Method for sending packet data, base station, and mobile station
First Claim
1. A method of sending packet data for a mobile station (MS) in a cell, the method comprising:
- maintaining, by the MS, information of cluster head MSs including resource information of the cluster head MSs and utilization information of respective cells in which the cluster head MSs are located;
receiving, by the MS, packet data from a source MS, wherein the packet data comprises an identity of a destination MS;
searching by the MS for a path to the destination MS in a routing cache table;
if the path is not found, forwarding the packet data by;
selecting a cluster head MS from among the cluster head MSs according to the resource information of the cluster head MSs maintained by the MS, the maintained resource information of the selected cluster head MS including resource information of a cell interface of the cluster head MS, a path loss of a link between a cell interface of the MS and the cluster head MS, resource information of an adhoc interface of the cluster head MS and a path loss of a link between an adhoc interface of the MS and the cluster head MS, and according to the utilization information of the cell in which the cluster head MS is located and utilization of a the cell in which the MS is located;
sending a cluster head MS request to the selected cluster head MS, wherein the cluster head MS request comprises the identity of the destination MS; and
sending the packet data to the selected cluster head MS if a cluster head MS response sent by the selected cluster head MS is received by the MS.

Abstract
A method for sending packet data is provided, which includes the following steps. Packet data from a source mobile station (MS) is received. The packet data includes an identity of a destination MS. A routing cache table is searched for a path to the destination MS. An interface is selected if the path to the destination MS is found. The packet data is forwarded through the selected interface according to the found path. Other two methods for sending packet data corresponding to the method for sending packet data as well as an MS and a base station (BS) corresponding to the method for sending packet data are provided. Therefore, link processing can be performed at the MS.
