Description
The invention relates to the technical field of mobile phone communication, in particular to a method and a system for enhancing call experience.
In the communication process of the mobile phone, the communication states are mainly divided into the following types: 1. holding the head close to talk; 2. an earphone conversation; 3. and (4) carrying out hands-free conversation. In a call mode, the performance of the mode 1 is the worst and is the most complained by the user, because in the head-to-hand mode, the antenna has frequency offset and mismatch, which results in a great reduction of the antenna performance.
Today's mobile phones are required to support not only cellular frequencies, but also those non-cellular features used for mobile television, bluetooth, WLAN and location services. As the available space for the antenna is reduced each time a mobile phone is upgraded, the antenna is wrapped around the camera and keypad circuitry and the path is rearranged, resulting in reduced antenna efficiency. Some of the performance loss can be recovered by antenna tuning, i.e., using dynamic impedance tuning techniques to optimize the performance of the antenna based on operating frequency and environmental conditions. However, the challenge is that any successful antenna tuning scheme must meet the requirements of low loss, high linearity, ability to process very high strength RF signals, and low power consumption.
Antenna tuning architecture: when a passive antenna no longer meets performance requirements such as increased bandwidth requirements, more complex handset design, and smaller antenna available space, an open-loop antenna tuning system is typically used. In open-loop systems, the tunable element fine-tunes the performance of the antenna at a set frequency band and mode of operation based on static information (e.g., transmit/receive frequency, modulation scheme, or usage). However, since the open-loop system does not measure the operation condition of the antenna in real time, the environmental conditions cannot be considered specifically.
In mobile devices, environmental conditions are very important, and they change when a user walks, drives, or moves a finger. Antenna designers may use adaptive closed-loop antenna tuning techniques to cope with these condition changes. In a closed loop tuning scheme, a mismatch sensing element tracks the operating conditions of the antenna and provides a feedback signal reflecting the actual conditions.
The mismatch sensing unit compares the VSWR (amplitude of the power reflected back to the antenna) to the transmitted power and adjusts the impedance tuning circuit. The tuning algorithm allows the tunable element to continuously track the environmental conditions under various use conditions and to tune the impedance to an optimal value.
The theory is useful, but the biggest hurdle to achieving adaptive antenna tuning in cellular phones is the lack of high performance reactive elements with tunable electrical parameters, low loss, and sufficiently wide tuning ratios. In terms of "high performance", the most challenging component requirements are power handling capability and linearity. For example, a GSM antenna must typically be able to handle transmit powers up to +33dBm, but under mismatch conditions the tuning elements actually need to handle RF signals up to 30Vpk in voltage or up to +40dBm in power.
A great deal of research has been conducted over the last few years in search of better tuning materials. For example, to implement tunable antennas and filters, some researchers have used microelectromechanical systems (MEMS) and ferroelectric material technologies (e.g., barium strontium titanate, BST). Despite the promise of these technologies, significant technological and manufacturing obstacles are currently encountered. To adequately meet antenna tuning requirements, designers need techniques, preferably mature techniques, that support mass production.
The antenna is a complex device, and the antenna embedded in the mobile phone is no exception. Since the RF transceiver of the handset is designed for 50 Ω impedance, the antenna is preferably also 50 Ω impedance over the entire frequency band. In fact, however, this is rarely done because, according to the law of electromagnetism, a mobile phone inherently has the characteristics of narrow antenna bandwidth, poor matching, low radiation efficiency, and the like. Thus, antennas are typically designed with a non-50 Ω impedance throughout the band, with typical values of VSWR of 2:1 or 3:1 for multi-band antennas. The antenna impedance is also affected by other factors, such as the handset grip (i.e., "head-to-hand"). The user's body also absorbs power, further limiting the radiation efficiency of the antenna. The handset antenna typically operates at a VSWR of better than 3:1, but if the user places a finger on the antenna transmitter, the VSWR may increase to 9: 1. A problem may arise if all devices in the signal chain are designed at a VSWR of 1: 1. Fig. 1 shows the effect of the "head-hand effect", i.e. the shift (tuning) of the resonance point of the antenna when the hand is placed near the antenna radiator. This effect changes the resonant frequency of the antenna, resulting in a severe mismatch of the antenna at the intended operating frequency. When a user places his or her hand in the vicinity of the antenna radiator, the resonant frequency of the antenna changes, resulting in a mismatch at the predetermined operating frequency.
