HetNet Densification With The Casa MobileEdge Solution

Casa Systems’ MobileEdge is a market leading, next generation Heterogeneous Network (HetNet) security solution that enables mobile operators to ‘densify’ their networks and cost effectively tame their explosive traffic growth. Casa’s solution boosts indoor wireless coverage and improves voice quality in residential, enterprise and public metrocells.  Equipped with a versatile software architecture, Casa’s MobileEdge solution is ‘right-sized’ for managing applications ranging from a stand-alone security gateway for securing cell site transport connections in the first-mile to a unified Small Cell Gateway (SCG) with an integrated Security Gateway (SeGW) and a Home eNode B Gateway (HeNB-GW) for concentrating very large small cell clusters. With this pay-as-you-grow approach, operators can start small using the Security Gateway to directly attach small cell radios to their mobile core and seamlessly scale density of the radio coverage by subsequently adding HeNB-GW software licenses to shield the core network from the small cell signaling.

Casa Systems MobileEdge Evolved Packet Data Gateway (ePDG) enables mobile subscribers to enjoy the broadband experience from indoor WiFi access points in the home, office or public hotspots. Casa’s ePDG provides cost effective WiFi offload for congested macro radios while boosting in-building data capacity and addressing voice coverage holes. Casa’s ePDG provides seamless mobility and integration between mobile operators with fixed networks and service monetization opportunities for roaming agreements with wireless ISP’s. Casa Systems MobileEdge solution provides smooth integration of voice and messaging services for users with Voice over WiFi-capable devices (VoWiFi). By enabling integration with the Evolved Packet Core (EPC ), the ePDG allows mobile operators to take back control of the user experience and integrate with their existing charging, mediation and policy assets.

Casa Systems MobileEdge family of products deliver market leading, next generation, Heterogeneous Network (HetNet) security solutions, enabling mobile operators to "densify" their networks while cost effectively managing the explosive growth of their mobile traffic.

Some of Casa's MobileEdge Solution benefits are;

  • Extensible Casa MobileOS Software:  The same distributed Casa MobileOS runs compute-intensive cryptographic security functions on Casa’s purpose built hardware platforms and other Network Functions Virtualization (NFV) multi-tenant applications in a utility computing, telco cloud environment.
  • Industry leading scale & integration:  Millions of IPSEC/IKEv2 tunnels and up to 100G of encrypted throughput for SeGW, integrated SCG and ePDG offload applications.
  • Optimized Signaling Performance:  Support for thousands of subscriber and device attachments, intra-small cell and inter-RAT, inter-Tracking Area call hand-offs per-second.
  • Voice-grade Latency: The Casa MobileEdge platform offers robust latency performance, in milliseconds, for processing latency sensitive telephony services. Call handling is streamlined by leveraging a shared memory security architecture and bypassing extraneous memory copies.
  • Authentication for SIM and non-SIM User Devices: Diameter-based RSA public key signature authentication and support for EAP-AKA, EAP-TLS/TTLS procedures. X.509 certificate authentication for Casa SeGW and ePDG functional elements.
  • Robust support for IPSEC/IKEv2 Security Profiles

    • IPSEC ESP tunnel-mode support
    • Confidentiality
      • 3DEC
      • AES-CBC with 128, 192 and 256-bit keys
    • Pseudo-Random Function:
      • HMAC SHA1
      • AES128 CBC
      • AES-XCBC-PRF-128
    • Integrity:
      • HMAC SHA1_96
      • AES-XCBC-96
      • AES-XCBC-MAC-96
    • Diffie-Hellman:
      • Group 2 (1024-bit)
      • Group 14 (2048-bit)
  • DOS Prevention:


    • IKEv2 cookie challenge for filtering half-opened IKEv2 sessions
    • Dropping malformed IKEv2 or IPSEC packets
    • IPSEC NAT Traversal for tunnel establishment when a NAT device exists between a client device and Casa ePDG
  • QoS: Extension of LTE QoS treatments to WiFi attached users
    • Apply mappings from SWm interface or local policy to apply DSCP markings to IPSEC packets on SWu or S2b GTP interfaces

The Casa MobileEdge features two purpose-built hardware platforms to address the needs of different operational models:

 
ME10x
ME10x

Casa’s ME10x is the flagship product of it's performance leading, MobileEdge product family designed for high density, core Radio Access (RAN) Network applications. The ME10x meets the needs of the largest Tier 1mobile network operators and Its ability to anchor hundreds of thousands of licensed or unlicensed LTE small cells and macro-cells with millions of mobile devices is unprecedented. 

ME4x
ME4x

The ME4x is Casa's entry-level member of the MobileEdge product family.  It is designed for distributed RAN edge processing.  Casa's ME4x is right-sized for regionalized offloading of multimedia services including video streaming, VoLTE/VoWiFi and messaging.
