The APN Restriction information element, when used in messages from the GGSN to the SGSN, contains an unsigned integer value indicating the level of restriction imposed on primary PDP Contexts created to the associated APN. When used in messages from the SGSN to GGSN, it contains an unsigned integer value indicating the highest level of restriction type for all currently active PDP Contexts associated with the subscriber. In both cases, the meaning of the value contained within the IE is as defined in 3GPP TS 23.060 [4], clause 15.4.
