Referring to fig. 2, fig. 2 provides a method for switching a transmission link, where the transmission link in the embodiment of the present application has two transmission links, namely a first link and a second link, and for convenience of description, the first link is named leg1, and the second link is named leg 2; wherein the first link leg1 is in the first transmission mode, and the second link leg2 is in the second transmission mode. The first transmission mode may be different from the second transmission mode, for example, the first transmission mode is a unicast mode (PTP transmission mode) and the second transmission mode is a multicast mode (PTM transmission mode), but the reverse is also possible. The method may be implemented in a communication system as shown in fig. 1, and the method as shown in fig. 2 may be performed by a terminal in the communication system as shown in fig. 1, and the method as shown in fig. 2 includes the following steps:
step S201, the terminal receives an MBS (Multicast/Broadcast Service) data packet on a first link leg 1;
in an alternative scheme, the leg1 may be a unicast link, but in practical applications, the leg1 may also be a multicast link.
And step S202, when the terminal determines that the first preset condition is met, the terminal switches the leg1 to a second link leg2 to receive the MBS data packet.
In an optional scheme, the determining, by the terminal, that the first preset condition is met may specifically include:
if the identifier of the terminal receiving the MBS data packet at the leg2 is the same as the identifier of the MBS data packet already received by the leg1, determining that a first preset condition is met; the identifier of the terminal receiving the MBS data packet at the leg2 is the same as the identifier of the MBS data packet already received by the leg1, and for the RLC AM mode, the hole (gap) indicating that the terminal receives the data packet during the link handover is full, i.e., no received data packet is lost.
The identifier of the data packet may be a data packet ID or a sequence number sn (sequence number) of a certain protocol layer, and the sequence number of the data packet may be a data packet sequence number of an SDAP layer, a PDCP layer, or an RLC layer.
Or if the terminal includes a timer1, the timer is used to time the transmission time of the leg1, and if the timer1 is out of time, it is determined that the first preset condition is met. The timer1 is started when the terminal prepares or starts to receive data in the leg2 or receives the first data packet from the leg2, or after receiving the indication of the link switch from the network side.
In an alternative, the timer1 may be a preconfigured timer, but in practical applications, the timer may also be a timer configured on the network side, for example, the timer may be configured through a system message or RRC signaling. Configuring the timer through system messages or RRC signaling can improve the flexibility of the timer.
According to the technical scheme provided by the application, the MBS data packet is received at the leg1 of the first link; and when the terminal determines that the first preset condition is met, the terminal switches the leg1 to the second link leg2 to receive the MBS data packet. Therefore, the soft switching of the transmission mode can be executed on the MBS data packet, the network time delay is reduced, the transmission reliability of the data packet is improved, and the network performance and the user experience degree are improved.
In an optional scheme, before the terminal switches the leg1 to the second link leg2 to receive the MBS data packet, the method may further include:
the terminal sends a notification message to the network side, and the communication message may include: an indication that a first preset condition is met.
The notification message may be an existing message in the system, and may be, for example, an RRC message, a MAC CE, a PDCP/SDAP/RLC control PDU, or the like. Of course, in practical application, the method can also be realized by the message configured newly. The application does not limit the specific expression form of the notification message, and only needs that the notification message carries an indication meeting the first preset condition. The indication may be a special character string or a predetermined specific symbol, etc.
In an optional aspect, the method may further include:
the terminal receives a notification response issued by the network side, and the notification response may further include: and deactivating the leg1 or releasing the leg1, and the terminal performs deactivation or release operation on the leg1 according to the notification response.
The notification response includes: RRC message, MAC CE, or DCI.
If the notification response contains release leg1, then the RRC message is preferred because of the poor flexibility for RRC messages relative to MAC CE; if leg1 is deactivated, the MAC CE may be prioritized. The deactivation of a link means that the base station no longer transmits data on the link, and the terminal no longer receives data on the link, but the configuration information of the link is reserved.
The technical scheme is to avoid that the terminal occupies network resources of the leg1 for a long time, and occupies certain network resources for deactivating the leg1, but has the advantages that the leg1 can be reactivated through an activating instruction, the flexibility is high, the leg1 network resources do not need to be reconfigured, for the releasing operation, the network resources are not occupied, namely other terminals can use the network resources of the leg1, the defect is inflexibility, and if the leg2 needs to be switched, a network side needs to reconfigure a new link for the terminal.
In an optional aspect, the method may further include:
when the terminal times out at time1, the terminal deactivates leg1 or releases leg 1.

A protocol architecture scenario provided in the embodiment of the present application is shown in fig. 3, where this embodiment may be executed in the communication system shown in fig. 1, and the method shown in fig. 4 may specifically include:
step S400, the base station sends MBS data packet to the terminal in PTP leg, the base station sends MBS data packet in PTM leg,
step S401, when the PTM leg receives the 15 th MBS data packet, the terminal determines that the preset condition is met, stops receiving the MBS data packet from the PTP leg and sends a notification message (MAC CE) to the base station;
step S402, after receiving the notification message, the base station deactivates or releases the PTP leg.
According to the technical scheme provided by the application, an MBS data packet is received at a PTP leg; and when the terminal determines that the first preset condition is met, the terminal switches the PTP leg into the PTM leg to receive the MBS data packet. Therefore, the soft switching of the transmission mode can be executed on the MBS data packet, the network time delay is reduced, the transmission reliability of the data packet is improved, and the network performance and the user experience degree are improved.

PTP legs refer to links for transmitting data in a unicast manner, and each leg corresponds to one or more protocol entities of different protocol layers, such as one or more of a physical layer protocol entity, MAC, RLC, PDCP, and SDAP. A protocol architecture scenario provided in the embodiment of the present application is shown in fig. 5, where this embodiment may be executed in the communication system shown in fig. 1, and the method shown in fig. 6 may specifically include:
step S600, the base station sends MBS data packet to the terminal in PTP leg, the base station sends MBS data packet in PTM leg,
step S601, the terminal starts a timer1 when a PTM leg receives an MBS data packet, and when the timer1 times out, the terminal determines that a preset condition is met, stops receiving the MBS data packet from the PTP leg and sends a notification message to a base station;
step S602, after receiving the notification message, the base station deactivates or releases the PTP leg.
According to the technical scheme provided by the application, an MBS data packet is received at a PTP leg; when the terminal determines that the timer1 is over time and meets a first preset condition, the terminal switches the PTP leg into the PTM leg to receive the MBS data packet. Therefore, the soft switching of the transmission mode can be executed on the MBS data packet, the network time delay is reduced, the transmission reliability of the data packet is improved, and the network performance and the user experience degree are improved.
