VANC VoLGA access network controller

Last updated on 


However, I can provide you with information about VoLGA and the Access Network Controller (ANC) concept.

VoLGA (Voice over LTE via Generic Access):

VoLGA stands for Voice over LTE via Generic Access. It was an early approach for enabling voice services over Long-Term Evolution (LTE) networks. Before the introduction of Voice over LTE (VoLTE) technology, LTE networks primarily focused on providing high-speed data services, while voice calls were typically handled by legacy circuit-switched 2G or 3G networks (e.g., GSM or UMTS).

VoLGA was designed to allow mobile operators to continue using their existing circuit-switched infrastructure for voice services while transitioning to LTE. It provided a way to carry voice calls over an IP-based LTE core network while maintaining backward compatibility with the circuit-switched infrastructure.

Access Network Controller (ANC):

In the context of wireless networks, an Access Network Controller (ANC) is a key network element responsible for controlling the access to the core network for mobile devices. It acts as an interface between the access network (e.g., radio access network) and the core network.

The main functions of an Access Network Controller typically include:

  1. Authentication and Authorization: The ANC verifies the identity of the mobile devices and grants access to authorized users.
  2. Mobility Management: The ANC handles tasks related to the mobility of mobile devices, such as handover between different base stations or access points.
  3. Quality of Service (QoS) Management: The ANC ensures that the appropriate quality of service is provided to different types of traffic, such as voice, data, and video.
  4. Security: The ANC enforces security measures to protect the network from unauthorized access and potential threats.
  5. Policy Enforcement: The ANC applies network policies and rules to manage traffic and resources effectively.
  6. Session Management: The ANC handles the establishment, maintenance, and termination of data and voice sessions.

Combining VANC and VoLGA:

As mentioned earlier, there is no specific technology or standard known as "VANC VoLGA Access Network Controller." It's possible that you might be referring to the concept of integrating a VoLGA solution with an Access Network Controller (ANC) to enable voice services over LTE.

The integration of VoLGA with an ANC would have allowed mobile operators to deploy VoLGA technology while maintaining seamless interoperability with their existing access network infrastructure. However, it's important to note that VoLGA was not widely adopted as a solution for voice services over LTE, and it was eventually supplanted by Voice over LTE (VoLTE) technology, which became the standard for delivering voice services over LTE networks.
