Abstract

The invention provides a data encapsulation device and a method thereof used for multimedia broadcast/multicast service data. The data encapsulation device comprises a classification and restriction module used for classifying multimedia broadcast/multicast service data into at least one data type according to service application and restricting the data structure of the multimedia broadcast/multicast service data according to data types; an identification and description module used for identifying different multimedia broadcast/multicast service data according to data volume identifications and describing the multimedia broadcast/multicast service data according to the restricted data structure; and a data encapsulation module used for encapsulating the described multimedia broadcast/multicast service data in different segments and mapping the encapsulated multimedia broadcast/multicast service data to a data unit of a transmission layer for transmission. The data encapsulation device can meet the requirements for transmitting various service data and supporting various complex service applications, and can support one information channel for transmitting various media data of service application.

Description

technical field [0001] The invention relates to the communication field, in particular to a data encapsulation device and method. Background technique [0002] In the mobile communication network, the development of data service applications is changing with each passing day, and mobile multimedia broadcasting and multicasting have been derived. That is, in order to effectively utilize the bandwidth and suit the business form, many normative standards adopt broadcasting and multicasting methods to transmit business data. For example, MBMS, BCMCS, etc. [0003] Examples of these business data types include a variety of media data, such as various audio and video clips of Clipcasting services (such as weather forecasts, comedy humor, etc.), and graphic data of Data casting services (such as news, weather, astrology, etc.) , advertising, etc.). [0004] However, in solutions including MBMS and BCMCS, only limited channel resources can be provided at present. [0005] In the...
