Abstract

Embodiments of the present invention disclose a method, a device and a system for implementing directional broadcast in mobile data broadcasting. In the method, upon receiving a broadcast message from a content server, a network element processes the broadcast message according to first location information carried in the broadcast message and second location information in the network element. In the embodiments of the present invention, with the first location information carried in the broadcast message and the second location information set in the network element, upon receiving the broadcast message, the network element processes the broadcast message according to the first location information and the second location information, so that the content server may implement directional broadcast for a special location area without directly accessing a directional location area, which reduces the network complexity.

if the first location information matches the location information of the network element, sending the broadcast message;

otherwise, discarding the broadcast message.

3. The method of claim 2, wherein the network element sends the broadcast message through broadcasting.

4. The method of claim 2, wherein the network element sends the broadcast message to a subordinate network element or to a next network element.

5. The method of claim 1, wherein the process of processing the broadcast message according to the first location information and the second location information comprises:

determining whether the first location information matches the second location information;

if the first location information matches the second location information, showing or playing the broadcast message;

otherwise, discarding the broadcast message.

6. The method of claim 1, wherein the second location information comprises the location information of the network element and location information of other network elements related to the network element;

and

the process of processing the broadcast message according to the first location information and the second location information comprises;

determining, by the network element, whether the first location information matches the location information of the network element;

if the first location information matches the location information of the network element, sending the broadcast message according to matched location information;

otherwise, finding one or more network elements, the location of the one or more network elements being proximal to the location indicated in the first location information according to the location information of said other network elements related to the network element, and sending the broadcast message to the one or more network elements.

7. The method of claim 6, further comprising:

before determining whether the first location information matches the location information of the network element, determining, by the network element, whether the location indicated in the first location information is contrary to the location indicated in the location information of the network element;

if the location indicated in the first location information is contrary to the location indicated in the location information of the network element, discarding the broadcast message.

8. The method of claim 6, further comprising:

before finding the one or more network elements, determining, by the network element, whether the location indicated in the first location information is contrary to the location indicated in the location information of the network element;

if the location indicated in the first location information is contrary to the location indicated in the location information of the network element, discarding the broadcast message.

9. The method of claim 6, wherein the process of sending the broadcast message according to the matched location information comprises:

determining, by the network element, whether the first location information completely matches the location information of the network element;

if the first location information completely matches the location information of the network element, sending the broadcast message to all subordinate network elements or all next network elements among said other network elements related to the network element;

otherwise, determining, by the network element, whether the first location information partially matches the location information of the network element;

if the first location information partially matches the location information of the network element, sending the broadcast message to a subordinate network element or a next network element among said other network elements related to the network element according to both a matched part and the location information of said other network elements related to the network element.

10. The method of claim 9, wherein the process of sending the broadcast message to the subordinate network element or the next network element according to both the matched part and the location information of said other network elements related to the network element comprises:

searching the location information of said other network elements related to the network element to find the location information matching the matched part, and sending the broadcast message to the subordinate network element or the next network element corresponding to the location information matching the matched part.

11. The method of claim 9, further comprising:

upon sending the broadcast message to the subordinate network element or the next network element according to both the matched part and the location information of said other network elements related to the network element,

searching the location information of said other network elements related to the network element to find location information of one or more network elements;

wherein the location indicated in the location information of one or more network elements is proximal to the location indicated in an unmatched part, and sending the broadcast message to the one or more network elements corresponding to the location information found.

12. The method of claim 1, wherein the location information comprises latitude and longitude information or geographical name information.

13. A network element comprising:
