The resource indication method, the access network side device and the core network function provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
As described above, when the terminal receives the multicast service, in some scenarios, since the source serving cell supports transmitting the multicast service data by the shared channel mode, and the target cell after cell handover only supports transmitting the multicast service data by using the protocol data unit (Protocol Data Unit, PDU) Session (Session) mode, in order to implement the conversion of the multicast service from the shared channel mode to the PDU Session mode in the handover process, the PDU Session needs to be pre-established and the resources for transmitting the multicast service data are reserved for the PDU Session, which results in that each terminal receiving the same multicast service reserves a core network propagation resource, resulting in resource waste, so that the benefit of resource optimization brought by the shared channel mode is completely lost.
To solve the above technical problem, as shown in fig. 2, one embodiment of the present application provides a resource indication method 200, which may be performed by an access network side device (such as a base station), in other words, the method may be performed by software or hardware installed in the access network side device, and the method includes the following steps.
S202: first information from a core network function is received, the first information comprising quality of service QoS flow information in a PDU session and quality of service QoS flow information in the PDU session for transmitting multicast traffic data.
The embodiment does not limit the execution sequence of S202 and S204, and S202 may be before S204 and S204 may be after S204; it is also possible that S204 is before and S202 is after.
S204: core network resources for the PDU session are reserved, and the core network resources do not include part or all of QoS flow resources for transmitting multicast traffic, or include transmission resources, which are QoS flow resources for transmitting unicast traffic only or QoS flow resources for transmitting unicast traffic and multicast traffic.
The core network resource in this step may be a resource between the access network side device and the core network function, and the core network resource may include a QoS flow resource for transmitting unicast traffic of the PDU session (the QoS flow resource for transmitting unicast traffic may also be shared by multicast traffic to transmit multicast traffic data), and so on.
In practical application, the access network side device in this embodiment may further reserve core network resources for the shared channel, so that the core network may send multicast service data to the access network side device in a manner of sharing the channel, and the access network side device forwards the multicast service data to the terminal.
Optionally, the access network side device in this embodiment may further send resource indication information to the terminal, where the resource indication information is used to indicate an air interface resource for PDU session, where the air interface resource includes a resource for transmitting a multicast service, and the air interface resource may be a resource for transmitting a multicast service between the access network side device and the terminal.
Optionally, in the terminal switching process or after the switching is completed, the core network function may also establish a resource for transmitting the multicast service data for the PDU session with the access network side device, so that in the terminal switching process or after the switching is completed, the network side device sends the multicast service data to the access network side device through the PDU session.

In the embodiment of the application, since the reserved core network resources for PDU session do not include part or all of QoS stream resources for transmitting multicast service, resource waste can be avoided, and resource utilization rate is improved.
In the embodiment of the application, the access network side equipment does not contain resources for transmitting the multicast service when reserving resources for PDU (protocol data unit) session, but can contain resources for transmitting the multicast service when the access network side equipment and the terminal interactively reserve PDU session air interface resources; in the terminal switching process or after the switching is completed, the core network function can also establish the resources of the PDU session for transmitting the multicast service with the access network side equipment. The embodiment of the invention can simplify the transmission mode conversion in the multicast service switching and optimize the resource reservation mode.
S202 and S204 of embodiment 200 are generally performed before a cell handover occurs in the terminal, and the execution body of embodiment 200 may be a (source) access network side device of a source serving cell. Under the condition that the terminal is subjected to cell switching, the terminal can also access a target service cell, and the target service cell has (target) access network side equipment.
Optionally, in the case that the terminal performs cell handover, the embodiment 200 may further include the following steps: during or after the handover of the terminal, the (source) access network side device or the (target) access network side device sends at least one of the following to the core network function:
1) And the PDU Session identification, such as PDU Session ID.
2) A quality of service flow identity (Qos Flow Identity, QFI) of the PDU session for transmitting unicast traffic data, which QFI may be used for the core network function to send unicast traffic data to the access network side device via the PDU session.
3) And the QFI of the PDU session for transmitting the data of the multicast service can be used for a core network function to send the data of the multicast service to the access network side equipment through the PDU session.
4) The core network resource information of the multicast service may include the core network resources reserved in S204.
In this embodiment, in the case that the target access network side device sends at least one of the above 1) -4) to the core network function, the source access network side device may also interact with the target access network side device, so as to forward the above information to the target access network side device, and then forward the information to the core network function by the target access network side device.

Optionally, the QoS flow information mentioned in 3) above may be used to reserve transmission resources (including core network resources between the gNB and the MB-UPF and air interface resources), including at least one of the following:
1) QFI for a QoS flow for transmitting multicast service data, which QoS flow may be used for a core network function to transmit multicast service data to an access network side device through a shared channel instead of the PDU session described above.

