TESTE DEIN WISSEN

What is convergence? Give an educated example of convergence?

Lösung anzeigen
TESTE DEIN WISSEN
  • The act of converging and is moving toward union or uniformity;
  • the merging of distinct technologies, industries, or devices into a unified whole
  • ex. 1 2G/3G which are two different mobile technologies but are using the same core network
  • ex. 2 Networks like industrial networks, critical networks, Fixed telephony, satellite networks will use a common 5G core
  • non tech: coordinated movement of the two eyes so that the image of a single point is formed

What are the benefits of convergence?

Lösung anzeigen
TESTE DEIN WISSEN
  • The cost of deployment is highly reduced  

  • The cost of management and maintenance is reduced

  • A single infrastructure has to be deployed

What are the opportunities brought by convergence?

Lösung anzeigen
TESTE DEIN WISSEN
  • To offer a unique global interconnection network for all the communication services and all the communication needs with a reduced cost

  • Possibility to address new markets where the previous networks were too expensive

What are the main limitations of convergence?

Lösung anzeigen
TESTE DEIN WISSEN
  • A system does not fit all: 

    • Different governance – the systems are administered differently 

    • Different configuration – the systems have a different deployment 

    • Functionality Customization – different functionality is needed

  • The added-value  

    • Two competitive systems will try to differentiate between them through the creation of added-value services 

    • e.g. remote voice box, answering machine 

    • The larger the difference, the easier is for the operator to create an own image 

    • At one moment. The system requires to be though not as an old system with    added value, but as a new system all together

Lösung anzeigen
TESTE DEIN WISSEN

1. flexibility

2. customizability

3. micro service architecture

4. softwarization/virtualizuation

5. Split between control and user plane

6. Edge computing

Describe the network function, the network infrastructure or the integrated perspectives on 5G

Lösung anzeigen
TESTE DEIN WISSEN

Network Function Perspective:

  • The 5G system is a distributed system

    • The network functions should be able to understand the underlying connectivity

    • Network functions should be properly synchronized

  • The 5G system is a software system

    • Performance depends on the underlying uncertain infrastructure

  • New mechanisms for ensuring the flexibility and the security

    • With different levels of trust on the infrastructure


→ The 5G system should be adaptable enough to run (reliably and secure) on the available infrastructures

TESTE DEIN WISSEN

What should be done to integrate satellite networks or autonomous backhaul?

Lösung anzeigen
TESTE DEIN WISSEN
  • Control plane split

  • Adaptation of data path

  • Dynamic network mgmt.

  • Support for local services

  • Leveraging multicast
