UDDI Universal Description, Discovery, and Integration
E-commerce applications and services known as the "Internet Yellow Pages", was born in B2B e-commerce network crazy heyday, UDDI Web services specification is primarily used to identify and establish a network directory service to facilitate direct online to make query.
This was two years ago (2000) by Microsoft, IBM and Ariba proposed. Theoretically, in this directory of companies registered in this system as a version of Yahoo's business services. For example, an e-commerce site can use this directory database to find a mechanism to provide credit card transaction company. If found consistent, and all transactions in the process of components (including the price and payment) can be completed directly through electronic transactions. In favor of this plan say that all of the communications onto the network can greatly simplify the process and speed up business transactions.
UDDI specifications, assist in setting up Microsoft, IBM, SAP and HP now have set up websites for the Internet service was registered in the public UDDI directory database. Japan's NTT telecommunications company currently has a similar website is architecture. In theory, the higher the acceptance of Web services, software and hardware sales will increase along with.
UDDI is the composition of the four basic skills of web services, other three technologies include XML (Extensible Markup Language), SOAP (Simple Object Access Protocol) and WSDL (Web Services Description Language). As the links between them, we may wish to call to make an analogy: In the world of web services, XML to represent both the language of conversation, SOAP would provide that the rules call, UDDI is the phone book, WSDL is the standard the nature of each phone call, and how to participate.
UDP User Datagram Protocol
TCP / IP, a protocol (PROTOCOL), and TCP use the same IP as the underlying protocol, but UDP is a connectionless (CONNECTIONLESS) protocol, just add the source and destination IP address, usually used to broadcast (BROADCASTING ).
UIM User Identity Chip
In fact, what we normally well-known GSM mobile phone SIM card, but is designed specifically for CDMA phones. CDMA mobile phone number used in the past to burn method (the same as burning the previous pager code the same way), it was developed for users to change their own user code mechanism.
According to international organizations on standards developed by UIM cards, UIM cards and the GSM system using the same physical structure, logical interface and electrical properties, while according to the standard SIM card and increase the relevant parameters and directives, the industry was also suggested that, UIM card is a SIM card for further expansion.
UIM card information stored includes the user identification information, including IMSI number and CDMA system, the privacy of proprietary information, including the A-Key, SSD-A and SSD-B, etc. There is also a CDMA system, business-related information storage In the HLR, the final is, including base stations and other related information, including the use of systems and frequency bands in order to maintain the normal operation of mobile phones.
Currently, China's operators have begun to use UIM UIM-style CDMA phone, so the user ID and then the door to replace the system, they do not need to take mobile phones to stores to burn. To increase the user's convenience.
