Abstract
A method is provided in one example embodiment and includes invoking a mobile access gateway function based on an end user requesting an Internet Protocol (IP) address in a wireless or a wireline network. The invocation is selective such that the mobile access gateway function is invoked if the end user requires IP mobility services. The method also includes communicating with a gateway in order to obtain the IP address. The mobile access gateway function is coupled to a network element that receives packets for a communications flow from the end user that can conduct the flow through the wireless network and through the wireline network.
Claims21
A method for reducing Internet Protocol (IP) mobility overhead, comprising:
- receiving option information from a Dynamic Host Configuration Protocol (DHCP) server as part of an IP address assignment procedure, the option information identifying IP address ranges, subnets, and next-hop IP gateways for each service to which a device has access;
- deciding whether IP mobility services are needed based on the option information;
- invoking IP mobility services in a wireline access network for the device requesting an IP address only if IP mobility services are needed;
- obtaining the IP address for the device based on the option information;
- and
- conducting a communication flow associated with the device between a wireless network and the wireline access network.
An apparatus for reducing Internet Protocol (IP) mobility overhead, comprising:
- a memory for storing information;
- and
- a processor operable to execute instructions associated with the information;
- a mobile access gateway function that when executed by the at least one processor is configured to:
- receive option information from a Dynamic Host Configuration Protocol (DHCP) server as part of an IP address assignment procedure, the option information identifying IP address ranges, subnets, and next-hop IP gateways for each service to which a device has access;
- decide whether IP mobility services are needed based on the option information;
- invoke IP mobility services in a wireline access network for the device requesting an IP address only if IP mobility services are needed;
- obtaining the IP address for the device based on the option information;
- and
- conduct a communication flow associated with the device between a wireless network and the wireline access network.
One or more non-transitory tangible media comprising logic for reducing Internet Protocol (IP) mobility overhead for execution and when executed by a processor operable to:
- receive option information from a Dynamic Host Configuration Protocol (DHCP) server as part of an IP address assignment procedure, the option information identifying IP address ranges, subnets, and next-hop IP gateways for each service to which a device has access;
- decide whether IP mobility services are needed based on the option information;
- invoke IP mobility services in a wireline access network for the device requesting an IP address only if IP mobility services are needed;
- obtaining the IP address for the device based on the option information;
- and
- conduct a communication flow associated with the device between a wireless network and the wireline access network.
A system for reducing Internet Protocol (IP) mobility overhead, comprising:
- means for receiving option information from a Dynamic Host Configuration Protocol (DHCP) server as part of an IP address assignment procedure, the option information identifying IP address ranges, subnets, and next-hop IP gateways for each service to which a device has access;
- means for deciding whether IP mobility services are needed based on the option information;
- means for invoking IP mobility services in a wireline access network for the device requesting an IP address only if IP mobility services are needed;
- means for obtaining the IP address for the device based on the option information;
- and
- means for conducting a communication flow associated with the device between a wireless network and the wireline access network.
