Abstract: Embodiments include originating and terminating a short message service (SMS) message using an IP network. Delivery of an SMS message is attempted on a first network a first predetermined number of times according to a first predetermined time schedule. Delivery of the SMS message on a second network is attempted after a failure to deliver the SMS message on the first network. Reattempted delivery of the SMS message on the first network is followed by reattempted delivery of the SMS message on the second network, according to a second predetermined time schedule. Embodiments also include monitoring registration of a recipient of the SMS message, receiving a new registration, and attempting delivery of the SMS message on the network associated with the new registration.

Abstract: Disclosed herein are system, method, and computer program product embodiments for an access gateway control function server to convert between network-based call signaling messages and session initiation protocol messages. An embodiment operates by receiving in a first access gateway control function server, a first session initiation protocol (SIP) message sent from a first device and converting the SIP message in the first access gateway control function server to a first network-based call signaling (NCS) message to be received by a second device.

Abstract: Methods and systems for multimedia messaging service (MMS) authentication over IP networks are disclosed. An access identifier records message corresponding to a user by a multimedia messaging service center (MMSC) forwarded by a server is received. Data from the access identifier records message including a mobile directory number, a framed IP address, access network information and a session ID is extracted and stored in a cache accessible to the MMSC. Network IP authentication is executed to determine that the user has a valid IP address. Client IP authentication of the user is executed to determine that the valid IP address is stored in the cache. A correspondence between the valid IP address and a mobile directory number of the user is determined. The user is authenticated for MMS over the IP network based on the correspondence.
