Fig. 1 schematically shows a system architecture diagram for implementing the network handover method, and as shown in fig. 1, the system architecture 100 may include a first end 101, a base station 102, a network 103, and a second end 104. The first end 101 may include, among other things, various handheld devices (cell phones) with communication capabilities, vehicle mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and so forth. The base station 102 refers to a radio transceiver station for information transfer with a mobile phone terminal through a mobile communication switching center in a radio coverage area. The base station 102 may be an LTE (Long Term Evolution) base station, a 5G (5th-Generation, fifth Generation mobile communication technology) base station, and so on. An application server may be a server accessed by a client through an application program for returning data to the client in response to a user request. The network 103 may be an operator core transport network, and specifically includes a network corresponding to 3G (3rd-Generation, third Generation mobile communication technology), 4G (the4th Generation mobile communication, fourth Generation mobile communication technology), 5G, and so on. The network 103 is used to provide a medium for communication link between the first end 101 and the second end 104, the network 103 may include various connection types, such as a wired communication link, a wireless communication link, and the like, and in the embodiment of the present disclosure, the network 103 between the first end 101 and the second end 104 may be a wired communication link, such as a communication link provided by a serial connection line, or a wireless communication link, and the communication link is provided by a wireless network.

On this basis, in the embodiment of the present disclosure, the first end 101 is connected to the network 103 through the base station 102 so as to access the application server 104, thereby establishing a communication connection between the client and the application server. Whether the network 103 connected with the client is abnormal or not can be determined according to the round-trip delay of the client for sending the data packet to the application server and receiving the data packet, so that the network can be switched according to the duration of the abnormal state and various switching modes.
It should be understood that the number of first ends, networks and second ends in fig. 1 is merely illustrative. There may be any number of first ends, networks, and second ends, as desired for the implementation.
Based on the system architecture, the embodiment of the present disclosure provides a network switching method, as shown in fig. 2, which can be applied in any application scenario where a terminal device connects to a network, and the network switching method in the embodiment of the present disclosure can be executed by the network itself.
Next, a network handover method in the embodiment of the present disclosure is described in detail with reference to fig. 2 to 4.
In step S210, if it is determined that the connection state of the network of the terminal device is an abnormal state according to the round trip delay of the data packet, the duration of the abnormal state is determined.
In the embodiment of the present disclosure, the data packet refers to a TCP packet in a TCP/IP (Transmission Control Protocol/Internet Protocol ) Protocol. The TCP transmission protocol is a reliable end-to-end protocol, and each TCP packet needs to receive an ACK (acknowledgement character) from the opposite end before transmission is successful. The TCP connection process is implemented based on three-way handshake, and specifically includes: if the server B communicates with the client A, when the client A communicates with the server B, the client firstly sends a data packet marked by SYN (synchronization sequence numbers) to the server, and tells the server to request to establish connection; then, after receiving the acknowledgement packet (SYN/ACK) sent by the server, the server indicates the acknowledgement of the first SYN packet and continues the handshake operation; after the client receives the SYN/ACK packet, the client sends an acknowledgement packet ACK to inform the server that the connection is established. At this point, three handshakes are completed and one TCP connection is completed.
Two important fields are contained in a data packet, namely a TCP packet: SEQ and ACK, where SEQ indicates the size of a data packet that has been transmitted in the current direction, and ACK indicates the size of an opposite-end data packet that has been successfully received by the terminal device. When the terminal device has a data packet to send to the opposite end after the three-way handshake is completed, the SEQ number of the terminal is the starting position of the data to be sent currently, and is, for example, 3; the packet size transmitted is then 1400bytes, assuming that the packet is P0, at which time the terminal device records the time of transmission T0. When the peer end receives successfully, a data packet is replied, wherein ACK is the SEQ number sent by the terminal device plus the size of the sent data packet, that is, 1403, the data packet is assumed to be P1. The time from the terminal sending P0 to the terminal receiving the opposite data packet P1 is the round trip delay of the terminal sending the data packet P0. For this reason, the round trip delay refers to the time interval between the time when the terminal device transmits the data packet and the time when the acknowledgement data packet transmitted by the opposite end (e.g., the server) is received. And, the round trip delay here refers to a time interval in a unit time.
