Please refer to FIG. 2. FIG. 2 is a flowchart of a method for receiving resource information provided by an embodiment of the present application. The method is applied to a terminal, as shown in FIG. 2, and includes the following steps:

Step 201: Send a measurement report for handover to the source network side device.

The above measurement report may be a measurement report used for the terminal multi-source network side device to switch to the target network side device. And the above-mentioned target network side device may be selected by the source network side device.

For example, the terminal sends a measurement report to the source network side device. After the source network side device receives the measurement report, it can select the target network side device and send a handover request message (such as a Handover Request message) to the target network side device.

Further, the above-mentioned handover request message may also carry PDU session related information, such as at least one of PDU Session ID (PDU Session ID), Flow Identifier (QFI), Quality of Service (QoS) related information, PDU session core network uplink channel information, etc. one.

Step 202: Receive resource information, where the resource information is used to indicate a multicast air interface resource for the target network side device to transmit multicast service data.

Step 202 may be to receive resource information sent by the target network side device through the source network side device, or through the core network function and the source network side device.

Further, the above resource information may be sent through a handover command, which of course is not limited in this embodiment of the present application, for example, it may also be sent through a resetting message.

In the embodiment of the present application, after sending the measurement report, the multicast air interface resources used by the target network side device to transmit the multicast service data can be quickly obtained through the above steps, thereby improving the efficiency of obtaining the multicast air interface resources. The switching efficiency of the multicast service can be improved.

As an optional implementation manner, after the measurement report for handover is sent to the source network side device, the method further includes:

Get idle state indication;

According to the idle state indication, enter the idle state or stop sending the handover confirmation message to the target network side device.

The acquisition of the idle state indication may be obtained based on the above resource information, for example: the above resource information explicitly or implicitly indicates the above idle state indication.

The above idle state indication may be used to instruct the terminal to enter the idle state, so that after the terminal obtains the indication, it may enter the idle state or stop sending a handover confirmation message to the target network side device, so as to realize the reception of multicast service data in the idle state, Or in the case that the handover is not completed, the multicast service data is received.

In addition, if the terminal is instructed not to enter the idle state, the terminal may enter the connected state, or may send a handover confirmation message to the target network side device.

Optionally, the obtaining the idle state indication includes at least one of the following:

receive redirection messages;

Receive the information on the transmission mode of the target multicast service;

The resource information does not include PDU session information.

The above-mentioned target multicast service transmission mode information may be included in the above-mentioned resource information, and the above-mentioned target multicast service transmission mode information may be a point-to-multipoint transmission mode. Of course, this is not limited, for example: it may be predefined in the protocol. information on the transmission mode of multicast services.

Further, when at least one of receiving the redirection message, receiving the target multicast service transmission mode information, and the resource information not including the PDU session information is satisfied, it may be determined that the terminal is instructed to enter the spatial state.

It should be noted that, in some embodiments, the above-mentioned idle state indication has two indication states, one of which indicates entering the idle state, and the other indicating not entering the idle state. For example, if the above resource information includes PDU session information, it indicates not to enter the idle state, or if the above resource information does not include information on the transmission mode of the target multicast service, it indicates not to enter the idle state, and so on.

Optionally, after the terminal enters the idle state, the method further includes:

The multicast service data sent by the target network side device is received at the multicast air interface resource.

In this embodiment, it can be realized that the terminal can receive multicast service data sent by the target network side device in the idle state. For example, the target network side device can send multicast service data to the terminal through a multicast shared channel or a dedicated channel. Of course, this is not limited. For example, it can also receive the data sent by the target network side device in the idle state by other methods defined by the protocol. Multicast service data.

In this embodiment, since the multicast service data sent by the target network side device is received in the idle state, the switching efficiency can be improved, because there is no need to perform PDU session switching, and the power consumption of the terminal can also be saved.

In this embodiment of the present application, a measurement report for handover is sent to the source network side device; resource information is received, where the resource information is used to indicate the target network side device to transmit multicast air interface resources for multicast service data.

For the above resource information, reference may be made to the corresponding description of the embodiment shown in FIG. 2 , which will not be repeated here.

In this embodiment, the above steps can improve the efficiency of the terminal acquiring the multicast air interface resources.

As an optional implementation manner, the above-mentioned reservation of multicast air interface resources according to the existence of multicast services in the terminal includes:

Multicast air interface resources are reserved according to the PDU session information sent by the source network side device, and the PDU session information is used to indicate that the terminal has a multicast service.

The foregoing PDU session information may be used to indicate that the terminal has a multicast service, and the PDU session information may be used implicitly or explicitly to indicate that the terminal has a multicast service.

For example, according to the above-mentioned PDU session information sent by the source network side device, the multicast air interface resources are reserved, including:

Multicast air interface resources are reserved according to the specified core network uplink channel resource information or specified flow identification information or specified quality of service identifier (QoS Identifier, QI) included in the PDU session information.

Wherein, the designated core network uplink channel resource information or designated flow identifier information or designated service quality identifier included in the above-mentioned PDU session information can determine that the terminal has a multicast service, and then reserve multicast air interface resources.

The above-mentioned designated QoS identifier can be the designated 5G QoS Identifier (5G QoS Identifier, 5QI) defined in the designated 5G system. Of course, it can also be applied to 6G, and the above designated QoS identifier can be the designated service defined in the designated 6G system. Quality logo.

In this embodiment, since the multicast service has only downlink data but no uplink data, the core network function (such as SMF or UPF) uses the specified core network uplink channel resource information, such as the core network uplink channel, during the process of establishing a multicast-related PDU session. The resource information (CN UL Tunnel Info) is all 0s or all 1s, or uses the specified QoS flow identifier or the indicated QI to represent the multicast service.

Wherein, the above-mentioned designated core network uplink channel resource information or designated flow identification information or designated service quality identification may be a protocol agreement, or pre-configured, etc., which is not limited, and the above designated core network uplink channel resource information or designated flow identification information Alternatively, the specified QoS identifier can also be understood as the specific core network uplink channel resource information or the specific flow identifier information or the specific QoS identifier.

In the above embodiment, since the multicast air interface resources are reserved according to the PDU session information sent by the source network side device, there is no need to add other messages to reserve the multicast air interface resources, so as to save resource overhead.

As an optional embodiment, the above method also includes:

An idle state indication is provided to the terminal.

Optionally, the providing an idle state indication to the terminal includes at least one of the following:

send a redirect message;

Send target multicast service transmission mode information;

The resource information does not include at least one item of PDU session information.

As an optional implementation manner, the reserving multicast air interface resources includes:

Reserving multicast air interface resources according to multicast service information; or

Multicast air interface resources are reserved according to the pre-configured information.

Wherein, the above-mentioned multi-play service information may be sent by the core network function, of course, this is not limited, for example: it may also be sent by the source network side device.

The above-mentioned multicast service information may include at least one item of a multicast service identifier, multicast service QoS information, and the like.

The foregoing reserving multicast air interface resources according to the multicast service information may be reserving multicast air interface resources matching the multicast service.

The above-mentioned reservation of multicast air interface resources according to the pre-configured information may be to reserve air interface multicast resources by using a pre-configured scheme based on the judgment that the terminal has a multicast service in the case that the multicast service information is not obtained. For example, for example, the air interface resource information is reserved using the point-to-point transmission method by using pre-configured QoS information.

In this embodiment, matching multicast air interface resources can be reserved for the terminal through the above two manners.

Optionally, before reserving multicast air interface resources according to the multicast service information, the method further includes:

Send PDU session information to the core network function;

The multicast service information sent by the core network function is received, wherein the multicast service information is related to the PDU session information.

The above-mentioned PDU session information may include multicast related PDU session related information, wherein the multicast related PDU session may be a PDU session for receiving multicast service data. For example, the above-mentioned PDU session information may include at least one item of PDU session identifier, flow identifier, QoS-related information, and uplink channel information on the core network of the PDU session of the multicast service-related PDU session.

After the core network function receives the above-mentioned PDU session information, it can determine and send the above-mentioned multicast service information.

In this embodiment, the above steps can improve the efficiency of the terminal in acquiring the multicast air interface resources, and can also improve the switching efficiency of the multicast service.

Please refer to FIG. 4. FIG. 4 is a flowchart of a session establishment method provided by an embodiment of the present application. The method is applied to a core network function, as shown in FIG. 4, and includes the following steps:

Step 401 , establish a multicast-related PDU session, wherein the multicast-related protocol data unit PDU session is associated with the specified core network uplink channel resource information or specified flow identification information or specified service quality identification.

The above-mentioned multicast-related PDU session may be a PDU session that can be used to transmit multicast service data.

For the above-mentioned designated core network uplink channel resource information or designated flow identification information or designated service quality identification, reference may be made to the corresponding description of the embodiment shown in FIG. 3 , which will not be repeated here.

