Abstract
A method for IP address allocation is presented. In one embodiment, the method includes receiving DHCP (Dynamic Host Configuration Protocol) information by a driver module operable on a mobile station prior to the mobile station sending a DHCP discovery message. The method includes storing, by the driver module, the DHCP information and redirecting the DHCP discovery message from an operating system DHCP process to the driver module. The method also includes performing DHCP hand-shaking in response to the DHCP discovery message.
Claims16
A method for a wireless communication network comprising:
- receiving, by a driver module on a mobile station, DHCP (Dynamic Host Configuration Protocol) information generated by a remote DHCP gateway and transmitted to the mobile station via a base station prior to the mobile station sending a DHCP discovery message;
- storing, by a driver module, the DHCP information;
- redirecting the DHCP discovery message from an operating system DHCP process to the driver module;
- performing DHCP hand-shaking in response to the DHCP discovery message, the driver module to intercept Internet Protocol (IP) configuration received from the wireless communication network to obtain an IP address instead of the operating system DHCP process and the driver module to receive the IP configuration from the wireless communication network during a registration phase of initial network entry via a registration response (REG-RSP) media access control (MAC) management message;
- wherein said performing DHCP hand-shaking comprises generating, by the driver module, a response to the DHCP discovery message without sending out a request to the remote DHCP gateway, communicating the DHCP information to the operating system DHCP process, and communicating a DHCP acknowledgment to the operating system DHCP process;
- and
- sending the IP configuration to the operating system DHCP process to allow the operating system to communicate with the wireless communication network using the IP address obtained by the driver module.

A method for a wireless communication network comprising:
- generating by an ASN (access service network), in response to network entry associated with a mobile station, DHCP (Dynamic Host Configuration Protocol) information without receiving a DHCP discovery message from the mobile station;
- and
- propagating the DCHP information to the mobile station via a first base station;
- the mobile station to receive the DHCP information from the first base station network during an initial service flow setup via a dynamic service addition response (DSA-RSP) media access control (MAC) management message or after initial entry is completed and initial service flow is established via a dynamic service change response (DSC-RSP) media access control (MAC) management message;
- the ASN comprises a gateway to allocate a DHCP IP to the mobile station, and one or more base stations including the first base station to communicate with the mobile station and the gateway;
- and further comprising
- sending, by the gateway in conjunction with a MAC negotiation message, the DHCP information to at least one of the base stations, and
- propagating, by the at least one base station in conjunction with a registration message, the DHCP information to the mobile station.

A network system comprising:
- a gateway to manage and to allocate IP addresses;
- and
- a base station to communicate with the gateway and to communicate wirelessly with a mobile station, the gateway to generate, in response to network entry by the mobile station, DHCP (Dynamic Host Configuration Protocol) information prior to receiving a DHCP message by the mobile station;
- the mobile station to receive the DHCP information from the base station network during an initial service flow setup via a dynamic service addition response (DSA-RSP) media access control (MAC) management message or after initial entry is completed and ISF is established via a dynamic service change response (DSC-RSP) media access control (MAC) management message;
- wherein the DHCP information is to be redirected and processed by a driver module rather than an operating system DHCP process;
- the gateway to send in conjunction with a MAC negotiation message the DHCP information to the base stations, and
- the base station to propagate in conjunction with a registration message the DHCP information to the mobile station.