The network of the terminal device refers to a network to which the terminal device is currently connected, for example, a 4G network provided by a first operator or a 5G network provided by a second operator, and so on. The connection state is used to describe the connection quality of the network, and the connection state may include a normal state and an abnormal state, where the normal state refers to a case where the network connection is stable and no delay or interruption occurs. The abnormal state refers to a case where the network connection is not smooth and unstable (i.e., a stuck state), and the abnormal state may also be a case where the network is disconnected. The abnormal state may cause that data cannot reach the terminal device in real time, resulting in a situation of a large data transmission delay. Determining the connection state of the network of the terminal device according to the round trip delay of the data packet includes: if the round-trip delay of the data packet in unit time is larger than a round-trip threshold value, determining that the connection state of the terminal equipment is an abnormal state; and if the round-trip delay of the data packet in unit time is not greater than the round-trip threshold, determining that the connection state of the terminal equipment is a normal state. The round trip threshold may be set to a large value, for example 1 minute. That is, the time when the terminal device sends the data packet 1 is determined, the time when the terminal device receives the acknowledgement data packet for the data packet 1 sent by the opposite terminal (server) is obtained, and the round-trip delay in the unit time is further determined according to the time interval between the sending time and the receiving time. Still further, a comparison result between the round trip delay and the round trip threshold may be determined, and the connection state of the network of the terminal device may be determined according to the comparison result. For example, if the round trip delay is 10 seconds, the connection status may be considered as a normal status; if the round trip delay is 80 seconds, the connection state can be considered as an abnormal state. The connection state of the network can be accurately identified through the round-trip delay of the data packet, and then the network is processed in time.
In the embodiment of the present disclosure, the duration of the abnormal state refers to the length of time that the abnormal state occurring this time lasts, and may be, for example, 1 minute or 5 minutes, or the like. Specifically, the duration of the abnormal state may be determined according to the duration of the data transmission is not smooth, and the data transmission is not smooth and may be represented as: the operation interface (such as a page or a display) maintains a fixed state and is always in a network connection state. Based on the method, the duration of the abnormal state of the network can be accurately determined, so that the network can be switched in time according to the duration.
In step S220, if the duration of the abnormal state satisfies the network handover condition, the network of the terminal device is actively triggered to be handed over by combining multiple handover modes.
In the embodiment of the present disclosure, the network handover condition is used to indicate a limitation condition of the handover network to evaluate the duration, and may specifically be represented by a duration threshold, for example, 5 minutes or 10 minutes, and so on. Based on this, it can be determined whether the duration satisfies the set network switching condition to obtain the determination result. The judgment result can be two conditions that the duration time meets the network switching condition or the duration time does not meet the network switching condition, and the judgment results are different, and the processing processes of the network are also different. When the network switching condition is met, switching the network; and when the network switching condition is not met, the network is not switched. On the basis of step S210, a specific determination process of whether to switch the network may be as shown in fig. 3, with reference to fig. 3, and mainly includes the following steps: in step S310, determining whether the round-trip delay of the transmission of the data packet per unit time exceeds a round-trip threshold; if yes, go to step S320; if not, step S310 is executed again. In step S320, it is determined whether the duration of the transmission round trip delay exceeding the round trip threshold is greater than a preset duration threshold. If yes, go to step S330; if not, go to step S310. In step S330, it is determined that the data transmission is not smooth and a network handover condition is satisfied.
In the technical scheme in fig. 3, whether the network is in an abnormal state can be determined through the round trip delay of the data packet, and then whether the network is switched is determined according to whether the abnormal duration is greater than the persistence threshold.
When the duration meets the network switching condition and the network of the terminal equipment is switched, the network of the terminal equipment can be switched by combining various switching modes. The switching mode may specifically include any one of cell switching, access point name switching, and data card switching, and a priority order, i.e., a sequence order, exists among the multiple switching modes. The sequence is a cell switching mode, an access point name switching mode and a data card switching mode. Of course, other switching sequences are possible.
