MCC ReferenceReference modelmodel forfor structuringstructuring thethe workwork • S1 defines the features and services required • S2 defines the architecture for the features and : – divides the features into building blocks. – forwards the building blocks to the relevant TSGs for the detailed work. – Interactively work with TSGs/WGs for common understanding . ReferenceReference modelmodel forfor structuringstructuring thethe workwork

• The TSGs and their WGs treat the building block as one or several dedicated Work Tasks (WT) • Typical, output of a Work Task is new TS(s), CR(s), TR(s) S2’sS2’s rolerole isis toto Co-operateCo-operate withwith thethe TSGsTSGs // WGsWGs • Identify if synergy can be obtained using some of the building blocks or extended building blocks for more than one feature. • Verify, that all required work takes place within 3GPP without overlap between groups ProjectProject schedulingscheduling • S1 sets a target • S2: – performs a first technical review and comment on the target. – indicates target for time schedule with allocation of the defined building blocks. – Aligns targets with TSG and WG comments • S1 and S2 involve S3 to ensure security StructureStructure S2 TSGs Features Building blocks Work Tasks W1 B1 B1 W2 F1 W3 B2 B2 W4

• Currently the S2 tasks are carried out by the six S2 Inter-Group Co-ordination (IGC) sub groups. ExampleExample
