Abstract: When obtaining a first Border Gateway Protocol (BGP) route, a first network device may directly send the first BGP route to a second network device without recursing the first BGP route. Alternatively, the first network device recurses the first BGP route. The first network device still sends the first BGP route to the second network device when the first BGP route fails to be recursed. That is, regardless of whether the first network device performs recursion or if the recursion fails, the first network device can forward the received first BGP route to the second network device.

Abstract: A dielectric lens, where the dielectric lens is a cylindrical lens or an ellipsoidal lens whose cross-sectional profile is a quasi-ellipse, and the dielectric lens is formed by piling a plurality of units. Dielectric constant distribution of the units in the dielectric lens enables a non-plane wave in a minor axis direction of the quasi-ellipse to be converted into a plane wave through the dielectric lens. The units of the dielectric lens are prepared through extrusion, injection, molding, computer numerical control (CNC) machining, or a three dimensional (3D) printing process technology, and the units may be assembled through gluing, welding, structural clamping, or a coupling printed through 3D printing. When the dielectric lens is applied to a multi-beam antenna, a system capacity of a communications system can be increased. In addition, a thickness of the lens is reduced using the multi-beam antenna.

Abstract: Embodiments of the present disclosure include methods for keeping in a CSFB network and an example user terminal, wherein when a first call of a 4G user fails to be set up, the user terminal keeps in a target network accessed by circuit switched fallback (CSFB). In this way, when the 4G user receives a call request message for the second time, the user terminal does not need to perform CSFB, thereby increasing a call setup success rate. One example method includes obtaining, by a user terminal, a first call request message. The user terminal performs CSFB according to the first call request message to access a target network. The user terminal determines whether a call setup message is received. If no call setup message is received, the user terminal camps on the target network.

Abstract: This application discloses a service level configuration methods and apparatuses, and belongs to the field of communications network technologies. According to an example method, a target service level used by a first forwarding node to forward a data flow is directly determined based on a transmission parameter of the data flow and service level information of the first forwarding node, and service level configuration is performed on the first forwarding node. Because a transmission parameter of the target service level of the first forwarding node and the transmission parameter of the data flow meet a first target condition, if the first target condition is a delay requirement required by a special service and the first forwarding node transmits the data flow by using the target service level, transmission of the data flow may meet the delay requirement required by the special service.
