocol can be used to establish, modify and terminate multimedia sessions for two or more parties over IP networks. When the IMS communication technology is used between different electronic devices to establish communication connection, the electronic devices send SIP signaling, if the communication connection is normal, the signaling can be sent normally, and the network device feeds back information aiming at the SIP signaling.

5. Internet key exchange protocol IKE

IKE defines a method for identity authentication, negotiating encryption algorithms and generating shared session keys between communicating entities for negotiating and establishing security associations, exchanging keys, between two communicating entities. After the key is exchanged between the two communicating entities, secure communication using Internet Protocol Security (IPSec) may be started.

In the actual communication process, the electronic device periodically sends an IKE network address translation Keep-Alive (NAT Keep Alive) message to the network device at a certain interval, if the data transmission function of the electronic device is normal, the IKE signaling can be sent normally, and after receiving the IKE signaling, the network device feeds back feedback information about the IKE signaling to the electronic device.

6. Hypertext transfer protocol HTTP

HTTP is the most widely used network transport protocol on the internet, and all World Wide Web (WWW) documents must adhere to this protocol. In practical applications, when the electronic device needs to connect to a network and execute a service consuming data traffic (for example, viewing a web page), an HTTP connection request needs to be initiated to the network device, and if the data transmission function of the electronic device is normal, the request signaling can be sent out normally, and the network device will feed back feedback information about the request signaling.

7. Real-time Transport Protocol (RTP)/real-time Transport Control Protocol (RTCP)

In the field of communications, the RTP standard defines two sub-protocols, RTP and RTCP. In the data transmission process, the electronic device usually uses RTP and RTCP together. Among them, RTP is a transport protocol for multimedia data stream on internet, which aims to guarantee synchronization of time information and data transmission when transmitting data. RTCP is responsible for managing the quality of transmission to exchange control information between current application processes. RTCP packets, which contain statistics such as the number of packets sent and the number of packets lost, are transmitted periodically during a session by the electronic device according to RTP.

In an actual communication process, when data needs to be transmitted between electronic devices, RTP/RTCP data from a network device needs to be received, and if a data transmission function of the electronic device is normal, the electronic device may receive the data.

The network connection method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

The network connection method provided by the embodiment of the application can be applied to the call scene of the voice service based on the IMS. When using VoWiFi, the network connection device may be in a Call Active state (Call Active) or a non-Call state (IDLE). After the electronic device and the network device establish IPSec connection through VoWiFi (for example, an access gateway of 4G VoWiFi is ePDG, and an access gateway of 5G VoWiFi is N3 IWF), the electronic device and the network device start a DPD Timer (most operators set the DPD Timer to 2 minutes), respectively, using a Timer, so as to periodically detect a network connection status.

If the network device does not receive the feedback of any data packet in the electronic device within the DPD Timer time, the network device considers that the IPsec connection with the electronic device is interrupted, and at this time, the network device disconnects the IKE connection with the electronic device, the connection between the electronic device and the network device fails, and the electronic device is triggered to switch from the VoWiFi network to the VoLTE network; if the electronic device does not receive the feedback of any data packet in the network device within the DPD Timer time, the electronic device considers that the IPSec connection with the network device is interrupted, and the electronic device generates a DPD Timer timeout error signaling, and then switches the network from the VoWiFi network to the VoLTE network.

As can be seen from the above, when the VoWiFi network cannot transmit data, the electronic device directly performs network switching when the DPD Timer times out, and in the VoWiFi network, the electronic device cannot transmit data for various reasons, such as network delay. Therefore, the DPD Timer timeout does not necessarily indicate that the VoWiFi network cannot transmit data. Generally, the network environment of the VoWiFi network is better than that of the VoLTE network, and unnecessary network handover may be caused because the DPD Timer timeout is not accurate as a criterion for determining the type of the handover network.

