Abstract:
A system and method for preventing the occurrence of a signaling deadlock between a SGSN and a GGSN during an overlap of the functionality of the direct tunnel normal release and the direct tunnel error indication procedures is provided. An indication that the error is caused by a normal release of tunnel resources instructs the GGSN to invoke an error handling procedure to mitigate deadlock by delaying the operation of its error indication procedure.
