Section: 6.1.3.1.6 Handling Activate PDP context request for MS configured for dual priority
Content: If a PDP context exists that was created due to a request including a low priority indicator set to "MS is configured for NAS signalling low priority" and the upper layers of the MS request to activate a PDP context with the same APN and the low priority indicator set to "MS is not configured for NAS signalling low priority", when initiating the PDP context activation procedure, the MS shall: - send an ACTIVATE PDP CONTEXT REQUEST message with the same combination of APN, PDP type and PDP address as the existing PDP context to activate a PDP context; NOTE 1: This option relies on the network handling of abnormal cases as specified in subclause .1.5 case c). - send an ACTIVATE PDP CONTEXT REQUEST message with the same combination of APN and PDP type as the existing PDP context but with a different PDP address, or without PDP address, to activate a PDP context; or - send an ACTIVATE PDP CONTEXT REQUEST message with the same APN after the successful deactivation of the existing PDP context. NOTE 2: The above list of options also apply for the case when the existing PDP context was created due to a request including a low priority indicator set to "MS is not configured for NAS signalling low priority" and the new request to activate a PDP context with the same APN contains a low priority indicator set to "MS is configured for NAS signalling low priority". As an alternative the upper layers of the MS can request to activate a PDP context with a different APN.
