We introduce a transport selector function to handle the interaction of application with the multiple transport options. The transport selector helps determine what type of transport e.
ICN or IP as well as type of radio interface e. LTE or WiFi or both is used to send and receive the traffic. Application layer can make the decision to select a specific transport based on preference e.
ICN function forwarder is introduced in parallel to the existing IP layer. Interest packet to eNodeB or response "data packet" from eNodeB to the application. Figure 7 below provides a high level protocol stack description where ICN is used at two different layers: 1.
Removal of GTP protocol stack is significant change in mobile architecture because GTP is used not just for routing but for mobility management functions such as billing, mediation, policy enforcement etc. Native implementation will also provide opportunities to develop new use cases leveraging ICN capabilities such as seamless mobility, UE to UE content delivery using radio network without interactions with mobile gateways, etc. UE can initiate data traffic using any of three different options: 1.
Native ICN 3. In order to support ICN natively in eNodeB, it is proposed to provide transport selector capabilities in eNodeB similar as provided in UE , which provides following functions: 1. It decides the forwarding strategy for user data request coming from UE. The strategy can make decision based on preference indicated by the application such as, congestion, cost, quality of service, etc. PGW is an Prakash, et. Entire functionality is managed using IP address es for UE.
Session management layer is used for performing attach procedures and assigning logical identity to user. UE selects the either of the identities during initial attach procedures and registers with network for session management. For native IP capable UE there is no change. Protocol configuration options information elements described in [ TS Security Considerations To ensure only authenticated UEs are connected to the network, LTE mobile network implements various security mechanisms.
From perspective of ICN deployment in user plane, it need to take care of following security aspects: 1. UE authentication and authorization 2. Radio or air interface security 3. Denial of service attacks on mobile gateway, services 4. Content positioning either in transport or servers 5. Content cache pollution attacks 6. Secure naming, routing, and forwarding 7. Application security Security over the LTE air interface is provided through cryptographic technique.
In case of provider owned backhaul, it may not implement security mechanisms; however, they are necessary in case it uses shared or a leased network. For ICN based user plane traffic, it is required to integrate ICN security for session between UE and gateway; however, in ICN network, since only consumers are in possession of decryption keys can access the content, some of the services provided mobile gateway mentioned above may not work.
Further research in this area is needed. Different deployment options described covers aspects such as inter- operability and multi-technology, which is a reality for any service provider. It is important to understand that for the actual deployment scenarios, additional research study is required to identify dependencies specific to a mobile network. As far as control plane signaling is concerned, our observation is that further research is required to understand the benefits of using ICN to complement or replace traditional control plane signaling.
As a starting step towards ICN deployment, it is recommended that the focus should be on enhancement of user data plane. The key aspect for ICN is in its seamless integration in LTE and 5G networks with tangible benefits so that we can optimize content delivery using simple and scalable architecture. Authors will continue to explore how the ICN forwarding in MEC could be used in efficient delivery of unicast and multicast traffic.
Aug'e, G. Carofiglio et al. This release was introduced as a Fig. Two [3, p.
Joint Transmission describes two or more points transmitting in the 4 control element to the UE . LTE User Plane [2, p. These skills are normally acquired and improved as 1 Radio Resource Control RRC the number of years of experience increases.
The flowchart in figure one summarizes requirement for network planning especially for virgin networks. Market Modelling Market modeling is nontechnical but very important phase in network planning. This is applicable to a virgin network green field and is usually done only once in the initial phase of deployment.
This stage includes data collection of the proposed market for the LTE-advanced network. The data needed at this stage is the business plan of the network operator, demographic database and geographic information system GIS of the proposed market. The approximate classes of people in the area of interest need to be known, it may be based on income level, occupation, literacy level and age bracket.
Wireless Network Strategy This aspect is dependent on many factors like available or 2 Packet Data Convergence Protocol PDCP licensed bandwidth, deployment strategy like infrastructure This protocol deals with the IP header compression User sharing or agreement with property owners, Vendor Plane , encryption and integrity protection Control Plane equipment selection commercial and non-technical may be only.
The RF propagation characteristics, interface transmission and in addition, it performs error frequency re-use pattern and interference management are correction with Automatic Repeat Request ARQ method.
A simulation can 4 Medium Access Control MAC be conducted with use of equally spaced cell sites eNBs with This protocol performs scheduling, priority handling, the smallest radius of coverage expected for deployment, free physical layer retransmission and multiplexing of different space propagation and GIS information.
The frequency and logical channels to a single transport channel . Driving testing with planning kits is strongly aim of enhancing data transmission within the network.
In recommended at this stage to capture out of bound and LTE-A, carrier aggregation has necessitated some changes in external interferences.
The network planner must specify the the physical and MAC layer procedures. Network Planning Based on the on the result obtained from the step one and two, the number of required cell sites can be estimated, deployment strategy and spectrum usage techniques. The Fig. Wireless Network Planning flow chart[1, p. In morphology method, scanty measurement is environment is the error. Measurement Analysis measurement will suffice. The duration of the testing is not as much important as the analysis of the measured result, as this The measurement is analyzed for both stationary and will determine the performance of the network.
It will be movement to see the effect of fast fading on the channel. The pertinent at this point to note that most of the planning process result is divided into Calibration lot and control lot, the model reviewed and yet to be reviewed have software tools that can is calibrated using calibration lot while control lot is to check aid the planner to carry out most of the functions discussed.
The choice of the software tool is mainly determined by the F.

Network Optimization vendor selected for deployment. Optimization can either be done prelaunch or post launch of The calibration of propagation model is done using the the LTE-Advanced but it is a process that outlives the statically measurement of path loss obtained over the spread of lifecycle of the planned network.
This is so because even the the network coverage area. The antenna heights, elevation, best planned network requires constant adjustment may be due signal distant and different morphology should be considered to changes in network demand or the population of the area when selecting a candidate site.
The measurement must be and some of the assumed parameters need to be adjusted to done over the entire radio environment like rooftop different reality. The major goal of network optimization is to based on the following ; optimize the eNB footprint, minimize interference with enough overlap for handover, generate neighbor list and calculate handover thresholds and finally generate interference matrix IM.
The footprint improvement can be done by adjusting antenna parameters like antenna type, azimuth, downtilt, height and transmit power. The summary of general network plan discussed thus far is summarized in Table I. Nominal Network Planning The LTE-Advanced is not different from the general The nominal planning objective is the prediction of number planning of mobile networks discussed thus far but in this of sites eNBs required to cater for or surpass the target QoS.
The area of interest may parameters and planned environment. LTE-Advanced be divided into clusters and each clusters can be further be planning can be classified into Nominal planning Link budget divided into dense urban, urban, suburban and rural areas.

Demographic C. That's the reason I rated 4 not 5. Hardcover Verified download. Good product, quick delivery. I started reading this book to enhance my knowledge about LTE protocols. The first thing came to my mind while reading is, this book is written like an IEEE paper and not reader friendly.
You have to run through the pages to find lots of abbreviations which could easily be avoided. Every chapter started with unknown terms e. The writer could have describe little bit of many things and make my life easier.
While writing a good book, it is not how much knowledge you have rather you have to see everything through the eyes of your weakest reader and write accordingly.
Radio Protocols for LTE and LTE-Advanced
I read few chapters of this book and found this is one the best books for Protocol stack I ever read. The problem with most of other books for LTE s that they talk about L1 or lower layers, whereas no other book talk about protocol stack as much this book does. In addition, I want to add that this book is very easy read and very well organized. One person found this helpful.
