Embodiment
For the object, technical solution and advantage of the application are more clearly understood, develop simultaneously embodiment referring to the drawings, right
The application is described in further detail.
The UE positional informations in V2V networks are reported in order to realize, this application provides reported in two kinds of V2V networks
The method of UE positional informations, is described in detail separately below.
The first preferred approach：
1st step：UE obtains from eNB：ENB global positioning system (GPS) longitude and latitude and zone granularity；Preferably, can
To obtain the granularity of eNB GPS longitudes and latitudes and zone in system information block (SIB) message for being broadcasted from eNB；
2nd step：UE is divided and numbered to zone according to the GPS longitudes and latitudes of the eNB and zone granularity；
3rd step：UE measures UE GPS longitudes and latitudes by the GPS device of itself；
4th step：UE determines the UE institutes according to the GPS longitudes and latitudes of the result for being divided and being numbered to zone, and UE
Zone numberings, and report eNB.
Wherein, the 1st step and the 3rd step do not have point of strict precedence.
In above-mentioned 2nd step, UE is divided and numbered to zone according to the GPS longitudes and latitudes of the eNB and zone granularity
Specifically include：
Reference axis is established as coordinate center using eNB GPS longitudes and latitudes, zone granularity is designated as t, since coordinate center
Four quadrants are respectively divided into the square area that the length of side is t；
Carry out first round numbering：Any selection one is numbered as zone1 from following 4 square areas：Horizontal seat
Mark and ordinate are t, and abscissa is that t ordinates are-t, and abscissa is that-t ordinates are-t, and abscissa is that-t ordinates are t；
Since zone1, according to remaining 3 square areas are numbered clockwise or counterclockwise；
Carry out the second wheel numbering：Appoint in adjacent 8 square areas of 4 square areas from being numbered with the first round
Meaning selection one is numbered as zone5, since zone5, according to clockwise or counterclockwise to remaining 7 squares
Region is numbered；
By that analogy, the n-th wheel numbering is carried out：4* (2* (n-1) -1) square area from the (n-1)th wheel numbering is adjacent
4* (2n-1) individual square area in any selection one numbered as zone (4* (n-1) 2+1), from zone (4* (n-1)
2+1) start, according to -1 square area of remaining 4* (2n-1) is numbered clockwise or counterclockwise.
Below by citing, the first above-mentioned preferred approach is illustrated.
ENB at least carries following two parameters in the SIB message of broadcast：ENB global positioning system (GPS) longitude and latitude
With zone granularity.
Such as：GPS longitudes and latitudes are：East longitude 39.9158056687, north latitude 116.3831872665；
Zone granularity is 50 meters.
First, UE measures UE GPS longitudes and latitudes by the GPS device of itself.
Then, after UE receives the granularity of the longitude and latitude that eNB issues and zone, according to eNB longitude and latitude and zone grain
Degree is divided and numbered to zone according to the citing of following two method for numbering serial, and where obtaining the GPS longitudes and latitudes of itself
Zone is numbered, and reports eNB.
Zone method for numbering serial citing 1：
First, first round numbering is carried out：It is 50 meters of 50x50 by abscissa and ordinate using base station as coordinate center
Square region Field Number be zone1, be 50 meters by abscissa, ordinate is -50 meters of zone number according to clockwise
For zone2, by that analogy, according to clockwise direction number consecutively to zone4, as shown in Figure 1；
Then, the second wheel numbering is carried out：Second wheel numbering since the first round numbering last region above by
Carried out according to clockwise direction, that is, since the zone5 shown in Fig. 1, area size is still 50x50 rice, is continued according to suitable
Clockwise numbering arrives zone16；
Third round numbering is carried out since the top in last region of the second wheel numbering according to clockwise direction, also
It is since the zone17 shown in Fig. 1, area size is still 50x50 rice, is continued according to numbering clockwise to 36；
By that analogy later.
Zone method for numbering serial citing 2：
First, first round numbering is carried out：It it is 50 meters by ordinate using base station as coordinate center, abscissa is -50 meters
50x50 square numbering is zone1, is zone2 by the square region Field Number that abscissa and ordinate are 50 meters, with this
Analogize, according to clockwise direction number consecutively to zone4, as shown in Figure 2；
Then, the second wheel numbering is carried out：Second wheel is numbered from the pros using the zone1 upper left corner as the 50x50 in the lower right corner
Shape region proceeds by numbering, zone5 as depicted, zone16 is arrived according to clockwise direction numbering；
By that analogy later.
In two kinds of coding methods enumerated above, illustrated exemplified by clockwise, in actual applications, can also
According to counter clockwise direction carry out, also, each round numbering direction be it is independent, can be by the way of clockwise or counterclockwise
Carry out, as long as UE and the coding method of eNB sides are consistent.
Second of preferred approach：
ENB broadcasts the GPS information of several hotspot locations in SIB message, and UE is according to the GPS informations of these hotspot locations
Judge itself distance with these hotspot locations, and report the numbering of closest focus.
For example eNB broadcasts the GPS information of 5 focuses, numbering is respectively：
Focus 1 (east longitude 39.9158056687, north latitude 116.3831872665)；
Focus 2 (east longitude 39.9158056458, north latitude 116.3831872459)；
Focus 3 (east longitude 39.9158056987, north latitude 116.383187235)；
Focus 4 (east longitude 39.9158056512, north latitude 116.3831872697)；
Focus 5 (east longitude 39.9158056125, north latitude 116.38318724423).
UE measures the GPS longitudes and latitudes of itself by the GPS device of itself, then more above-mentioned 5 positional informations, find out with
The numbering of itself relatively nearest focus reports eNB.
The preferred embodiment of the application is the foregoing is only, not limiting the application, all essences in the application
God any modification, equivalent substitution and improvements done etc., should be included within the scope of the application protection with principle.
