Abstract
The invention is related to radio resource usage in cellular telecommunication systems, more accurately to admission control methods used in establishing of new connections. In a method according to the invention, a bearer request is checked with two different tests before it is admitted or rejected. A test of a first kind is used for overall control, i.e. all bearers are treated in a roughly similar way. A test of a second kind is used for controlling bearers, which present a high load to the network. A bearer request must then pass a combination of a test of the first kind and a test of the second kind in order to be admitted. A two-part test according to the invention is able to efficiently handle both even and skewed traffic.
Claims9
An admission control method for handling bearer requests in a cellular telecommunications network that supports bearers that are allowed to comprise controllable load components in addition to non-controllable load components, the method comprising the steps of:
- testing a bearer request with a first kind of test that sets same criteria;
- and
- testing said bearer request with a second kind of test;
- wherein said first kind of test monitors non-controllable load components, and said second kind of test monitors bearers that present to the network a non-controllable load component which exceeds a predefined threshold, and the admission of said bearer request to the network depends on results of both said first kind of test and said second kind of test.
A network element for a cellular telecommunications network that supports bearers that are allowed to comprise controllable load components in addition to non-controllable load components, the element comprising:
- means for testing a bearer request based on a first kind of test that sets same criteria in a similar way for all bearer requests, and for producing a first test result, said means being adapted to handle requests for bearers that are allowed to comprise controllable and non-controllable load components, and said means being adapted to monitor non-controllable load components with said first kind of test;
- means for sequentially testing a bearer request with said first kind of test based on a second kind of test that monitors bearers that present to the network a non-controllable load component which exceeds a predefined threshold, and for producing a second test result;
- and
- means for deciding whether the bearer should be admitted to the network based on said first and second test results.
