Wave condition mapping is constructed portion 307 and is constructed wave condition mapping according to the information of the electric wave information receiving and radio section.About the method for constructing, will be described hereinafter.
In addition, in the example of Fig. 5, the information of the radio section 2 that the notified wireless terminal PS1 of resource-area judging part 303Jiang Cong department of resource management 304 is being used is constructed portion 307 to wave condition mapping and is transmitted, supposing to be passed to wave condition mapping from resource-area judging part 303, to construct the information of portion 307 be only the information of wireless terminal PS1, and portion 307 is constructed in wave condition mapping also can inquire the information of the radio section 2 that this wireless terminal PS1 used in addition to department of resource management 304.That is, the information that portion 307 keeps the radio section 2 of electric wave information that wireless terminal PS1 now receive and utilization is constructed in wave condition mapping, but can adopt mode arbitrarily before this.
Fig. 6, Fig. 7, Fig. 8 show the example of the timing of wireless terminal notice electric wave information.
Fig. 6 notifies the example of the situation of electric wave information at a certain time interval from wireless terminal.In the example of Fig. 6, due to entire system carried out synchronously, wireless terminal PS and radio control section S can hold the timing of notice electric wave information, so radio control section S can identify the timing of the data that receive electric wave information.
It is the indication of wave condition notice that Fig. 7 shows the message that radio section 2 sends to wireless terminal PS the notice be used to indicate electric wave information at a certain time interval, receives the example of the wireless terminal PS of wave condition notice indication sends situation from electric wave information to radio section 2.In the example of Fig. 7, even if wireless terminal PS does not need to obtain and synchronize with entire system, synchronous consistent due to timing and the system of notice, so radio control section S can identify the timing of the data of reception electric wave information.
Fig. 8 be wave condition lower than or higher than predefined threshold value in the situation that, wireless terminal PS is the example to the situation of radio control section S notice by electric wave information.Threshold value is not only defined in one, also can set a plurality of.In the example of Fig. 8, because radio control section S does not know when receive electric wave information, wave condition notice judging part 306 shown in above-mentioned Fig. 5 can judge whether it is electric wave information according to the content of data, or can determine for notifying the resource-area of electric wave information to use on entire system ground.
Fig. 9 shows an example of being constructed the wave condition mapping of portion's 307 making by wave condition mapping.As described above, according to process before this, to wave condition mapping, construct that the wave condition that wireless terminal PS receives, positional information have now been given by portion 307 and the information of the radio section 2 that now utilizes.
The mapping of wave condition in the example of Fig. 9 is constructed in example, first so that the radio section that grand diversity has been moved is wave condition mapping is constructed by unit.The mensuration number of times etc. that records the wave condition in this place by each latitude, longitude and up to the present given this place in the mapping of each wave condition.Measure number of times is used in the average grade of calculating wave condition.For example, in the situation that nearest 100 times average calculated in hope, by seasonal effect in time series order, keep 100 wave conditions.
In the example of the table shown in Fig. 9 (a), show each latitude while utilizing radio section A and radio section B to make grand diversity action, the wave condition of longitude, in the example of the table illustrating at Fig. 9 (b), show each latitude while utilizing radio section A and radio section C to make grand diversity action, the wave condition of longitude.Like this, for example, place at latitude 45.5 degree, longitude 123.3 degree, between wireless terminal PS and radio section B, exist and hinder thing, can easily hold, with utilizing radio section A and radio section B, the situation of grand diversity action is compared, utilized radio section A and radio section C to make the situation of grand diversity action more can improve wave condition.This means in the situation that wireless terminal being made to the action of grand diversity, can find instantaneously the combination of best radio section, for the wireless terminal of high-speed mobile etc., especially can bring into play effect.
Figure 10 shows the display case of the wave condition mapping of constructing as shown in Figure 9 above.The configuration of 1001 expression radio section A, B, C in Figure 10, display case when 1002 expressions utilize radio section A and radio section B to make grand diversity action in Figure 10, display case when 1003 expressions utilize radio section A and radio section C to make grand diversity action in Figure 10.If dotted portion in 1002,1003 in concern Figure 10 has knownly improved gain in the situation that using radio section A and radio section C, wave condition is improved.Like this, by vision, show that wave condition shines upon, can judge at once and in desirable place, use which (one or more) radio section to make grand diversity action can improve efficiently wave condition.
In addition, in the example of Fig. 9, positional information has been utilized latitude, longitude, but in addition also datum mark can be set, and utilizes the positional information apart from the distance and bearing in this place etc., so long as means that can unique decision position, no matter positional information is that what kind can.In addition, the granularity of positional information is arbitrarily in system, in the situation that make careful wave condition mapping set position information meticulously.In addition, the mapping of each wave condition does not need the position of storage system integral body, only keeps the information in the region that corresponding radio section covers, by reducing the capacity of the storage medium of use like this.
Thereby Figure 11 is an example that keeps wave condition mapping to keep in more detail electric wave state by bringing sliced time.For example, larger with night traffic quantitative changeization by day, wave condition in different situation, shines upon by making a plurality of wave conditions mappings rather than a wave condition largely, can construct more high-precision wave condition mapping.The quantity of 1 per day wave condition mapping of constructing also can be by system arbitrary decision.Like this, by bringing sliced time a plurality of wave conditions of making to shine upon, can use best radio section make grand diversity action according to time band, and then improve efficiently wave condition.
In addition, although understand some execution modes, but these execution modes are only suggested as an example, and its object does not lie in restriction scope of invention.These new execution modes can be implemented with other variform, in the scope of main idea that does not depart from invention, can carry out various omissions, displacement, change.These execution modes and distortion thereof are also contained in scope of invention and main idea, and are also contained in the invention and equal scope thereof of recording in claims.
