Embodiment
Below in conjunction with the accompanying drawing in embodiments of the invention, the technical scheme in embodiments of the invention is clearly and completely described, obviously, the embodiments described below are only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of embodiments of the invention protection.
Embodiment one
The embodiment of the present invention one provides a kind of method of locating Home eNodeB, as shown in Figure 1a, comprising:
Step 101, location-server receives the Location Request of Home eNodeB;
Step 102, described location-server sends location information request to described Home eNodeB;
Step 103, described location-server are determined the position of described Home eNodeB according to the positional information of the described Home eNodeB that receives;
Step 104, described location-server send the results messages of the position of carrying described Home eNodeB to described Home eNodeB.
Wherein, the Location Request of described location-server reception Home eNodeB comprises: described Home eNodeB sends the first Location Request by the S1 message of configuration to MME; Described MME processes described the first Location Request, sends second Location Request by the SLs message that configures to described location-server according to result, carries the identification information of the described Home eNodeB in location in described the second Location Request.
Described location-server is after described Home eNodeB sends the results messages of the position of carrying described Home eNodeB, also comprise: described Home eNodeB sends to described MME and discharges localization message, makes the described MME deletion contextual information relevant to the location of described Home eNodeB.
Described location-server comprises to the results messages that described Home eNodeB sends the position of carrying described Home eNodeB: described location-server sends the location response message of the position of carrying described Home eNodeB to described MME; Described MME sends the position of described Home eNodeB to described Home eNodeB, and the release contextual information relevant to the location of described Home eNodeB.
Before described location-server sent location information request to described Home eNodeB, also comprise: described location-server sent the stationkeeping ability query messages to described Home eNodeB; Described location-server is selected corresponding localization method according to the stationkeeping ability reporting message of described Home eNodeB, sends the auxiliary data information corresponding with described localization method to described Home eNodeB.
Described location information request, results messages, stationkeeping ability query messages and auxiliary data information all send by LPPa message.
The below introduces the method with said method in the example that is applied as in the LTE system.
As shown in Fig. 1 b, in the LTE system, connect by X2 interface between eNB, connect by the S1 interface between eNB and MME, HeNB can directly connect with MME, also can be linked into MME by a centralized node HeNB GW, there is no interface between HeNB, HeNB can only be connected with a HeNB GW simultaneously.
Embodiment two
The embodiment of the present invention two provides a kind of method of locating Home eNodeB, and as shown in Figure 2, the method comprises the following steps:
Step 201, the Home eNodeB start sends locating request message by S1 message to MME.
Need explanation, if the sign that can carry Home eNodeB in this Location Request is by HGW, the sign that also can carry HGW.This S1 message is the pre-configured S1 message that is used for sending Location Request.
Step 202, MME receives that Home eNodeB passes through the Location Request that S1 message sends, and sends the SLs interface message according to this S1 message to E-SMLC, request E-SMLC positions Home eNodeB.
Information in MME storage S1 message for Home eNodeB related relevant E-SMLC and Route Distinguisher, identifies in the SLs interface message and need to position for this Home eNodeB, and this SLs interface message is locating request message.
Step 203 after E-SMLC receives the SLs interface message of MME transmission, sends the LPPa message of inquiry stationkeeping ability to Home eNodeB according to the identification information in this message.
Need explanation, the stationkeeping ability of E-SMLC and nonessential inquiry Home eNodeB, for example, E-SMLC can determine according to the mode of making an appointment the stationkeeping ability of Home eNodeB.
Step 204, Home eNodeB are received the LPPa message of the inquiry stationkeeping ability that E-SMLC sends, and its stationkeeping ability that can support is reported E-SMLC.
In order to make LPPa message can be used in the stationkeeping ability of inquiry Home eNodeB, in the embodiment of the present invention, LPPa message is expanded.Need explanation, this expansion is can realize that above-mentioned functions is as the criterion, and the embodiment of the present invention does not limit the concrete form of LPPa message.
The below is to describe as example according to the localization message format configuration LPPa message of LPP agreement.
To require auxiliary data as example, Figure 3 shows that in the LPP agreement to define about the message body that auxiliary data is provided, in the embodiment of the present invention, the auxiliary data of definition LPPa agreement (for example: NB LCS ASSISTANCE DATA INFO) as shown in table 1 gives information.
Table 1
Can be so that E-SMLC provides auxiliary data to HENB by this message.
Step 205 after E-SMLC receives the stationkeeping ability that the base station reports, is selected suitable localization method according to its ability information, and is provided auxiliary data information by LPPa message.
This auxiliary data information determines according to actual needs, and for example E-SMLC selects to adopt OTDOA(Observed Time Difference Of Arrival, observes arriving the time difference) localization method, the cell list of OTDOA is sent to Home eNodeB.
Step 206, E-SMLC sends location information request to Home eNodeB, and the indication Home eNodeB reports location dependent information (being mainly requirement reporting measurement result).
Step 207, Home eNodeB reports E-SMLC with measurement result by LPPa message (positional information provides or the measurement result reporting message) according to location information request.
For example, Home eNodeB is measured the cell signal RSTD(reception signal time deviation in the OTDOA cell list).Home eNodeB is organized information reporting according to the reporting information in location information request message, and measurement result is sent to E-SMLC.
Step 208, E-SMLC receives the measurement result that Home eNodeB reports, and calculates the position of Home eNodeB according to these measurement results.
Step 209, Home eNodeB receive E-SMLC by the measurement result that LPPa message sends, and determine the position of self according to this measurement result.
Step 210, Home eNodeB send to MME and discharge localization message, MME deletion located in connection context, and position fixing process finishes.
Concrete, discharge and can carry HENB sign or Route Distinguisher in localization message, be used to indicate MME and discharge relevant location context.
Embodiment three
The embodiment of the present invention three provides a kind of method of locating Home eNodeB, and as shown in Figure 4, the method comprises the following steps:
Step 401 ~ 408 are identical with above-mentioned steps 201 ~ 208.
Step 409, E-SMLC sends location response message to MME by SLs message.
Step 410, MME sends positional information to Home eNodeB, and discharges relevant location contextual information, finishes position fixing process.
Obtained the positional information of self at Home eNodeB after, Home eNodeB can report this positional information OM or other network entities as required.
Based on the same or analogous technical conceive of said method embodiment, the present invention also provides following apparatus embodiment.
