Section: 6.1.3.12 Handling session management request for MS configured for dual priority
Content: If timer T3396 is running for a specific APN due to one of the following reasons: - an ACTIVATE PDP CONTEXT REQUEST, ACTIVATE SECONDARY PDP CONTEXT REQUEST, MODIFY PDP CONTEXT REQUEST or ACTIVATE MBMS CONTEXT REQUEST message containing the low priority indicator set to "MS is configured for NAS signalling low priority" was rejected with a timer value for timer T3396 and SM cause value #26 "insufficient resources"; - a DEACTIVATE PDP CONTEXT REQUEST message was received with a timer value for timer T3396 and SM cause value #26 "insufficient resources" for a PDP context established with the low priority indicator set to "MS is configured for NAS signalling low priority", or - because the MS received a DEACTIVATE PDP CONTEXT REQUEST message containing a timer value for timer T3396 and SM cause value #26 "insufficient resources" for a PDP context established with the low priority indicator set to "MS is configured for NAS signalling low priority"; upon request of the upper layers the MS can: - send an ACTIVATE PDP CONTEXT REQUEST or ACTIVATE MBMS CONTEXT REQUEST message to the same APN, with low priority indicator set to "MS is not configured for NAS signalling low priority"; or, - send an ACTIVATE SECONDARY PDP CONTEXT REQUEST or MODIFY PDP CONTEXT REQUEST message, with low priority indicator set to "MS is not configured for NAS signalling low priority", for an active PDP context established with low priority indicator set to "MS is not configured for NAS signalling low priority" exists. If timer T3396 is running, because any of the following messages containing the low priority indicator set to "MS is configured for NAS signalling low priority" was rejected with a timer value for timer T3396 and SM cause value #26 "insufficient resources": - an ACTIVATE PDP CONTEXT REQUEST without an APN and with request type different from "emergency"; or - an ACTIVATE SECONDARY PDP CONTEXT REQUEST or MODIFY PDP CONTEXT REQUEST message for a non-emergency PDN connection established without APN sent by the MS, or because the MS received a DEACTIVATE PDP CONTEXT REQUEST message containing a timer value for timer T3396 and SM cause value #26 "insufficient resources" for a non-emergency PDN connection established without an APN and established with the low priority indicator set to "MS is configured for NAS signalling low priority", then upon request of the upper layers the MS can: - send an ACTIVATE PDP CONTEXT REQUEST message without an APN and with low priority indicator set to "MS is not configured for NAS signalling low priority" for establishment an non-emergency PDN connection; or - send an ACTIVATE SECONDARY PDP CONTEXT REQUEST or MODIFY PDP CONTEXT REQUEST message, with low priority indicator set to "MS is not configured for NAS signalling low priority", for an active non-emergency PDP context established without an APN and with low priority indicator set to "MS is not configured for NAS signalling low priority". For requests with low priority indicator set to "MS is configured for NAS signalling low priority", the MS shall follow the procedures specified in subclause 6.1.3.1.3.
