LTE (Long Term Evolution) is a data only technology but it seems that we can not live without voice or SMS services. VoLGA forum claims that VoLGA specifications fill this gap. A number of telecom companies (including Ericsson, Alcatel-Lucent, Huawei) are showing interest in VoLGA and are part of VoLGA forum.
According VoLGA stage 1 specification, The aim of VoLGA is to make traditional GSM/UMTS circuit switched (CS) services available to UEs accessing the EPS network via E-UTRAN.
The lack of native SMS over LTE support is a show-stopper for LTE dongle service. Mobile operators rely on SMS for back office customer care, provisioning and management of HSPA-dongle services. Clearly those systems need to be available to an LTE-based terminal service at launch.
For Voice calls LTE based UEs may have to wait for IMS rollout and LTE may remain data only service for longer time. VoLGA claims to fill this GAP.
