Method for managing service policy in a telecommunications network

摘要

A method for managing the service policy applied to a black network comprising a radio link and to a red network connected to this black network managed by a predetermined set of profiles is proposed. The congestion of the radio link is detected by any means by the black domain. The congestion of the radio link is detected by a method for detecting congestion which operates by means of exchanges within the red domain. A service policy profile then established matches for each domain to a detected congestion level.

1. A telecommunication network, said network comprising a first security domain, called black domain, comprising at least one radio link, at least one second domain with higher security, called red domain, connected to the black domain,
said telecommunication network including:
a first predefined list of profiles, each profile of the first predefined list containing a set of parameters applicable to the management of the service policy for the black domain, the profiles of the first predefined list being adapted to respective congestion levels on the radio link;a second predefined list of profiles, each profile of the second predefined list containing a set of parameters applicable to the management of the service policy for each red domain, the profiles of the second predefined list being adapted to respective congestion levels on the radio link; said first and second predefined lists being predefined so that a service policy profile correspond to a detected congestion level, for all domains and in a consistent manner between the domains, the parameters of the profiles of the first and second predefined lists being defined according to the topology of the black domain, wherein, once the first and second predefined list of profiles are established in their respective domains, the black domain is configured for:
performing a first detection of congestion level on the radio link in the black domain;selecting a first profile among the profiles of the first predefined list, the first profile being adapted to the congestion level of the radio link detected in the black domain; and wherein, once the first and second predefined list of profiles are established in their respective domains, each red domain is configured for:
performing a second detection of congestion level on the radio link in said red domain, said second detection being based solely on exchanges of messages in said red domain; andselecting a second profile among the profiles of the second predefined list established in said red domain, the second profile being adapted to the congestion level of the radio link detected in said red domain.