When the antenna ports are in a mismatched state, the RF performance degrades rapidly. It is particularly noted that if the antenna is in a state where VSWR is 3:1 (a common design criterion for multiband antennas), about 1.25dB of power is immediately lost due to reflection; if the VSWR reaches 5:1, the mismatch loss will increase to 2.55 dB. Such mismatch will also cause the Power Amplifier (PA) output power to drop, further reducing the radiated power. If the handset's narrowband duplex or receive filter is not terminated to its characteristic impedance, ripple will also appear in its passband, with an additional up to 2dB loss.
Head and hand effects, mismatch losses in the antenna, ripple in the RF filter passband, and PA output power droop together have a severe impact on the amount of power transmitted out of the handset antenna. The consequence of the shift in the resonance point is a reduced battery life, a reduced link range and a reduced call quality, and an increased number of drops. To address this problem, TRP (total radiated power) and TIS (isotropic sensitivity) specifications have been established by many service providers. To meet these specifications, the actual use case (for head and hand) must be simulated when testing the handset, rather than simply doing conductivity measurements in a 50 Ω environment or testing the phone in free space.
Adaptive antenna tuning is expected to be a good way to meet these new TRP and TIS specifications, and antenna tuners can give the antenna a 50 Ω characteristic independent of the environment and allow other parts of the system to operate under optimal conditions. Although the antenna tuner incurs some additional insertion loss, adaptive antenna tuning will greatly reduce the overall insertion loss from the tuner input to the antenna input, thereby improving performance, as compared to the case where no antenna tuner is added.
The antenna of a multi-band transceiving system requires an adaptive antenna tuning circuit capable of ensuring performance in the entire band up to the band edge, actively tracking the resonance point shift and quickly tuning back the resonance point of the antenna. The tuning circuit must have a very high linearity to avoid generation of harmonics or intermodulation distortion, and at the same time, should be small and robust, have a tuning ratio of at least 3:1, and have a power consumption of less than 1mA for the entire circuit. To effectively improve performance, the insertion loss of the circuit must be small, and therefore the quality factor (Q) should be at least 50.
The DuNE technology has been developed and patented by designers of Peregrine semiconductors based on the company's UltraCMOS process and the HaRP innovation design, DuNE Digital Tunable Capacitor (DTC) chips are designed to meet antenna tuning requirements, include high Q capacitors and a serial interface, and have the advantages of low bias voltage and high linearity, the device is packaged in a flip chip, and the size of the DuNE DTC facing a GSM/WCDMA handset is 1.36 × 0.81.81 mm.
In summary, the following technical solutions are still adopted to solve the problem of the talk in the handset mode at present: 1. the antenna resonance is adjusted to be compatible with two modes between a head-hand mode and a free space; 2. the mode at hand is taken as the main mode, and the free space performance is sacrificed; 3. the free space is taken as the main part, and the head and hand modes are considered. In addition, because the existing mobile phone is basically metalized and miniaturized, the antenna space is very small, and the performance of the mobile phone is not particularly good, so that the mobile phone is difficult to simultaneously consider the performances of various modes, and the problem of conversation experience still exists.

If the real-time position information received by one of the two mobile phones is sent by the mobile phone at the calling end in the process of calling, the calling can be selected to continue, and if the real-time position information is not sent by the mobile phone at the calling end, the calling can be selected to be interrupted.
It should be noted that the mobile phone and the opposite mobile phone that are in communication should both have the functions of acquiring the real-time location information, sending and receiving the real-time location information of the opposite mobile phone, mutually verifying the real-time location information of the opposite mobile phone, verifying whether the real-time location information is sent by the opposite mobile phone, and making a communication according to the verification result.
