Interaction method and device between resource and admission control systems

摘要

The present invention relates to an interaction method and device between resource and admission control systems, which is applied in a case that a mobile user equipment accesses a network at a fixed network side and deploys a service of the fixed network, the method includes: the resource and admission control system of the fixed network performing, after receiving a resource request sent from an application function of the fixed network, an authorization check on the resource request, and interacting with the resource and admission control system of a mobile network to make the resource and admission control system of the mobile network perform another authorization check on the resource request; if both the authorization checks are passed, the resource and admission control system of the fixed network formulating final policy rules, and returning a resource response to the application function of the fixed network. The device comprises the resource and admission control system of the fixed network and the resource and admission control system of the mobile network. The method and device of the present invention can solve the resource and admission control problems when a mobile user equipment accesses the network at the fixed network side and deploys a service in the fixed network.

1. An interaction method between resource and admission control systems, the method comprising:
in a case where a mobile user equipment:
accesses a fixed network, wherein the fixed network includes an application function and a resource and admission control system, wherein the application function of the fixed network includes at least one of service control functions (SCF) or an application function (AF) and the resource and admission control system of the fixed network includes at least one of admission control functions (RACF) and resource and admission control subsystem (RACS),deploys a service of the fixed network, andinteracts with the resource and admission control system of a mobile network through a resource and admission control system of the fixed network to realize policy control of the service, the resource and admission control system of the fixed network performing, after receiving a resource request sent from the application function of the fixed network, an authorization check on the resource request, if the authorization check is passed, the resource and admission control system of the fixed network transmitting the resource request to the resource and admission control system of a mobile network to make the resource and admission control system of the mobile network perform a second authorization check on the resource request after the second authorization check on the resource request is passed, the resource and admission control system of the mobile network formulating, in response to the resource request from the resource and admission control system of the fixed network, initial policy rules for the resource request, and transmitting the initial policy rules to the resource and admission control system of the fixed network; if both the authorization checks are passed, the resource and admission control system of the fixed network formulating final policy rules according to the initial policy rules, local operator policy rules and resource availability, and returning a resource response to the application function of the fixed network.
