  • Patent number: 8428050
    Abstract: Embodiments of the present invention disclose a radio communication system and a radio access method. In accordance with the embodiments of the present invention, an AP with a PDP forward function unit forwards service traffic accessing an AS to a Packet Radio Service Gateway Support Node, and sends Internet service traffic to the Packet Radio Service Gateway Support Node or directly sends the Internet service data to the Internet via a configured forwarding interface according to the service property of the service traffic. Embodiments of the present invention further disclose an Access Point and a gateway. Therefore, the load of network elements of a mobile network is reduced; meanwhile, the control and the management of the high increment value services by operators can be guaranteed. The investment of the CS network can be protected by the gateway as a concentrator of Access Points and a forwarding node of CS services in the embodiments of the present invention.

  • Publication number: 20080205343
    Abstract: A method for allocating an SFID in a WiMAX network including an ASN and a CSN may include: establishing, by the CSN a service flow in response to a service flow creation request from an MSS, and sending the service flow to the ASN; and allocating, by the ASN, a value that currently is not used by the MSS as an SFID of the service flow requested by the MSS. A system for allocating an SFID in a WiMAX network is also provided. According to the method and system for allocating an SFID in a WiMAX network, after an MSS performs a handover, it is not necessary to notify a function module generating an SFID to release the SFID, thereby simplifying the SFID management.
