    Abstract: Embodiments of the present invention provide a congestion/overload control method and apparatus. The method includes: learning, by a gateway device, information about network access time of a User Equipment (UE) or UE group; and rejecting or discarding, by the gateway device, session management request messages of the UE or UEs in the UE group beyond the network access time of the UE or UE group; or discarding, by the gateway device, data of the UE or the UEs in the UE group beyond the network access time of the UE or UE group. Embodiments of the present invention can perform congestion/overload control differentially on the UE or UEs in the group, implement congestion/overload control on the gateway device, avoid congestion/overload caused by a large number of UEs on the gateway device, and improve the efficiency of congestion/overload control.

    Abstract: A data processing method is provided for forwarding data in the case of handover between heterogeneous networks. The data processing method includes: when a user equipment (UE) is handed over from an originating network to a target network, receiving, by the originating network, a data forwarding address obtained by the target network; creating a data forwarding tunnel between an originating network gateway and a target network gateway according to the data forwarding address; and forwarding data to the target network through the data forwarding tunnel. A data processing device is also provided. The lossless data processing solution can overcome the problem of data loss in the case of handover between heterogeneous networks in the existing technology, reduces the time of user service interruption and enhances the user experience.
