Node (Master Node, MN), or unicast serving base station. As shown in Figure 1, the method includes the following steps:

Step 101: Receive negotiation information from a second network device.

In this embodiment, the aforementioned second network device may be a device that provides a Multimedia Broadcast Multicast Service (MBMS) for the terminal, such as a secondary node (Secondary Node, SN), or a multicast service base station. The aforementioned negotiation information may be sent and received through an interface (such as an Xn interface) between the first network device and the second network device.

The aforementioned negotiation information may include but is not limited to at least one of the following:

Information about the sending time of the target MBMS;

In at least one embodiment of the present disclosure, the negotiation process between the first and second network devices may be initiated by the first network device or the second network device, as detailed below.

method one

In a way, the negotiation process can be initiated by the first network device.

In this manner, before receiving the negotiation information from the second network device, the first network device may send negotiation request information to the second network device, and the negotiation request information requests the second network device to perform the negotiation process related to MBMS reception. In this way, with the aid of the negotiation request of the first network device, the first network device can obtain the target MBMS related information.

Optionally, the sending condition of the aforementioned negotiation request information may include any one of:

The first network device receives the interest status indication information about MBMS reception from the terminal; for example, if the UE1 indicates that the network node 1 is interested in MBMS 1 (or the MBMS of frequency point 1), then the network node 1 can cooperate with the MBMS to provide the MBMS 1 (Or MBMS at frequency 1) the network node 2 initiates the MBMS negotiation process;

The first network device receives the indication information from the terminal indicating that the terminal has established the configuration related to MBMS reception; for example, if the UE2 instructs the network node 1 to establish the configuration related to receiving MBMS 2 (or the MBMS of frequency point 2), the network The node 1 may initiate the MBMS negotiation process with the network node 2 that provides the MBMS 2 (or the MBMS of frequency point 2).

Way two

In the second way, the second network device can initiate the negotiation process.

In this manner, the first network device can directly receive the negotiation information from the second network device. The conditions for the second network device to send the negotiation information may include any one of:

The transmission time related information of the target MBMS has changed; for example, the network node 2 has provided the MBMS 1 transmission time related information 1 to the network node 1, but the transmission time related information 1 of the MBMS 1 has been changed and changed to the transmission time related information 2. Then, the network node 2 can initiate the MBMS negotiation process to provide the network node 1 with information 2 about the sending time of the MBMS 1;

The sending rate related information of the target MBMS has changed; for example, the network node 2 has provided the sending rate related information 1 of the MBMS 2 to the network node 1, but the sending rate related information 1 of the MBMS 2 has changed and changed to the sending rate related information 2. Then, the network node 2 can initiate the MBMS negotiation process to provide the network node 1 with information 2 about the transmission rate of MBMS 2.

In this way, it is convenient for the first network device to know the changed target MBMS related information in time, thereby avoiding the problem of data loss caused by the simultaneous unicast service and MBMS data capacity exceeding the total buffer capacity of the terminal, and improving the reliability of communication Sex.

In at least one embodiment of the present disclosure, after the terminal capability negotiation management related to MBMS reception is completed between the first network device and the second network device, the first network device may provide unicast services to the terminal in the following manner:

Send unicast service data (that is, no unicast service is provided for the terminal).

For example, within the scheduling time t1, the unicast serving base station judges that the total capacity of its unicast service data and the MBMS data received by UE1 will exceed the layer 2 buffer capacity of UE1, then within t1, the unicast serving base station may not be UE1 Provide unicast service to avoid data loss.

Method 2: When the total data capacity of the unicast service of the first network device and the MBMS data of the second network device exceeds the level 2 buffer capacity of the terminal within the scheduling time, the first network device adopts the reduced order during the scheduling time. It sends unicast service data to the terminal by means of broadcasting service rate.

For example, within the scheduling time t2, the unicast serving base station judges that the total capacity of its unicast service data and the MBMS data received by UE2 will exceed UE2's Layer 2 buffer capacity, then within t2, the unicast serving base station can use the lower The unicast service rate method provides unicast service for UE2 to avoid data loss.

It should be noted that the aforementioned reduction of the unicast service rate can be understood as reducing the total amount of data transmitted during the collision between the unicast service and the multicast service. The foregoing manner of reducing the unicast service rate may include but is not limited to at least one of the following:

Reduce the number of resource blocks (such as RB) available for unicast services;

Reduce the number of resource elements (such as RE) available for unicast services;

Use low-configuration modulation and coding strategies (such as MCS, such as adjusting from 16-QAM to QSPK).

Method 3: When the total data capacity of the unicast service of the first network device and the MBMS data of the second network device does not exceed the level 2 buffer capacity of the terminal within the scheduling time, the first network device is normally The terminal provides unicast service.

For example, within the scheduling time t3, the unicast serving base station determines that the total capacity of its unicast service data and the MBMS data received by UE3 does not exceed the capacity of UE3's Layer 2 buffer, then within t3, the unicast serving base station can normally be UE3 provides unicast services.
