Description
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to a service processing method based on a dual card terminal and a dual card terminal.
Background
In a Long Term Evolution (LTE) system, the maximum bandwidth is 20 Mhz. For an enhanced long term evolution (LTE-Advanced, LTE-A for short) system, the peak rate of the LTE-A system is greatly improved compared with the LTE system, and the LTE-A system is required to reach 1Gbps downlink and 500Mbps uplink. Clearly, a bandwidth of 20Mhz has not been able to meet this requirement. In order to meet the requirements of the LTE-a system, the 3GPP (the 3rd Generation Partnership Project, third Generation Partnership Project) defines a Carrier Aggregation (CA) technology in release 10, i.e., a plurality of carriers in the same frequency band or different frequency bands are aggregated to form a larger bandwidth, and simultaneously serve a terminal when necessary, so as to provide a data rate required by the terminal. Through CA, the resource utilization rate can be maximized, and discrete spectrum resources can be effectively utilized.
Currently, a terminal supporting LTE carrier aggregation generally includes two transceivers, one of which is a primary transceiver and the other is a secondary transceiver. When the terminal works in a carrier aggregation mode, two transceivers in the terminal work simultaneously, namely, when the transceiver 1 in the terminal processes data service signals, the transceiver 2 can also process the data service signals simultaneously through a carrier aggregation technology; when the terminal does not work in the carrier aggregation mode, only one transceiver is working, and the other transceiver is idle, for example, while the transceiver 1 of the terminal processes the LTE signal, the terminal receives a 2G or 3G voice signal. At present, in a non-carrier aggregation mode, a transceiver 1 and a transceiver 2 cannot simultaneously transmit and receive, so that when the transceiver 2 processes a voice service, a data service of the transceiver 1 is interrupted, and only one card can work, that is, so-called single pass, so that the service processing method of the existing dual-card terminal not only reduces the processing rate of LTE data of the transceiver 1, but also does not realize a dual-pass state of the terminal in a non-carrier aggregation state.

a first transceiver in the terminal receives a first downlink modulation signal and a second downlink modulation signal; the frequency band of the first downlink modulation signal is different from the frequency band of the second downlink modulation signal, the first downlink modulation signal is a signal corresponding to a data service, and the second downlink modulation signal is a signal corresponding to a voice service;
the first transceiver demodulates the first downlink modulation signal and sends the second downlink modulation signal to a second transceiver in the terminal;

Detailed Description
In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the embodiment of the present application, the terminal may be a wireless terminal or a wired terminal, and may be, for example, a mobile phone, a computer, a tablet computer, a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a wearable device, an electronic book reader (e-book reader), and the like.
The embodiment of the application is applicable to LTE and other networks capable of supporting Carrier aggregation technologies, such as supporting Dual Carrier technology (Dual Carrier) Universal Mobile telecommunications System Terrestrial Radio Access Network (UTRAN for short), supporting Downlink Dual Carrier technology (Downlink Dual Carrier) Enhanced Data Rate Global Mobile telecommunications System evolution technology Radio Access Network (GERAN for short), and the like.
The embodiment of the application can be used for various CA scenes and is not limited to intra-station CA, inter-station CA, heterogeneous network CA and the like.
In the context of the present application, the term "terminal" includes, but is not limited to, a mobile station, a fixed or mobile subscriber unit, a pager, a cellular telephone, a Personal Digital Assistant (PDA), a computer, or any other type of user equipment capable of operating in a wireless environment. The term "base station" includes, but is not limited to, a base station, a node, a station controller, an Access Point (AP), or any other type of interfacing device capable of operating in a wireless environment.
With reference to the above description, as shown in fig. 1, a schematic flow chart of a service processing method based on a dual-card terminal provided in an embodiment of the present application is shown, where the method includes:
step 101, a first transceiver in a terminal receives a first downlink modulation signal and a second downlink modulation signal; the frequency band of the first downlink modulation signal is different from the frequency band of the second downlink modulation signal, the first downlink modulation signal is a signal corresponding to a data service, and the second downlink modulation signal is a signal corresponding to a voice service.
And 102, the first transceiver demodulates the first downlink modulation signal and sends the second downlink modulation signal to a second transceiver in the terminal.
