Wherein, when described first matching result shows that described work at present system is not mated with described present type of service, described first judged result shows that needs switch described work at present system.
Embodiment 1, when at least one parameter is present type of service:
Based on present type of service, judge whether the work at present system of LTE communication system matches with described present type of service, obtain the first matching result, because TD-LTE system is more suitable for non-symmetrical spectrum, symmetrical spectrum is more suitable for FDD-LTE system, therefore, TD-LTE system mates with the first type of service (following behavior master) or the second type of service (above behavior master) that use can be better, and FDD-LTE system and the 3rd type of service (up-downgoing is symmetrical) match also better, therefore, what the first matching result characterized is exactly whether current work system matches with present type of service.Certainly, after obtaining the first matching result, base station can judge whether will switch the work at present system of LTE communication system based on the first matching result, and obtain the first judged result, only have when showing that described work at present system is not mated with described present type of service when described first matching result, the first judged result of acquisition just shows that needs switch described work at present system.Such as, when work at present system is TD-LTE system, and the type of service between mobile phone and base station is upper behavior master, or when lower behavior is main, the first matching result then obtained shows that work at present system and present type of service match, thus the first judged result obtained just shows not need to switch work at present system, base station continues to carry out the communication with mobile phone terminal with current TD-LTE system.
Visible, in the embodiment of the present application owing to adopting the present type of service between Real-time Obtaining terminal and base station, then by judging whether the current communication networks of LTE matches with this present type of service, if do not mate the technological means just carrying out switching, achieve the technique effect that the type of service of base station in real time between basis and terminal is switched current communication networks.
Further, described step S2, specifically comprises:
Based on described first kinematic parameter, judge whether the work at present system of described LTE communication system matches with described first kinematic parameter, obtains the second matching result;
Based on described second matching result, judge to determine whether to switch the work at present system of described LTE communication system, obtain the first judged result;

Embodiment 2, when at least one parameter is for during when the first kinematic parameter:
Based on the first kinematic parameter of mobile phone, judge whether the work at present system of LTE communication system matches with described first kinematic parameter, obtain the second matching result, what the second matching result characterized is exactly that the first whether current with mobile phone kinematic parameter of current work system matches.Because TD-LTE system is more suitable for communication mode when terminal remains static, FDD-LTE system is the communication mode that is kept in motion of appropriate terminal more, and such as, mobile phone moves at a slow speed with the speed of 30Km/hour.Therefore, after obtaining the second matching result, base station can judge whether will switch the work at present system of LTE communication system based on the second matching result, and obtain the first judged result, only have when showing that described work at present system is not mated with the first kinematic parameter of described mobile phone when described second matching result, the first judged result of acquisition just shows that needs switch described work at present system.
Visible, in the embodiment of the present application owing to adopting the kinematic parameter of Real-time Obtaining terminal, then by judging whether the current communication networks of LTE matches with the mobile status of terminal, if do not mate the technological means just carrying out switching, achieve the technique effect that base station is switched current communication networks according to the mobile status of terminal in real time.
Further, described step S2, specifically comprises:
Based on described present type of service and described first kinematic parameter, judge whether the work at present system of described LTE communication system matches with described present type of service and described first kinematic parameter, obtain the 3rd matching result;
Based on described 3rd matching result, judge to determine whether to switch the work at present system of described LTE communication system, obtain the first judged result;
Wherein, when described 3rd matching result shows that described work at present system is not mated with described present type of service and described first kinematic parameter, described first judged result shows that needs switch described work at present system;
When described 3rd matching result shows that described work at present system is not only mated with described present type of service, and the first priority corresponding to described present type of service is when being greater than the second priority corresponding to described first kinematic parameter, described first judged result shows that needs switch described work at present system;
When described 3rd matching result shows that described work at present system is not only mated with described first kinematic parameter, and the second priority corresponding to described first kinematic parameter is when being greater than the first priority corresponding to described present type of service, described first judged result shows that needs switch described work at present system.
Embodiment 3, when at least one parameter be present type of service and the first kinematic parameter time:
Describe respectively in two embodiments above system only based on terminal and base station between type of service, or the first kinematic parameter of terminal judges whether the mode that will switch work at present system, specifically introduce in the present embodiment and to come together the process that determines whether to switch work at present system based on present type of service and the first kinematic parameter.
