For the services required by the above group service scenario, in the prior art, how to charge for the network service used by the multicast group user has no specific scheme yet.
In order to solve the above problems, the present invention provides a charging method, a device, a network entity and a medium. The method and the device are based on the same inventive concept, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.
It should be noted that, the charging method of the present invention can implement a differentiated charging scheme based on the existing 3GPP protocol session management function (Session Management Function, SMF) entity and the session management function (Multicast/Broadcast Session Management Function, MB-UPF) entity data for the group session, the group user related traffic, the duration, and the quality of service.
Referring to fig. 1, a specific flow of multicast joining is briefly introduced, where an MB-UPF entity may record MBs session usage flow, and an SMF entity may receive multicast joining join (e.g. request)/leave information sent by a terminal UE, and through the join/leave information, the SMF entity may know what time period the UE performs multicast service. When the UE is performing a multicast service, the SMF entity knows which UEs are transmitting multicast data in the unicast tunnel individual delivery (in which case the base station does not support MBS, the UPF has unicast traffic data) and which times are transmitting multicast data in the shared tunnel (in which case the base station supports MBS), and the multicast joining procedure can support the forward (user) charging scheme and the backward (application function (Application Function, AF) entity) charging scheme of the present invention. Referring to fig. 1, the specific steps of multicast joining are as follows:
① The UE obtains MBS multicast session information through the service announcement Service Announcement.
Wherein Service Announcement is sent by the service server to the UE. Optionally, the MBS multicast session information includes a region;
② The UE initiates a multicast join procedure through a protocol data unit (Protocol Data Unit, PDU) session.
Specifically, the UE sends a PDU session establishment request (PDU session establishment request) message or a PDU session modification request (PDU session modification request) message to an SMF entity of the 5G core network (5 GC), where the message carries an MBS session ID.
③ An access and mobility management function (ACCESS AND Mobility Management Function, AMF) entity identifies the UE based on the PDU session establishment/modification request message and sends the UE identity to the SMF entity; the SMF entity receives the multicast joining request (such as PDU session establishment/modification request message) of the UE, and searches the MB-SMF entity session information through the network storage function (NF Repository Function, NRF) entity according to the MBS session ID in the message. The SMF entity authenticates the multicast joining request of the UE, establishes MBS session after passing the authentication, and obtains MBS session configuration information.
Wherein, the MB-SMF entity session information may include: multicast quality of service (Quality of Service, qoS) flows, multicast addresses, unicast QoS flows corresponding to multicast, where the unicast QoS flows corresponding to multicast are used for transmitting MBS data for Users (UEs) by base stations that do not support MBS.
④ The SMF entity maps out QoS parameters required for the associated quality of service flows Associated QoS flow according to the MBS session configuration information.
⑤ The SMF entity sends a multicast setup request to NG-RAN (5G radio access network) in PDU session modification procedure, the request including MBS session ID and area session ID.
⑥ If the NG-RAN supports MBS, according to MBS session ID, requesting the MB-SMF entity to establish shared tunnel, and opening multicast data of the MB-UPF entity to send to the dedicated tunnel of the NG-RAN.
⑦ If the NG-RAN does not support MBS, a media channel is established between the SMF entity/UPF entity and the MB-SMF entity/MB-UPF entity, and the SMF entity/UPF entity sends the multicast data to the UE through Associated QoS flow.
As shown in fig. 2, a charging method according to an embodiment of the present invention is applied to, that is, executed by, a network entity. Specifically, the method may include:

Based on this, the step 201 may include:
step 201a, receiving a multicast joining request message sent by a terminal, wherein the multicast joining request message comprises an MBS session ID;
here, the multicast join request message may be PDU session establishment/modification request message.
Step 202a, searching MB-SMF entity session information through a network storage function NRF entity according to MBS session ID;
The step corresponds to ③ in the multicast joining flow, and the SMF entity searches the MB-SMF entity session information through the NRF entity according to the MBS session ID.
Alternatively, the MB-SMF entity session information may include: multicast quality of service (Quality of Service, qoS) flows, multicast addresses, unicast QoS flows corresponding to multicast, where the unicast QoS flows corresponding to multicast are used for transmitting MBS data for Users (UEs) by base stations that do not support MBS.