Step 103, the second transceiver demodulates the second downlink modulation signal.
In step 101, the terminal may further include a multiplexer, an antenna, a power amplifier, and other devices; the receiving end of the multiplexer is connected with the antenna, the output end of the multiplexer is connected with the first transceiver, wherein the multiplexer comprises a receiving end and four output ends if the multiplexer is a quadruplex multiplexer, wherein two output ends (a first downlink output end and a first uplink output end) of the four output ends are used for transmitting signals on the first transceiver, and the other two output ends (a second downlink output end and a second uplink output end) are used for transmitting signals on the second transceiver.
The terminal can receive the signal input by the antenna through the multiplexer, and then sends the first modulation signal and the second modulation signal to the first transceiver.
In the embodiment of the present application, the first modulation signal may be a signal corresponding to an LTE data service, and may also be a signal corresponding to a 5G data service; the second modulation signal is a signal corresponding to the 2G/3G voice service.
In the embodiment of the application, the terminal can be determined to work in the non-carrier aggregation mode through an operation service provider or through communication interaction with the base station. For example, currently, the carrier aggregation service is not provided by the indonesian communication service provider, so that when the operation service provider is the indonesian communication service provider, it can be determined that the terminal is in the non-carrier aggregation mode. Of course, the terminal may determine whether the terminal is in the carrier aggregation mode by looking up a table, querying the network, and determining the communication system, which is not described herein again.
In the embodiment of the present application, the frequency band in which the first modulation signal is located and the frequency band in which the second modulation signal is located may be signals in different frequency bands, and the frequency bands may include a B1 frequency band, a B2 frequency band, a B3 frequency band, a B5 frequency band, a B8 frequency band, and the like. For example, the frequency band of the first modulation signal is the B1 frequency band, and the frequency band of the second modulation signal is the B2 frequency band. The specific determination may be determined according to actual situations, and details are not described herein.
It should be noted that the frequency band of the first modulation signal is different from the frequency band of the second modulation signal, and the modulation modes are different, so that different transceivers can demodulate different signals through different demodulation modes, and the first power amplifier and the second power amplifier can simultaneously amplify the modulation signals of different frequency bands.
In the prior art, a terminal adopting a carrier aggregation architecture can only modulate and demodulate one signal at the same time, so that when the first transceiver modulates and demodulates a second signal, the first transceiver needs to interrupt the currently modulated and demodulated first signal and modulate and demodulate the second signal; or after the first transceiver sends the second signal to the second transceiver, when the second transceiver demodulates the second signal, the second transceiver cannot send out the modulated signal through the first transceiver, that is, in the prior art, the two transceivers cannot simultaneously receive and transmit, so that the processing efficiency of the first transceiver for processing the data service corresponding to the first modulated signal is reduced, and the dual-card terminal cannot realize dual-pass.
For example, as shown in fig. 2, a schematic diagram of an operation timing sequence of a terminal operating in a non-carrier aggregation mode in the prior art is shown. In fig. 2, the abscissa represents time; a 1 in the ordinate indicates that the transceiver is demodulating the signal and a 0 indicates that the transceiver is not demodulating the signal. As can be seen from fig. 2, when the terminal operates in the non-carrier aggregation mode, the first transceiver needs to periodically interrupt the first modulated signal being demodulated and demodulate the second modulated signal when demodulating the first modulated signal, so as to determine whether there is voice traffic sent to the terminal. And when the terminal determines that the voice service sent to the terminal exists according to the demodulated second modulation signal, the terminal preferentially demodulates the second modulation signal. While the second transceiver remains idle during operation of the first transceiver.
It should be noted that, when the terminal monitors whether there is a voice service sent to the terminal, it needs to demodulate and analyze the received signal, but the first transceiver cannot demodulate the first modulation signal and the second modulation signal at the same time, so the terminal must suspend demodulating the first modulation signal when there is a voice service sent to the terminal through the first transceiver.