In the embodiment of the application, when the electronic device is connected to the VoWiFi network, if the electronic device detects that the backhaul of the VoWiFi network is interrupted, the electronic device initiates a detection command to detect the real data transmission state of the VoWiFi network, and then obtains a detection result. When the electronic equipment confirms that the data transmission state is the interruption state, the VoWiFi network is switched to the VoLTE network. Therefore, the electronic equipment can obtain an accurate detection result by actively initiating the detection command, so that the accuracy and the effectiveness of network switching are enhanced.

The network connection method in the embodiment of the present application is described below with reference to a flow chart of the network connection method shown in fig. 1, where fig. 1 is a flow chart of the network connection method provided in the embodiment of the present application, and the flow chart includes steps 201 and 202:

step 201: the network connection device initiates a detection command to obtain a detection result if detecting that the return trip of the VoWiFi network is interrupted under the condition that the electronic equipment is connected to the VoWiFi network.

In an embodiment of the application, the detection result is used to indicate a data transmission status between the electronic device and the VoWiFi network.

In this embodiment of the present application, the network backhaul interruption refers to: after the electronic device establishes a connection with the network device, the data transmission line from the electronic device to the network device to transmit data is interrupted, and the data transmission line from the network device to the electronic device is interrupted.

It should be noted that, when the network backhaul of the VoWiFi network is interrupted, the network connection between the electronic device and the network device is not interrupted, and only the VoWiFi network cannot be used for data transmission.

In this embodiment of the application, the detection command may be: a command for detecting a connection status between the network connection device and the network device. For example, an Internet Packet explorer command (Ping) in the electronic device may check whether a data transmission channel between the electronic device and the network device is clear.

In this embodiment, the detection result is a detection result generated by the electronic device after the electronic device sends the detection command. For example, after the electronic device sends the Ping command to the network device, the availability of the data transmission channel may be checked and determined, and a detection result about the data transmission status may be generated, so that a network failure may be accurately analyzed and determined.

In an example, after the electronic device initiates a Ping command, the electronic device may transmit a data packet to the network device, and request the network device to transmit a feedback data packet having the same size as the data packet back to the electronic device, and when the electronic device cannot send the data packet or cannot receive the feedback data packet, the electronic device may determine that the data transmission status is an interruption status.

Step 202: if the data transmission state is an interruption state, the network connection device switches the electronic equipment from the VoWiFi network to a target network.

For example, after the electronic device confirms that the data transmission state is the interruption state, the electronic device quickly switches the VoWiFi network to the target network.

In an example, when the electronic device is in a process of using a VoWiFi network to perform a voice call, if the VoWiFi network cannot transmit data, the electronic device may directly switch the VoWiFi network to a target network when it is determined that a data transmission state is interrupted, thereby reducing a situation that no voice occurs during the call, and implementing seamless switching between different networks.

Illustratively, the target network may be a VoLTE network or a VoNR network. That is, in the case that the electronic device supports a 5G network, the network connection device may switch the aforementioned VoWiFi network to a VoNR network; or, in the case that the electronic device supports the LTE network, the network connection device may switch the aforementioned VoWiFi network to the VoLTE network.

Example 1: when the network connection device is connected with the VoWiFi network, when the network connection device cannot transmit data to the network equipment, the electronic equipment is triggered to initiate a Ping command (namely the detection command) to the network equipment, a feedback result (namely the detection result) of the Ping command is obtained, and when the feedback result shows that the data transmission state of the network connection device and the VoWiFi network is an interruption state, the network connection device cuts off the connection with the VoWiFi network and switches to be connected with the VoLTE network.

In the network connection method provided in the embodiment of the application, when the electronic device is connected to the VoWiFi network, if the electronic device detects that the backhaul of the VoWiFi network is interrupted, the electronic device initiates a detection command to detect the data transmission state of the VoWiFi network, and then obtains a detection result, and when the data transmission state is the interrupted state, the electronic device is switched from the VoWiFi network to the target network. Therefore, when the electronic equipment detects that the return trip of the VoWiFi network is interrupted, the electronic equipment initiates a detection command to perform secondary detection, so that the current data transmission state of the VoWiFi network is accurately judged, unnecessary network switching is reduced, and the accuracy and the effectiveness of the network switching are improved.

