A user equipment (UE) is configured for wireless communication. The UE is configured to receive a first data unit set in a first protocol entity. The first protocol entity is configured as a non-signaling radio bearer. The UE is configured to start a timer in response to receiving a first data unit. The first data unit is a data unit in the first data unit set. The UE is configured to generate a second data unit set based on the first data unit in the first data unit set. The UE is configured to send, in response to determining that the timer is expired, an indication to a second protocol entity. The indication is an indication to discard the second data unit set. A protocol layer in which the first protocol entity is located is above a protocol layer in which the second protocol entity is located.

This invention discloses a minimal recursive delegated communication method and system, belonging to the field of computer network communication. The system contains only two protocol primitives, `register` and `push`, and achieves complete dynamic discovery and task delegation functions through delegated interaction between gateway entities and protocol entities. The gateway entity is deconstructed into three protocol entities: server, brain, and agent. It supports topology reversal where the gateway itself is employed by a higher-level gateway as a protocol entity, achieving infinite recursion and indistinguishability of the delegate chain. The method employs a three-layer abstraction system (L0 / L1 / L2) to separate protocol specifications, extension mechanisms, and application semantics, allowing for the emergence of organizational forms such as bureaucracy and market mechanisms through replaceable employment decision rules. This invention demonstrates the minimal completeness of delegated networks and is applicable to scenarios such as AI multi-agent collaboration, IoT device management, and social organization simulation.

This invention discloses a method for monitoring the status of high-voltage outgoing line switchgear based on 5G wireless communication. The method is executed by a first protocol entity of a mobile terminal and includes: receiving a data unit; parsing the data unit to obtain a first data sub-unit and a second data sub-unit; determining a second protocol entity instance corresponding to a first channel identifier; determining a first delivery priority of the first data sub-unit and a second delivery priority of the second data sub-unit based on priority adjustment conditions; and delivering the first data sub-unit and the second data sub-unit to the second protocol entity instance based on the first delivery priority and the second delivery priority. This invention can achieve priority delivery of alarm-type sub-data in scenarios with the same channel identifier and the same second protocol entity instance, reducing the latency of abnormal information processing and improving the real-time performance and reliability of high-voltage outgoing line switchgear status monitoring.

This invention provides a network protocol vulnerability detection method and system based on message sequence attribution optimization, addressing the problems of existing gray-box fuzzing methods for network protocols in three aspects: message sequence attribution strategy, message sequence evaluation and selection, and selection of mutation point locations in message sequences. The method includes: acquiring the target code of the protocol under test; using the protocol under test for communication; collecting communication traffic; generating an initial message sequence set; performing fuzzing on the protocol under test; collecting code coverage information and status feedback information generated during the runtime of the protocol entity under test, and determining whether the currently tested message sequence is an interesting message sequence; and then performing the next round of fuzzing. This invention is applicable to all network protocol fuzzing tools based on AFLNET improvements and has advantages such as simple implementation principle, strong code coverage and vulnerability discovery capabilities.
