Problems solved by technology

However, in this way, some advantages of the IP packet itself may not be reflected in the CMMB system
For example, the IP header usually carries the originating address of the data service. For interactive services, the originating address is exactly what the terminal needs. However, after the IP data packet is processed according to the existing method, since the IP header is removed, the The originating address of the data service cannot be notified to the terminal, so that the interactive service cannot be realized
It can be seen that the existing processing methods for IP data packets are not conducive to the flexible development of IP-based data services on the CMMB system

Embodiment Construction

[0035] Aiming at the problems existing in the prior art, the present invention proposes a brand-new data service transmission scheme, that is, each service identifier corresponds to multiple data services, that is to say, each service identifier is equivalent to a service set; IP data packets corresponding to each data service are encapsulated in the same multiplexing subframe for transmission, and different IP addresses are used to distinguish multiple IP data packets encapsulated in the same multiplexing subframe.

[0036] Among them, which data services each service identifier corresponds to can be preset, that is, it is pre-determined which IP data packets corresponding to data services are transmitted using multiplexing subframe 1, and which IP data packets corresponding to data services are transmitted using multiplexing subframe 1. Subframe 2 for transmission and so on. In principle, service identifiers corresponding to different data services can be arbitrarily set, bu...

Abstract

The invention discloses a method for data service transmission, which comprises the following steps: determining multiplex sub-frames used by international protocol (IP) data packets corresponding to difference data services received currently for transmission respectively; and encapsulating all IP data packets using the same multiplex sub-frame for transmission into the same multiplex sub-frame and transmitting the data packets to a terminal. The invention also discloses a system and a device for data service transmission. The method, the system and the device of the invention can realize flexible configuration of data services and facilitate the flexible operation of the IP-based data services in a China mobile multimedia broadcast (CMMB) system.

Description

technical field [0001] The present invention relates to China Mobile Multimedia Broadcasting (CMMB, China Mobile Multimedia Broadcasting) technology, in particular to a data service transmission method, system and device in the CMMB system. Background technique [0002] In the existing CMMB system, data services are distinguished according to service identifiers. Specifically, when each data service accesses data broadcasting, the data broadcasting platform will assign a service identifier to the data service, that is, establish a one-to-one correspondence between each data service and its service identifier; In order to analyze the corresponding data business. In this way, the following problems will arise: [0003] Firstly, each data service corresponds to a service identifier, and each service identifier can only correspond to one multiplexing subframe, that is, one multiplexing subframe can only transmit one data service, which is not conducive to service expansion. ...
