More Information
Summary:A method, an apparatus, and a computer program product for wireless communication are provided in which blocking of LTE access due to Internet Protocol Multimedia Subsystem (IMS) Packet Data Network (PDN) recovery failure is prevented. The blocking may be caused by detach and immediate attach to LTE because of internal or other commonly executed network procedures. Recovery procedures may be modified to avoid prolong periods when access to the PDN is prevented based on long backoff delays set by an operator for PDN failure conditions. Based on a reason for failure to reconnect, a backoff period may be selected from an operator define minimum backoff time and a locally configured minimum backoff time.
