How does roaming work in LTE?
Roaming is a complicated subject that takes on added importance as we enter the LTE era. Essentially, it lets subscribers access voice and data services when traveling outside of their home network thanks to roaming agreements between different operators.
What is the name of the interface between RNC and MSC VLR?
The interface between the RNC and the Circuit Switched Core Network (CS-CN) is called Iu-CS and between the RNC and the Packet Switched Core Network is called Iu-PS. Other interfaces include Iub (between the RNC and the Node B) and Iur (between RNCs in the same network).
What are three primary concerns for securing and governing your data?
Data security is based on three foundational principles — confidentiality, integrity, and availability — which are known as the “CIA triad.” Confidentiality involves preventing unauthorized access to sensitive data to keep it from reaching the wrong people.
What are the fundamental pillars of database security?
There are 5 pillars of information security: Confidentiality, Integrity, Availability, Authenticity, and Non-repudiation.
What is LTE draw the frame structure and architecture?
LTE uses a frame structure of frames & subframes – type 1 & type 2 LTE frames – to provide the synchronisation and location for the data being carried. Like previous cellular systems, and virtually all data communications systems, LTE data is carried in frames and subframes.
What is LTE roaming architecture?
LTE Roaming Architecture. A network run by one operator in one country is known as a Public Land Mobile Network (PLMN) and when a subscribed user uses his operator’s PLMN then it is said Home-PLMN but roaming allows users to move outside their home network and using the resources from other operator’s network.
What is 3G system from 3GPP?
The 3G system from 3GPP is based on evolved Global System for Mobile communication (GSM) core networks and the radio access technologies that they support.
What are the 3GPP Technical Specification Groups?
3GPP specifications and studies are contribution-driven, by member companies, in Working Groups and at the Technical Specification Group level. The three Technical Specification Groups (TSG) in 3GPP are; Radio Access Networks (RAN), Services & Systems Aspects (SA),
What was the original scope of 3GPP?
The original scope of 3GPP (1998) was to produce Technical Specifications and Technical Reports for a 3G Mobile System based on evolved GSM core networks and the radio access technologies that they support (i.e., Universal Terrestrial Radio Access (UTRA) both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes).
