Abstract: The present disclosure discloses a method and an apparatus for managing quality of service in a wireless communications system. A radio access network device receives service data through n bearers between a core network device and the radio access network device, where the service data includes a plurality of service flows mapped to the n bearers, and n is an integer greater than or equal to 1. The radio access network device performs flow demapping of the received service data according to a QoS rule, to obtain the plurality of service flows. The radio access network device maps, according to the QoS rule, at least some of the plurality of service flows obtained through the flow demapping to t bearers between the radio access network device and a user equipment for transmission, where t is an integer greater than or equal to 1.

Abstract: The present invention provides a positioning parameter coordination apparatus, system, and method. A single positioning controller (SPC) receives a positioning request message sent by a positioning request device, obtains capability information of a user equipment (UE) according to an identifier of the UE, and determines at least one first access network device to complete positioning configuration. The SPC positions the UE according to a positioning parameter of the UE.

Abstract: Embodiments of the present disclosure provide a positioning method based on a time difference of arrival, user equipment, and a network device. The method includes: calculating, by user equipment, a first time difference of arrival RSTD1 based on positioning signals sent by a first base station and a second base station at a same moment; calculating a second time difference of arrival RSTD2 based on known location information of the user equipment; calculating a time alignment error TAE based on the RSTD1 and the RSTD2; and performing, based on the TAE, positioning based on a time difference of arrival TDOA. According to this method, the TAE caused by the base stations is subtracted during positioning calculation. In other words, the time alignment error caused by the base stations is eliminated. Therefore, accuracy of TDOA-based positioning can be ensured.
