Description

Transmission mode reporting method, device, equipment and electronic medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and an electronic medium for reporting a transmission mode.

Background

Data transmission methods used in an IP (Internet Protocol) network include unicast, multicast, and broadcast. Unicast (unicast) refers to "one-to-one communication", i.e., data is sent from one device to one receiving device; multicast (Multicast)/Broadcast (Broadcast) refers to "one-to-many communication", that is, the same data is transmitted from one device to a plurality of receiving devices through a shared channel, a content copy technique, and the like. Multicast/broadcast has a higher efficiency of network resource usage than unicast. Multicast differs from broadcast in that: the multicast receiving device receives a specific multicast service content (i.e., data) by subscribing and/or joining a group, and terminates receiving the service content by unsubscribing and/or leaving the group; any device in the broadcast area or network can receive the broadcast content without subscribing or joining the group.

Currently, a 5G (5th generation) mobile communication system can support a unicast transmission mode. In addition, the 5G mobile communication system supports a multicast/broadcast data transmission scheme in order to support more services. Therefore, how to better manage these different data transmission schemes in the 5G mobile communication system is a problem to be solved.

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.

The data transmission modes adopted in the IP network include unicast, multicast and broadcast. Unicast (unicast) refers to "one-to-one communication", i.e., data is sent from one device to one receiving device; multicast (Multicast)/Broadcast (Broadcast) refers to "one-to-many communication", that is, the same data is transmitted from one device to a plurality of receiving devices through a shared channel, a content copy technique, and the like. Multicast/broadcast has a higher efficiency of network resource usage than unicast. Multicast differs from broadcast in that: the multicast receiving device receives a specific multicast service content (i.e., data) by subscribing and/or joining a group, and terminates receiving the service content by unsubscribing and/or leaving the group; any device in the broadcast area or network can receive the broadcast content without subscribing or joining the group.

Currently, a 5G mobile communication system can support a unicast transmission mode. In addition, the 5G mobile communication system supports a multicast/broadcast data transmission scheme in order to support more services. Therefore, how to better manage these different data transmission methods in the 5G mobile communication system is a problem to be solved.

Furthermore, in order to support more services, the 5G mobile communication system needs to dynamically adjust the service transmission mode (delivery mode or transport mode, i.e. unicast, multicast/broadcast) according to the service requirements (e.g. the number of users using a specific service at the same time) and the network resource usage. For example, for a specific video service transmitted by unicast, as the number of users watching the video increases, the network resources (e.g., bandwidth) required for transmitting the video becomes larger, and at this time, the 5G network may transmit the video by multicast/broadcast instead.

For 5G MBS (Multicast Broadcast Service), a 5G AN (Access Network) may configure or change a transmission mode (unicast or Multicast/Broadcast) adopted by AN side without notifying a core Network, so that the core Network does not know AN actually adopted transmission mode of the MBS Service in the entire Network, and there is no accurate statistical data for Network performance under a specific transmission mode (unicast or Multicast/Broadcast), which may result in that a Network management policy (e.g., a Service transmission mode related policy) cannot be set and optimized effectively.

In view of the above problems, embodiments of the present invention provide a transmission mode reporting method to implement accurate statistical analysis or prediction on network data and performance in a specific transmission mode, so as to set and optimize a network management policy more effectively.

The following description will be made by way of specific examples.

Fig. 1 is a flowchart of a transmission mode reporting method according to AN embodiment of the present invention, where the method is used for AN apparatus; as shown in fig. 1, the method may include the steps of:

s101, determining AN MBS transmission mode adopted by AN equipment.

Specifically, the MBS transmission scheme adopted by the AN device may include unicast, multicast, or broadcast transmission schemes.

S102, reporting the MBS transmission mode to a first CN (Core Network) device, so that the first CN device determines the corresponding MBS parameter at least according to the MBS transmission mode.

Specifically, the AN device reports the MBS transmission mode to the first CN device, which aims to make the first CN device perform accurate statistical analysis or prediction on the network data and performance in the MBS transmission mode, thereby more effectively setting and optimizing the network management policy.

