GAITHERSBURG, Md., October 10, 2017 (Newswire.com) - GL Communications Inc., announced today its enhanced 3G and LTE Lab Solution to support Voice, Video and IMS calls with roaming User Equipment (UE) in the network.
Speaking to the press, Mr. Jagdish Vadalia, a Senior Manager for product development of the company said, “Recent enhancement to MAPS™ Wireless Lab Suite (2G, 3G, 4G, IMS) includes ability to simulate Roaming procedures across 3G and 4G networks. Roaming 3G/4G UEs ensures that a traveling wireless device (typically a cell phone) is connected with the network continuously without losing the connection.”
He added, “With GL’s Wireless Network Lab, you can simply simulate Roaming 3G/4G UEs and test certain functionalities by automatically placing and receiving voice calls, send and receive data, or access other services when traveling within or out of the geographical coverage area of the network. Real mobile phones can also be used with GL’s Wireless Network Lab suite to create a real-time Wireless Network Environment.”
Recent enhancement to MAPS™ Wireless Lab Suite (2G, 3G, 4G, IMS) includes ability to simulate Roaming procedures across 3G and 4G networks. Roaming 3G/4G UEs ensures that a traveling wireless device (typically a cell phone) is connected with the network continuously without losing the connection.
Mr. Vadalia, further emphasizing on the recently added test scenarios, explained “MAPS™ 4G IMS Wireless Lab can simulate various nodes in the LTE IMS network, interacting with each other facilitating a VoLTE call. In the lab test scenario, two LTE enabled UEs are used to establish a VoLTE call via MAPS™ 4G Wireless and IMS Lab.”
Circuit-switched fallback (CSFB) is a technology devised to allow Voice services. LTE doesn't support circuit switched calls because LTE is packet-only technology. So, when a LTE device is used to place a voice call or send SMS, the device “falls back” to the 3G or 2G network to complete the call or to deliver the SMS.
The SGs Application Part (SGsAP) is used on the SGs interface between the Mobility Management Entity (MME) in the EPS and the Visitor Location Register (VLR). It allows location management co-ordination and relays certain messages related to GSM circuit switched services over the EPS system.
GL’s MAPS™ CAMEL IP Emulator can be configured as SCF and SSF entities emulating CAP supplementary services such as unified messaging, and prepaid calls. For example, CAP controls SMS as a subscribed service, establishes a relationship between the MSC and the gsmSCF. Initial DP SMS (IDP-SMS) operation is used to start the CAMEL service. The prepaid voice call procedure specifies the charging-related information to be provided by the SSF and the conditions on which the information should be reported back to the SCF.
