Abstract: This application discloses a gateway configuration method and a gateway device, so as to resolve problems of a relatively heavy configuration workload, update inflexibility, and low configuration efficiency that exist when an OM entity is used to uniformly configure gateways in an LTE system. The method includes: configuring, by a control plane gateway, a parameter for a user plane gateway, and sending, by the control plane gateway, a configuration message to the user plane gateway, where the configuration message carries the configuration parameter configured by the control plane gateway for the user plane gateway. In this application, the control plane gateway configures the parameter for the user plane gateway, so that the control plane gateway implements configuration of the user plane gateway, and configuration flexibility and configuration efficiency are improved.

Abstract: A communication method includes determining, by a terminal side device in a mobile communications system, N random access preambles on N uplink bandwidth parts (BWPs) in a random access process, where N is an integer greater than or equal to 2, and sending, by the terminal side device, the N random access preambles to a network side device so that the terminal side device can perform random access on a plurality of uplink BWPs. In this method, the network side device or each terminal side device may subsequently perform random access on any one of the N uplink BWPs.

Abstract: The present invention relates to the field of mobile communications technologies, and in particular, to a gateway system, so as resolve a technical problem of a complex network structure caused due to that different network architectures need different gateways. The gateway system provided in the present invention separates a control plane from a forwarding plane. A gateway controller is configured to complete a control function, and may control respective generation of control information for data packets of multiple different protocol types. A gateway forwarding device is responsible for forwarding, and may be controlled by the gateway controller to receive and send data packets of various protocol types. In a multi-standard access architecture, only one or few such gateway systems may need to be accessed instead of accessing multiple different gateways, thereby simplifying a network topology structure, and facilitating network maintenance.
