Problems solved by technology

The switching between the multicast broadcast mode and the unicast mode lacks flexibility. In addition, even if a service state more suitable for the unicast mode appears in the multicast broadcast mode, the base station cannot switch to the unicast mode, which further leads to a loss of wireless resources. Decrease in Scheduling Utilization

Embodiment 1

[0078] According to a specific example of the method embodiment of the present invention, Figure 4 The method of the embodiment may also include the following operations to obtain the QoS of the eMBMS service:

[0079] The base station receives the notification message containing the QoS of the eMBMS service pushed by the core network element; or the base station queries the core network element for the QoS of the eMBMS service, and obtains the QoS of the eMBMS service according to the query result message returned by the core network element.

[0080] See Figure 5 As shown, this figure shows a schematic flowchart of an embodiment of a method for resource scheduling of a multicast broadcast service in a long-term evolution system provided by the present invention. versus Figure 4 Compared with the illustrated embodiment, in response to the number of users not meeting the second broadcast threshold condition, the method further includes: 501, the base station recognizes whether th...

Abstract

The invention discloses a resource scheduling method, device and base station for long-term evolution system multicast broadcasting service. The method comprises the steps that the base station identifies whether the number of users meets the predetermined first broadcasting threshold condition in a predetermined cycle or in real time according to the number of the users subscribing the eMBMS service in a multicast broadcasting single frequency network (MBSFN) region; the number, meeting the first broadcasting threshold value, of the users is responded, the base station distributes multicast broadcasting subframes BMS to serve as service subframes, and a control channel comprised by the BMS contains instruction information of service data received by a user terminal through a data channel; the number, which does not meet the first broadcasting threshold value, of the users is responded, unicast subframes are distributed to serve as the service subframes, and the service data are borne; the base station inserts the service subframes in a downlink data frame sequence, and sends the data frame sequence to the user terminal in the MBSFN region. According to the technical scheme, scheduling modes of the base station can be flexibly switched between the multicast broadcasting mode and the unicast broadcasting mode, and the flexibility and the resource utilization rate of eMBMS service resource scheduling are improved.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and base station for resource scheduling of a long-term evolution system multicast broadcast service. Background technique [0002] In recent years, with the rapid development of mobile Internet application technologies, users' demands for high-bandwidth multimedia services have also increased. For example, more and more users have adopted video broadcasting and TV advertising services. As an effective means of carrying high-bandwidth multimedia services, the multicast broadcast method is increasingly being applied to various multicast broadcast services. [0003] Long Term Evolution (Long Term Evolution, LTE) is a new generation wireless communication system launched by 3GPP. The LTE system defines the evolved Multicast Broadcast Multimedia Service (eMBMS) solution, and introduces the Multicast Broadcast Single Frequency Network (MBSFN) transmission metho...
