1 A Seamless Migration from to LTE Using the Core Network
2 Table of Contents Introduction The Core Using the Core to Manage Services to Subscribers Migrating the network to an LTE network Securing the Border Between the Core and the LTE Network But I Thought You Needed an IMS Core to Deploy LTE? Adding Mobility to the LTE Network via an IMS Core Network Tying It All Together: Global Services Conclusion Introduction The widespread adoption of smartphones and tablet devices is changing the way that subscribers see their service providers. Unlimited voice services no longer command premium pricing, but are viewed as table stakes in a broader service offering that must now include multimedia (voice, data, video) communications with a mobility component. As a result of this shift, many service providers are adopting a -based, Long Term Evolution (LTE) network strategy to deliver this multimedia experience to their subscribers. While LTE is today seen as the most viable of the mobile multimedia network architectures, it has never been the only architecture. As recently as 2008, was viewed as a logical, long-term architecture to deliver IP voice, data and video over wireless networks. Today, as the industry shifts its attention to LTE and Voice over LTE (VoLTE) networks, early adopters are looking to migrate their network strategy away from the model to the more broadly adopted LTE model. Although both and LTE leverage IP/-based core networks, an IP Multimedia Subsystem (IMS) core is often implicit in an LTE strategy because of its suitability for providing Service Consistency and Continuity (SCC) within the VoLTE sub-model. Yet the adoption of LTE does not require a similar adoption of VoLTE and, in cases where a service provider plans to continue offering fixed-only voice services through their existing Voice over Broadband (VoBB) model, there is no requirement to migrate from the existing VoBB core to an IMS core. This whitepaper seeks to explain how a service provider can migrate from a network to an LTE network in a seamless, secure and cost-efficient manner. Specifically, this paper reveals how a core network from Networks can enable such a migration by allowing service providers to leverage the same core network elements whether deploying a, LTE or VoLTE network. The Core For more than a decade, Networks has built and deployed core networks for many of the world s leading service providers. The key network elements of the core solution are proven in some of the most demanding voice networks and include the GSX9000 High-Density Media Gateway, SBC 9000 Session Border Controller, Centralized Routing and Policy Server, SGX Signaling Gateway and ASX Feature Server. For the purposes of our case study, we ll assume that Company A has a core configuration that includes the following and Partner elements. SBC 9000 Session Border Controller (SBC) for connectivity to the and secure connectivity to the IP cloud Server for centralized session routing and policy management SGX2000 signaling gateway for SS7 connectivity with the ASX server (including the ADS subscriber database server) for the management and delivery of essential Class 5 features including call waiting, call forwarding, etc. Element Management System and DataStream Integrator for centralized network management and billing mediation, respectively Insight Customer Portal () for web-based subscriber provisioning of call features/services Foundry switching equipment for the interconnection of VoIP core elements Iperia Voic VX servers Radisys Convedia media server for various services (IP-PBX, IVR, contact center, etc.) 2 3
3 Using the Core to Manage Services to Subscribers In our example, Company A has already deployed a remote network for the purpose of delivering wireless broadband access that includes VoBB service to fixed (but not mobile) phones. Subscribers within the network receive their voice services through a non-ims client based on the RFC 3261 specification. Mobile phone services are made available to these subscribers on a separate GSM network that partners with Company A. For their part, Company A does not provide any mobile voices services through its own network and has no immediate plans to do so, instead adopting the model of a Mobile Virtual Network Operator (MVNO). The network is connected to the core network via a third-party Access Service Network (ASN) Gateway as depicted in the following illustration: The network currently provides wireless broadband data access and both residential and business voice services to fixed, -based phones. A key criterion of the core is the ability to maintain service consistency between the two networks. That is, subscribers on the network must share the same voice service experience as the VoIP and subscribers who access the core directly for services. This is achieved in the above example by hosting all subscribers and services on two geographically distinct (but centrally managed) ASX/ADS servers. Figure 1 core network connected to a remote network WiMax to LTE Migration Core and the LTE Network Securing the Border Between the Although the ASX Feature Server is a highly scalable and robust platform designed to support millions of subscribers, it is not designed to function as a border security or session management device. In order to provide load balancing and protect the core network from Denial of Service (DoS) attacks and other security threats, recommends using the SBC 5200 as an Access SBC between the core and the LTE network (see figure 3). The SBC 5200 provides a proven, scalable solution for secure IP-to-IP interconnect between core and access networks, including: Protection against