GL Announces SGSN Pooling within GPRS Gb Interface Emulator
GL Communications Inc., announced today its enhanced
GPRS Gb Interface Emulator referred to as MAPS™ GPRS Gb Interface Emulator software that now supports the emulation of BSC and SGSN with SGSN Pooling feature where each BSC is connected to a SGSN pool.
- (1888PressRelease) June 20, 2017 - Gaithersburg, Maryland, USA - Speaking to the press, Mr. Karthik Ramalingam, a Senior Manager for product development of the company said, “MAPS™ GPRS Gb supports Gb interface simulation between the Base Station Subsystem (BSS) and the Serving GPRS Support Node (SGSN) over IP transmission protocol. Emulation over Frame Relay transmission protocol will be supported in future.”
He added, “With the latest release, MAPS™ GPRS Gb supports SGSN Pooling feature to permit customers emulate, test, and verify GPRS Gb functionality. Besides testing network elements (SGSN and BSS), the tester also involves error tracking, regression testing, and load testing/call generation. MAPS™ GPRS Gb interface Emulator supports various procedures including Network Service Control, Identity Check, Combined GPRS / IMSI Attach, and Routing Area Update. It can run pre-defined test scenarios against the interface test objects in a controlled & deterministic manner.
MAPS™ GPRS Gb Interface Emulator supports powerful utilities like Message Editor, Script Editor, and Profile Editor which allow new scenarios to be created or existing scenarios to be modified as per the protocol standards supported.”
Mr. Ramalingam further explained, “The SGSN in Pool solution overcomes the strict hierarchy which restricts the connection of a BSC node to just one SGSN. It introduces a new routing mechanism which allows a BSC belonging to an SGSN Pool connect to all SGSNs in that pool. This permits an MS roam freely without a need to change the serving SGSN. An SGSN in the SGSN Pool serves all the routing areas (RAs) in the pool area and shares the traffic of this area between each other.
SGSN Pooling solution provides the following benefits: With the introduction of Pool feature, Multiple SGSN nodes can be deployed in a network, and an instance of a single SGSN failure will not be an issue any more as another SGSN node within the Pool will serve the request from the BSCs. Easy to increase capacity by adding SGSN nodes to a Pool and Reduced Signalling and Increased Coverage Area: i.e. coverage area served by the SGSN Pool would be large enough to decrease the Inter-SGSN routing area update procedures, handovers and relocations that help in reduced signalling.”
He added, “ GL's MAPS™ GPRS Gb provides the following SGSN Pool features: User configurable number of SGSN Pool, User configurable number of SGSN within a Pool, SGSN Pool Identifier, NRI configuration, NAS Node Selection Function, and Load Balancing.”