First, a cell switching method will be described. The cell switching mode refers to that the terminal equipment is registered in a certain cell to obtain network service, and when the terminal equipment processes a connection state, the network issues a switching instruction through measurement reporting, so that the terminal equipment is switched to another service cell from a current service cell. The switching the network of the terminal device comprises: and when the duration of the abnormal state meets the network switching condition, adjusting the signal receiving quality values of the current serving cell and the adjacent serving cell, and triggering the network to switch when the adjusted signal receiving quality values of the current serving cell and the adjacent serving cell meet the cell switching condition. The current serving cell refers to a cell in which the terminal device currently resides, that is, a communication cell currently performing signaling and data transmission with the terminal device. It may be detected whether a neighboring serving cell (neighboring cell) is configured for a current serving cell in which the terminal device is located. If the neighboring cell configured for the serving cell is detected, the neighboring cell identifier configured for the serving cell can be fed back to the terminal, so that a guarantee is provided for the terminal to execute network switching, and the network of the terminal device can smoothly execute the network switching step. That is, cell handover is premised on the current serving cell being configured with a neighboring serving cell. A neighbor cell refers to two cells covered with an overlap and provided with a handover relationship, and one serving cell may have a plurality of neighbor cells. The function of the neighboring cell is to enable the terminal device to perform smooth alternation of services among a plurality of service cells defining the neighboring cell relationship in a mobile state without interruption. Only if the neighbouring cell is added, the terminal device can switch between different networks, such as GSM, UMTS.
The specific step of adjusting the signal reception quality values of the current serving cell and the neighboring serving cells may include: and reducing the signal reception quality value of the current serving cell and increasing the signal reception quality value of the adjacent serving cell with the maximum signal strength. The signal reception quality value may specifically be expressed in terms of signal strength. The adjustment amplitude for the current serving cell may be a first amplitude and the adjustment amplitude for the neighboring serving cell may be a second amplitude. The first amplitude and the second amplitude may be equal or different, and are not limited herein. Specifically, if the signal reception quality value of the current serving cell does not satisfy the cell switching condition, it may be reduced until the signal reception quality value satisfies the cell switching condition; if the signal reception quality value of the current serving cell already satisfies the cell switching condition, it may be continued to be decreased on the basis until stopping when the network of the current serving cell is poor as indicated by a very small signal reception quality value (for example, a limit threshold may be set, and the limit threshold is much smaller than the preset threshold). At the same time, the signal reception quality value of the neighbouring serving cell can be increased to induce the network to switch automatically by the adjustment operations acting on the terminal equipment. Where the cell handover conditions are provided by the network and the handover network is a decision of the network itself. It should be noted that there are multiple neighboring serving cells configured for the current serving cell, and in order to ensure the fluency after network handover, one of the neighboring serving cells with the highest signal strength may be used as the neighboring serving cell to be handed over.
Further, if the adjusted signal reception quality value of the network of the terminal device meets the cell switching condition, the network of the terminal device is switched from the current serving cell to the adjacent serving cell. The cell handover condition is used to trigger and guide the network to handover to another serving cell, and specifically to determine whether to execute a cell handover method. In the embodiment of the present disclosure, the cell switching condition may be at least one of the following: the signal receiving quality value of the current serving cell is smaller than a preset threshold, the signal receiving quality value of the adjacent serving cell is larger than that of the current serving cell, the signal receiving quality value of the adjacent serving cell is larger than the preset threshold, the signal receiving quality value of the current serving cell is smaller than the preset threshold, and the signal receiving quality value of the adjacent serving cell is larger than the preset threshold. The preset threshold is used for judging whether the signal receiving quality value meets the cell switching condition, and the preset threshold can be a larger value. Cell handover conditions may also be triggered by handover events.
