1. A method for determining mobility of a node in a wireless communication network, the method comprising within the node:
- receiving mobility status information from a plurality of other nodes operating within the wireless communication network, wherein the mobility status information identifies each of the other nodes as either a mobile node or a stationary node;
measuring distance information representing a change in distance between the node and each of the stationary nodes in the wireless communication network; and
identifying the node as mobile when the node determines from the measured distance information that it is mobile before each of the other stationary nodes is identified as mobile.

Abstract
A system and method for determining the mobility of a node (102) in a wireless communication network (102). The system and method determine the distance between the node (102) and at least one stationary neighboring node (102, 106, 107) at at least two or more time points, using at least two moving average filters, to arrive at two distance values. The system and method then determine the relative velocity based on the at least two distance values, and thus determine whether the node (102) is mobile.

8. A method for determining mobility of a node in a wireless communication network, the method comprising:
-
operating the node to receive respective information from each of a plurality of other nodes in the network, each respective information indicating whether the respective other node is identified as a mobile node or a stationary node; operating the node to determine its respective relative velocity with respect to each of a plurality of other nodes in the network; and operating the node to determine whether it should be identified as mobile or stationary based on the respective relative velocities and the respective information. - View Dependent Claims (9, 10, 11)

12. A node, for communication in a wireless network, comprising:
-
a transceiver; and a controller, operating to control the transceiver to communicate with at least one other node in the wireless communication network including receiving mobility status information from a plurality of other nodes operating within the wireless communication network, wherein the mobility status information identifies each of the other nodes as either a mobile node or a stationary node, and further operating to measure distance information representing a change in distance between the node and the each of the stationary nodes in the wireless communication network, and to identify the node as mobile when the node determines from the measured distance information that it is mobile before each of the other stationary nodes is identified as mobile. - View Dependent Claims (13, 14, 15, 16, 17, 18)