Optionally, in this embodiment of the present application, before initiating the detection command in step 201, the network connection method provided in this embodiment of the present application further includes step a of:

step A: and if the electronic equipment meets the preset condition, the network connection device determines that the return trip of the VoWiFi network is interrupted.

In an embodiment of the present application, the predetermined condition includes at least one of: the electronic device fails to send the first information to the network device when the electronic device does not receive the feedback information sent by the network device.

In this embodiment of the application, the first information may be signaling transmitted by the electronic device and the network device in a connection process, or may be data information sent by the electronic device to the network device.

In one example, the signaling is: signaling transmitted between the electronic device and the network device in the process of using VoWiFi based on the existing communication protocol; the data information may be: data information transmitted between different electronic devices during a conversation, for example, voice data packets transmitted between electronic devices during voice communication or video data packets transmitted between electronic devices during video communication.

In this embodiment of the application, the feedback information is feedback information sent to the electronic device by the network device after receiving the first information sent by the electronic device.

In this embodiment of the application, when the electronic device meets the predetermined condition, the electronic device may be automatically triggered to actively initiate a detection command, and further confirm a data transmission state between the electronic device and the network device.

Therefore, by setting the predetermined condition, when the electronic equipment does not meet the predetermined condition, the electronic equipment can be automatically triggered to initiate a detection action, so that the detection condition is added to the data transmission state, the detection frequency is increased, and the time consumed for switching the electronic equipment from the VoWiFi network to the target network when the data transmission is interrupted is further reduced, so that the IMS conversation technology of the electronic equipment can be continuously used, and the efficiency of using the IMS conversation technology by a user is finally improved.

Optionally, in this embodiment of the present application, before initiating the detection command in step a, the network connection method provided in this embodiment of the present application further includes step B:

and B, step B: and the electronic equipment sends second information to the network equipment.

For example, the receiving, by the electronic device, the feedback information sent by the network device includes: and feedback information sent by the network equipment in response to the second information is not received within the preset time.

Optionally, the second information may refer to the description of the first information, and is not described herein again.

For example, the predetermined time period may be set in advance by the electronic device according to a system-set feedback time of the second information. It is understood that, if the second information is information (for example, SIP signaling or RTP/RTCP data) transmitted between the electronic device and the network device, according to a communication protocol followed by the information, after the electronic device sends the information to the network device, the network device needs to send feedback information to the electronic device within a predetermined time.

For example, the predetermined time periods corresponding to different second information may be different. It can be understood that different second information corresponds to different communication protocols, and in different communication protocols, feedback times of predetermined network devices after receiving the second information are different, and thus predetermined time lengths corresponding to different second information may be different.

Therefore, after the electronic device sends the second information, the data transmission state can be confirmed according to the feedback information of the network device to the second information, and the currently connected network type is switched. Since the second information for confirming the data transmission state is information transmitted based on the existing protocol, compared with the related art, the electronic device does not need to increase power consumption, that is, the electronic device can monitor the data transmission state in time without increasing dedicated information for confirming the data transmission state.

Optionally, in this embodiment, the electronic device may send, to the network device, second information that is not identical according to different current use states.

For example, in a case that the electronic device is in a call state, the second information includes at least one of: SIP signaling, IKE signaling, HTTP protocol connection signaling, RTP/RTCP data.

In one example, after the electronic device enters a call state, the electronic device may send voice data or video data of the call to one or more other electronic devices. The voice data or the video data are RTP/RTCP data, the RTP/RTCP data are encapsulated in a data packet, the data packet is transmitted between different electronic devices through a network device, and the electronic devices transmit or receive the RTP/RTCP data at periodic intervals.

Therefore, when the electronic equipment cannot send out the RTP/RTCP data or does not receive the RTP/RTCP data within the preset time, the electronic equipment can be triggered to initiate a detection command to detect the current data transmission state.

