Call flow in GSM refers to the sequence of events that occur during a phone call in a GSM network.

• The call is initiated by the caller and a request is sent to the nearest base station.

• The base station sends the request to the Mobile Switching Center (MSC) which then routes the call to the recipient's network.

• The recipient's network sends a signal to their phone to alert them of the incoming call.

• If the recipient answer...read more

Routers and switches are network devices that operate at different layers of the OSI model. They have different functions and use different protocols and configuration commands.

• Routers operate at the network layer (Layer 3) and are responsible for forwarding data packets between networks.

• Switches operate at the data link layer (Layer 2) and are responsible for forwarding data frames within a network.

• Routers use routing...read more

Handover is the process of transferring responsibility from one person or team to another. There are two types: internal and external handover.

• Handover is the transfer of responsibility from one person or team to another.

• Internal handover occurs within the same organization or department.

• External handover involves transferring responsibility to a different organization or department.

• Examples of handover include passing...read more

Modulation techniques are methods used to encode information onto a carrier signal for transmission.

• Modulation techniques are used in various communication systems.

• Some common modulation techniques include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM).

• AM modulates the amplitude of the carrier signal to encode information.

• FM modulates the frequency of the carrier signal to encode inform...read more

SIP call flow is the sequence of steps involved in establishing, maintaining, and terminating a Session Initiation Protocol (SIP) call.

• SIP call flow involves several steps such as registration, session establishment, media negotiation, and call termination.

• The call flow typically starts with a SIP client sending a REGISTER request to a SIP server to register its address.

• To initiate a call, the caller sends an INVITE re...read more
