Wireless communication system and routing method for packet switching service, femto AP using the routing method
First Claim
1. A wireless communication system, comprising:
- a mobile core network, for providing a plurality of services;
a broadband IP network, connected to the mobile core network and a packet switched service supply end;
a Femto access point (FAP), connected to the broadband IP network, wherein the FAP has a session management function; and
a user equipment (UE), connected to the FAP through a wireless approach, so as to connect the broadband IP network through the FAP, and establish a connection channel with the mobile core network to obtain at least one of the services,wherein when the UE performs a packet switched service request, an activate packet data protocol (PDP) context request message is sent to the FAP by the UE, the FAP evaluates the PDP context request message and determines whether a packet switched service accessed by the UE can be transmitted without routing through the mobile core network, if yes, the FAP generates and directly replies an activate PDP context accept message to the UE, wherein the activate PDP context accept message comprises a setting address provided by the FAP, and the UE sends a packet switching data to the FAP according to the setting address in order to obtain the packet switched service, and the FAP directly conduct the packet switched service with the packet switched service supply end through the broadband IP network.

Abstract
A wireless communication system, a routing method for a packet switched service, and a Femto AP (FAP) using the routing method are provided. The wireless communication system may include a core network, a broadband IP network, a FAP and at least a user equipment (UE). The UE connects the core network through the FAP and the broadband IP network. The routing method is as follows. The FAP may evaluate a request of the packet switched service sent by the UE, and may reply an accept message to the UE. The accept message may include a FAP address. The UE may use the FAP address to send a packet switching data to the FAP in order to obtain the packet switched service. The FAP may directly conduct the packet switched service with a packet switched service supply end through the broadband IP network without routing through the core network.
