What is MME in telecom?
LTE MME is responsible for initiating paging and authentication of the mobile device. It also manages the signaling between cells and supports roaming.
What is the difference between CS and PS?
A circuit switching network is used for voice communication which requires dedicated connection between calling and called party to take care of latency requirements of real time voice calls. A packet switching network is used for data communication which does not require dedicated connection.
What is PS and CS in LTE?
A circuit switched call is a type of phone call that is originated on a mobile network and then carried over the air to another phone or computer. A packet switched call is a type of phone call that is originated on a computer and then carrying over the internet to another phone or computer.
What is an IP engineer?
IP Network Engineers are responsible for designing, implementing and maintaining a company's or organization's IP Ethernet network. They provide all necessary technical assistance to operation groups around the clock as needed. Their job is to help manage the network and help keep your business running smoothly.

These benefits include: -You can create a strong and central network for your organization, reducing the need for extra hardware. -You can use a Windows Server core network to connect devices in your environment, making it easier to manage and maintain your infrastructure. -The Windows Server core network can provide you with the essential services required for your IT needs.
Which one is a component of PS core network?
It is important to note that the PS domain comprises the functional entities: serving GPRS support node (SGSN), gateway GPRS support node (GGSN), domain name server (DNS), dynamic host configuration protocol (DHCP) server, packet charging gateway, and firewalls. The PS domain is responsible for providing network services to the devices in a network. The SGSN provides GPRS support, while the GGSN provides DNS and DHCP services. The packet charging gateway provides network access to devices that need to be charged for data traffic, while the firewalls help protect devices from unauthorized access.
How does 5G core work?
Usually, a 5G network uses a cloud-aligned service-based architecture in order to support authentication, security, session management and aggregation of traffic from connected devices. This requires the complex interconnection of network functions, which can lead to some challenges. For example, it may be difficult to keep track of who is working on a given project and when they will finish it.
What is converged packet core?

Mavenir also offers generational support for all G's, giving businesses the ability to move data and applications to 5G without any disruptions or upgrades.
What is LTE architecture?
Usually, when describing a high-level network architecture, one would focus on the User Equipment (UE). The UE is the device that uses the network and makes connections with other devices. It can be a phone, laptop, or even a home router. The Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) is responsible for delivering data to the UE over terrestrial radio waves. It includes layers 1 and 2 of the 3rd Generation Partnership Project (3GPP) standard, which are designed to reduce network congestion and increase data throughput. The E-UTRAN also includes support for LTE Advanced features such as 5G Long Term Evolution (LTE-A). The Evolved Packet Core (EPC) provides the core layer of an LTE network. It contains the baseband, modulation and signaling layers, as well as application layer functionality. The EPC is also responsible for handling eight radio channels per band and supporting beamforming and frequency division multiplexing.
What is LTE call flow?
Most LTE call flows navigate over the elements of the network going through certain steps in order to complete its end-to-end signaling from the user equipment (UE) all the way to the rest of the network components. This allows for a smooth and reliable experience for users, regardless of where they are in the network.
What is HSS in telecom?
When a Home Subscriber Server (HSS) is connected to a WebLogic SIP Server (WLSS), the HSS can communicate with the WLSS to manage calls and sessions. The HSS can use the WLSS to store user profiles, handle callbacks, and manage chat messages.
What is core network in LTE?
It is the key node in an LTE network that provides a backbone for all other nodes in the system. The EPC is responsible for providing mobility management, authentication, session management, and setting up bearer connections.
How MME is selected in LTE?
UE selects an available MME to serve the device, based typically on network topology and the location of the UE within the network. This allows for the best MME to be selected, reducing the probability that the MME is changed.
Why packet switching is better than circuit?
Packet switching is an efficient way to manage data traffic. It doesn't have to worry about limited bandwidth, which can slow down your system.
What is packet and circuit switching?
Circuit switching is a type of switched network that allows multiple devices to communicate with one another. This type of network is used in many scenarios, such as when you need to connect different devices in a large office. Circuit switching is connectionless, which means that the devices connecting to it don't have to be connected in order for the communication to happen.
How does packet switching work?
A packet switched network can be fault tolerant because it breaks messages up into small pieces known as packets. Each packet is sent separately across the network. The recipient takes each packet, makes a note of its number and then puts it into the correct order.
What are EPS services in LTE?
LTE EPS requires the establishment of a ?virtual? connection between two endpoints (e.g. a UE and a PDN-GW) which is called an EPS bearer. This virtual connection provides a bearer service, i.e. a transport service with specific QoS attributes.
Is LTE circuit switched or packet switched?
LTE (4G) is a new network that uses packet switching. This means that the voice and SMS services must be moved over to a packet switched network when using the LTE (4G) network. This is because the LTE (4G) network does not have any circuit switched support.
What is PSTN and ISDN?
The PSTN phone number is equivalent to one phone line. ISDN or Integrated Services Digital Network provides digital transmission of voice and data services. Although now it is primarily used for Voice as it give you the options of having more than one Channel (line). The PSTN phone number can be used for calls from anywhere in the world, even if you are not located in the United States.
What is the difference between PSTN and VoIP?
Usually, when you speak to someone on the public switched telephone network (PSTN), the conversation is held over a circuit-switched telephony network. This type of communication is used for the duration of the call, unlike voice over internet protocol (VoIP) which uses packet-switched telephony.
Why is PSTN still used?
It is reliable for emergency services like 911. The PSTN is great for when the electricity is out, because the lines haven't been damaged.
