In the prior art, according to the requirements of 3GPP TS23.402, a terminal supporting IMS/VoWiFi determines whether to switch a service from a wireless network to a WiFi network according to a built-in WiFi signal strength RSSI threshold after registering IMS through WiFi.

At this time, the wireless side antenna becomes available, and the power consumption is caused by continuously keeping the transceiving and the modulation and demodulation of the signals intangible, so that the battery endurance user experience is not ideal.

[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart of a control method according to an embodiment of the invention. The application processor of the terminal comprises a WiFi function module, the baseband processor of the terminal comprises a module for processing a wireless communication protocol, the terminal comprises a dual-mode or multi-mode terminal supporting an LTE/UMTS/GSM access technology, and the terminal supports services such as VoLTE, VoWiFi and IMS.
In step S1, the terminal evaluates the stability of the current WiFi link, where WiFi is a WiFi hotspot capable of providing instant voice communication services, where the instant voice communication services include voice call, video call, short message, data, call forwarding, and so on.
In step S2, the enabling state of the terminal wireless antenna is controlled according to the WiFi link stability evaluation result.
Referring to fig. 2, fig. 2 is a flowchart of a second control method according to the second embodiment of the invention. The application processor of the terminal comprises a WiFi function module, the baseband processor of the terminal comprises a modulation and demodulation module for processing a wireless communication protocol, the terminal comprises a dual-mode or multi-mode terminal supporting an LTE/UMTS/GSM access technology, and the terminal supports services such as VoLTE, VoWiFi and IMS.
In step S101, a terminal supporting VoWiFi registers a wireless network;
in step S102, the terminal selects a WiFi hotspot from a plurality of WiFi hotspots for connection;
in step S103, the terminal registers to the multimedia service core network through the WiFi link, it should be noted that, for a secure VoWiFi hotspot only deployed by an operator, it is not necessary to establish an IP tunnel to ensure security, the terminal may directly register to the multimedia service core network through such a WiFi hotspot, and when the terminal is in other situations, before registering to the multimedia service core network through the WiFi link, the terminal needs to establish an IP encryption tunnel with the multimedia service core network.
When the registration of the multimedia service core network through WiFi is successful, in step S104, a WiFi link quality evaluation mechanism is started.
In step S105, it is evaluated whether the WiFi link status is stable, wherein the WiFi link may be a VoWiFi link.
In step S106, when the WiFi link state is in a stable state, the terminal turns off the modem transceiving function of the wireless antenna or starts the discontinuous reception mechanism to enter the low-consumption mode, and returns to step S105 after entering the low-consumption mode for a preset time interval to evaluate whether the WiFi link state is stable.
When the WiFi link state is in an unstable state, in step S107, it is evaluated whether the terminal is in a low consumption mode.
When the terminal is in the low-consumption mode, in step S108, the terminal exits the low-consumption mode, that is, the terminal starts the transceiving function of the wireless antenna or exits the discontinuous reception mechanism, and after the terminal starts the transceiving function of the wireless antenna or exits the discontinuous reception mechanism, the terminal performs location update on the wireless network.
When the terminal is not in the low-consumption mode, i.e. the terminal starts the transceiving function of the wireless antenna or exits the discontinuous reception mechanism, the process returns to step S105 to evaluate whether the WiFi link state is stable.
Referring to fig. 3, fig. 3 is a flowchart of a control method according to an embodiment of the invention. The application processor of the terminal comprises a WiFi function module, the baseband processor of the terminal comprises a module for processing a wireless communication protocol Modem, the terminal comprises a dual-mode or multi-mode terminal supporting an LTE/UMTS/GSM access technology, and the terminal supports services such as VoLTE, VoWiFi and IMS.
In step S201, the terminal registers the multimedia service core network through the WiFi link, and for a secure VoWiFi hotspot only deployed by an operator, it is not necessary to establish an IP tunnel to ensure security, and the terminal may directly register the multimedia service core network through such a WiFi hotspot, and when the terminal is in other situations, before registering the terminal to the multimedia service core network through the WiFi link, the terminal needs to establish an IP encryption tunnel with the multimedia service core network.
