Method for determining location information of user terminal UE and network side equipment

Abstract

The present invention relates to the field of communications. In order to solve the problem that the determination of UE location information depends on the establishment of an RRC connection, a method for determining UE location information and configuring parameters for the UE is provided, including: determining the path loss threshold PLTH for the UE to enter the cell edge; determining The grouping threshold matched with the PLTH is sent to each UE in the cell, which is used as a path loss comparison reference when the UE initiates a competitive random access. The UE determines to select a preamble in a different group when initiating a competitive random access according to the comparison result ; During the random access process initiated by the UE, obtain the random access method selected by the UE; when the selected random access method is contention random access, obtain the preamble selected during random access; according to the selected The group to which the preamble belongs determines the location information of the UE. The invention can reduce the overhead of air interface signaling caused by blindly configuring parameters when the RRC is not established, and further improves the utilization rate of system resources.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for determining location information of a user terminal UE and network side equipment. Background technique [0002] From the perspective of user service requirements, people have higher and higher demands for location-related services (such as positioning, mobile phone maps, etc.) in mobile networks. From the perspective of overall system performance optimization, the network side needs to know the location information of users. Therefore, in subsequent evolution systems of the third generation mobile communication technology, such as the LTE (Long Term Evolution, Long Term Evolution) system and the LTE-A system, relevant provisions have been made on the method for determining the location information of the user terminal UE. [0003] Specifically, in the LTE system, in order to realize the same-frequency networking as much as possible, the LTE standard i...

Problems solved by technology

Due to the blindness of the above-mentioned assumption of the initial location information of the UE, it is inevitable that the system will need to reconfigure the above parameters with a high probability, which will inevitably bring unnecessary overhead of air interface resources, thereby reducing the capacity of the system

At the same time, before the network side obtains the correct location information of the UE, if it is assumed to provide services for the UE according to the wrong location information, it will inevitably make it difficult to satisfy the QoS of the UE, thereby affecting user experience.
