The program or instructions, when executed by a processor, causes the processor to perform the steps of any one of the above information obtaining method, with the same technical effect achieved, which will not be repeated here to avoid repetition.
The processor is the processor in the network device or UE described in the above embodiment. The readable storage medium includes a computer readable storage media, such as computer read-only memory (ROM), random access memory (RAM), magnetic disk or optical disk, etc.
It should be further noted that the UEs described in this specification include but are not limited to smartphones, tablet computers, etc., and many functional components described here are referred as modules to more specifically emphasize independence of their implementation.
In embodiments of the present disclosure, modules may be implemented in software so as to be executed by various types of processors. For example, an identified module of executable code may include one or more physical or logical blocks of computer instructions, which may be structured, for example, as an object, procedure, or function. Nonetheless, the executable code of an identified module need not be physically located together, but may include different instructions stored on different locations; when these instructions are logically combined together, they form a module and achieve the specified purpose of the module.
In fact, an executable code module may be a single instruction or many instructions, and may even be distributed over multiple different code segments, distributed among different programs, and distributed across multiple memory devices. Similarly, operational data may be identified within modules and may be implemented in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations (including on different storage devices), and may exist, at least in part, solely as electronic signals on a system or network.
When the module can be implemented by software, taking into account the level of existing hardware technology, those skilled in the art can build corresponding hardware circuits to implement the corresponding functions without considering the cost. The hardware circuits include conventional very large scale integration (VLSI) circuits or gate arrays as well as existing semiconductors such as logic chips, transistors, or other discrete components. Modules may also be implemented by using programmable hardware devices, such as field programmable gate arrays, programmable array logic, programmable logic devices, etc.
