Description

Service identification method and network entity and user device using the same

The present disclosure relates to a service identification method, and more particularly to a service identification method combining service and geographic area information, and a network entity and user apparatus using the same.

V2X (Vehicle to Everything) is a vehicle data transmission technology based on 3GPP communication protocol, including V2V (vehicle to vehicle), V2P (Vehicle to Pedestrian), and V2I (Vehicle to Infrastructure, vehicle and infrastructure communication, etc., this technology is mainly through the vehicle smart terminal equipment to achieve vehicle data transmission technology.

In order to exchange information between the vehicle and the outside world, the vehicle must periodically or triggerly inform relevant vehicles (such as its own location information and warning messages) to other vehicles around it. FIG. 1 is a schematic diagram showing that V2X messages are broadcast in different multimedia broadcast multicast services (MBMS) areas according to the current location of each vehicle. As shown in FIG. 1, the V2X messages are broadcast in the MBMS broadcast areas 111, 112, 113, 114, respectively, depending on where the vehicle is currently located 101, 102, 103, 104. That is to say, if the information exchange between the vehicle and the outside world is realized by the MBMS service, it is possible to generate a situation with overlapping broadcast areas.

However, according to the current standard of the 3GPP communication protocol TS 23.246, one MBMS service corresponds to only one temporary mobile group identity (TMGI). Also, although the MBMS broadcast area is composed of one or more sub-areas, the sub-areas cannot overlap each other. That is to say, a V2X service that must rely on multiple small areas that may overlap for transmission of information will conflict with the current standard. In other words, if different content belonging to the same service must use the same TMGI, it is not only necessary to distinguish it by flow identifier (FID), but also in areas with overlapping. Therefore, the current 3GPP communication protocol does not meet the requirements of the above V2X service for the current standard of MBMS service.

In addition, if the MBMS broadcast area is described only in units of cells, due to the difference between the target range of the V2X message and the MBMS broadcast range, it may cause the user device to receive too many irrelevant messages and cause it to be busy. Case. For example, FIG. 2 illustrates a schematic diagram of multiple vehicles broadcasting using a target range of V2X messages. Referring to vehicles B, C, D, and E shown in FIG. 2, these vehicles are all broadcast using the same broadcast area, so that vehicle A will receive the V2X messages sent by these vehicles. However, in fact, the vehicle A only falls on the target broadcast area of the vehicle B, and therefore does not need to receive the V2X messages transmitted by the vehicles C, D, and E.

Although the 3GPP standard has a location filter that can describe the target area more accurately and is included in the User Service Description (USD) for transmission to the user device, it is only applicable to files or strings. The transmission of the stream, and the relevant standards have not been set in the group communication. Secondly, in order to describe the target area more accurately, although more broadcast areas can be planned, the user equipment must frequently switch between different broadcast areas and update the relevant USD. If the transmission of USD is delayed, it will cause delay in receiving V2X messages, and may also cause loss of important V2X messages.

Therefore, how to provide a V2X service compatible with the current standards of the MBMS service of the 3GPP communication protocol and at the same time improve the execution performance of the V2X message delivery is one of the topics of interest to those skilled in the art.

In view of this, the present disclosure provides a service identification method and a network entity and user apparatus using the same.

The present disclosure provides a service identification method suitable for a user device. The method includes, but is not limited to, including: receiving a first broadcast service identifier of a broadcast service, wherein the first broadcast service identifier includes both service identification information and area identification information, the service identification information is associated with the first service, and the area identification information Corresponding to the target area corresponding to the first service; determining, according to the service identification information in the first broadcast service identifier, whether the first service is a service of interest of the user device; in response to determining that the first service is a user device The interest service determines whether the user device is located in the target area according to the area identification information in the first broadcast service identifier; and monitors the resource corresponding to the first broadcast service identifier in response to determining that the user device is located in the target area Block the broadcast service content of the broadcast service.

The broadcast service corresponding to the service identifier is negligible or non-negligible, which not only improves the performance of message delivery, but also avoids the delay of message reception. In addition, for a plurality of possible overlapping target areas belonging to the same service, the broadcast service identifiers have the same service identification information, but the area identification information area separates different target areas, so that the broadcast service identification code can also The message is transmitted in overlapping areas to achieve a V2X service that is compatible with the current MBMS service standard of the 3GPP communication protocol.

