P1900.4 scope Reconfiguration Initiation Reconfiguration decision Entities in charge of reconfiguration decisions are in scope. (Not algorithms: implementation dependent!) Reconfiguration Initiation Reconfiguration decision Reconfiguration Execution Scope of IEEE P1900.4 Reconfiguration NOT for Connection Transfer Context information collection Distributed policy based management - RAN capabilities RAN measurements Terminal capabilities Required QoS level - Reconfiguration commands for terminals and base stations Spectrum assignment Spectrum access - Handover IEEE P1900.4 specifies architecture and information model to enable policy-based management for optimized radio resource usage in heterogeneous wireless networks

IEEE 802.21 scope Handover Initiation Handover Decision Handover Preparation Handover Execution Scope of IEEE 802.21 NOT a Decision Algorithm Setup New Link and Initiate HO Execution NOT for Connection Transfer Search New Link - Network Discovery - Network Capabilities Discovery - Handover Decision Making - Layer 2 Connectivity - Generic Handover Commands - L2 and IP Handover Signaling (not MIP) - Context Transfer IEEE 802.21 is an enabler/toolbox for having seamless handovers IEEE 802.21 is an abstraction layer between access technologies & mobility management solution

1900.4 System Architecture (2) Network side entities Operator Spectrum Manager (OSM) is the entity that enables operator to control dynamic spectrum assignment decisions of NRM RAN Measurement Collector (RMC) is the entity that collects RAN context information and provides it to NRM Network Reconfiguration Manager (NRM) is the entity that manages CWN and terminals for network-terminal distributed optimization of radio resource usage and improvement of QoS RAN Reconfiguration Controller (RRC) is the entity that controls reconfiguration of RANs based on requests from NRM Terminal side entities Terminal Measurement Collector (TMC) is the entity that collects terminal context information and provides it to TRM Terminal Reconfiguration Manager (TRM) is the entity that manages the terminal for network-terminal distributed optimization of radio resource usage and improvement of QoS within the framework defined by the NRM and in a manner consistent with user preferences and available context information Terminal Reconfiguration Controller (TRC) is the entity that controls reconfiguration of terminal based on requests from TRM

IEEE 1900.4 principles Decision making in this standard is based on policy-based management framework. 1900.4 specifies architecture and information model to enable policy- based management. 1900.4 enables to describe policies of type Event-Condition-Action Radio resource selection policies create the framework within which TRMs will make terminal reconfiguration decisions =>1900.4 may reuse handover initiation and handover preparation Services defined by 802.21.

P1900.4-802.21 differences 802.21 deals with handover of mobile terminal. Can be network initiated or mobile initiated. P1900.4 scope is broader: reconfiguration of terminals but also of base stations P1900.4 defined a policy-based management and describes policies of type Event-Condition-Action

P1900.4-802.21 complementarities P1900.4 can use a subset of 802.21 (by defining a specific 1900.4 profile) P1900.4 NRM and TRM can be seen as 802.21 MIH users P1900.4 can reuse the service concepts of 802.21 but needs the extended information model specified in 1900.4.

Conclusion 802.21 for handover initiation, decision making and target network preparation 1900.4 defines policy-based framework for reconfiguration decisions The policies defined in 1900.4 framework may be policies that trigger Handover decisions. Complementary standards
