Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without any creative work, fall within the scope of protection of the present application.

[0058] It should be noted that the terms “include”, “contain” and “have” and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover the inclusion rather than the exclusion. For example, a process, method, terminal, product or device including a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to the process, method, product or device. In the claims, specification and drawings of the present application, the relationship terms such as “first” and “second” and the like are only used to distinguish one entity / operation / object from another entity / operation / object, and do not necessarily require or imply any actual relationship or sequence between the entities / operations / objects.

[0059] Reference herein to “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments.
