Referring to the schematic flow sheet that Fig. 1, Fig. 1 are the systems of selection of the communication network that first embodiment of the invention provides, idiographic flow may include that
In step S101, when receiving instruction and carrying out the instruction conversed, according to the communication network that this instruction search is accessible.
It is to say, when terminal receive user's instruction carry out the instruction conversed time, according to the communication network for conversing that this instruction search terminal is accessible.
It is understood that in the embodiment of the present invention, accessible communication network is the network that good call voice can be provided to service for terminal. Such as, current 2G or 3G network, etc.
Preferably, before step S101, it is also possible to comprise the steps:
It is set into signal strength values during calling maintenance state.
It is to say, before step S101, it is also possible to set a signal strength values making terminal call enter calling maintenance state in advance, and this signal strength values is defined as preset signals threshold value. Also even the signal intensity of Current Communication Network network is lower than this preset signals threshold value, then the call of terminal room will enter calling maintenance state.
In step s 102, accessible communication network is determined present communications network, and sets up call based on present communications network.
It is to say, pick out one of them communication network in all accessible communication network for conversing searched, and after being defined as present communications network, communication network is set up the call of terminal room in this prior.
In a kind of possible embodiment, in accessible communication network, determine that present communications network may include that
Accessible communication network determines the communication network that signal is the strongest;
Communication network the strongest for signal is defined as present communications network.
It is understood that in this possible embodiment, be that communication network the strongest for signal is defined as present communications network.
Further, after set up the step of call based on present communications network, it is also possible to comprise the steps:
Whether detect the signal intensity of present communications network in real time lower than preset signals threshold value; Or,
According to predetermined space, whether the signal intensity of detection present communications network is lower than preset signals threshold value.
That is, after terminal sets up call based on present communications network, the signal intensity of present communications network can also be detected, to judge that whether the signal intensity of present communications network is lower than preset signals threshold value, and determine whether switching communication network according to judged result.
In step s 103, if detecting, the signal intensity of present communications network is lower than preset signals threshold value, then enter calling maintenance state, determine that signal intensity is not less than the spare communication network of preset signals threshold value in accessible communication network.
It is understandable that, signal strength values when having been set into calling maintenance state, and when this signal strength values is defined as preset signals threshold value, if detecting, the signal intensity of present communications network is lower than preset signals threshold value, then enter calling maintenance state, can specifically include: the signal intensity of present communications network is lower than described signal strength values if detecting, then enter calling maintenance state.
It should be noted that under calling maintenance state, the call of terminal room is suspended, but the connection between both call sides is to maintain on-state, say, that the call of terminal room can't be hung up. Therefore, calling maintenance state is entered, it is ensured that the call of terminal room is not interrupted.
That is, only when detecting that the signal intensity of present communications network is lower than preset signals threshold value, the call of terminal room just can enter calling maintenance state, and re-search in accessible communication network, determine that signal intensity is not less than the spare communication network of preset signals threshold value.
If it addition, detect that the signal intensity of present communications network is not less than preset signals threshold value, then terminal will not carry out searching net switching. Such as, if present communications network is 2G network, then when the signal intensity of 2G network is not less than preset signals threshold value, even if now terminal searching is better than 2G network to the signal of 3G network, it is switched to 3G network without by call.Thus decreasing the number of times that terminal call switches between heterogeneous networks, playing the guarantee unbroken effect of user's communication, also mitigating the load of network side simultaneously.

Preferably, if it is determined that in described accessible communication network, it is absent from signal intensity and is not less than the spare communication network of described preset signals threshold value, then now possibly cannot recover call, even if or recover call, its speech quality is also poor, then terminal can generate the information of network signal difference, to inform user.
From the foregoing, the system of selection of the communication network of embodiment of the present invention offer, when receiving instruction and carrying out the instruction conversed, determine present communications network and set up call in the accessible communication network searched. Only when the signal intensity of present communications network is lower than preset signals threshold value, just enter calling maintenance state, and search for and be switched to signal intensity and be not less than the spare communication network of preset signals threshold value. Therefore, the present invention can reduce the number of times that terminal switches between different communication networks, is effectively increased the speech quality of user. Meanwhile, the load of communication network side is alleviated.
Second embodiment
Method described by first embodiment, will be described in further detail for mobile phone the system of selection of communication network below.
Referring to the schematic flow sheet of the system of selection of the communication network that Fig. 2, Fig. 2 provide for second embodiment of the invention, idiographic flow may include that
In step s 201, setting mobile phone and enter signal strength values when calling maintenance state, this signal strength values is defined as preset signals threshold value by mobile phone.
That is, it is possible to set a signal strength values making mobile phone enter calling maintenance state in advance, and this signal strength values is defined as preset signals threshold value. Namely in mobile phone communication process, if the signal intensity of present communications network is lower than preset signals threshold value, then the call between mobile phone will enter calling maintenance state.
It should be noted that under calling maintenance state, the call between mobile phone is suspended, but the connection between both call sides is to maintain on-state, say, that the call between mobile phone can't be hung up. Therefore, calling maintenance state is entered, it is ensured that the call between mobile phone is not interrupted.
