What is 3G call flow?

What is 3G call flow?

Call flow describes the process by which a network routes a call to a mobile device. Even LTE devices still use 3G networks for most voice calls. 3G call flow is different in a GSM network than in a CDMA network.

What is call establishment procedure in 3G?

A 3G UMTS originating voice call setup involves complex signaling to set up and release the call. RRC (Radio Resource Control) signaling between the UE and RAN sets up the radio link. RANAP (Radio Access Network Application Part) signaling sets up the session between the RAN and the Core Network (MSC).

How does a call flow work?

Put simply, a Call Flow is an agent’s road map that tells them exactly which direction they need to follow from the minute they answer the phone until the end of the call. This map includes directions such as what questions to ask, which actions to perform, and whether the call needs to be escalated to a manager.

How does 2G call work?

While radio signals on 1G networks are analog, radio signals on 2G networks are digital. Both systems use digital signaling to connect the radio towers (which listen to the devices) to the rest of the mobile system. In North America, Digital AMPS (IS-54 and IS-136) and cdmaOne (IS-95) were the main systems.

What is GSM call flow?

GSM Call Flow (GSM Originating Call) RR connection establishment is triggered by sending the Channel Request message. This message requests the Base Station System (BSS) for allocation for radio resources for the RR connection setup. The mobile now waits for an assignment on the Access Grant Channel (AGCH).

What is 4g call flow?

The call flow in the LTE network is unique among mobile communication standards and represents the signaling and sessions established across the network.

What is 1G mobile technology?

1G refers to the first generation of wireless cellular technology (mobile telecommunications). The main difference between these two mobile cellular generations is that the audio transmissions of 1G networks were analog, while 2G networks were entirely digital.

How does a 3G UMTS originating call setup work?

A 3G UMTS originating voice call setup involves complex signaling to set up and release the call. RRC (Radio Resource Control) signaling between the UE and RAN sets up the radio link. RANAP (Radio Access Network Application Part) signaling sets up the session between the RAN and the Core Network (MSC). Click on the image to see the full call flow.

What is the call flow in SIP H.323?

The call flow includes the authentication procedure between the SIP client and server. All messsages in this flow can be clicked to access complete message structure. The call flow diagram presents the flow of an H.323 call. Covers: H.225/Q.931 Call Setup; H.245 Negotiation and Voice Path Setup; RTP/RTCP Based Voice Communication

What does RANAP do in the call flow?

RANAP (Radio Access Network Application Part) signaling sets up the session between the RAN and the Core Network (MSC). Click on the image to see the full call flow. You can click on most RANAP messages in the call flow to complete field-level details of the RANAP messages.

What is call flow?

A call flow is a road map to how calls will be handled from the moment they enter the phone system to the end of the call. Call flows can be used to handle even the most complex call scenarios and enable great customer care.

What is LTE call flow?

The LTE call flow navigates 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.

What is MT voice call?

A mobile message routed from a client or an application and delivered to the end user’s mobile phone is a called a SMS MT (Mobile Terminated). The word Terminated means that the message is terminated (delivered) on a mobile device. It is also known as an Outbound SMS.

How do you make a call flow diagram?

How is handover from GSM to WCDMA performed?

The same way handover from GSM to WCDMA network is also performed. The difference here is that measurement report is sent by GSM mobile terminal to the GSM network (BTS). The information reaches to the core network. As core network is interconnected between both the RATs (GSM and WCDMA), it plays a vital role to perform handover between RATs.
