Problems solved by technology

However, the above method cannot be applied when the base station does not support node synchronization
The base stations of some manufacturers do not support node synchronization, so it is impossible to realize the synchronous transmission of MBMS data based on node synchronization

Abstract

The invention provides a method of realizing multimedia broadcasting and group broadcasting operation transmission in-phase, the method includes: data is marked with time when generating multimedia broadcasting and group broadcasting operation data, and deciding the transmission time of empty port according to the time mark; calculating the data transmission frame number of areola based on the transmission time of empty port. The implement of the invention can realize the synchronization transmission of MBMS operation in an areola on condition that base station does not support node synchronization.

Description

A method for synchronous transmission of multimedia broadcast and multicast service data technical field The invention relates to the field of multimedia broadcast and multicast service (MBMS), in particular to a method for realizing synchronous transmission of multimedia broadcast and multicast service data. Background technique In a traditional mobile network, CellBroadcastService allows low-bit-rate data to be sent to all users through a cell-shared broadcast channel, and is a message service. Now, people's demand for mobile communication is no longer satisfied with telephone and messaging services. With the rapid development of the Internet, a large number of multimedia services have emerged. In order to effectively utilize mobile network resources, the WCDMA global standardization organization 3GPP (3rd Generation Partnership Project) proposed a multimedia broadcast and multicast service (MBMS: Multimedia Broadcast and Multicast Service), which provides a data source ...
