Embodiment 1
[0119] Figure 8 for T ADV A schematic diagram of the type judgment implementation process, as shown in the figure, may include the following steps:
[0120] Step 801, the E-SMLC receives the location service request sent by the MME;
[0121] Step 802, perform corresponding positioning capability interaction according to the positioning capability obtained by the E-SMLC;
[0122] Step 803, E-SMLC selects the E-CID positioning method according to QoS (information such as positioning accuracy and time delay) in the positioning service request and the positioning capabilities of each node;
[0123]Step 804, the E-SMLC sends a location message request to the eNB through the LPPa protocol, which carries the QOS for this positioning;
[0124] Step 805, according to the QOS carried in the message, the eNB combines the UE wireless capability and its own positioning capability (including whether it supports T ADV Type1, T ADV Type2), select T ADV Specific types, perform correspo...

[0126] 1) After receiving the positioning service request sent by the MME, the E-SMLC performs corresponding positioning capability interaction according to the positioning capability obtained by the E-SMLC;
[0127] 2), E-SMLC selects the E-CID positioning method according to the QoS (such as positioning accuracy and delay information) in the positioning service request and the positioning capabilities of each node;
[0128] 3), E-SMLC sends a location message request to eNB through LPPa protocol;
[0129] 4), eNB combines UE wireless capabilities and its own positioning capabilities (including whether it supports T ADV Type1, T ADV Type2), determine whether T is supported in this positioning process ADV TYPE1, T ADV TYPE2 measurement. If T ADV TYPE1, T ADV TYPE2 measurement is supported, T is preferred ADV Type1. eNB chooses T ADV After specifying the type, perform the corresponding measurement and reporting process.

Abstract
The invention discloses a positioning processing method and positioning processing equipment. The method comprises the following steps that: user equipment (UE) determines supporting capacity of measuring and reporting transceiving time difference of UE; and UE reports UE wireless capacity information, wherein the UE wireless capacity information carries the information of supporting capacity of measuring and reporting transceiving time difference of UE. Through the method and the equipment, the problems of how to notify whether network UE supports to measure and report the transceiving time difference of UE and how to select time advance (TADV) measurement types in the conventional enhanced cell identification (E-CID) positioning scheme are solved; therefore, an evolved node B (eNB) can determine the supported TADV measurement type in the positioning process by combining the positioning capacity of the eNB.
Description
technical field [0001] The present invention relates to positioning technology, in particular to a positioning processing method and equipment. Background technique [0002] Mobile positioning service means that the mobile network obtains the geographic location information (latitude and longitude coordinates) of the mobile terminal through a specific positioning technology, provides it to the mobile user himself, the communication system or a third party, and provides mobile users with the support of certain electronic map information. Calling or non-calling traffic related to its location. [0003] figure 1 It is a schematic diagram of the positioning architecture of E-UTRAN (Evolution-Universal Terrestrial Radio Access Network, evolved global terrestrial radio access network). The positioning architecture related to E-UTRAN is shown in the figure. This architecture supports control plane positioning and user plane positioning . During the positioning process of the con...
