Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application 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 present application and are not intended to limit the present application.
In the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.
With the development of mobile communication technology and the increase of communication frequency bands, one terminal device may often support networks with multiple communication frequency bands or multiple communication systems for network communication. At present, in order to improve the communication efficiency and reliability of a terminal device, the communication signal quality of a network of the terminal device is monitored, and the network switching of the terminal device is realized according to the communication signal quality.
Conventionally, the terminal device periodically scans each communication network, and measures communication parameters of each communication network, such as: communication parameters such as Reference Signal Receiving Power (RSRP) and Signal-to-Noise Ratio (SNR); then, the communication signal quality of the current network is determined through the judgment of the communication parameters, and further, under the condition that the communication signal quality of the current network is determined to be poor, the switching operation of the network is executed.
However, the conventional RSRP/SNR-based communication network switching only can ensure that a network with better signal quality in a potential selection is accessed, and cannot ensure that the accessed network schedules more resources, and even congestion may exist to cause communication congestion. Although the network device may take measures to allocate different communication resources to the user, the effect and timeliness cannot be guaranteed, and the communication quality is still poor.
The embodiment of the application provides a network switching method, which can switch a network according to communication signal resources of terminal equipment, and improve the communication quality and the communication rate of the terminal equipment; of course, the network may also be switched in combination with the quality of the communication signal and the communication signal resource, that is, in the case of good quality of the communication signal, the network may also be switched according to the communication signal resource, so as to ensure that the terminal device can perform communication in the network with good quality of the communication signal and many communication signal resources, thereby improving the communication quality and the communication rate.
The network switching method provided by the embodiment of the application can be applied to the application environment shown in fig. 1. Wherein, the terminal device 101 communicates with the network device 102 through a network; optionally, the terminal device 101 may establish network communication with the network device 102 through different networks to obtain network resources allocated to the terminal device 102 by the network device 102, so as to implement network data transmission. Wherein, different networks mean that at least one of communication frequency bands, cells or communication systems corresponding to the networks is different.
The network devices involved in the embodiments of the present application may include, but are not limited to: a base station and a Transmission Reception Point (TRP). Wherein, the base station: also called Radio Access Network (RAN) equipment, is a device for accessing a terminal to a wireless network, and may be a Base Transceiver Station (BTS) in global system for mobile communications (GSM) or Code Division Multiple Access (CDMA), a base station (nodeB, NB) in Wideband Code Division Multiple Access (WCDMA), an evolved node B (eNB or eNodeB) in Long Term Evolution (LTE), a relay station or access point, or a base station (gdnodeb, gNB) in a 5G network, and the like, without limitation.
The terminal device referred to in the embodiments of the present application may be a wireless terminal or a wired terminal, and the wireless terminal may be a device providing voice and/or other service data connectivity to a user, a handheld device having a wireless connection function, or other processing device connected to a wireless modem. Illustratively, the wireless terminal may be a mobile terminal, such as a mobile phone or a computer having a mobile terminal, e.g., a mobile device that may be portable, pocket, hand-held, computer-included, or vehicle-mounted, etc.
In an embodiment, as shown in fig. 2, a network handover method is provided, which is described by taking the application of the method to the terminal device in fig. 1 as an example, and includes the following steps:
step S201, obtaining a congestion state parameter of a first network to which the terminal device is currently connected.
The congestion state parameter of the first network is used for representing the congestion state of the first network. Optionally, the congestion status parameters of the network may include parameters related to communication resources of the network, such as: the resource scheduling information of the network includes, but is not limited to, the number of scheduled resource blocks, the number of scheduling times, the number of scheduled transmission streams, and the throughput rate.
When the terminal device performs network communication, it needs to acquire resource scheduling information from the network device, that is, the network device allocates a certain network resource to the terminal device, so that the terminal device can perform network communication based on the network resource. The terminal device can realize real-time and efficient network communication under the condition that the acquired network resources are abundant, but under the condition that the network resources acquired by the terminal device are deficient, the network communication efficiency is slow, the real-time performance is affected, and even communication blockage caused by network congestion may occur.
Therefore, in the embodiment, the terminal device is required to judge the congestion state of the first network currently accessed by the terminal device in real time in the network communication process, and switch the network accessed by the terminal device according to the congestion state, so as to ensure smooth network communication and improve timeliness of network communication.
