Referring to fig. 1, fig. 1 schematically shows a flowchart of a network handover method according to an embodiment of the present disclosure, which may include the following steps:
step S110, detecting the data packet transmission condition between the terminal device and the communication opposite terminal, and determining whether the network quality of the terminal device meets the communication requirement according to the data packet transmission condition.
Step S120, when the network quality of the terminal device does not meet the communication requirement, the signal quality values of the current serving cell and the adjacent cell of the terminal device are adjusted according to the signal quality threshold value obtained from the network side, and the adjusted signal quality value is obtained.
Step S130, sending the adjusted signal quality value to the network side, so that the network side determines whether to switch the serving cell according to the adjusted signal quality value and the signal quality threshold.
Step S140, after receiving the cell switching command issued by the network side, switching from the current serving cell to the neighboring cell.
According to the network switching method, the terminal equipment can determine the network quality according to the data packet transmission condition, and compared with the method for determining the network quality through parameters such as signal strength, the network quality can be more accurately reflected by the data packet transmission condition, so that the accuracy of determining the network quality can be improved. Therefore, when the network quality does not meet the communication requirement, the network side switches the serving cell by adjusting the signal quality values of the current serving cell and the adjacent cell. In the embodiment of the disclosure, when the current network quality is poor, the terminal device can be actively switched to the neighboring cell with good network quality, so that normal communication can be quickly recovered, and better internet experience can be obtained.
The execution subject of the embodiment of the present disclosure may be a terminal device, for example, a smart phone, a tablet computer, or the like. Embodiments of the disclosure are described in more detail below:
in step S110, a data packet transmission condition between the terminal device and the correspondent node is detected, and whether the network quality of the terminal device meets the communication requirement is determined according to the data packet transmission condition.
In the disclosed embodiment, the data packet may be a TCP packet, which is a connection-oriented, reliable, byte-stream-based transport-layer communication protocol that is specifically designed to provide a reliable end-to-end byte stream over an unreliable internet network. The communication peer is a peer that communicates with the terminal device, and may be another terminal device, a server, or the like. For example, when the terminal device communicates with the server, the server may be referred to as a correspondent node of the terminal device.
Wherein, the transmission process of the TCP data packet in the TCP/IP protocol comprises the following steps: three-way handshake, data transfer and four-way hand waving. The terminal equipment can carry out three times of communication before transmitting data with the opposite communication terminal, namely three times of handshaking, and when the data transmission is disconnected, four times of communication is carried out, namely four times of waving hands. The TCP transmission protocol is an end-to-end reliable protocol, each TCP data packet needs to receive an Ack from the opposite communication end to calculate the successful transmission, and the TCP data packet that fails in transmission needs to be retransmitted. When the terminal device has a data packet to transmit to the correspondent node after the completion of the three waving operations, if the data packet transmitted by the terminal device is P0, the terminal device records the transmission time T0. When the correspondent node receives successfully, it can reply to the packet P1. The time from the terminal device sending P0 to the time when the terminal device receives the correspondent node data packet P1 is the round trip delay of the terminal sending data packet P0. If the terminal sends three TCP data packets of P0, P1 and P2, and the opposite communication terminal only receives P1, the P0 and P2 lose packets; and the correspondent node only receives P2, which indicates that P0 and P1 lose packets. At this point, the terminal may retransmit the lost packet as specified by the TCP protocol.
Under normal conditions, when the network condition is poor, the probability of packet loss is high, correspondingly, the probability of data packet retransmission is also high, and the transmission delay is long; when the network condition is better, the probability of packet loss is lower, the probability of data packet retransmission is also lower, and the transmission delay is shorter. That is, the packet loss rate, retransmission rate, or transmission delay, etc. may reflect the network condition. Therefore, the data packet transmission condition may be a packet loss rate, a retransmission rate, or a transmission delay of the data packet, and the communication requirement may be that the packet loss rate and the retransmission rate are low, or the transmission delay is short when the terminal device transmits the data packet. The packet loss rate is taken as an example for explanation, and the retransmission rate and the transmission delay are not listed here.
In an exemplary embodiment of the present disclosure, a method for determining whether the network quality of the terminal device satisfies the communication requirement may be seen in fig. 2, and may include the following steps:
step S210, detecting a packet loss rate of a data packet transmitted between the terminal device and the correspondent node in unit time, and determining whether the packet loss rate is greater than a probability threshold.
In the embodiment of the present disclosure, the packet loss rate is a packet loss rate in a certain time period, the time period may be taken as a unit time, and the unit time may be set according to an actual application scenario, for example, may be 1s, 2s, and the like. The terminal device can count the total number of the data packets transmitted between the terminal device and the communication opposite terminal and the total number of the lost data packets in unit time, and the total number of the lost data packets is divided by the total number of the transmitted data packets, so that the packet loss rate can be obtained. When the packet loss rate is greater than the probability threshold, executing step S220; if the packet loss rate is not greater than the probability threshold, go to step S240.
