Detailed Description

In the embodiment of the application, the term "and/or" describes the association relationship of the association objects, which means that three relationships may exist, for example, a and/or B may be represented: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in the embodiments of the present application means two or more, and other adjectives are similar thereto.

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The embodiment of the application provides a transmission processing method and device for multicast service. The method and the device are based on the same application, 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.

As shown in fig. 1, a method for processing transmission of a multicast service according to an embodiment of the present application includes:

step 101, under the condition that a terminal is in an inactive state and the transmission requirement of multicast service exists, the terminal determines configuration information of Small Data Transmission (SDT);

and 102, the terminal indicates the multicast service related information to the network side equipment according to the configuration information.

Here, for a terminal, the transmission requirement of a multicast service is understood to mean a multicast service that is of interest to receive or is being received. Whereas small data transfer (Small Data Transmission, SDT) allows the terminal to send data to the network side device in the inactive state, avoiding the extra power consumption and signaling overhead of sending data into the connected state, etc. Therefore, if the terminal in the inactive state is interested in receiving or receiving the multicast service, the terminal indicates the multicast service related information to the network side equipment according to the configuration information by determining the configuration information of small data transmission, and the terminal transmits the multicast service related information by triggering the SDT so that the network side equipment can send the corresponding service in a corresponding mode supporting the inactive state to realize the multicast service transmission in the inactive state and avoid that the terminal can only receive the multicast service in the connected state.

It should also be appreciated that, when the terminal is in an Inactive state (rrc_inactive), the multicast service it is receiving may not be transmitted in some frequency points or cells, so that after the cell reselection, the method of the embodiment of the present application may also be applied by the terminal, so as to ensure that the network side device knows the multicast service related information of the terminal.

The configuration information of the small data transmission may be predefined or configured by the network side device.

Optionally, in this embodiment, the configuration information includes: small data transmission resource information and a first threshold.

Here, the small data transmission resource information is used to indicate a resource used for small data transmission, and specifically includes time domain and/or frequency domain information of the resource. And the first threshold is used for representing a data volume threshold of the small data transmission resource and limiting the size of the data volume transmitted on the small data transmission resource.

Optionally, step 101 includes:

Here, the first uplink resource is a resource indicated by configuration information of the small data transmission, such as a PUSCH resource configured for the small data, or may be a resource other than a resource configured for the non-small data (such as a RACH resource that needs to be used due to random access initiated by needing to return to a connected state). The terminal in the inactive state can select a first uplink resource, trigger small data transmission, and indicate multicast service related information through the first uplink resource.

The multicast service related information is carried, for example, in a radio resource control (Radio Resource Control, RRC) Resume Request (Resume Request). Of course, besides RRC Resume Request, it may be carried in other messages from the terminal to the network side device.

In addition, the mapping relation between the first uplink resource and the multicast service related information can be configured in advance, so that the multicast service related information can be implicitly indicated through the selected first uplink resource without carrying out explicit bearing by a certain message.

Optionally, in this embodiment, the multicast service related information includes at least one of:

multicast service transmission information;

multicast service identification.

Wherein, the multicast service transmission information can represent that there is a transmission requirement of the multicast service, that is, the multicast service of interest or being received; or, whether there is a transmission requirement for the multicast service, i.e. whether there is a multicast service of interest or being received. For example, the RRC Resume Request carries 1bit multicast service transmission information, and if the multicast service transmission information is "0", there is no transmission requirement of the multicast service; if the multicast service transmission information is "1", there is a transmission requirement of the multicast service. Of course, if the terminal is in the flow of small data transmission, i.e. the terminal has already transmitted RRC Resume Request, it should not transmit again, but the multicast service transmission information is carried by other messages such as UE assistance information (UE assureinformation).

The multicast service identifier may be a temporary mobile group identifier (Temporary Mobile Group Identity, TMGI) of the multicast service, where the TMGI includes information such as a public land mobile network (Public Land Mobile Network, PLMN), a multicast service ID, and the like. For example, the terminal selects the first uplink resource, and uses MBS Interest Indication message or UE Assistance Information to carry { TMGI of multicast service a, TMGI of multicast service B }, where multicast service a and multicast service B are multicast services that are of interest to or are being received by the terminal. Of course, the multicast service identifier may also be carried in other messages from the terminal to the network side device, which are not listed here.

It should be noted that, considering that the first uplink resource is used for the inactive state, and a data threshold exists, in this embodiment, optionally, the terminal indicates, to the network side device, the multicast service related information through the first uplink resource, including:

That is, the terminal can determine the content of the multicast service related information indicated to the network side device according to the data threshold of the first uplink resource. Under the condition that the first threshold value does not allow the multicast service identification to be sent, namely the data threshold of the first uplink resource does not allow the multicast service identification to be sent, the terminal only indicates the multicast service transmission information through the first uplink resource; and when the first threshold value allows sending the multicast service identifier, that is, the data threshold of the first uplink resource allows sending the multicast service identifier, the terminal sends at least part of the multicast service identifier through the first uplink resource, and the first uplink resource can also indicate multicast service transmission information.

If the data threshold of the first uplink resource does not allow all multicast service identifiers to be sent, the first uplink resource only sends part of the multicast service identifiers.

For example, the terminal receives a data amount threshold of the configured small data transmission from the network side device, i.e. the first threshold is X bytes. And when the data quantity required to be transmitted by the terminal is smaller than X bytes, initiating a small data transmission flow. In some cases, multicast service related information to be transmitted (e.g., due to the terminal having to transmit multiple service related information) may be large, resulting in a larger amount of data to be transmitted than X bytes. In this case, the terminal selects a part of the multicast service to transmit the multicast service identifier of the part of the multicast service, so as to ensure that the data volume required to be transmitted is not greater than X bytes.

