Diameter Routing Agent, Mobile Signaling solution-IPLOOK

Diameter Routing Agent (DRA)

A Diameter Routing Agent (DRA) is a functional element in a 3G or 4G (such as LTE) network which provides real-time routing capabilities to ensure that messages are routed among the correct elements in a network. The DRA was introduced by the 3GPP to address the increased Diameter signaling traffic and growing complexity of 4G LTE networks.

Networks with complex architectures and multiple Diameter nodes require an advanced Diameter contextual routing engine. Choosing a DRA that' s capable of advanced contextual routing is essential to managing network complexity and capitalizing on all that 4G LTE has to offer.

IPLOOK's DRA
Enable interoperability, elastic growth and congestion control 
IPLOOK offers an integrated DRA software solution dedicated to run on any hardware or cloud infrastructure for Network Function Virtualization (NFV) to cope with such new challenge of engineering Diameter traffic deeply into the Evolved Packet Core (EPC) Network. Our solution is the enabler of fluid Diameter traffic between the key components of the IMS based network architecture namely HSS, AAA Server, PCRF, OCS on one side and PCEF, MME, PGW and SGSN on the other side thanks to its combination of DRA and Diameter Edge Agent (DEA) .
IPLOOK DRA empowers operators and vendors to independently resolve signaling issues and enable advanced service scenarios, across vendor and access technologies.

»  The DRA device support static configuration of the peer, including the host name, IP address, port, etc. of the peer
»  The DRA appliance supports redundant backup or load sharing of the signaling processing unit
»  Multiple load-sharing and master Diameter links can be created between DRAs and between DRAs and other Diameter devices
»  The connection to the peer fully complies with the RFC3588 standard
»  Support peer link fault detection function, and support for failover and reversion
 Addressing strategies
Supports addressing based on the content of the following Diameter messages
»  IMSI
    »  Support multiple configurable fixed-length IMSI number prefixes for maximum matching, with priority to match by maximum length
    »  Full matching of IMSI number
»  Application ID
Diameter signaling relay function
»  Proxy Approach - Support the Relay/proxy method as defined by RFC3588
»  Type of application
    »  For relay mode, it can support the routing of all Diameter applications.
    »  For proxy mode, it supports the route of Diameter application of S6a, S6d, S13, Cx interface, and can support the route of other Diameter application through software upgrade according to the need.
    »  The proxy mode for different Diameter applications is configurable, and the proxy mode for different nodes and the type of application supported are also configurable on a node-by-node basis.

GPRS Tunneling Protocol Router(GTP-Router)
GPRS Tunneling Protocol Router(GTP-Router)
GPRS Tunneling Protocol (GTP) is a set of IP-based communication protocols used to carry GPRS (General Packet Radio Service) in GSM, UMTS and LTE networks. It enables an endpoint on a GSM or UMTS network to move its position within the network, while being continuously connected to the Internet via the same GGSN. In order to achieve this, the GTP protocol always transmits user-plane data from the SGSN to which the user's location belongs to the GGSN on which it is based.

The GPRS core network uses these three GTP protocols:
▫  GTP-U is used to provide one or more tunnels for each PDP context to transmit user data
▫  GTP-C is used for control purposes
▫  GTP is used to transfer billing data from each GGSN to the Charging Gateway Function (CGF)

Signal Transfer Point(STP)
Signal Transfer Point(STP)
A Signal Transfer Point(STP) is used in an SS7 or CC7 network. The STPs transfer SS7 messages between interconnected nodes (signaling endpoints) based on information contained in the SS7 address fields. Typical SEPs include service switching points (SSPs) and service control points (SCPs). The STP is connected to adjacent SEPs and STPs via signaling links.

STP supports any-to-any signaling connectivity between SS7 via IP SIGTRAN interfaces for maximum network integration flexibility. The STP offers all the standard features and functionality expected of an STP solution, including Gateway Screening and Global Title Translation, while also offering extended capabilities and features such as Signaling Gateway and Point Code Emulation.
