Abstract: A method includes obtaining a first count value of a first protocol data unit, delivering a service data unit corresponding to a second value set in a first value set to an upper layer protocol stack, and deleting a fourth value set from a third value set when the first count value matches a second count value, where the first value set includes a count value corresponding to a protocol data unit, delivered in-order, in a receiving buffer of a wireless device, the third value set includes a count value corresponding to a protocol data unit that has been delivered by the wireless device to the upper layer protocol stack out-of-order, and a fifth value set including the second value set and the fourth value set is a continuous count value section for which counting starts from the first count value.

Abstract: Embodiments of the present invention provide a resource switching method, an apparatus, and a system. The method includes: receiving, by a first device, a first resource switching message sent by a second device, where the first device and the second device belong to a same service group, the first resource switching message includes first resource information, and the first resource information is used to indicate a first resource satisfying a resource switching requirement of the second device; determining, by the first device, a second resource in the first resource, where the second resource is a resource satisfying a resource switching requirement of the first device; and sending, by the first device, a second resource switching message, where the second resource switching message includes second resource information, and the second resource information is used to indicate the second resource.

Abstract: The present invention provides a security authentication method, a configuration method, and a related device. A first terminal receives a public key for signature of a configuration device sent by the configuration device. The first terminal receives second signature information and second type information. The first terminal determines, according to at least the second type information and the second signature information, that the first terminal is to generate key information. In this way, the first terminal establishes a security connection between the first terminal and the second terminal. This effectively prevents a terminal from tampering with its role, and therefore effectively prevents a terminal from establishing a connection to an attacker terminal with a changed role, thereby further preventing the attacker terminal from obtaining information of the terminal, to effectively ensure security of the terminal.
