Embodiment 1

[0036] Such as image 3 As shown, it is a signaling interaction diagram of user equipment positioning assistance data configuration in Embodiment 1 of the present invention, specifically including:

[0037] 301. Before the location request is initiated, the E-SMLC sends a location assistant information request to the MME through an SLs port message, such as sending a location assistant info request message;

[0038] 302. The above-mentioned MME forwards the received positioning assistance information request to the eNB through an S1 port message;

[0039] 303. In response to receiving the location assistance information request, the eNB sends a location assistance information response to the MME through an S1 message, for example, sends a location assistant info response message.

[0040] 304. The above-mentioned MME forwards the above-mentioned positioning assistance information response to the above-mentioned E-SMLC through an SLs port message.

[0041] The above positioning...

Embodiment 2

[0045] Since the positioning assistance information on the eNB side will change during network optimization or other scenarios, once the positioning assistance information changes, it is necessary to notify the E-SMLC in time, and the E-SMLC will update the relevant positioning assistance information, so as to ensure that the E-SMLC sends it to the The positioning assistance data of the UE is correct. Such as Figure 4 As shown, it is a signaling interaction diagram of UE positioning assistance data configuration in Embodiment 2 of the present invention, specifically including:

[0046] 401, the positioning assistance information on the eNB side changes, and the eNB sends an update indication to the MME through an S1 interface message, for example, an update indication message, the update indication carrying the updated information type (such as cell synchronization attributes, PCI, neighbor cell relationship list , LMU measurement, etc.);

[0047] 402. The above-mentioned M...

Embodiment 3

[0056] This embodiment mainly describes the signaling process for the eNB to actively send positioning assistance information to the E-SMLC. The contents of the positioning assistance information in this embodiment are the same as those in Embodiment 1 and Embodiment 2, and will not be repeated here. When the interface between eNB and MME, between MME and E-SMLC is established, such as Figure 5 As shown, it is a signaling interaction diagram of UE positioning assistance data configuration in Embodiment 3 of the present invention, specifically including:

[0057] 501. The eNB sends an S1 interface setup request message to the MME, for example, an S1 setup request message, and the message carries positioning assistance information.

[0058] 502. The above-mentioned MME sends an SLs interface establishment request message to the E-SMLC, for example, sends an SLs setuprequest message, and the message carries positioning assistance information.

[0059] 503. The above-mentioned E...

Abstract

The invention provides a positioning assisting data configuration method and a positioning assisting data configuration device for user equipment. The method comprises the following steps that: an evolved serving mobile location center (E-SMLC) acquires positioning assisting information from an evolved node B (eNB) through an S1 interface message and an SLs interface message; and the E-SMLC transmits the positioning assisting information serving as one of positioning assisting data to the user equipment (UE) for positioning. The embodiment of the invention discloses a positioning assisting data configuration flow in a long time evolution (LTE) system so as to supplement the conventional positioning framework flow.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for configuring user equipment positioning assistance data. Background technique [0002] At present, WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) optional positioning methods include OTDOA (Observed Time Difference Of Arrival, observed time difference of arrival), AGPS (Assisted Global Positioning Systems, assisted global positioning system), AOA ( Signal angle of arrival) + TA (time advance), UTDOA (uplink time difference of arrival), etc., LTE (long time evolution, long-term system evolution) system will continue to use these positioning methods. [0003] Both the AGPS and OTDOA methods in the above methods have two positioning modes: UE-based (UE-based) mode and UE-assisted (UE-assisted) mode. The difference between the above two positioning modes lies in: which network element performs position c...