In addition, as shown in fig. 3, which is another implementation method in the prior art, a working timing diagram of the terminal working in the non-carrier aggregation mode is shown. In fig. 3, the abscissa represents time; a 1 in the ordinate indicates that the transceiver is demodulating the signal and a 0 indicates that the transceiver is not demodulating the signal. As can be seen from fig. 3, when the terminal operates in the non-carrier aggregation mode, the first transceiver does not need to periodically interrupt the first modulated signal being demodulated when demodulating the first modulated signal, but sends the first modulated signal and the second modulated signal to the second transceiver through the carrier aggregation CA channel between the first transceiver and the second transceiver, and the second transceiver demodulates the second modulated signal, so as to determine whether there is voice traffic sent to the terminal. When it is determined that there is voice traffic being sent to the terminal, then the first transceiver may interrupt the first modulated signal being demodulated while receiving and demodulating the second modulated signal. Therefore, even if the first transceiver performs the task of periodically demodulating the second modulation signal through the second transceiver, the first transceiver does not need to periodically suspend demodulating the first modulation signal, but finally when the voice service on the secondary card is monitored, the data service still needs to be suspended when the first transceiver performs the demodulation of the voice service, so that the dual-card terminal in the technology still cannot perform the voice call on the secondary card, the data internet access service of the main card is not interrupted, and the dual-card terminal is still in the single-pass mode.
Based on the analysis of the prior art, the dual card terminal cannot simultaneously perform internet access and voice call because transceiving communication between the first transceiver and the second transceiver and the multiplexer cannot be performed simultaneously, so in the embodiment of the present application, by improving the circuit between the first transceiver and the second transceiver, two transceivers can simultaneously perform transmission and reception, as shown in fig. 4, in the figure, the solid line represents a downlink signal, and the dotted line represents an uplink signal, where the bold line between the first transceiver and the second transceiver represents the CA uplink path and the CA downlink path between the first transceiver and the second transceiver, respectively.
In fig. 4, the processing procedure of the downlink signal is as follows: the receiving end of the multiplexer receives LTE data service signals and 2G/3G voice service signals transmitted by the antenna, the multiplexer sends the LTE data service signals to the first transceiver by using the first downlink output end, the multiplexer sends the 2G/3G voice service signals to the first transceiver by using the second downlink output end while demodulating the LTE data service signals, the first transceiver sends the 2G/3G voice service signals to the second transceiver by using the CA downlink channel, and the second transceiver demodulates the 2G/3G voice service signals.
In fig. 4, the processing procedure of the uplink signal is as follows: the second transceiver sends the 2G/3G voice service signal to the first transceiver through a CA uplink channel, the first transceiver sends to the second power amplifier, then the second power amplifier outputs the amplified 2G/3G voice service signal to the antenna through the receiving end of the multiplexer, the signal is transmitted to a coverage area through the antenna, meanwhile, the first transceiver sends the LTE data service signal to the first power amplifier, then the first power amplifier outputs the amplified LTE data service signal to the antenna through the receiving end of the multiplexer, and the signal is transmitted to the coverage area through the antenna.
Further, as shown in fig. 5, a schematic diagram of an operation timing sequence of the terminal operating in the non-carrier aggregation mode in the embodiment of the present application is shown. In fig. 5, the abscissa represents time; a 1 in the ordinate indicates that the transceiver is demodulating the signal and a 0 indicates that the transceiver is not demodulating the signal. As can be seen from fig. 5, when the main card in the terminal accesses the internet, the sub-card periodically monitors whether there is a voice service sent to the sub-card of the terminal, where the monitoring means that the terminal demodulates the second modulation signal through the second transceiver, that is, demodulates a signal corresponding to the voice service, and then the terminal transmits data obtained after demodulating the second modulation signal to a Central Processing Unit (CPU), and the CPU analyzes data content according to a communication protocol, so as to determine whether there is a voice service sent to the sub-card of the terminal.
In the above process, the CPU may analyze data obtained by the demodulated second modulated signal according to the specification in the existing mobile communication protocol, so as to determine whether there is a voice service transmitted to the terminal. How to analyze specifically is not described herein.
Further, if the terminal determines, according to the demodulated second modulation signal, that the second modulation signal is a signal corresponding to the voice service sent to the terminal secondary card, the second modulation signal demodulated by the second transceiver may be performed while the first transceiver demodulates the first modulation signal.
Based on the same inventive concept, the embodiment of the present application further provides a terminal, and the terminal can execute the method.
