Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

First, the related technical content of the embodiment of the invention is introduced:

at present, a mobile phone is mainly a Dual SIM Dual Standby (DSDS) type, and since two SIM Identity modules share a set of Radio Frequency (RF) modules, in a scenario where there is a high requirement for low latency, the RF Module switches back and forth between a main card and an auxiliary card, which may cause the blocking of a main card data service and affect user experience. It is confirmed from market feedback that the stuck phenomenon in the dual-card dual-standby scenario is serious, mainly due to the fact that the secondary card establishes Radio Resource Control (RRC) after receiving the spam Paging message (Paging).

The spam Paging may refer to Paging other than telephone calls and short messages.

The sharing of a group of RF modules may be understood as sharing a group of RF resources, wherein sharing a group of RF resources specifically shares a set of RF hardware circuit and antenna.

In the related art, the above problem is mainly solved by using two ways of Dual SIM Dual Active (DSDA) and disabling the secondary card.

(1) DSDA adds a set of RF modules to solve this problem.

In a hardware setting, the DSDA adds a device to the RF module, which results in a great increase in cost.

In terms of software, the DSDA needs to handle scenes such as interference between different RF modules and switching, and the software complexity increases.

(2) Disabling the secondary card addresses this issue at the expense of the secondary card experience.

The adoption of the scheme of forbidding the auxiliary card can cause that the auxiliary card can not carry out data service, and carry out voice communication service without receiving telephone wirelessly, thus having poor user experience on the auxiliary card.

In order to solve the above problem, an embodiment of the present invention provides a method for responding to a paging message, which may be applied to a terminal device that includes at least two SIM cards that share a set of RF modules.

As shown in fig. 2A, a method for responding to a paging message according to an embodiment of the present invention may include:

201. the network device sends a paging message to the terminal device.

When the network device needs to establish connection with the terminal device, a paging flow is initiated, and the network device sends a paging message to the terminal device.

Paging is divided into Core Network (CN) initiated paging and Evolved Universal Terrestrial Radio Access Network (UTRAN) initiated paging.

(1) The paging initiated by the CN is used for establishing a signaling connection, and the paging initiated by the CN is divided into cooperative paging and non-cooperative paging.

The cooperative paging is to check, by a Radio Network Controller (RNC), whether the UE has signaling connection in other CN domains except for the paging domain, and if so, to issue a cooperative paging message through different channels.

The non-cooperative Paging means that the RNC directly issues a Paging message through a Paging Control Channel (PCCH) in a Paging area designated by the CN without checking whether the UE has signaling connection in other CN domains except the Paging domain.

(2) The paging initiated by the UTRAN may page the UE, which migrates the user from an idle state or an inactive state to a connected state by paging a corresponding initiated cell update procedure.

202. And the terminal equipment receives the paging message sent by the network equipment through the first SIM card.

The terminal equipment comprises at least two SIM cards, wherein the at least two SIM cards share one group of RF modules, and the first SIM card is one of the at least two SIM cards.

203. And the terminal equipment judges whether the second SIM card has data service.

The second SIM card is a SIM card different from the first SIM card in the at least two SIM cards, and the priority of the second SIM card is greater than that of the first SIM card.

Optionally, the terminal device includes two SIM cards, namely a first SIM card and a second SIM card, where the first SIM card is an auxiliary card and the second SIM card is a main card.

If the first SIM card has data service, executing the following steps 204 to 207; if the first SIM card does not have the data service, the above 101 may be executed in return.

Optionally, if the second SIM card currently has a data service and the priority of the data service is greater than or equal to the preset priority, the LTE high-definition call function of the first SIM card is turned off to support the first SIM card circuit domain falling back to 2G or 3G.

In the embodiment of the invention, different priorities can be set for different SIM cards existing in the terminal equipment, so that the data service of the SIM card with high priority can be preferentially ensured according to the priority of the SIM card.

Further, after the terminal device closes the LTE high-definition call function of the first SIM card, if the data service of the second SIM card is completed, the LTE high-definition call function of the first SIM card is opened to support the first SIM card to perform the voice call service in the PS domain.

Further, after the terminal device closes the LTE high-definition call function of the first SIM card, if the priority of the data service currently existing in the second SIM card is less than or equal to the preset priority, the LTE high-definition call function of the first SIM card is opened to support the first SIM card to perform the voice call service in the PS domain.

