The maturity of the mobile phone market is causing fierce competition between early market entry and new mobile phone manufacturers. As the market growth slows down, mobile phone manufacturers are increasingly competing for alternative services. The result is that there are only two ways for mobile phone manufacturers to take a lead, either in cost reduction or in performance. However, in all these circumstances, this trend has forced all manufacturers to fully optimize development and BOM costs

usable. that's why the concept of SIP proxy exists: the proxy is responsible for routing cballs whatever the IP address of end-users is. voIP OperatorsCompany are deploying sip proxies on the Internet to get sip callrouted for their subscribers. Direct Dialing is not always available on the internet due to changes in IP addresses, firewalls, and other factors. this is why there is a sip Proxy: The SIP proxy can implement the routing function without considering the user's real IP address. voIP

In the past, most of China's 2G mobile phone businesses were concentrated on voice and text messages, so the operators and manufacturers at both ends of the value chain did not find too many matching points. In most cases, mobile phone manufacturers do not have much product differences, and operators have little right to decide on mobile terminals. With the emergence of smartphones, carriers began to produce custom mobile phone demands, which can comb

App Store is a required course for modern Operators Article/author of rush to digitalization App Store (mobile phone software download store) has become the main sales model of modern mobile phone software. It is also one of the strategic support points for carriers to transform to the network. Entering the network is a consensus between current operators and communication enterprises.

Omit irrelevant content ...... The above is a very small part of the telephone communication protocol. The materials are too long. Do you think it is a bit dizzy? It doesn't matter. I will give you a simple picture to explain. Actually, there are many similarities between this stuff and Internet communication protocols. I wil

Internet, operators will spend hundreds of of dollars a month. The Schiaberelli airport in Amsterdam, Holland, has Wi-Fi equipment that is used by only more than 10 people a day. However, its operators still believe that as long as a number of "hot spots", the use of equipment will be greatly increased. They follow the logic of the Internet frenzy "as long as it is built, people will come." ” Perhaps the high price is the reason for the consumer to stagnate. It is after a new round of price cu

There are still many things worth learning about the IP router technology. Here we will mainly introduce the experience of IP phones and IP router technology. There are still many problems to solve when the IP Phone is transferred to the local device. There will be many policy issues to solve, such as operating licenses. There are also problems that need to be solved in different technical and policy fields such as number resources and interconnection between networks. Apart from these problems,

At present, there is no technical problem in upgrading from IPv4 to IPv6. The problem is the industrialization of technology. If we do not push the core technology of computing to industrialization, the final result will be that a pot of good meat will not be able to produce practical significance. Industrialization of IPv6 is a business related to the future of the country and the fate of the enterprise. It is not enough to rely solely on a research institution such as the Institute of computin

With the unprecedented iPhone success and Apple's arrogant and harsh attitude towards network operators, carriers are eager to find a cheaper option; therefore, the largest operators at the first layer began to use android to develop mobile phones for users who could not afford the iPhone.
