Abstract: Soft information for achieving interference cancellation in downlink transmissions can be communicated over device-to-device (D2D) links, thereby allowing paired user equipments (UEs) to receive downlink transmissions over the same radio resources. More specifically, paired UEs that receive transmissions over the same time-frequency resources may exchange soft or hard information over D2D links in order to facilitate interference cancellation. The D2D links may be unidirectional or bidirectional, and may be established over in-band or out-of-band resources. Paired UEs may be in the same or different cells, and may receive their respective transmissions from the same or different transmit point. UEs may be paired with one another based on various criteria, e.g., interference cancellation capabilities, scheduling metrics, etc.

Abstract: The present invention relates to a method, a system, a gateway, and a server for canceling redirection. When balances of a user are insufficient, a gateway (GW) receives a redirection policy delivered by a policy and charging rules function (PCRF) and redirects the user to a recharging page of a server; after recharging is finished, the server sends a recharging success packet to the GW, and the GW instructs the PCRF to cancel the redirection policy. In this way, after the recharging succeeds, the server directly sends the recharging success packet to the GW, and the GW can immediately instruct the PCRF to cancel the redirection policy after receiving the packet. Therefore, no delay problem of a billing system exists, thereby avoiding that the user is repeatedly redirected to the recharging page of the server during a delay time and enhancing user experience.
