A transmit module transmits the IP connectivity indicator to a remote network device before at least one of detachment of the SRD and deactivation of a bearer corresponding to a first session and a tunnel between the SRD and the remote network device. A control module facilitates the detachment of the SRD and deactivation of the bearer while maintaining IP connectivity. The IP connectivity corresponding to at least one of attachment of the SRD and activation of a second session of the SRD based on the IP connectivity indicator. | 12-25-2008 |
20090022124 | SYSTEM AND METHOD FOR ALLOCATING AN ANCHORING POINT FOR A MOBILE TERMINAL - A mobile terminal includes an Internet Protocol (IP) address module that requests and receives a first IP address from a home anchoring point within a home network. The first IP address is an address of the home anchoring point. The system also includes a packet module that exchanges packets with the home anchoring point via a first attachment point. The packets include the first IP address. | 01-22-2009 |
20090022126 | MULTIPLE PACKET DATA NETWORK SUPPORT OVER TRUSTED ACCESS - A media access gateway comprises a wireless network interface, an authorization module, a filter information module, and a proxy mobility agent module. The wireless network interface selectively establishes a wireless link with a first interface of a wireless terminal that has a plurality of wireless interfaces. The authorization module determines a home agent corresponding to the wireless terminal. The filter information module receives filter information from one of the wireless terminal and a server and generates output filter information. The proxy mobility agent module transmits a binding update to the home agent. The binding update includes the output filter information. | 01-22-2009 |
20090034534 | SYSTEM AND METHOD FOR ESTABLISHING AND MANAGING MULTIMEDIA SESSIONS BETWEEN TERMINALS - A source communication terminal includes a communication module that initiates a first communication with a first remote terminal via first Internet protocol (IP) multimedia subsystems (IMS) of a first IP network. The first communication includes X media components. The source communication terminal also includes a media transfer module that transfers Y of the X media components to a first target terminal of Z target terminals during the first communication. The source communication terminal also includes a control module that provides an indication to the first IMS of a control model for the first communication. The control model is implemented after the Y media components have been transferred to the first target terminal. The control model identifies at least one of the source communication terminal and the first target terminal that controls IMS signalling for the first communication. X, Y and Z are integers greater than or equal to 1, and Y is less than or equal to X. | 02-05-2009 |
20090040964 | DYNAMIC INTERNET PROTOCOL ADDRESSING SOLUTIONS WITH NETWORK-BASED MOBILITY - A media access gateway comprises a wireless network interface, an address assignment module, and a proxy mobility agent module. The wireless network interface establishes a wireless link with a wireless terminal. The address assignment module receives an address request message, which includes a mobility signal from the wireless terminal. The proxy mobility agent module selectively transmits a proxy binding update to a local mobility anchor and receives a proxy binding acknowledgement from the local mobility anchor. The address assignment module selectively transmits an address assignment message to the wireless terminal when the mobility signal indicates proxy mobility. The address assignment message is based on address information in the proxy binding acknowledgement. | 02-12-2009 |
20090043902 | PACKET DATA NETWORK CONNECTIVITY DOMAIN SELECTION AND BEARER SETUP - A network device includes a packet data name (PDN) description generator that generates a PDN descriptor. The PDN descriptor includes at least one of a PDN identifier and a PDN gateway identifier. A transmit module transmits the PDN descriptor to a remote device before bearer setup of the network device by a remote network. A receive module receives a reply signal from the remote network that indicates the bearer setup based on the PDN descriptor. A control module communicates with a PDN gateway based on the reply signal. | 02-12-2009 |
20090109986 | SYSTEM AND METHOD FOR RESELECTION OF A PACKET DATA NETWORK GATEWAY WHEN ESTABLISHING CONNECTIVITY - A network control module includes an access module that determines whether a first packet data network gateway communicating with a first packet data network also communicates with a second packet data network. The network control module also includes a selection control module in communication with a mobile wireless terminal. The mobile wireless terminal attempts to access the second packet data network by establishing a connection with a second packet data network gateway that communicates with the second packet data network. In response to the access module determining that the first packet data network gateway also communicates with the second packet data network, the selection control module commands the mobile wireless terminal to access the second packet data network through the first packet data network gateway. | 04-30-2009 |
20120230277 | IP ADDRESS ALLOCATION IN EVOLVED WIRELESS NETWORKS - A network includes a database configured to store subscriber data associated with a wireless terminal, wherein the subscriber data indicates whether the wireless terminal requires allocation of an IP address during attachment of the wireless terminal to the network. The network module receives, from the wireless terminal, a request to attach to the network. In response to receiving the request, the network module retrieves the subscriber data stored in the database and selectively allocates an IP address to the wireless terminal based on whether the subscriber data stored in the database indicates that the wireless terminal requires allocation of an IP address during attachment of the wireless terminal to the network. | 09-13-2012 |
20140136732 | METHOD AND APPARATUS FOR WIRELESS DEVICE WITH MULTIPLE WIRELESS INTERFACES USING PROXY MOBILITY - A wireless device includes first and second wireless network interfaces, first and second address determination modules, and a mobility control module. The first interface establishes layer two connectivity with a first media access gateway. The first address determination module assigns a first address to the first interface in response to a first address assignment message received from the first media access gateway. The second interface establishes layer two connectivity with a second media access gateway in preparation for a handoff from the first media access gateway to the second media access gateway. The second interface transmits an address request message, indicating a desire for the first address to be assigned to the second interface, to the second media access gateway. The second address determination module assigns a second address to the second interface in response to a second address assignment message received from the second media access gateway. | 05-15-2014 |
