Detailed Description
The following describes the embodiments in further detail with reference to the accompanying drawings.
Example one
An embodiment of the present invention provides a method for switching a network, as shown in fig. 1, where the method includes:
s101, when a terminal carries out an IP-based call service through a first wireless network, detecting a service quality parameter for carrying out the call service; wherein the first wireless network is unable to allocate a dedicated bearer channel;
when a terminal establishes communication with another terminal through a first wireless network and performs a call service, the first wireless network used by the terminal cannot allocate a dedicated bearer channel for the currently performed communication service, such as a WLAN network, a World Interoperability for Microwave Access (wmax) network, a High Rate Packet Data (HRPD) network, and a wireless network that is not controlled by its core network, so that when the terminal performs the call service, the first wireless network cannot provide quality assurance of air interface service for the terminal. The dedicated bearer channel may also be referred to as a dedicated traffic channel, and is a channel for guaranteeing delay and rate requirements of voice, video, and the like through a dedicated resource. Such as: when the terminal carries out communication service based on VoWifi, the terminal is accessed to a core network of an operator through a Wifi network, the core network of the operator cannot carry out broadband equal-air-interface setting on the WiFi network, and therefore the WiFi network cannot allocate a special bearing channel or a special service channel to the terminal, and QoS guarantee required by the service cannot be provided. Here, the first wireless network is exemplified as a wireless network that is not controlled by its own core network, for example: when two SIM cards of operator 1 and operator 2 exist in the terminal: when a user carries out a communication service through the SIM card 2 by means of the network of the operator 1, the terminal is in communication connection with the network of the operator 1 through the SIM card 2, and when the air interface resources are insufficient, the core network of the operator 1 cannot allocate air interface resources for the SIM card 2, so that the network corresponding to the current wireless network cannot allocate a dedicated bearer channel to carry out QoS guarantee on the communication service.
Here, the call service may include a voice call service, a video call service, and the like, which require a service quality with a low bit error rate and a low time delay and have a relatively high requirement, and when the service quality cannot be guaranteed during such a service, the quality of the current call service may be seriously affected, a communication connection between terminals may exist, but the situations of distortion, non-reception, and the like of voice, images, and the like of a call occur, and at this time, the call experience of a user is not good.
When the terminal carries out the call service through the first wireless network, the current service quality parameter is detected, and the service quality parameter can reflect whether the current call service is normally carried out or not. When the network environment of the terminal for performing the call service changes, for example: a terminal A for carrying out the call service is added in a network corresponding to the first wireless network, and at the moment, the bandwidth used by the terminal for carrying out the call service after the terminal A joins is influenced, so that the QoS of the call service carried out by the terminal is influenced; for another example: when the user moves back and forth while carrying out the call service, the distance between the terminal and the signal source is changed, and the received signal strength of the first wireless network is affected, thereby affecting the QoS of the ongoing call service.
In an embodiment of the present invention, the quality of service parameter includes at least one of: call bandwidth, error rate, time delay, JITTER, etc. When the value of any one of the above-mentioned quality of service parameters changes, the quality of the current call service may be affected. Here, the qos parameter is a relevant parameter or characteristic that can be used to characterize the qos of the service, and is not limited to the qos parameter.
S102, matching the service quality parameters of the call service with a preset service quality switching strategy;
before this step, the method further comprises: and setting the preset service quality switching strategy according to the service quality parameters. The preset service quality call strategy comprises one or more rules for determining that the service quality parameters do not meet the service quality of the call service.
Here, the preset qos switching policy is set according to the qos parameter, and the preset qos switching policy includes at least one of: the call bandwidth is smaller than a preset call bandwidth threshold; the error rate is greater than a preset error rate threshold value; the time delay is greater than a preset time delay threshold value; JITTER is greater than a preset JITTER threshold. Here, the qos switching policy may include one or more rules as described above, and whether the corresponding qos parameter satisfies the rule included in the qos switching policy is determined according to the number of rules included in the qos switching policy. The call bandwidth threshold, the error rate threshold, the delay threshold and the JITTER threshold can be set according to the requirement of the user on the service quality.
And matching the service quality parameter with a preset service quality switching strategy, and when the service quality parameter meets a rule corresponding to the service quality parameter in the service quality conversation strategy, indicating that the service quality parameter is matched with the preset service quality switching strategy, and switching the network which needs to communicate with the terminal at present. Here, the quality of service parameter not matching the preset quality of service switching policy includes one or more of the quality of service parameters not satisfying a corresponding rule; and determining that the service quality parameters are not matched with the preset service quality switching strategy only when all the service quality parameters do not meet the corresponding rules under the condition that the service quality parameters are matched with the preset service quality switching strategy when one parameter meets the corresponding rules, which indicates that the network which does not need to communicate with the terminal is not switched.
S103, when the service quality parameter of the call service is matched with the preset service quality switching strategy, switching from the first wireless network to a second wireless network, and continuing the call service based on the second wireless network.