Please refer to FIG. 5. FIG. 5 is a flowchart of a service identification method proposed from the perspective of a network entity according to one of the exemplary embodiments of the present disclosure.

In step S510, the network entity receives a broadcast service identifier configuration request through the receiver. In this embodiment, the network entity is described by the BMSC, which is located in the core network and will perform authentication/authorization of the content provider and configure the broadcast service identifier desired by the content provider. The application service server providing the MBMS service transmits a broadcast service identifier configuration request to the BMSC, so that the BMSC can configure the broadcast service identifier according to the broadcast service identifier configuration request.

In this embodiment, the broadcast service identifier configuration request includes at least the following information: at least one service information and corresponding target area information.

The broadcast service identifier requested by the application service server can be implemented based on the TMGI format of FIG. Therefore, this broadcast service identification code is compatible with the TMGI of the MBMS service in the 3GPP standard. The service information in the broadcast service identifier configuration request is used to assist the network entity in configuring the service identification information of the broadcast service identifier, and the service identification information is used to identify the MBMS service. MBMS services can refer to services such as V2V, V2I, V2P or V2N in V2X vehicle data transmission technology, or for specific services such as coordinated crossroad collision avoidance systems, front collision warnings and cornering speed warnings.

In step S520, the network entity configures at least one broadcast service identifier in response to the broadcast service identifier configuration request. In this embodiment, in addition to the service identification information for identifying the MBMS service, the network entity generates the area identification information based on the geographic area information based on the TMGI format defined in FIG. 4 to configure the broadcast service identification code. Thus, FIG. 6 is an MBMS service identification code 610 in accordance with another exemplary embodiment of the present disclosure, which further defines sections 411 and 412 in the MBMS service identification code 410 based on the TMGI format defined in FIG. Schematically, section 412 is provided with region identification information associated with the target area. The area identification information is used to identify a target area corresponding to the broadcast service content broadcasted based on the MBMS service.

Referring to FIG. 6, the MBMS service identification code 610 in FIG. 6 includes a section 611 carrying service identification information and a section 612 carrying area identification information. The section 611 is the same as the section 411 shown in FIG. 4, and the service identification information carried in the section 611 is a bit string identifying the MBMS service, which may be a fixed length or a variable length. The service identification information carried in the section 611 can be configured according to the service information in the broadcast service identifier configuration request.

The area identification information carried in the section 612 is a bit string identifying the geographic area information, which can be configured according to the target area information in the broadcast service identifier configuration request. It should be noted that the target area may be at least a preset range area, at least one road section or at least one road fork or at least one MBMS service area identity (SAIs) or at least one honeycomb identification code ( The area to which cell IDs) corresponds.

In this embodiment, if the target area is a preset range area, where the preset range area may be a specific coverage area, the area identification information carried in the section 612 may include an area type and an area associated with the target area. Information such as parameters are described, but the disclosure of geographic area information is not limited to this. It should be noted that the type of the area included in the area identification information carried in the section 612 and the corresponding area description parameter may be changed according to the user setting. For example, the above-mentioned area type is, for example, the area shape of the target area (for example, a circle or a square), and the area description parameter can define the size and position of the target area. More specifically, the area type can be mapped to a determination function for defining the area shape, and the user equipment can obtain the coverage of the target area by using the judgment function and the area description parameter. In other words, the determination function corresponding to the area type can be used to determine whether the user device that received the broadcast service identification code is located in the target area according to the area description parameter.

In another embodiment, assuming that the target area is a road section or a road fork, the area identification information carried by the section 612 may include a road section identification code or a road fork identification code associated with the target area. Therefore, the user equipment can determine whether it is located in the target area according to its current location, that is, whether it is located on the road section represented by the road section identification code or the road fork identification code or near the fork of the road. In another embodiment, assuming that the target area is an area corresponding to the MBMS SAIs or cell IDs, the area identification information carried in the section 612 may include MBMS SAIs or cell IDs associated with the target area. Therefore, the user equipment can determine whether it is located in the target area according to the MBMS SAIs or cell IDs in which it is currently located, that is, whether it is located in the area represented by the MBMS SAIs or the cell IDs in the area identification information.