When the terminal equipment is surfing the internet, the terminal equipment is in a connected state. When the terminal equipment is in a connected state, the signal receiving quality values of the current service cell and the adjacent cell are adjusted and reported to the network, and the network is triggered and guided to be switched to the adjacent cell. The specific operation is to reduce the signal reception quality value of the current serving cell, increase the signal reception quality value of the neighboring cell with the best signal, if the signal reception quality value of the network exceeds the preset threshold of a plurality of switching events A2/A3/A4/A5 set by the current serving cell, the network triggers cell switching, and at the moment, the terminal device is switched to the neighboring cell, so as to achieve the purpose of leaving the current serving cell with unsmooth data transmission. The current serving cell and the neighboring serving cell may be in the same system with the same network type or in different systems with different network types, and are not limited herein. For example, if the current serving cell is 4G and if the TCP delay is particularly large, the TCP delay is still poor after attempting to handover to the 4G neighbor cell, it may be considered to handover to a neighbor serving cell of a different type from the current serving cell. When determining the neighbor serving cells of the different systems, the determination may be performed according to a priority order, where the priority of the 5G neighbor is greater than the priority of the 3G neighbor. Therefore, the specific process of determining the neighboring serving cell includes: and determining the adjacent service cell with the strongest signal in the same system, and if the data transmission is still not smooth after the switching, determining the adjacent service cell to be switched from the different system according to the priority order, thereby realizing the accurate and effective switching of the network.
The switching event specifically includes: a handover event a2, where the current serving cell is worse than a preset threshold; this event may be used to turn on measurements between certain cells, since a handover or the like may occur after this event has occurred. Handover event a3, neighbor serving cell better than current serving cell; this event occurrence can be used to decide whether the terminal device is handed over to a neighbouring serving cell. Handover event a4, the neighbor serving cell is better than the preset threshold. Handover event a5, the current serving cell is worse than a preset threshold and the neighboring serving cell is better than an absolute threshold; this event may also be used to support handover.
Then, after the cell switching mode, the connection state of the network of the terminal device can be continuously determined according to the round trip delay of the data packet, and whether the network after the cell switching mode triggers a network switching condition is further judged based on the connection state. If the duration of the abnormal state meets the network switching condition, the network switching can be continuously performed through the access point name switching mode after the cell switching mode. If the duration of the abnormal state does not meet the network switching condition, the network switching is not required to be carried out through the access point name switching mode after the cell switching mode. Specifically, switching the network of the terminal device in the access point name switching manner includes: if the data card used by the terminal equipment has a plurality of access point name configurations, switching the access point name from the current access point name to another access point name; establishing a network connection based on the other access point name. The data card refers to a SIM (Subscriber Identity Module) card currently used for connecting a network in the terminal device. The access point name device configuration refers to apn (access point name), which is a parameter that a user must configure when accessing the internet through the terminal device, and determines which access method the terminal device accesses the mobile network through. The APN setting may include: CMWAP (access to WAP services via GPRS), CMNET (services other than WAP currently use CMNET, such as internet connectivity, etc.). And the name of the APN setting for each service provider (operator) may be different but the function is the same.
When the duration of the abnormal state is determined to meet the network switching condition again according to the round-trip delay after the cell switching mode, the terminal equipment can automatically detect whether a plurality of APN configurations exist in the currently used data card. If there are multiple APN configurations, the access point name is changed from the current access point name to another access point name. Further, the network connection is established on the basis of the name of the other access point. A Network connection here refers to a PDN (Packet Data Network) connection for the purpose of leaving the currently poorly transported PDN Data Network. For example, the name of the current access point is CMWAP, if a network handover condition is detected to be triggered again, the name of the access point is switched to CMNET, and PDN connection is established on the basis of CMNET. Among them, PDN connection refers to an all-IP LTE system, and accessing a packet data network is an important means for data transmission. The PDN connection procedure is an important procedure for the LTE communication system to access the packet data network, and aims to establish a default bearer between the UE and the packet data network. The unique identification information of each PDN connection includes an access point name APN and a PDN address used by each PDN connection, or includes a PDN type, an APN and a PDN address used, and so on for each PDN connection.
