Patent Images
1. A method for determining location information, comprising:
- acquiring current location information of a communication network node in a network;
determining the acquired location information as current location information of a radio sensor node providing service data to the communication network node;
writing the determined current location information of the radio sensor node into data bits reserved for writing the location information in a service data packet constituted of the service data; and
providing a corresponding demander with the service data packet into which the current location information of the radio sensor node is written.
