发明名称 METHOD AND ARRANGEMENT FOR REAL-TIME DIFFERENCE DETERMINATION FOR MOBILE TERMINAL POSITIONING
摘要 In a method of providing real time difference determination for a mobile terminal in a telecommunication system, comprising a plurality of eNodeBs in communication with a core network, each eNodeB having a plurality of associated cells, each cell potentially servicing one or more mobile terminals, determining S10 a first timing advance value representative of a first geographical distance measure between the mobile terminal and a first serving eNodeB prior to a handover to a second serving eNode B, determining S20 a second timing advance value representative of a second geographical distance measure between the mobile terminal and the second eNodeB after the handover. Subsequently, determining S30 a time of arrival measure between the mobile terminal and at least two eNodeBs, and signaling S40 representations of the determined first and second geographical distance measures and the determined time of arrival measures for said mobile terminal to at least said second eNodeB, together with a respective unique identification parameter of the at least two eNodeBs, wherein determination of real time differences is enabled based on at least the signaled representations.