Further, after the access point name switching mode is performed, the connection state of the network of the terminal device can be determined continuously according to the round-trip delay of the data packet, and whether the network switching condition is met or not is further judged. If the duration of the abnormal state meets the network switching condition, the network switching can be continuously carried out in a data card switching mode. If the duration of the abnormal state after the access point name switching mode does not meet the network switching condition, the network switching does not need to be carried out continuously in a data card switching mode. It should be noted that the data card switching method is applicable to dual-card or multi-card terminal devices. Specifically, switching the network of the terminal device in a data card switching manner includes: and if the terminal equipment comprises a plurality of data cards, switching the current data card to another data card, and establishing network connection based on the provider network of the other data card.
In the embodiment of the present disclosure, the plurality of data cards refer to SIM cards currently loaded in the terminal device, and the types of the plurality of data cards may be the same or different. The current data card refers to a data card currently used for connecting a network, and may be any one of a plurality of data cards. Another data card refers to a data card other than the currently used data card among the plurality of data cards.
If the access point name is switched, the terminal equipment still detects that the TCP packet round-trip delay reaches the condition of triggering network switching, the terminal equipment automatically detects whether the terminal equipment has a plurality of data cards for registration, and if so, the data is switched to another data card. The network connection can be further established based on the provider network of another data card for the purpose of leaving the terminal device from the carrier network that is not currently streaming data. For example, for a dual-card terminal in which a terminal device supports two or more cards to register in a network at the same time, if the network state when using the data card 1 still satisfies the network switching condition, the data card 1 is switched to the data card 2, so as to perform network connection through the data card 2. It should be added that switching the data card network may also include switching to a wireless hotspot network, for example, to a wifi hotspot network. After the switching, whether the abnormal state meets the network switching condition is still determined through the round trip delay of the data packet, so that the switching operation of the network is automatically triggered and executed according to the steps.
Fig. 4 schematically shows a flow chart of network handover, and referring to the flow chart shown in fig. 4, the method mainly includes the following steps:
in step S410, it is determined that data transmission is not smooth, and the smooth time exceeds a predetermined persistence threshold. That is, the duration of the abnormal state of the network meets the network switching condition.
In step S420, the signal reception quality values of the current serving cell and the neighboring serving cells reported by the measurement are adjusted to guide the network to switch the serving cells.
In step S430, it is determined whether the data transmission is not smooth (i.e., whether the network handover condition is satisfied). If yes, go to step S440. If not, go to step S410.
In step S440, the other access point name, i.e. the packet data network connection of the network, is switched to guide the network handover.
In step S450, it is determined whether the data transmission is not smooth (i.e., whether the network handover condition is satisfied). If yes, go to step S460. If not, go to step S410.
In step S460, another data card is switched to guide network switching, and the process goes to step S410 to continue detecting.
Through the technical scheme in fig. 4, the network is guided to be switched by using various switching modes with different dimensions according to the sequence between the switching modes by combining different switching modes. Because a certain sequence exists among different switching modes, the switching modes can be selected according to the sequence, and the process of guiding the network to actively switch is realized through the most appropriate switching mode. The problem that other devices need to wait for passively switching the network in the related technology is solved, and the initiative is improved.
In the embodiment of the disclosure, since the round trip delay of the data packet is determined as a basis for determining whether the network is abnormal, whether the connection state of the network is abnormal can be accurately determined. When the duration of the abnormal state meets the network switching condition, the network switching of the terminal equipment can be automatically triggered, the problem that the terminal equipment can only wait and passively switch the network in the related technology is avoided, the waiting time is reduced, the network switching efficiency and timeliness are improved, and the network switching reliability is also improved. Whether the network switching condition is met or not can be determined according to the round-trip delay of the data packet, the network can be rapidly switched by combining multiple switching modes according to the priority sequence, the condition for judging the network switching is simplified, the switching delay is reduced, the problem of network blockage can be solved more simply, conveniently and timely, the network stability is improved, the problem of transmission interruption caused by network interruption is reduced, and the data transmission performance and the data transmission real-time performance are improved.
