Nokia Siemens Networks introduced new functionality that enables simultaneous voice and data calls over GSM for smart device users. The new GSM network functionality also allows operators to manage up to four times more GSM devices on the existing networks.
The new functionality addresses the problem of signaling traffic generated by smart devices that automatically connect far more frequently to the network. Nokia Siemens Networks said its Smart GSM network functionality quadruples signaling channel capacity, allowing operators to handle up to four times as many devices in a single cell site. In addition, it improves GSM network efficiency by ensuring that traffic channel capacity is not wasted due to signaling congestion.
The capability enables users to receive or initiate voice calls while a data connection is active. Without support for the concurrent use of voice and data, incoming voice calls are currently diverted to the voicemail, when there is an active data connection, for instance, when the handset is downloading emails.
The new functionality can be introduced to Nokia Siemens Networks’ radio networks via simple software upgrades and is available for deployment now.
“A steady decline in prices has led to an increasing use of smart phones even in markets that are yet to move to 3G,” said Prashant Agnihotri, head of GSM/EDGE product management, Nokia Siemens Networks. “It is natural for smart device users to desire round the clock connectivity and demand high data and voice service quality, when they are in a GSM coverage area. Our new functionality will ensure that operators can meet these demands in their GSM networks without making heavy investments or affecting the experience of other users.”http://www.nsn.com