Optionally, the foregoing embodiment may further include the following steps: and forwarding the data of the multicast service to the terminal by using the reserved QoS stream for transmitting the data of the multicast service through the PDU session in the switching process of the terminal or after the switching is completed.
In order to describe the resource indication method provided in the embodiments of the present application in detail, a specific embodiment will be described below, and as shown in fig. 3, the embodiment includes the following steps.
Step 1: a terminal (UE) sends a PDU Session ID and an MBS Session ID to an access and mobility management function (Access and Mobility Management Function, AMF) through an access network side device (gNB), the PDU Session ID and the MBS Session ID are used for requesting to a core network function to establish a PDU Session and an MBS Session, the PDU Session and the MBS Session are respectively used for transmitting unicast service data and multicast service data, and the UE may send the PDU Session ID and the MBS Session ID separately in two times.
Since the session management function (Session Management Function, SMF) for handling unicast traffic and the MB-SMF for handling multicast traffic may be co-located or separate, it will be described in what two cases: case one: the SMF for processing the unicast service and the MB-SMF for processing the multicast service are combined; and a second case: the SMF handling unicast traffic and the MB-SMF handling multicast traffic are separated.
Similarly, in some cases, a user plane function (User Port Function, UPF) for handling unicast traffic data forwarding is integrated with an MB-UPF for handling multicast traffic data delivery; in other cases, the UPF for handling unicast traffic data forwarding and the MB-UPF for handling multicast traffic data delivery are separate.
Step 2: AMF forwards PDU Session ID and MBS Session ID to SMF/MB-SMF. In case of separate SMF and MB-SMF, PDU Session ID is sent to SMF, MBS Session ID is sent to MB-SMF, or MBS Session ID is also sent to SMF and forwarded by SMF to MB-SMF.
Step 3: in the second case, the SMF transmits the PDU Session ID and the MBS Session ID to the MB-SMF; of course, in other embodiments, the SMF may just forward the MBs Session ID to the MB-SMF.
Step 4: in case two, the SMF sends, to the gNB via the AMF, one of the following received messages from the MB-SMF: MBS Session ID, PDU Session ID, qoS flow information of the multicast service transmitted through the shared channel, and QoS flow information for transmitting service data through PDU Session to the gNB.
The QoS flow information for transmitting service data through PDU Session includes QoS flow information in PDU Session and QoS flow information in PDU Session for transmitting multicast service data, where a QoS flow may transmit only unicast service, only multicast service, or both multicast service and unicast service. The QoS flow information includes QoS Flow Identification (QFI); qoS parameters may also be included; the quality of service QoS flow information in a PDU session for transmitting multicast traffic data may also contain a multicast indication indicating that the QoS flow in the corresponding PDU session is for transmitting multicast traffic data. The QoS flow information for transmitting the multicast service data by the shared channel (the data transmitted in the shared channel is distributed to a plurality of terminals by the gNB) is used for reserving transmission resources (including resources between the gNB and the MB-UPF and empty), and the QoS flow information may include a QoS flow identifier (multicast QFI for shared tunnel); qoS parameters may also be included. The SMF may allocate different qfs for multicast service data and unicast service data, or ensure that the two types of qfs are different by presetting different ranges for the two types of qfs.
Step 5: the SMF and the UPF interact to reserve PDU Session resource information for unicast service, wherein the PDU Session resource information only comprises transmission resources of unicast service QoS flow, and does not comprise part or all of transmission resources used for transmitting multicast service data QoS flow, or comprises transmission resources, and the transmission resources are transmission resources used for transmitting QoS flow of unicast service only or transmission resources used for transmitting QoS flow of unicast service and multicast service. I.e., the SMF interacts with the UPF to perform one of: qoS flow resources for transmitting unicast traffic (which may be shared for transmitting multicast traffic) are reserved for the PDU Session; qoS flow resources for transmitting the multicast traffic are not reserved.
Step 6: the gNB interacts with the terminal to establish air interface resources based on the obtained PDU Session related information and multicast service related information (QoS parameters and multicast QFI for PDU Session) transmitted by the PDU Session, establishes PDU Session core network resources with UPF based on the PDU Session related information, wherein the core network resources do not comprise part or all of QoS stream resources for transmitting multicast service or comprise transmission resources, and the transmission resources are QoS stream resources only for transmitting unicast service or QoS stream resources for transmitting both unicast service and multicast service.
It will be understood that steps 1 to 6 above are the flows before the terminal is handed over, and steps 7 to 9 described below are the flows during the handover or after the handover is completed. In practice, the gnbs in steps 1 to 6 and 7 to 9 may be different, e.g. the gnbs in steps 1 to 6 are (source) access network side devices of the source serving cell and the gnbs in steps 7 to 9 are (target) access network side devices of the target serving cell.
Step 7: the gNB performs the handover operation.
Step 8: the gNB transmits the PDU session ID to the AMF, may transmit unicast (QFI), and may also transmit multicast (multicast) QFI for PDU Session. The AMF forwards the PDU Session ID to the SMF, which may forward the unicast QFI, and may also forward multicast QFI for PDU Session.
Step 9: the SMF interacts with the UPF to update PDU Session resource information including unicast traffic stream transmission resources and transmission resources for transmitting multicast traffic data.
In the embodiment of the application, when the core network function and the access network side equipment reserve resources for PDU (protocol data unit) session, the resources for transmitting the multicast service are not included, but when the access network side equipment and the terminal interactively reserve PDU session air interface resources, the resources for transmitting the multicast service are included; during or after the terminal switching process, the core network function and the access network side equipment establish the resources of the PDU session for transmitting the multicast service. The embodiment of the invention can simplify the transmission mode conversion in the multicast service switching and optimize the resource reservation mode.
The resource indication method according to the embodiment of the present application is described in detail above in connection with fig. 2 and 3. A resource indication method according to another embodiment of the present application will be described in detail below with reference to fig. 4. It will be appreciated that the interaction of the core network function with the access network side device described from the core network function is the same as the description of the access network side device in the method shown in fig. 2 and 3, and the relevant description is omitted as appropriate to avoid repetition.
