Description

Data transmission method, device, user equipment and modem chip

Technical Field

The present invention relates to data communication technologies, and in particular, to a data transmission method and apparatus, a user equipment, and a modem chip.

Background

With The development of communication technology, The emergence of The Fourth Generation mobile communication (4G) network has satisfied The demand of people for data services.

Data services of Long Term Evolution (LTE) and fifth-Generation mobile communication (5th-Generation,5G) have the characteristic of being always on. For example, when a UE attaches to LTE, it may request to establish a Packet Data Network (PDN) connection by default. The user equipment and the network side equipment keep long data bearing connection, so that data service of the User Equipment (UE) keeps an Internet Protocol (IP) online for a long time. That is, as long as the user equipment is not turned off, the IP data bearer established by the user equipment and the network-side device will maintain a connected state (Always on IP connectivity).

After the UE closes the mobile data switch, since the LTE or 5G mobile data service has a feature of being always on, there is still a data interaction situation between the UE and the network side device in the communication protocol layer. After receiving various data packets of the network side equipment, the UE still responds to the data packets, which causes power consumption of the UE.

The wireless communication may also include, but is 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), email, Short Messaging Service (SMS), and the like.

The memory 1120 may be used to store software programs and modules, and the processor 1180 may execute various functional applications of the user equipment and data processing by operating the software programs and modules stored in the memory 1120. The memory 1120 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the user equipment, and the like. Further, the memory 1120 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 1130 may be used to receive input gesture information, number or character information, and generate key signal inputs related to user settings and function control of the user equipment 100. Specifically, the input unit 1130 may include a touch screen 1131 and other input devices 1132. The touch screen 1131 may collect touch operations performed by a user on or near the touch screen 1131 (for example, operations performed by the user on or near the touch screen 1131 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. Specifically, the touch operation may include one or more of the following operation modes: such as a first pressure operation, a touch operation (e.g., a slide operation, a drag operation), a click operation, a multi-touch operation, a button input, a long press input, and the like. Optionally, the Touch screen 1131 may include a Touch Sensor (Touch Sensor) and/or a pressure Sensor (Force Sensor) for detecting a Touch signal and/or a pressure signal of a user, converting the Touch signal into Touch point coordinates and other Touch information, converting the pressure signal into a pressure value and other pressure information, and then transmitting the information to the processor 1180, and receiving and executing a command sent by the processor 1180. In addition, touch screen 1131 can be implemented using various types, such as resistive, capacitive, infrared, and surface acoustic wave. The input unit 1130 may include other input devices 1132 in addition to the touch screen 1131.

Although in FIG. 1, touch screen 1131 and display screen 1141 are shown as two separate components to implement the input and output functions of the user equipment, in some embodiments, touch screen 1131 and display screen 1141 may be integrated to implement the input and output functions of the user equipment.

The user equipment may also include at least one sensor 1150, such as pressure sensors, light sensors, motion sensors, and other sensors.

Audio circuitry 1160, speaker 1161, and microphone 1162 may provide an audio interface between a user and user equipment. The audio circuit 1160 may transmit the electrical signal converted from the received audio data to the speaker 1161, and convert the electrical signal into a sound signal for output by the speaker 1161; on the other hand, the microphone 1162 converts collected sound signals into electrical signals, which are received by the audio circuit 1160 and converted into audio data, which are then processed by the audio data output processor 1180, and then passed through the RF circuit 1110 for transmission to, for example, another piece of user equipment, or output to the memory 1120 for further processing.

WI-FI belongs to short-distance wireless transmission technology, and user equipment can help users to transmit and receive through a WI-FI module 1170Electronic mailBrowsing web pages, accessing streaming media, etc., which provide wireless broadband internet access to users. While FIG. 7 illustrates a WI-FI module 1170, it is to be understood that it does not pertain to a required component of user equipment and may well beAs necessary, they are omitted within a range not changing the essence of the invention.

The processor 1180 is a control center of the user equipment, connects various parts of the entire user equipment using various interfaces and lines, and performs various functions of the user equipment and processes data by operating or executing software programs and/or modules stored in the memory 1120 and calling up data stored in the memory 1120, thereby performing overall monitoring of the user equipment. Optionally, processor 1180 may include one or more processing units; preferably, the processor 1180 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications.

Fig. 2 is a schematic diagram of an LTE network architecture 100, and as shown in fig. 2, the LTE network architecture 100 may be referred to as an Evolved Packet System (EPS) 100. The EPS 100 may include one or more User Equipment (UE)102 and Network side devices including, but not limited to, Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) 104, Evolved Packet Core (EPC) 110, and operator Internet Protocol (IP) services 122. The EPS may interconnect with other access networks, but for simplicity those entities/interfaces are not shown. As shown, the EPS provides packet switched services, however, as those skilled in the art will readily appreciate, the various concepts presented throughout this disclosure may be extended to networks providing circuit switched services.

The E-UTRAN includes evolved Node B (eNB) 106, other enbs 108, and Multicast Coordination Entity (MCE) 128. The eNB 106 provides protocol terminations towards the user plane and the control plane of the UE 102. The eNB 106 may connect to other enbs 108 via a backhaul (e.g., an X2 interface). The eNB 106 may also be referred to as a base station, a node B, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a Basic Service Set (BSS), an Extended Service Set (ESS), or some other suitable terminology. eNB 106 provides an access point to EPC 102 for UE 110. Examples of UEs 102 include cellular phones, smart phones, Session Initiation Protocol (SIP) phones, laptops, Personal Digital Assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, or any other similar functioning devices. UE 102 may also be referred to by those skilled in the art as a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology.

eNB 106 is connected to EPC 110. EPC 110 may include Mobility Management Entity (MME)112, Home Subscriber Server (HSS)120, other MMEs 114, serving gateways 116, Multimedia Broadcast Multicast Service (MBMS) gateway 124, broadcast multicast service center (BM-SC)126, and Packet Data Network (PDN) gateway 118. MME 112 is a control node that handles signaling between UE 102 and EPC 110. Generally, the MME 112 provides bearer and connection management. All user IP packets are passed through the serving gateway 116, the serving gateway 116 itself being connected to the PDN gateway 118. The PDN gateway 118 provides IP address allocation as well as other functions for the UE. The PDN gateway 118 and BM-SC 126 are connected to the IP service 122. The IP services 122 may include the internet, intranets, IP Multimedia Subsystem (IMS), PS streaming services (PSs), and/or other IP services.

In an actual communication process, when acquiring an LTE service, a UE needs to attach to an Evolved Packet System (EPS) deployed by a certain operator. In the EPS attach process, a default EPS bearer, that is, a user bearer with default security performance, is established among the terminal, the access Network, the core Network, and an external Packet Data Network (PDN). Of course, other special bearers, that is, user bearers with special security and transmission capabilities, may also be established according to user service needs. And transmitting data packets of all data services of the LTE user in an uplink or downlink manner on the established EPS bearing channel.

Current UE devices that support cellular communication and User Interface (UI) are generally classified into a modem (modem) system and an Application Processor (AP) system. The modem system is a baseband subsystem responsible for implementing the protocol stack for cellular communications. The application processor system is an application processing subsystem responsible for running drivers, kernels, middleware, and applications. The networking application of the application processor system communicates with the network side device via the modem system. The modem system and the application processor system may each sleep independently.

And the user opens a mobile data switch of the UE on the user interface (the state of the mobile data switch of the UE is changed from off to on), and the UE and the network side equipment establish the EPS bearer. After the user closes the mobile data switch of the UE on the user interface (the state of the mobile data switch of the UE is changed from on to off), the UE does not tear down the existing EPS bearer. Only the AP system locally removes the IP connection, and the networking application in the AP system considers that the connection with the network side device is disconnected, so that the IP packet is not sent to the network side device any more. However, the modem system of the UE still maintains the EPS bearer, and the server of the network side device still considers the networking application of the UE to be online until the heartbeat thereof cannot be synchronized or the aging timer of the IP connection times out. If the network side device has a data packet to be transmitted to the UE, the data packet can still be transmitted on the EPS bearer.

Fig. 3 is a schematic view of a communication protocol flow for establishing Radio Resource Control (RRC) connection between the UE and the network side device. As shown in fig. 3, in the LTE communication protocol flow, the UE communicates with an evolved Node B (eNB) on the network side. After the UE establishes the EPS bearer with the network side equipment, the network side equipment issues an RRC paging message to the UE side. And after receiving the RRC Paging message, the UE responds to the RRC Paging message. The UE initiates an RRC Connection Request (RRC Connection Request) to the network side equipment, and the network side equipment establishes RRC Connection with the UE after receiving the RRC Connection Request sent by the UE. When the RRC Connection established between the UE and the network side equipment is not needed any more, the network side equipment sends an RRC Connection Release (RRC Connection Release) message to the UE, and the UE releases the RRC Connection with the network side equipment after receiving the RRC Connection Release message.

Since the modem system of the UE still maintains the EPS bearer, the network side device may still attempt to send a packet to the UE. For example, the UE receives an RRC paging (paging) message sent by the network side device, and if a value (value) of a core network domain (CN-domain) field of the message is ps, the UE establishes an RRC connection with the network side device. Typically, the RRC connection establishment lasts 10 seconds after success. Since the data switch of the UE is turned off, the IP packet received by the modem is not forwarded to the AP. The wake-up of the Modem to RRC establishment and the continuous power consumption are not necessary for the UE.

In order to solve the problem that after a mobile data switch of the UE is turned off, the UE can still receive a data packet issued by network side equipment, so that the power consumption of the UE is wasted, the embodiments of the present invention provide some solutions.

Fig. 4 is a flowchart of a method of data transmission according to an embodiment of the present invention. The execution subject of the method flow is the user equipment supporting LTE or 5G mobile data communication. Specifically, the main execution body of the method flow is a modem chip in the user equipment. The process flow of the method comprises the following method steps.

S101, the UE receives a paging message sent by the network side equipment.

Because the LTE data service has the characteristic of being always on, after the user equipment supporting LTE or 5G mobile data communication and the network side device successfully establish the EPS bearer, the network side device may issue a paging message to the UE through the EPS bearer.

S103, when the paging message is used for identifying the data service and the mobile data of the UE is closed, ignoring the paging message.

And after receiving the paging message sent by the network side equipment, the UE analyzes the paging message. When the paging message is used for identifying a data service, according to the existing LTE communication protocol, the UE initiates an RRC connection request to the network side device, requesting to establish an RRC connection with the network side device, so that the UE performs a subsequent data service, such as an application messaging service.

Fig. 5 is a flowchart of another data transmission method according to an embodiment of the present invention. The execution subject of the method flow is the user equipment supporting LTE or 5G mobile data communication. Specifically, the main execution body of the method flow is a modem chip in the user equipment. When the mobile data of the user equipment is closed, the terminal does not respond to the paging message when receiving the paging message issued by the network side equipment. In the following, taking the user equipment as a mobile phone as an example, a specific implementation process of the scheme is described, as shown in fig. 5.

S201, the mobile phone and the network side equipment successfully establish the EPS bearer.

The handsets shown in fig. 6 a-6 c are LTE enabled terminals. As shown in fig. 6a, the user clicks the mobile data switch on the switch setting interface of the mobile phone 100, the mobile data switch changes from the non-highlighted state to the highlighted state, and the mobile data switch of the mobile phone 100 is turned on. After the mobile data switch of the mobile phone is turned on, the application processor in the mobile phone records the state information of the current mobile data switch as on. The mobile phone establishes communication connection with the network side equipment through LTE service, and the UE establishes EPS bearing with the network side equipment when attached to the LTE network.

S203, the mobile data of the mobile phone is closed.

As shown in fig. 6b, the user clicks the mobile data switch on the switch setting interface of the mobile phone 100 again, the mobile data switch is changed from the highlighted state to the non-highlighted state, and the mobile data switch of the mobile phone is turned off. After the mobile data switch of the mobile phone is closed, the application processor in the mobile phone records the state information of the current mobile data switch as closed again. And the application processor of the mobile phone locally removes the IP connection and does not instruct the modem to send the IP message to the network side equipment any more.

Alternatively, the mobile data switch of the mobile phone is turned off, which may be performed by the user or automatically by the mobile phone. For example, according to the user setting, when the data flow of the mobile phone exceeds the preset value, the mobile phone automatically turns off the mobile data switch. Or according to the setting of the user, when the mobile phone is in the power saving mode, the mobile phone automatically turns off the mobile data switch. Or according to the setting of the mobile phone operating system, for example, in the 6.0 or 7.0 version of the android operating system, when the screen of the mobile phone is off but the whole mobile phone is not closed, the mobile phone enters a low power consumption (Doze) mode. When the mobile phone is in the low power consumption mode, the mobile phone automatically turns off the mobile data, even if the mobile data switch of the mobile phone is in an on state at the moment.

Optionally, the turning off of the mobile data of the mobile phone further includes turning on of a mobile data switch of the mobile phone, but the mobile phone does not establish a connection with the network side device through LTE. For example, as shown in fig. 6c, when the user turns on the mobile data switch and the Wireless-Fidelity (WI-FI) switch of the mobile phone 100 at the same time, and the mobile phone does not support the concurrence of the mobile data and the WI-FI data, the mobile phone will use the WI-FI network to perform data communication, and no longer use the mobile data to establish a connection with the network-side device. Namely, the AP sends the message of the mobile phone application to the WI-FI chip of the mobile phone, and the WI-FI chip of the mobile phone is sent to the server side of the mobile phone application through the WI-FI network. The AP does not send the message of the mobile phone application to the modem chip of the mobile phone any more, and then instructs the modem chip of the mobile phone to send the message to the network side equipment through the LTE network.

Specifically, after the mobile data on-off state of the mobile phone is changed, the mobile phone AP may actively send the current mobile data on-off state of the mobile phone to the modem chip of the mobile phone. The mobile AP may also passively wait for the modem chip of the mobile to obtain the current mobile data switch state of the mobile.

Further, after the modem chip of the mobile phone actively obtains or passively obtains the current mobile data switch state of the mobile phone from the AP of the mobile phone, if one or more conditions of complete machine restart, modem system restart, AP restart, and the like occur in the mobile phone, the modem chip of the mobile phone needs to obtain the current mobile data switch state of the mobile phone from the AP of the mobile phone again, or the AP of the mobile phone actively sends the current mobile data switch state of the mobile phone to the modem chip of the mobile phone.

S205, the mobile phone receives the paging message sent by the network side equipment.

After the mobile data of the mobile phone is closed, it can be known from the foregoing analysis that the EPS bearer established by the modem of the mobile phone and the network-side device is continuously reserved in step S201. When the network side device tries to send the paging message to the mobile phone, the mobile phone can still receive the paging message through the established EPS bearer.

S207, determining whether the paging message received by the mobile phone is used for data service.

Specifically, after receiving the paging message, the modem chip of the mobile phone parses the paging message. There are various methods for determining whether the paging message is used for the data service by the handset, and the method is not particularly limited herein. For example, the modem chip of the handset determines whether the value of the core network domain (CN-domain) of the paging message is PS. If the value of the paging message CN-domain is PS, the paging message represents that the network side device will initiate a data service, such as an internet service, to the mobile phone. If the value of the paging message CN-domain is CS, the paging message represents that the network side equipment initiates a common call service or a common short message service to the mobile phone.

If the paging message received by the handset is for data service, the method flow executes step S209. If the paging message received by the mobile phone is for a normal call or a short message service, step S213 is executed, and the mobile phone responds according to the existing LTE communication protocol.

S209, determine whether the mobile data of the mobile phone is closed. If the mobile data of the handset is turned off, step S211 is performed. If the mobile data of the handset is turned on, step S213 is executed, and the handset responds to the paging message according to the existing LTE communication protocol.

The execution order of step S207 and step S209 may be interchanged. That is, after the mobile phone receives the paging message, it can first determine whether the mobile data of the mobile phone is closed. If the mobile data of the mobile phone is closed, whether the paging message of the mobile phone is used for data service is further determined.

There are various methods for determining whether the mobile data of the mobile phone is turned off, and the method is not particularly limited herein. As an example, several determination methods are listed below.

1. And determining whether the mobile data switch state of the mobile phone is an off state. If the mobile data switch state of the mobile phone is the closing state, the mobile data of the mobile phone is closed. Further, if the mobile data switch state of the mobile phone is in an on state, whether the mobile phone is connected to an Access Point (AP) through WI-FI is further determined. If the mobile data switch state of the mobile phone is in an opening state and the mobile phone is connected to the AP through the WI-FI, the mobile data of the mobile phone is closed.

Specifically, there are various methods for determining the mobile data switch status and the WI-FI connection status of the mobile phone, and the method is not limited herein. For example, records of the mobile phone setting switches in the mobile phone AP are acquired to determine the current mobile data switch state and the WI-FI switch state of the mobile phone.

2. And monitoring the network connection type in the mobile phone and the state change of network connection and disconnection through registration broadcasting. To determine whether mobile data communications in the handset are turned on or off.

The following code is taken as an example. In an android operating system, the network connection state and the network connection type of a mobile phone are monitored through registration and broadcast.

S211, the mobile phone ignores the paging message and does not respond to the paging message.

According to the method, if the current PS domain access technology is LTE or 5G and the network connection state of the MOBILE type is not CONNECTED, the UE judges that the Modem side does not need to receive paging related to data service (not including IMS service), thereby avoiding unnecessary RRC establishment and saving standby power consumption.

Fig. 7 is a signaling flow diagram illustrating a UE stopping establishing an RRC connection with a network side device according to an embodiment of the present invention. As shown in fig. 7, after the mobile phone receives the paging message, because the mobile data of the mobile phone is already closed, the modem chip of the mobile phone no longer initiates an RRC connection request to the network side device according to the existing LTE communication protocol flow, and no longer establishes an RRC connection with the network side device, thereby reducing the power consumption of the mobile phone.

On the basis of the foregoing embodiment, if the user equipment shown in the foregoing embodiment supports LTE voice call (voice over LTE) and/or LTE video call (video over LTE), when the user equipment executes the method flow of the foregoing embodiment, it is necessary to avoid affecting the voice service or the video service of the user equipment. As shown in fig. 8, step S207 shown in fig. 5 specifically includes the following steps.

S2071, determine whether the value of CN-domain of the paging message received by the user equipment is PS.

If the value of CN-domain of the paging message received by the user equipment is PS, step S2072 is performed. If the value of CN-domain of the paging message received by the user equipment is CS, the user equipment responds to the paging message according to the existing LTE communication protocol.

S2072, determine whether the user equipment does not support IP Multimedia System (IMS) services or the IMS of the user equipment is unregistered.

If the user equipment does not support IMS, the user equipment does not support LTE voice call (voice over LTE) or LTE video call (video over LTE), and step S209 in fig. 5 is performed. If the IMS of the user equipment is not registered, indicating that the user equipment supports but does not turn on the volt or the vilte, step S209 in fig. 5 is performed. When the user equipment does not support the IMS or the IMS is not registered, the terminal cannot respond to the paging message of the volte or the vilte sent by the network side equipment. If the IMS of the user equipment is registered, the user equipment supports and starts the volte or vilte service. When the ue receives the paging message sent by the network side device, no matter whether the mobile data switch of the ue is turned on, the terminal responds to the paging message according to the existing LTE communication protocol, that is, step S213 is executed.

When the value of CN-domain of the paging message received by the user equipment is PS, according to the existing LTE communication protocol, the user equipment cannot distinguish whether the paging message represents a data service for internet access or a volte or vilte service. There is therefore a need to further determine whether the IMS registration status of a user equipment is unregistered or not supported. When the user equipment has started the voltage service or the video service, the user equipment responds to the paging message sent by the network side equipment according to the existing LTE communication protocol so as to avoid influencing the voltage service or the video service of the user equipment. With the development of the LTE communication protocol, if the user equipment can distinguish whether the paging message represents an internet-access data service or a volte or vilte service when receiving the paging message, the determination may be made according to the paging message without executing the method flow shown in fig. 8.

Specifically, when the IMS protocol stack of the user equipment is set in the AP of the user equipment, then the IMS registration status of the user equipment is recorded in the AP of the user equipment. The AP of the user equipment may actively send the IMS registration status to the modem chip of the terminal. Alternatively, the modem chip of the user equipment may also request the acquisition of the IMS registration status from the AP of the user equipment. And the modem chip determines whether the user equipment does not support IMS or the IMS is not registered according to the obtained IMS registration state.

When the IMS protocol stack of the user equipment is set in the modem of the user equipment, the IMS registration state of the user equipment is recorded in the modem of the user equipment. The modem chip may determine whether the user equipment does not support IMS or IMS unregister directly from the IMS registration status.
