detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

At present, there are four types of LCS (Location services): Commercial LCS (value-added service), the Internal LCS (internal positioning), the Emergency LCS (emergency call) and the Lawful Intercept LCS (legal interception) ). For the SON network (Self Optimized Network), the LCS of the Internal LCS type is mainly required. In the embodiment of the present invention, the LCS of the Internal LCS type will also be described as an example.

In the embodiment of the present invention, several network architectures are provided, as shown in Figures 16, 17, 18, and 19, respectively. In the architecture shown in FIG. 16, the OAM (Operation and Maintenance Management) entity and the eNB directly perform signaling interaction, and the eNB and the MME (Mobility Management Entity) perform signaling interaction through the S1 interface. Between the MME and the E-SMLC (Evolved Serving Mobile Location Centre), the signaling interaction is performed through the SLs interface. The E6 and the HSS communicate with each other through the S6a interface. The E- and VGMLC pass the SLg. The interface performs signaling interaction, signaling between the UE and the eNB, and data/voice interaction; the architecture shown in FIG. 17 and the architecture described in FIG. 16 are not The 0AM and the E-SMLC directly perform signaling interaction. The architecture shown in FIG. 18 is different from the architecture shown in FIG. 16 and FIG. In the architecture shown in FIG. 19, signaling interaction between the eNB and the MME through the S1-MME interface, signaling between the UE and the eNB, and data/voice interaction.

In order to implement the positioning of the user equipment in the LTE system, the first embodiment of the present invention provides a positioning method of the user equipment. In the method for locating the user equipment according to the first embodiment of the present invention, after the location request message is sent by the entity to the evolved service mobile location center E-SMLC, the measurement request message is sent to the user equipment UE, and the Measurement report sent by the UE.

In the embodiment of the present invention, the entity that sends the location request message is an eNB or an 0AM entity. And the location information of the user equipment may be included in the measurement report, where the location information may include the final location information or the auxiliary location information of the user equipment, where the location information is included in the UE-based mode or the UE-as sisted mode. The auxiliary positioning information may include measurement results, measurement accuracy, and the like. When the measurement information includes the auxiliary positioning information, the network side entity, for example, the E-SMLC, calculates the positioning information of the user equipment according to the auxiliary positioning information.

In addition, in order to enable network optimization, the network side entity obtains the wireless side measurement MR (Measurement Report) data and the flag in addition to the location information of the user equipment. The MR data may include, for example, RSRP (Reference Reference Received Power) or RSRQ (Reference S ignal Received Qualification). Here, the network side entity may be an eNB, an E-SMLC, or an 0AM. Then, the network side entity may associate the final location information of the user equipment with the wireless side measurement report according to the label, thereby performing network optimization, such as reducing a road test scenario, and automatically optimizing the scene by using an RF (Radio Frequency) parameter.

The tag may be one of a timestamp, a measurement identifier, an association identifier, a frame number, and a multiframe number. The timestamp is obtained when the UE performs the measurement, such as the UE absolute time (or relative time) or other unique identifier that can identify the current measurement time of the UE; and the measurement identifier can be measured by the eNB in the measurement control sent to the UE. Carry in the message. The association identifier is assigned by the UE of. For the multiframe number, for some positioning methods that take a long time, such as AGPS, the general 5-l Os can be completed. In order to ensure that the wireless side measurement report and location information can be correctly associated, a frame number is assigned every 10ms, looping from 1 - 4096*n. The UE maintains the same multiframe number as the eNB. In addition, the UE may also use the frame number in the existing protocol as a flag.

The implementation of user equipment positioning in an LTE system is described in detail below in connection with different embodiments.

A second embodiment of the present invention provides a method for locating a user equipment. The embodiment is implemented based on the architecture shown in FIG. 16. As shown in FIG. 1, the method in the second embodiment of the present invention includes the following steps: Step 11. The eNB sends a positioning request message (Location Reques t) to the E-SMLC through the MME. The positioning request message may carry one or any combination of information such as an eNB ID (eNB identifier), a cel l ID (cell identifier), a TAC (Tracking Area Code), a UE identifier, and the like.