In step S202, the terminal starts WiFi link evaluation, measures the RSSI of the current WiFi hotspot signal value, and obtains the RSSI value, for convenience, the RSSI value is represented by swift, where the WiFi link may be a VoWiFi link.
In step S203, the specific step of evaluating whether the measured current RSSI value is greater than or equal to a first preset value, where the first preset value is equal to the WiFi hotspot signal standard reaching threshold plus the hysteresis parameter, and the specific step of evaluating whether the measured current RSSI value is greater than or equal to the first preset value includes: the terminal sets two parameters, one is a WiFi hotspot signal standard threshold, for convenience of description, the WiFi hotspot signal standard threshold is represented by Sthrottle, the other is a hysteresis parameter for preventing the terminal from evaluating whether the WiFi hotspot signal reaches the standard ping-pong effect, Sw _ offset is used for representing the hysteresis parameter, and whether the measured value of the RSSI of the hotspot signal is greater than or equal to the sum of the WiFi hotspot signal standard threshold and the hysteresis parameter, namely whether Swifi is greater than or equal to Sthrottle + Sw _ offset is evaluated.
In step S204, when the measured value Swifi of the WiFi hotspot signal RSSI is greater than or equal to Sthrottle + Sw _ offset, the terminal sends a packet to the network. For example, if the terminal sets the Sthrottle to-80 dbm, Sw _ offset to 2, and the RSSI of the currently measured serving WiFi hotspot signal is-75 dbm, then Sthrottle + Sw _ offset is-80 +2 to-78 dbm, and then the RSSI > Sthrottle + Sw _ offset satisfies the condition, and the terminal sends the packet to the network. If not, the process returns to step S202. For example, if the RSSI of the currently measured service WiFi hotspot signal is-79 dbm, and the RSSI < Sthrottle + Sw _ offset is not satisfied, the procedure returns to step S202, measures the WiFi hotspot signal strength, and obtains the measurement value Swifi.
It should be noted that, since the signals have a small variation range (for example, the difference between the previous second and the next second is 2db), the ping-pong effect of the link quality evaluation can be effectively avoided by using the Sw _ offset parameter, a time interval is set between two measurements of the transmitted data packet, and the terminal interval time is set to Tmeas _ backoff in milliseconds. The specific steps of the terminal sending the data packet to the network include: the terminal sets two parameters, wherein one parameter is a preset number of data packets sent when the VoWiFi link quality is detected, the number is set as Nping, the other parameter is a threshold value of packet loss rate, the threshold value of the packet loss rate is set as Rthottle, the terminal sends the data packets with the preset number to a server of a multimedia service core network and calculates the packet loss rate of the whole RTT, and the calculated RTT packet loss rate is represented by Racketloss.
In step S205, the stability of the current WiFi link is evaluated according to whether calculated Rpacketloss is greater than or equal to a threshold value rthrittle of a packet loss rate. When the packet loss rate Rpacketloss is greater than or equal to Rthrottle, the stability of the current WiFi link is evaluated, and in step S206, the transceiving function of the terminal wireless antenna is turned off or the discontinuous reception mechanism of the terminal is started. For example, Nping is set to 30 and Rthlotle is set to 90%. The terminal sends 30 Data packets to an evolved Packet Data Gateway (ePDG), and if 28 epdgs respond, rpacketless is 28/30% > 93% > rthritle, and the stability of the current WiFi link is evaluated.
If the instability of the current WiFi link is evaluated, the process returns to step S204, for example, if the ePDG only responds to 25 packets, and Rpacketloss is 83% < rthrotlle, the instability of the current WiFi link is evaluated, and needs to be re-evaluated. It should be noted that the terminal further sets a time interval for retransmitting the preset number of packets to measure the packet loss rate, which is set as Tping _ backoff and is in unit of milliseconds, and after the time interval Tping _ backoff is reached, the terminal transmits the preset number of packets to the network to measure the packet loss rate again.
