Description

Broadcast method of positioning auxiliary information, positioning server and RAN node

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for broadcasting positioning assistance information, a positioning server, and a RAN node.

Background

Currently, in a New Radio interface (NR), when broadcasting of Positioning assistance Information is implemented, a general procedure may be that a Positioning Management entity (LMF) sends Positioning assistance Information to be broadcasted to a base station, the base station stores the received Positioning assistance Information and broadcasts it via System Information (SI), and then a Radio Resource Control (RRC) layer of a terminal receives the broadcast of the Positioning assistance Information and submits it to an LTE Positioning Protocol (LPP) for processing.

In addition, in the SI of NR, the transmission manner thereof may be divided into two types including a periodic broadcast and a broadcast based on terminal request assignment (on-demand). The periodic broadcast mode is that in an SI time window corresponding to an SI message calculated according to a formula, a network side always sends the SI message; the broadcasting mode based on the terminal request is that if no terminal request exists, the network side does not send the SI message, and if the terminal sends the request to the network side, the network side sends the SI message within a period of time in an SI time window corresponding to the SI message calculated according to a formula.

Although the broadcast of the positioning assistance information can be divided into the above two manners, there is no solution at present how to decide whether to broadcast periodically or to broadcast based on terminal request allocation.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.

As shown in fig. 1, which is a flowchart illustrating steps of a method for broadcasting positioning assistance information according to an embodiment of the present invention, the method includes the following steps:

step 101: and sending a broadcast indication message to a Radio Access Network (RAN) node, wherein the broadcast indication message carries broadcast mode indication information of the positioning auxiliary information.

Specifically, the positioning server may send a broadcast indication message to a Radio Access Network (RAN) node, where the broadcast indication message carries broadcast mode indication information of the positioning assistance information, so that the RAN node can determine which mode is used to broadcast the positioning assistance information according to the broadcast mode indication information.

Wherein the broadcast mode indication information includes at least one of the following information:

first, indication information of whether the positioning assistance information needs to be periodically broadcasted.

In this case, the positioning server indicates whether the positioning assistance information needs to be broadcast all the time in the broadcast indication message;

second, the indication information of the broadcast priority of the positioning assistance information.

Specifically, the broadcast priority may be indicated by a high priority or a low priority, or a numerical value in a preset range may be defined, and the priority is determined according to the high or low of the numerical value.

And thirdly, indication information for periodically broadcasting the positioning auxiliary information.

In this case, the positioning server explicitly instructs the broadcast mode of the positioning assistance information in the broadcast instruction message, that is, instructs the periodic broadcast of the positioning assistance information.

And fourthly, indicating information for broadcasting the positioning auxiliary information based on the terminal request.

In this case, the positioning server explicitly instructs the broadcast method of the positioning assistance information in the broadcast instruction message, that is, instructs the method of requesting allocation based on the terminal, and broadcasts the positioning assistance information.

In the following, specific examples of the indication information indicating whether the positioning assistance information needs to be periodically broadcasted and the indication information indicating the broadcasting priority of the positioning assistance information in the broadcasting manner indication information are given.

For example, the positioning server may determine whether the positioning assistance information to be broadcasted needs to be broadcasted all the time or determine the broadcasting priority of the positioning assistance information to be broadcasted based on the principle specified by the positioning server. For example, if a certain positioning assistance information is paid by the provider, the positioning server may set the positioning assistance information to be broadcasted periodically, that is, to be broadcasted all the time, or set the priority of the broadcast to be a high priority (which may also be a high priority value); or based on the industry requirement, if the delay requirement of a certain positioning assistance information is high, the positioning server may set the positioning assistance information to be required to be periodically broadcast, or set the positioning assistance information to be at a high priority. For another example, if the positioning server knows that the terminal has a high demand for certain positioning assistance information according to the positioning assistance information request of the terminal, the positioning server may set the positioning assistance information to be required to be periodically broadcasted or set the positioning assistance information to be of a high priority; further to general positioning assistance information, the positioning server may set the positioning assistance information to require periodic broadcast, or to a general or low priority of its broadcast priority.

In this way, by carrying at least one of the above information in the broadcast mode indication information, when the positioning server sends the broadcast indication message to the RAN node, the RAN node can determine, according to the broadcast mode indication information, which mode to use to broadcast the positioning assistance information.