In step S202, when mobile phone receive instruction carry out the instruction conversed time, mobile phone is according to the accessible communication network of this instruction search.
It is to say, when mobile phone receive user's instruction carry out the instruction conversed time, according to the communication network for conversing that this instruction searching handset is accessible.
It is understood that in this embodiment, accessible communication network is the network that good call voice can be provided to service for mobile phone. Such as, current 2G or 3G network, etc.
In step S203, present communications network determined by mobile phone in accessible communication network, and sets up call based on present communications network.

In a kind of possible embodiment, described in accessible communication network, determine present communications network, it is possible to including:
Accessible communication network determines the communication network that signal is the strongest;
Communication network the strongest for signal is defined as present communications network.
It is understood that in this possible embodiment, be that communication network the strongest for signal is defined as present communications network. Such as, if in accessible communication network, the signal of 2G network is the strongest, then 2G network is just defined as present communications network, and sets up the call between mobile phone on 2G network, etc.
In alternatively possible embodiment, it is also possible to take other method to determine present communications network. Such as, when the signal intensity of 3G network is close to 2G network, it is possible to by the mode set, present communications network is preferentially defined as 3G network, this is because the speech quality of 3G network is better, sound spectrum is wider, etc.
It is understood that in order to ensure speech quality, it is possible to after setting up the call between mobile phone, closing hand phone continues search for the function of the communication network that can be accessed by. Namely call is locked in present communications network by mobile phone, without continuing search for the communication network that other signal becomes higher.
In step S204, whether the signal intensity of mobile phone detection present communications network is lower than preset signals threshold value.
It is to say, after setting up call, it is necessary to the signal intensity of detection present communications network, whether the signal intensity to judge present communications network decays to lower than preset signals threshold value.
Such as, if present communications network is 2G network, then whether step S204 can particularly as follows: detects the signal intensity of current 2G network lower than preset signals threshold value.
In possible embodiment, whether the signal intensity of described mobile phone detection present communications network is lower than preset signals threshold value, can be that mobile phone detects the signal intensity of present communications network in real time whether lower than preset signals threshold value, can also being mobile phone according to predetermined space, whether the signal intensity of detection present communications network be lower than preset signals threshold value.
It is understood that this predetermined space can be preset by user or mobile phone manufacturer, such as predetermined space can be set to 3 seconds, 5 seconds, etc., it is not specifically limited herein.
In step S205, mobile phone enters calling maintenance state, determines that signal intensity is not less than the spare communication network of preset signals threshold value in accessible communication network.
That is, only when detecting that the signal intensity attenuation of present communications network is to lower than preset signals threshold value, mobile phone just can enter calling maintenance state, to prevent dropped calls, and in accessible communication network, determine that signal intensity is not less than the spare communication network of preset signals threshold value.
Such as, in communication process, if detecting, the signal intensity of current 2G network is lower than preset signals threshold value, then mobile phone enters calling maintenance state, to prevent dropped calls, and in accessible communication network, determine that signal intensity is not less than the spare communication network of preset signals threshold value, such as 3G network etc.
If detecting, the signal intensity of present communications network is not less than preset signals threshold value, then continue the call between mobile phone on present communications network.
Such as, if detecting, the signal intensity of current 2G network is not less than preset signals threshold value, then continue the call between mobile phone on 2G network.
In step S206, spare communication network is defined as present communications network by mobile phone, and indicates recovery call.
If it is to say, define signal intensity in accessible communication network to be not less than the spare communication network of preset signals threshold value, then in step S206, spare communication network is defined as present communications network by mobile phone, and indicates recovery call.
Such as, if determining in accessible communication network, the signal intensity of 3G network is not less than preset signals threshold value, then 3G network can be defined as present communications network, and by original 2G network, call is switched to 3G network carries out.
It is understood that spare communication network to be defined as present communications network, and indicate recovery call after, it is still desirable to detection present communications network signal intensity whether lower than preset signals threshold value, as described in step S204, repeat no more herein. Such as, call being switched to after 3G network carries out by original 2G network, whether the signal intensity of detection 3G network is still needed to lower than preset signals threshold value.
Further, however, it is determined that go out in described accessible communication network, it is absent from signal intensity and is not less than the spare communication network of described preset signals threshold value, then generate the information of network signal difference.
Such as, now the signal of 2G and 3G network is below preset signals threshold value, illustrates that the signal of now 2G and 3G network is all very poor, then can generate the information of network signal difference, and ask the user whether to continue calling maintenance state. Now user can select to continue calling maintenance state, it is also possible to kill-call, etc.
From the foregoing, the system of selection of communication network that the embodiment of the present invention provides, when mobile phone receive instruction carry out the instruction conversed time, determine present communications network and set up call in the accessible communication network searched. Only when the signal intensity of present communications network is lower than preset signals threshold value, mobile phone just enters calling maintenance state, and searches for and be switched to signal intensity and be not less than the spare communication network of preset signals threshold value. Therefore, the present invention can reduce the number of times that terminal switches between different communication networks, is effectively increased the speech quality of user. Meanwhile, the load of communication network side is alleviated.
