Section: 6.1.3.1.2 Successful PDP context activation requested by the network
Content: In order to request a PDP context activation, the network sends a REQUEST PDP CONTEXT ACTIVATION message to the MS and starts timer T3385. The message contains an offered PDP address. If available, the APN shall be included in the REQUEST PDP CONTEXT ACTIVATION message. Upon receipt of a REQUEST PDP CONTEXT ACTIVATION message if an APN is indicated in the message and the timer T3396 is running for the APN, the MS shall stop the timer T3396, and then either initiate the PDP context activation procedure as described in the previous subclause or reject the activation request by sending a REQUEST PDP CONTEXT ACTIVATION REJECT message as described in subclause 6.1.3.1.4. If the REQUEST PDP CONTEXT ACTIVATION message did not contain an APN, then the MS shall stop the timer T3396 associated with no APN. The value of the reject cause IE of the REQUEST PDP CONTEXT ACTIVATION REJECT message shall indicate the reason for rejection, e.g. "insufficient resources to activate another context". The ACTIVATE PDP CONTEXT REQUEST message sent by the MS in order to initiate the PDP context activation procedure shall contain the PDP address, PDP Type and APN requested by the network in the REQUEST PDP CONTEXT ACTIVATION message. Upon receipt of the ACTIVATE PDP CONTEXT REQUEST message, the network shall stop timer T3385. The same procedures then apply as described for MS initiated PDP context activation.
