The method, the device, the terminal and the network side equipment for acquiring the control signaling are described in detail through specific embodiments and application scenes thereof by combining the attached drawings.
Referring to fig. 2, fig. 2 is a flowchart of a method for receiving resource information, which is applied to a terminal and shown in fig. 2, and includes the following steps:
step 201, sending a measurement report for handover to a source network side device.
The measurement report may be a measurement report for handover of the terminal multi-source network side device to the target network side device. And the 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, and after the source network side device receives the measurement report, the source network side device may select a target network side device and send a Handover Request message (such as a Handover Request message) to the target network side device.
Further, the handover request message may further carry PDU Session related information, such as at least one of PDU Session identifier (PDU Session ID), flow identifier (QFI), quality of service (QoS) related information, PDU Session core network uplink channel information, and the like.
Step 202, receiving resource information, where the resource information is used to instruct a target network side device to transmit multicast air interface resources of 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 is not limited in this embodiment of the present application, for example: but may also be sent by a redirect message.
According to the embodiment of the application, after the measurement report is sent, the multicast air interface resource for transmitting the multicast service data by the target network side equipment can be rapidly acquired, so that the efficiency of acquiring the multicast air interface resource is improved, and further, the switching efficiency of the multicast service can be improved.
As an optional implementation manner, after the sending the measurement report for handover to the source network side device, the method further includes:
acquiring an idle state indication;
and entering an idle state or stopping sending a switching confirmation message to the target network side equipment according to the idle state indication.
The idle state indication may be obtained based on the resource information, for example: the resource information explicitly or implicitly indicates the idle state indication.
The above idle state indication may be used to instruct the terminal to enter an idle state, so that after the terminal obtains the indication, the terminal may enter the idle state or stop sending a handover confirmation message to the target network side device, so as to receive the multicast service data in the idle state, or receive the multicast service data in the case that the handover is not completed.
In addition, if the terminal is indicated 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 acquiring the idle state indication includes at least one of:
receiving a redirection message;
receiving transmission mode information of a target multicast service;
the resource information does not include PDU session information.
The redirection message may be sent by the source network side device, where the redirection message may carry the resource information. The target multicast service transmission mode information may be included in the resource information, and the target multicast service transmission mode information may be a point-to-multipoint transmission mode, which is not limited, for example: may be multicast traffic transport information predefined in the protocol.
Further, when at least one of the received redirection message, the received target multicast service transmission mode information, and the resource information not including PDU session information is satisfied, it may be determined that the terminal is instructed to enter a spatial state.
In some embodiments, the idle state indication has two indication states, one indicates that the idle state is entered, and the other indicates that the idle state is not entered. For example: the resource information includes PDU session information, indicating not to enter an idle state, or the resource information does not include target multicast service transmission mode information, indicating not to enter an idle state, or the like.
Optionally, after the terminal enters the idle state, the method further includes:
and receiving the multicast service data sent by the target network side equipment at the multicast air interface resource.
In the embodiment, the terminal can receive the multicast service data sent by the target network side device in an idle state. For example: the target network side device may send the multicast service data to the terminal through the multicast shared channel or the dedicated channel, which is not limited to this, for example: multicast service data sent by the target network side device can also be received in an idle state by other modes defined by a protocol.
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 the PDU session switching is not required to be performed, and the power consumption of the terminal can be saved.
In the embodiment of the application, a measurement report for switching is sent to source network side equipment; and receiving resource information, wherein the resource information is used for indicating a multicast air interface resource for transmitting multicast service data by the target network side equipment. Therefore, after the terminal sends the measurement report to the source network side equipment, the multicast air interface resource of the target network side equipment for transmitting the multicast service data can be obtained, and the efficiency of obtaining the multicast air interface resource is improved.
Referring to fig. 3, fig. 3 is a flowchart of a method for sending resource information, which is provided in an embodiment of the present application, and is applied to a target network side device, as shown in fig. 3, and includes the following steps:

In this embodiment, the efficiency of the terminal for acquiring the multicast air interface resource can be improved through the steps described above.
As an optional implementation manner, the reserving multicast air interface resources according to the situation that the terminal has multicast service includes:
and reserving multicast air interface resources according to PDU session information sent by source network side equipment, wherein the PDU session information is used for indicating that the terminal has multicast service.
The PDU session information may be used to indicate that the terminal has a multicast service, and the PDU session information is implicitly or explicitly used to indicate that the terminal has a multicast service.
For example: the reserving multicast air interface resources according to the PDU session information sent by the source network side device includes:
And reserving multicast air interface resources according to the specified core network uplink channel resource information or the specified stream identification information or the specified quality of service (QI) included in the PDU session information.
The specified core network uplink channel resource information or the specified stream identification information or the specified service quality identification included in the PDU session information can determine that the terminal has multicast service, and further reserve multicast air interface resources.
The specified qos identifier may be a specified 5G qos identifier (5G QoS Identifier,5QI) defined in a specified 5G system, and of course, may be applied to 6G, and the specified qos identifier may be a specified qos identifier defined in a specified 6G system.
In this embodiment, since the multicast service has only downlink data and no uplink data, the core network function (such as SMF or UPF) uses the specified core network uplink channel resource information (CN UL Tunnel Info) to be all 0 or all 1, or uses the specified QoS flow identifier or indication QI to represent the multicast service in the process of establishing the multicast-related PDU session.
The specific core network uplink channel resource information or the specific flow identification information or the specific service quality identification may be protocol convention, or preconfigured, etc., which are not limited thereto, and the specific core network uplink channel resource information or the specific flow identification information or the specific service quality identification may be understood as specific core network uplink channel resource information or specific flow identification information or specific service quality identification.
In the above embodiment, since the multicast air interface resource is 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 resource, so as to save the resource overhead.
As an alternative embodiment, the method further comprises:
and providing an idle state indication to the terminal.
Optionally, the providing the idle state indication to the terminal includes at least one of:
sending a redirection message;
transmitting the transmission mode information of the target multicast service;
the resource information does not include at least one of PDU session information.
The above idle state indication may refer to the corresponding description of the embodiment shown in fig. 2, which is not limited herein.
As an optional implementation manner, after the sending resource information to the terminal, the method further includes:
and sending the multicast service data to the terminal according to the multicast air interface resource.
The foregoing description of the embodiment shown in fig. 2 may be referred to for sending multicast service data, which is not limited herein.
As an optional implementation manner, the reserving multicast air interface resource includes:
reserving multicast air interface resources according to multicast service information; or alternatively
And reserving multicast air interface resources according to the pre-configuration information.
The multi-play service information may be sent by a core network function, which is not limited to this, for example: or may be sent by the source network side device.
The multicast service information may include at least one of multicast service identification, multicast service QoS information, and the like.
The reserving multicast air interface resources according to the multicast service information may be reserving multicast air interface resources matched with the multicast service.
The reserving the multicast air interface resource according to the pre-configuration information may be reserving the air interface multicast resource by using a pre-configuration scheme based on the judgment that the terminal has the multicast service when the multicast service information is not acquired. For example: such as reserving air interface resource information using point-to-point transmission with pre-configured QoS information.
In this embodiment, the reservation of the matched multicast air interface resource for the terminal can be achieved in the two modes.
Optionally, before the reserving the multicast air interface resource according to the multicast service information, the method further includes:

For example: the PDU session information may include at least one of PDU session identification, flow identification, qoS related information, PDU session core network uplink channel information, and the like of the multicast service related PDU session.
After the core network function receives the PDU session information, the multicast service information may be determined and transmitted.
In this embodiment, the efficiency of the terminal for acquiring the multicast air interface resources can be improved through the steps, and the switching efficiency of the multicast service can also be improved.
Referring to fig. 4, fig. 4 is a flowchart of a session establishment method according to an embodiment of the present application, where the method is applied to a core network function, as shown in fig. 4, and includes the following steps:
step 401, establishing a multicast-related PDU session, wherein the multicast-related protocol data unit PDU session association designates uplink channel resource information on a core network or designates stream identification information or designates a quality of service identification.
The multicast-related PDU session may be a PDU session that can be used to transmit multicast service data.
