Actually, I don't think this patent belongs to Huawei or Qualcomm.
Or to be precise, the flight mode function used in the era of smart phones is not directly related to the patents of Huawei or Qualcomm.
First of all, the name "flight mode" is not used in the patents of Huawei and Qualcomm. Qualcomm's patent is called "airplane and alarm clock mode" and Huawei's is called "state switching method of communication equipment". Therefore, the Chinese flight mode name is not occupied by any patent.
Huawei Qualcomm's invention patent is not the concept of "flight mode" itself, but the way to realize flight mode.
Then, two invention patents were born in the era of functional machines. At that time, many functions of the mobile phone depended on the existence of BP, and it could not even be turned on without inserting a card (because the baseband could not be initialized). Qualcomm Huawei's two invention patents focus on how to bypass the baseband control of mobile phones, so that mobile phones can work independently without the icon function of baseband chips.
There is no essential difference between the two patents. If we must compare, Huawei's patents are closer to reality. After all, Huawei's proposal is more feasible and clear.
Think Huawei's patent allows switching wifi, but Qualcomm doesn't? This should not be true. First of all, the full text of Huawei's Qualcomm patent does not involve wifi. Secondly, the function machine of 200 1 has no wifi function at all. The patents of Huawei Qualcomm are all applied for by 200 1, so it is impossible to relate to wifi-related functions.
In fact, this invention patent is only meaningful for feature phones. After all, they are studying how to make the mobile phone complete some functions when BP can't work normally.
The system in the era of smart phones is inherently independent of BP, and applications and mobile phone operating systems can be started independently, without any additional design, and smart phones without baseband and calling cards can work normally. Because the concept of flight mode is not a patent, and the method of realizing flight mode by smart phone is different from the patent of Qualcomm Huawei's function phone flight mode, flight mode can exist independently without any patent invention.
Huawei Qualcomm's patents on flight modes are all based on function machines, and only function machines need to invent specific methods to realize flight modes. Huawei's patents are indeed better described, but the flight mode in the era of smart phones does not need to rely on any patents. Therefore, this patent does not belong to Qualcomm or Huawei.