In the embodiment of the invention, different services also have different priorities, wherein the priority of the data service is greater than that of the voice call service.

In the embodiment of the invention, the service with high priority can be preferentially ensured according to different services with different priorities of the terminal equipment.

In CN, the nature of transmission is only two forms in nature: CS and PS.

A circuit switched domain (CS domain) and a packet switched domain (PS domain). Cs (circuit switched domain) domain: all network element entities in the core network that provide circuit-switched type connections for user services, and all network element entities that support the associated signaling. Circuit-switched connections allocate dedicated network resources when a connection is established and release dedicated resources when a connection is released.

The CS domain is a circuit-bearing domain and can be used for voice services, and the PS domain is a data-bearing domain and can be used for data services, for example, for mobile phone internet access.

In a 3G communication system, the access network may connect CS and PS simultaneously, i.e. the core network is split into CS and PS. Wherein the signals for making a call are transmitted through the CS domain and the signals for data services are transmitted through the PS domain.

In LTE, CS domain services can be implemented in PS domain. For example, LTE high definition telephony function (VoLTE) may be implemented in the PS domain.

204. And the terminal equipment closes the LTE high-definition call function of the first SIM card.

Since the CS domain service can be implemented in the PS domain in LTE, it cannot be determined whether the core network domain of the paging message is the PS domain or the CS domain when the LTE high-definition call function of the first SIM card is activated. At this time, the LTE high-definition call function of the first SIM card may be turned off to support the first SIM card circuit domain falling back to 2G or 3G, and after the first SIM card circuit domain falling back to 2G or 3G, it may be determined whether the core network domain is a PS domain or a CS domain.

It should be noted that the embodiment of the present invention does not limit the above 201 to 203, and the sequence of 204 may be executed first 204 and then 201 to 203, or 201 to 203 and then 204, or 201 to 203 and 204 may be executed simultaneously.

Optionally, a setting interface of the LTE high-definition call function, which facilitates a user to set the LTE high-definition call function (VoLTE call function), may be provided in the terminal device. As shown in fig. 2B, is an interface of the terminal device related to the set VoLTE call function, wherein the "phone" option is set as indicated by the arrow in fig. 2B. After the user clicks the "phone" option, an interface of the terminal device related to the set VoLTE call function as shown in fig. 2C may be further displayed, and a control for turning on or off the VoLTE call function as indicated by an arrow in fig. 2C is displayed in the interface. The user can trigger the terminal device to open or close the VoLTE call function through touch input aiming at the control.

In the embodiment of the invention, the user operation interface is set, so that the user can conveniently trigger the terminal equipment to start or close the VoLTE call function, and the man-machine interaction performance of the terminal equipment is improved.

205. The terminal equipment judges whether the core network domain of the paging message is a PS domain or a CS domain.

If the core network domain of the paging message is the PS domain, execute 206; if the core network domain of the paging message is the CS domain, the following 207 is performed.

206. The terminal device ignores the paging message.

The terminal equipment ignores the paging message, and can ensure the data service of the second SIM card.

207. And the first SIM card circuit domain of the terminal equipment falls back to the 2G or the 3G to carry out voice communication service.

Further, after the terminal device receives the paging message through the first SIM, if the core network domain of the paging message is the CS domain, the first SIM circuit domain of the terminal device falls back to 2G or 3G to perform the voice call service, so that the voice call service of the first SIM card can be ensured.

As shown in fig. 3, an embodiment of the present invention provides a terminal device, where the terminal device includes at least two SIM cards for user identification, and the at least two SIM cards share a set of RF modules, including:

a receiving module 301, configured to receive, through a first SIM card, a paging message sent by a network device, where the first SIM card is one of at least two SIM cards;

a processing module 302, configured to ignore the paging message if a core network domain of the paging message is PS, so as to ensure a data service of the second SIM card;

Optionally, the processing module 302 is further configured to, after the receiving module 301 receives the paging message sent by the network device through the first SIM card, if a core network domain of the paging message is a circuit switched CS domain, drop the first SIM card circuit domain back to 2G or 3G, and perform a voice call service.

