Scenario #1: Rev A UE and Rev 0 HSGW
{"Image DocumentName": "Scenario #1: Rev A UE and Rev 0 HSGW", "Image ImageDescription": "1. The 1st PDN connection to APN-1(PDN-ID-1) 2. VSNCP configure request (NAI, APN-1, PDN-ID-2) 3. VSNCP configure Reject (error code=11) 4. UE gets to know that the HSGW doesn\u2019t support MUPSAP. Rev A UE(NAI) has established 1st PDN connection to APN-1, which uses PDN-ID-1 in VSNCP/VSNP messages. Rev A UE(NAI) sends a VSNCP configure request (NAI, APN-1, PDN-ID-2) to HSGW(Rev 0) to initiate 2nd PDN connection to APN-1 since the UE does not know whether the HSGW supports MUPSAP or not, and UE assumes that the HSGW does. After the HSGW receives the VSNCP configure request from the UE, it rejects this request with error code=11: PDN connection already exists for this APN to the UE since the HSGW does not support MUPSAP. After the UE receives the error code=11, it knows that the HSGW does not support MUPSAP, and will not request another PDN connection establishment to APN-1 until the 1st PDN connection has been released.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
