Nokia Siemens Networks (NSN) says it has undertaken VoLTE (voice over LTE) tests using virtualized, cloud-based capabilities that included "feature parity with customers’ current 2G/3G circuit-switched voice services, Single Radio Voice Call Continuity (SRVCC) functionality and the reuse of existing billing, lawful interception and intelligent network interfaces." NSN says it used "an industry-standard virtualization and cloud management infrastructure as well as commercial off-the-shelf IT server hardware" for the tests, which were supported by its OSS systems and a cloud application management system. NSN has pinned its flag firmly to the cloud mast in recent months. (See NSN Gets Its Cloud On.)
BT is to split its Retail division into two separate businesses, BT Consumer and BT Business, from Sept. 1. The move, says the U.K. incumbent, will enable it to "better serve its customers and focus even more on delivering its strategic priorities." BT's consumer activities will be much in focus in the coming months as the operator launches its sports TV channels.
