indicates that a pdp context has been deactivated this mih event service may be applicable to any type of standard such as ieee 802 21 and the like table 2 identifies specific 3gpp service primitives for each of the layers of the umts 140 and the lte system 145 shown in fig1 according to the present invention the 3gpp service primitives generated by the umts 140 via the nas 130 and the as 135 as well as the 3gpp service primitives generated by the lte via the e utra e core system 150 are mapped to mih event services e g ieee 802 21 events as shown in table 2 below fig1 is an example of mapping a 3gpp service primitive to an mih event service when the nas 130 indicates that a station is attached as indicated by table 2 above the processor 205 in the sap 100 illustrated in fig2 outputs a link parameter change event service in response to receiving a 3gpp service primitive from the nas 130 that indicates that a station is attached this mih event service may be applicable to any type of standard such as ieee 802 21 and the like fig1 is an example of mapping a 3gpp service primitive to an mih event.
