This message, at a minimum, is used to report the ac

20、cessibility of an MS following a postponed SMSRequest or SMSDeliveryPointToPoint. This message may also be used to revoke delivery permission previously granted with either an SMSRequest or an SMSNotification. The SMSNotification operation is initiated with a TCAP INVOKE (LAST). This is carried by a

21、 TCAP QUERY WITH PERMISSION package. The Parameter Set is encoded as follows: Table 96 SMSNotification INVOKE Parameters jMSNotification INVOKE Parameters Timer: SNT Notes: a. b. These parameters are mutually exclusive; however, one must be present. Included to indicate the temporary routing address
