    Abstract: A network device may receive, from a sending device, a message in a first messaging format en route to user equipment. The first messaging format may correspond to one of a 3GPP cellular network standard or a 3GPP2 cellular network standard. The network device may determine whether the user equipment is associated with the first messaging format or with a second messaging format. The second messaging format may correspond to one of the 3GPP cellular network standard or the 3GPP2 cellular network standard. The first messaging format and the second messaging format may be associated with different cellular network standards. The device may selectively provide the message in the first messaging format or the second messaging format based on whether the user equipment is associated with the first messaging format or the second messaging format. The device may transmit an acknowledgment message based on the first messaging format.

    Abstract: A calling device may obtain a first calling security parameter by registering with a network and obtain a second calling security parameter in response to causing an application authentication architecture of the network to verify that that the calling device is authorized to access a network service corresponding to a communication application stored by the calling device. The calling device may communicate the first and second calling security parameters to a called device and receive first and second called security parameters from the called device in response to communicating the first and second calling security parameters. The calling device may generate a security key based on the first calling security parameter, the second calling security parameter, first called security parameter, and the second called security parameter, and use the security key to encrypt or decrypt communication between the calling device and the called device.

    Abstract: Systems described herein use a group packet data network (PDN) to support communications from machine-type communications (MTC) devices on wireless networks. The systems assign a MTC device to a group with a group identifier, the group associating the MTC device, and other MTC devices, with a particular customer network; receive an attach request from the MTC device; retrieve, based on the attach request, the group identifier for the MTC device; configure a bearer path between the MTC device and the particular customer network, the bearer path including a group PDN that transports data packets from the MTC device, and the other MTC devices, between a serving gateway (SGW) and a PDN gateway (PGW); and send data packets from the MTC device over the group PDN.

    Abstract: A first device associated with an evolved packet core network receives a first update request from a second device associated with the evolved packet core network. The first update request is associated with a communication session previously provided between the first device and the second device, and the first update request is generated based on a voice/video request. The first device generates an update answer in response to the first update request, where the update answer includes a code requesting that the communication session be restored between the first device and the second device. The first device receives, based on the code, a second update request from the second device, where the second update request includes session information associated with the communication session. The first device restores, based on the session information, the communication session between the first device and the second device to create a restored communication session.