When the stability of the current WiFi link is evaluated, in step S206, the wireless antenna transceiving function of the terminal is turned off or the discontinuous reception mechanism of the terminal is enabled, the terminal sets a time period for evaluating the stability of the WiFi link next time, and starts a timer Tdetect of the time period, which is set in the terminal and has a unit of second.
Step S207: when the timer Tdetect is over, the process returns to step S202 to re-evaluate the stability of the current WiFi link.
Referring to fig. 4, fig. 4 is a functional block diagram of a terminal according to embodiment 4 of the present invention. The application processor of the terminal comprises a WiFi function module, the baseband processor of the terminal comprises a module for processing a wireless communication protocol, the terminal comprises a dual-mode or multi-mode terminal supporting LTE/UMTS/GSM access technology, and the terminal supports services such as VoLTE, VoWiFi, IMS, etc., the terminal 1 comprises an evaluation module 10 and a control module 11, and the function modules are described in detail below.
The evaluation module 10 evaluates the stability of the WiFi link currently establishing connection with the terminal; the WiFi is a WiFi hotspot capable of providing instant voice communication services. And the control module 11 controls the enabling state of the terminal wireless antenna according to the WiFi link stability evaluation result.
Referring to fig. 5, fig. 5 is a functional block diagram of a terminal according to embodiment 5 of the present invention. The terminal 1 comprises an evaluation module 10, a control module 11 and a connection module 12, and the detailed description of each functional module is provided below.
The connection module 12 registers a wireless network, selects a WiFi hotspot from a plurality of WiFi hotspots to connect, and registers the WiFi link to a multimedia service core network through the WiFi link after the WiFi link is successfully established, it should be noted that, for a secure VoWiFi hotspot only deployed by an operator, it is not necessary to ensure security by establishing an IP tunnel, the terminal can directly register the multimedia service core network through such a WiFi hotspot, and when the terminal is in other cases, before registering to the multimedia service core network through the WiFi link, the terminal needs to establish an IP encryption tunnel with the multimedia service core network.
When the multimedia service core network is successfully registered through WiFi, the evaluation module 10 evaluates whether the WiFi link state is stable, where the WiFi link may be a VoWiFi link.
The specific process of the evaluation module 10 evaluating whether the WiFi link status is stable includes the following steps.
The evaluation module 10 measures the RSSI of the current WiFi hotspot signal value to obtain an RSSI value, and for convenience of description, swift is used to represent the RSSI value, where the WiFi link may be a VoWiFi link.
The evaluation module 10 evaluates whether the measured current RSSI value is greater than or equal to a first preset value, where the first preset value is equal to the WiFi hotspot signal standard reaching threshold plus the hysteresis parameter, and the specific step of evaluating whether the measured current RSSI value is greater than or equal to the first preset value includes: the evaluation module 10 sets two parameters, one is a WiFi hotspot signal standard threshold, for convenience of description, the WiFi hotspot signal standard threshold is represented by Sthrottle, the other is a hysteresis parameter for preventing the terminal from evaluating whether the WiFi hotspot signal reaches the ping-pong effect, Sw _ offset represents the hysteresis parameter, and whether the measured value of the RSSI of the evaluation hotspot signal is greater than or equal to the sum of the WiFi hotspot signal standard threshold and the hysteresis parameter, that is, whether Swifi is greater than or equal to Sthrottle + Sw _ offset.
When the measured value Swifi of the WiFi hotspot signal RSSI is greater than or equal to Sthrottle + Sw _ offset, the evaluation module 10 sends a packet to the network. For example, if the terminal sets the Sthrottle to-80 dbm, Sw _ offset to 2, and the RSSI of the currently measured service WiFi hotspot signal is-75 dbm, then Sthrottle + Sw _ offset is-80 +2 to-78 dbm, and then the RSSI > Sthrottle + Sw _ offset satisfies the condition, and the evaluation module 10 sends the data packet to the network. If not, the evaluation module 10 re-measures the RSSI of the WiFi hotspot signal. For example, if the currently measured RSSI of the service WiFi hotspot signal is-79 dbm, then RSSI < Sthrottle + Sw _ offset, and the condition is not satisfied, the evaluation module 10 re-measures the WiFi hotspot signal strength and obtains the measured value Swifi.