Optionally, the multicast-related PDU session is used for the source network side device to send a multicast service to the terminal, and after the multicast PDU session is established, the method further includes:

Receive the PDU session information sent by the target network side device;

Sending multicast service information to the target network side device, wherein the multicast service information is related to the PDU session information.

For the above-mentioned PDU session information and multicast service information, reference may be made to the corresponding description of the embodiment shown in FIG. 3 , which will not be repeated here.

In this embodiment, through the above steps, a PDU session for transmitting a multicast service can be established, thereby improving the sending effect of the multicast service.

Hereinafter, the method provided by the embodiment of the present application is described by taking the core network function as the source network side device to send the multicast service data using the multicast-related PDU session, the network side device being the gNB, and the core network function being the MB-SMF or MB-UPF. , as shown in Figure 5, including the following steps:

Step 1: Use the uplink channel resource information or QFI of the specific designated core network to indicate that there is a multicast service.

Since the multicast service only has downlink data but no uplink data, the core network function (such as SMF or UPF) uses the specified core network uplink channel resource information in the process of establishing a multicast-related PDU session. For example, CN UL Tunnel Info is all 0 or all 1. , or use a specified QoS flow identifier (QFI), such as a specified value or a value within a specified range, or use QoS information (ie, quality of service identifier) to represent multicast services, such as using dynamic 5QI configuration (dynamic-5QI configuration), where the specified 5QI value or the specified range of 5QI values are used to represent multicast services.

Step 2: The UE sends a measurement report to the source base station (source gNB).

Step 3: The Source gNB decides to perform the handover operation, selects the target base station (target gNB), and sends a handover request message to the target base station. For example, a Handover Request message can carry PDU session-related information, such as PDU Session ID (PDU Session ID), Flow Identification (QFI), QoS-related information, and uplink channel information on the core network of the PDU session.

Step 4: The target gNB determines the multicast service of the terminal based on the received uplink channel resource information of the designated core network or the designated QoS flow identification information, and can obtain the relevant information of the PDU session related to the multicast service.

Step 5: The target gNB can send a session update request to the core network function (for example, sent to SMF through AMF), and the request can carry PDU session related information, for example: including multicast service related PDU session related information.

Step 6: The core network function (such as SMF) obtains multicast service information based on the PDU session information, such as multicast service identifier, multicast service QoS information, etc., and sends the multicast service information to the target gNB (such as sent through AMF).

Step 7: In the case of performing steps 5 to 6, the target gNB reserves the air interface multicast resources based on the multicast service information. In the case of not performing steps 5 to 6, the target gNB uses the pre-configured scheme to pre-configure based on the judgment of the multicast service. Reserving air interface multicast resources, for example, using pre-configured QoS information to reserve air interface resource information using point-to-point transmission.

Step 8: The target gNB sends the multicast air interface resource information to the terminal through the Source gNB (or through the core network function and the source base station). Wherein, the multicast air interface resource information may include an indication indicating whether the UE can enter an idle state. For example, a redirect message is sent to the terminal instead of a handover command to indicate that it can enter the idle state, or no multicast service related PDU session related information is sent to the UE, or a specified multicast data transmission mode is included, wherein the specified multicast data The transmission mode may be a point-to-multipoint transmission mode, or the transmission mode may be indicated by the multicast air interface resource information of the point-to-multipoint transmission mode.

Step 9: The UE accesses the target gNB according to the received air interface resource information, and sends a handover confirmation message, such as a Handover Confirm (handover confirmation) message, to the target gNB, or the UE may enter the idle state based on the idle state indication without performing this step .

Step 10: It can be executed after step 7. The target gNB sends a session update message to the core network function (for example, sent to SMF through AMF). When steps 5 to 6 are executed, the message can carry the base station that established the multicast shared channel. The side downlink receives resource information, and does not send multicast service-related PDU session-related information. If steps 5 to 6 are not performed, the message carries PDU session-related information, including multicast service-related PDU session-related information.

Step 11: The core network function can interact with the target gNB to establish a multicast shared channel in the case of receiving the relevant information about the PDU session related to the multicast service, that is, send the relevant information of the multicast service to the target gNB, and the relevant information of the multicast service can be Including multicast service information, such as service identifiers of multicast services and QoS flow identifiers. Further, the target gNB can update the multicast air interface resource information based on the multicast service related information, and notify the UE of the updated multicast air interface resource information, and the target gNB can also send the multicast shared channel base station side downlink to the core network function. Receive resource information.
