Title: NETWORK NODES AND METHODS THEREIN FOR MULTILATERATION
Abstract:
Embodiments herein relate to a method performed by a first access network node 411, for positioning of a wireless communication device 430. The method comprises obtaining a first and a second information relating to multilateration of the wireless communication device 430. The first information relating to multilateration comprises a first timing advance value, or a first indication of the first timing advance value, associated with the first access network node 411 and the wireless communication device 430, a Temporary Logical Link Identifier (TLLI) corresponding to the wireless communication device 430 and a first identity of a first cell 421, in which first cell 421 the first timing advance was obtained. The method further comprises mapping, based on the TLLI, the associated first and second identities of the first and second cells 421, 422 and the first and second timing advance values to a network layer protocol connection on a first interface 441. The method further comprises transmitting, to a positioning node 413, the first and second timing advance values and the first and second identities of the first and second cells 421, 422. Embodiments herein further relate to corresponding methods in a second access network node 412 and in a positioning node 413.
