This study is linked to the RAN4 Study on 3G Home NodeB/eNodeB (UID_350039) and to the SA5 Study on Self-Organizing Networks (SON) related OAM interfaces for Home NodeB (UID_360007).

H(e)NB is able to provide new services with higher data rate in a low cost. Operators have already indicates their interest in this area. Study of H(e)NB has already started in 3GPP in order to investigate the feasibility of developing a standard solution for H(e)NB. Security is an critical aspect of H(e)NB, but it is not sufficiently covered by the existing work items.

This work studied special security threats of H(e)NB and countermeasures to these threats.

The study included threat analysis of H(e)NB, mutual authentication and security protection between H(e)NB and rest of network, maintenance of the security context between H(e)NB and rest of network, security requirements on the H(e)NB, provisioning of security credentials on the H(e)NB, security solution for verifying the location of the H(e)NB etc. With regard to security protection between the H(e)NB and the rest of the network, bandwidth efficiency had been taken into consideration.

In the Logical Layered Architecture (LLA) of TMN, Network OSF concerns management at network level and Element OSFs concerns management at Network Element level. These two logical layers respectively play the role of network management function.

The Element Management System (EMS) developed by vendors mainly covers network management functions described in E-OSF and / or N-OSF.

TS 32.101 states that the Element Manager (EM) has two functions element management and sub-network management. However, 3GPP SA5 32.xxx-series do not provide a clear definition for E-OSF to help operators and vendors clarifying what is required when deploying a network.

An EM provided by a vendor implements E-OSF logical functions and may or may not implement N-OSF functions. Even more, the Network Management System (NMS) may or may not direct access NE and implement part of E-OSF. Whether NMS implement or not any E-OSF and whether EM implement or not any N-OSF is outside the 3GPP scope. Mapping rules between physical (EMS, NMS) and logical entities (E-OSF, N-OSF) is outside the scope of this study.

E-OSF definition is based on network operation and maintenance experience and considers the UMTS application environment. Existing 3GPP documentation does not provide sufficient E-OSF guidelines to operators and vendors.

TR 32.819 defines what is needed in E-OSF. The intention was not to define new requirements for standardization of new Interface IRP and/or NRM IRP and/or System Context.