Step 12: The E-SMLC performs legality verification on the eNB.

In addition, the E-SMLC can also perform legality verification on the user equipment. The process of authenticating an eNB or user equipment may include two aspects:

1. The eNB is authenticated when an interface is established between the eNB and the MME and between the eNB and the E-SMLC to determine that the eNB has the right to locate the user equipment. If the eNB requires a positioning process for a certain user equipment or some user equipments, the E-SMLC may also initiate a validity check on a certain user equipment or some user equipments, that is, the step is performed before step 11.

2. When the eNB sends a location request message, the E-SMLC performs legality verification on the eNB or the user equipment. The process of verifying the UE is mainly performed by the E-SMLC to identify the UE that is reported by the eNB (for example, the UE ID assigned by the UE to the UE, or the identifier allocated by the eNB to the UE), and the eNB needs to pass the LPP2 (LTE Positioning Protoco). l, the LTE positioning protocol 2) the interface sends the identifier to the E-SMLC) and associates with the IMSI (Internationa Mobi le Subscr iber Identation, International Mobile Subscriber Identity) of the user equipment acquired by the E-SMLC itself. Come on. This process can be done by the E-SMLC in cooperation with the MME or other network entities such as HSS (Home Subscr iber Server, Home Subscriber Server). The verification of the eNB is mainly verified according to the eNB identifier reported by the eNB to determine the eNB. Has the ability to locate user devices.

Step 1 3: The E-SMLC sends a location response message (Loca ION ACK) to the eNB via the MME, where the location response message includes "pass" and "fail". If the location response message is passed, step 14 is performed; otherwise the positioning process ends.

Step 14: The eNB performs measurement configuration on the UE, and sends a measurement request message to the user equipment. For example, the eNB may construct the measurement content according to the RRM (Radio Resource Management) algorithm or the network rule network optimization policy, and send a measurement request message to the user equipment. The measurement request message includes positioning measurement information and wireless side measurement report control information requesting to obtain the data. The positioning measurement information may include positioning measurement assistance information, such as a neighbor relationship list, PCI, encrypted information, and the like.

Alternatively, the positioning measurement information or the radio side measurement report control information may be separately sent by the eNB to the UE by another message.

Step 15: The user equipment performs measurement according to the measurement request message.

Step 16. The user equipment sends a measurement report to the eNB.

Wherein, according to the measurement configuration performed by the eNB on the UE in step 14, in the UE-ba sed mode, the measurement report may include location information and a radio side measurement report; or the measurement report may include location information, a tag, and a wireless The side measurement report, at this time, the content in the measurement report can be separately reported, that is, the combination of the location information and the tag, the wireless side measurement report, and the tag are separately reported, and the two combined tags may be the same or different. In the UE-as sis ted mode, the measurement may include auxiliary positioning information such as measurement results, measurement accuracy, etc., marking, and wireless side measurement report. At this time, the content in the measurement report may be separately reported. .

Step 18: After calculating the location information of the user equipment according to the measurement report, the E-SMLC obtains an update measurement report, where the update measurement report includes the location information, the identifier, and the wireless Side measurement report. If the eNB needs the update measurement report, the E-SMLC may send the update measurement report to the eNB through the location response message (Loca ti on Response).

In the UE-based mode, steps 17 and 18 above are optional.

Step 19: If the operation and maintenance management entity 0AM triggers the positioning process, the eNB further needs to send the measurement report or the update measurement report to the operation and maintenance management entity 0AM.

Step 20: Associate the location information with the wireless side measurement report according to the measurement report or update the label in the measurement report to perform network optimization.

(3) The eNB sends the measurement report to the 0AM, and the 0AM associates the location information with the radio side measurement report according to the flag in the measurement report.

In the UE-ba sed mode, when the UE measurement report received by the eNB includes the location information and the wireless side measurement report, the process of association is not necessary. That is, it can be understood that, according to the measurement configuration in step 14, the measurement report reported by the user equipment is the already associated location information and the wireless side measurement report.

In UE-as s i s ted mode, there are several ways to associate:

(1) associating the location information with the wireless side measurement report by the E-SMLC center according to a flag in the updated measurement report;