And when the service quality parameter of the call service is matched with the service quality switching strategy, switching the network by the terminal from the current first wireless network to a second wireless network, wherein the type of the second wireless network is not limited, and the second wireless network can be a network with air interface service quality guarantee or a network without air interface service quality guarantee. And after the terminal is switched to the second wireless network, the terminal keeps the conversation service established through the first wireless network through the second wireless network.
Prior to switching to the second wireless network, the method further comprises: acquiring a coding format corresponding to the call service, and adjusting the coding rate of the coding format to obtain an adjusted call service; detecting the service quality parameter of the adjusted call service; and switching from the first wireless network to the second wireless network under the condition that the service quality parameter of the adjusted call service is determined to be matched with the service quality switching strategy.
When the service parameter of the call service is determined to be matched with the service quality switching strategy, determining that the service quality of the current call service is reduced, at the moment, acquiring a coding format corresponding to the call service, wherein the coding format corresponding to the call service is a coding type of voice coding or video coding during the call service, adjusting a coding rate to improve the service quality of the call service, taking the current call service as the voice call as an example, when the service quality of the current voice call is matched with the service quality switching strategy, acquiring a voice coding format used by the voice call, adjusting the coding rate of the voice coding according to the service quality parameter, and acquiring the service parameter of the call service after the coding rate is adjusted. The speech coding type may include, for example, an AMR-WB adaptive wideband speech coding, and when the coding rate is adjusted, the terminal may automatically adjust the coding rate according to the 3GPP protocol, for example: automatically adjusting the coding rate according to the bandwidth of the AS application service; and automatically reducing the voice coding rate according to the error rate/packet loss rate of the data packet so as to improve the error rate/packet loss rate of the voice frame. And after the coding rate of the call service is adjusted, matching the service parameter at the moment with a service quality switching strategy, and switching from the first wireless network to the second wireless network under the condition of determining that the adjusted service quality parameter of the call service is matched with the service quality switching strategy. Here, when it is determined that the qos parameter of the current call service and the qos switching policy are satisfied, the network in which the terminal performs communication is not directly switched, but the coding rate at which the terminal performs communication service is adjusted in the current first wireless network, adjustment is performed from the terminal itself, and network switching is performed when it is determined that the adjusted qos parameter cannot satisfy the qos.
In practical use, when the first wireless network is WLAN and the second wireless network is EUTRAN, according to the specifications of 3GPP36.304 and 3GPP 24.304, the handover requirement of WLAN- > EUTRAN is satisfied
The source WLAN cell satisfies:
ChannelUtilizationWLAN>ThreshChUtilWLAN,High；or
BackhaulRateDlWLAN<ThreshBackhRateDLWLAN,Low；or
BackhaulRateUlWLAN<ThreshBackhRateULWLAN,Low；or
BeaconRSSI<ThreshBeaconRSSIWLAN,Low；
that is, the channel utilization rate of the WLAN is less than the threshold, the backhaul downlink bandwidth of the WLAN is less than the threshold, the backhaul uplink bandwidth of the WLAN is less than the threshold, or the RSSI of the WLAN is less than the threshold, and when any one of the above conditions is satisfied, the handover is performed.
In the embodiment of the invention, when the terminal meets the conditions and the service parameters meet the service quality switching strategy, the network switching is still executed, so that the terminal determines whether to switch according to the service quality of the call of the terminal on the basis of meeting the resident conditions of the existing protocol, and service guarantee is provided for the call service of the terminal.
Example two
In the embodiment of the present invention, a method for switching a network provided by the embodiment of the present invention is described where the first wireless network is WIFI and the second wireless network is EUTRAN.
According to 3GPP36.304 and 3GPP 24.304, when WLAN- > EUTRAN handover,
the source WLAN cell satisfies:
ChannelUtilizationWLAN>ThreshChUtilWLAN,High；or
BackhaulRateDlWLAN<ThreshBackhRateDLWLAN,Low；or
BackhaulRateUlWLAN<ThreshBackhRateULWLAN,Low；or
BeaconRSSI<ThreshBeaconRSSIWLAN,Low；
that is, the channel utilization rate of the WLAN is less than the threshold, or the backhaul downlink bandwidth of the WLAN is less than the threshold, or the backhaul uplink bandwidth of the WLAN is less than the threshold, or the RSSI of the WLAN is less than the threshold.
The target EUTRAN cell satisfies:
RSRPmeas>ThreshServingOffloadWLAN,HighP；and
RSRQmeas>ThreshServingOffloadWLAN,HighQ；
the RSRP measurement value is above a threshold, the RSRQ cut value is above a threshold,
when the terminal measures that the RSSI of the WLAN network is good, the channel utilization rate also reaches the standard, the uplink and downlink bandwidths of the backhaul line are good, the switching condition is not met, and the condition of residing in the WLAN network is met when all parameters meet the residence threshold. Wherein, threshcautil WLAN, threshbackratedl WLAN, threshbackrateul WLAN, and threshbeacon RSSI WLAN are residence thresholds corresponding to channel utilization rate, backhaul downlink bandwidth of WLAN, backhaul uplink bandwidth of WLAN, and RSSI of WLAN, respectively.
