Voice over Long-Term Evolution (acronym VoLTE) is an LTE high-speed wireless communication standard for voice calls and SMS using mobile phones and data terminals. VoLTE has up to three times more voice and data capacity than older 3G UMTS and up to six times more than 2G GSM. It uses less bandwidth because VoLTE's packet headers are smaller than those of unoptimized VoIP/LTE. VoLTE calls are usually charged at the same rate as other calls. To be able to make a VoLTE call, the device, its firmware, and the mobile telephone providers on each end, as well as the inter-carrier connectivity must all implement the service in the area, and be able to work together. VoLTE has been marketed as "HD voice" by some carriers, but this is a broader concept. Moreover, HD+ ( EVS) is used only in LTE and NR; HD voice was available in 3G too. Overview VoLTE is based on the IP Multimedia Subsystem (IMS) architectural framework, with specific profiles for control and media planes of voice se ...

Circuit-switched
Circuit switching is a method of implementing a telecommunications network in which two network nodes establish a dedicated communications channel ( circuit) through the network before the nodes may communicate. The circuit guarantees the full bandwidth of the channel and remains connected for the duration of the communication session. The circuit functions as if the nodes were physically connected as with an electrical circuit. Circuit switching originated in analog telephone networks where the network created a dedicated circuit between two telephones for the duration of a telephone call. It contrasts with message switching and packet switching used in modern digital networks in which the trunklines between switching centres carry data between many different nodes in the form of data packets without dedicated circuits. Description The defining example of a circuit-switched network is the early analogue telephone network. When a call is made from one telephone to another, ...

Telstra
Telstra Group Limited is an Australian telecommunications company that builds and operates telecommunications networks and markets related products and services. It is a member of the S&P/ASX 20 stock index, and is Australia's largest telecommunications company by market share. Telstra has a long history in Australia, originating together with Australia Post as the Postmaster-General's Department upon Federation of Australia, federation in 1901. Telstra had transitioned from a state-owned enterprise to a fully Privatization, privatised company by 2006. History Australia's telecommunications services were originally controlled by the Postmaster-General's Department (PMG), formed in 1901 as a result of Australian Federation. Prior to 1901, telecommunications were administered by each colony. On 1 July 1975, separate commissions were established by statute to replace the PMG. Responsibility for postal services was transferred to the Australian Postal Commission (Australia Pos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
