Mobile IP. Mobile IP (or MIP) is an Internet Engineering Task Force (IETF) standard communications protocol that is designed to allow mobile device users to move from one network to another while maintaining a permanent IP address. Mobile IP for IPv4 is described in IETF RFC 5944, and extensions are defined in IETF RFC 4721.
Mobile phone tracking is a process for identifying the location of a mobile phone, whether stationary or moving. Localization may be affected by a number of technologies, such as the multilateration of radio signals between (several) cell towers of the network and the phone or by simply using GNSS. To locate a mobile phone using multilateration ...
Voice over Internet Protocol (VoIP), [a] also called IP telephony, is a method and group of technologies for voice calls for the delivery of voice communication sessions over Internet Protocol (IP) networks, [2] such as the Internet. The broader terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the ...
There are two primary types of IP addresses in use today: IP version 4 (IPv4) and IP version 6 (IPv6). ... everyone can find the company’s phone number—the external IP address in this case.
IP Multimedia Subsystem. The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is a standardised architectural framework for delivering IP multimedia services. Historically, mobile phones have provided voice call services over a circuit-switched -style network, rather than strictly over an IP packet-switched network.
An Internet Protocol address (IP address) is a numerical label such as 192.0.2.1 that is assigned to a device connected to a computer network that uses the Internet Protocol for communication. [1][2] IP addresses serve two main functions: network interface identification, and location addressing. Internet Protocol version 4 (IPv4) defines an IP ...
STUN is used in some of the sip phones to enable the SIP/RTP packets to cross boundaries of two different IP networks. A packet becomes unroutable between two sip elements if one of the networks uses private IP address range and other is in public IP address range. Stun is a mechanism to enable this border traversal.
IPv6 deployment. The deployment of IPv6, the latest version of the Internet Protocol (IP), has been in progress since the mid-2000s. IPv6 was designed as the successor protocol for IPv4 with an expanded addressing space. IPv4, which has been in use since 1982, is in the final stages of exhausting its unallocated address space, but still carries ...
