4 Areas of Interest4 Areas of Interest

These are the basic areas where E3 partners areconcentrating on:

� Self-Organizing Network featuring future evolvement of organizing the functions for 3GPP RANs (incl. single /multiple RAN cases)

� Enhanced Terminal Autonomy with respect to radio link management in heterogeneous RAN environments (3GPP RAN as well as Wi-Fi, WiMAX or other RANs)

� Technology for Autonomous Cognitive ad-hoc Radio Systems (with opportunistic spectrum access)

� Long- and mid-term Dynamic Spectrum Assignment


What else at highest level in E3?What else at highest level in E3?

“Inherited” from E 2R

� Reconfigurable equipment as pre-condition for implementation of the new envisaged functions (RCM)

Required Enablers

� Ability for spectrum sensing and exchange of sensing results as enabling technique to make spectrum rela ted decisions

� Provision of constraints and/or policies concerning the radio resource (incl. spectrum) usage to the radios involved (Abstract data for a Cognitive Pilot Channel )

Self-Organizing Network for 3GPP RANs


Different understanding of SON/SelfDifferent understanding of SON/Self --xx

� Self Organizing: From the wording often understood as a kind of autonomous management in a system (pattern: Observe –Decide – Reconfigure)Self Organizing Network: Narrow the system scope to a n etwork�� Self-x is part of almost all functional building bl ocks!

� SON is the title for a number of activities in 3GPP, NGM N, IEEE 802.16, internal T- Mobile project, …Thus, there is strong interest to dedicate a functiona l buildingblock to the corresponding identified functions in op erated RANs – this should be reflected in the functional arch itecture overview

Capabilities and use of CCRCapabilities and use of CCR

� Types of communication on CCR⇒ Broadcast to neighbors over a limited number of hops⇒ Acknowledged packet transmission to a one-hop neighbor⇒ Transmission over multiple hops to an individual destination

• Routing needed• In mobile environment finding and keeping up routes

consumes a lot of resources

� Use of CCR1. Finding own network2. Getting regulatory policy information3. Sharing spectrum sensing results and TX/RX parameters4. Negotiation about spectrum use between networks


Fitting CCR in the complete pictureFitting CCR in the complete picture

� CCR is an enabler for the new type of Autonomic Cognitive Mesh Network

� CCR provides (among other things) constraints and/or policies concerning the spectrum usage in the band(s)/sub-band(s) admitted for the Cognitive System. This is a kind of ‘restricted’CPC. It also re-distributes the information from the centralized CPC (how and where this information is received from outside the CS is not in the scope – it must only be ensured)

Functional Architecture covers the following aspects:

� Context awareness related functions: Information Extraction, Collection, and Storage at both NRM and TRM

� Reconfiguration Decision and Control for both Network and Terminal (located respectively in NRM and TRM)

� RAN Selection function in both NRM and TRM for enabling communication between NRM and TRM

� Radio Resource Selection Policy Derivation in NRM

� Policy Efficiency Evaluation in NRM

� Spectrum Assignment Evaluation in NRM

networks, Bayesian, …)� Specification Tools and Techniques (UML, ASN.1, etc .)


Self-x Pattern Discussion

� How Decision Making is triggered?⇒ Periodically⇒ On event⇒ Request

� How Decision Making is made?⇒ Optimization algorithm with fixed number of

calculations⇒ Optimization algorithm with dynamic number of

operations⇒ Optimization by investigating large context data

(learning) � Time limits for Decision Making and Reconfiguration

⇒ (ms, s, min order of magnitude)
