Detailed Description
The embodiment of the application provides a method for isolating a power amplifier PA fault, a terminal device and a storage medium, which are used for improving the reliability of the terminal device and improving the probability of ensuring that a user is disconnected under the condition that the power amplifier has a fault.
For a person skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. The embodiments in the present application shall fall within the protection scope of the present application.
The following is a brief description of the terms referred to in this application, as follows:
a Customer Premise Equipment (CPE) is actually a mobile signal access device that receives mobile signals and forwards them out as Wireless Fidelity (WiFi) signals. The CPE can convert high-speed 4G/5G signals into WiFi signals, and the number of mobile terminals which can access the Internet simultaneously is large. The CPE can be widely applied to rural areas, towns, hospitals, units, factories, cells and the like, can be accessed by a wireless network, can save broadband cost and avoid wiring links.
The following is a description of the classification of CPE:
(1)4G CPE: as the name implies, the 4G CPE can convert a 4G Long Term Evolution (LTE) mobile network into broadband and WiFi. In addition, the 4G CPE also acts as a fully functional wireless router and can provide broadband connectivity and wireless networking for the end devices.
(2)5G CPE: if the 5G CPE is said to simply strengthen the WiFi signal, it does nothing, and after all, the WiFi router can also do it. It is really a harsh place to relay the handset signal (e.g., 5G/4G signal) twice. The received 5G/4G signal is changed into a WiFi signal, and the WiFi signal is provided for the equipment at the side. And carrying out secondary relay on the network signals of the operator by using the CPE.
Although operators have widely performed the 5G base station arrangement work so far and achieved considerable effects, the industrial data acquisition places are often in remote mountainous areas and reservoirs, which makes the 5G signal coverage relatively weak and the signals unstable. The signals are subjected to secondary relay through the 5G CPE TG463 industrial gateway, the coverage range of the 5G network is enlarged, the monitoring area is covered with the 5G network, and data are conveniently acquired and transmitted.
(3) Consumption CPE (Mobile phone card)
Consumer grade CPEs typically use a cell phone traffic card to suffice. The consumer-grade CPE can support 4G/5G full-Network communication, can obtain 4G/5G broadband and WiFi by plugging a 4G/5G SIM card, is downward compatible, provides different Local Area Network (LAN) ports and can support terminal equipment to realize wired internet access.
The consumer-grade CPE can be generally used in home, business or office scenes, and provides a flexible and convenient internet access mode for scenes without broadband.
(4) Industrial CPE (Internet of things card)
The internet of things card is also called an internet of things card or a Subscriber Identity Module (SIM) card, is an 2/3/4G card provided by mobile, telecommunication and Unicom operators, has the same appearance as a common SIM card, adopts a special number segment, and meets the requirement of intelligent hardware and internet of things industries on equipment networking. The industrial grade card is divided into two forms of a common card and a patch card. The 5G industrial CPE can provide a high-order Wireless broadband service for industrial equipment and vehicles by converting 5G signals into Wireless Local Area Network (WLAN) signals and providing industrial Network performance and guarantee with higher bandwidth, higher speed, lower delay, higher protection, and higher reliability for industrial customers, as well as providing Wireless broadband access service for industrial users.
Dual Connectivity (DC) is between LTE and other third Generation Partnership Project (3 GPP) radio Access technologies, and is currently most famous as EN-DC (EUTRAN NR-Dual Connectivity), and actually refers to a networking mode in which LTE is referred to as a "Master base station" (Master eNodeB), may also be referred to as a Master Cell Group (MCG), 5G is referred to as a "Secondary base station" (Secondary eNodeB), may also be referred to as a Secondary Cell Group (SCG), so as to provide a networking mode in which 4G &5G is smoothly compatible and continuously covered for users, and is also referred to as a current main mode of 5G evolution — Non-independent networking (Non Access Stratum, NSA).
A radio frequency front end refers to the portion of a communication system between an antenna and intermediate frequency (or baseband) circuitry. In this section the signal is transmitted in radio frequency form. For wireless receivers, the rf front-end typically includes: amplifiers, filters, frequency converters, and some rf connections and matching circuits.
