Motivation • Deployment requirement: Smooth evolution from 16 e to 16 m network SHOULD be supported. – The first release of Wimax profile supporting 16 m will be lack of network support. – That is, the Rel 1. x ASN-GW is used for not only the 16 e BS/MS but also the 16 m ABS/AMS.

The first phase deployment for Wi. MAX (from 16 e to 16 m ) The awareness of legacy ASN-GW may be configured for the ABS.

The impact to the Idle mode • • The ABS has to bridge the gap between the legacy ASN-GW and the 16 m AMS/ABS. The major differences include: – Identification • 16 m use 10 bit DID together with paging cycle, paging offset to identify the AMS within the paging group, • 16 e use the 24 bit MAC address hash to identify the AMS. – Paging groups: • 16 m AMS could belong to multiple paging groups • 16 e AMS could only belong to one paging groups – Paging listening interval: • 16 m use the number of superframe to calculate the start of the paging listening interval • 16 e use the number of frame to calculate the start of the paging listening interval – Emergency alert • 16 m AMS support the paging for emergency indication • 16 e does not support it. – DCR • 16 m AMS may terminate the idle mode due to the entering of DCR mode • 16 e AMS does not support it.

Detailed Idle mode Comparison between 16 e and 16 m

Summarized idle mode processing category • Idle initialization in LZone and paged in LZone • Idle initialization in MZone and paged in MZone

Proposed Text [Adopt the following modification in line 61 of page 306 of section 16. 2. 17 “Idle mode • To support the idle mode with the ABS connected to legacy network, an identifier that is recognizable to the network shall be used to page the AMS in MZone.