Step 203a, after the multicast joining request message passes the authentication, obtaining the MBS session configuration information by establishing an MBS session.
Before the authentication, the AMF entity identifies the UE based on the multicast join request message and sends the UE identity to the SMF entity, so that the SMF entity can know which UE to authenticate the multicast join request message sent for when authenticating the multicast join request message. Wherein, the MBS session configuration information is used for checking the session list.
In the case that the charging object is a terminal participating in a group session, and in the case that the network entity is an SMF entity, the preset charging mode includes one of the following:
a charging mode I for borrowing unicast tunnel traffic based on a group session used by a terminal;
Charging mode II based on the duration of the terminal participating in the group session;
Charging mode III based on service using duration of the terminal unicast tunnel borrowed by the group session;

In an alternative embodiment, in a case that the preset charging mode is the charging mode one; the method of the embodiment of the invention further comprises the following steps:
Under the condition that the wireless access network does not support MBS, mapping the multicast QoS flow to the unicast QoS flow, and transmitting terminal multicast data through the associated protocol data unit PDU session;
It should be noted that, for the case where the NG-RAN does not support MBS, the MB-UPF entity to UPF entity uses the shared tunnel QoS Flow to transmit multicast data.
And acquiring the group session borrowing unicast tunnel traffic used by the terminal through a user plane function UPF entity, wherein the group session borrowing unicast tunnel traffic used by the terminal is obtained by the UPF through the group session traffic and the unicast tunnel traffic calculation.
Optionally, the SMF entity configures usage reporting rules (Usage Reporting Rules, URR) of the group session borrowing unicast tunnel for separately recording the group session borrowing unicast tunnel traffic used by the terminal.
In another optional embodiment, in a case that the preset charging mode is the charging mode two; the method of the embodiment of the invention further comprises the following steps:
Acquiring the time of the terminal joining the group session and the time of the terminal leaving the group session through the non-access layer message and MBS session ID of the PDU session sent by the terminal;
Here, the Non-Access Stratum (NAS) message of the PDU session may be PDU session establishment/modification request message, i.e., the terminal joins the MBS multicast session through PDU session establishment/modification request message. The terminal leaves the MBS multicast session through PDU session modification request messages.
Optionally, the NAS message of the PDU session carries a container Requested MBS container, which contains contents including:
Multicast/broadcast service behavior MBS operation (2 bits), "01" is join, indicating joining MBS multicast session; "10" is leave, indicating that the MBS multicast session is left;
MBS session ID type Type of MBS session ID (2 bits), "01" is temporary mobile group identity (Temporary Mobile Group Identification, TMGI); "10" is an IPv4 address, and "11" is an IPv6 address;

and obtaining the duration of the terminal participating in the group session according to the time of the terminal joining the group session and the time of the terminal leaving the group session.
And the SMF entity records the time node of the UE join/leave according to the MBS session ID, and calculates the duration of the terminal participating in the group session.
In yet another alternative embodiment, in the case that the preset charging mode is the charging mode three; the method further comprises the steps of:
Acquiring starting time and stopping time of a unicast tunnel in a group session process;
When the unicast tunnel is started initially, the SMF entity needs to configure the unicast QoS flow (individual QoS flow); when the unicast tunnel is switched to the shared tunnel, the SMF entity needs to configure a UPF entity stop data forwarding instruction for instructing the UPF entity to stop forwarding the multicast data.
And obtaining the service use duration of the terminal unicast tunnel borrowed by the group session according to the starting time and the stopping time of the unicast tunnel.
It should be noted that the SMF entity itself knows when to start and stop the use of the unicast tunnel, so that it can determine the service usage duration of the terminal unicast tunnel borrowed by the group session.
In yet another alternative embodiment, in the case that the preset charging mode is the fourth charging mode; the method further comprises the steps of:
Obtaining an associated PDU session context, the associated PDU session context comprising: multicast service related information;
It should be noted that, the SMF entity is responsible for managing and maintaining multicast service information of terminal granularity, that is, the SMF entity records multicast service related information in the associated PDU session context.
And obtaining QoS of the terminal joining the group session according to the multicast service related information, wherein the QoS of the terminal joining the group session comprises a multicast QoS stream and a unicast QoS stream corresponding to the multicast.
