Abstract
A method of enhanced session management procedure is proposed. A user equipment, upon receiving a rejected PDN connectivity request with a cause code, automatically alters the rejected factor to fit network restrictions based on the received cause code. The UE then retries the PDN connectivity procedure by sending a subsequent PDN connectivity request using the altered factor. By automatically altering the rejected factor and reattempting to establish an EPS bearer for data service without user interaction, possible permanent rejection can be avoided in case of user error or unawareness.