As can be seen from the above embodiments, when determining the MBS transmission mode adopted by the AN device, the AN device may report the MBS transmission mode to the first CN, which is convenient for the first CN device to determine the corresponding MBS parameter at least according to the MBS transmission mode, thereby implementing more effective setting and optimization of the network management policy.

Further, based on the above method, when the above S101 is executed, the following implementation manners may be adopted, but are not limited to:

s1011, in the process of establishing a PDU (Protocol Data Unit) session or QoS (Quality of Service) flow of AN MBS, determining a transmission mode corresponding to specified wireless resources as the MBS transmission mode, wherein the specified wireless resources comprise AN resources used by the PDU session or QoS flow of the MBS; and/or

S1012, after the PDU session or QoS flow of the MBS is established and the transmission mode of the PDU session or QoS flow of the MBS is changed, determining the changed transmission mode as the MBS transmission mode.

Specifically, the transmission mode of the PDU session or QoS flow of the MBS is changed, which may mean changing from one transmission mode to another transmission mode. Such as: from unicast to multicast or broadcast, or from multicast or broadcast to unicast.

Further, based on the above method, AN MBS transmission mode adopted by the AN device is used to characterize a transmission mode corresponding to a radio resource used for transmitting MBS data between the AN device and a User Equipment (UE).

Specifically, the transmission mode corresponding to the radio resource used for transmitting the MBS data between the AN device and the UE may include a transmission mode such as unicast, multicast, or broadcast.

Specifically, the PDU session or QoS flow of the MBS herein refers to a QoS flow of a PDU session or PDU session carrying the MBS session. MBS data is transmitted in the form of MBS session (multicast/broadcast session), that is: one or more UEs establish MBS sessions with the network to receive MBS data. Further, the MBS session is carried over a PDU session or a QoS flow of a PDU session, i.e.: each UE receiving the same MBS service data (i.e., MBS session) is established with the network a PDU session, and the MBS service data is transmitted to each UE through the QoS stream of the PDU session. A QoS flow refers to a data flow that can guarantee a certain quality of service (e.g., satisfy a certain transmission rate, transmission delay, or error rate).

Further, based on the above method, when the above S102 is executed, the following implementation manners may be adopted, but are not limited to:

s1021, generating a first message, wherein the first message comprises an MBS session identifier, a transmission mode identifier for representing the MBS transmission mode or wireless resource information for representing the MBS transmission mode.

In particular, the first message may be an N2 message. Such as: the N2 message is a PDU Session Resource notification (Session Resource notification) message or an MBS Session Resource notification message.

In addition, the radio resource information may include: multicast Radio Access Bearer (Multicast Radio Access Bearer) information, Multicast Radio Bearer (Multicast Radio Bearer) information, Multicast quality of service (Multicast QoS) information, and the like.

When the transmission mode is determined as broadcast or changed from unicast to broadcast, the radio resource information corresponding to the transmission mode carried in the first message may be broadcast radio access bearer, broadcast radio bearer information, or broadcast service quality information.

When the transmission mode is determined to be unicast or changed from multicast (or broadcast) to unicast, the Radio resource information corresponding to the transmission mode carried in the first message may be unicast Radio access Bearer, unicast Radio Bearer information (i.e., Data Radio Bearer), or unicast service quality information.

Optionally, the first message may further include a QoS flow identifier and/or a TMGI (Temporary Mobile Group Identity); wherein, the QoS flow identification is used for the CN equipment to determine the MBS transmission mode of the MBS QoS flow; the TMGI is used for the CN equipment to determine the MBS transmission mode of the MBS service.

S1022, the first message is sent to the first CN device, so that the first CN device determines the MBS transmission mode of the MBS conversation according to the MBS conversation mark and the transmission mode mark, or determines the MBS transmission mode of the MBS conversation according to the MBS conversation mark and the wireless resource information.