The radio frequency front end includes a transmit path and a receive path. Few components of the transmission path, power amplification, filtering and the like. The devices of the receiving path are many, including Low Noise Amplifier (LNA), filter and other devices, including indexes such as gain, sensitivity, radio frequency receiving bandwidth, etc., and are designed according to the characteristics of the product, so as to ensure that useful radio frequency signals can be completely picked up from the space without distortion and transmitted to the subsequent circuits such as frequency conversion, intermediate frequency amplification, etc.
The radio frequency front end modules include Power Amplifiers (PAs), filters, duplexers, radio frequency switches, low noise amplifiers, receivers/transmitters, and the like. The power amplifier is responsible for amplifying the radio frequency signal of the transmitting channel; the filter is responsible for filtering the transmitting and receiving signals; the duplexer is responsible for the duplex switching of a Frequency Division Duplex (FDD) system and the radio Frequency signal filtering of a receiving/transmitting channel; the radio frequency switch is responsible for switching between receiving and transmitting channels; the low noise amplifier is mainly used for amplifying small signals in a receiving channel; the receiver/transmitter is used for frequency conversion and channel selection of radio frequency signals.
In the 5G era, performance degradation or functional failure of a Power Amplifier (PA) occurs, and it is common practice for a Customer Premise Equipment (CPE) to continue to use the PA to further deteriorate performance, which affects user experience. Once a functional failure occurs, the function is lost, and the terminal equipment is not available.
From the processing of the current communication device: when the function of a PA device of the terminal equipment is reduced, the fault processing of the terminal equipment can hardly be carried out, so that the user experience is poorer and poorer until the terminal equipment is damaged; when the PA device of the terminal equipment is functionally damaged, the communication of the network terminal of the client is unavailable, which seriously affects the use of the user.
Fig. 1 is a schematic diagram of a communication architecture of an existing NSA and SA. In order to meet the requirement of rapidly deploying 5G by some operators, a new networking architecture, namely Non-independent Networking (NSA), is newly introduced into the standard; the conventional 2/3/4G network adopts an architecture of independent networking (SA).
Currently, the global 5G network NSA deployment is still mainstream, mainly due to the following reasons:
based on the target of continuous coverage of the urban area of the initial 5G network, firstly, two decisive premises are considered; when the two premises are met simultaneously, the comparative factors such as the networking scheme, the performance, the cost, the terminal condition and the like are comprehensively analyzed.
The first precondition is that: whether the 5G frequency has the capability of supporting the construction continuous coverage
The 5G frequency band has a large influence on service perception, SA may be selected if the continuous coverage capability is provided, and NSA is preferred if the interoperation is too much due to failure to achieve continuous coverage.
The second precondition is that: whether a new 5G core network (5GC) needs to be introduced or not
The capabilities of the new core network may fully enable 5G functionality, necessitating the selection of NSAs without the introduction of 5 GCs.
From the evolution of current communication development, a networking mode of NSA is introduced, and since it can be connected with LTE and New Radio (NR) networking in a dual mode, two PAs are required during its operation.
Fig. 2 is a diagram illustrating an example system architecture of a terminal device in the embodiment of the present application. In fig. 2, the number of PAs in the NSA network is more than that in the normal design, especially for some combinations, such as low frequency power amplifier + low frequency power amplifier, intermediate frequency power amplifier + intermediate frequency power amplifier, high frequency power amplifier + high frequency power amplifier, the number of PAs should be theoretically twice that in the SA network if the design requirements can be arbitrarily combined randomly, in view of the completeness of the combination. In fig. 2, PA For NSA (PA For NSA) is a new PA type.
Fig. 3 is a schematic diagram illustrating an embodiment of a method for fault isolation of a power amplifier PA in an embodiment of the present application, where the method is applied to a terminal device, and the terminal device includes a first power amplifier and a second power amplifier. The embodiment of the method comprises the following steps:
