Abstract: A wireless communication method and device are provided. The wireless communication method includes the steps of receiving a Traffic Flow Template (TFT) which is assigned by a network; determining whether a first evaluation precedence index (EPI) corresponding to a new packet filter of the TFT is the same as a second EPI corresponding to an old packet filter which belongs to an evolved packet system (EPS) bearer or a packet data protocol (PDP) context; determining whether the new packet filter belongs to the EPS bearer or the PDP context when the first EPI is the same as the second EPI; and replacing the old packet filter with the new packet filter without deleting the EPS bearer or the PDP context when the new packet filter belongs to the EPS bearer or the PDP context.

Abstract: A memory management system includes a memory, a processor, a memory access monitoring module and a memory management module. The processor is used to access the memory. The memory access monitoring module includes a first terminal coupled to the processor, and a second terminal coupled to the memory. The memory access monitoring module is used to monitor whether the processor has accessed the memory so as to generate monitor data. The memory management module is used to receive the monitor data and predict when the memory is to be accessed according to at least the monitor data.

Abstract: A system includes a memory and multiple processors. The memory further includes a shared section and a non-shared section. The processors further include at least a first processor and a second processor, both of which read-only access to the shared section of the memory. The first processor and the second processor are operable to execute shared code stored in the shared section of the memory, and execute non-shared code stored in a first sub-section and a second sub-section of the non-shared section, respectively. The first processor and the second processor execute the share code according to a first scheduler and a second scheduler, respectively. The first scheduler operates independently of the second scheduler.

Abstract: A method for handling a PDN disconnection request performed by a communications apparatus communicating with a network device includes transmitting a PDN disconnect request message to the network device to request to disconnect a predetermined PDN connection; receiving a PDN disconnect reject message from the network device; obtaining a reject cause carried in the PDN disconnect reject message; and locally deactivating all other PDN connection(s) other than the predetermined PDN connection when the reject cause carried in the PDN disconnect reject message indicates that the last PDN disconnection is not allowed.
