Reducing access latency while protecting against control signaling data processing overload
First Claim
1. A method for regulating a data processing load for control signaling associated with mobile terminals currently having a connection with a base station in a radio access network, comprising:
- determining a connection activity level for current connections between multiple mobile terminals and the base station;
determining whether one or more of the mobile terminals is likely to request a handover of its respective connection to a neighboring base station; and
determining whether to terminate the respective connection based on the likelihood of handover being requested for the respective connection and the connection activity level determined for the respective connection.

Abstract
A control signal data processing load associated with mobile terminals currently having a connection with a radio access network is regulated. The connection is terminated when the control processing cost for maintaining the connection exceeds the benefit of maintaining the connection to achieve shorter access latency. A connection activity level is determined for current connections between multiple mobile terminals and a base station. A current data processing load in the base station associated with the mobile terminal control signaling is calculated. A decision is made whether one or more of the mobile terminals is likely to request a handover of its respective connection to a neighboring base station. Based on the current load, the likelihood of requesting handover of the respective connection, and the connection activity level determined for the respective connection, a decision is made whether to terminate the respective connection.

6. The method 5, further comprising:
-
if the determined load does not exceed a first threshold, designating the current load level for the base station as normal; if the determined load exceeds a first threshold but is less than or equal to a second higher threshold, designating the current load level for the base station as loaded; and if the determined load exceeds the second threshold, designating the current load level for the base station as congested. - View Dependent Claims (7, 8, 9, 10)
