Fig. 1 is the flow chart of the method for directional transmissions message described in the application's embodiment, and as shown in Figure 1, described method can comprise:
S100: one receiving equipment receives a message, carry in described message the transmitting apparatus of described message geographical location information and with at least one party to corresponding transmission jump number;
S120: according to the geographical location information of the transmitting apparatus of described message and the geographical location information of described receiving equipment, determine the offset direction of described receiving equipment compared to the transmitting apparatus of described message;
S140: at least according to described offset direction and described with at least one party to corresponding transmission jump number, determine whether to forward described message.
The method of the directional transmissions message described in the embodiment of the present application, by carry in message with at least one party to corresponding transmission jump number, transmission of news scope can be limited within certain scope.Avoid too much the taking of Internet resources, make the transmission of message more targeted, improve efficiency of transmission.
Exemplary, in an embodiment of the present invention, described at least one party is to being direction, 4, east, south, west, north, also can be due east, due south, Zheng Xi, Zheng Bei, the southeast, northeast, southwest, direction, 8, northwest, or can also be 1 o'clock direction, 2 o'clock direction ... 12 directions such as 12 o'clock direction etc.Certainly, can also be self-defining any one or more direction, embodiments of the invention be not construed as limiting this.
In an optional execution mode, as shown in Figure 2, in above-mentioned S140 at least according to described offset direction and described with at least one party to corresponding transmission jump number, determine whether to forward described message, can comprise:
S141: determine described offset direction be whether described at least one party in one;
S142: in response to described offset direction be described at least one party in one, at least according to the transmission jump number corresponding with described offset direction, determine whether to forward described message.
Such as, if carry transmission jump number corresponding with direction, 4, east, south, west, north respectively in message, and described receiving equipment is east compared to the offset direction of described transmitting apparatus, that is: receiving equipment is positioned at the east of transmitting apparatus, then at least can, according to the transmission jump number corresponding with east orientation of carrying in message, determine whether to forward described message.
In another optional execution mode, as shown in Figure 3, in above-mentioned S140 at least according to described offset direction and described with at least one party to corresponding transmission jump number, determine whether to forward described message, can also comprise:
S143: in response to described offset direction be not described at least one party in any one, do not forward described message.
Such as, if carry transmission jump number corresponding with east, south, direction, 3, north respectively in message, and described receiving equipment is west compared to the offset direction of described transmitting apparatus, that is: receiving equipment is positioned at the east of transmitting apparatus, then due to not with west to corresponding transmission jump number, can determine not forward described message.
