The invention discloses a method for transmitting data in streaming media service, which comprises the following steps: detecting data quantity in a buffer area of a current receiving end, and determining that the data quantity is greater than a first threshold or smaller than a second threshold, wherein the first threshold is greater than the second threshold; sending alarm information to a sending end, wherein the alarm information shows that the data quantity in the buffer area is greater than the first threshold or smaller than the second threshold; and adjusting the data quantity transmitted to the receiving end in unit time by the sending end according to the alarm information, and transmitting data according to the adjusted data quantity. The method makes the receiving end and the sending end timely respond to the change of data transmission quantity caused by the change of the quality of network channels so as to ensure the normal execution of the streaming media service. The invention also discloses a system for transmitting data in streaming media service, a data sending device and a data receiving device.

The invention provides an application task processing method, device and system. The method comprises the following steps of: storing background tasks of an application in a task queue; monitoring whether the application is located in an idle state or not; and when the fact that the application is located in the idle state is monitored, triggering a preset task thread to execute the tasks stored in the task queue according to a serial execution manner. According to the method, device and system provided by the invention, an application-idle task processing mechanism is proposed for the application lag problem caused by multiple tasks, so that the application starting performance and processing performance can be effectively improved. Aiming at the characteristic that terminal system resources are limited, a manner of serially executing background tasks by using single threads is proposed, so that the normal execution of the background tasks is ensured, the terminal system resources can be reasonably utilized, and the influences on foreground tasks of applications are decreased as much as possible when the background tasks are executed.

A system and method multiplexes channels over multiple connections between one or more nodes. Each node includes a cluster fabric interface module adapted to implement a novel network protocol that enables intra-cluster communication among the nodes. The network protocol is a multi-layered protocol that integrates a session infrastructure and an application operation set into a session layer. The network protocol is illustratively a request / response protocol wherein a node (requester) receiving a data access request from a client redirects that request to another node (responder) that services the request and, upon completion, returns a response.

The invention discloses a generating and distributing method of mobile IP key after reidentifying and recognizing, which comprises the following steps: the terminal and identification authorizing charging AAA server generates the main conversation expanding key EMSK in the reidentifying authorizing course; the terminal generates new relative key of mobile joint according to the EMSK, which replaces old mobile joint key; the home agency obtains new mobile IP key from AAA server, which replaces the old mobile IP key; the AAA server hands out key information to anchor identifier which obtains new mobile IP key from external agency according to the key information to transmit to the external agency; the outer agency replaces the old mobile IP key. The invention ensures the execution of MIP register after the reidentifying and authorizing course.

The invention provides a hardware energy-saving processing method. The method comprises the following steps: starting an off energy-saving mode; in the off energy-saving mode, closing hardware which is unnecessary in a working state in the current equipment, and maintaining the working state of other hardware in the current equipment. By the method and the device, electric energy can be saved as much as possible on the basis of ensuring user task execution.

The invention provides a broadcast control system for broadcast television.

The invention discloses a method for realizing overload control in a packet based network, which comprises the steps that: when a server is over loaded, a client end judges whether a current service request received meets preset service request routing conditions or not; if the current service request received meets the preset service request routing conditions, the client end routes the current service request to the server. The invention also discloses a system and a device for realizing overload control in the packet based network. The application of the invention does not means carrying out respective process according to the characteristics of the request instead of not transmitting any request to an overload server simply, thereby promoting the usability of the packet based network. Besides, the invention also ensures that session of urgency priority can be carried out.

The invention provides a parameter synchronization method and a device, the method includes: when the RCL transmits the encrypted data under a UM mode, executes the cell updataing triggerd by the wireless links; generating encryption and decryption parameter changing information and sending or acquiring the encryption and decryption parameter changing information, adjusting the local RLC encryption and decryption parameter based on the encryption and decryption parameter changing information. The device includes a module for executing the parameter synchronization method. After the cell update is triggered by the wireless links, the invention ensures the normal encryption and decryption operation when doing encrypted data transmission.

This invention relates to a quick switch realization method for multicast channels including: when a user terminal leaves the current placed multicast channel, it is judged if said position information in said multicast channel has other accessed user terminals based on the position information accessed by said user terminal and the multicast duplicate list of the related channel is maintained according to the judgment result, which realizes that there is always only one multicast flow bandwidth on a user terminal circuit and solves the problem of existing multicast flows on the circuit during the switch.
