Business course transmitting layer requesting resource method in next generation network

Abstract

A method for transmitting request resource from service layer to transmission layer in next generation network includes adding refusal reason and helping to regulate resource request information when resource distribution request of service layer device is refused by transmission layer device, regulating resource to be requested by service layer device according to newly added information in response message and consulting with CPE protocol if it is necessary then reissuing request, reporting current resource state to service layer device by transmission layer device and deciding to regulate resource requirement or not by service layer device according to current resource state when session is set up.

Description

technical field [0001] The invention relates to the next generation network technology, in particular to a method for requesting resources from the service layer to the transport layer in the next generation network. Background technique [0002] Next Generation Network ("NGN" for short) is a milestone in the history of telecommunication, and it marks the arrival of a new generation of telecommunication network era. From the perspective of development, NGN has gradually taken steps from the traditional circuit switching-based public switched telephone network (Public Switched Telephone Network, referred to as "PSTN") to packet switching. With all the services of the PSTN network, a large amount of data transmission is offloaded to the Internet Protocol (Internet Protocol, referred to as "IP") network to reduce the load of the PSTN network, and many new and old services are added and enhanced with the new features of IP technology. business. [0003] In this sense, NGN is t...

Problems solved by technology

[0016] In practical applications, the above solution has the following problems: once the business layer fails to request resources from the transport layer, the entire session establishment will fail, affecting the success rate of session establishment

[0017] The main reason for this situation is that after the service control function requests resources from RACF, it only returns two statuses of the request being accepted or rejected to the service control function, and does not report the reason for the rejection and the relevant information to help the service control function adjust the resource request. Information such as existing network resource status, user subscription information in NAAF, etc. In this case, the service control function will not adjust the resource request again, but directly tear down the session, resulting in a low success rate of session establishment
