In the implementation procedure that concrete network switches, network side can send switching command to terminal and make terminal switch to be switched network from current network.But, when terminal is in considerable scene, to be switched network of network quality can not for terminal bring message transmission rate more better than current network.Such as, present terminal is operated in the mobile communications network of LTE standard, but when LTE network signal strength signal intensity dies down the switching condition met from LTE to WCDMA time, the data service performance of the terminal in fact under LTE network is still better than WCDMA, now, for terminal, keep current LTE network and be only optimum selection.Give an example, according to statistical information, Reference Signal Received Power (the RSRP of LTE, ReferenceSignalReceivingPower)-95db to-110db is in, signal to noise ratio (SNR, SignalNoiseRatio), time interference is less, time data performance is still-80db than the received signal code power (RSCP, ReceivedSignalCodePower) of WCDMA, data performance is good.Although now meet the switching condition that LTE switches to WCDMA, WCDMA network cannot provide data service performance more better than LTE network for terminal.
In addition, when user is in all more weak situation of each standard network signal, such as when communal bathroom on the train that user is in high-speed motion or in building time, now, the signal quality of each standard network is all more weak, terminal can switch frequently under the network of different systems, but, because each standard network all can not provide good data service performance, therefore, switch the data processing performance that also cannot promote terminal frequently, so, also there is no need to switch the current residing network of terminal.
Except above two concrete conditions, under terminal is in other states a lot, do not need to switch current residing network yet, but because base station is only that the constant threshold index covered according to network of relations such as signal strength signal intensities carries out issuing of switching command, the judgement that whether cannot switch for situation residing for terminal reality.Therefore, for the technical scheme shown in Fig. 1, because terminal is after the switching command receiving network side transmission, the SOT state of termination according to self carries out decision-making to terminal switch network on one's own initiative, is not that the passive switching command that receives just switches.So the technical scheme shown in Fig. 1 can, when the switching command that network side frequently sends, avoid terminal to carry out network switching according to switching command passively, thus decreases electricity spent when terminal switches for network.
Exemplarily, in the present embodiment, the terminal's status information of the described terminal of described acquisition self, specifically comprises:
Described terminal obtains self positional information current by the navigation system such as GPS; And/or,
Described terminal obtains self movement state information current by the transducer such as acceleration transducer and horizontal gyro.
Understandably, above-mentioned positional information and movement state information all can characterize the current residing state of terminal, and except above-mentioned two kinds of information, those skilled in the art can also get the information for characterizing SOT state of termination of other types, and the present embodiment does not repeat this.
Correspondingly, in the mapping relations between the historical statistics state and accessing terminal to network state of terminal, the historical statistics state of terminal also can be the historical statistics value of above-mentioned positional information and movement state information.
Therefore, for above-mentioned positional information, alternatively, see Fig. 4, the embodiment of the present invention can also comprise:
S401: terminal is according to the historical position information by global position system GPS acquisition terminal of the activation frequency period preset;
S402: terminal is when the historical position information of acquisition terminal, and corresponding acquisition covers the first historic state of each standard network of terminal;
S403: terminal obtains the historic state of the first access network corresponding to terminal according to the first historic state of each standard network;
S404: the first mapping relations between the first historic state of terminal structure historical position information, each standard network and the historic state of the first access network.
In specific implementation process, terminal according to the activation frequency preset, periodically can be called GPS and obtains historical position information, be periodically depicted as event trace figure to historical position information; While the historical position information of acquisition terminal, on event trace, first historic state of each standard network covering terminal is obtained, the signal strength information etc. of such as network, and obtain the state of accessing terminal to network according to the first historic state of each standard network; Thus the first mapping relations constructed between historical position information, the first historic state of each standard network and the historic state of corresponding accessing terminal to network.
Thus, when the current residing position of terminal is in a certain position in historical movement track, terminal just according to state information and the first mapping relations measuring the current each standard network obtained, can determine whether terminal switches.
For aforementioned movement state information, alternatively, see Fig. 5, the scheme of the embodiment of the present invention can also comprise:
S501: terminal records the historical movement state of self in the time window preset, and obtains corresponding historical movement vector according to historical movement state computation;
S502: terminal is when recording the historical movement state of self, and corresponding acquisition covers the second historic state of each standard network of terminal;
S503: terminal obtains the historic state of the second access network corresponding to terminal according to the second historic state of each standard network;
S504: the second mapping relations between the second historic state of terminal structure historical movement vector, each standard network and the historic state of the second access network.
In specific implementation process, terminal can by the MEMS (micro electro mechanical system) such as acceleration transducer and horizontal gyro (MEMS in the time window preset, MicroelectroMechanicalSystem) transducer is obtained from the historical movement state in time window, and calculates corresponding historical movement vector; In time window.Second historic state of terminal to each standard network covering self obtains, and obtains the historic state of the second access network corresponding to terminal; Thus the second mapping relations constructed between historical movement vector, the second historic state of each standard network and the historic state of the second access network.
Thus, when the movement state information that terminal is current meets historical movement vector, terminal just according to state information and the second mapping relations measuring the current each standard network obtained, can determine whether terminal switches.
Present embodiments provide a kind of method of terminal switch network, after the switching command receiving network side transmission, terminal carries out decision-making to terminal switch network on one's own initiative according to the SOT state of termination of self, not that the passive switching command that receives just switches, thus when the switching command that network side frequently sends, avoid terminal to carry out network switching according to switching command passively, thus decrease electricity spent when terminal switches for network.