When the terminal is talking on the WLAN, it listens to Qos related parameters of the wireless communication system, such as parameters of talk bandwidth, error rate, time delay, JITTER, etc. If adaptive coding, such as AMR-WB, is used during the terminal call, the terminal can adaptively decrease/increase the coding rate according to the change of the QoS parameter. When the adaptive coding rate is reduced to the lowest, although the WLAN still meets the residence threshold, the WLAN cannot meet the call QoS guarantee, the terminal starts a switching algorithm based on the QoS guarantee and switches from the WLAN without air interface QoS guarantee for VOWIFI service to EUTRAN with QoS guarantee for EUTRAN VOLTE.
When the speech time delay and the packet loss rate of the user in actual communication through the terminal are large, and the communication quality is poor, the terminal needs to continue to communicate through VOWIFI according to the protocol specification, and a better EUTRAN network around the terminal cannot be switched and used. By the method of the embodiment of the invention, when the speech time delay, the packet loss ratio and the like occur in the actual call process of the user through the terminal, so that the call quality is not good, the current network for carrying out the call is switched to another network for carrying out the call continuously.
EXAMPLE III
In the embodiment of the present invention, the method for switching a network provided in the embodiment of the present invention is further described in a specific application scenario, as shown in fig. 2, specifically including:
s201, registering a terminal to a first wireless network;
the mobile terminal is powered on and registers to a first wireless network, and the first wireless network is a wireless quality of service (Qos) guaranteed network, such as a Wireless Local Area Network (WLAN).
S202, the terminal establishes VOWIFI voice call;
at this time, the terminal establishes a VOWIFI voice call with another terminal through the triggering of the user, and determines the voice coding type, such as AMR-WB adaptive wideband voice coding, through network negotiation.
S203, acquiring a service quality parameter, and matching the service quality parameter with a service quality switching strategy;
and acquiring service quality parameters including call bandwidth, bit error rate, time delay and JITTER in the voice call process of the terminal. When the network environment changes, the quality of service parameters change, for example, b ═ AS access bandwidth becomes smaller, or the speech error rate increases, jitter increases, and the like. At this time, it is determined whether the qos parameter after the network environment change matches the qos switching policy. And when the reduced bandwidth is smaller than the call bandwidth threshold, the increased error rate is larger than a preset error rate threshold or the increased JITTER is larger than a preset JITTER threshold, determining that the service quality parameter after the network environment is changed is matched with the service quality switching strategy.
S204, adjusting the coding rate;
here, the coding rate may be adjusted according to the quality of service parameter; for example, the coding rate is automatically adjusted according to the bandwidth of the AS application service; and automatically reducing the voice coding rate according to the error rate/packet loss rate of the data packet so as to improve the error rate/packet loss rate of the voice frame. When the coding rate is automatically adjusted according to the bandwidth of the AS application service, the adjustment may be performed according to the table shown in fig. 3; when the speech coding rate is automatically decreased according to the packet error rate/packet loss rate, the adjustment may be performed according to the table shown in fig. 4. For example: in the process of a call, if the terminal adopts AMR adaptive speech coding, if the packet error Loss Rate exceeds 1%, the speech coding Rate is firstly considered to be reduced, and if the speech coding Rate is reduced to the lowest Rate, but the packet Loss Rate is still higher than 1%, the switching is carried out.
S205, obtaining the service quality parameter after adjusting the coding rate, and matching with the service quality switching strategy;
when the terminal adjusts the voice coding rate, the service quality parameter after the coding rate is adjusted is obtained, the service quality parameter after the coding rate is adjusted is matched with a service quality switching strategy, and when the adjusted service quality parameter is determined to still not meet the Qos packet loss/error rate of the voice call and the data transmission delay, the terminal starts the network switching even under the condition that the channel utilization rate of the WLAN, the RSSI and the uplink and downlink bandwidths of the backhaul network all meet the WLAN residence conditions.
S206, network searching;
after the terminal starts network switching, network searching based on QoS guarantee is started, and a second wireless network is searched, for example: EUTRN LTE.
S207, determining whether the second wireless network meets the residence condition;
after the terminal initiates network search, if the searched second wireless network meets the residence threshold of the LTE network and both RSRP and RSRQ meet the conditions, S208 is executed to switch to the second wireless network, switching is carried out from VOWIFI to VOLTE, and the call is continuously kept in the second wireless network. If the searched second wireless network still does not meet the switching threshold value specified by the protocol, S209 is executed to keep the call on the first wireless network and continue searching for the network.