Further, when the broadcast indication message is sent to the RAN node in the radio access network, the following method may be included:

sending the broadcast indication message to the RAN node aiming at a System Information Block (SIB) corresponding to each positioning auxiliary information; alternatively, the first and second liquid crystal display panels may be,

sending the broadcast indication message to the RAN node aiming at a system message SI corresponding to each positioning auxiliary information; alternatively, the first and second electrodes may be,

and sending the broadcast indication message to the RAN node aiming at all the positioning auxiliary information which needs to be broadcasted currently.

Specifically, the positioning server may set broadcast mode indication Information for each piece of positioning assistance Information to be broadcast, that is, each positioning System Information Block (System Information Block), and send a broadcast indication message carrying the broadcast mode indication Information to the RAN node; the method can also set broadcast mode indication information aiming at the SI corresponding to each positioning auxiliary information needing to be broadcast, and send broadcast indication information carrying the broadcast mode indication information to the RAN node; the broadcast mode indication information can be set aiming at all the positioning auxiliary information which needs to be broadcasted currently, and the broadcast indication information carrying the broadcast mode indication information is sent to the RAN node, so that the diversity of the positioning server in configuring the broadcast indication information is realized.

Furthermore, after sending the broadcast instruction message to the RAN node, the positioning server may also receive a feedback message sent by the RAN node, where the feedback message carries broadcast result information of the positioning assistance information.

Specifically, when receiving the feedback message sent by the RAN node, the RAN node may receive a feedback message of the positioning assistance information in each cell; or receiving a feedback message of the positioning assistance information under the RAN node.

Further, specifically, the broadcast result information includes at least one of the following information:

identification information of positioning assistance information that is periodically broadcasted;

identification information of positioning assistance information that cannot be periodically broadcast;

identification information of positioning assistance information broadcasted based on a terminal request;

indication information whether broadcasting can be performed according to the broadcasting mode indication information;

identification information of positioning auxiliary information which can not be broadcasted according to the broadcast mode indication information;

identification information of positioning auxiliary information which can be broadcasted according to the broadcasting mode indication information;

indication information which can not be broadcasted according to the broadcasting priority in the broadcasting mode indication information;

identification information of positioning auxiliary information which can not be broadcasted according to the broadcasting priority in the broadcasting mode indication information;

identification information of positioning auxiliary information which can be broadcasted according to the broadcasting priority in the broadcasting mode indication information;

the identification information is an identifier of an SIB corresponding to each positioning assistance information, or an identifier of an SI corresponding to each positioning assistance information.

Specifically, since the positioning server may send the broadcast indication message based on the SIB corresponding to the positioning assistance information or based on the SI corresponding to the positioning assistance information, when the RAN node feeds back the broadcast result information, the identification information of the positioning assistance information may be an identification of the SIB corresponding to each positioning assistance information or an identification of the SI corresponding to each positioning assistance information, so as to correspond to a sending manner of the positioning assistance information.

Thus, by using at least one of the above information as the broadcast result information, when the positioning server receives the feedback message sent by the RAN node, it can determine which positioning assistance information is periodically broadcast, which positioning assistance information cannot be periodically broadcast, which positioning assistance information is broadcast based on the terminal request, whether it can be broadcast according to the broadcast mode indication information, which positioning assistance information cannot be broadcast according to the broadcast mode indication information, which positioning assistance information can be broadcast according to the broadcast mode indication information, whether it can be broadcast according to the broadcast priority in the broadcast mode indication information, which positioning assistance information cannot be broadcast according to the broadcast priority, which positioning assistance information can be broadcast according to the broadcast priority, and the like, so that the positioning server can determine, according to the feedback message, it is determined that subsequent operations, such as if periodic broadcast positioning assistance information is required and the RAN node feedback fails to provide relevant services, the positioning server may provide the required positioning assistance information in other manners, such as in a user plane positioning manner, in time.

In this way, in this embodiment, by sending the broadcast indication message to the RAN node, and the broadcast indication message carries the broadcast mode indication information of the positioning assistance information, the RAN node can determine which mode to use to broadcast the positioning assistance information based on the broadcast mode indication information in the broadcast indication message, thereby solving the problem that in the prior art, which mode to use to broadcast the positioning assistance information cannot be determined.

In addition, as shown in fig. 2, a second step flow chart of the broadcasting method of positioning assistance information in the embodiment of the present invention is shown, and the broadcasting method specifically includes the following steps:

step 201: and receiving a broadcast indication message sent by the positioning server.

In this step, specifically, the RAN node receives a broadcast indication message sent by the location server. The broadcast indication message carries broadcast mode indication information of the positioning auxiliary information.

