20120020344 | WIRELESS MACRO CELL OVERLAY - Overlaying a Wireless Macro Cell architecture on a Micro Cell network. WLAN MAC Address Translation (WMAT) is used to translate BSSIDs from the BSSID used to initialize a radio in an access node and identify communications between the radio in the access node and a controller, and the BSSID used over the air for Macro Cell operation. WMAT is used for transmit operations, translating the BSSID of outgoing packets to the Macro Cell BSSID prior to wireless transmission. On the receive side, packets undergo WMAT and transmission to the controller if the STN MAC address of the sender is in an ACK table associated with the radio, or the packet is one of a predetermined type. The ACK table is managed by transmit operations, and by control commands from the controller. | 2012-01-26 |
20120020345 | METHOD FOR IMPLEMENTING LIMITED POLICY AND CHARGING CONTROL AND SYSTEM THEREOF - The present invention provides a method and system for implementing limited policy and charging control. The method comprises a PCRF determining whether a visited network where a UE roams supports PCC, and sending a message containing an identifier indicating the limited policy and charging control deployment to an AF. After receiving the message containing the identifier, the AF performs no subscription of the event trigger and/or cancels the subscription of the event trigger based on the identifier. Using the method and system in accordance with the present invention, the AF can be notified more conveniently and accurately of the current policy and charging control deployment situation when the limited policy and charging control is implemented (i.e., when the visited network does not support the PCC). Moreover, the AF may perform the corresponding operations according to the current policy and charging control deployment situation, thereby saving system resources. | 2012-01-26 |
