Description

A kind of method for information display based on BCMCS and TPEG

Technical field

The present invention relates to the mobile communication platform technical field, be meant a kind of TPEG encoding traffic information method for pushing especially based on BCMCS.

Background technology

Along with the development of communication service, the development of particularly various communication service technology, communication user is more and more, how to become the problem of putting forth effort to consider in the current business development process for the user provides more better service and the efficient that improves service.

Mobile communication in recent years and various correlation technique have obtained development at full speed; TPEG (Transport Protocol Experts Group) is the transport information host-host protocol that European Broadcasting Union (EBU) formulates; It has language independent, media independent, multimode application three big characteristics, and TPEG is divided into XML and two kinds of versions of binary system, and the former is used for Internet service; And can be used as the data interchange format of traffic information center, the latter then is used for the transmission of various broadcast channels.

The BCMCS technology is based on the CDMA2000 network provides audio-video-frequency broadcast professional technology.This technology can provide multicast (one-to-many provides identical content) and clean culture (individualized content is provided one to one) blended service according to user's demand.The development of BCMCS is first from unicasting to gold multicast (GoldMuhicast), evolves to the process of platinum multicast (PlatinumMulticast) then from the gold multicast.

The traffic message that can carry out logic control through the message of BCMCS platform and TPEG formating coding pushes.

In view of this, the objective of the invention is to propose a kind of simple, be prone to row, push the method for transport information through format TPEG transport information and control BCMCS system.

Summary of the invention

Saidly can find out from top; Transport information of gathering based on TPEG provided by the invention and the method through the BCMCS pushed information; Through coding that transport information is carried out TPEG and transmission parameter and the combining geographic information system that controls BCMCS; For the propelling movement of transport information provides a kind of regional efficiently method for pushing, in the customized logic that raising information pushes, improved the efficient that information pushes greatly.

Have the following advantages specifically:

Coding protocol is flexible:

TPEG has language independent, media independent, multimode application three big characteristics, and TPEG is divided into XML and two kinds of versions of binary system, can under different rates, carry out the formatted message coding respectively.

The transmission information type is various:

TPEG supports the coding and the transmission of multiple information, is not only transport information, also supports the road congestion information, describes public's trip information, describes weather conditions, describes and block up and hourage, description parking lot information.

The information pushing efficiency is high:

BCMCS supports broadcast mode, multicast mode and mode of unicast, and broadcasting has greatly been saved system resource with the multicast mode, can push information to the terminal use efficiently;

The propelling movement logic is flexible:

Through with the combining of GIS-Geographic Information System and BCMCS control system, can specify flexible service propelling logic and patterned zone set so that service logic flexibly to be set;
