Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
As shown in Figure 2, the flow chart of the position information transmitting method that Fig. 2 mentions for one embodiment of the invention, this method comprises:
Step S10 confirms the positional information of user terminal current region according to the user terminal call signal;
In the present embodiment; On the distance of advancing of user terminal a plurality of base stations are installed, when user terminal sends call signal, nearest base station, distance users terminal will receive this call signal; And sending it to the positional information transfer device, the positional information transfer device is a base station controller BSC here.Base station controller BSC can be confirmed the regional location at the current place of user terminal through the position of base station.
Step S20 analyzes the wavelength or the frequency change situation of the said user terminal call signal receive, judges the direction of advance of this user terminal;
Present embodiment is wavelength or a frequency change situation of utilizing the user terminal call signal that the doppler principle analysis receives, with the direction of advance at judges terminal.Doppler principle is meant that the wavelength of object radiation is because wave source and observer's caused by relative motion changes.When the observer the motion wave source the place ahead the time, the ripple that the observer receives is compressed, it is shorter that wavelength becomes, it is higher that frequency becomes; When wave source when back of observer in motion, the ripple that the observer receives can produce opposite effect, and it is longer that wavelength becomes, and it is lower that frequency becomes.The speed of wave source is high more, and the effect that is produced is big more, according to the situation of change of wavelength or frequency, can extrapolate the direction of motion and the motion speed degree of wave source with respect to the observer.Base station controller BSC utilizes the call signal that user terminal sent of doppler principle analysis in going with respect to the wavelength of base station or the situation of change of frequency; With the judges terminal is to advance to the direction near the base station, or to the direction running away from the base station.When user terminal was shifted to the base station at a high speed, the base station was positioned at call signal wave source the place ahead, and the call signal ripple is compressed, and it is shorter that wavelength becomes, and it is higher that frequency becomes; When user terminal left the base station at a high speed, the base station was positioned at call signal wave source rear, and it is longer that wavelength becomes, and it is lower that frequency becomes.
Step S30 according to the direction of advance of said user terminal, when user terminal is about to go to next zone by current region, reports next regional positional information.
In the present embodiment; Base station controller BSC is about to the zone of arrival according to the direction of advance judges terminal of user terminal; I.e. user terminal region when call setup; And the regional location that user terminal be about to arrive is reported to network application layer (like moving exchanging center MSC), guarantee that network application layer commences business according to correct zone position information.
As shown in Figure 3, Fig. 3 is the flow chart of step S20 in the position information transmitting method shown in Figure 2.Step S20 specifically comprises:
Step S21 analyzes the wavelength of the said user terminal call signal that receives or the situation of change of frequency;
Step S22 during elongated or frequencies go lower, judges that said user terminal goes towards next zone when the wavelength of said call signal.
Present embodiment utilizes doppler principle to measure user terminal call signal ripple situation of change, and promptly user terminal is with respect to the direction of motion of base station.When user terminal was shifted to the base station at a high speed, the base station was positioned at call signal wave source the place ahead, and the call signal ripple is compressed, and it is shorter that wavelength becomes, and it is higher that frequency becomes; When user terminal left the base station at a high speed, the base station was positioned at call signal wave source rear, and it is longer that wavelength becomes, and it is lower that frequency becomes.Base station controller BSC can be judged the direction that user terminal advances through to the wavelength of call signal or the analysis of frequency, and then definite user terminal is about to the regional location of arrival.When the travel direction of user terminal is during towards next zone; Explain that user terminal just preparing to get into next zone from current region; For guaranteeing to call out between user terminal and the correct zone, need in advance that next is regional positional information be reported to network application layer; When the travel direction of user terminal during for last zone dorsad; Explain that then user terminal has entered into next zone; Be that current region is next zone; Then direct positional information with the user terminal current region is reported to network application layer, commences business according to correct zone position information to guarantee network application layer.
As shown in Figure 4, Fig. 4 is the flow chart of position information transmitting method among another embodiment, and this method embodiment comprises the step of boundary position judgment.Also comprise step after the step S10:
Step S40 judges whether said user terminal is in current region and intersection that next is regional; If not, execution in step S41 then; If, execution in step S20 then;
Step S41 reports the positional information of current region.
In the present embodiment; When user terminal location during not at two regional intersections; User terminal is called out to successfully setting up from sending call signal, and user terminal can not leave current region, so can omit the step that the user terminal direction of advance is judged; Shortened on the zone position information and called time, reported more timely; When user terminal location during at two regional intersections; User terminal possibly get into next zone from last zone; Therefore need judge the regional location that user terminal is about to get into, commence business according to correct zone position information to guarantee network application layer.
