Changes of forward-link and reverse-link serving access points

摘要

In a communication system in which a mobile station accessing the main network via a plurality of base stations, the mobile station can freely select any of the base stations as a forward link (FL) serving station. In addition, the mobile station can also freely select another or the same base station as a reverse link (RL) serving station. The mobile station has stored in its memory a plurality of routes corresponding to the plurality of base stations, with each route dedicatedly assigned to a particular base station. During handoff of one base station to another as either the FL or the RL serving station, exchanged data packets are processed in the respective routes of the base stations involved.

1. A method of communications, comprising:
providing assessment of a set of communication conditions; allocating a forward communication link to a first communication entity based on said assessment; allocating a reverse communication link to a second communication entity based on said assessment; maintaining a route with one of the first and second communication entities upon initiation of a handoff from the one of the first and second communication entities to a third communication entity, wherein the route is a route through which Internet protocol (IP) packets are tunneled from the one of the first and second communication entities via the third communication entity; providing another route for communications with the other of the first and second communication entities; initiating the handoff from the one of the first and second communication entities to the third communication entity while maintaining communication with the other of the first and second communication entities; processing a first partial IP data packet of a full IP data packet from the one of the first and second communication entities via the third communication entity using the route; and processing a second partial IP data packet of the full IP data packet from the other of the first and second communication entities using the another route.
