Description
Technical Field
the present invention relates to the field of network handover technologies, and in particular, to a method and an apparatus for network handover, and a user equipment.
background
after VoLTE, i.e. voice services based on IP Multimedia Subsystem (IMS), has been substantially improved, developed countries in north america have begun to gradually popularize WIreless FIdelity (WiFi) calls (Calling), which is also the reason for the increasing strength of internet enterprises. For Voice over internet Protocol (VoIP), the relevant service operator has to change attitudes. Early WiFi Calling was not able to switch to Cellular (Cellular) network, i.e. if the user moved to an area outside of the service WiFi hotspot, a dropped call would occur.
WiFi Calling, the third Generation Partnership Project (3 GPP), adopted three network modes that can switch between WiFi and Cellular, where S2b has gradually dominated the wind into the mainstream. In summary, the feature of S2b is that any WiFi can access the evolved packet data gateway (ePDG) of the core network on the WiFi side of the operator, and then access the IMS through the ePDG to connect to the traditional Circuit Switched (CS) core network. The security of this link can be guaranteed by IP security protocol (IPSec), but Quality of Service (QoS) cannot be guaranteed. Since the access network in the front segment may include both the access services provided by other operators and the local area network built by the user. The disadvantage of the S2b approach is evident in that it is difficult to provide adequate QOS guarantees for services such as voice type that require explicit QOS requirements.
For QOS, the terminal (i.e. user equipment) has the capability of measuring its service WiFi hotspot, and signal strength, signal quality and delay can be obtained through measurement, but from the perspective of the station-to-network, the measurement has low referential property to QOS. Unlike increasingly flattened Cellular, under such network conditions, a terminal reaches its core network through multiple levels of routes, and QOS of the routes at present lacks an effective control mechanism and strategy. Therefore, measuring only the current serving WiFi hotspot does not reflect the overall QOS condition. There is currently no effective solution for this service state.
since the current WiFi to Cellular handover control mechanism is not well defined in the standard, WiFi technology is not itself the control area of 3GPP or 3GPP 2. The current general strategy for handover is to measure the signal strength and signal quality of the current service-providing WiFi hotspot by the terminal (typically only the signal strength is tested). If the signal strength (or quality) is below a certain threshold and the Cellular signal strength (or quality) is above a certain threshold, the handover is made to Cellular. The switching ignores the QOS condition in the whole service flow to a great extent, which causes the problem that the conversation quality is not good in the conversation process of the user.
in addition, from the perspective of voice, almost all voice quality tests in the industry are loop tests, that is, voice must be returned from the sender to the receiver to the sender, which cannot be implemented in the current network, and if implemented, normal use of the user is affected.

Detailed Description
exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
First embodiment
as shown in fig. 1, a first embodiment of the present invention provides a network switching method, which is applied to a first user equipment (e.g., a smart phone, a tablet computer, etc.) under a first network, where an area where the first user equipment is located is also covered by a second network, and the method includes:
Step S101, during the process of communicating with the second user equipment, the communication service quality of the first user equipment is measured to obtain a first measurement result.
In the first implementation of the present invention, the first network may be a WIFI network, an area where the second user equipment is located is covered by a third network, and the third network may be the same network as the second network, for example, both Long Term Evolution (LTE) networks, although the second network and the third network may also be different networks, for example, the second network is an LTE network, and the third network is a Global System for mobile communications (GSM) network. It is to be understood that, in the first embodiment of the present invention, the specific forms of the first network, the second network, and the third network are not limited. It should be noted that the second network is a network on which the first user equipment is standby.
Step S102, receiving a second measurement result sent by the second user equipment.
wherein the second measurement result is used for indicating the call service quality of the second user equipment.
in the first embodiment of the present invention, after the second user equipment that has performed a call with the first user equipment has measured its own call service quality, the second user equipment sends the second measurement result obtained by the measurement to the first user equipment, so that the first user equipment performs subsequent operations. There are various ways for the second user equipment to send the second measurement result, such as short message, Packet (PS) data, Unstructured Supplementary Service Data (USSD), and so on. It should be noted that, when the second ue sends the second measurement result, an acknowledgement and a retransmission mechanism are set for the second measurement result. That is, after receiving the second measurement result, the first user equipment needs to reply an Acknowledgement message, such as an Acknowledgement Character (ACK), to the second user equipment within a certain specified time (for example, 60 seconds), otherwise, the second user equipment will send the second measurement result to the second user equipment until the first user equipment replies the Acknowledgement message.
And step S103, controlling the first user equipment to switch from the first network to the second network or controlling the first user equipment not to switch the network according to the first measurement result and the second measurement result.
In the first embodiment of the present invention, the first user equipment controls the network switching of the first user equipment according to the actual QOS conditions (i.e. the first measurement result and the second measurement result) to obtain an optimal call network, thereby providing a better voice service for the user. It should be noted that the first user equipment should have a network handover capability.
in a first embodiment of the present invention, the first measurement result includes: a first error rate of the first user equipment in the first network, and a delay parameter between the first user equipment and a gateway (e.g., ePDG) for handing over the first user equipment from the first network to the second network, the second measurement comprising a second error rate of the second user equipment in the third network. The first error rate is obtained when the first user equipment measures the error code condition of the current first network, the delay parameter can be obtained by the first user equipment performing ping operation on a server (namely the gateway for switching the first user equipment from the first network to the second network) providing service for the first user equipment, and the second error rate is obtained when the second user equipment measures the error code condition of the current physical layer or Media Access Control (MAC) layer of the third network. The gateway for switching the first user equipment from the first network to the second network may be an ePDG or another gateway depending on the actual link.
in the first embodiment of the present invention, the first user equipment controls the network switching of the first user equipment according to the call service quality of the first user equipment and the second user equipment during the call with the second user equipment, so that the problem of poor call quality during the call of the user is solved, and an effect of providing better call quality for the first user equipment and the second user equipment during the voice call is achieved.
In the first embodiment of the present invention, there are two specific implementations of the step S101.
In the first method, when a user using the first user equipment or a user using the second user equipment feels that voice quality is poor during a call with the second user equipment, the user using the second user equipment may input a measurement instruction through a side key (or a virtual key) of the first user equipment, so that the second user equipment measures the call service quality of the second user equipment to obtain a second measurement result, and sends a first measurement instruction to the first user equipment, so that the first user equipment measures the call service quality of the first user equipment according to the first measurement instruction after receiving the first measurement instruction to obtain a first measurement result.
in a second manner, in the process of communicating with the second user equipment, when the user using the first user equipment or the user using the second user equipment feels that the voice quality is poor, the user using the first user equipment may input a second measurement instruction through a side key (or a virtual key) of the first user equipment, so that the first user equipment measures the call service quality of the first user equipment to obtain a first measurement result, and sends a third measurement instruction to the second user equipment, where the third measurement instruction is used to instruct the second user equipment to measure the call service quality.
It should be noted that, the first measurement instruction and the third measurement instruction are provided with corresponding acknowledgement and retransmission mechanisms, that is, after receiving the first measurement instruction, the first user equipment needs to reply to the second user equipment with an ACK message within a certain specified time (for example, 60 seconds), and after receiving the third measurement instruction, the second user equipment needs to reply to the first user equipment with an ACK message within a certain specified time (for example, 60 seconds).
in the first embodiment of the present invention, the step S103 specifically includes the following steps:
And the first step, judging whether the second error rate is less than or equal to a first preset value, if the second error rate is less than or equal to the first preset value, executing the second step, and if the second error rate is greater than the first preset value, executing the third step.
In the first embodiment of the present invention, if the second error rate is less than or equal to the first preset value, it indicates that the second error rate is very low, and the requirement of voice communication can be completely satisfied.
And the second step is to control the first user equipment to switch from the first network to the second network.
And thirdly, judging whether the second error rate is smaller than a second preset value, if the second error rate is larger than the first preset value and smaller than the second preset value, executing the fourth step, and if the second error rate is larger than or equal to the second preset value, executing the seventh step.
in the first embodiment of the present invention, if the second error rate is greater than the first preset value and less than the second preset value, it indicates that the second error rate is significant, and there is a possibility that the user will be affected, and the first user equipment needs to determine whether to switch the network according to the first measurement result; and if the second error rate is greater than or equal to the second preset value, the second error rate is very high and cannot meet the call requirement of the user, and the first user equipment does not need to switch the network.
And step four, judging whether the first user equipment needs to switch the network or not according to the first measurement result, if the first user equipment needs to switch the network, executing the step five, and if the first user equipment does not need to switch the network, executing the step six.
In the first embodiment of the present invention, the step of determining whether the first user equipment needs to switch the network specifically includes: firstly, judging whether the first error rate is greater than or equal to a third preset value, if so, determining that the first user equipment needs to switch the network, if not, continuously judging whether the delay parameter is greater than or equal to a fourth preset value, if so, determining that the first user equipment needs to switch the network, and if not, determining that the first user equipment does not need to switch the network. That is, as long as the first error rate is greater than or equal to the third preset value or the delay parameter is greater than or equal to the fourth preset value, it is determined that the first user equipment needs to switch the network, otherwise, the network does not need to be switched.
