1. A method performed in a server node for assisting a first wireless communication device and a second wireless communication device to seek each other in a wireless communication network, comprising:
repeatedly inquiring positioning and movement information of the first and second wireless communication devices;
obtaining information on a relative position between the first and the second wireless communication devices; and
sending instructions to at least one of the first and second wireless communication devices based on the information on the relative position;
wherein a frequency of the repeatedly inquiring positioning and movement information of the first and second wireless communication devices is dependent on whether the second wireless communication device is at a junction of paths commonly taken by the second wireless communication device.
