Background technique

With the development of communication technology, the emergence of the fourth generation mobile communication (4G) network has met the demand for data services.

The data services of Long Term Evolution (LTE) and 5th-Generation (5G) have always been online. For example, when the UE attaches on LTE, it will request to establish a Packet Data Network (PDN) connection by default. The user equipment and the network side device maintain a long data connection, so that the data service of the user equipment (UE) maintains the Internet Protocol (IP) online for a long time. In other words, 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 remain connected (Always on IP connectivity).

After the UE closes the mobile data switch, since the LTE or 5G mobile data service has the characteristics of being always online, there is still a situation of data interaction between the communication protocol layer UE and the network side device. After receiving various data packets of the network side device, the UE still responds to the data packet, causing the UE to consume power.

2 is a schematic diagram of an LTE network architecture 100. 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 equipment, where the network side equipment includes, but is not limited to, an evolved UMTS Terrestrial Radio Access Network (E-UTRAN) 104, an evolution An Evolved Packet Core (EPC) 110, and an operator's Internet Protocol (IP) service 122. EPS can be interconnected 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 can be extended to networks that provide circuit switched services.

The E-UTRAN includes an evolved Node B (eNB) 106, other eNBs 108, and a Multi-cell/Multicast Coordination Entity (MCE) 128. The eNB 106 provides protocol termination towards the user plane and control plane of the UE 102. The eNB 106 can 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. The eNB 106 provides the UE 110 with an access point to the EPC 102. Examples of UEs 102 include cellular telephones, smart phones, Session Initiation Protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (eg, , MP3 player), camera, game console, tablet device, or any other similar feature device. UE 102 may also be referred to by those skilled in the art as a mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, Mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other suitable term.

The eNB 106 is connected to the EPC 110. The EPC 110 may include a Mobility Management Entity (MME) 112, a Home Subscriber Server (HSS) 120, other MMEs 114, a Serving Gateway 116, a Multimedia Broadcast Multicast Service (MBMS) Gateway 124, and a Broadcast Multicast Service Center (BM-SC). 126, and a Packet Data Network (PDN) gateway 118. The MME 112 is a control node that handles signaling between the UE 102 and the EPC 110. In general, MME 112 provides bearer and connection management. All user IP packets are passed through the Serving Gateway 116, which itself is connected to the PDN Gateway 118. The PDN Gateway 118 provides IP address allocation and other functions for the UE. PDN gateway 118 and BM-SC 126 are connected to IP service 122. IP services 122 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS), a PS Streaming Service (PSS), and/or other IP services.

In the actual communication process, the UE needs to be attached to an Evolved Packet System (EPS) deployed by an operator when acquiring the LTE service. In the EPS attach process, a default EPS bearer, that is, a user bearer with default security performance, is established between the terminal, the access network, the core network, and the external packet data network (PDN). Of course, other proprietary bearers can also be established according to the needs of the user's business, that is, User bearers with special security features and transmission performance. All data packets of the LTE user will be transmitted uplink or downlink on the established EPS bearer channel.

Currently, UE devices that support cellular communication and a user interface (UI) are generally classified into a modem system and an application processor (AP) system. The modem system is the baseband subsystem responsible for implementing the protocol stack for cellular communications. An application processor system is an application processing subsystem that is responsible for running drivers, kernels, middleware, and applications. The networked application of the application processor system communicates with and receives communication through the modem system and the network side device. The modem system and the application processor system can sleep independently.

The user opens the mobile data switch of the UE on the user interface (the state of the mobile data opening of the UE is changed from off to on), and the UE establishes an EPS bearer with the network side device. After the user closes the mobile data switch of the UE on the user interface (the state of the mobile data of the UE is changed from open to closed), the UE does not remove the existing EPS bearer. Only the IP connection is removed from the AP system. The networked application in the AP system is disconnected from the network-side device. Therefore, IP packets are not sent to the network-side device. However, the UE's modem system still maintains the EPS bearer. The server of the network side device still considers that the UE's networked application is online until its heartbeat cannot be synchronized or the aging timer of the IP connection expires. 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 channel.

3 is a schematic flowchart of a communication protocol for establishing a Radio Resource Control (RRC) connection between a UE and a network side device. As shown in FIG. 3, in the LTE communication protocol procedure, the UE and the network side device evolved Node B (eNB) perform communication. After the UE establishes an EPS bearer with the network side device, the network side device sends an RRC paging message to the UE side. After receiving the RRC Paging message, the UE responds to the RRC Paging message. The UE initiates an RRC connection request to the network side device, and after receiving the RRC connection request sent by the UE, the network side device establishes an RRC connection with the UE. After the RRC connection established between the UE and the network side device is no longer needed, the network side device sends an RRC Connection Release message to the UE, and after receiving the RRC connection release message, the UE releases the RRC with the network side device. connection.

Since the modem system of the UE still maintains the EPS bearer, the network side device still attempts to send a packet to the UE. For example, the UE receives an RRC paging message sent by the network side device. If the value of the core domain (CN-domain) field of the message is ps, the UE establishes an RRC connection with the network side device. . Usually, after the RRC connection is successfully established, it will last for 10 seconds. The IP packet received by the modem is not forwarded to the AP because the data switch of the UE is disabled. Modem is awakened to RRC establishment and continuous power consumption is not necessary for the UE.

In order to solve the situation that the UE can still receive the data packet sent by the network side device after the mobile data switch of the UE is closed, and the power consumption of the UE is wasted, the embodiment of the present invention provides some solutions.

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

S101. The UE receives a paging message sent by the network side device.

Since the LTE data service has the characteristics of being always online, after the user equipment and the network side device supporting the LTE or 5G mobile data communication successfully establish an EPS bearer, the network side device can be sent through the EPS bearer. Call the message to the UE.

S103. When the paging message is used to identify a data service, and the mobile data of the UE is turned off, the paging message is ignored.

After receiving the paging message sent by the network side device, the UE parses the paging message. When the paging message is used to identify the data service, the UE will initiate an RRC connection request to the network side device according to the existing LTE communication protocol, and the RRC connection is established between the request and the network side device, so that the UE performs subsequent data services, such as Application messaging service.

FIG. 5 is a flowchart of a method for another data transmission method according to an embodiment of the present invention. The execution body of the method flow is user equipment supporting LTE or 5G mobile data communication. Specifically, the execution body of the method flow is a modem chip in 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 sent by the network side device. In the following, taking the user equipment as the mobile phone as an example, the specific implementation process of the solution is illustrated, as shown in FIG. 5 .

S201: The mobile phone and the network side device successfully establish an EPS bearer.

The mobile phone shown in Figures 6a-6c is a terminal supporting LTE. As shown in FIG. 6a, the user clicks the mobile data switch on the switch setting interface of the mobile phone 100, and the mobile data switch changes from the non-highlight 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 that the status information of the current mobile data switch is on. The mobile phone establishes a communication connection with the network side device through the LTE service, and establishes an EPS bearer with the network side device when the UE attaches on the LTE network.

S203, the mobile data of the mobile phone is turned off.

As shown in FIG. 6b, the user clicks the mobile data switch on the switch setting interface of the mobile phone 100 again, and the mobile data switch changes 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 turned off, the application processor in the mobile phone records the status information of the current mobile data switch to be closed again. The application processor of the mobile phone locally removes the IP connection, and no longer instructs the modem to send an IP packet to the network side device.

Alternatively, the mobile data switch of the mobile phone may be turned off 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 user settings, when the mobile phone is in the power saving mode, the mobile phone automatically turns off the mobile data switch. Or according to the settings of the mobile phone operating system, such as in the Android operating system 6.0 or 7.0 version, when the mobile phone screen is off but the whole machine is not turned off, the mobile phone enters a low power (Doze) mode. When the phone is in low power mode, the phone automatically turns off the mobile data even if the mobile data switch of the phone is turned on.

Optionally, the mobile data of the mobile phone is turned off, and the mobile data switch of the mobile phone is turned on, but the mobile phone does not establish a connection with the network side device through the LTE. For example, as shown in FIG. 6c, the user simultaneously turns on the mobile data switch of the mobile phone 100 and Wireless-Fidelity (WI-FI) switch, when the mobile phone does not support mobile data and WI-FI data concurrency, the mobile phone will use the WI-FI network for data communication instead of using mobile data and network side devices. connection. That is, the AP sends the message of the mobile 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 application through the WI-FI network. The AP no longer sends the packet of the mobile application to the modem chip of the mobile phone, and then indicates that the modem chip of the mobile phone is sent to the network side device through the LTE network.

Specifically, after the mobile data switch status of the mobile phone changes, the mobile phone AP can actively send the current mobile data switch status of the mobile phone to the modem chip of the mobile phone. The mobile phone AP can also passively wait for the modem chip of the mobile phone to obtain the current mobile data switch state of the mobile phone.

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 the mobile phone has one or more situations such as restarting the whole machine, restarting the modem system, and restarting the AP, the mobile phone is The modem chip needs to obtain the current mobile data switch status of the mobile phone from the AP of the mobile phone again, or the mobile phone AP actively sends the current mobile data switch status of the mobile phone to the modem chip of the mobile phone.

S205. The mobile phone receives a paging message sent by the network side device.

After the mobile phone data is closed, according to the foregoing analysis, the modem of the mobile phone and the EPS bearer established by the network side device are retained in step S201. When the network side device attempts to send a paging message to the mobile phone, the mobile phone can still receive the paging message through the established EPS bearer.

S207. Determine whether a paging message received by the mobile phone is used for data services.

Specifically, after receiving the paging message, the modem chip of the mobile phone parses the paging message. There are various methods for determining whether a paging message is used for a data service, and is not specifically limited herein. For example, the modem chip of the mobile phone determines whether the value of the core domain (CN-domain) of the paging message is PS. If the value of the paging message CN-domain is PS, the paging message indicates 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 indicates that the network side device will initiate an ordinary call service or a normal short message service to the mobile phone.

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

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

The order of execution of step S207 and step S209 can 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 turned off. If the mobile data of the mobile phone is turned off, it is further determined whether the paging message of the mobile phone is used for data services.

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

1. Determine if the mobile data switch status of the mobile phone is off. If the mobile phone's mobile data switch status is When the status is off, the mobile data of the mobile phone has been closed. Further, if the mobile data switch state of the mobile phone is the on state, it is further determined whether the mobile phone is connected to the access point (AP) through the WI-FI. If the mobile data switch status of the mobile phone is on and the mobile phone is connected to the AP through WI-FI, it means that the mobile data of the mobile phone has been turned off.

Specifically, there are various methods for determining the mobile data switch state of the mobile phone and the WI-FI connection state, which are not specifically limited herein. For example, obtaining a record of each setting switch of the mobile phone in the mobile phone AP to determine the current mobile data switch state of the mobile phone and the WI-FI switch state.

2. By registering the broadcast, monitoring the type of network connection in the mobile phone, and the status of the network connection and disconnection. Determine if mobile data communication in the phone is turned on or off.

Take the following code as an example. In the Android operating system, the network connection status of the mobile phone and the type of network connection are monitored by registering the broadcast.

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

According to the foregoing method, the UE determines that if the current PS domain access technology is LTE or 5G, and the network connection status of the MOBILE type is not CONNECTED, the modem side may not need to receive paging related to the data service (excluding the IMS service) at this time. , thereby avoiding unnecessary RRC establishment and saving standby power consumption.

FIG. 7 is a schematic flowchart of signaling that the UE stops 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, since the mobile phone mobile data has been 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 is no longer associated with The network side device establishes an RRC connection, thereby reducing power consumption of the mobile phone.

On the basis of the foregoing embodiment, if the user equipment shown in the foregoing embodiment supports both voice over LTE (volte) and/or LTE video call (video over LTE), the user equipment performs the above implementation. In the method flow of the example, it is necessary to avoid the volte service or the vilte service that affects 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 the CN-domain of the paging message received by the user equipment is PS.

If the value of the CN-domain of the paging message received by the user equipment is PS, step S2072 is performed. If the value of the 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 the IP Multimedia Subsystem (IMS) service or the IMS of the user equipment is not registered.

If the user equipment does not support IMS, the user equipment does not support voice over LTE (volte) or LTE video call (video over LTE, vitel), and step S209 in FIG. 5 is performed. If the IMS of the user equipment is not registered, it indicates that the user equipment supports but does not turn on volte or vilte, and step S209 in FIG. 5 is performed. When the user equipment does not support IMS or the IMS is not registered, the terminal cannot respond to the volte or vilte paging message delivered by the network side device. If the IMS of the user equipment is registered, the user equipment support is supported and the volte or vilte service is turned on. When the user equipment receives the paging message sent by the network side device, regardless of whether the mobile data switch of the user equipment is enabled, the terminal responds to the paging message according to the existing LTE communication protocol, that is, step S213 is performed.

When the value of the 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 the data service of the Internet, or the volte or vilte service. Therefore, it is necessary to further determine whether the IMS registration status of the user equipment is unregistered or not supported. When the user equipment has enabled the volte service or the vilte service, the user equipment responds to the paging message sent by the network side device according to the existing LTE communication protocol, so as to avoid affecting the volte service or the vilte service of the user equipment. With the development of the LTE communication protocol, if the user equipment can distinguish whether the paging message represents the data service on the Internet or the volte or vilte service when receiving the paging message, the user equipment can determine according to the paging message, and does not need to execute the map. The method flow shown in 8.

Specifically, when the IMS protocol stack of the user equipment is set in the AP of the user equipment, the IMS registration status of the user equipment is recorded in the AP of the user equipment. The AP of the user equipment can 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 AP of the user equipment to obtain the IMS registration status. The modem chip determines whether the user equipment does not support IMS or the IMS is not registered according to the acquired IMS registration status.

When the IMS protocol stack of the user equipment is set in the modem of the user equipment, the IMS registration status of the user equipment is recorded in the modem of the user equipment. The modem chip can directly determine whether the user equipment does not support IMS or the IMS is not registered according to the IMS registration status.