Specifically, the broadcast mode indication information includes at least one of the following information: indication information of whether the positioning assistance information needs to be periodically broadcasted; indication information of a broadcast priority of the positioning assistance information; indication information for periodically broadcasting the positioning assistance information; and indicating information for broadcasting the positioning auxiliary information based on a terminal request.

It should be noted that the content of the broadcast mode indication information is the same as the content of the broadcast mode indication information at the positioning server side, and the specific content of the broadcast mode indication information in this embodiment may refer to the specific description of the broadcast mode indication information at the positioning server side, which is not described herein again.

In addition, specifically, when receiving the broadcast indication message sent by the positioning server, the RAN node may include the following manners:

receiving a broadcast indication message sent by the positioning server aiming at a System Information Block (SIB) corresponding to each positioning auxiliary information; or receiving a broadcast indication message sent by the positioning server for a system message SI corresponding to each positioning auxiliary information; or receiving a broadcast indication message sent by the positioning server for all positioning assistance information which needs to be broadcasted currently.

Specifically, the RAN node can correspondingly receive the broadcast indication message sent by the positioning server, thereby realizing diversity of the broadcast indication message received by the RAN node.

Step 202: and determining the broadcasting mode of the positioning auxiliary information according to the broadcasting mode indication information.

In this step, specifically, after receiving the broadcast indication message, the RAN node may determine the broadcast mode of the positioning assistance information according to the broadcast mode indication information.

Specifically, when the broadcast mode of the positioning assistance information is determined according to the broadcast mode indication information, the broadcast mode of the positioning assistance information may be determined to be a periodic broadcast or a broadcast based on a terminal request according to the broadcast mode indication information.

For example, for the positioning assistance information set to be required to be broadcasted periodically, the positioning assistance information may be broadcasted in a periodic broadcast manner, that is, in a constantly-broadcasted manner, and the positioning assistance information that is not set to be required to be broadcasted periodically is broadcasted in a manner based on a terminal request; or in the case of resource shortage, the positioning auxiliary information set to be required to be periodically broadcasted can be refused to be broadcasted; or in the case of a relatively short resource, broadcasting the positioning assistance information in a periodic broadcast manner for the positioning assistance information with a higher broadcast priority, and broadcasting the positioning assistance information in a terminal request-based manner for the positioning assistance information with a lower priority, or in the case of a relatively short resource, broadcasting the positioning assistance information in a periodic broadcast manner for the positioning assistance information with a higher priority, and broadcasting the positioning assistance information in a terminal request-based manner for the positioning assistance information with a lower priority, or even refusing to broadcast a certain positioning assistance information, etc.

In this way, the RAN node determines whether the broadcast mode of the positioning assistance information is periodic broadcast or broadcast based on a terminal request according to the broadcast indication message and by combining the self condition, thereby realizing the determination of the broadcast mode of the positioning assistance information.

Furthermore, after determining the broadcast mode of the positioning assistance information according to the broadcast mode indication information, the RAN node may also send a feedback message to the positioning server, where the feedback message carries broadcast result information of the positioning assistance information.

Specifically, when sending the feedback message to the positioning server, the feedback message of the positioning assistance information in each cell may be sent to the positioning server; or sending a feedback message of the positioning assistance information under the RAN node to the positioning server.

In addition, specifically, the broadcast result information includes at least one of the following information:

identification information of positioning auxiliary information which can not be broadcasted according to the broadcasting mode indication information;

It should be noted that the content of the broadcast result information is the same as the content of the broadcast result information of the positioning server side, and the specific content of the broadcast result information in this embodiment may refer to the specific description of the broadcast result information by the positioning server side, which is not described herein again.

The following describes the interaction procedure between the location server side and the RAN node.

Specifically, the positioning server configures the broadcast mode indication information of the positioning assistance information in advance, for example, may determine whether the positioning assistance information to be broadcast needs to be periodically broadcast or determine the broadcast priority of the positioning assistance information to be broadcast based on a rule specified by the positioning server. Then, the positioning server sends a broadcast indication message to the RAN node, where the broadcast indication message carries broadcast mode indication information of the positioning assistance information, and at this time, the RAN node determines, according to the broadcast mode indication information in the received broadcast indication message, a broadcast mode of the positioning assistance information, that is, which positioning assistance information can be periodically broadcast, and which positioning assistance information is broadcast in a mode based on a terminal request. Optionally, after determining the broadcast mode of the positioning assistance information, the RAN node sends a feedback message to the positioning server to feed back broadcast result information, such as identification information of the positioning assistance information that is periodically broadcast, identification information of the positioning assistance information that cannot be periodically broadcast, identification information of the positioning assistance information that is broadcast based on a terminal request, and indication information of whether the positioning assistance information can be broadcast according to the broadcast mode indication information, where the positioning server determines a subsequent operation process of the positioning assistance information according to the feedback message.

