Erlang Capacity of Multi-Access Systems with Service-based Access Selection
2004 (English)In: IEEE Communications Letters, ISSN 1089-7798, Vol. 8, no 11, 662-664 p.Article in journal (Refereed) Published
In this letter, we provide the lower and upper bounds of Erlang capacity of multi-access systems supporting several different radio access technologies in the multi-service scenario, by considering two extreme operation methods; separate and common operation. In a numerical example with GSM/EDGE-like and WCDMA-like sub-systems, it is shown that the common operation method can provide up to 60% Erlang capacity improvement over the separate operation method when using a near optimum so-called service-based user assignment scheme, with the combined effects of the assignment and the trunking gains. Even in the worst-case, the common operation method still can provide about 15% capacity improvement over the separate operation method, which mainly comes from the trunking gain.
