Abstract
A mobile station (MS), a base station subsystem (BSS), and various methods are described herein that enable a positioning node (e.g., Serving Mobile Location Center (SMLC)) to improve the accuracy of estimating a position of the mobile station.
Claims8
A base station subsystem (BSS) configured to interact with a Serving Mobile Location Center (SMLC), the BSS comprising:
- a processor;
- and,
- a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the BSS is operable to:
- transmit, to the SMLC, a Base Station Subsystem Mobile Application Part-Location Services Extension (BSSMAP-LE) PERFORM LOCATION REQUEST message which includes an Information Element (IE) which indicates a worst case synchronization accuracy of a mobile station.
A method in a base station subsystem (BSS) configured to interact with a Serving Mobile Location Center (SMLC), the method comprising:
- transmitting (1202), to the SMLC, a Base Station Subsystem Mobile Application Part-Location Services Extension (BSSMAP-LE) PERFORM LOCATION REQUEST message which includes an Information Element (IE) which indicates a worst case synchronization accuracy of a mobile station.
A base station subsystem (BSS) configured to interact with a Serving Mobile Location Center (SMLC) and including a base transceiver station (BTS), the BSS comprising:
- a processor;
- and,
- a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the BSS is operable to:
- transmit, to the SMLC, a Base Station Subsystem Mobile Application Part-Location Services Extension (BSSMAP-LE) CONNECTION ORIENTED INFORMATION message which includes a BTS timing advance (TA) accuracy estimated by the BTS.
A method in a base station subsystem (BSS) which includes a base transceiver station (BTS) and is configured to interact with a Serving Mobile Location Center (SMLC), the method comprising:
- transmitting, to the SMLC, a Base Station Subsystem Mobile Application Part-Location Services Extension (BSSMAP-LE) CONNECTION ORIENTED INFORMATION message which includes a BTS timing advance (TA) accuracy estimated by the BTS.