In this way, in this embodiment, the RAN side determines the broadcast mode of the positioning assistance information by receiving the broadcast indication message sent by the positioning server, where the broadcast indication message carries the broadcast mode indication information of the positioning assistance information, and then determining the broadcast mode of the positioning assistance information according to the broadcast mode indication information.

In addition, in the NR system, in particular, the RAN node may be further separated into a Central Unit (CU) and a Distributed Unit (DU), where the underlying configuration and scheduling may be generated by the DU and the RRC message is generated by the CU.

In this CU-DUC scenario, as shown in fig. 3, which is a third flowchart illustrating steps of a method for broadcasting positioning assistance information according to an embodiment of the present invention, the method for broadcasting positioning assistance information may include the following steps:

step 301: and receiving a broadcast indication message sent by the positioning server.

In this step, specifically, when the positioning server sends the broadcast indication message to the RAN node, the CU in the RAN node may receive the broadcast indication message.

It should be noted that the content of the broadcast mode indication information is the same as the content of the broadcast mode indication information of the positioning server side, and the specific content of the broadcast mode indication information in this embodiment may refer to the specific description of the broadcast mode indication information of the positioning server side, which is not described herein again.

In addition, specifically, when receiving the broadcast indication message sent by the positioning server, the CU may include the following manners:

Step 302: the broadcast indication message is sent to the distribution unit DU.

In this step, specifically, after receiving the broadcast indication message, the CU may send the broadcast indication message to the DU, so that the DU can determine the broadcast mode of the positioning assistance information according to the broadcast indication message and by combining its own condition.

Further, after sending the broadcast indication message to the DU, the CU may also receive a feedback message sent by the DU, where the feedback message carries broadcast result information of the positioning assistance information.

Specifically, after receiving the feedback message sent by the DU, the CU may also send the feedback message to the positioning server, so that the positioning server can perform subsequent operations according to the feedback message.

identification information of positioning auxiliary information broadcasted based on a terminal request;

identification information of positioning auxiliary information which can be broadcasted according to the broadcast mode indication information;

In this way, the CU sends the received broadcast instruction message to the DU, so that the DU can determine the broadcast mode of the positioning assistance information according to the broadcast instruction message, thereby achieving the determination of the broadcast mode of the positioning assistance information in the CU-DU scene.

In addition, as shown in fig. 4, a fourth step flowchart of the method for broadcasting positioning assistance information according to the embodiment of the present invention includes the following steps:

step 401: receiving a broadcast indication message sent by the central unit CU.

In this step, specifically, the DU receives the broadcast instruction message transmitted by the CU.

Specifically, the broadcast mode indication information includes at least one of the following information: indication information of whether the positioning assistance information needs to be periodically broadcasted; indication information of a broadcast priority of the positioning assistance information; indication information for periodically broadcasting the positioning assistance information; and indication information for broadcasting the positioning assistance information based on a terminal request.

Step 402: and determining the broadcasting mode of the positioning auxiliary information according to the broadcasting mode indication information.

In this step, specifically, after receiving the broadcast indication message, the DU may determine the broadcast mode of the positioning assistance information according to the broadcast mode indication information.

In this way, the DU determines whether the broadcast mode of the positioning assistance information is periodic broadcast or broadcast based on a terminal request according to the broadcast instruction message and by combining the self condition, thereby realizing the determination of the DU on the broadcast mode of the positioning assistance information in the CU-DU scene.

Furthermore, after determining the broadcast mode of the positioning assistance information, the DU may also send a feedback message to the CU, where the feedback message carries broadcast result information of the positioning assistance information.

identification information of positioning auxiliary information which is periodically broadcasted;

It should be noted that the content of the broadcast result information is the same as that of the CU side broadcast result information, and the specific content of the broadcast result information in this embodiment may refer to the specific description of the broadcast result information by the CU side, which is not described herein again.

Thus, the DU determines the broadcast mode of the positioning auxiliary information by receiving the broadcast indication message sent by the CU and according to the broadcast mode indication information carried in the broadcast indication message, thereby realizing the determination of the DU to the broadcast mode of the positioning auxiliary information in the CU-DU scene.