Optionally, the processing module 302 is further configured to, after the receiving module 301 receives the paging message sent by the network device through the first SIM card, if a core network domain of the paging message is a CS domain, drop the circuit domain back to 2G or 3G, and close a long term evolution LTE high-definition call function of the first SIM card before responding to the paging message, so as to support the first SIM card circuit domain to drop back to 2G or 3G.

Optionally, the processing module 302 is specifically configured to close the LTE high-definition call function of the first SIM card if the second SIM card has a data service, so as to support the first SIM card circuit domain falling back to 2G or 3G.

Optionally, the processing module 302 is specifically configured to, if the second SIM card currently has a data service and the priority of the data service is greater than or equal to a preset priority, close the LTE high-definition call function of the first SIM card to support the first SIM card circuit domain falling back to 2G or 3G.

Optionally, the processing module 302 is specifically configured to, after the LTE high-definition call function of the first SIM card is closed, if the data service of the second SIM card is completed, or the priority of the data service currently existing in the second SIM card is less than or equal to the preset priority, open the LTE high-definition call function of the first SIM card to support the first SIM card to perform a voice call service in the PS domain.

As shown in fig. 4, an embodiment of the present invention further provides a terminal device, where the terminal device may include a processor 401, a memory 402, and a computer program stored in the memory 402 and capable of running on the processor 401, and when the computer program is executed by the processor, each process executed by the terminal device in the foregoing method embodiments may be implemented, and the same technical effect may be achieved, and details are not repeated here to avoid repetition.

Therein, the radio frequency circuit 510 includes a receiver 511 and a transmitter 512. Those skilled in the art will appreciate that the terminal device configuration shown in fig. 5 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

RF circuit 510 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, for processing downlink information of a base station after receiving the downlink information to processor 580; in addition, the data for designing uplink is transmitted to the base station. In general, RF circuit 510 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, RF circuit 510 may also communicate with networks and other devices via wireless communication. The wireless communication may use any communication standard or protocol, including but not limited to global system for mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Message Service (SMS), etc.

The memory 520 may be used to store software programs and modules, and the processor 580 executes various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 520.

Further, the memory 520 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 530 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 530 may include a touch panel 531 and other input devices 532. The touch panel 531, also called a touch screen, can collect touch operations of a user on or near the touch panel 531 (for example, operations of the user on or near the touch panel 531 by using any suitable object or accessory such as a finger or a stylus pen), and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 531 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, and sends the touch point coordinates to the processor 580, and can receive and execute commands sent by the processor 580. In addition, the touch panel 531 may be implemented by various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 530 may include other input devices 532 in addition to the touch panel 531. In particular, other input devices 532 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

The display unit 540 may include a display panel 541, and optionally, the display panel 541 may be configured in the form of a Liquid Crystal Display (LCD), an organic light-Emitting diode (OLED), or the like. Further, the touch panel 531 may cover the display panel 541, and when the touch panel 531 detects a touch operation on or near the touch panel 531, the touch panel is transmitted to the processor 580 to determine the type of the touch event, and then the processor 580 provides a corresponding visual output on the display panel 541 according to the type of the touch event. Although the touch panel 531 and the display panel 541 are shown as two separate components in fig. 5 to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 531 and the display panel 541 may be integrated to implement the input and output functions of the mobile phone.

The terminal device may also include at least one sensor 550, such as a light sensor, motion sensor, and other sensors.

As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.

Audio circuitry 560, speaker 561, and microphone 562 may provide an audio interface between a user and a cell phone. The audio circuit 560 may transmit the electrical signal converted from the received audio data to the speaker 561, and convert the electrical signal into a sound signal by the speaker 561 for output; on the other hand, the microphone 562 converts the collected sound signals into electrical signals, which are received by the audio circuit 560 and converted into audio data, which are then processed by the audio data output processor 580, and then passed through the RF circuit 510 to be sent to, for example, another cellular phone, or output to the memory 520 for further processing.

WiFi belongs to short distance wireless transmission technology, and the mobile phone can help the user to send and receive e-mail, browse web pages, access streaming media, etc. through the WiFi module 570, which provides wireless broadband internet access for the user. Although fig. 5 shows the WiFi module 570, it is understood that it does not belong to the essential constitution of the handset, and can be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 580 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 520 and calling data stored in the memory 520, thereby performing overall monitoring of the mobile phone. Alternatively, processor 580 may include one or more processing units; preferably, the processor 580 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into processor 580.
