Zadanie na seme3

Chcel som od nich porovnat NGN a 3GPP teoreticky
1) Architektura
    -entity
2) Sluzby
3) rozhrania a 4) protokoly

-call flow

a paralelne prakticky rozchodit OpenIMS popripade aj sluzby event notification and messaging

 

Practical OpenIMS

– Martin + Vilo + Andrej rozchadzaju IMS, dve instancie

– Maros + Palo dokumentacia

– Tomas prejde status, co ide co nejde, co riesia, co je hot topic, co by sa dalo riesit u nas

– Jozef = OpenIMS sluzby

 

27.11.

– Andrej ma default instalaciu

– 

 

Rozdelenie:

Andrej: 3gpp IMS architektura

Martin: etsi IMS arch.

Jozef: NASS

Pavol: RACS

Tomas:Service layer

Viliam + Maros: Protokoly + rozhrania

kratka 15min prezentacia + tvorenie docka

 

Andrej – IMS ppt

– detailnejsi call flow na 20.11.

– aky?- rozhodnutie do 13.11. tyzdna user oper1 na user2 oper1, user 1 oper1 na user 2 oper2 , user oper1 na user2 oper 1 ale rooming na oper2

"

Co by ma zaujimalo:

• 5.4. IMS roaming

• 5.5. IMS registration

• 5.6. IMS session control
  • 5.6.1. Session established between two IMS users in their home network
  • 5.6.2. Session established between an IMS user and a PSTN user
  • 5.6.3. Session established two roaming IMS users

"

27.11.

 – registracia call flow

–  call obaja useri v tej istej sieti

– – authorise QoS?

– roaming Call

 

Martin – NGN arch ppt

– priklad spojenia… – rozhodnutie do 13.11.

 

27.11. call flow podla etsi NGN

– medzi dvomi ims nie je definovane vychodisko pre ims ims call flow

– ok

 

Tomas – service layer ppt

– 20.11. dalsie kolo prezentacii

20.11.

– ok

 

 Jozef – NASS

– 20.11. ref. body, priklady NASS

20.11. ppt

– pozriet aky protokol na akom rozhrani

– ok

 

Pavol – RACS

– 20.11. QoS v NGN

– da sa nieco detailnejsie zistit? realizacia?

27.11.

–  vyborne

 

Viliam and Maros  – 

 – do 20.11.

– blizsie naco je a ako pracuje MEGACO/H.248

– napasovali na koncept v NGN, MGCP, S-MG, T-MG

20.11.

-ok…

 

NGN Big Picture

– vsetci spolu, priklad ako to funguje od pripojenia cez NASS, volania, AAA, Charging, QoS, NAPT, prepoj von do inej NGN, inej IP, inej PSTN,  etc, velku diagram

– kedy? koniec projektu?

 

Diplomky:

do 13.11. spravit nastrel riesenia DP,

  – prax od zaciatku, teoria priebezne
