Node (MasterNode, 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 above-mentioned second network device may be a device that provides a multimedia broadcast multicast service (Multimedia Broadcast Multicast Service, MBMS) for the terminal, such as a secondary node (Secondary Node, SN), or a multicast service base station. The above 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 above negotiation information may include, but is not limited to, at least one of the following:

Information about the sending time of the target MBMS;

Information about the transmission rate of the target MBMS.

It should be noted that, the above target MBMS can be selected as one MBMS, or multiple MBMSs. The multiple MBMSs may be MBMSs of a certain frequency. The above-mentioned target MBMS may be the MBMS that the terminal is interested in, or may be the MBMS in which the time-related information and/or the transmission rate-related information is changed.

Optionally, the information related to the sending time of the target MBMS may include, but is not limited to, at least one of the following:

The sending time period of the target MBMS; for example, MBMS 1 sends every 10ms; and MBMS 2 sends every 20ms;

Data loss problem, improve the reliability of communication.

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

method one

In one way, the negotiation process may be initiated by the first network device.

In this manner, before receiving negotiation information from the second network device, the first network device may send negotiation request information to the second network device, the negotiation request information requesting the second network device to perform a negotiation process related to MBMS reception. In this way, with the help of the negotiation request of the first network device, the first network device can be made to obtain the relevant information of the target MBMS.

Optionally, the sending conditions of the above negotiation request information may include any one of:

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

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

Method 2

In the second manner, the negotiation process may be initiated by the second network device.

In this manner, the first network device can directly receive 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 sending time-related information of the target MBMS has changed; for example, the network node 2 has provided the network node 1 with the sending time-related information 1 of the MBMS 1, but the sending time-related information 1 of the MBMS 1 has changed and is changed to the sending time-related information 2, then, the network node 2 can initiate an MBMS negotiation process to provide the network node 1 with the sending time-related information 2 of the MBMS 1;

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

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

In at least one embodiment of the present invention, 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 can provide the terminal with a unicast service in the following manner:

Mode 1: 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 layer 2 buffer capacity of the terminal within the scheduling time, the first network device does not send data to the terminal within the scheduling time. Send unicast service data (ie, do not provide unicast service for the terminal).

For example, within the scheduling time t1, the unicast serving base station determines 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. Unicast service is provided to avoid data loss.

Mode 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 Layer 2 buffer capacity of the terminal within the scheduling time, the first network device uses a reduced unicast service within the scheduling time. The unicast service data is sent to the terminal by means of the broadcast service rate.

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

It should be noted that the above reduction of the unicast service rate can be understood as reducing the total amount of data transmitted by the unicast service within the collision time with the multicast service. The above method for 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 RBs) available for unicast services;

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

Use a low profile modulation coding strategy (eg MCS, eg from 16-QAM to QSPK).

Mode 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 layer 2 cache capacity of the terminal within the scheduling time, the first network device will normally be in the scheduling time. 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 layer 2 buffer capacity of UE3, then within t3, the unicast serving base station can normally be UE3 provides unicast services.
