stds-802-mobility: Re: stds-802-16: new 802.16 PARs for consideration in November [correction]


These are comments to help in the discussion on the PARS for consideration in November, particularly those for broadband wireless access. If the address lists used above aren't the correct ones, please circulate appropriately. Thanks.

Concern has been expressed in some of the input comments on the PAR discussion concerning the boundaries between the efforts of IEEE 802 and other standards bodies in the area of broadband standards. The impression may have been given that the current 3G standards work done elsewhere is circuit switched and not packet-based. This is actually not the case. There is significant work being done in this area in 3GPP and 3GPP2 as part of the cooperative efforts of TIA, ETSI, CWTS, ARIB, TTA, TTC and others, as the following extract of a summary of this work indicates.

Both 3GPP and 3GPP2 have been developing standards for packet based systems.  This is for both the Core Networks (CN) and Radio Access Networks (RAN).
Both 3GPP and 3GPP2 have major projects to convert their core networks to what are called All-IP networks.  These All-IP networks are based upon IETF protocols.  This work is called IP Multimedia Subsystem (IMS) in 3GPP and IP Multimedia Domain (MMD) in 3GPP2.  When these All-IP networks are fully deployed, the traditional circuit switched Mobile Switching Centers (MSCs) will disappear and any communications to traditional wireline telephone networks will be through Media Gateways (MGW).
Both 3GPPs have been developing packet based standards for the RAN.  This is for both the air interface and the land-side network comprising the BSC, BTS, and various packet gateways.
Both 3GPP and 3GPP2 have recently completed air interface enhancements that provide enhanced performance for IP packet services.  These are High Speed Downlink Packet Access (HSDPA) in 3GPP and an evolved version of TIA/EIA/IS-2000 (1xEV-DV) in 3GPP2.  In 2000, 3GPP2 completed 1xEV-DO, which is a packet data only air interface.
With the exception of the interfaces (A1, A2, and A5) to the Mobile Switching Center (MSC) all of the 3GPP2 land side interfaces are packet.  For the specific case of 3GPP2 1xEV-DO, there is not an interface to the MSC as the air interface does not support classical circuit data.  Thus, all of the interfaces are packet based.
In 3GPP, the work on core packet networks is being done in TSG SA and TSG CN.  In 3GPP2, the core network work is being done in TSG-N and in TSG-P, with TSG-P being created specifically to handle the packet domain.

Dear SEC:

I have fixed a couple of typos in the 802.16e PAR. The new version (802.16-02/48r1) is at:
