In which scenario of LTE wildcard APN is used?

Question

Can't find how many max APNs UE shell support simultaneously, please share the thoughts. Is there a relation with number of bearer?

Answer 1

It is somewhat related to UE subscription. If wild card APN is configured in HSS then UE can access any of the APN/service of that network. If a list of APN is configured for an UE in HSS then UE can access services provided by listed APN only.

Comments

The APN field in the HLR may contain a wild card APN if the HPLMN operator allows the subscriber to access any network of a given PDP Type. If an SGSN has received such a wild card APN, it may either choose the APN Network Identifier received from the Mobile Station or a default APN Network Identifier for addressing the GGSN when activating a PDP context.
