Problems solved by technology

[0007] The disadvantage of the above solution is that: when the positioning response time in the positioning request issued by the core network is required to be fast, and at the same time, the horizontal positioning accuracy is not high, then the RNC can completely use the CELLID method to perform positioning processing at this time. In order to be able to meet the positioning response time requirements in the positioning request while satisfying the horizontal positioning accuracy
In this solution, the RNC must wait until the AGPS positioning measurement with the longest measurement time has the result before performing positioning calculations. When the horizontal positioning accuracy of the core network is not high, the positioning time is wasted.
Another disadvantage of this solution is: the positioning measurement of CELLID and OTDOA is successful, but if the UE returns the AGPS positioning measurement failure after a period of time, then the positioning result reported by the RNC to the core network at this time is not suitable for motion conditions. If the UE is down, it cannot reflect the current actual location of the UE. What the RNC reports is only the previous positioning results of the UE.

Embodiment Construction

[0037] The core idea of ​​the present invention is to provide a mobile station positioning processing method. The RNC first selects the initial positioning method according to the positioning request information of the core network, the positioning capability of the UE, and the type of cell accessed by the UE. If the positioning fails , the RNC uses the positioning method downgrade processing, and selects the downgraded positioning method for mobile station positioning processing according to the UE's positioning capability, the type of cell accessed by the UE, etc., ensuring that the RNC can obtain the most suitable location for the core network every time. The requested positioning result can also ensure that the positioning time is as short as possible.

[0038] The present invention provides a positioning processing method for a mobile station. The operation flow of an embodiment of the method is shown in FIG. 1 , including the following steps:

Abstract

The method comprises: according to the location request information of core network, location capability of subscriber equipment and information about cell type, the radio network control (RNC) selects an initial location method to make location process; if satisfying the location requirement, then ending the location process; if location process failures, according to the location capability of user and the type of accessed cell, making a location degradation process; after the location method is selected, using the selected location method to locate the mobile station.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a positioning processing method of a mobile station. Background technique [0002] In the WCDMA (Wideband Code Division Multiple Access) mobile communication system, there are three standard positioning methods: AGPS (Network Assisted GPS Positioning Method), OTDOA (Observation Time Difference) and CELLID (Cell Identification). The positioning accuracy of each positioning method is different. Generally speaking, the positioning accuracy of AGPS is the highest, followed by OTDOA, and the positioning accuracy of CELLID is the worst. [0003] However, for different geographical environments, such as: outdoor open environment, outdoor occluded environment, indoor, etc., the positioning accuracy of each positioning method varies greatly. For example: in an open outdoor environment, the positioning accuracy of the AGPS method can reach within 10 meters, the positioning accuracy ...
