name: ACTIVATE PDP CONTEXT REQUEST
full_form: Activate PDP Context Request Message
context: An MS configured for NAS signalling low priority (see 3GPP TS 24.368 [135], 3GPP TS 31.102 [112]) indicates this by including the Device properties IE in the appropriate NAS message and setting the low priority indicator to "MS is configured to NAS signalling low priority" except for the following cases in which the MS shall set the low priority indicator to "MS is not configured for NAS signalling low priority": - the MS is performing an attach for emergency bearer services; - the MS has a PDN connection for emergency bearer services established and is performing mobility management procedures, or is establishing a PDN connection for emergency bearer services; - the MS configured for dual priority is requested by the upper layers to establish a PDN connection with the low priority indicator set to "MS is not configured for NAS signalling low priority"; - the MS configured for dual priority is performing session management procedures related to the PDN connection established with low priority indicator set to "MS is not configured for NAS signalling low priority"; - the MS configured for dual priority has a PDN connection established by setting the low priority indicator to "MS is not configured for NAS signalling low priority" and is performing mobility management procedures; - the MS is establishing or re-establishing an MM connection for an emergency call; - the MS is an MS configured to use AC11 â 15 in selected PLMN; or - the MS is responding to paging. The network may use the NAS signalling low priority indication for NAS level mobility management congestion control on a per core network node basis and APN based congestion control. If the NAS signalling low priority indication is provided in an ACTIVATE PDP CONTEXT REQUEST message, the SGSN stores the NAS signalling low priority indication within the default PDP context activated due to this request.
description: The ACTIVATE PDP CONTEXT REQUEST message is used to activate a PDP context in the SGSN. It may include the NAS signalling low priority indication.
explanation: Classified as a Message because it is a specific type of signaling message used for activating PDP contexts.
