Embodiment Construction

[0053] For ease of understanding, an example of an explanation of concepts related to the embodiments of the present application is provided for reference, as follows:

[0054] The positioning server, a network element in the core network (CN), is mainly used to control the positioning measurement performed by the UE, such as configuring the neighboring cell measurement list of the UE and controlling the base station to issue positioning measurement signals through auxiliary data, or Control the UE to send positioning measurement signals through auxiliary data. In the embodiment of the present application, for example, the base station may be a Node B in a UMTS system, and the positioning server may be a network controller. For another example, the base station may be a small station, and the positioning server may be a macro base station covering the small station. For another example, the positioning server may be a wireless network cross-standard collaborative controller, etc...

Abstract

The invention discloses a method and device for sending a positioning signal, which are used for determining a target access network to send the positioning signal when a first device or a second device is kept in a connection state with two access networks. The method comprises the steps that the first device determines a first target access network for transmitting a positioning signal, whereinthe first target access network comprises at least one of a first access network and a second access network; and the first device sends the positioning signal to a second device by using the first target access network.

Description

Technical field [0001] This application relates to the field of wireless communication technologies, and in particular to a method and device for transmitting positioning signals. Background technique [0002] With the development of communication services, location services are playing an important role as an indispensable part of mobile communication and personal communication services. The positioning service is a value-added service that obtains the location information (such as latitude and longitude coordinates) of the mobile terminal user through the network of the telecommunications mobile operator. With the support of the electronic map platform, it can provide the user with a value-added service. Among them, the positioning algorithm based on time different of arrival (TDOA) is an important algorithm for realizing positioning services. The principle is: when there are three or more base stations in the system, the positioning server can use different base station downli...
