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 embodiment of the application provides a network switching method, a network switching device, a storage medium and a terminal. The network switching device may be integrated in a network device, and the network device may be a server or a terminal.
For example, as shown in fig. 1, the network switching device is integrated in the first terminal. The first terminal detects a call request with a second terminal; firstly, determining whether a cell where a first network connected currently is located supports a call service; if not, searching the candidate network which can be connected currently and supports the conversation service, and obtaining a candidate network set, and then; selecting a second network from the candidate network set, wherein the network type of the second network is different from that of the first network; then, switching the first network into a second network, and responding to the call request through the second network to achieve the purpose of establishing communication connection with the second terminal; then, extracting a signal identification mark from the network information of the first network, and identifying the position of the first network signal source through the signal identification mark; finally, when the disconnection of the communication connection is detected, the second network is switched to the first network based on the position of the source of the first network signal.
The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
In this embodiment, a description will be given from the perspective of a network switching device, where the network switching device may be specifically integrated in a network device, and the network device may be a server or a terminal; the terminal can comprise a smart phone, a tablet computer and other devices.
Referring to fig. 2, fig. 2 is a first flowchart illustrating a network handover method according to an embodiment of the present disclosure. The method comprises the following specific processes:
In some embodiments, the detected call request between the first terminal and the second terminal may be a call request sent by the first terminal to the second terminal, that is, the first terminal makes a call; or the call request sent by the second terminal to the first terminal, which is received by the first terminal, may be received by the first terminal, that is, the first terminal answers the call.
When the first terminal selects not to answer, the first terminal will not switch the network and is still in the state of connecting the first network; when the first terminal sends a call request to the second terminal, the second terminal can also choose to answer or not answer, and similarly, when the second terminal chooses not to answer, the first terminal cannot switch the network.
In some embodiments, the step "determining whether the cell in which the currently connected first network is located supports the call service" when the first terminal establishes the communication connection with the second terminal may include the following procedures:
acquiring network information of the first network; extracting a call indication identifier from the network information, wherein the call indication identifier indicates whether the first network supports a call service; and judging whether the first network supports the call service according to the call indication identifier.
The network information of the first network may include frequency band information, frequency point information, identification information of a cell where the first network is located, identification information of a first network base station, and the like, and the information at least includes a call indication identifier that may be used to indicate whether the network supports a call service.
In some embodiments, two situations may occur in determining whether the cell in which the first network is located supports the call service.
If the cell in which the first network is located supports the call service, when the first terminal detects a call request with the second terminal, the first network only needs to respond to the call request, so that the communication connection with the second terminal is completed.
If the cell in which the first network is located does not support the call service, a connectable candidate network set needs to be searched near the current location of the first terminal, and a network with a type different from that of the first network is selected from the connectable candidate network set, that is, the selected network mainly aims to support the call service, so that the communication connection with the second terminal is completed.
The screened network can be a 1G, 2G, 3G or 4G network communication system. The 1G network communication system belongs to an analog cellular network, and the first generation mobile communication technology uses multiple cellular base stations, allowing users to move freely during a call and seamlessly transmit the call between adjacent base stations; the 2G network communication system belongs to a digital network, the second generation mobile communication technology uses digital transmission to replace simulation, the efficiency of searching the network by the telephone is improved, the distance between base stations is shortened due to the massive establishment of the base stations, the coverage area required to be born by a single base station is reduced, and the higher-quality signal coverage is provided; the 3G network communication system belongs to high-speed IP data network, the third generation mobile communication technology is characterized in that packet switching is used to replace circuit switching in data transmission, the circuit switching enables data transmission such as voice and the like between mobile phones, the packet switching converts the voice and the like into digital format, and data packet transmission including voice, video and other multimedia contents is carried out through the Internet; the 4G network communication system belongs to an all-IP data network, and all Voice calls in the fourth generation mobile communication technology are converted into VoIP (Voice over Internet Protocol) through digital conversion, so that calls in the 4G network can depend on a wired or wireless network without necessarily requiring mobile signal coverage.
And 103, selecting a second network from the candidate network set.