In other words, based on FIG. 4 in conjunction with the TMGI format of FIG. 6, the network entity responds to the broadcast service identifier configuration request, and each of the broadcast service identifiers can be configured to include the service identification information (ie, the bits carried in the segment 611). The string is associated with the area identification information (i.e., the bit string carried in section 612) to assist the UE in confirming the MBMS broadcast service and message associated therewith.

In the embodiment of the present disclosure, for a broadcast service identifier having the same service but different target areas, the network entity may configure the service identification information corresponding to the service according to the service information for at least one broadcast service identifier of the same service. So that the broadcast service identifiers corresponding to the same service have the same service identification information. Moreover, the network entity further configures and corresponds to the area identification information of the different target areas by the at least one broadcast service identifier having the same service to distinguish the same service but corresponding to at least the different broadcast service content. A broadcast service identifier. It is to be noted that, since the at least one broadcast service identification code has configured the area identification information respectively corresponding to each of the different target areas, each of the different target areas may overlap each other. In this way, the broadcast service identification code is not only required to be distinguished by the stream identification code, but also transmitted in an overlapping area.

After the network entity completes the configuration of the broadcast service identifier, in step S530, the network entity may transmit the at least one broadcast service identifier configured by the network through the transmitter circuit, where the broadcast service identifier includes at least one service identifier. Information and its corresponding area identification information. Further, the network entity may transmit the configured broadcast service identifier to the application server, or transmit the configured broadcast service identifier to one or more base stations, the one or more bases. The station delivers the broadcast service identifier to the user device.

Next, FIG. 7 is a flowchart of a service identification method proposed from the perspective of a UE in accordance with one of the exemplary embodiments of the present disclosure.

In step S710, the UE reads the system information block (SIB) and the control information contained in the multicast control channel (MCCH) to determine whether the first broadcast service identifier received by the receiver is new. Broadcast service identifier. In this embodiment, the first broadcast service identifier may be in the TMGI format defined by the disclosure or not in the TMGI format defined in the disclosure. When the first broadcast service identifier conforms to the TMGI format defined by the disclosure, the first broadcast service identifier includes the service identification information and the area identification information, the service identification information is associated with the first service, and the area identification information is associated with the corresponding The target area of the first service.

If the UE does not receive the first broadcast service identifier, the UE proceeds to step S710 to continuously update the received system information block and the information on the multicast control channel, and continuously determines whether the first broadcast service identifier has been received. code.

On the other hand, if the UE receives the first broadcast service identifier, the UE proceeds to step S720 to parse the first broadcast service identifier. In step S720, the UE determines whether the first broadcast service identifier conforms to a specific TMGI format, and determines whether the first service is the UE's interest service according to the service identification information in the first broadcast service identifier.

In this embodiment, the UE has a pre-configured list of identifiers of interest. The list of identifiers of interest includes a plurality of second broadcast service identifiers. It should be noted that the format of the second broadcast service identifier may be the TMGI format described in the current standard of the 3GPP communication protocol TS 23.003 (refer to the TMGI format shown in FIG. 3), but the disclosure does not There is a limit as long as the second broadcast service identifier includes information related to its service. Based on the service identification information in the first broadcast service identifier, the UE may determine whether the first service meets the second service associated with any one of the plurality of second broadcast service identifiers to determine whether the first service is a UE. Interested in the service. If yes, go to step S730.

In step S730, the UE determines whether the UE is located in the target area according to the area identification information in the first broadcast service identifier in response to determining that the first service is the interest service of the UE.

In this embodiment, if the target area is a preset range area, the area identification information includes an area type associated with the target area and an area description parameter associated with the area type. The area type is mapped to a judgment function, and the judgment function is used to determine whether the UE is located in the target area according to the area description parameter. The UE needs to obtain its current current location to determine whether the current location of the UE is located in the target area according to the type of the region and its corresponding judgment function.

For example, please refer to FIG. 8. FIG. 8 is an MBMS service identifier 810 according to one of the exemplary embodiments of the present disclosure. The MBMS service identifier 610 is further based on the TMGI format defined in FIG. A schematic diagram of the definition of section 612 in it. In the present embodiment, the section 811 also carries the service identification information, and the section 812 also carries the area identification information. It should be noted that the area identification information received by the UE includes the area type 8121, and the location identifier 8122 of the target area for indicating the area description parameter and the size parameter 8123 of the target area.

