In conjunction with Fig. 3, the present embodiments relate to the information exchanges between car-mounted terminal and two network elements of server of network side, wherein the server of network side is specifically V2X server.Detailed process of the invention is as follows:
201, car-mounted terminal obtains V2X message；
Car-mounted terminal obtains the V2X message for needing to broadcast, which, which can be, is obtained by car-mounted terminal itself generation or car-mounted terminal from extraneous other equipment.Wherein obtaining V2X message from extraneous other equipment may is that the V2X message for receiving other car-mounted terminals, other mobile devices or base station and sending.
202, car-mounted terminal determines ECGI list (that is: ECGI list) according to V2X message；
When there is the generation of V2X message, car-mounted terminal determines the ECGI list that the message needs to forward according to V2X message, ECGI list indicates the cell list that the V2X needs to be forwarded to, wherein, ECGI is by public land mobile network (English: Public Land Mobile Network, it referred to as: PLMN) is formed with cell ID (Cell Identity), for one cell of overall identification in the plmn.
Broadcasting area ECGI list may include: the serving cell mark (Identity, ID) of the car-mounted terminal；It can also include the cell ID for the adjacent area that the car-mounted terminal can listen to；It can also include the gravity treatment adjacent area configured in the received system message of UE.Wherein, the gravity treatment adjacent area configured in system message includes the cell ID for the homogeneous-frequency adjacent-domain that the car-mounted terminal is obtained from the system information block SIB4 in system message；Can also include The cell ID for the alien frequencies adjacent area that the car-mounted terminal is obtained from the system information block SIB5 in system message.
The schematic diagram for the cell that may include in ECGI list is as shown in figure 4, A indicates the current resident serving cell of car-mounted terminal；When car-mounted terminal resides in serving cell A, car-mounted terminal can listen to the system message of cell, and multiple system information block SIB, including SIB4 and SIB5 are carried in system message.Wherein, the neighboring BS information of the co-frequency cell LTE gravity treatment is contained in SIB4, specifically includes neighboring cell list, the information such as adjacent area blacklist；The neighboring BS information of the alien-frequency district LTE gravity treatment is contained in SIB5, specifically includes neighboring cell list, carrier frequency, the information such as cell reselection priority.C indicates the homogeneous-frequency adjacent-domain that car-mounted terminal is obtained from the SIB4 of system message, and D indicates the alien frequencies adjacent area that car-mounted terminal is obtained from the SIB5 of system message.B indicates the adjacent area that car-mounted terminal can listen to, in addition, car-mounted terminal obtains in alien frequencies adjacent area from the homogeneous-frequency adjacent-domain and SIB5 obtained in SIB4, some adjacent areas are that car-mounted terminal cannot listen to, therefore, the BC in Fig. 4 indicates car-mounted terminal from the homogeneous-frequency adjacent-domain obtained in SIB4, the adjacent area that car-mounted terminal can listen to, BD indicates car-mounted terminal from the alien frequencies adjacent area obtained in SIB5, the adjacent area that car-mounted terminal can listen to.
Specifically, car-mounted terminal can determine the range of ECGI list, different types of V2X message according to the type of V2X message, important degree is different, thus broadcasting area is also different, common insignificant type of message, broadcasting area is small, important type of message, and broadcasting area is big.
Such as: if it is the relevant message of road safety (speed, position, the message of vehicle etc) of common periodicity sending, then ECGI list only includes the serving cell ID of car-mounted terminal；It then ECGI list had not only included the serving cell ID of car-mounted terminal, but also include the cell ID for the adjacent area that car-mounted terminal can listen to if it is insignificant message (such as: the message of traffic congestion etc)；It (collides if it is the relevant message of road safety of event triggering, traffic control), so ECGI list may just the serving cell ID comprising car-mounted terminal and all adjacent areas cell ID (the cell ID including the adjacent area that above-mentioned car-mounted terminal can listen to, the cell ID of the homogeneous-frequency adjacent-domain obtained from SIB4, and the cell ID of alien frequencies adjacent area obtained from SIB5).
A kind of optional implementation are as follows: system gives the good broadcasting area preset value of different types of V2X message sets, and the V2X message that car-mounted terminal can according to need broadcast obtains default broadcasting area from the preset value of system.
It should be noted that car-mounted terminal other than determining ECGI list according to the type of message of V2X message, can also be determined according to the other factors of V2X message, and such as: it can be according to the V2X message Geographical location in content determines ECGI list, such as: road damages road hazard condition warning applications message can ECGI list in 5 kilometer range of geographical location that only broadcast occurs to road damage.Or car-mounted terminal can determine ECGI list in combination with the relevant several factors of the V2X message content, and such as: ECGI list can be determined in conjunction with the Time To Event in the type of message of V2X message, the geographical location that the message occurs, the V2X message.
203, car-mounted terminal sends the V2X message and ECGI list to server.
