Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 3, fig. 3 is a flowchart of an information processing method provided in an embodiment of the present invention, and is applied to a network element device, as shown in fig. 3, the method includes the following steps:

301, obtaining position measurement information of each LMU in a plurality of LMUs, wherein the LMUs are connected with the same BBU.

In this embodiment, the network element device may be a device configured to uniformly report the location measurement information of the plurality of LMUs, for example, the network element device may uniformly report the location measurement information of the plurality of LMUs to a location service device, such as an E-SMLC, so that the location service device locates a location of a user equipment UE based on the location measurement information uniformly reported by the network element device. For convenience of understanding, in the embodiments of the present invention, the description is given by taking E-SMLC as a reporting object.

Specifically, as shown in fig. 4, a plurality of Pico-RRUs are connected to one BBU, and one LMU is integrally deployed in each Pico-RRU, so that each LMU can measure the location information of the UE by receiving a signal sent by the UE.

In this step, the obtaining of the location measurement information of each LMU of the plurality of LMUs may be collecting the location information measured by each LMU of the plurality of LMUs, for example, receiving the location measurement information reported by each LMU. In this way, by acquiring the location measurement information of each LMU in the plurality of LMUs, the location measurement information of each LMU can be reported uniformly without reporting each LMU individually, and the data transmission pressure of the location service equipment receiving the location measurement information of each LMU can be reduced.

And step 302, uniformly reporting the position measurement information of each LMU.

After the location measurement information of each LMU in the plurality of LMUs is obtained, the location measurement information of each LMU may be uniformly reported, specifically, the location measurement information of each LMU may be uniformly reported to a device that needs to use the location measurement information, for example, the E-SMLC, and the E-SMLC may perform location calculation based on the location measurement information of each LMU.

The network element device may establish a communication connection with the E-SMLC, for example, the network element device may have a separate communication interface with the E-SMLC, and the two may transmit data through mutually supported communication protocols.

Therefore, compared with the prior art, the method for realizing the positioning of the UE has the advantages that the structure is simple and the implementation is easy, only the communication interface is needed to be established between the network element equipment and the E-SMLC, and the data transmission pressure of the E-SMLC is relatively small due to the adoption of the mode of uniformly reporting the position measurement information of a plurality of LMUs.

In the information processing method in this embodiment, by obtaining the location measurement information of each LMU of the plurality of LMUs, where the plurality of LMUs are connected to the same BBU, and reporting the location measurement information of each LMU in a unified manner, it is possible to avoid that each LMU reports the location measurement information separately, so that data transmission pressure on the location service equipment that receives the location measurement information of each LMU can be reduced, and the implementation manner is relatively simple.

Referring to fig. 5, fig. 5 is a flowchart of another information processing method provided in the embodiment of the present invention, which is applied to a network element device, and this embodiment defines a specific implementation manner how to uniformly report location measurement information of each LMU on the basis of the embodiment shown in fig. 3, so that how to uniformly report location measurement information of each LMU is more clear and specific. As shown in fig. 5, the method comprises the steps of:

step 501, obtaining position measurement information of each LMU in a plurality of LMUs, wherein the LMUs are connected with the same BBU.

The specific implementation of this step may refer to the implementation of step 301 in the method embodiment shown in fig. 3, and is not described here again to avoid repetition.

Optionally, the network element device is a master location measurement unit S-LMU in the plurality of LMUs, or an LMU integrally deployed in the BBU.

In this embodiment, the network element device may be an S-LMU of the plurality of LMUs, that is, a certain LMU of the plurality of LMUs may be preset as the S-LMU, and used as a master node for uniformly reporting the location measurement information; or the network element device may also be an LMU integrally deployed in the BBU, and collect, through the LMU, location measurement information of each LMU in the plurality of LMUs, and report the location measurement information in a unified manner.

For example: as shown in fig. 4, a plurality of Pico-RRUs are connected to the same BBU, and each Pico-RRU is integrally deployed with one LMU, so that the LMU integrally deployed on one Pico-RRU can be set as an S-LMU, and a separate communication interface (such as an SLm interface) is established between the S-LMU and the E-SMLC, so that the LMUs integrally deployed on other Pico-RRUs collectively collect the measurement location information of the UE to the S-LMU, and the measurement location information is reported to the E-SMLC by the S-LMU through the SLm interface; or, an LMU may be integrally deployed on the BBU, and the LMU may collect measurement location information of the LMU integrally deployed on all Pico-RRUs to the UE, and report the measurement location information to the E-SMLC through the SLm interface in a unified manner.