In some embodiments, the manner of selecting a network from the set of networks supporting the call service to perform communication connection with the second terminal may be: determining a signal strength of each candidate network in the set of candidate networks; ranking the each candidate network based on the signal strength.
The stronger the signal strength in the candidate network becomes a priority option for network switching, and when the candidate network in the front row is unable to connect, the candidate network in the front row is selected according to the priority from strong to weak in signal strength, so as to select the optimal second network supporting the call service to complete the call request with the second terminal.
In some embodiments, the manner of selecting a network from the network set supporting the call service to perform communication connection with the second terminal may also be: determining a network type for each candidate network in the set of candidate networks; acquiring a call network connection priority corresponding to the network type; and ranking each candidate network according to the connection priority of the call network.
The network type of the candidate network is determined to divide the call quality of each candidate network into priority, the candidate network with the optimal call quality can be a priority selection item for network switching, and a user can select the candidate networks in sequence according to the priority of the call quality so as to select the optimal second network supporting the call.
And step 104, switching the first network to the second network, and responding to the call request through the second network to establish communication connection with the second terminal.
In some embodiments, the first network is switched to the second network, so that the network supporting the call service can be selected to complete the communication connection with the second terminal.
For example, in the initial stage of deployment of a 5G network communication system, many operators cannot provide a call service to a terminal on the 5G network, and therefore when the terminal needs to perform a call service, the 5G network needs to be switched to another network supporting the call service to meet the call requirement. Here, taking the case that the 5G network falls back to the 4G network, the mode generally adopted is EPS (evolved packet system) Fallback. The work flow is that the first terminal connects to a 5G network cell, that is, a NG-RAN (Radio Access network of 5G), wherein the NG-RAN may include a gNB (node providing a user with NR (new Radio over the air) user plane and control plane protocol terminals and is connected to a 5GC via an NG interface), a NG-eNB (node providing a user with E-UTRA (Evolved-UMTS Terrestrial Radio Access) user plane and control plane protocol terminals and is connected to a 5GC via an NG interface), a 5GC (5G core network) and an NG interface (interface between Radio Access network and 5G core network), and so on. The core network finds that the 5G network cell does not support the call service, so a 4G network cell is searched near the 5G network cell, and the 4G network cell can provide the call service to the terminal based on VOLTE (Voice over Long-Term Evolution Voice bearer), and establishes a communication connection in the 4G network cell, and in the process of switching the 5G network to the 4G network, the core network needs to initiate a call request again in the 4G network cell again to complete the communication connection with the second terminal.
The VOLTE technology is a high-speed wireless communication standard for mobile phones and data terminals. Based on an IMS (IP multimedia subsystem) network, it uses configuration files tailored to a Control plane and a Media plane on LTE (Long-Term Evolution), which enables voice services to be transmitted as data streams in an LTE data bearer network without maintaining and relying on a conventional circuit-switched voice network. The VOLTE technology has the advantages of shorter user turn-on latency and higher quality, more natural voice-video call effect.
In some embodiments, the case that the first terminal has two SIM cards may specifically be:
the first terminal may include a first SIM card and a second SIM card, the first SIM card is connected with the first network, the second SIM card is connected with a third network, wherein the network types of the first network and the third network are different, and the first terminal currently establishes a communication connection with the second terminal through the first SIM card, including;
when the cell where the first network is located does not support the call service, judging whether the cell where the third network is located supports the call service; if so, switching the first network to the third network, and responding to the call request through the third network to establish communication connection with the second terminal; if not, searching the candidate network which can be connected currently to obtain a candidate network set, wherein the network type of the candidate network is different from that of the first network.
In some embodiments, if the cell in which the first network connected to the first SIM card is located supports a call service, when the first terminal detects a call request with the second terminal, the first terminal only needs to respond to the call request through the first network to complete a communication connection with the second terminal without performing a network switching operation.
And 105, switching the second network to the first network when the communication connection is detected to be disconnected.