The above-mentioned uplink channel resource information on the designated core network or the designated flow identification information or the designated service quality identification may refer to the corresponding description of the embodiment shown in fig. 3, and will not be described herein.
Optionally, the multicast-related PDU session is used for the source network side device to send the multicast service to the terminal, and after the multicast PDU session is established, the method further includes:
receiving PDU session information sent by target network side equipment;
and sending multicast service information to the target network side equipment, wherein the multicast service information is related to the PDU session information.
The PDU session information and the multicast service information may be referred to the corresponding descriptions of the embodiment shown in fig. 3, which are not repeated herein.
In this embodiment, the PDU session for transmitting the multicast service may be established through the above steps, so as to improve the sending effect of the multicast service.
The method provided by the embodiment of the present application is illustrated by using a core network function to send multicast service data through a source network side device using a multicast-related PDU session, where the network side device is a gNB, and the core network function is an MB-SMF or an MB-UPF, as shown in fig. 5, and includes the following steps:
Step 1: the presence of multicast traffic is indicated using specific designated core network uplink channel resource information or QFI.
Since multicast traffic has only downstream data and no upstream data, the core network function (e.g., SMF or UPF) uses the assigned core network upstream channel resource information, e.g., CN UL Tunnel Info, to be all 0 or all 1, or uses the assigned QoS Flow Indicator (QFI), e.g., a certain assigned value or a value within a certain assigned range, or uses the QoS information (i.e., quality of service indicator) to indicate multicast traffic, e.g., using a dynamic 5QI configuration (dynamic-5 QI configuration), where there is multicast traffic using the assigned 5QI value or the assigned range of 5QI value.
Step 2: the UE sends a measurement report to a source base station (source gNB).
Step 3: the Source gNB decides to perform a handover operation, selects a target base station (target gNB), and sends a handover request message to the target base station. Such as a Handover Request message, which may carry PDU Session related information, such as PDU Session identification (PDU Session ID), flow identification (QFI), qoS related information, PDU Session core network uplink channel information, etc.
Step 4: the target gNB judges that the terminal has the multicast service based on the received specified uplink channel resource information or the specified QoS flow identification information, and can obtain the related PDU session related information of the multicast service.
Step 5: the target gNB may send a session update request (e.g., sent to the SMF via the AMF) to the core network function, which may carry PDU session related information, for example: including multicast service related PDU session related information.
Step 6: the core network function (e.g., SMF) obtains multicast service information, such as multicast service identification, multicast service QoS information, etc., based on the PDU session information and sends the multicast service information (e.g., via AMF) to the target gNB.
Step 7: under the condition of executing the steps 5-6, the target gNB reserves the air interface multicast resources based on the multicast service information, and under the condition of not executing the steps 5-6, the target gNB reserves the air interface multicast resources based on the judgment of the multicast service, such as the use of the point-to-point transmission mode by adopting the pre-configured QoS information.
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 may enter an idle state. For example, a redirection message is sent to the terminal instead of a handover command to indicate that the idle state can be entered, or no multicast service related PDU session related information is sent to the UE, or a designated multicast data transmission mode is included, where the designated multicast data transmission mode may be a point-to-multipoint transmission mode, or the transmission mode may be indicated by multicast air interface resource information of the point-to-multipoint transmission mode.
Step 9: the UE accesses to the target gNB according to the received air interface resource information, and sends a Handover Confirm message, such as a Handover Confirm message, to the target gNB, or the UE may enter an idle state based on the idle state indication without performing this step.
Step 10: the method may be performed after step 7, where the target gNB sends a session update message (e.g. sent to the SMF through the AMF) to the core network function, and where steps 5 to 6 are performed, the message may carry base station side downlink reception resource information for establishing a multicast shared channel, and no multicast service related PDU session related information is sent, and where 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 may interactively establish a multicast shared channel with the target gNB in case of receiving multicast service related PDU session related information, i.e. send the multicast service related information to the target gNB, where the multicast service related information may include multicast service information, for example: service identification, qoS flow identification of multicast service. Furthermore, the target gNB may 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 may also send the multicast shared channel base station side downlink receiving resource information to the core network function.
