Method and system for controlling admission in mobile communication networks, related network and computer program product therefor

摘要

A method for controlling admission of calls to a mobile communication network having cells associated with at least one determined threshold level of operation suitable for managing cell shrinking phenomena. The method includes the operation of detecting call requests from a cell edge affected by such cell shrinking phenomena, variably exceeding the determined threshold level in uplink. A method for admitting calls to the mobile communication network in both uplink and downlink on the basis of the evaluation of the actual system load is also proposed. Preferred application is in UMTS mobile networks.

主权项

1. A method for controlling admission of calls to a mobile communication network having cells, wherein the mobile communication network includes a resource and at least one predetermined threshold load level of operation wherein exceeding said predetermined threshold load level results in cell coverage holes, the method comprising:
detecting a current load level value in uplink or downlink; comparing the current load level value with said predetermined threshold load level; and admitting a call to said mobile communication network by allowing exceeding said predetermined threshold load level if after the admitting of the call, the mobile communication network is able to:
maintain existing calls already in progress; anddetect new call requests coming from the coverage holes.