In some embodiments, before switching the second network to the first network, the method may further include: recording network messages of the first network; extracting a signal identification from the network information, wherein the signal identification is used for identifying the position of a signal source of the first network;
the switching the second network to the first network may include: identifying the signal source position of the first network according to the signal identification mark; switching the second network to the first network based on the signal source location.
In some embodiments, after the first terminal completes the communication request with the second terminal, it needs to locate a source location of the first network to which the first terminal is connected before establishing the communication connection, and search for the first network based on the source location, so as to implement the handover from the second network to the first network.
The network information of the first network may include frequency band information, frequency point information, identification information of a cell where the first network is located, identification information of a first network base station, and the like, and the information at least includes a signal identification identifier that can be used for identifying a first terminal signal source.
The network switching method provided by the embodiment comprises the following steps: firstly, a call request with a second terminal is detected, and a cell where a connected first network is located does not support a call service is judged, so that a current connectable candidate network is searched again to obtain a candidate network set, wherein the network type of the candidate network supports the call service, a second network is selected from the candidate network set, then the first network is switched to the second network, the call request is responded through the second network to establish communication connection with the second terminal, then the position of a signal source of the first network is recorded, and when the disconnection of the communication connection is detected, the second network is switched to the first network. The embodiment aims at searching other networks supporting the communication service from the vicinity of the currently connected 5G network position to realize communication connection because the 5G network does not have the communication function when a user performs communication connection because the services supported by different types of networks are different; when the communication connection is disconnected, the network is switched to the 5G network connected before the communication connection, so that the normal use of the terminal function is ensured, the effectiveness and the use efficiency of the network connected with the terminal are improved, and the communication quality of the terminal is improved.
The method described in the previous embodiment is further detailed by way of example.
The embodiment will be described from the perspective of a network switching device, which is specifically integrated in a smart phone, wherein a first terminal is a mobile phone a, and a second terminal is a mobile phone B. Referring to fig. 3, a network handover method may specifically include the following steps:
In some embodiments, the detected call request between the mobile phone a and the mobile phone B may be a call request sent from the mobile phone a to the mobile phone B, that is, the mobile phone a makes a call; or the call request sent from the mobile phone B to the mobile phone a, which is received by the mobile phone a, may be received, that is, the mobile phone a answers the call.
When the mobile phone A selects to answer or not answer the call request sent by the mobile phone B, the mobile phone A does not switch the network and is still in a state of connecting with the first network; when the mobile phone a sends a call request to the mobile phone B, the mobile phone B can also choose to answer or not answer, and similarly, when the mobile phone B chooses not to answer, the mobile phone a does not switch the network.
In some embodiments, when the mobile phone a establishes the communication connection with the mobile phone B, the determining whether the cell in which the currently connected first network is located supports the call service may include: acquiring network information of a first network; extracting a call indication identifier from the network information, wherein the call indication identifier indicates whether the first network supports a call service; and judging whether the first network supports the call service according to the call indication identifier.
The network information of the first network may include frequency band information, frequency point information, identification information of a cell where the first network is located, identification information of a first network base station, and the like, and the information at least includes a call indication identifier that may be used to indicate whether the network supports a call service.
If the cell in which the first network is located supports the call service, when the mobile phone a detects the call request with the mobile phone B, the mobile phone a only needs to respond to the call request through the first network, thereby completing the communication connection with the mobile phone B.
And step 204, searching the candidate networks which can be connected currently to obtain a candidate network set, wherein the network type of the candidate network is different from that of the first network.
If the cell in which the first network is located does not support the call service, a connectable candidate network set needs to be searched near the current location of the mobile phone a, and a network with a type different from that of the first network is selected from the connectable candidate network set, that is, the selected network mainly aims to support the call service, so as to complete the communication connection with the mobile phone B.
In some embodiments, the manner of selecting a network from the network set supporting the call service to perform communication connection with the mobile phone B is described as follows:
the first method comprises the following steps: determining a signal strength of each candidate network in the set of candidate networks; ranking the each candidate network based on the signal strength.
The stronger the signal strength in the candidate network becomes a priority option for network switching, and when the candidate network in the front row is unable to connect, the candidate network in the front row is selected according to the priority from strong to weak in signal strength, so as to select the optimal second network supporting the call service to complete the call request with the second terminal.