In one implementation, the terminal device may obtain resource scheduling information of a currently accessed first network, and determine a congestion state parameter of the first network according to the resource scheduling information of the first network; optionally, the terminal device may use one or more of the resource scheduling information of the first network as the congestion state parameter of the first network, or may calculate the congestion state parameter of the first network according to at least two of the resource scheduling information of the first network.
For example, in the case that the resource scheduling information of the first network includes a throughput rate, the throughput rate of the first network may be used as a congestion state parameter of the first network to which the terminal device is currently accessing.
Exemplarily, under the condition that the resource scheduling information of the first network includes at least two of the number of scheduled resource blocks, the number of scheduling times and the number of scheduled transmission streams, the congestion state parameter of the first network to which the terminal device is currently accessed may be calculated according to each parameter and the corresponding preset coefficient in the resource scheduling information; for example: the weighted summation calculation can be performed according to each parameter in the resource scheduling information and the preset coefficient corresponding to each parameter, and the result of the weighted summation is used as the congestion state parameter of the first network to which the terminal device is currently accessed.
Step S202, if the congestion state of the first network meets a preset network congestion condition, sending a target measurement report to the network device.
The target measurement report is used for indicating the network equipment to carry out network switching on the terminal equipment. The preset network congestion condition may be a condition related to a network congestion degree, and the network congestion degree may be determined based on network resources allocated to the terminal device. It can be clear that the less network resources the terminal device is allocated, the higher the degree of network congestion.
For example, the preset network congestion condition may be that the congestion state parameter of the network reaches a preset network congestion threshold. Under the condition that the congestion state parameter of the first network reaches the preset network congestion threshold, it can be determined that the higher the network congestion degree of the first network to which the terminal device is currently accessed is, and the less network resources are allocated to the terminal device, and then it can be determined that the congestion state of the first network meets the preset network congestion condition. At this time, the terminal device may transmit a target measurement report for instructing the network device to perform network handover on the terminal device to the network device.
In an implementation manner, the terminal device may indicate that the network resource allocated to the terminal device is less and the network is in a congestion state at this time when it is determined that the congestion state parameter of the currently accessed first network is smaller than the preset network congestion threshold; in order to ensure the network communication quality of the terminal device, the terminal device may send a target measurement report to the network device for instructing the network device to perform network handover on the terminal device.
For the target measurement report, optionally, the target measurement report may include an instruction identifier for instructing the network device to perform network handover on the terminal device, where the instruction identifier may be a status bit identifier, such as: 1 indicates that network switching is performed, and 0 indicates that network switching is not performed; the instruction identifier may also be a network quality indicator of the terminal device, such as: and the network quality parameter carries out network switching under the condition that the network quality parameter is smaller than the network quality parameter threshold value, and does not carry out network switching under the condition that the network quality parameter is larger than or equal to the network quality parameter threshold value. Of course, the instruction identifier may also be an identifier in other forms, which is not specifically limited in this embodiment, as long as the instruction identifier can instruct the network device to perform network handover on the terminal device.
Step S203, receiving a network switching command sent by the network device, and executing a network switching operation according to the network switching command.
In this embodiment, after the terminal device sends the target measurement report to the network device, the network device may switch the first network to which the terminal device is currently accessed based on the target measurement report, so that the terminal device is switched from the first network to the second network. Optionally, the network device may determine a second network from other networks except the first network, and perform a network handover operation of switching the first network accessed by the terminal device to the second network, and in addition, the network device further needs to send a corresponding network handover command to the terminal device, and optionally, the network handover command may carry related information of the second network to be accessed. Therefore, after receiving the network switching command sent by the network device, the terminal device can execute the corresponding network switching operation according to the network switching command so as to cooperate with the network device to complete the network switching action.
Optionally, when determining the second network, the network device may select the second network with good communication quality according to the network quality and congestion level of each network other than the first network, or may select the second network with good communication quality with respect to the terminal device in combination with the geographical location of the terminal device. At least one of a communication frequency band, a cell or a communication system corresponding to the second network is different from that of the first network; for example: when the network resource of the cell corresponding to the first network to which the terminal device is currently accessed is deficient and the network is congested, the cell can be switched to a second network for communication, and the communication frequency band corresponding to the second network and the first network can be the same or different.