And fifthly, controlling the first user equipment to switch from the first network to the second network.
sixthly; and controlling the first user equipment not to perform network switching.
and seventhly, controlling the first user equipment not to perform network switching.
It should be noted that, in order to improve the accuracy of network handover, the first preset value and the second preset value are both set according to a specific form of a third network, similarly, the third preset value is set according to a specific form of the first network, and the fourth preset value is set according to a specific link between the first user equipment and a gateway for handing over the first user equipment from the first network to the second network.
in the first embodiment of the present invention, it is assumed that the first network is a WIFI network, the second network is a VoLTE network, and the third network is a GSM network, and a gateway for switching the first user equipment from the first network to the second network is an ePDG.
The network structure when the first user equipment and the second user equipment are in a conversation is shown in fig. 2, where for the first user equipment, the connection between the first user equipment and the ePDG is an untrusted connection, the connection between the ePDG and the IMS is a trusted connection, and for the second user equipment, the connection between the base transceiver station-base station controller (BTS-BSC) access network and the IMS is a trusted connection. In addition, the MSC in fig. 2 is a mobile switching center, and the GMSC is a mobile switching center gateway. It should be noted that the GMSC is an optional gateway, i.e., there may be GMSC or none.
In the process of communication, if a user of first user equipment or a user of second user equipment finds that voice quality cannot meet communication requirements, the user of the second user equipment can input a measurement instruction through a side key (or a virtual key) of the first user equipment, so that the second user equipment measures the communication service quality of the second user equipment to obtain a second measurement result, and sends a first measurement instruction to the first user equipment, so that after receiving the first measurement instruction, the first user equipment measures the network condition of a WiFi hotspot according to the first measurement instruction and performs ping operation on an ePDG server to obtain a first measurement result; certainly, when the user of the first user equipment or the user of the second user equipment finds that the voice quality cannot meet the call requirement, the user using the first user equipment can also input a second measurement instruction through a side key (or a virtual key) of the first user equipment, so that the first user equipment measures the call service quality of the first user equipment to obtain a first measurement result, and sends a third measurement instruction to the second user equipment, wherein the third measurement instruction is used for indicating the second user equipment to measure the call service quality. I.e. any of the two parties to the call can initiate the measurement. It should be noted that the first measurement instruction and the third measurement instruction may be transmitted by USSD, short message, PS data, and the like, and the first measurement instruction and the third measurement instruction are provided with corresponding response and retransmission mechanisms, that is, after receiving the measurement instruction, the other party needs to reply to the ACK message within a certain specified time (for example, 60 seconds). It should be noted that the second measurement result is obtained when the second user equipment measures an error code condition of a physical layer or a Media Access Control (MAC) layer of the current third network, and correspondingly, the first preset value is 1.6% and the second preset value is 6.4% of the call quality (Rxqual) of the access network in the current GSM network. Similarly, the first error rate is an error rate of a WiFi hotspot, the delay parameter is a delay parameter from the first user equipment to the ePDG, and accordingly, the third preset value is 5% and the fourth preset value is 500 milliseconds.
after the first user equipment obtains the first measurement result and receives the second measurement result, as shown in fig. 3, the step of controlling the first user equipment to switch from the first network to the second network, or controlling the first user equipment not to switch the network includes:
step S301, judging whether Rxqual is less than or equal to 3, if the Rxqual is less than or equal to 3, executing step S302, and if the Rxqual is greater than 3, executing step S303;
Wherein, Rxqual being less than or equal to 3 is equivalent to the second error rate being less than or equal to 1.6%.
step S302, controlling the first user equipment to be switched to VoLTE;
step S303, judging whether Rxqual is less than 6, if the Rxqual is less than 6, executing step S304, and if the Rxqual is greater than or equal to 6, executing step S306;
Wherein, an Rxqual of less than 6 is equivalent to a second error rate of less than 6.4%, and an Rxqual of greater than or equal to 6 is equivalent to a second error rate of greater than or equal to 6.4%.
step S304, judging whether the error rate of the WiFi hotspot is more than or equal to 5%, if so, executing step S302, and if not, executing step S305;
Step S305, judging whether the time delay parameter is greater than or equal to 500 milliseconds, if the time delay parameter is greater than or equal to 500 milliseconds, executing step S302, and if the time delay parameter is less than 500 milliseconds, executing step S306;
Step S306, controlling the first user equipment not to perform network switching.
Therefore, the network switching method can provide more flexible and stable service for both parties of a call by combining the actual network deployment condition without increasing any hardware cost (namely, the cost is low), thereby improving the user experience.