And the second method comprises the following steps: determining a network type for each candidate network in the set of candidate networks; acquiring a call network connection priority corresponding to the network type; and ranking each candidate network according to the connection priority of the call network.
The network type of the candidate network is determined to divide the call quality of each candidate network into priority, the candidate network with the optimal call quality can be a priority selection item for network switching, and a user can select the candidate networks in sequence according to the priority of the call quality so as to select the optimal second network supporting the call.
In some embodiments, the first network is switched to the second network, so that the network supporting the call service can be selected to complete the communication connection with the second terminal.
In some embodiments, the case that the mobile phone a may have two SIM cards may specifically be: the mobile phone A can comprise a first SIM card and a second SIM card, the first SIM card is connected with a first network, the second SIM card is connected with a third network, the network types of the first network and the third network are different, and the mobile phone A establishes communication connection with the mobile phone B through the first SIM card currently, and the communication connection can comprise the first SIM card and the second SIM card;
when the cell where the first network is located does not support the call service, judging whether the cell where the third network is located supports the call service; if so, switching the first network to a third network, and responding to the call request through the third network to establish communication connection with the mobile phone B; if not, searching the candidate network which can be connected currently to obtain a candidate network set, wherein the network type of the candidate network is different from that of the first network.
In some embodiments, if the cell in which the first network connected to the first SIM card is located supports a call service, when the mobile phone a detects a call request with the mobile phone B, the mobile phone a only needs to respond to the call request through the first network without performing a network switching operation, so as to implement a communication connection with the mobile phone B.
In some embodiments, before switching the second network to the first network, the method may further include: recording network messages of the first network; and extracting a signal identification mark from the network information, wherein the signal identification mark is used for identifying the position of the signal source of the first network.
The network information of the first network may include frequency band information, frequency point information, identification information of a cell where the first network is located, identification information of a first network base station, and the like, and the information at least includes a signal identification identifier that can be used for identifying a first terminal signal source.
And step 208, when the communication connection with the mobile phone B is detected to be disconnected, switching the second network to the first network.
In some embodiments, switching the second network to the first network may include: identifying the signal source position of the first network according to the signal identification mark; switching the second network to the first network based on the signal source location.
After the mobile phone a completes the communication request with the mobile phone B, it is required to locate the signal source location of the first network to which the mobile phone a is connected before establishing the communication connection, and search for the first network based on the signal source location, so as to implement the switching from the second network to the first network.
In summary, the 5G network is taken as the first network, and the 4G network is taken as the second network, for example, as follows: firstly, a mobile phone B initiates a call request to a cell in which a 5G network in which the mobile phone A is positioned, and because the 5G network does not support call services, the mobile phone A sends a notification instruction to enable the mobile phone B to be in communication connection with an optimal 4G network nearby, and simultaneously records frequency band, frequency point information and the like of the cell in which the current 5G network is positioned; then the mobile phone B establishes communication connection with the cell where the 4G network is located; after the call is finished, based on the recorded frequency band and frequency point information of the 5G network, the 4G network can automatically initiate registration to the cell where the 5G network is located, so that the mobile phone A is reconnected to the 5G network.
As can be seen from the above, the network switching method provided in this embodiment may search a currently connectable candidate network to obtain a candidate network set on the premise that a cell where the currently connected first network is located does not support a call service when the first terminal detects a call request with the second terminal, then select the second network from the candidate network set, switch the first network to the second network, then respond to the call request through the second network to establish a communication connection with the second terminal, then record a signal source location of the first network, and switch the second network to the first network when detecting that the communication connection is disconnected. The embodiment aims at searching other networks supporting the communication service from the vicinity of the current network position to realize communication connection if the current network does not have the communication function when a user performs communication connection because services supported by different types of networks are different; when the communication connection is disconnected, the network is switched to the network connected before the call connection is carried out, so that the normal use of the terminal function is ensured, the effectiveness and the use efficiency of the network connected with the terminal are improved, and the communication quality of the terminal is improved.
