The paper mainly discusses the functional model and the state of RRC sublayer in LTE system，as well as the connection eatablishment process of RRC sublayer when it communicates with another user normally．Traditionally there are two large states which are idle and connection．Now，it divide them into three sub-state separately．In addition，it defines the RRC to the high-level and to the underlying primitives，by the above method，it can systematically describes the connection eatablishment process of normal communication of LTE system，combined flow chart to illustrate this process．

Cloud computing security is the key issue that influences the application and development of cloud computing. Many researchers pay much attention to this issue. In this paper, we researched the reliability, availability, confidentiality, integrality, controllability and non-repudiation of cloud computing from the perspective of information security. Base on this research, we discussed and designed the secure frame of cloud computing.

With the development of visualization technology，more and more programming languages and integrated development environment use visualization techniques．However，they basically use visual programming in the software development process，not running the program dynamically with visualization．So we do some research in procedure visualization studying，and design a platform for CASL language visualization running．

The issue of students’ programming ability is researched．There are many flaws in current training systems such as the deflected objective，the backward pattern，the inadequate resources and the inconsecutive training．In this paper，all programming courses are seen as a course group and the cultivation of students’ programming ability is taken into account from the view of the overall course group．A series of measures are adopted．On the one hand，the objective and mode of education are adjusted，and the teaching resources are enriched．On the other hand，the guidance and organization of students are strengthened，and the continuity of training is ensured．Practice shows that these reform measures have yielded good results．

As the developing of 3G，it is important to improve the transferring steadiness of communication protocol between the base station controller and base station transverse in cdma2000． The article introduces the protocol between Abisc process module of BSC and data service module of BTS in base station system，and then implements the protocol stack of data service module．

In this paper，an on-line streaming player system for soundbooks is designed，the key technologies are choosen，and a player based on J2ME and MMAPI is implemented．Further，WTK2．5 is used to simulate the application result and it is showed that the effect is good．However，because of the limitation of MMAPI，this system is not designed for continous sound media，such as music．

With 3g gradually deeping into the lives of people，the major operators introduce a series of 3g services．This article introduces the 3g technology，its functions and the challenges it carries．It has some theoretical values in helping people come to understand 3g．

The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol designed by IETF for automating the configuration of computers．DHCP can be used to automatically assign IP addresses，subnet mask，default gateway and other TCP/IP parameters．Acquainting the working principle of DHCP can help us deal with problems on LAN DHCP service effectively．The article analyzes the working principle and working flow of DHCP in-depth by the packets crawled on real network．

The security problems and solutions existed are analyzed in this paper．And a new solution is proposed——Secure Telephone System．Secure Telephone System provides integrate security services：confidentiality，authority certification，integrality and anti-denying．This Security System has a good chance of wide applying to governments， military forces，banks and stockmarket．Terminal equipment of security telephone has good commercial values．