Step S220, determine whether the duration of the packet loss rate greater than the probability threshold is greater than the duration threshold.
As described above, the higher the packet loss rate, the worse the network quality, so that when the packet loss rate is greater than the probability threshold, the network quality can be determined to be worse. Because the network can be recovered to be normal after the network quality is poor for a short time under the condition that the network is unstable, in order to avoid mistaking the condition that the network quality does not meet the communication requirement, the packet loss rate can be continuously monitored, and whether the duration that the packet loss rate is greater than the probability threshold is greater than the duration threshold is judged. That is, it is determined whether the duration time with poor network quality is longer, and if the duration time is longer than the duration threshold, step S230 is executed; otherwise, step S240 is performed. The probability threshold and the duration threshold may be empirically set values, for example, the probability threshold may be 10%, 20%, and the like, and the duration threshold may be 5s, 8s, and the like.
Step S230, determining that the network quality of the terminal device does not meet the communication requirement.
Step S240, determining that the network quality of the terminal device meets the communication requirement.
In the embodiment of the present disclosure, when the network quality of the terminal device does not meet the communication requirement, that is, the network quality of the terminal device meets the condition of triggering network handover, step S120 may be executed; when the network quality of the terminal device meets the communication requirement, the process may return to step S110, that is, the network quality of the terminal device may be re-detected.
In step S120, the signal quality values of the current serving cell and the neighboring cell of the terminal device are adjusted according to the signal quality threshold obtained from the network side, so as to obtain an adjusted signal quality value.
The process of cell switching comprises the following steps: the terminal equipment can obtain network service by registering a certain service cell, and the network side issues a switching instruction by measuring and reporting so that the terminal equipment is switched to another service cell from the current service cell. The signal quality threshold is a value set by the network side to trigger cell switching, and comprises the following steps: a first threshold value and a second threshold value, the first threshold value being less than the second threshold value. The conditions for triggering cell handover may be: the signal quality value of the current serving cell is less than a first threshold, the signal quality value of another serving cell to be handed off is higher than a second threshold, the signal quality value may be a received signal strength, etc.
In the related art, the terminal device may directly report the measured signal quality values of the current serving cell and the neighboring cell to the network side, and the network side determines whether to switch the serving cell according to the signal quality values of the current serving cell and the neighboring cell and the signal quality threshold. In the embodiment of the disclosure, the network quality is determined according to the data packet transmission condition, and the data packet transmission condition can reflect the network quality more accurately compared with the signal quality value of the current serving cell. Therefore, when the network quality of the terminal device does not meet the communication requirement, in order to switch the serving cell at the network side, the signal quality values of the current serving cell and the neighboring cell of the terminal device can be adjusted according to the signal quality threshold to obtain the adjusted signal quality value, so that the adjusted signal quality value meets the condition of triggering cell switching. The terminal device may obtain the signal quality threshold from a system message sent from the network side.
In the process of determining whether to trigger cell handover, since the flows corresponding to different network modes are different, an LTE (Long Term Evolution) network is taken as an example for description herein.
The terminal equipment measures the current service cell to obtain the signal quality of the current service cell. Because operations such as cell switching and the like may occur after the event that the signal quality value of the current serving cell is smaller than the first threshold occurs, if the signal quality value of the current serving cell is larger than the first threshold, the signal quality value of the current serving cell can be reduced, so that the signal quality value of the current serving cell is smaller than the first threshold, and the measurement of the neighbor cell is started through the event. Of course, if the signal quality value of the current serving cell is not greater than the first threshold, the measurement of the neighbor cell may be directly started.
After the terminal device obtains the signal quality value of the neighboring cell through measurement, if the signal quality value of the neighboring cell is greater than the signal quality value of the current serving cell, the event can be used to determine whether the terminal device is switched to the neighboring cell. Since the signal quality value of the neighboring cell is greater than the second threshold in the condition for triggering cell handover, if the signal quality value of the neighboring cell is less than the second threshold, the signal quality value of the neighboring cell may be increased to make the signal quality value of the neighboring cell greater than the second threshold. Thus, the signal quality value of the current serving cell is smaller than the first threshold, and the signal quality value of the neighboring cell is larger than the second threshold, so that the handover condition can be satisfied.
It should be noted that the neighboring cell may be any neighboring cell having a signal quality value greater than that of the current serving cell, and optionally, may be the neighboring cell having the largest signal quality value, that is, the optimal neighboring cell.
