Systems and methods for assigning unique network identifiers in a packet-switched wired network and methods for communicating with a network device in a packet-switched wired network are provided. A request for a unique network identifier for a network device is received. A socket-based unique network identifier, including an IP address and one or more ports, is assigned to the network device. The unique network identifier is created by combining an IP address and one or more ports. This allows multiple unique network identifiers to be created from a single IP address, where each unique network identifier consists of the same IP address combined with a different group of one or more ports.

Methods and computer-readable media are provided to enable an Internet protocol (IP) data session to be established between a mobile device and a telecommunications network. To establish an IP data session, it may be determined, prior to authenticating the device, whether the device is authorized to communicate via IPv4, IPv6, or both. A mobile device may be capable of communicating via both IPv4 and IPv6, such as a dual-stack device, but the device may only be authorized for either IPv4 or IPv6. A request to establish the IP data session may first be received from a mobile device, and an IP version with which the mobile device is authorized to communicate may then be determined by querying a customer-profile database. This authorization information may be communicated to an authentication component that authenticates the devices, and subsequently, an IP data session is initiated.

Computer systems, computer-readable media, and computerized methods for resolving fractional IP addresses using domain name system (DNS)-enabled devices are provided. The system includes a local DNS server that accesses a correlation table, which maintains a mapping between fractional IP addresses and domain names. The fractional IP addresses each represent an IPv4 address paired with a respective value of an IP version field. The system also includes a client device that is capable of transmitting to the local DNS server a request message, which includes a destination name of a device targeted by the client device. Upon receiving the request message, the local DNS server compares the destination name against the correlation table. When a match is discovered within the domain names populated within the correlation table, the local DNS server identifies and transmits to the client device a fractional IP address mapped to the matching domain name.

Systems and methods for assigning unique network identifiers in a packet-switched wireless network and methods for communicating with a wireless device in a packet-switched wireless network are provided. A request for a unique network identifier for a wireless device is received. A socket-based unique network identifier, including an IP address and one or more ports, is assigned to the wireless device. The unique network identifier is created by combining an IP address and one or more ports. This allows multiple unique network identifiers to be created from a single IP address, where each unique network identifier consists of the same IP address combined with a different group of one or more ports.

Computer systems, computer-readable media, and computerized methods for determining a media access (MAC) address that corresponds with a network identifier in a wireless or wired network are provided. A dynamic host configuration protocol (DHCP) server is employed to allocate a set of fractional IP addresses that include a common IPv4 address paired with a value of an IP version field, where none of the values overlap. When assigned to a client device, the fractional IP address uniquely identifies the client device within the network. A host device within the network is configured to broadcast an address resolution protocol (ARP) request to other devices within the network, such as the DHCP server, where the ARP request includes a fractional IP address associated with intended recipient(s) of communications from the host device. In response to the ARP request, the appropriate device or DHCP server returns a MAC address of the intended recipient(s).

Communication to a target device using IP is provided. An IPv6 address is registered. An AAAA-record DNS lookup is performed and an A-record DNS lookup is performed, both using the IPv6 network. A response related to the AAAA-record DNS lookup is received and a response to the A-record DNS lookup is received. If a valid IPv6 address is contained in the AAAA-record response, communication uses IPv6. If no valid IPv6 address is contained in the AAAA-record response, an IPv4 address is registered and communication uses IPv4.

Methods are described for communicating a reregistration timer to a mobile device. A request is received from a mobile device to establish an IP communication session so that the mobile device is able to communicate by way of a wireless communication network. An allocation component assigns an IP address to the mobile device, in addition to a lifetime value that indicates a length of time after which the IP communication session expires. A threshold value is determined, which is a length of time prior to the expiration of the IP communication session when the session is to be renewed to avoid expiration. Based on the lifetime value and the threshold value, an existing lifetime timer is set and communicated to the mobile device, along with the assigned IP address.

Methods are described for managing the allocation of IPv6 addresses to mobile devices. More specifically, the network portions of IPv6 addresses are dynamically allocated to mobile devices by a home agent. In one embodiment, a request is received to allocate a network portion of an IPv6 address. It is determined whether a network portion is stored in a database in association with the mobile device. If so, that network portion is allocated to the mobile device so that the mobile device can establish a communication session. If not, the home agent is asked to allocate a network portion that is currently available.
摘要:
Methods are provided for negotiating a static IPv6 address with a mobile device such that the mobile device can use the address to establish a communications session. Initially, a static IPv6 address that the mobile device is proposing to use is received. It is determined that the static IPv6 address is stored in a database in association with the mobile device. As the static IPv6 address is stored, the mobile device is allowed to establish a communications session using the proposed IPv6 address.
