Where one has a high-speed mobile broadband network with mobile internet optimization, a subset of this network showing one connection from a mobile device to the internet is depicted in Figure 1 below. Base stations are co-located with an edge optimization device (EOD); e.g., in order to cache often requested content from the internet and serve requests for such content more efficiently (mobile internet optimization). Both - base stations and EODs - are deployed in the called radio access network (RAN) and are called herein RAN entities. The radio network controller (RNC) or any other analogous device of the mobile core network in higher versions connected to the base stations is accompanied with an optimization control device (OCD) to control the EOD's cache content and its usage. An element management system (EMS) is available for configuration management.

Core Optimization


    Elements of interest are the RAN entities (base stations and EODs). Multiples of them (assumed up to 1000) are connected to one RNC or OCD. Every RNC is connected to gateway nodes of the mobile core network providing access to the internet.

    Given the RAN entity's device numbers involved, which multiplies by many RNCs or OCDs, managing them is difficult. The automatic configuration of these RAN entities with regard to the edge location of their devices is the key aspect of this publication.

All RAN entities (base stations or EODs) are usually pre-installed identically. Necessary

specific configuration is handled via the RNC or the OCDs. For EODs, this configuration contains information needed for the mobile internet optimization functionality including the adjacent device information.

    The fresh network boot technique mainly allows the RAN entities to pull the required information needed from the element management system (EMS) level at the RNC or OCD.

    The basic approach is to boot the RAN entity system as it's available on the infrastructure network, after that the protocol will start to retrieve all needed configuration information located in the RNC or OCD located in the mobile core network it is connected to.

All configuration changes of RAN entities (including software update) will be relayed
