4G: Deployment Strategies and Operational Implications: by Trichy Venkataraman Krishnamurthy, Rajaneesh Shetty

By Trichy Venkataraman Krishnamurthy, Rajaneesh Shetty

As telecommunications operators and community engineers comprehend, particular operational necessities force early community architectural and layout judgements for 4G networks. yet additionally they be aware of that simply because expertise, criteria, utilization practices, and regulatory regimes swap on a continuing foundation, so do most sensible practices. 4G: Deployment recommendations and Operational Implications is helping you not sleep thus far via offering the newest cutting edge and strategic pondering on 4G and LTE deployments. It evaluates particular layout and deployment strategies extensive and provides roadmap evolution recommendations for LTE community enterprise development.

Fortunately, as you’ll realize during this e-book, LTE is a sturdy and versatile typical for 4G communications. Operators constructing 4G deployment concepts have many strategies, yet they have to think of the tradeoffs between them with the intention to maximize the go back on funding for LTE networks. This ebook will express operators the way to boost unique yet versatile deployment street maps incorporating company necessities whereas permitting the agility that anticipated and unforeseen community evolution require. Such street maps assist you keep away from expensive redeployment whereas leveraging ecocnomic traffic.

Telecommunications specialists and authors Trichy Venkataraman Krishnamurthy and Rajaneesh Shetty research quite a few architectural recommendations supplied by way of the pliability of LTE and their influence at the basic present and destiny strength of the designed community. They research particular positive factors of the community, whereas protecting particular architectural deployment innovations via instance after which assessing their implications on either close to- and long term operations in addition to power evolutionary paths.

Besides aiding you already know and speak community improve and architectural evolution street maps (with options), you are going to learn:

* easy methods to plan for accessibility, retainability, integrity, availability, and mobility
* tips on how to stability lots effectively
* the right way to deal with the limitations bobbing up from legislation and standardization
* how one can deal with the numerous disruptive components affecting LTE networks

4G: Deployment techniques and Operational Implications additionally outlines particular community recommendations, which community beneficial properties and deployment thoughts aid these thoughts, and the trade-offs in company types reckoning on the recommendations selected. better of all you are going to research a technique for proactive administration of community highway map evolution, making sure that your network—and your skills—remain strong and suitable because the telecommunications panorama alterations.

This condition can be detected at the cell that owns the neighbor list as well as at all of the neighbor cells that are using the same PCID value. Figure 2-5 shows an example of PCID confusion. Figure 2-5. , PCI 3). However, eNodeB 1 and eNodeB 3 do not have an X2 link and are not neighbors, so they cannot resolve the conflict. PCID confusion is detected by eNodeB 2, and it sends an eNodeB configuration update message with Neighbor Information IE (NI) filled appropriately to eNodeB 1 as well as eNodeB 3, which in turn would trigger conflict resolution based on its settings.

Neighbor cell detection 2. X2 configuration discovery of the neighboring site 3. The X2 connection setup 4. Neighbor relation optimization Neighbor Cell Detection An LTE cell can be identified in two ways. First, it is identified with the help of PCID, which is used for most of the RRC signaling, as it requires fewer bits for transmission. LTE cells can be identified and classified as neighbors based on the PCID; however, because there are only 504 possible PCIDs, there is a risk of a duplicate PCID being used by two different cells that are close to each other.

U Maximum number of E-RABs (default plus dedicated) that can be supported by an eNodeB without compromising the KPIs. u Number of simultaneous attaches procedures (number of attach requests per second) that can be supported by the sector without compromising the KPI requirements. u Number of incoming handovers that can be supported by the sector without compromising the KPIs. CHAPTER 1 N NETWORK PLANNING For control plane capacity testing, a test setup similar to test setup 2 is essential. For example, to test the maximum number of attached UEs per sector, the following steps will be required: u For the sector running on a no-load condition, perform a steady rate of UE attaches in steps of 32 attaches, 64 attaches, 96 attaches, 128 attaches, 156 attaches, 200 attaches, and so forth.
