Mavenir Systems and Acme Packet have created a reseller partnership to solve the inability of LTE networks to support circuit-switched voice and SMS and deliver voice services over Session Initiation Protocol (SIP).
The companies' solution adds Mavenir's converged voice messaging solutions on its mOne platform with Acme's session border controllers to create a solution that allows mobile operators to deliver next-generation services like VoIP using their legacy infrastructures. The solution is similar to what Nokia Siemens Networks has proposed. But most major infrastructure vendors support a generic access approach.
T-Mobile International and major handset and equipment vendors have joined forces to promote what they call Voice over LTE via Generic Access (VoLGA). The group is developing a common set of standards, to be submitted to 3GPP, to allow circuit-switched SMS and voice traffic to travel over LTE over a generic access approach. Kineto and some of the wireless industry's biggest vendors are founding members of the group, including Alcatel-Lucent, Ericsson, Huawei, LG Electronics, Motorola, Samsung, Starent and ZTE.
