Abstract:
A wireless communication device sends positioning messages on the random access channels in two or more cells of a wireless communication network, where the messages exhibit one or more characteristics enabling the network to differentiate them as positioning messages rather than access messages ( 604 ). Correspondingly, the network uses the received messages as a basis for estimating timing advance values for the device with respect to the two or more cells ( 606 ), and it commonly links the cell-specific timing advance values to a device identifier included in the positioning messages by the device ( 608 ). The inclusion of the device identifier allows a positioning node to recognize the timing advance values as being associated with the same wireless communication device, for use in multilateration-based positioning estimation.

Claim (Index 39):
One or more network nodes configured for operation in a wireless communication network, the one or more network nodes comprising:\n communication circuitry configured to receive, for each of two or more cells of the wireless communication network, an access message sent by a wireless communication device on a random access channel used for random access in the cell, each of the two or more cells having corresponding cell identifier; and processing circuitry configured to, for each of the two or more cells:\n differentiate the received message as a positioning message rather than an access request message, based on determining that the received message exhibits one or more characteristics defined for positioning messages; \n estimate a timing advance value for the wireless communication device, based on the received message; and \n link the timing advance value to the corresponding cell identifier, and to a device identifier included in the received message, said device identifier uniquely identifying the wireless communication device to a positioning node; \n said processing circuitry being further configured to send the timing advance values and the linked cell and device identifiers towards the positioning node, for use by the positioning node in calculating a position of the wireless communication device from the timing advance values and linked cell identifiers.
