Title: NOTIFICATION OF DELIVERY OF A RRLP MULTILATERATION TIMNG ADVANCE REQUEST MESSAGE TO A BASE STATION SUBSYSTEM (BSS)
Abstract:
The present disclosure describes various techniques for enabling a Serving GPRS Support Node (SGSN) to provide a Base Station System (BSS) with an indication that a Logical Link Control (LLC) Protocol Data Unit (PDU) sent to a given wireless device contains a Radio Resource Location services Protocol (RRLP) Multilateration Timing Advance Request message such that the BSS after transmitting the LLC PDU to the given wireless device may invoke Timing Advance estimation algorithms for reception of uplink Packet Associated Control Channel (PACCH) acknowledgement block(s) (e.g., Extended Coverage (EC)-PACCH acknowledgment block(s)) from the given wireless device.
