Embodiment Construction

[0041] The preferred embodiments described below are used to illustrate the applicability and feasibility of the present invention, but it should be expressly understood that these embodiments are only illustrative examples and they should not be construed as limiting the present invention to the described detailed features.

[0042] 3GPP technical specification 23.236 ("Intra-domain connection of RadioAccess Network (RAN) nodes to multiple Core Network (CN) nodes (intra-domain connection of radio access network (RAN) nodes to multiple core network (CN) nodes)") A so-called multipoint A or multipoint Iu interface is introduced which enables an RNC or BSC to connect to multiple core network elements (both MSC / MSC server and SGSN). Thus, the resilience of the network is enhanced in case of a catastrophic failure of a specific core network element. The main rationale for these features is that the RNC / BSC is configured to communicate with pools of network elements (where circuit...

Abstract

An apparatus is configured to be operably connected to an access network controller device as well as to a pool of network elements which all comprise the same radio network configuration. The apparatus further comprises a selection functionality configured to select and connect one or more of the network elements with the access network controller device.

Description

technical field [0001] The present invention relates to an apparatus, system and method suitable for increasing resiliency in a communication network. Background technique [0002] The Mobile Switching Center Server (MSC Server-MSS) architecture is an enhancement on top of traditional circuit-switched networks, where actual user plane traffic (i.e. voice, data and fax) and control plane traffic (i.e. call and non-call related Signaling) has been divided into separate physical (and logical) entities, called Media Gateway (MGW) and MSC Server. [0003] For the network operator, this division achieves several different benefits compared to the case of using traditional MSC network elements. For example, it is made possible for the MSC server system to transfer signaling and user plane traffic in a standardized manner using Internet Protocol (IP), Asynchronous Transfer Mode (ATM) or Time Division Multiple Access (TDM) transport. This was not possible in previous cases, althoug...
