This application discloses a Bluetooth connection method, and relates to the field of short-range wireless communications technologies. The method includes: A terminal sends a service inquiry request to a Bluetooth device after the terminal and the Bluetooth device establish an asynchronous connectionless ACL link. The service inquiry request includes information about a service supported by the terminal. The Bluetooth device sends a service inquiry response to the terminal in response to the service inquiry request. The service inquiry response includes information about a service supported by the Bluetooth device. The terminal performs pairing with the Bluetooth device after the terminal receives the service inquiry response sent by the Bluetooth device. The terminal establishes a connection based on a first service to the Bluetooth device when both the terminal and the Bluetooth device support the first service. This reduces a period of time for establishing a Bluetooth service connection.

An Internet of Things data transmission method includes sending, by a terminal device, a first data request to a server, and continuously receiving, by the terminal device, N data packets from the server. The first data request instructs the server to continuously send a plurality of data packets. The first data request includes a quantity N of data packets, that the terminal device is capable of continuously receiving, and a time interval for sending two consecutive data packets, where N is an integer greater than 1. The N data packets include at least one non-confirmable Constrained Application Protocol (NON) data packet, a sending time interval between two consecutive data packets in the N data packets and the at least one NON data packet indicates that sending a receiving response from the terminal device to the server is unnecessary.

The invention relates to a method for preventing TCP SYN package flood attack, and belongs to the computer network security field. First, the firewall receives a client a TCP SYN connection request package, and responses, as an agent of the server, an acknowledgement of the TCP SYN connection request package with zero window size to the client. Then, the firewall records information about the TCP SYN connection request package and checks whether the connection request is legal. When the firewall has received a TCP SYN response package from the server, it returns an acknowledgement of said TCP SYN response package. At the same time, the firewall, as an agent of the server, sends an acknowledgement packet with nonzero window size to the client for initiating data transmission from the client. After that, data packets are transferred between the client and the server forwarded by the firewall as an agent. With the invention method, it can guarantee that protected servers in a computer network will not be destroyed by TCP SYN package flood attack.

An enclosure assembly for a portable electronic device according to a preferred embodiment of the present invention includes a cover (), a plurality of latching elements (), and a housing (). The cover has a plurality of hooks () at a lower end and a plurality of tabs () defining grooves () therein extending from sidewalls () thereof. Each latching element comprises a plurality of protrusions () and a detaching means (). The housing has a plurality of slots () at its sides and projections () at its lower end. Each projection defines a notch (). In assembly, each latching element is received in a slot of the housing, the protrusions engage with the tabs of the cover and the hooks of the cover are received in the notches of the housing. To disassemble, the consumer uses two pointed objects to push the detaching means of the latching elements towards the lower end of the housing, disengaging the protrusions from the tabs.
