Fig. 1 is a flow diagram of a network selection method according to some embodiments of the invention. As shown in fig. 1, the network selection method of this embodiment includes steps S102 to S106.
In step S102, network-connectable information of the current location of the terminal is acquired.
Connectable networks include data communication networks and also voice call networks. The terminal may, for example, search for signals of nearby 2G, 3G, LTE, WiFi, etc. networks. In some embodiments, the network connectable information includes one or more of signal strength, network latency, traffic per unit time, whether a password is required.
In step S104, connection status information of the terminal connected to the correspondent node through the connectable network is acquired.
In addition to knowing the conditions of the network to which the terminal is currently connected, it is also necessary to know the network conditions of the correspondent node. For example, the terminal may send a network diagnosis instruction such as a Ping (Packet Internet Groper) instruction to the correspondent node through the connectable network, so as to obtain connection status information such as network response time; for another example, the terminal may call the opposite terminal to acquire the network condition of the opposite terminal according to whether the call can be connected.
In step S106, a connectable network meeting a preset condition is selected according to the information of the connectable network and the connection status information, so that the terminal performs communication through the selected connectable network.
In making the network selection, the embodiment of the present invention does not refer to only the information of the connectable network, but comprehensively considers the information of the connectable network and the network condition of the opposite terminal. Therefore, it is necessary to select a network in which both the information on the connectable network and the connection status information on the communication counterpart connected via the connectable network satisfy the preset conditions. In some embodiments, a connectable network with a signal strength greater than a preset threshold and a network delay to a correspondent node less than a preset threshold may be selected.
By the method of the embodiment, the information of the connectable network and the network condition of the opposite terminal can be comprehensively considered, and the network meeting the preset condition is selected, so that a stable communication network can be provided for the terminal, and the communication quality and the use experience of the user are improved.
There are some locations where terminals may be frequently present, such as the user's home location, work location, cafes frequently visited by the user, and so on. The embodiment of the invention can also combine the historical habits of the user with the current network condition to select the connected network for the terminal. An embodiment of the network selection method of the present invention is described below with reference to fig. 2.
Fig. 2 is a flow diagram of a network selection method according to further embodiments of the present invention. As shown in fig. 2, the network selection method of this embodiment includes steps S202 to S214.
In step S202, network-connectable information of the current location of the terminal is acquired.
In step S204, connection status information of the terminal connected to the correspondent node through the connectable network is acquired.
In step S206, a historical connection network in which the connection duration of the terminal at the current location is greater than a preset duration is obtained.
Thus, it is possible to know a network in which the terminal has a long stay in the past time. In some embodiments, a history of the terminal in a preset recent period of time may be obtained to obtain a network that the terminal has used recently.
In step S208, a connectable network that meets a preset condition is determined.
In step S210, it is determined whether the connectable networks meeting the preset condition include a historical connected network in which the connection duration of the terminal is greater than the preset duration. If yes, go to step S212; if not, step S214 is performed.
In step S212, a historical connection network having a connection duration longer than a preset duration is selected.
In step S214, an optimal network among the connectable networks that meet the preset condition is selected.
For example, in some embodiments, the score of the connectable network may be a weighted difference between the signal strength of the connectable network and the network delay to the correspondent node, where the predetermined condition is that the score is greater than 100, and the scores of the connectable network A, B, C are 110, 108, and 102, respectively, all of which meet the predetermined condition. If the network B is a network in which the terminal has been in the past for a long time and the networks A and C are not networks in which the terminal has been in the past for a long time, even if the network B is not the network with the highest score, the network B can be selected as the network for the terminal to communicate, so that the terminal can use a common network, and the network stability probability is higher; and if neither network A, B nor C is the network in which the terminal has been staying for a long time in the past, then network a with the highest score may be selected, randomly selected among the three networks, and so on.
By the method of the embodiment, the terminal can select the network which is selected historically as much as possible, so that the communication quality and the user experience can be further improved.
In order to further improve the stability of the network, the network selection may be performed when the information obtained continuously for multiple times all meets the preset condition. An embodiment of the network selection method of the present invention is described below with reference to fig. 3.
Fig. 3 is a flow chart of a network selection method according to further embodiments of the present invention. As shown in fig. 3, the network selection method of this embodiment includes steps S302 to S308.
In step S302, the information of the connectable networks of the current location of the terminal is acquired continuously a preset number of times.
In step S304, the connection status information of the terminal connected to the correspondent node through the connectable network is acquired for a preset number of consecutive times.
In step S304, a connectable network in which the information of the connectable network and the connection status information acquired each time both meet a preset condition is selected.
In step S308, the terminal is instructed to communicate through the selected connectable network.
For example, it may be set that when information acquired three consecutive times satisfies a preset condition, a corresponding connectable network may be selected as a network for terminal communication. Therefore, the stability of the terminal network is further improved.
In the scenario of the calling network application, it is possible to switch to another calling network when the terminal does not successfully call the called terminal through one calling network. An embodiment of the call network selection method of the present invention is described below with reference to fig. 4.
Fig. 4 is a flow chart of a method of call network selection according to some embodiments of the invention. As shown in fig. 4, the network selection method of this embodiment includes steps S402 to S408.
In step S402, the calling terminal initiates a call to the called terminal through the first network.
In step S404, in response to that the terminal unsuccessfully initiates a call to the called terminal through the first calling network, information of the second calling network and connection status information of the calling terminal calling the called terminal through the second calling network are acquired.
In step S406, in response to that the information of the second calling network and the connection status information meet the preset condition, the second calling network is selected.
In step S408, the calling terminal is instructed to call the called terminal through the second calling network.
By the method of the embodiment, the problem of call failure can be reduced as much as possible, so that the stability of a call network can be improved, and the user experience is improved.
In some embodiments, the first call network may be a 2G or 3G network, and the second call network may be a SIP (Session Initiation Protocol) network; alternatively, the first calling network may be a SIP network and the second calling network may be a 2G or 3G network. The first and second calling networks may also be other types of calling networks, as desired, and will not be described herein.
An embodiment of the method for selecting a calling network is described below with the first calling network being a 2G or 3G network and the second calling network being a SIP network.
Fig. 5 is a method of call network selection according to further embodiments of the present invention. As shown in fig. 5, the network selection method of this embodiment includes steps S502 to S512.
In step S502, the terminal a initiates a call to the terminal B through the 2G network of the mobile core network, and a call failure occurs.
Since the call fails through the 2G network, it can be considered to complete the call using the SIP network.
In step S504, the terminal a acquires the WiFi network M, N at the current location, and acquires information of the network M and connection status information connected to the correspondent node through the network M.
In step S506, the network M meeting the preset condition is selected as the network from which the terminal a originates a call.
In step S508, the call of terminal a is transferred to the application platform C via the mobile core network.
In step S510, the application platform C replaces the mobile phone number of the terminal B in the call forwarding relationship with the number of the SIP soft terminal D on the terminal B.
In step S512, the call initiated by terminal a is connected to the SIP soft terminal D on terminal B through the SIP network, so that the user of terminal B can obtain the call initiated by terminal a.
By the method of the embodiment, when the 2G or 3G network is unavailable, the call of the terminal can be continued through the SIP network, so that the called party can answer the call initiated by the calling party, the network stability is improved, and the user experience is better.
