Problems solved by technology

[0005] It can be seen that there is only one serving radio network controller in the prior art, and when the serving radio network controller fails, each corresponding drift radio network controller processes and sends the multimedia broadcast service content independently, and the entire synchronization area will Synchronous transmission of multimedia broadcasting service information cannot be realized, and serious interference between systems is caused, and there is a risk of single point failure

Embodiment 1

[0039] like Figure 4 As shown, Embodiment 1 adopts the core network as the control center 1. Here, the core network is used to send multimedia broadcast service content to the main serving radio network controller 21, and receive the fault indication sent by the main serving radio network controller 21. , and send an active / standby switching instruction to the standby radio network controller 22 and the drift radio network controller 23 corresponding to the active serving radio network controller 21 .

[0040] In practical applications, such as Figure 5 As shown, an operation and maintenance background 4 can also be included. Before the system transmits and processes multimedia broadcasting service content, an operation and maintenance background 4 can also be used as the corresponding main service radio network controller 21 and standby service radio network controller 22. The same physical channel, transport channel and data radio bearer configuration as that of the drift...

Embodiment 2

[0042] like Figure 6 As shown, the control center 1 includes the core network and the operation and maintenance background:

[0043] The core network is used to establish a data synchronization bearer with the corresponding main serving radio network controller or standby radio network controller, and send multimedia broadcasting service content;

[0044] The operation and maintenance background is used to receive the fault indication sent by the main serving wireless network controller, and send the active-standby switching instruction to the corresponding standby wireless network controller and the drift wireless network controller, so as to provide the corresponding active serving wireless network controller The device, standby service radio network controller and drift radio network controller are configured with the same physical channel, transmission channel and data radio bearer configuration.

[0045] A multimedia broadcast service transmission method involved in the...

Abstract

The invention relates to a system and a method for transferring multimedia broadcasting service. The system comprises a control center, at least one mutually separate synchronous transmission unit and user equipment, wherein each synchronous transmission unit comprises a main service wireless network controller, a standby service wireless network controller and at least one drifting wireless network controller. The method includes the steps that the main service wireless network controller detects the self working state; the main service wireless network controller and the standby service wireless network controller corresponding to the main service wireless network controller are shifted when a failure happens; and the standby service wireless network controller builds up a bearing relationship and substitutes the main service wireless network controller to process and send the content of the multimedia broadcasting service. The system and the method can be widely applied to a generation three mobile communication system.

Description

technical field [0001] The invention relates to information synchronous transmission technology, in particular to a multimedia broadcasting service transmission system and method. Background technique [0002] Multimedia Broadcast Service (MBMS) is a technology that transmits shared network resources from one data source to multiple targets. A service with great application prospects in the third-generation (3G) mobile communication system, this service enables mobile terminal users to receive broadcasted content in the form of channels or channels on intelligent mobile terminals with operating systems and video functions. Digital audio and video content (such as TV, etc.). [0003] Such as figure 1 As shown, in the multimedia broadcast service system based on Time Division Synchronous Code Division Multiple Access (TD_SCDMA, TimeDivision-Synchronous Code Division Multiple Access) mode, the content provided by the provider passes through the broadcast / multicast service cen...