According to the network switching method, the terminal equipment acquires the congestion state parameter which corresponds to the currently accessed first network and is used for representing the congestion state of the first network, sends a target measurement report which is used for indicating the network equipment to carry out network switching on the terminal equipment to the network equipment under the condition that the congestion state of the first network is determined to meet the preset network congestion condition, and then executes network switching operation according to the network switching command under the condition that the terminal equipment receives the network switching command sent by the network equipment; that is to say, the network handover method in the embodiment of the present application can perform handover of a communication network in real time under the condition that a network to which a terminal device is currently accessed is congested and communication resources are deficient; compared with the traditional network switching method, the network switching method has the advantages that the network switching can be carried out according to the communication signal quality, and the network switching can be carried out according to the actually acquired network communication resources under the condition of better communication signal quality, so that the judgment dimensionality of the network switching is increased, the network switching effect can be improved, and the network communication quality of the terminal equipment can be further improved. In addition, by adopting the network switching method in the embodiment of the application, the network switching can be realized under the condition that the terminal equipment does not cut off the flow, the network switching efficiency can be improved, and the reliability and the stability of the network can be improved.
In an optional embodiment of the present application, as shown in fig. 3, before the terminal device sends the target measurement report to the network device in step S202, the method may further include a process of generating the target measurement report, where the process of generating the target measurement report may include the following steps:
step S301, setting a network quality parameter value of the first network to a first value, where the first value is less than or equal to a network quality parameter threshold value that can trigger network handover.
The network quality parameters of the network may include parameters for characterizing the network quality, such as Reference Signal Receiving Power (RSRP), signal-to-Noise Ratio (SNR), signal-to-Interference plus Noise Ratio (SINR), and the like.
When the terminal equipment carries out network communication based on a first network, the network quality corresponding to the first network can be detected in real time; optionally, the terminal device may obtain, in real time, various network quality parameter values corresponding to the currently accessed first network, including RSRP, SNR, SINR, and the like; then, the terminal device may send each network quality parameter value corresponding to the first network to the network device, such as: generating a measurement report according to each network quality parameter value corresponding to the first network, and sending the measurement report to network equipment; the network equipment can judge the network communication quality of the first network according to each network quality parameter value of the first network which is sent by the terminal equipment and is currently accessed by the terminal equipment; so that the network device performs network switching on the terminal device under the condition that the network communication quality of the first network is determined to be poor.
That is to say, for the network device, it may determine whether the first network currently accessed by the terminal device has a network communication quality problem according to a preset network quality parameter threshold that may trigger network handover, that is, when the network quality parameter of the first network currently accessed by the terminal device is greater than the network quality parameter threshold, it indicates that the network quality of the first network currently accessed by the terminal device is better, and network handover is not required; and under the condition that the network quality parameter of the first network currently accessed by the terminal equipment is less than or equal to the network quality parameter threshold, indicating that the network quality of the first network currently accessed by the terminal equipment is poor and network switching is required.
It should be noted that, for different terminal devices and different access networks, the same or different network quality parameter thresholds that can trigger network handover may correspond, and the network quality parameter thresholds may be set or modified by the user.
In this embodiment, the terminal device may instruct the network device to perform network switching on the terminal device when determining that the congestion state of the currently accessed first network meets a preset network congestion condition; at this time, the terminal device may set the network quality parameter value of the first network to a first value that is less than or equal to a network quality parameter threshold that may trigger a network handover, so that the network device may perform the network handover on the terminal device in a case where it is determined that the network quality parameter value of the first network is less than or equal to the network quality parameter threshold.
Step S302, a target measurement report is generated according to the first value.
After setting the network quality parameter value of the first network as a parameter value that can trigger network handover, the terminal device may generate a target measurement report according to a first value corresponding to the network quality parameter of the first network, and send the target measurement report to the network device.
In this embodiment, the terminal device sets a network quality parameter value of the first network to a first value that is less than or equal to a network quality parameter threshold value that can trigger network handover, and generates a target measurement report according to the first value, so that the network device determines to perform network handover on the terminal device according to the target measurement report; by adopting the mode, the network switching of the terminal equipment can be realized without cutting off the flow, and the reliability and the stability of the network switching are improved.
In an alternative embodiment of the present application, as shown in fig. 4, the implementation process of the terminal device generating the target measurement report according to the first value in step S302 may include the following steps:
step S401, a network list is obtained, where the network list includes at least one identifier of a second network.
The second network is a network supported by the terminal device except the first network currently accessed by the terminal device.
Optionally, the network list may include all networks supported by the terminal device except the first network, and may also include at least one of the networks with better network quality and more network resources. Each second network in the network list may be sorted according to network quality and network resource, may also be sorted according to a user-defined order, may also be sorted according to an identifier of a network, and the like, and of course, each second network in the network list may also be sorted randomly; this embodiment is not particularly limited thereto.
Optionally, the terminal device may obtain a network quality parameter and a congestion state parameter of the network for each network supported by the terminal device, and perform priority ranking on each network according to the network quality parameter and the congestion state parameter of each network; then, at least one network with high priority is selected as a switchable second network according to the priority ranking, and a network list is generated according to the identification of the at least one second network.
Step S402, a target measurement report is generated according to the first value and a network list, wherein the network list is used for instructing the network equipment to switch the terminal equipment from the first network to the second network.
Wherein, the target measurement report includes a network quality parameter value (i.e. the modified first value) of the first network currently accessed by the terminal device and an identifier of the at least one switchable second network.
That is, in this embodiment, when the terminal device sends the network switching instruction to the network device, the terminal device also carries at least one second network that the terminal device desires to switch, so that the network device performs network switching selection, so that when the network device performs network switching operation on the terminal device, the network device can perform network switching with high efficiency and high reliability according to actual requirements of the terminal device, and the network switching effect is improved.
In an optional embodiment of the present application, as shown in fig. 5, an implementation process of the terminal device acquiring the network list in step S401 may include the following steps:
step S501, periodically accessing different second networks, and after accessing the second networks each time, acquiring congestion state parameters of the accessed second networks, wherein the congestion state parameters of the second networks are used for representing the congestion states of the second networks.
Optionally, the terminal device may also periodically access a second network supported by the terminal device, except the first network, in the process of performing network communication based on the currently accessed first network, and determine the network congestion state of each second network; the terminal device may sequentially access different second networks according to a preset network sequence, and obtain the congestion state parameter of the accessed second network after accessing the second network each time.
Optionally, referring to the description about the related content of obtaining the congestion status parameter of the first network in step S201, similarly, the resource scheduling information corresponding to the accessed second network may be obtained, and the congestion status parameter of the second network is determined according to the resource scheduling information corresponding to the second network; for details of implementation, reference may be made to step S201 described above, which is not described herein again.
In one implementation manner, the terminal device may implement a network handover procedure in a multi-process manner, exemplarily, the terminal device may include a first process and a second process, and the terminal device may perform network communication and handover in the first process, that is, access to a first network through the first process, and implement data interaction with the network device based on the first network, and perform a network handover operation. And the second process monitors the congestion state of other networks, namely the second network, that is, the terminal device can periodically access different second networks through the second process, and after accessing the second network each time, the congestion state parameter of the accessed second network is acquired through the second process.
Step S502, a network list is generated according to the congestion state parameters of the different second networks.
Optionally, the terminal device may perform network congestion sorting on different second networks according to congestion state parameters of the different second networks, perform priority sorting on each second network according to a sequence from weak to strong of the network congestion, and then generate the network list according to each second network after the priority sorting.
In one implementation manner, the terminal device may perform priority ordering on each second network through the second process to generate a network list; of course, the terminal device may also obtain the congestion state parameters of the second networks acquired by the second process through the first process, and perform priority ranking on the second networks according to the congestion state parameters of the second networks, so as to generate the network list.
In this embodiment, the terminal device periodically accesses to different second networks, and after each access to the second network, acquires congestion state parameters of the accessed second network, which are used for characterizing the congestion state of the second network, and then generates a network list according to the congestion state parameters of the different second networks; by adopting the method of the embodiment, the switchable network list can be determined according to the actual congestion states of other second networks supported by the terminal device except the currently accessed first network, and the switchable second networks can be subjected to priority sequencing according to the actual congestion states of the second networks, so that when the network device performs network switching on the terminal device, the network device can be switched to a network with better network performance for the communication of the terminal device, and the effect of network switching can be improved; in addition, the problem that the network switching needs to be continued due to the fact that the network after switching still has the problem of network congestion can be avoided, and the reliability of network switching and the efficiency of network switching are improved.
For the step of generating the network list by the terminal device according to the different congestion state parameters of the second network in step S502, two different implementation manners will be listed below to discuss this step in detail.
The first method comprises the following steps: generating a network list according to at least one network with a better network congestion state, as shown in fig. 6, specifically includes:
step S601, according to the congestion state parameters of different second networks, obtaining a target network whose congestion state does not meet the network congestion condition from the different second networks.
Step S602, a network list is generated according to the target network.
As can be seen from the above description in step S202, when the congestion state of the network meets the network congestion condition, it indicates that the terminal device is allocated less network resources and the network is in a congestion state, and in this case, the network of the terminal device needs to be switched. Then, for a network whose congestion state does not meet the network congestion condition, it indicates that the congestion degree of the network is low, and the terminal device is easily allocated to more network resources under the network.
Therefore, in this implementation manner, the terminal device may screen out, from all the second networks, a target network whose congestion state does not meet the network congestion condition, that is, a target network with more network resources, according to the congestion state parameter of each second network; further, a network list is generated based on the target networks, and optionally, the target networks in the network list may be arranged randomly, or may be arranged according to the identification order of the target networks, or may be arranged according to the congestion degree of each target network in a priority manner.
Second, generating a network list according to at least one network with a better network congestion state and at least one network with a worse network congestion state, as shown in fig. 7, specifically includes:
step S701, according to the congestion state parameters of different second networks, obtaining a target network whose congestion state does not meet the network congestion condition and a non-target network whose congestion state meets the network congestion condition from the different second networks.
Step S702, setting the network quality parameter value of the non-target network to a second value, where the second value is less than or equal to the network quality parameter threshold value that does not meet the network availability.
Step S703, a network list is generated according to the target network, the network quality parameter value of the target network, the non-target network, and the second value.
The network list includes not only target networks capable of supporting handover but also non-target networks not supporting handover, so that the network device selects one network from the target networks capable of supporting handover, performs network handover on the terminal device, and prohibits the network device from switching the first network of the terminal device to the non-target networks.
According to the description in step S301, it can be known that, when it is determined that the first network has the network congestion problem, the network quality parameter value of the first network may be modified into a network quality parameter value that can trigger network handover, and is used to instruct the network device to handover the first network to which the terminal device is currently connected.
Then, for a non-target network in the second network with a network congestion problem, the network quality parameter value of the non-target network may be modified to a network quality parameter value that does not conform to the network availability, so as to instruct the network device to prohibit the terminal device from accessing the non-target network, so as to avoid performing the network handover operation again, and improve the network handover efficiency and the network handover effect.
It should be noted that, for the above-mentioned embodiments shown in fig. 5 to fig. 7, on the basis of determining the network list according to the congestion state parameters of the respective second networks, that is, the congestion states of the respective second networks, the terminal device may also determine the network list comprehensively in combination with the network quality parameters of the second networks; that is to say, the target network in the network list that can support handover may be a second network whose network quality parameter meets a preset network quality condition and whose congestion state parameter does not meet a network congestion condition, that is, the target network is a second network with better network quality and weaker network congestion; the non-target network not supporting handover in the network list is a second network whose network quality parameter does not satisfy a preset network quality condition and/or whose congestion state parameter satisfies a network congestion condition, that is, the non-target network is a second network with poor network quality and/or strong network congestion.
In an optional embodiment of the present application, a premise that the terminal device in step 201 performs the steps of the network switching method in each of the above embodiments may be that the terminal device supports a network switching function, that is, the terminal device may perform the steps of the network switching method in each of the above embodiments when supporting the network switching function, and the terminal device does not perform the steps of the network switching method when the terminal device does not support or prohibit the network switching function; by the method limitation in this embodiment, flexible network handover control can be provided for a user, for example: in order to avoid an increase in power consumption and reduce power usage of the terminal device, the user may choose to turn off the network switching function.
Based on this, for the terminal device, a target communication mode related to network switching, which is a mode in which network switching is performed according to the communication congestion status of the terminal device, may be set. Then, for step S201, acquiring the congestion state parameter of the first network to which the terminal device currently accesses may include: under the condition that the target communication mode of the terminal equipment is enabled, executing the step of acquiring the congestion state parameter of a first network currently accessed by the terminal equipment; that is, in the case that the user selects to enable the target communication mode, the terminal device implements automatic switching of the network according to the communication congestion status of the currently accessed network.
For example, the target communication mode may also be referred to as a train mode, and the naming of the target communication mode in this embodiment is not particularly limited as long as the target communication mode can perform network switching according to the communication congestion status of the terminal device.