It should be noted that, since the signals have a small variation range (for example, the difference between the previous second and the next second is 2db), the ping-pong effect of the link quality estimation can be effectively avoided by the Sw _ offset parameter. The time interval between the two measurements of the transmitted data packets is set by the evaluation module 10, and the interval time is set by the evaluation module 10 to Tmeas _ backoff in milliseconds. The specific steps of the evaluation module 10 sending a data packet to the network include: the evaluation module 10 sets two parameters, one is a preset number of data packets sent when detecting the WiFi link quality, and is set as Nping, the other is a threshold value of packet loss rate, and the threshold value of packet loss rate is set as Rthrottle, the evaluation module 10 sends the preset number of data packets to the server of the multimedia service core network and calculates the whole RTT packet loss rate, and rpacketlos represents the calculated RTT packet loss rate.
The evaluation module 10 evaluates the stability of the current WiFi link according to whether the calculated Rpacketloss is greater than or equal to a threshold Rthrottle of the packet loss rate. When the packet loss rate Rpacketloss is greater than or equal to Rthrottle, the stability of the current WiFi link is evaluated, and the control module 11 turns off the transceiving function of the terminal wireless antenna or starts the discontinuous receiving mechanism of the terminal. For example, Nping is set to 30 and Rthlotle is set to 90%. The evaluation module 10 sends 30 packets to an evolved Packet Data Gateway (ePDG), and if the ePDG responds to 28 packets, Rpacketloss 28/30 ═ 93% > rthrotlle, the stability of the current WiFi link is evaluated.
If the instability of the current WiFi link is evaluated, the evaluation module 10 evaluates the stability of the WiFi link again. For example, if the ePDG responds to only 25 packets, Rpacketloss is 83% < rthlotte, then the current WiFi link is evaluated for instability and needs to be re-evaluated. It should be noted that, the evaluation module 10 further sets a time interval for retransmitting the preset number of data packets to measure the packet loss rate, which is set as Tping _ backoff and is in unit of milliseconds, and after the time interval Tping _ backoff is reached, the evaluation module 10 transmits the preset number of data packets to the network to measure the packet loss rate again.
When the stability of the current WiFi link is evaluated, the control module 11 turns off the wireless antenna transceiving function of the terminal or enables the discontinuous reception mechanism of the terminal, the evaluation module 10 sets a time period for evaluating the stability of the WiFi link next time, and starts a timer Tdetect of the time period, the timer is set in the terminal, the unit is second, and when the timer Tdetect is overtime, the evaluation module 10 re-evaluates the stability of the current WiFi link.
When the WiFi link status is in an unstable status, the evaluation module 10 evaluates whether the terminal is in a low consumption mode. When the terminal is in the low-consumption mode, the control module 11 controls the terminal to exit the low-consumption mode, that is, the terminal starts the transceiving function of the wireless antenna or exits the discontinuous reception mechanism, and after the terminal starts the transceiving function of the wireless antenna or exits the discontinuous reception mechanism, the control module 11 updates the position of the wireless network. When the wireless terminal is not in the low-consumption mode, i.e. the terminal starts the transceiving function of the wireless antenna or exits the discontinuous reception mechanism, the evaluation module 10 evaluates whether the WiFi link state is stable.
The control method and the terminal provided by the invention can accurately evaluate the condition of the current WiFi link, automatically close the transceiving function of the wireless antenna or start a discontinuous receiving mechanism to reduce power consumption under the condition that the current WiFi link is kept stable, save electric quantity and bring better cruising user experience.
