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.

Messaging format conversion for a cellular network

A method may include receiving, at a serving call session control function (S-CSCF) device, from a home subscriber server (HSS), a subscriber profile that includes a first subscription state associated with a user device. The first subscription state is one of a plurality of subscription states in addition to barred and not barred. The method includes routing messages to at least one of a plurality of application server devices based on at least one initial filter criteria (iFC) associated with the first subscription state. The method also includes receiving, at the S-CSCF device and from the HSS, a subscription state change to a second subscription state from the HSS, wherein the second subscription state is one of the plurality of subscription states. The method further includes identifying at least one iFC associated with the second subscription state, and routing messages to at least one of the plurality of application servers based on the at least one iFC associated with the second subscription state.

Service support for suspended and inactive subscribers

A method and system are provided for blocking data packets that are not desired or capable of being received. One or more data packets are received from a data server. The data packets that are addressed to a wireless device are transmitted via a gateway server. The error messages generated by either the wireless device or the gateway server are forwarded to the data server and their number also counted. When the number of error messages meets a predetermined criterion, additional data packets from the data server that are addressed to the wireless device are blocked, for example, preventing tolling the user account of the wireless device for data packets sent by the data server when the device is not available or the user no longer wants to receive the data.

Dynamic flow management at a firewall based on error messages

A mobile communication device registers for data communication through a mobile communication network with a packet-based network. The device may or may not have a mobile device number, and registers using a fully-qualified-domain-name (FQDN) uniquely identifying the device in a domain-name-system (DNS) of the packet-based network. A packet-data-network gateway assigns a packet-based address for the device, and generates a request for registering the address with the FQDN in a DNS server. Alternatively, the device generates the packet-based address based on a received portion of the address, retrieves the FQDN from an identity module, and sends a DNS-Update message to the DNS server including the address and FQDN. Again alternatively, a DNS server receives an encrypted DNS update message including a FQDN and a packet-based address, and decrypts the message prior to registering the address and FQDN in a DNS database.

Methods and systems for registering a packet-based address for a mobile device using a fully-qualified domain name (FQDN) for the device in a mobile communication network

Systems and methods for handling an OPEN CHANNEL command from a universal integrated circuit card (UICC) of a mobile device are disclosed. In some implementations, a mobile device hosting a UICC receives, from the UICC, an initiation of an OPEN CHANNEL command with a uniform resource locator (URL) of a subscriber identity module over the air (SIMOTA) server. The mobile device signals for attempting to resolve the URL to an Internet Protocol (IP) address. Upon successfully resolving the URL to the IP address, the mobile device obtains the IP address associated with the SIMOTA server, connects to the SIMOTA server using the IP address, and returns a successful TERMINAL RESPONSE to the UICC. Upon failing to resolve the URL to the IP address, the mobile device returns an unsuccessful TERMINAL RESPONSE to the UICC.
