5G an der TU Berlin

• 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

• The cost of deployment is highly reduced  

• The cost of management and maintenance is reduced

• A single infrastructure has to be deployed

• 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 

• 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

• Fixed telephony

• Mobile telephony

• Internet access

• TV & Content Distribution

• 2G/3G with common core network

• Wifi/LTE have a common core network

• Critical/emergency networks, Industrial networks, V2X(Vehicle to anything) networks

• Home automation, remote control

• Operator wide AAA functionality

• QoS insurance

  • Network Availability – Coverage

  • Radio Resource Reservation

  • Device Power Control

  • Predictable service with guaranteed and non-guaranteed resources

• Mobility support

  • Ubiquitous services

  • Zero packet loss handover support 

  • Guaranteed service

• 4-Nines – active 99.99% of the time:

  • 52,6 minutes downtime per year

  • Lower than typical operator network (which is 5,26 minute per year)

1. Exploit higher frequencies and unlicensed spectrum

2. Enhance multi-RAT coordination

3. Support multi-operator/shared use of infrastructure

Network:

1. Minimize number of entities and functionalites

2. C/U-function split

3. Fixed and mobile convergence

Operations & Management

1. Automation & self healing

2. Collaborative Management

3. Integrated OAM functionality

• x1000 data volume / geographical area
