Abstract:
1. A method of assigning a socket-based unique network identifier in a packet-switched wireless network, comprising: grouping unassigned ports of IP address into at least two groups; receiving a request for a first unique network identifier for a first wireless device having a first network access identifier; assigning the first unique network identifier to the first wireless device, wherein the first unique network identifier includes an IP address and one or more ports; receiving a request for a second unique network identifier for a second wireless device having a second network access identifier; assigning the second unique network identifier to the second wireless device, wherein the first unique network identifier is created by combining the IP address and one or more ports from a first port group, the second unique network identifier is created by combining the IP address and one or more ports from a different port group, and the second unique network identifier includes the same IP address assigned to the first wireless device and one or more different ports that are not assigned to the first wireless device; and updating a binding table that stores the first network access identifier and the second network access identifier and the corresponding first unique network identifier and the second unique network identifier, wherein the network access identifiers and the group of ports allow a mobility agent to route messages to the appropriate wireless device.