Thus, in this embodiment, one LMU is set as an S-LMU in the plurality of LMUs, or LMUs are integrally deployed in the BBU to obtain location measurement information of each LMU in the plurality of LMUs, and the location measurement information of each LMU is uniformly reported, so that the LMUs can be used to complete uniform reporting of information, which is not only easy to implement, but also low in investment cost.

Of course, this embodiment can be applied to the embodiment shown in fig. 3 as well, and the same advantageous effects can be achieved.

And 502, uniformly reporting the position measurement information of each LMU through the measurement response message.

In this embodiment, when performing unified reporting on the location measurement information of each LMU, the unified reporting may be specifically completed through a measurement response message, where the measurement response message may be a response message that is sent by the E-SMLC, and that is sent to the E-SMLC and includes location measurement information of each LMU, and the location measurement information of each LMU is obtained after the network element device receives a measurement request message sent by the E-SMLC.

For example: as shown in fig. 6, the communication flow between the S-LMU and the E-SMLC is: E-SMLC sends a Measurement Request message SLmAP Measurement Request to S-LMU through an SLm interface; and after receiving the Measurement request message, the S-LMU sends a Measurement Response message (SLmAP Measurement Response) to the E-SMLC, wherein the Measurement Response message carries the position Measurement information of each LMU in the plurality of LMUs, which is acquired by the S-LMU.

Optionally, the measurement response message may include a measurement result indication field, where the measurement result indication field carries the location measurement information of each LMU.

In this embodiment, the measurement response message may include a measurement result indication field, so that the location measurement information of each LMU may be added to the measurement result indication field to complete the unified reporting of the location measurement information of each LMU through the measurement response message, and after receiving the measurement response message, the E-SLMC may extract the location measurement information of each LMU from the measurement result indication field.

For example: as shown in table 1 below, the Measurement Response Message SLmAP Measurement Response may include a Message Type, a Transaction identifier SLmAP Transaction ID, a Measurement identifier E-SMLC Measurement ID, an uplink received signal time Measurement value UL RTOA measurements, and critical diagnostic criteria, where the UL RTOA measurements are the Measurement result indication field, and the UL RTOA measurements may carry the location Measurement information of each LMU.

In this way, in this embodiment, by adding the measurement result indication field to the measurement response message and carrying the location measurement information of each LMU in the measurement result indication field, the location measurement information of each LMU can be uniformly reported relatively easily and conveniently, and it can be ensured that the E-SMLC can relatively easily extract the location measurement information of each LMU from the measurement result indication field of the measurement response message.

TABLE 1 SLmAP Measurement Response

Optionally, the location measurement information of each LMU may be sorted according to the identifier of the corresponding LMU in the measurement result indication field.

In this embodiment, when the location measurement information of each LMU is carried in the measurement result indication field in the measurement response message, the location measurement information of each LMU may be sorted in the measurement result indication field according to the identifier of the corresponding LMU, so that it may be ensured that, after the E-SMLC receives the measurement response message, the measurement result information corresponding to each LMU in the plurality of LMUs may be quickly and accurately obtained through the identifier of the LMU indicated in the measurement result indication field.

In a specific implementation, the content of the measurement result indication field may be modified in different ways to add the location measurement information of each LMU to the measurement result indication field, for example: as shown in table 2 below, the UL RTOA measurements field of a single LMU may include the content UL RTOA measurements, as well as the sub-content uplink evolved terrestrial radio access network absolute radio channel number UL EARFCN and the uplink received signal time UL RTOA.

In a first mode, as shown in table 3 below, a sub-content LMU identifier LMU ID and an LMU measurement value UL RTOA LMU Measurements are added to the UL RTOA Measurements, and a Range value of the UL RTOA Measurements is modified according to the number of the LMUs, where the content LMU ID and the UL RTOA LMU Measurements respectively represent the LMU identifier and the location measurement information corresponding to the LMU, maxnotuslaultoa represents the maximum number of LMUs connected to the same BBU, maxnotuloa represents the maximum measurement value, and maxnotulrtoa represents the maximum supported frequency band.

In this way, the location measurement information of each LMU may be cascaded in the sub-content LMU ID and UL RTOA LMU measures according to the identifier of the corresponding LMU, and in this way, by introducing maxNoLMUULRTOA to indicate the number of LMUs connected to the BBU, the UL RTOA measures need to include maxNoLMUULRTOA UL RTOA LMU measures.