In step S130, the adjusted signal quality value is sent to the network side, so that the network side determines whether to switch the serving cell according to the adjusted signal quality value and the signal quality threshold.
In step S120, the terminal device adjusts the signal quality values of the current serving cell and the neighboring cell so that the adjusted signal quality values satisfy the handover condition. Then, after the terminal device sends the adjusted signal quality value to the network side, the network side may determine to switch the serving cell when the adjusted signal quality value of the current serving cell is smaller than the first threshold and the adjusted signal quality value of the neighboring cell is larger than the second threshold. At this time, the network side may issue a cell switching instruction to the terminal device.
In step S140, after receiving a cell switching instruction issued by the network side, the current serving cell is switched to the neighboring cell.
It should be noted that the cell handover may be an intra-system handover, for example, a handover from a current serving cell of the 4G network to a neighboring cell of the 4G network may be performed. The cell handover may be an inter-system handover, for example, a handover from a current serving cell of a 4G network to a neighboring cell of a 3G network. Of course, if a 5G network is already deployed, a handover to a neighbor cell of the 5G network may be prioritized.
Referring to fig. 3, fig. 3 schematically shows another flowchart of a network handover method according to an embodiment of the present disclosure, and after step S140 in the embodiment of fig. 1, the method may further include the following steps:
step S310, whether the network quality of the terminal equipment meets the communication requirement is detected.
In the embodiment of the present disclosure, the processing procedure in this step may be the same as the processing procedure in step S110, and is not described herein again. Step S320 is executed when the network quality of the terminal device does not meet the communication requirement, and step S110 may be returned to when the network quality of the terminal device meets the communication requirement.
Step S320, detecting whether the current data card in the terminal device is configured with a plurality of access point names.
It should be noted that the name of the access network is a parameter configured when the user accesses the internet through the terminal device, and it determines which access method the terminal device accesses the mobile network through. That is, the access point name is an identification of the packet data network, and different access point names correspond to different packet data networks.
The data card can be a user identity identification card, and one data card in the terminal equipment can be configured with a plurality of access point names, so that whether the terminal equipment can be switched to a packet data network corresponding to other access point names can be judged by detecting whether the current data card in the terminal equipment is configured with a plurality of access point names. When the current data card configures a plurality of access point names, step S330 is performed.
And step S330, switching from the packet data network corresponding to the current access point name to the packet data network corresponding to the other access point name.
If the current data card is configured with a plurality of access point names, the terminal equipment can be switched from the current access point name to other access point names, and the packet data network connection is established on the other access point names, so that the purpose of leaving the packet data network with poor network quality is achieved.
Referring to fig. 4, fig. 4 schematically shows another flowchart of a network handover method according to an embodiment of the present disclosure, and after step S330 in the embodiment of fig. 3, the method may further include the following steps:
step S410, detecting whether the network quality of the terminal device meets the communication requirement.
In the embodiment of the present disclosure, the processing procedure in this step may be the same as the processing procedure in step S110, and is not described herein again. Step S420 is executed when the network quality of the terminal device does not meet the communication requirement, and step S110 may be returned when the network quality of the terminal device meets the communication requirement.
Step S420, detecting whether the terminal device includes a plurality of data cards.
Because the terminal device can support a plurality of data cards to register in the network at the same time, after the terminal device is switched to the packet data network corresponding to other access point names, if the network quality still does not meet the communication requirement, whether the terminal device contains a plurality of data cards can be detected, so as to confirm whether the terminal device can access the network corresponding to other data cards. If the terminal device includes a plurality of data cards, step S430 is performed.
And step S430, switching from the network corresponding to the current data card to the network corresponding to the other data card.
It should be noted that the networks corresponding to different data cards may be networks of different operators. The network handover in this step may be a handover between different operator networks. And if the network quality still does not meet the communication requirement after switching to the network corresponding to other data cards, switching to the wireless network.
Therefore, in the network switching method according to the embodiment of the present disclosure, the terminal device detects the packet loss rate or the retransmission rate of the transmitted data packet, and the like, and uses the detected data packet as a basis for determining whether the network quality meets the communication requirement, so that the accuracy of determining the network quality can be improved. The terminal equipment leaves the cell with poor network quality, or leaves the packet data network with poor network quality, or leaves the operator network with poor network quality by actively enabling the network side to switch the service cell, or actively switching the packet data network, or actively switching the data card, so that the purposes of quickly recovering normal communication and optimizing internet experience are achieved.
It should be noted that although the various steps of the methods of the present disclosure are depicted in the drawings in a particular order, this does not require or imply that these steps must be performed in this particular order, or that all of the depicted steps must be performed, to achieve desirable results. Additionally or alternatively, certain steps may be omitted, multiple steps combined into one step execution, and/or one step broken down into multiple step executions, etc.