The area type 8121 is the area shape of the target area. In an embodiment, when the area type 8121 is circular, the UE may obtain a corresponding circular determination function according to the area type 8121, and set the position identification code 8122 of the target area in the area description parameter and the size of the target area. Parameter 8123 is substituted into the judgment function. Based on this, the determination function for determining whether the current location of the UE is located in the target area can be expressed as: Formula (1) In formula (1), Representing the current location of the UE, Represents the reference center location of the target area, Obtained based on the location identification code 8122 of the target area, The radius representing the circle is obtained from the size parameter 8123 of the target area, and S represents the scaling factor. When the current position of the UE satisfies the judgment function shown in the formula (1), it can be determined that the UE is located in the target area, and vice versa.

In another embodiment, if the area type 8121 is a square, the UE may obtain a corresponding square judgment function according to the area type 8121, and set the position identification code 8122 of the target area in the area description parameter and the size parameter of the target area. 8123 is substituted into the judgment function. Based on this, the determination function for determining whether the current location of the UE is located in the target area can be expressed as: Formula (2) In formula (2), Representing the current location of the UE, Represents the reference center location of the target area, Obtained based on the location identification code 8122 of the target area, The unit length representing the square is obtained from the size parameter 8123 of the target area, and S represents the scaling factor. When the current position of the UE satisfies the judgment function shown in the formula (2), it can be determined that the UE is located in the target area, and vice versa.

In other embodiments, if the target area is a road section or a road fork, the area identification information received by the UE includes a road section identifier or a road fork identification code associated with the target area. Therefore, the UE can obtain the road information of the current location, and determine whether the road information conforms to the road section identification code or the road fork identification code. If the target area is the area corresponding to the MBMS SAIs or the cell IDs, the area identification information received by the UE may be MBMS SAIs or cell IDs, or the MBMS SAIs or cell IDs are calculated by other functions (such as a hash function). The output value, the UE can determine whether it is located in the target area by its current MBMS SAIs or cell IDs.

Then, if the UE is not located in the target area, indicating that the UE can ignore the broadcast service corresponding to the first broadcast service identifier, the UE returns to step S710 to continuously update the received system information block and the multicast control channel to determine Is there a new first broadcast service identifier?

On the other hand, if the UE is located in the target area, proceed to step S740, the UE will continuously monitor and acquire a broadcast service content of the broadcast service via the resource block corresponding to the first broadcast service identifier to obtain a corresponding The message for the MBMS broadcast service.

Going back to step S720, if the UE determines that the first broadcast service identifier does not conform to the specific TMGI format, or determines that the first service is not the UE's service of interest, then step S750 is performed.

In step S750, the UE determines whether the first broadcast service identifier is the UE's interest service by using the system information block, the multicast control channel, and the user service description (USD). In this embodiment, since the USD is transmitting information about the broadcast multicast service to the UE that receives the MBMS service (eg, source Internet Protocol (IP) address, destination IP address, port, and TMGI The UE can determine whether the first broadcast service identifier is the UE's service of interest through the USD.

If it is determined in step S750 that the first broadcast service identification code is not the interest service of the UE, the UE returns to step S710 to continuously update the received system information block and the multicast control channel, and determines whether there is a new first broadcast service. Identifier.

On the other hand, if it is determined in step S750 that the service identification information in the first broadcast service identification code is displayed as the service of interest of the UE, proceeding to step S740, the UE will continuously monitor the resource area corresponding to the first broadcast service identifier. Blocking a broadcast service content of the MBMS service to obtain a message corresponding to the MBMS service.

In summary, the service identification method and the network entity and the user device using the method are provided by the network entity, and the network entity can help the content of the broadcast service identifier by including the service identification information and the area identification information. The UE quickly confirms that the broadcast service corresponding to the broadcast service identifier is negligible or non-negligible, which not only improves the performance of message delivery but also avoids delay in receiving the message. In addition, for a plurality of possible overlapping target areas belonging to the same service, the broadcast service identifiers have the same service identification information, but the area identification information area separates different target areas, so that the broadcast service identification code can also The message is transmitted in overlapping areas to achieve a V2X service that is compatible with the current MBMS service standard of the 3GPP communication protocol.
