Description

Method for positioning, small base station and macro base station

The present invention relates to the field of communications, and more particularly to a method for positioning, a small base station, and a macro base station in the field of communications. Background technique

Positioning technology is a technique used to determine the geographic location of a mobile station ("MS") or a terminal. The positioning technology can utilize the resources of the wireless communication network to obtain the location information of the mobile station directly or indirectly.

In the Long Term Evolution (LTE) system, the standard methods for terminal location are as follows: Network-assisted Global Navigation Satellite System (GNSS) Positioning, Observed Time Difference of Arrival (OTDOA) positioning, enhanced 'J, zone identifier (enhanced Cell ID), and uplink arrival time difference (Uplink) Time Difference of Arrival, called "UTDOA" positioning.

The LTE mobile station positioning method generally can detect the characteristic parameters of the radio wave propagation signal between the mobile station and the base station, such as the signal field strength, the propagation signal arrival time difference, the signal arrival direction angle, etc., and then estimate the mobile station according to the relevant positioning algorithm. Geometric location. The GNSS positioning method requires the terminal to have a wireless receiver that receives the GNSS signal, and specific implementations of the GNSS include, for example, GPS positioning. OTDOA positioning and e-CID positioning are both types of network positioning. They mainly rely on the detection of radio resource characteristic parameters inside the mobile communication system, and then estimate the location of the mobile station according to the positioning algorithm. The OTDOA positioning uses the mobile station to receive downlink positioning reference signals from multiple base stations to perform timing measurement, and reports a positioning reference signal (Positioning Reference Signal, called "PRS") arrival time difference between the base stations, so that the OTDOA positioning can be performed on the network positioning server. Calculate the geographic location of the mobile station. The UTDOA positioning performs timing measurement according to a plurality of positioning measurement units ("LMU") and/or an uplink signal sent by the mobile station received by the base station, and reports the arrival time of the uplink signal, so that the positioning can be performed. The geographical location of the mobile station is calculated on the server.

With the continuous development of mobile communication technologies, the demand for location services is increasing. The application scenario of the location service presents a diversified trend, such as emergency help positioning, criminal location chasing Trace, navigation and traffic control. However, regardless of the variety of application scenarios, the industry's need for positioning is always to obtain reliable, efficient and fast positioning methods; in other words, easy to implement and high-precision positioning technology has always been a hot spot.

In addition, in order to increase coverage and user experience, current research hopes to increase the coverage of small cells in the original wireless network to enhance coverage and user experience. For example, many nodes can be deployed in hotspots or high-rise buildings, resulting in many small cells. The newly added small cell and the normal cell may have the same frequency point, and may also have different frequency points.

When a small cell is introduced, a base station of a small cell (referred to as a "small base station") may pass through a base station of a macro cell (referred to as a "macro base station") and a mobility management entity (a Mobility Management Entity, which is called "MME"). )connection. In this application scenario, the small base station is not directly connected to the MME or the core network, but uses the macro base station as an intermediate node for connecting to the core network or the MME.

Therefore, in the application scenario including the small base station, the signaling in the current positioning method cannot support the complete positioning measurement interaction, and the target terminal cannot be located, and the user experience is poor. Summary of the invention
