Problems solved by technology

However, due to reasons such as multi-path propagation (mutli-path propagation) or client capabilities, there will be different delays in the arrival time of positioning signals at the client, resulting in inaccurate measurement results
Therefore, the client's location estimated by the network will be inaccurate, thus affecting the positioning performance
[0011] In the third case, the client may perform different measurements, such as a mobile measurement, a positioning measurement, and a signal quality measurement, etc.
However, the LTE-A system does not clearly define the transmission order of the measurement reports related to the above measurement procedures, that is, the priority of transmitting the positioning measurement reports
In this case, the transmission of the positioning measurement report may be delayed, causing a delay in positioning

Embodiment Construction

[0038] Please refer to figure 1 , figure 1It is a schematic diagram of a wireless communication system 10 according to an embodiment of the present invention. The wireless communication system 10 is preferably an advanced long-term evolution system (Long Term Evolution Advanced, LTE-Advanced), which is briefly composed of a network terminal and a plurality of mobile devices, and operates in a coordinated multi-point transmission / Receive (Coordinated Multipoint Transmission / Reception, COMP) function. In the LTE-Advanced system, the network side can be an evolved universal terrestrial radio access network (evolved-UTRAN, EUTRAN), which can include multiple evolved base stations (eNBs) or a core network side (for example: mobility management Unit (mobility management entity, MME)), and mobile devices can be regarded as clients (UEs), such as mobile phones, computer systems and other devices. In addition, according to the transmission direction, the network and the client can ...

Abstract

A method of enhancing positioning measurement for a mobile device in a wireless communications system is disclosed. The method comprises initiating a positioning measurement automatically or when a service of the mobile device is triggered or initiated.

Description

technical field [0001] The present invention relates to a method used in a wireless communication system and its communication device, in particular to a method used in a wireless communication system to improve the positioning measurement function and its communication device. Background technique [0002] The Long Term Evolution (LTE) wireless communication system formulated by the 3rd Generation Partnership Project (3GPP) is currently considered to provide high data transmission rate, low latency, packet optimization and A new wireless interface and wireless network architecture to improve system capacity and coverage. In the LTE wireless communication system, the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN) includes multiple enhanced base stations (evolved Node-B, eNB) used to communicate with multiple UEs (User Equipment, UE) for communication. A UE in an LTE system can utilize a single component carr...