In one example, when a session is established, terminated, or modified between an electronic device and another electronic device (e.g., a media parameter between electronic devices changes), the electronic device sends SIP signaling to the network device, and if a data transmission state is normal, the network device feeds back feedback information of the SIP signaling to the electronic device.

Therefore, when the electronic equipment cannot send out the SIP signaling or does not receive the feedback information of the SIP signaling within the preset time, the electronic equipment can be triggered to initiate a detection command to detect the current data transmission state.

In one example, after the electronic device establishes a connection with the network device, IKE signaling is periodically sent to the network device to confirm that the information transmission is secure in the current network connection state.

Therefore, when the electronic equipment cannot send out the IKE signaling or does not receive the feedback information of the IKE signaling within a preset time, the electronic equipment can be triggered to initiate a detection command to detect the current data transmission state.

In one example, when the electronic device needs to initiate a web service through a network device (e.g., view a web page), the electronic device needs to initiate HTTP connection signaling to initiate the web service through the network device.

Therefore, when the electronic equipment cannot initiate the HTTP connection signaling to the network equipment or does not receive the feedback information of the HTTP connection signaling within the preset time, the electronic equipment can be triggered to initiate the detection command to detect the current data transmission state.

For example, in the case that the electronic device is in a non-call state, the second information includes at least one of: the IKE message, and the HTTP protocol connection message.

For example, the IKE signaling and the HTTP protocol connection signaling may refer to the above description, and are not described herein again.

Therefore, after the electronic equipment is connected with the network equipment, when the electronic equipment transmits the second information with the network equipment, the data transmission state between the electronic equipment and the network equipment can be detected in time by detecting the feedback state of the second information, and then the network is switched in time when the data transmission state is interrupted. And, the electronic device can confirm the current data transmission state by using more second information than the non-call state in the call state. Therefore, when the electronic device uses the VoWiFi network to carry out real-time call, if the data transmission state is interrupted, the switching between the VoWiFi network and the target network can be completed in a very short time, the continuity of receiving voice or video images in the call state is maintained, and the seamless switching between different networks is achieved.

Optionally, in this embodiment of the present application, when the second information includes the target data packet, before initiating the detection command in step B, the network connection method provided in this embodiment of the present application further includes step C:

and C: when the electronic device receives a first target data packet, the network connection device starts a timer, and restarts the timer when a next target data packet of the first target data packet is received and the timer is not overtime.

Illustratively, the destination packet may be a packet containing RTP/RTCP data.

For example, the timer may be a time period used in the electronic device to calculate an interval between the electronic device receiving different data packets. It will be appreciated that when the electronic device receives a packet, the time counted before the timer is cleared, and is counted again from 0.

Illustratively, when the first target packet is the electronic device starts a timer, the timer starts to count time from 0 and then receives the first packet.

For example, the timer does not time out, and the target duration of the timer does not exceed the target predetermined duration. The target duration refers to a duration actually calculated by a timer, and the target preset duration may be preset by the electronic device according to a communication protocol.

Example 2: assume that the speed at which the electronic device receives the data packets is 1/second and the target duration set by the timer is 3 seconds. When the electronic equipment receives an RTP/RTCP data packet containing voice data in a call state, the electronic equipment starts a timer when receiving a data packet 1, and starts the timer again when receiving a data packet 2 after 1 second, clears 1 second accumulated and calculated by the previous timer, and counts by 0 again. When the electronic equipment does not receive the data packet 3 within 3 seconds after receiving the data packet 2, a Ping command is initiated, the data transmission state between the network connection device and the network equipment under the VoWiFi network is detected, and when the data transmission state is interrupted, the network connection device switches the currently connected VoWiFi network to the VoLTE network.

Therefore, the electronic equipment sets the target preset time length by setting the timer, and confirms that the subsequent data packet of the target data packet is not received in the target preset time length, so that the data transmission function of the VoWiFi network is determined to be invalid and the VoWiFi network is switched to the target network. Therefore, the trueness and the accuracy of the data transmission state confirmation of the network connection device can be improved.