The multicast service related information may be a multicast service context, in which terminal related information is recorded. The terminal related information comprises a multicast QoS stream and a unicast QoS stream corresponding to the multicast. The method of the invention can support the information splitting and independent statistics of differentiated traffic, duration and the like based on QoS.
Alternatively, in the case that the charging object is the server participating in the group session, the network entity is an MB-SMF entity; accordingly, the step 201 may include:
step 201b, obtaining group basic information corresponding to the charging object through establishing an MBS session, where the group basic information at least includes:
each MBS session corresponds to the allocated temporary mobile group identification TMGI;
Session context for each MBS session;
each MBS session corresponds to the identity of the established shared tunnel.
Here, the group basis information is used to core a dialog sheet. The MB-SMF entity is responsible for multicast session management at the service granularity, i.e. session establishment per MBs session.
Based on this, the preset charging mode includes one of the following:
Charging mode V based on the flow data used by the group record;
Charging mode six of session duration recorded based on group session online time;
a seventh charging mode based on the group service usage duration of the group session activation/deactivation record;
charging means eight based on the recorded QoS of the group session.
In an optional embodiment, in a case where the preset charging manner is the charging manner five, the method in the embodiment of the present invention further includes:
Sending a Packet Forwarding Control Protocol (PFCP) session establishment request message to a user plane function (MB-UPF) entity of a multicast/broadcast service, wherein the PFCP session establishment request message is used for establishing a PFCP session for an MBS session, and the PFCP session establishment request message comprises an MBS session ID;
Here, the MB-UPF entity interacts with the MB-SMF entity through the N4MB interface, and the MB-SPF entity establishes a PFCP session for an MBs session by sending a PFCP session establishment request (PFCP Session Establishment Request message) message to the MB-UPF entity.
And obtaining the flow data used by the group record through the MB-UPF entity, wherein the flow data used by the group record is the multicast flow data of the associated MBS session ID.
It should be noted that, the MB-UPF entity receives the multicast traffic data of the associated MBs session ID, and records the traffic sum of the users in each multicast group.
Here, the flow data used by the group record may generate a ticket according to a threshold, for example, when the flow data used by the group record exceeds a first threshold, the ticket is charged according to a first rule; when the flow data used by the group record exceeds the first threshold value and is smaller than the second threshold value, charging is carried out according to the second rule, and the like.
In another optional embodiment, in a case where the preset charging manner is the charging manner six, the method further includes:
in the group session process, acquiring the starting time and the deadline for establishing a shared tunnel;
It should be noted that the MB-SMF entity is responsible for MBs session management, selects and configures the MB-UPF entity to establish the shared tunnel, and records the start time and the deadline for establishing the shared tunnel.
And obtaining the session duration of the group session online time record according to the starting time and the deadline of the establishment of the shared tunnel.
Specifically, when a terminal joins a multicast session, the SMF entity of the terminal establishes a session with the MB-SMF entity of the MBS session, refer to step 3 in fig. 3. For a UE leaving the multicast session, refer to step 12 in fig. 4, when the last joining UE on the SMF entity leaves, the session between the SMF entity and the MB-SMF entity is released. When the session is released between all the SMF entities and the MB-SMF entity, the MB-SMF entity stops the data transmission of the MB-UPF entity.
So through the two procedures described above, the MB-SMF entity knows whether there is a UE in the multicast session, but does not know specific UE information.
Here, the session duration recorded by the group session online time may generate a ticket according to a threshold, for example, after the group session duration exceeds a third threshold, charging according to a third rule; and when the group session duration exceeds the third threshold value and is smaller than the fourth threshold value, charging according to a fourth rule and the like.
In yet another optional embodiment, in case the preset charging manner is the charging manner seven, the method further includes:
And determining the group service use duration of the group session activation/deactivation record through MBS message transmission response messages sent by the access and mobility management function AMF entity.
Here, the MB-SMF entity itself is aware of the activation (see fig. 5) and deactivation events (see fig. 6). When the MB-UPF entity receives the downlink multicast group data or the AF entity sends a multicast activation request (containing TMGI), and when the MB-UPF entity detects that there is no downlink data user or the AF entity sends an MBS deactivation request (TMGI) through a network opening function (Network Exposure Function, NEF) entity.
In still another optional embodiment, in a case where the preset charging manner is the charging manner eight, the method of the embodiment of the present invention further includes:
