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.
Claims24
A mobile station configured to interact with a base station subsystem (BSS), the BSS including a base transceiver station (BTS), the mobile station 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 mobile station is operable to:
- receive, from the BSS, a multilateration request;
- in response to receipt of the multilateration request, estimate a synchronization accuracy with the BTS, and estimate a transmission offset for uplink transmissions to the BTS;
- and,
- transmit, to the BSS, a Radio Link Control (RLC) data block that includes at least (i) a Temporary Logical Link Identifier (TLLI) of the mobile station, (ii) the estimated synchronization accuracy, and (iii) the estimated transmission offset.
A method in a mobile station configured to interact with a base station subsystem (BSS), the BSS including a base transceiver station (BTS), the method comprising:
- receiving, from the BSS, a multilateration request;
- in response to receiving the multilateration request, estimating a synchronization accuracy with the BTS, and estimating a transmission offset for uplink transmissions to the BTS;
- and,
- transmitting, to the BSS, a Radio Link Control (RLC) data block that includes at least (i) a Temporary Logical Link Identifier (TLLI) of the mobile station, (ii) the estimated synchronization accuracy, and (iii) the estimated transmission offset.
A base station subsystem (B SS) configured to interact with a mobile station and a Serving Mobile Location Center (SMLC), wherein the BSS includes 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 mobile station, a multilateration request;
- and,
- receive, from the mobile station, a Radio Link Control (RLC) data block that includes at least (i) a Temporary Logical Link Identifier (TLLI) of the mobile station, (ii) an estimated mobile station synchronization accuracy, and (iii) a mobile station transmission offset.
A method in a base station subsystem (BSS) configured to interact with a mobile station and a Serving Mobile Location Center (SMLC), wherein the BSS includes a base transceiver station (BTS), the method comprising:
