Detailed Description

Embodiments of the present application include, but are not limited to, a user equipment and a power saving method thereof.

The technical scheme of this application can be applicable to communication fields such as 4G 5G mobile communication, thing networking communication, radar communication and satellite communication.

In order to make the objects, technical solutions and advantages of the present application more clear, the following takes a user equipment using 4G/5G mobile communication as an example, and the embodiments of the present application are further described in detail with reference to the accompanying drawings.

Fig. 1 shows a scenario in which a network side 200 of a 4G/5G network sends a packet to a user equipment 100.

When the ue 100 is in the standby state, if a spam message is received from the network side 200, the ue 100 may enter the awake state from the standby state. For example, as shown in fig. 2, the user equipment may frequently receive UDP messages with an IP address of 10.13.88.201 and a destination port number of 137, and no application uses the 137 port. The standby state or the awake state may be a state in which the system of the user equipment 100 enters the standby state or the awake state, for example, as shown in fig. 1, one of the manifestations of the user equipment 100 entering the awake state is that the screen of the user equipment 100 may be bright. The user device 100 is active even if the user device 100 is not bright. If the user equipment 100 frequently receives the spam message, it may cause additional power consumption of the user equipment 100 to be higher than that of the user equipment 100 in the standby state. As previously mentioned, the device sending the spam messages may send the spam messages by randomly selecting an IP address. In another embodiment of the present application, the spam message may be a broadcast message that is broadcast within the current IP subnet segment where the IP address of the user equipment 100 is located.

In order to solve the problem, in the embodiment of the present application, the IP address of the user equipment during communication between the user equipment 100 and the network side 200 may be changed when the user equipment 100 receives a large number of messages from the network side 200, so that when the device sending the spam messages randomly selects the IP address to send the spam messages, the IP address of the user equipment 100 may not be selected, and thus the problem of energy consumption caused by waking up of the user equipment 100 due to frequent receipt of the spam messages is solved. Specifically, the user equipment 100 may store an abnormal port list, where the abnormal port may be a port that is not used by an application program of the user equipment 100 in a standby state of the user equipment 100 or a port that is screened by the user equipment 100 from a received message log and that often receives a spam message; when the ue 100 is in the standby state, the ue 100 may monitor whether the abnormal port receives a packet and whether the number of the received packets meets a number threshold, and if the number threshold is met and the application program of the ue 100 does not use the abnormal port, the ue 100 may send an IP address change instruction corresponding to the current mobile access mode to the network 200, so that the IP address between the ue 100 and the network 200 changes. Since the IP address between the ue 100 and the network side 200 changes, or after the IP address between the ue 100 and the network side 200 changes, the current IP subnet segment of the ue 100 also changes, the ue 100 will not receive the spam message any more, so that the ue 100 will not frequently enter the wake-up state, and the energy saving effect can be achieved.

It is understood that the awake state or the standby state mentioned in the embodiments of the present Application may be that an AP side (Application Processor) of the user equipment is in the awake state or the standby state. For the user equipment, the operating system, the user interface and the application program of the user equipment 100 all run on the AP side; in contrast, the communication control program of the ue 100 is run on the BP side (Baseband Processor). Taking user equipment operating Android system (Android) as an example, the awakening state of the user equipment can be represented as one or more of the following conditions, the screen of the user equipment is kept fully bright, the user equipment is in a call, and data transmission between the user equipment and the network side is larger than a data quantity threshold value. In contrast, the standby state of the ue may be represented by one or more of the following situations, where the screen of the ue remains on the screen, the ue is in a non-call state, or there is only a small amount of data transmission between the ue and the network side, for example, the network side periodically sends a paging message to the ue to ensure that the call function of the ue is available, or the server of some applications sends an online detection message to the application of the ue through the network side to determine whether the application remains in the login state.

The user equipment in the embodiments of the present application is a terminal equipment providing voice and/or data connectivity to a user, for example, a common terminal equipment may include: in-vehicle devices, cell phones, tablets, laptops, palmtops, Mobile Internet Devices (MIDs), wearable devices (including, for example, smartwatches, smartbands, pedometers, etc.), personal digital assistants, portable media players, navigation devices, video game devices, set-top boxes, virtual reality and/or augmented reality devices, internet of things devices, industrial control devices, streaming media client devices, electronic books, reading devices, POS machines, and other devices.

In one embodiment of the present application, as shown in fig. 6, the handset 100 may configure the on/off option 1011 of the power saving service in the system setting of its own operating system. The user can turn on/off the energy saving service by clicking the on/off option 1011.

In one embodiment of the present application, if there is no option to provide power saving service on/off in the system settings of the handset 100, the power saving service may be configured such that the handset 100 may start the power saving service by itself while the handset 100 enters the standby state.

It is understood that step S501 is optional, that is, the energy saving service may be configured as a start item of the operating system of the mobile phone 100, and the energy saving service may be automatically turned on after the mobile phone 100 is started, without being manually turned on by the user.

S502: it is determined whether it is in a particular state.

If the mobile phone 100 is in a specific state, the process goes to S503, and the mobile phone 100 monitors whether the abnormal port receives a message; if not, the handset 100 returns to S502 and the handset 100 continues to listen whether the handset 100 enters a particular state. Step S502 may be implemented by the application processor included in the processor 110 of the mobile phone 100, that is, the AP side, executing the relevant program.

Specifically, in some embodiments of the present application, the specific state may include a standby state of the mobile phone 100, and the power saving service of the mobile phone 100 may determine that the mobile phone 100 is in the standby state if all or one of the following three conditions is met: 1. the screen of the mobile phone 100 is in a screen-off state; 2. the handset 100 is in a non-call state; 3. the handset 100 and the base station 200 have no data transmission. It is understood that the above three conditions for determining whether the mobile phone 100 is in a specific state are exemplary, and in the embodiment of the present application, other methods may be used to determine whether the mobile phone 100 is in a standby state. The following describes the method for determining the above three conditions by the mobile phone.

In some embodiments, as to whether the mobile phone 100 is in the screen-off state, the energy saving service may be determined by a power manager of a framework layer of a software system of the mobile phone 100, and the power manager of the mobile phone 100 may send the screen of the mobile phone 100 to enter the screen-on state and the screen-off state in a system broadcast manner, that is, each time the mobile phone 100 enters the screen-on state or the screen-off state, the software system of the mobile phone 100 sends out a corresponding system broadcast. The mobile phone 100 may register a receiver for receiving the system broadcasts in the on-screen state and the off-screen state, that is, a receiving program, in the energy saving service, and the receiving program may monitor the system broadcasts in the on-screen state and the off-screen state in real time, and notify the energy saving service after receiving the system broadcasts in the on-screen state or the off-screen state.

In some embodiments, for whether the mobile phone 100 is in a non-call state, the energy saving service may determine, by a communication manager of a framework layer of a software system of the mobile phone 100, that the communication manager of the mobile phone 100 is configured with a method for acquiring whether a current state of a call service of the mobile phone 100 is in a call state, where the method may indicate that the call service of the mobile phone 100 is in a call by returning yes, indicate that the call service of the mobile phone 100 is in a non-call by returning no, and the energy saving service may determine, by the communication manager, whether the mobile phone 100 is in a non-call state by calling the method.

In some embodiments, whether there is data transmission between the handset 100 and the base station 200, the energy saving service may determine through a traffic manager of a framework layer of a software system of the handset 100, and the traffic manager of the handset 100 may detect a current amount of data received by the handset 100 from the base station 200, for example, where the amount of data may be a total number of bytes received by the handset 100 from the base station 200. The energy saving service may continuously detect the amount of data received by the mobile phone 100 within a preset time period, and when the amount of data received by the mobile phone 100 is greater than the threshold of the amount of data within the preset time period, the energy saving service determines that there is data transmission between the mobile phone 100 and the base station 200, otherwise, the energy saving service determines that there is no data transmission between the mobile phone 100 and the base station 200. For example, the preset time period may be 10s, the data amount threshold may be 1MB (megabyte ), and in the case where the energy saving service detects that the number of data received by the handset 100 at 10s is greater than 1MB, the handset 100 confirms that there is data transmission with the base station 200.

It is to be understood that, in the above step S502, the specific state of the mobile phone 100 may include that the screen of the user equipment keeps on screen but the application program of the user equipment is in a use state, for example, the user swipes the card into a subway station by means of NFC (Near Field Communication), and at this time, the screen of the user equipment keeps on screen.

It can be understood that step S502 may also be optional, that is, the mobile phone 100 may directly monitor whether the abnormal port of the mobile phone 100 receives the spam message without determining whether the current state is the specific state.

S503: and monitoring whether the number of the messages received by the abnormal port exceeds a message number threshold value or not in the abnormal ports listed in the abnormal port list.

Steps S503 to S506 may be executed by the baseband processor included in the processor 110 of the mobile phone 100, that is, on the BP side, and implemented by the baseband processor executing the relevant program, and the baseband processor does not return the results of steps S503 to S506 to the application processor, so that the application processor is prevented from entering the wake-up state after receiving the results of the baseband processor, and the energy consumption of the mobile phone 100 can be reduced.

It is understood that, in some embodiments of the present application, the abnormal port list may be preset in the memory of the mobile phone 100, and the abnormal port in the abnormal port list may be a port that is not used by the application program of the mobile phone 100 in the standby state of the mobile phone 100 or a port that is screened by the mobile phone 100 from the received message log and that will often receive spam messages.

If the energy saving service monitors that the number of the messages received by the mobile phone 100 through the abnormal port exceeds the threshold value of the number of the messages, it indicates that the probability that the mobile phone 100 is attacked by the spam messages is high, so when the mobile phone 100 confirms that the number of the messages received through the abnormal port exceeds the threshold value of the number of the messages, the step S504 is entered, and whether an application program uses the abnormal port is further confirmed; otherwise, the step S503 is continuously executed to continuously monitor the number of the messages received through the abnormal port.

In the embodiment of the present application, table 1 shows an abnormal port list used for the energy saving service to determine whether an abnormal port receives a message. Taking the rule with sequence number 1 as an example, the rule includes: the port 137 and the message type are UDP (User Datagram Protocol), and the energy saving service monitors whether the port 137 receives a UDP message according to a rule of the sequence number 1.

The message quantity threshold is used for the energy saving service to determine whether the number of messages received by the abnormal port is greater than the message quantity threshold within a preset time period, if so, the step S504 is executed, and the energy saving service further determines whether an application program uses the abnormal port. If so, the monitoring continues. For example, in the embodiment of the present application, the preset time period may be 10s (seconds), the threshold of the number of packets may be 1000, and after the energy saving service determination port 137 receives 1200 UDP packets within 10s, the energy saving service may determine that the number of UDP packets received through the abnormal port 137 is greater than the threshold of the number of packets. It is understood that only 3 rules are listed in table 1 for illustration, and the user can set any number of rules in table 1 according to practical situations, which is not limited herein.

Serial number	Port(s)	Type of message
			1	137	UDP
2	9	UDP
			3	9	TCP
…	…	…

TABLE 1

S504: and judging whether an application program uses the abnormal port or not.

If yes, indicating that the message received by the port is a normal service message, returning to step S503, and the mobile phone 100 continues to monitor whether the message received by the abnormal port exceeds the message quantity threshold; if not, it indicates that the message received by the port is a spam message, the mobile phone 100 proceeds to step S505, and the mobile phone 100 determines the type of the current mobile access mode.

Here, the energy saving service may execute an instruction for querying port information, for example, the energy saving service executes an instruction for querying information of the port 137 and the port 9, and after the instruction is executed, the energy saving service may obtain information of the port 137 and the port 9, including: the message type, the IP address of the access port, port 137 and port 9, and the User Identification (UID) of the corresponding application. The user identification may correspond one-to-one to the applications running in the handset 100. As shown in table 2, for port 9, the application with UID u0_ a34 is using the port, and the energy saving service can be further based on UID: u0_ a34 determines the name of the application; however, for the port 137, the energy saving service does not find that the application uses the port, and therefore, the process proceeds to step S505.

It is understood that the port information in table 2 is exemplary, and in the embodiment of the present application, the port information obtained by the energy saving service executing the instruction for querying the port information may further include more information, for example, an IP address of the local location of the mobile phone 100, an access right, and the like.

TABLE 2

S505: the current mobile access mode of the handset 100 is determined.

Since the mobile phone 100 can execute different IP address change commands in different mobile access modes, it is necessary to determine the current mobile access mode of the mobile phone 100.

Here, the mobile Access Technology (RAT) is a connection method of the wireless communication network of the mobile phone 100, and in the embodiment of the present application, the mobile Access mode of the mobile phone 100 mainly includes three types, namely NR SA, NSA and LTE.

The type of mobile access mode may be stored on the BP side, i.e. the baseband processor side, of the handset 100. For the current mobile access mode of the mobile phone 100, the energy saving service may be determined by a baseband processor of the mobile phone 100, the baseband processor of the mobile phone 100 is configured with a method for accessing the type of the current mobile access mode of the mobile phone 100, and the energy saving service may determine the type of the current mobile access mode of the mobile phone 100 according to a return value of the method. For example, when the method returns TYPE _ LTE, it indicates that the current mobile access mode of the mobile phone 100 is LTE 4G; when the method returns TYPE _ NSA, it indicates that the current mobile access mode of the mobile phone 100 is NSA; when the method returns TYPE _ NR, it indicates that the current mobile access mode of the mobile phone 100 is NR SA. It is to be understood that the above return values TYPE _ LTE, TYPE _ NSA, and TYPE _ NR are exemplary, and in the embodiments of the present application, other return values may be used to represent NR SA, NSA, and LTE.

S506: and executing an IP address change instruction corresponding to the current mobile access mode.

As shown in fig. 7, when the mobile phone 100 determines that the abnormal port receives the spam message, if the current mobile access mode of the mobile phone 100 is NSA or LTE, the mobile phone 100 may change the current IP address of the mobile phone 100 by sending signaling for deactivating/activating PDN (Public Data Network) and detaching/attaching to the base station 200. It is understood that after the handset 100 executes the above command, the connection with the base station 200 may be re-established, and then the base station 200 may assign a new IP address to the handset 100 to implement the IP address change.

In some embodiments, as shown in fig. 8, the process of detaching/attaching the instruction includes: for the handset 100 that maintains the connection state with the base station 200, the energy saving service may also send a detach request (detach request) to the base station 200 through the baseband processor of the handset 100; after receiving the detach request, the base station 200 returns a detach accept response (detach accept) to the mobile phone 100, disconnects the connection with the mobile phone 100, and switches the mobile phone 100 to the off-line state.

Then, the mobile phone 100 may send a connection establishment request to the base station 200 to reestablish the connection with the base station 200, and then send an attach request (attach request) to the base station 200 to reattach the network; after receiving the attach request, the base station 200 returns an attach accept response (attach accept) to the mobile phone 100, and after the base station 200 completes the attach (attach complete), the base station 200 establishes a connection with the mobile phone 100.

In some embodiments, as shown in fig. 9, the process of deactivating/activating instructions for a PDN includes: for the handset 100 that maintains the connection state with the base station 200, the energy saving service may also send a PDN disconnection request (PDN disconnect request) to the base station 200 through a baseband processor of the handset 100; after receiving the PDN deactivation request, the base station 200 returns a PDN deactivation request (deactivation eps bearer context request) to the mobile phone 100; after the mobile phone 100 returns a response (deactivation eps bearer context accept) to the base station 200 to receive the PDN connection, the base station 200 disconnects the PDN connection with the mobile phone 100.

Thereafter, the handset 100 may send a connection PDN request (PDN connectivity request) to the base station 200; after receiving the PDN activation request, the base station 200 returns an PDN activation request (activate default eps bearer context request) to the mobile phone 100; after the mobile phone 100 returns an activate PDN request accept response (activate default eps bearer context accept) to the base station 200, the base station 200 establishes a PDN connection with the mobile phone 100.

It is to be understood that, in some embodiments, as shown in fig. 7, in a case that the current mobile access mode of the handset 100 is NSA or LTE, the handset 100 may further change the current IP address of the handset 100 by turning on the flight mode and then turning off the flight mode. The operation of turning off/on the flight mode may achieve the same effect as the operation of deactivating/activating a PDN.

It can be understood that, as shown in fig. 7, in the case that the current mobile access mode of the handset 100 is NR SA, the handset 100 may change the current IP address of the handset 100 by sending a PDU (Protocol Data Unit) session release signaling to the base station 200

In some embodiments, as shown in fig. 10, the process of instructing PDU session release includes: for the mobile phone 100 that maintains the connection state with the base station 200, the energy saving service may also send a PDU session release request msg to the base station 200 through a baseband processor of the mobile phone 100; after receiving the PDU session release request, the base station 200 returns a PDU session release command msg to the mobile phone 100, and meanwhile, after the base station 200 returns a PDU session release complete msg to the mobile phone 100, the base station 200 disconnects the PDU session with the mobile phone 100.

Then, the mobile phone 100 may send a PDU session establishment request (PDU session establishment request) to the base station 200; after receiving the PDU session establishment request, the base station 200 returns a response (PDU session acknowledgement) for receiving the PDU session establishment to the mobile phone 100, and the base station 200 establishes a PDU session with the mobile phone 100.

Here, by the method in step S506, the mobile phone 100 can change the current IP address of the mobile phone 100, so that the port that receives the message but does not receive the message any more without using the application program, thereby saving energy of the mobile phone 100, and meanwhile, after the current IP address of the mobile phone 100 is changed, the application program run by the mobile phone 100 can establish a connection with the server of the application program again through the changed IP address, and the running of the application program is not affected.

It can be understood that, no matter the current mobile access mode of the mobile phone 100 is NSA, LTE or NR SA, after the mobile phone 100 executes the IP address change instruction corresponding to the current mobile access mode, if the mobile phone 100 still receives the spam message, the mobile phone 100 may further retry according to a preset retry interval, for example: and 10s, repeatedly executing the IP address change instruction, and if the repeated times exceed a preset retry threshold, for example: the method of steps S501 to S506 is stopped 10 times. So as to prevent the mobile phone 100 and the base station 200 from being switched between the connected state and the disconnected state all the time, and further affect the normal function of the mobile phone 100, for example, the mobile phone 100 cannot answer the call.

After the energy saving method of the embodiment of the present application is explained through steps S501 to S506, an energy saving scheme in another embodiment of the present application is described below through fig. 11. It will be appreciated that the power saving scheme depicted in fig. 11 may also be implemented by the baseband processor of the processor 110 of the handset 100 executing the associated program. The difference from the power saving scheme depicted in fig. 5 is that the power saving scheme depicted in fig. 11 may operate only on the BP side of the handset 100, and includes:

s1101: determining whether the number of the messages received by the abnormal port exceeds a message number threshold value or not in the abnormal ports listed in the abnormal port list

S1101 is the same as S503, if the energy saving service of the mobile phone 100 detects that the number of messages received by the mobile phone 100 through the abnormal port exceeds the threshold of the number of messages, the process goes to step S1102 to further determine whether an application program uses the abnormal port; otherwise, the step S1101 is continuously executed to continuously monitor the number of the messages received through the abnormal port.

S1102: and judging whether an application program uses the abnormal port or not.

S1102 is the same as S504, and if yes, it indicates that the packet received by the port is a normal service packet, the process returns to step S1101, and the mobile phone 100 continues to monitor whether the packet received by the abnormal port exceeds the packet quantity threshold; if not, it indicates that the message received by the port is a spam message, the mobile phone 100 proceeds to step S1103, and the mobile phone 100 executes an IP address change instruction corresponding to the current mobile access mode.

S1103: and executing an IP address change instruction corresponding to the current mobile access mode.

Here, S1103 is the same as S505 and S506, and the mobile phone 100 executes the corresponding IP address change command in response to the current mobile access mode being NSA, LTE or SA.
