If yes, the CN controls the signaling and the user-plane data is directly forwarded to another call party; otherwise, the base station processes a signaling and the user-plane data is directly forwarded to another call party via the base station.

Abstract: Adjusting RAN performance by adapting cell coverage area can help optimize a wireless communications network. RAN topology can be adapted based on analysis of real-time load conditions of RAN base stations. Analysis of the load conditions of RAN base stations can be performed in a core-network of a wireless carrier rather than distributing the analysis to RAN-side elements.

Abstract: The teachings herein provide authorization control enabling the co-existence of legacy mobile terminals (20) that do not support Closed Subscriber Groups (CSGs), and non-legacy mobile terminals (20) that do. New behaviors are defined for a CSG femtocell base station (10) (referred to as a Home NodeB or HNB), and for a base station gateway (14) (referred to as a HNB Gateway or HNB GW) that couples the HNB (10) to a Core Network (CN) (22). The HNB (10) and/or the HNB GW (14) determine whether a terminal (20) attempting to gain connection through the HNB (10) supports CSGs. If not, the HNB GW (14) performs access control and rejects the connection attempt if authorization fails. If the terminal (20) is recognized as supporting CSGs, the HNB GW (14) defers access control to the CN (22) by automatically accepting registration/connection requests from the HNB (10) for CSG-capable terminals (20). In such cases, the CN (22) is relied upon for access control, including any CSG authorization of the terminal (20).

Abstract: A base station (BTS) may instruct a client station (CS) to transmit sounding signals that the BTS may analyze to determine what adjustments, such as power, time, and/or frequency adjustment(s) should be made by the CS. The BTS may control when and how the sounding signals are sent by the CS. This helps reduce the possibility of adjustment signals transmitted by two or more CSs colliding. Thus, sounding signals transmitted by the CS in response to a request by the BTS can be received by the BTS with higher a probability of success. This permits the BTS to more accurately characterize the channel and to provide better adjustment of power level, frequency offset, and/or timing offset for more optimal communication. Such techniques can be used to reduce bit error rates and to improve the overall signal to noise ratio encountered by the system.