It can be seen from the above embodiments that, the MBS transmission mode can be reported to the first CN device through the first message, so that the first CN device can determine the MBS transmission mode of the MBS session according to the MBS session identifier and the transmission mode identifier included in the first message, or determine the MBS transmission mode of the MBS session according to the MBS session identifier and the wireless resource information included in the first message, thereby improving the reliability of transmitting the MBS transmission mode.

Further, based on the above method, the method may further include the following steps:

s103, receiving the MBS parameter returned by the first CN equipment.

Optionally, the MBS parameters include one or a combination of:

MBS QoS parameters;

an MBS service zone;

MBS session management parameters;

the MBS analyzes the information.

S104, updating the MBS service parameter of the AN equipment according to the MBS parameter.

It can be seen from the above embodiments that, by receiving the MBS parameter returned by the first CN device, and updating the MBS service parameter of the AN device according to the MBS parameter, the requirements of the MBS service are better satisfied.

Further, based on the above method, when the above S104 is executed, the following implementation manners may be adopted, but are not limited to:

s1041, adjusting the service configuration of MBS session in the AN equipment according to MBS session identification and the MBS parameter;

configuring a wireless resource;

broadcasted MBS information;

MBS broadcast zone.

s1023, if the first CN equipment is an SMF (Session Management Function) entity, reporting the MBS transmission mode to the SMF entity; or the like, or, alternatively,

s1024, if the first CN device is an NWDAF (Network data analysis function) entity, reporting the MBS transmission mode to the NWDAF entity through an OAM (Operation Administration and Maintenance) entity.

Specifically, the SMF entities described in the embodiments herein further include an SMF entity dedicated to MBS services, for example: MB-SMF (Multicast Broadcast Session Management Function) entity.

As can be seen from the above embodiments, after determining the MBS transmission mode adopted by the AN device, the AN device may report the MBS transmission mode to the SMF entity or the MB-SMF entity; the MBS transmission mode can also be reported to an SMF entity NWDAF entity, thereby enriching the realization form of transmission mode reporting and improving the reporting efficiency of the MBS transmission mode.

Fig. 2 is a flowchart of a transmission mode reporting method according to an embodiment of the present invention, where the method is used for a first CN device; as shown in fig. 2, the method may include the steps of:

s201, receiving MBS transmission mode adopted by AN equipment sent by the AN equipment.

Specifically, the MBS transmission scheme adopted by the AN device may include unicast, multicast, or broadcast transmission schemes. And the MBS transmission mode adopted by the AN equipment is used for representing the transmission mode corresponding to the wireless resource used for transmitting the MBS data between the AN equipment and the UE.

S202, determining corresponding MBS parameters according to the MBS transmission mode.

Specifically, the MBS parameters include one or a combination of:

MBS QoS parameters;

an MBS service zone;

MBS session management parameters;

the MBS analyzes the information.

As can be seen from the above embodiments, the MBS transmission mode adopted by the AN device when the first CN device receives the data sent by the AN device may determine the corresponding MBS parameter according to the MBS transmission mode, thereby implementing more effective setting and optimizing the network management policy.

Further, based on the above method, when the above S201 is executed, the following implementation manners may be adopted, but are not limited to:

s2011, the first message is received.

Specifically, the first message may be an N2 message. Such as: the N2 message is a PDU Session Resource notification (Session Resource notification) message or an MBS Session Resource notification message.

S2012, if the first message includes MBS session identification and transmission mode identification for representing the MBS transmission mode, determining MBS transmission mode of MBS session according to the MBS session identification and the transmission mode identification; or the like, or, alternatively,

Specifically, the radio resource information may include: multicast Radio Access Bearer (Multicast Radio Access Bearer) information, Multicast Radio Bearer (Multicast Radio Bearer) information, Multicast quality of service (Multicast QoS) information, and the like.

It can be seen from the above embodiments that the MBS transmission mode sent by the AN device can be received through the first message, thereby improving the reliability of transmitting the MBS transmission mode.
