Embodiment Construction

[0036] In the embodiment of the present invention, in order to enable the HeNB in ​​the LTE system to have positioning-related functions, the positioning process for the HeNB is redesigned. Since the HeNB cannot interact with other HeNBs or eNBs through the air interface (that is, the wireless interface, the S1 interface and the X2 interface belong to the wired interface), therefore, in the embodiment of the present invention, the HeNB needs to exchange information with the E-SMLC, using the S1 interface The LPP message (LTE positioning protocol message) used in the positioning process is carried by the protocol, that is, the HeNB is regarded as a terminal to perform positioning, and the positioning protocol used by the terminal is adopted. Specifically:

[0037] The HeNB sends the location request message to the location server E-SMLC based on the S1 interface, and performs location measurement according to the instructions of the E-SMLC, and sends the location measurement re...

Abstract

The invention discloses a method and a device for positioning a home node B (HeNB), which relates to the field of communication and is used for accurately mastering the position information of the HeNB. The method comprises the following steps that: the HeNB sends a positioning request message to an evolved serving mobile location center (E-SMLC) based on an S1 interface, the E-SMLC instructs theHeNB to perform positioning measurement, and the HeNB is positioned according to a positioning measurement result returned by the HeNB so as to acquire the position information of the HeNB; and the HeNB receives a positioning response message from the E-SMLC based on the S1 interface, and determines the physical position of the HeNB according to the position information carried in the positioningresponse message. Therefore, based on an S1 interface protocol and a lightweight presentation protocol (LPP), the interactive process between the HeNB and the E-SMLC is redefined so as to accurately position the HeNB, perform effective management on the premise of promptly mastering the specific distribution condition of the HeNB, and ensure system performance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for positioning HeNB. Background technique [0002] With the development of communication technology, the network architecture of the LTE (Long Term Evolution, long-term evolution) system is becoming more and more perfect. refer to figure 1 As shown in the R9 protocol, it is stipulated in the E-UTRAN (Evolved Universal Terrestrial Radio Access Network) in the LTE system that in addition to the eNB (base station), HeNB (Home Node B, home base station) is also allowed to be set. The X2 interface is used between eNBs, and the S1 interface is used between eNB and MME (MME (Mobility Management Entity, mobile management entity). The HeNB can be directly connected to the MME through the S1 interface, or can be connected to a relay node HeNBGW ( Home base station gateway), and then access to the MME through the HeNB GW, there is no interface between the HeNBs, and ...