Further optionally, in this embodiment, after step 102, the method further includes:

Here, the terminal indicates the multicast service transmission information to the network side device, and triggers the small data transmission process, but in order to ensure the effective transmission of the multicast service identifier, the terminal further sends the data volume of the multicast service identifier to be transmitted to the network side device, so as to request the network side device for scheduling applicable resources. After the network side equipment acquires the data volume of the multicast service identifier to be transmitted, allocating resources for the terminal based on the data volume of the multicast service identifier to be transmitted, determining uplink scheduling information and transmitting the uplink scheduling information to the terminal. The uplink scheduling information is configuration information of resources allocated to the terminal by the network side equipment.

The data volume of the multicast service identifier to be transmitted can be sent through a state buffer report (Buffer Status Report, BSR), the BSR is configured to be specially used for sending the data volume of the multicast service identifier to be transmitted, and the BSR is sent through a MAC CE mode.

Then, optionally, in this embodiment, after the terminal receives the uplink scheduling information sent by the network side device, the method further includes:

After receiving the uplink scheduling information of the network side equipment, the terminal determines a second uplink resource according to the uplink scheduling information, and then determines and transmits at least part of the packet broadcast service identifier according to the second uplink resource. At this time, the size of the second uplink resource allows the amount of data to be transmitted at least equal to the amount of data of the at least part of multicast service identifier.

For example, if the terminal in the inactive state is interested in receiving or receiving the multicast service, the terminal triggers a small data transmission process, indicates "interested in or receiving the multicast service" by carrying 1bit in RRC ResumeRequest message or UE auxiliary information message, and meanwhile, the terminal reports BSR information to the network side device, and informs the network side device of the amount of data of the multicast service identifier to be transmitted (the content size of the "service ID of the multicast service" that is desired to be reported), such as how many bits altogether. After receiving the BSR, the network side device knows the multicast service ID and the size thereof that the UE will send to the network, and if the UE is agreed to report the information, it sends uplink scheduling information to the UE, where the uplink scheduling information is transmitted in the PDCCH, and the uplink scheduling information may indicate which uplink resources the UE specifically uses to send the "service identifier of the multicast service" to the network side device. Then, the UE determines how many multicast service IDs to report (if the uplink resources allocated by the network side device are larger) based on the uplink resources (uplink resources allocated by the network side device) corresponding to the uplink scheduling information, and reports a part of the multicast service IDs to the network side device first if the uplink resources allocated by the network side device are smaller), and puts the multicast service ID information in an RRC message (such as UE auxiliary information) to report to the network side device.

Of course, if the terminal in the small data transmission flow finds that there is a transmission requirement of the multicast service, the data volume of the multicast service identifier to be transmitted may also be sent to the network side device; receiving uplink scheduling information determined by the network side equipment based on the data volume of the multicast service identifier to be transmitted; determining a third uplink resource according to the uplink scheduling information; and determining and transmitting at least part of the packet broadcast service identification according to the third uplink resource.

For example, the terminal in the inactive state is already in the small data transmission flow, that is, the terminal has sent RRC Resume Request message to the network, if the terminal is currently interested in a certain multicast service and the terminal is still in the small data transmission flow at this time, the terminal may report BSR information to the network side device, and notify the network side device UE of the amount of data of the multicast service identifier to be transmitted (the content size of the "service ID of the multicast service" that is desired to be reported), such as how many bits altogether. After receiving the BSR, the network side device sends uplink scheduling information to the UE if the UE is agreed to report the information, where the uplink scheduling information is transmitted in the PDCCH, and the uplink scheduling information may indicate which uplink resources are specifically used by the UE to send a "service identifier of a multicast service" to the network side device. Then, the UE determines how many multicast service IDs to report (if the uplink resources allocated by the network side device are larger) based on the uplink resources (uplink resources allocated by the network side device) corresponding to the uplink scheduling information, and reports a part of the multicast service IDs to the network side device first if the uplink resources allocated by the network side device are smaller), and puts the multicast service ID information in an RRC message (such as UE auxiliary information) to report to the network side device.

In summary, when the terminal is in an inactive state, the multicast service it is receiving may not be transmitted in some frequency points or cells; or the terminal does not provide the multicast service which is interested in the current cell and is received in the cell, and the terminal indicates the related information of the multicast service to the network side equipment to inform the network side equipment that the terminal is interested in or is receiving the related multicast service, so that the terminal can continuously receive the multicast service and has the advantages of lower time delay, lower power consumption, lower network load and the like.

As shown in fig. 2, the embodiment of the present application further provides a method for processing transmission of a multicast service, including:

step 201, when a terminal is in an inactive state and there is a transmission requirement of a multicast service, a network side device obtains multicast service related information indicated by configuration information of small data transmission of the terminal.

In this way, the network side device obtains the multicast service related information indicated by the configuration information of the small data transmission under the condition that the transmission requirement of the multicast service exists by the terminal in the inactive state, and can send the corresponding service in a corresponding mode supporting the reception in the inactive state later, thereby realizing the transmission of the multicast service in the inactive state and avoiding that the terminal can only receive the multicast service in the connection state.

If the configuration information of the small data transmission is configured by the network side device, the network side device may also send the configuration information to the terminal before step 201.