DoS and Distributed DoS attacks Media and signaling encryption Load balancing and overload controls, H.323 and IPv4/IPv6 interworking Media transcoding for HD and non-hd media codecs Figure 2 to LTE Migration with Service Consistency via ASX Migrating the network to an LTE network In its migration from to LTE, Company A will need to preserve the same VoBB services for both sets of subscribers. During this migration, Company A has the option of connecting ASX/ to their existing network and ASX/ to the LTE network they re building (see figure 2). Such a scenario gives Company A two alternative migration paths: Build an LTE network in the background and, when it s ready for deployment, turn off the network and turn on the new LTE network Deploy the LTE network and gradually migrate subscribers to the LTE environment, keeping both networks operational in parallel for a period of time. WiMax to LTE Migration For Throtting and DOS attack Figure 3 to LTE Migration with Service Consistency via ASX and Security via Access SBC 4 5
4 But I Thought You Needed an IMS Core to Deploy LTE? In our example, Company A has elected not to deliver mobile voice services through the LTE network but will instead continue to deliver the same fixed-line VoBB services that are already offered through the network. Where mobility is not a requirement, VoLTE and VoBB are identical in functionality, and thus can utilize the same core network (see figure 4). Company A has elected instead to enter into an MVNO relationship with a third-party GSM network operator, and no IMS core is required because Company A is not concerned with managing the mobile handoff between the GSM and LTE networks. NOTE: In cases where mobility is a requirement, VoLTE should be deployed with a 3GPP-defined IMS core network in conjunction with a legacy GSM network. This configuration provides not only the service consistency between the IMS core and GSM access networks, but also provides the requisite service continuity as mobile subscribers roam between LTE and non-lte coverage areas. For Throtting and DOS attack Adding Mobility to the LTE Network via an IMS Core Network Since we ve introduced the notion that Company A will partner with a third-party GSM operator to deliver mobile services, let s take it to the next logical step and imagine that Company A would like to bundle those services into a continuous subscriber experience. This is a more common VoLTE scenario and will require an IMS core architecture to provide a Service Consistency and Continuity (SCC) framework to manage sessions as they move between the core network, LTE network and the third-party GSM network. Fortunately for Company A, core elements are designed to transition seamlessly into an IMS architecture (see figure 5), fulfilling key functions within the IMS core as follows: The SBC 5200 which, as an Access SBC, provides interoperability between the IMS and LTE networks and can serve multiple, additional roles within the IMS architecture including: Proxy Call Session Control Function (P-CSCF) Access/Core Border Gateway Function (A/C-BGF) Figure 4 Core with Access SBC Deployed with LTE network Access Transfer Control Function (ATCF) and IMS Access Gateway (IMS-AGW) for voice call continuity Emergency CSCF (E-CSCF) for E911 and other emergency services The ASX Feature Server, which can be converted into a Telephony Application Server with a simple software upgrade to support: The SBC 9000, which can be upgraded via software to serve the roles of: Media Gateway (MGW) and Media Gateway Controller (MGCF) Interconnect Border Control Function (I-BCF) and Interconnect Border Gateway Function (I-BGF) The Centralized Routing and Policy Server, which can be upgraded to serve the Border Gateway Control Function (BGCF) between the IMS core and the circuit-switched GSM network The SGX Signaling Gateway, which would continue to act as an interconnect device to the SS7 network with no upgrade required In addition, works with partners to bring in the necessary IMS pieces for a best-of breed solution including: Radisys Convedia Service Consistency and Continuity Application Server (SCC AS) Interrogating CSCF (I-CSCF) Serving CSCF (S-CSCF) Tying It All Together: Global Services Over the years, Global Services has developed best practices for the effective migration of communications networks that take into account network planning and architecture, subscriber data migration, SBC migration and other key technical considerations.

Network Migration Services include: Subscriber data migration, integration and configuration Risk management rollback procedures Signaling, gateway ad call routing design modifications Legacy equipment provisioning modifications SS7/C7 signaling link installation and migration Class 3/4/5 trunk installations and migration Conclusion Networks provides a cost-efficient and seamless migration path from to LTE networks through its unique core architecture. By leveraging existing core network elements, service providers can protect their investments in hardware, architecture and internal skill sets. In addition, the solution allows service providers to have more flexibility with their LTE deployment including: The ability to run and LTE networks in tandem using the service consistency features of the ASX server A secure border between the LTE and core networks via the SBC 5200 A simple, seamless migration from core to IMS core that supports Service Consistency and Continuity. The IMS Service Control (ISC) interface to the Serving CSCF (S-CSCF) Integration with the IMS core The Sh interface to the ADS database or, if desired, for migration to a Home Subscriber Server () database 6 7
