However, the existing communication field protocol does not limit the internal structure of the terminal device supporting the MBMS, and the multicast data processing procedure in the terminal device is unclear.
To solve the foregoing problems, embodiments of the present invention provide a method and an apparatus for multicast data transmission. The following describes the multicast data transmission method and apparatus provided by the present invention in detail with reference to specific embodiments. In the following several embodiments, the same or similar concepts or processes may not be described in detail in some embodiments.
An aspect of an embodiment of the present invention provides a method for transmitting multicast data. Fig. 2 is a flowchart illustrating a multicast data processing method according to an embodiment of the present invention. The execution main body of the method is terminal equipment, and the terminal equipment comprises an application processing module, a data processing module during multicast and a receiving module. Each module may be software or hardware, which is not limited in this respect. The embodiment describes the architecture of the terminal device, and the channel and data management manner during multicast data reception. Illustratively, as shown in fig. 1 and fig. 2, the terminal device includes an application processing module, a multicast data processing module, and a receiving module.
Illustratively, the application processing module is used for displaying the multimedia service and the service content to the user in real time, receiving instructions input by the user, and the like. The receiving module includes a modem unit and an Internet Protocol Stack (IP Stack) unit. The modem unit may be configured to monitor service control information and service content transmitted on the multicast channel. When the modulation regulating module monitors the multicast channel, the IP Stack unit is used for buffering the monitored content. The modulation and demodulation unit and the IP Stack unit are packaged in an operating system of the terminal equipment. The multicast data processing module is respectively connected with the application processing module and the receiving module. The multicast data processing module can control and manage the modulation and demodulation unit through the operating system, and the application processing module needs to perform signaling interaction with the modulation and demodulation unit through the multicast data processing module. The IP Stack unit is visible to other modules outside the operating system, and can interact with the IP Stack unit through a preset interface. The IP Stack units of the multicast data processing module and the receiving module provide a uniform interface for the outside, and the application processing module is connected with the receiving module through the interface. The terminal equipment is divided into the application processing module, the multicast data processing module and the receiving module, so that the structure of the terminal equipment is layered, the terminal equipment is prevented from setting an interface on an operating system aiming at each application processing module, and the flexibility of the application processing module is ensured.
On the basis of the terminal device structure shown in fig. 1, the multicast data transmission method includes:
s201, the application processing module sends a multicast data receiving request message to the multicast data processing module.
For example, the application processing module may send a multicast data reception request message to the multicast data processing module when receiving a listening instruction/reception instruction input by a user, receiving a listening instruction/reception instruction sent by a server, or meeting other conditions.
S202, the multicast data processing module informs the receiving module to monitor the multicast channel indicated by the multicast data receiving request message.
Illustratively, after receiving the multicast data reception request message, the multicast data processing module notifies the receiving module to monitor the multicast channel indicated by the multicast data reception request message. Illustratively, the multicast data processing module sends a listen/receive indication message to the receiving module. When the receiving module receives the monitoring/receiving indication message, the receiving module starts monitoring the multicast channel, and the multicast channel monitored by the receiving module depends on the indication of the multicast channel monitoring request message. And the receiving module receives and caches the multicast data stream transmitted on the multicast channel in the IP Stack during monitoring. Illustratively, S201 and S202 implement multicast traffic channel management. The multicast service channel management is mainly realized by an application processing module, and the multicast data processing module realizes the forwarding function.
S203, the multicast data processing module obtains the multicast data stream indicated by the multicast data reception request message from the receiving module, pre-processes the multicast data stream, and sends the pre-processed multicast data stream to the receiving module.
Illustratively, the multicast data reception request message received by the multicast data processing module indicates a location of multicast data to be received in the multicast channel. The multicast data processing module can inform the application processing module to receive the multicast data to be received according to the position information, or the multicast data processing module can obtain the multicast data to be received from the receiving module according to the multicast data receiving request message, and the multicast data is sent to the IP Stack after being processed and then the application processing module obtains the multicast data.
The multicast data processing module may perform preprocessing on the multicast data, where the preprocessing may be Forward Error Correction (FEC) processing, Robust Header Compression (ROHC) processing, Secure Real-time Transport Protocol (SRTP) processing, Secure Real-time Transport Control Protocol (SRTCP) processing, or the like.
Illustratively, the multicast data processing module resends the preprocessed multicast data to the IP Stack of the receiving module. Illustratively, the multicast data processing module sends the preprocessed data to a specific location in the IP Stack specifically according to the multicast data reception request message. For example, the application processing module obtains the preprocessed multicast data from the receiving module, and specifically, the application processing module may determine the position of the preprocessed multicast data according to the multicast data receiving request message.
And S204, the application processing module acquires the preprocessed multicast data stream from the receiving module and processes the multicast data stream.
After receiving the multicast data, the application processing module may exemplarily process the multicast data according to the service class. Illustratively, S203 and S204 implement multicast data management. The multicast data management is mainly realized by an application processing module, and the multicast data processing module realizes the forwarding function.
The terminal device provided by this embodiment concentrates all functions such as multicast channel management and multicast data processing on the application processing module, the application processing module acquires MBMS related information in real time and processes multicast data, and decouples the service function of the MBMS from the multicast data processing module, thereby avoiding the problem of complex module structure that may be caused when the multicast data processing module has too many functions. Because the processing of the multicast data is performed by the application processing module instead of the multicast data processing module, the security of the multicast data is improved, and the requirement of data sensitive service can be met. Meanwhile, the application processing module combines the multicast channel monitoring and the multicast data receiving, thereby improving the processing efficiency.
The multicast data processing method provided by the embodiment of the invention is applied to terminal equipment comprising an application processing module, a data processing module during multicast and a receiving module, wherein the application processing module sends a multicast data receiving request message to the multicast data processing module; the multicast data processing module informs the receiving module to monitor the multicast channel indicated by the multicast data receiving request message; the multicast data processing module acquires the multicast data stream indicated by the multicast data receiving request message from the receiving module, preprocesses the multicast data stream, and sends the preprocessed multicast data stream to the receiving module; and the application processing module acquires the preprocessed multicast data stream from the receiving module and processes the multicast data stream. The multicast data processing method provided by the invention limits the multicast data processing method in the terminal equipment, and has higher stability and safety.
