Method for reducing SAR value of mobile terminal, storage medium and mobile terminal
The invention discloses a method for reducing an SAR value of a mobile terminal, a storage medium and a mobile terminal. The method comprises: detecting and comparing signal strengths of an upper antenna and a lower antenna of the mobile terminal in real time during a call; and when it is detected that the signal strength of the upper antenna of the mobile terminal is greater than that of the lower antenna, switching the communication work of the mobile terminal to the upper antenna, and reducing the radio frequency transmitting power of the upper antenna. By adoption of the scheme, the SAR value of the mobile terminal can be reduced.

Multi-tier quality of service wireless comfmunications networks
The present invention pertains to improved communication quality of service in communication networks. A customer may pay different fees for different tiers of service relating to voice quality and bandwidth access. Higher service tiers may guarantee that a specific vocoder or bit rate is used; or guarantee that communication is supported by parameters such as maximum allowed dropped calls rate, jitter and latency. Availability may be guaranteed per the contract between subscribers and service providers. Different tiers may be associated with customers' records for billing purposes. High end devices may be afforded higher voice quality by comparing a given device to a look up table indicating what service level is associated therewith. A calling device or a receiving device may ask the other device to change the vocoder or bit rate to ensure a higher quality call. The user may also change the quality level before or during a call.
