Abstract: A communications terminal includes an antenna structure and a metallic frame that includes at least one slot. The antenna structure includes an NFC antenna and a non-NFC antenna. The NFC antenna includes an NFC radiator, a first filtering unit, and an NFC circuit, and the non-NFC antenna includes a non-NFC radiator, a second filtering unit, and a non-NFC circuit. The NFC radiator and the non-NFC radiator are formed by the metallic frame of the communications terminal, and the entire non-NFC radiator is in the NFC radiator. The NFC circuit is coupled to the NFC radiator by using the first filtering unit, the non-NFC circuit is coupled to the non-NFC radiator by using the second filtering unit, the first filtering unit is configured to filter out a non-NFC signal, and the second filtering unit is configured to filter out an NFC signal.

Abstract: A batch data query method and apparatus are provided. According to the method, multiple logical query plan trees corresponding to multiple query statements are obtained. The multiple logical query plan trees are divided into multiple query groups according to operators of each logical query plan tree. Logical query plan trees in each query group have the following relationship: an inter-query write-read dependency relationship, an operator overlap relationship, or an operand overlap relationship. Then, inter-query optimization is performed on the logical query plan trees in each query group, and multiple corresponding physical query plan trees are generated according to the multiple optimized logical query plan trees. Finally, physical queries are executed according to the multiple physical query plan trees, to obtain query results of the multiple query statements.

Abstract: A method includes: when performing information transmission with a first access point AP on a first frequency band, determining, whether the terminal equipment needs to establish a connection with a second AP, which is a second frequency band; determining, by the terminal equipment, whether the first AP and the second AP are corresponding to a same dual-band radio access device; sending, by the terminal equipment, a connection request to the second AP when maintaining a protocol layer connection with the first AP; and if establishing, by the terminal equipment, the connection with the second AP when the second AP send feedback.

Abstract: A batch data query method and apparatus are provided. A data query server determines symbol identifiers of operands in N query statements according to operators and the operands in the N query statements, where the symbol identifiers include version numbers of the operands; determines dependency among the N query statements according to the version numbers of the operands in the N query statements; and then, performs inter-query optimization on the N query statements according to the dependency among the N query statements and a preset optimization rule.

Abstract: The present invention provides a method for handover between access points, and terminal equipment. The method includes: when performing information transmission with a first access point AP on a first frequency band, determining whether the terminal equipment needs to establish a connection with a second AP which is a second frequency band; determining, by the terminal equipment, whether the first AP and the second AP are corresponding to a same dual-band radio access device; sending, by the terminal equipment, a connection request to the second AP when maintaining a protocol layer connection with the first AP; and establishing, by the terminal equipment, the connection with the second AP when the second AP send feedback. In the method, duration required by a process of handover between access points can be reduced, and a user is made not perceive the handover process, thereby improving user experience.
