This invention discloses an AI inference resource decoupling scheduling method and system based on a two-dimensional orthogonal state space. User AI service rights are decomposed into storage rights dimension σ and computing power rights dimension φ, constructing an orthogonal state space S=(σ,φ), where σ and φ change independently and have no causal dependency. Four service modes are derived from the state space: full service, read-only memory, temporary session, and guided recovery. State transitions in the computing power rights dimension are triggered by critical conditions of discrete quota counting: the cost r for a single token generation is defined as the lower limit of physical resources required for a single forward propagation of the model decoder. When the remaining quota Q(t) is less than r, the physical system cannot complete the next calculation, and the state will inevitably transition and terminate the computation flow. State switching is achieved through metadata-level atomic operations, and the execution time is independent of the user data scale. This invention clarifies the inevitability of the technical effect through logical deduction, is applicable to software or hardware-software co-implementation, and solves the problems of resource deadlock, switching latency, and service interruption under subscription systems.

This application discloses a communication handover method, a gateway device, a terminal device, and a readable storage medium. In this method, a first tunnel and a second tunnel sharing the same IP address are established with the first SIM card and the second SIM card of the terminal device, respectively. A primary tunnel and a backup tunnel are determined from the first and second tunnels. The forwarding direction of the active data stream is determined to be the primary tunnel, and the active data stream is transmitted using the primary tunnel in conjunction with IP. A tunnel handover request sent by the terminal device is received, and the forwarding direction of the active data stream is switched to the backup tunnel. The active data stream is transmitted using the backup tunnel in conjunction with IP. This application achieves network handover simply by changing the forwarding direction of the active data stream, without requiring IP address changes or session reconstruction, effectively shortening network handover latency.

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may operate according to active bandwidth parts (BWPs) for multiple component carriers (CCs). A network entity may transmit a non-scheduling downlink control information (DCI) message that indicates, to the UE, BWP switches for multiple CCs. The non-scheduling DCI message may repurpose bits from downlink data scheduling fields to indicate the BWP switches. The UE may receive the non-scheduling DCI message and perform the BWP switches for the multiple CCs. If the UE receives multiple DCI messages indicating BWP switches, the UE may perform the BWP switches in accordance with a quantity of CCs for BWP switching and a reference time. The UE may start a BWP switching delay at the reference time, where the reference time is associated with a resource allocated for feedback by at least one of the multiple DCI messages.

A method and system for determining a switching delay for a user equipment (UE) in a wireless communication network are disclosed. The network device determines a search space set group switching capability of the UE based on UE-reported information such as UE category or physical downlink shared channel (PDSCH) processing capability and transmits a target switching delay to the UE according to a minimum switching delay corresponding to the UE's switching capability. The switching capability may include different levels (e.g., first, second, or third switching capabilities), and the target switching delay is adjusted accordingly, with delays scaled based on UE category (e.g., first-category or second-category UE). The method may also account for sub-carrier spacing associated with the UE's bandwidth. Communication between the network and the UE includes radio resource control (RRC) signaling and downlink control signaling to coordinate switching between search space set groups.

This invention provides a collaborative method for handover decision-making and power allocation in mobile phone direct connection to low-Earth orbit satellite networks, belonging to the field of mobile phone direct connection to low-Earth orbit satellite communication. This invention decouples the original handover problem into two sub-problems: the handover decision of the source satellite and the downlink power allocation of the target satellite. Specifically, the source satellite uses a genetic algorithm to make decisions on user handover timing and target, thereby improving overall handover performance; after the user connects to the target satellite, the latter uses a continuous convex approximation algorithm to jointly optimize the downlink power of both new and existing users, thereby maximizing the system's downlink throughput. This method can effectively improve the handover success rate, reduce handover latency, achieve system load balancing, and significantly improve the downlink throughput of the target satellite after user handover, realizing overall optimization of the handover process in mobile phone direct connection to low-Earth orbit satellite networks.

This invention relates to the field of communication bus technology, and more particularly to a multi-master IIC bus control system and its dynamic arbitration method, including a parameter configuration unit, a dynamic arbitration unit, a dynamic role switching unit, and a slave data synchronization unit. Dynamic arbitration is achieved through a wired-AND mechanism and a readback detection mechanism: the master node determines the arbitration status by comparing its output level with the bus readback level, and switches to slave upon failure; the slave node switches to master upon detecting a bus idle timeout. The slave data synchronization unit captures bus timing data in real time to ensure zero-delay takeover during master-slave switching. During the power-on initialization phase, master and slave roles are allocated through contention timing. This invention solves the problems of bus conflict, switching delay, and data loss in multi-master scenarios, significantly improving system reliability and real-time performance, and is suitable for redundant control and high-reliability equipment.
