All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without departing from the inventive scope are the scope of the embodiments of the present invention.

Embodiment 1

A method for locating a home base station is provided in the first embodiment of the present invention. As shown in FIG.

Step 101: The positioning server receives a positioning request of the home base station.

Step 102: The location server sends a location information request to the home base station. Step 103: The location server determines, according to the received location information of the home base station, a location of the home base station.

Step 104: The positioning server sends a result message carrying the location of the home base station to the home base station.

The receiving, by the positioning server, the location request of the home base station includes: the home base station sending a first location request to the MME (Mobility Management Entity, the mobility management entity) by using the configured S1 message; The processing is performed, and the second positioning request is sent to the positioning server by using the configured SLs message according to the processing result, where the second positioning request carries the identification information of the home base station.

After the location server sends the result message of the location of the home base station to the home base station, the method further includes: the home base station sending a release location message to the MME, so that the MME deletes the location of the home base station Relevant context information.

The sending, by the positioning server, the result message of the location of the home base station to the home base station, includes: the positioning server sending a positioning response message carrying the location of the home base station to the MME; The location of the base station to the The home base station transmits and releases context information related to the location of the home base station. Before the location server sends the location information request to the home base station, the method further includes: the location server sending a location capability query message to the home base station; the location server selecting a corresponding message according to the location capability report message of the home base station The positioning method sends auxiliary data information corresponding to the positioning method to the home base station.

The location information request, the result message, the location capability query message, and the auxiliary data information are all sent through the LPPa message.

The method is described below by taking the application of the above method in an LTE system as an example.

As shown in FIG. 1B, in the LTE system, the eNBs are connected through the X2 interface, and the eNB and the MME are connected through the S1 interface. The HeNB can be directly connected to the MME, or can be accessed to the MME through a centralized node HeNB GW. There is no interface between them,

The HeNB can only be connected to one HeNB GW at the same time.

Embodiment 2

A second embodiment of the present invention provides a method for locating a home base station. As shown in FIG. 2, the method includes the following steps:

Step 201: The home base station is powered on, and sends a location request message to the MME by using an S1 message.

It should be noted that the location request may carry the identifier of the home base station, and may also carry the identifier of the HGW if it passes through the HGW (Home Gateway). The S1 message is a pre-configured S1 message for sending a positioning request.

Step 202: The MME receives the location request sent by the home base station by using the S1 message, and sends an SLs interface message to the E-SMLC (Evolved Serving Mobile Location Centre) according to the S1 message, requesting the E-SMLC to perform the home base station. Positioning.

The MME stores the information in the S1 message, and associates the related E-SMLC and the route identifier with the home base station, and identifies the location to be addressed to the home base station in the SLs interface message, where the SLs interface message is a location request message.

Step 203: After receiving the SLs interface message sent by the MME, the E-SMLC sends an LPPa message for querying the positioning capability to the home base station according to the identifier information in the message. It should be noted that the E-SMLC does not have to query the positioning capability of the home base station. For example, the E-SMLC can determine the positioning capability of the home base station according to a predetermined manner.

Step 204: The home base station receives the LPPa message of the query location capability sent by the E-SMLC, and reports the locating capability that can be supported by the E-SMLC to the E-SMLC.

In order to enable the LPPa message to be used to query the location capability of the home base station, the LPPa message is extended in the embodiment of the present invention. It should be noted that the extension is based on the foregoing functions, and the embodiment of the present invention does not limit the specific format of the LPPa message.

The following describes an example of configuring an LPPa message according to the positioning message format of the LPP protocol.

For example, the NB LCS ASSISTANCE DATA INFO is defined in the LPP protocol, and the auxiliary data providing message (for example, NB LCS ASSISTANCE DATA INFO ) is defined in the LPP protocol. Shown.

Table 1

IE/Group Name (IE/group name Presence IE type and reference) (parameter (IE type and reference) is necessary

Must appear)

Message Type M 9.2.3

LPPa Transaction ID ( LPPa M 9.2.4

Common 0 content can be the same as LPP IEsProvideAssistanceData (for the definition in the secondary

Common data provided by the aid data)

A-GNSS-ProvideAssistanceD 0 content can be the same as defined in LPP ata (providing A-GNSS related auxiliary data)

OTDOA-ProvideAssistanceD 0 content can be the same as defined in LPP ata (providing OTDOA related auxiliary data) This message allows the E-SMLC to provide assistance data to the HENB.

Step 205: After receiving the positioning capability reported by the base station, the E-SMLC selects an appropriate positioning method according to the capability information, and provides the auxiliary data information by using the LPPa message.

The auxiliary data information is determined according to actual needs. For example, the E-SMLC selects an OTDOA (observed Time Difference Of Arrival) positioning method to transmit the OTDOA cell list to the home base station.

Step 206: The E-SMLC sends a location information request to the home base station, and instructs the home base station to report location related information (mainly, requesting to report the measurement result).

In step 207, the home base station reports the measurement result to the E-SMLC through the LPPa message (location information providing or measurement result reporting message) according to the location information request.

For example, the home base station measures the cell signal RSTD (received signal time offset) in the OTDOA cell list. The home base station reports the report according to the report information in the location information request message, and sends the measurement result to the E-SMLC.

Step 208: The E-SMLC receives the measurement result reported by the home base station, and calculates the location of the home base station according to the measurement results.

Step 209: The home base station receives the measurement result sent by the E-SMLC through the LPPa message, and determines its location according to the measurement result.

Step 210: The home base station sends a release location message to the MME, and the MME deletes the relevant location context, and the positioning process ends.

Specifically, the release location message may carry the HENB identifier or the route identifier, and is used to instruct the MME to release the related positioning context. Embodiment 3

Steps 401 to 408 are the same as steps 201 to 208 described above.

Step 409: The E-SMLC sends a location response message to the MME by using an SLs message. Step 410: The MME sends the location information to the home base station, and releases the related positioning context information, and ends the positioning process. After the home base station obtains its own location information, the home base station can report the location information to the OM or other network entity as needed. The present invention also provides the following device embodiments based on the same or similar technical concept as the above method embodiments.