TABLE 2 UL RTOA measures

TABLE 3 UL RTOA measurements

In the second mode, as shown in table 4 below, the name of the measurement result indication field UL RTOA Measurements is modified into a measurement result List UL RTOA Measurements List, and an LMU identifier LMU ID and corresponding measurement values UL RTOA Measurements are sequentially added to the measurement result List. In this way, the location measurement information of each LMU may be sequentially added to the LMU ID and the UL RTOA Measurements according to the identifier of the corresponding LMU, and in this way, the Range value of the UL RTOA Measurements List is infinitely determined, and it is only necessary to sequentially List the location measurement information of the LMUs in the UL RTOA Measurements List.

TABLE 4 UL RTOA measures

Thus, in this embodiment, the location measurement information of each LMU is sorted in the measurement result indication field according to the identifier of the corresponding LMU, so that the location measurement information of each LMU is conveniently added, and the E-SMLC can be ensured to quickly and accurately obtain the measurement result information corresponding to each LMU in the plurality of LMUs through the identifier of the LMU indicated in the measurement result indication field.

Optionally, the measurement response message may include a plurality of sub-response messages, the plurality of sub-response messages correspond to the plurality of LMUs one to one, and each sub-response message carries an identifier of a corresponding LMU and location measurement information.

In this embodiment, the measurement response message may include a plurality of sub-response messages, and each of the plurality of sub-response messages may correspond to each of the plurality of LMUs, that is, each sub-response message carries an identifier and location measurement information corresponding to one LMU. In this way, a sub-response message can be generated according to the identifier and the position measurement information of each LMU in the plurality of LMUs, and finally the plurality of sub-response messages are combined into the measurement response message for packaging and reporting.

For example, a complete Measurement response message, the slmapmeasurement response, can be as follows:

LMU ID 1

Message Type

SLmAP Transaction ID

E-SMLC Measurement ID

UL RTOA measurements (location measurement information corresponding to LMU ID 1)

Criticality Diagnostics

LMU ID 2

Message Type

SLmAP Transaction ID

E-SMLC Measurement ID

UL RTOA measures (location measurement information corresponding to LMU ID 2)

Criticality Diagnostics

……

The LMU ID 1, the LMU ID 2 and the like respectively represent the identification of the LMU corresponding to the sub-response message, and the UL RTOA measures in each sub-response message respectively represent the position measurement information of the LMU corresponding to the sub-response message.

In this way, the identifier and the position measurement information of each LMU in the plurality of LMUs are respectively carried into one sub-response message, and the measurement response message combined by the plurality of sub-response messages is reported, so that the unified reporting of the position measurement information of each LMU can be realized.

Optionally, the measurement response message may include a quantity indication field, where the quantity indication field carries indication information indicating the quantity of the reported location measurement information of the LMU.

In this embodiment, the measurement response message may further include a quantity indication field, where the quantity indication field carries indication information indicating the quantity of the reported location measurement information of the LMUs, and specifically, a quantity indication field may be newly defined to indicate the quantity information of the reported location measurement information of the LMUs, that is, to indicate the quantity of the location measurement information included in the measurement response message, corresponding to the quantity of the LMUs having reported location measurement information, and the quantity indication field is added to the measurement response message. For example, the number indication field may be as shown in table 5 below, and values of maxnoaulrtoa, maxeearfcn, and maxnoalmuulrtoa in the measurement response message are explained as follows.

TABLE 5 Range bound

In this way, in this embodiment, the number indication field is newly added in the measurement response message to indicate the number of the location measurement information of the LMUs reported in the measurement response message, so that the E-SMLC can intuitively know the number of the location measurement information of the LMUs reported or the number of the LMUs having the location measurement information reported.

In this embodiment, the location measurement information of each LMU is reported in a unified manner through the measurement response message, so that the manner of reporting the location measurement information is relatively simple, and the location measurement information in the LMUs can be reported in a unified manner through a plurality of implementation manners, so that the manner of reporting the location information of the LMUs is relatively flexible.

In addition, the embodiment also adds a plurality of optional implementation manners on the basis of the embodiment shown in fig. 3, and these optional implementation manners may be implemented in combination with each other or separately, and both can achieve the technical effects of reducing the data transmission pressure on the location service equipment that receives the location measurement information of each LMU, and being simple in implementation manner.