When every one section of preset time period, obtain the present type of service between mobile phone and base station, and after the first kinematic parameter of mobile phone, based on two parameters, judge whether the work at present system of LTE communication system matches with described present type of service and the first kinematic parameter respectively, obtain the 3rd matching result, then judge whether to switch the work at present system of LTE based on the 3rd matching result, obtain the first judged result.Here, the 3rd matching result has that the work at present system of three kinds of result: LTE all matches with present type of service and the first kinematic parameter, the work at present system of LTE is not mated with present type of service and the first kinematic parameter, in the work at present system of LTE and present type of service and the first kinematic parameter one matches.If when the 3rd matching result shows that described work at present system is not mated with described present type of service and described first kinematic parameter, then the first judged result shows that needs switch described work at present system, such as, when work at present system is TD-LTE system, and present type of service is above behavior master and mobile phone when remaining static, illustrate that work at present system and present type of service and the first parameter all match, therefore do not need to switch work at present system.If when the 3rd matching result shows that work at present system does not only match with one of them parameter, at this moment also to determine whether will switch work at present system according to the height of two parameters and work at present system matches degree, namely compare the priority of two parameters, priority about two parameters and work at present system matches degree can be preset as required by designer, as shown in table 1, provide the matching result form that a present type of service and the first kinematic parameter and work at present system match in the embodiment of the present application:
Table 1
Known by table 1, in the embodiment of the present application preset when the first kinematic parameter of mobile phone is lower than 30km/hour, no matter just the translational speed of mobile phone is how many, matching result is only determined by type of service, when type of service is upper behavior master, or during the non-symmetrical service of lower behavior master, adopt TD-LTE system; When type of service is the type of service of up-downgoing symmetry, adopt FDD-LTE system.When the first kinematic parameter of mobile phone is between 30km/hour to 60km/hour, and when type of service is non-symmetrical service, matching result for adopting TD-LTE system, otherwise adopts FDD-LTE system.When the first kinematic parameter of mobile phone is for being greater than 60km/hour, no matter type of service is symmetrical or asymmetric, matching result all only adopts FDD-LTE system.
Visible, in the embodiment of the present application, owing to adopting the real time business type after one section of Preset Time just between acquisition terminal and base station, and the kinematic parameter of terminal, then judge whether these parameters match with current work system, and matching result is determined by the parameter that priority is high, the technological means of work at present system is switched according to matching result, achieve the technique effect that jointly can adjust the communication pattern of LTE in real time according to the traffic carrying capacity of transmission and the situation of movement of terminal, further increase and communication system is switched to the accuracy with optimal system.
In the embodiment of the present application, mobile phone is needed to coordinate with base station two side to the switching of communication system, such as, the main function of mobile phone is the state reporting self, such as, the type of service of current transmission or kinematic parameter, also will inform the band limits that community self is supported and standard simultaneously.And statistics effect is played in base station, base station, according to Intra-cell mobile phone overall quantity and business, is determined to adopt TD-LTE or FDD-LTE.
Switch back and forth between TD-LTE and FDD-LTE for preventing base station and mobile phone, base station and face the transmission power intensity that cell base station can report according to mobile phone, the movement velocity that the intensity of the mobile phone transmission power that RSSI and base station receive and mobile phone gsensor calculate judges that mobile phone needs how long to stop in community, have the Intra-cell of how many users for oneself, if majority is to move (automobile passes through community), that fdd is first-selected, if and majority is stopped in (coffee shop or market), just based on TD-LTE.
Simply describe base station with a concrete enforcement below and estimate that the time that judgement mobile phone stops is mode how long: a mobile phone is in A community, advance to B community, when being in A core space, B can not receive the signal of mobile phone, when A constantly advances, during close to AB cell edge, mobile phone finds the signal weaker from A community, and the base station of A also can perceive this change, and B community receives the signal of A simultaneously, and continuous grow, know that mobile phone will leave A and arrive B; As occurred, A receives mobile phone signal and dies down, but B does not detect that the situation that mobile phone signal strengthens, mobile phone are in the weak place of signal, and as elevator, underground garage, therefore, judges how long mobile phone stops.
S3: when described first judged result shows that needs switch described work at present system, generate and perform the first switching command, controlling described work at present system and be switched to second system from the first system described TD-LTE communication system and described FDD-LTE communication system.
Further, when work at present system is specially described TD-LTE communication system, described step S3, is specially:
