Detailed Description
In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.
In the technical evolution process of the mobile network system, when the previous generation network system, i.e. the first network system, is upgraded to the updated network system, i.e. the second network system, the system deployment is often required to be additionally arranged, which is different from the support of the packet data service to the voice service under the second network system. For example, when upgrading from 2/3G to 4G LTE, the system needs to deploy an IMS system in a 4G core network to provide a VoLTE voice service to the terminal; or when upgrading from 4G + EPC to 5G +5GC, the network system needs to deploy an IMS system in the 5G core network to provide the VoNR voice service for the terminal. Due to the factors related to the upgrading of the terminal capability, the changing of the transmission network configuration and the consideration of the operation investment cost of the operator during the system upgrading, the operator tends to meet the requirement of the packet data service under the more advanced system in the period before the second network system is completely upgraded and deployed, and the voice service is carried out under the old system in a fallback mode. For example, when upgrading from 2/3G to 4G LTE, in a system not having a VoLTE function, a terminal performs a voice service and needs to fall back to 2/3G first, and for example, when upgrading from 4G + EPC to 5G +5GC, a 5G terminal performs a voice service in an SA network and needs to fall back to 4G first (if 4G does not support further fall back to 2/3G), after the voice service is finished, in order to better utilize the advantages of an update system in terms of rate throughput and resource utilization rate of a packet service, it is desirable that the terminal can return to a network system in an update system quickly.
In another case, when the first network system and the second network system coexist, especially at an early stage of system upgrade, the second network system of the update system has a large blind area in signal coverage, and the coverage area is not better than that of the first network system, when the terminal performs a Voice service in the second network system with a Voice service, the terminal moves from a coverage area to a non-coverage area, and when the first network system has coverage, the first network system switches the terminal in a connection state from the second network system to the first network system, which is Voice service Continuity (SRVCC). In the first network system, after the terminal has performed the voice service, the first network system may choose to return the terminal to the second network system as soon as possible. In both cases, the terminal needs to fall back from the first network system to the second network system, and it is desirable that the terminal can return to the second network system quickly after the voice service is finished.
The disadvantages of the fast feedback judgment method of the access unit base station in the existing network system are briefly described as follows: (1) the current terminal returns to the first network system from the second network system to carry out voice service, because different terminals realize the difference of protocol version degrees, the terminal can not carry correct reason values completely, the first network system access unit can only know the reason for initiating the access of the terminal by identifying the reason values accessed or switched in, and judge whether to implement a strategy for returning to the second network system quickly after the voice is finished according to the reasons, on the premise that the access reason can not be identified, the access unit continues to keep the terminal in a connection state and provides service according to a common access type, and the terminal can not return to the second network system in time; (2) the current terminal returns to the first network system from the second network system to perform voice service, even if the access unit of the first network system can identify the access reason and initiate quick return, when a target cell is selected during quick return, the current quick return method only performs blind return based on the configuration of the access unit of the first network system, or performs return after voice service is completed and measurement is performed by forced configuration and measurement is performed after measurement report is performed, current service requirements are not considered, under the condition of small traffic volume, the problem that frequent interoperation between the first network system and the second network system is likely to occur, meanwhile, the first network system performs access according to a candidate target access unit which is measured by the forced configuration, and when the selected access network system has parameter configuration and other network problems, the quick return failure is caused.
The above disadvantages may cause the current terminal to return to the first network system from the second network system for performing the voice service, after the voice service is completed, the access unit continues to maintain the terminal in the connected state and provide the service according to the normal access type, the terminal cannot return to the second network system in time, or the access unit in the second network system with an error is selected for access, which is not favorable for providing the whole system with low throughput, has an influence on the service experience of the user, and in an individual wireless environment, the wireless link of the terminal in the selected second network system may fail, causing network interruption. In view of the above disadvantages, the embodiments of the present disclosure provide a network communication method, which is specifically described below by way of embodiments.
Fig. 1 is a flowchart of a network communication method provided by an embodiment of the present disclosure, which may be executed by a network communication device, where the device may be implemented by software and/or hardware, and may be generally integrated in an electronic device. As shown in fig. 1, the method is applied to an access unit of a first network system, and includes:
The first network system is a network system supporting voice service, the second network system is a network system which is accessed by a terminal in history and does not have the capability of providing voice service, and the communication protocol versions of the first network system and the second network system are different.
In a mobile communication service, when a first network system and a second network system coexist, the capability of different network systems needs to be considered for providing a packet data service and a voice service for a terminal, and for the voice service, because the second network system does not have the service capability of providing the voice service or the update coverage of the second network system is insufficient, when the terminal performs the voice service, the terminal originally residing in the second network system needs to be dropped back into the first network system, and the first network system provides the voice service.
The access service information refers to multi-angle comprehensive information such as access related information of a terminal accessing a first network system, recording information of a key capability interaction process, recording information of a terminal on a service situation in the first network system, and the like. The access information may include information related to the terminal accessing the first network system, and may include information such as access time, access reason, and access type. The voice service information may be related information when the terminal performs a voice service, and specifically may include whether to initiate establishment of a voice service bearer or a session flow or whether to have a cut-in carrying the voice bearer and the voice session flow, time for initiating a voice, whether a voice service signaling plane is normally established, whether a connection based on a data plane is normal, a voice duration, a voice service connection end time, and the like. The interoperation information refers to interoperation capability information interacted between the terminal and the core network, and may specifically include whether the terminal supports residence of different frequency bands in the second network system, whether the terminal supports switching to the second network system in a connected state, whether a switching interface between the first network system and the second network system exists, and the like. The data service information refers to information related to services other than voice services, and may specifically include whether a packet data plane service exists simultaneously, a data plane throughput rate, a service flow in a continuous time, and the like.
In the embodiment of the disclosure, after accessing the access unit of the first network system, the terminal may perform a voice service. The access unit of the first network system may collect access service information for an accessed terminal while providing a voice service, and may periodically detect whether the voice service is ended, and when it is detected that the terminal ends the voice service, may determine whether to perform an operation of switching the terminal from the first network system to the second network system based on the recorded access service information.
Optionally, the determining, based on the access service information, whether to switch the terminal from the first network system to the second network system to which the terminal has access history may include: if the access information meets the preset access condition, the interoperation information meets the preset switching requirement, the voice service information meets the recording requirement, and the data service information meets the preset service flow threshold, determining to switch the terminal from the first network system to the second network system; otherwise, determining to reside the terminal in the first network system.
If the access type in the access information is idle access or handover access, that is, the terminal is accessed from an idle state or switched access in a connected state, and the access reason is a reason falling back from the second network system, it can be determined that the preset access condition is satisfied; the terminal in the interoperation information supports residence of different frequency bands under the second network system and supports switching to the second network system in a connected state, and then the interoperation information is determined to meet a preset switching requirement; if the recording of various information in the voice service information is successful, determining that the voice service information meets the recording requirement; the service flow in the data service information is greater than or equal to a preset service flow threshold value in continuous time, and the preset flow threshold value can be set according to actual conditions. When the conditions are met, the terminal can be determined to be switched from the first network system to the second network system, namely, the terminal is quickly returned to the second network system; when any one of the above conditions is not satisfied, it is determined to camp the terminal on the first network system.
In the above scheme, through comprehensive recording of multi-dimensional information after the terminal is accessed into the first network system, judgment of whether the terminal returns to the historical network system after the voice service is finished is more accurate, a judgment error caused when the terminal is judged only according to an access reason in the existing scheme is avoided, judgment accuracy is improved, the condition of the terminal service is considered, frequent interoperation under different mobile communication systems when the network throughput is small is avoided, the terminal is made to reside in the current more suitable network system, and the throughput efficiency and the resource utilization rate of the whole communication system are improved.
Optionally, there are two ways for the terminal to access the first network system, specifically referring to fig. 2 and fig. 3. Fig. 2 is a schematic diagram of a terminal accessing a first network system according to an embodiment of the present disclosure, and as shown in fig. 2, the terminal directly initiates Radio Resource Control (RRC) connection establishment to an access unit of the first network system, and carries an access reason in a message of the RRC connection establishment, where the access reason may include a calling voice, a called voice, a signaling, an emergency call, a Circuit Switched Fallback (CSFB), and the like, and is not limited specifically. Fig. 3 is a schematic diagram of another terminal accessing a first network system according to an embodiment of the present disclosure, where the terminal is directly switched from a second network system to the first network system in a connected state, and a hand-in reason is carried in a hand-in request signaling, where the hand-in reason may include hand-in based on air interface quality or hand-in based on an evolved packet system Fallback (EPS Fallback) reason, and the specific details are not limited. The access unit of the first network system may record the access reason or the hand-in reason.
And 102, if so, determining a target cell for network switching, and switching the terminal from the first network system to a target cell in a second network system.
Specifically, when the access unit of the first network system determines to switch the terminal from the first network system to the second network system to which the terminal has historically accessed based on the access service information, a target cell for network switching may be determined first, and the terminal may be switched from the first network system to the target cell in the second network system.
Optionally, determining a target cell for network handover may include: and determining the cell with the highest switching success rate or the source cell as a target cell based on historical network switching information and/or real-time measurement information corresponding to the second network system, wherein the historical network switching information comprises preset number of cell information with the historical switching success rate ranking in the second network system. The target cell refers to a corresponding access cell for network handover or network return in the second network system. The real-time measurement information refers to a measurement result obtained by performing signal measurement on a cell in the first network system, and the real-time measurement information may include various parameters, such as signal strength and signal quality. The handover success rate may be a ratio between the handover success number and the handover initiation number.
After determining that the terminal is switched from the first network system to the second network system, the access unit of the first network system can determine whether to perform network switching based on measurement operation through the operation maintenance unit, if not, historical network switching information is obtained, whether a source cell in the second network system accessed by the historical terminal is in a cell with the top rank in the historical network switching information is judged, and if yes, the source cell is determined to be a target cell; otherwise, the cell with the highest switching success rate is determined as the target cell. If network switching is performed based on measurement operation, measurement configuration may be performed on a set number of cells with a switching success rate ranked higher in the first network system, and a cell with an optimal signal may be determined as a target cell based on the obtained real-time measurement information.
The terminal has two states after accessing to the first network system through the access unit, one is an idle state, and in this state, the terminal only needs to decode the paging channel at regular time with a relatively long paging cycle to check whether a trigger service needs to be carried out; the other is a connection state, in which a radio bearer connection is established between the terminal and the access network, and the access network equipment performs interaction of uplink and downlink data with the terminal through authorization and resource allocation with short time delay. Because the quality of the air interface wireless environment changes along with the movement of the terminal or the change of other objective environments, the access unit has different modes when judging the target cell which returns quickly, can select the source cell of the second network system which resides in history for returning, can select the target cell for returning based on blindness based on the configuration of the current access unit, and can also perform measurement configuration by the access unit, report candidate target cells through the terminal, and select the optimal target cell for returning quickly.
In this embodiment of the present disclosure, before switching the terminal from the first network system to the target cell in the second network system, the method may further include: and determining a target mode of network switching, wherein the target mode is a switching mode or a redirection mode. Optionally, determining a target mode of network handover may include: if the switching interface exists between the first network system and the second network system, determining that the target mode is a switching mode; otherwise, determining the target mode as a redirection mode.
Since it has been determined in the previous step that the terminal supports handover to the second network system, if a handover interface between core networks exists between the first network system and the second network system, it may be determined that the target mode is a handover mode; if the switching interface between the core networks does not exist between the first network system and the second network system, the target mode can be determined to be the redirection mode.
In an implementation of the present disclosure, the switching the terminal from the first network system to the target cell in the second network system may include: and switching the terminal from the first network system to a target cell in the second network system based on the target mode. When the target mode is a switching mode, the terminal can be switched from the first network system to a target cell in the second network system in a connection mode switching mode. And when the target mode is a redirection mode, sending the resource release message to the terminal so that the terminal reselects the target cell in the second target network system based on the resource release message after switching from a connection state to an idle state, wherein the resource release message comprises cell information of the target cell, such as cell frequency points, identifiers and the like of the target cell.
Exemplarily, fig. 4 is a schematic diagram of a terminal network handover provided by the embodiment of the present disclosure, and fig. 4 represents a network handover process when a target mode is a redirection mode, and as shown in fig. 4, the network handover process may specifically include: in a first network system, when a voice service is finished, an access unit receives a command of a network side to release a voice bearer or a session stream, at this time, a terminal is in a connected state in the first network system, the access unit of the first network system directly sends an RRC release message to the terminal, the terminal is converted from the connected state to an idle state by carrying information such as a frequency point of a target cell, a cell identifier and the like in the release message, and after receiving the release message, the terminal preferentially selects the frequency point specified in the release message and the target cell corresponding to the cell identifier to reselect and reside. However, releasing the connected terminal to the idle state may cause interruption of the currently ongoing data service, which may affect the service experience of the user.
Fig. 5 is a schematic diagram of another terminal network handover provided in the embodiment of the present disclosure, where fig. 5 represents a network handover process when a target mode is a handover mode, and as shown in fig. 5, the network handover process may specifically include: after the access unit of the first network system determines the target cell, the terminal is switched to the target access unit of the second network system in a connection state switching mode. As shown in fig. 5, the handover procedure involves interoperation between different communication network systems, and whether the terminal supports handover between different network systems, access network capability, and support capability of core networks of different network systems need to be considered, and the terminal can be quickly returned to the second network system through the handover mode only when all the terminals support handover. For example, when the 2/3G system interoperates with the 4G system, whether a Mobile Switching Center (MSC) of the 2/3G core network supports the capability of handover to a Mobility Management Entity (MME) of the 4G core network; 4. when the 5G system is switched, whether an N26 interface between the MME and the amf (action Message format) exists or not and whether the capability of switching when the N26 interface does not exist is supported need to be considered. The data service currently carried out by the terminal cannot be interrupted in a switching mode, and better service continuity experience can be brought.
In the embodiment of the present disclosure, while providing a voice service, an access unit of a first network system may collect information such as different types of traffic volumes and air interface quality of a terminal, and simultaneously, in combination with historical return success rate information in the first network system, select a cell frequency point or a cell of a second network system in an optimal candidate to perform measurement, and finally select a redirection or handover mode to quickly return the terminal to an optimal target cell. The success rate of quick return of the system, the throughput of the whole network of the system and the utilization efficiency of air interface resources are improved, the interference between systems is reduced, the problem of the existing scheme is solved, and the user experience is guaranteed.
The embodiment of the disclosure can select a better second network system as much as possible to reside and provide services under the condition that the service characteristics are satisfied, and when the service characteristics are satisfied that the resident first network system is more optimized than the resident second network system, the second network system is not selected to return and is selected to continuously reside in the network system, and the selection of the network system after the voice service is finished when the access terminal is accessed in the first network system is optimized through the judgment of the access type of the terminal in the first network system and the judgment of the access terminal capability and the access core network (including the first network system core network and the second network system core network).
According to the network communication scheme provided by the embodiment of the disclosure, when the terminal is detected to finish the voice service, whether the terminal is switched from a first network system to a second network system which is accessed by the terminal in history is judged based on the access service information; and if so, determining a target cell for network switching, and switching the terminal from the first network system to the target cell in the second network system. By adopting the technical scheme, the first network system can judge whether to return to the second network system or not through the recorded access service information of the terminal after providing the voice service, the judgment accuracy of whether the terminal returns or not after the voice service is improved because the access service information relates to more comprehensive access and service characteristic information, and the failure of return caused by unreasonable parameters or wrong cell selection in the second network system is avoided through the determination of the target cell, so that the success rate of network switching is improved, the overall network throughput and the resource use efficiency of the system are further improved, and the user service experience is optimized.
Fig. 6 is a schematic flow chart of another network communication method provided in the embodiment of the present disclosure, and the embodiment further optimizes the network communication method on the basis of the above embodiment. As shown in fig. 6, the method includes:
The terminal enters an access unit of the first network system, the access unit records a terminal access reason Type1 and an access Type2, and when the access Type is handover access, the source cell S of the second network system can be recorded.
For a terminal accessed to a first network system, an access unit records the time T1 of terminal access, records whether to initiate establishing a voice service bearer or a session flow Flag1 and the time T2 of initiating voice; for terminals that hand in to the access unit, the access unit records whether there is a hand in Flag2 that carries the voice bearer and the voice session flow, and if so, T1 is the same time as T2. The Flag1 is used as the access scene of the terminal from the idle state, and the Flag2 is used as the cut-in scene of the terminal from the connected state, and can be combined into the same Flag bit.
The access unit records the interoperation capability information interacted between the terminal and the core network, and may include whether to support the resident C1 of different frequency bands in the second network system, whether to support the handover to the second network system in a connected state C2, and whether to have an interface Flag3 between the core networks of the first network system and the second network system, where the first network system core network element selected by the current terminal feeds back whether to have interface information between the core networks of the first system and the second system, which may be used as a decision of another terminal.
The access unit records whether a voice service signaling plane normally establishes Flag4, whether data plane connection normally establishes Flag5, records voice service connection ending time T3, whether packet data plane service Flag6, record period statistics data plane throughput Thr and service flow in continuous time exist at the same time.
After the core network initiates voice service, a protection Timer is started, the duration can be configured through Operation Administration and Maintenance (OAM), and continuously counted Thr.
The access unit determines whether the Timer of the protection Timer is overtime, if not, the access unit returns to continue determining whether the Timer is overtime, and if yes, step 207 is executed.
The access unit makes a quick return judgment, and the input information comprises: type1, Type2, T1, T2, T3, C1-C2, Flag 1-6 and Thr, and whether to perform quick return interoperation is judged. Specifically, the access cause Type1 is a fallback cause from the second network system, the access Type2 is an idle access or handover access Type, and a voice Flag1 or Flag2 is established in the connection maintaining process; establishing a normal voice signaling plane connection Flag4 and a Flag5 based on data plane connection in the first network system, wherein after the voice in the first network system is finished through T1, T2 and T3, the traffic flow is greater than a certain threshold value within the connection duration, namely a preset traffic flow threshold value; and the terminal supports the camping C1 of different frequency bands in the second network system and supports the switching C2 to the second network system in the connected state, and when the above conditions are met, it can be determined to perform quick return, and step 208 or step 209 is executed. When any of the above conditions is not satisfied, step 211 is performed.
The access unit selects whether to operate based on the measurement configuration when deciding to perform a quick return. Specifically, the measurement-based quick return or the measurement-free quick return may be selected according to the configuration of the operation and maintenance unit, and if the measurement-free quick return is performed, step 208 is executed; if a measurement-based interoperation is selected, step 209 is performed.
And step 208, determining the target cell without quick return based on the measurement.
Selecting quick return which is not based on measurement, selecting cell frequency points and cell identifiers with the rank of the initiating times and the successful times which are listed in the historical interoperation information, directly checking whether the source cell S is in a list with the rank at the top, and if so, determining the source cell S as a target cell; otherwise, selecting the first-ranked cell frequency point from the list and determining the cell corresponding to the cell identifier as the target cell.
Optionally, if the source cell S is not in the top list, step 209 may be further performed to determine the target cell based on the real-time result of the measurement, so as to improve the accuracy of cell selection.
And step 209, based on the measurement quick return, determining the target cell.
And based on the quick return of measurement, selecting the target cell frequency points and cell identifications with the rank of the initiating times and the success times which are listed in the historical interoperation information for measurement, and determining the optimal cell as the target cell based on the measurement result.
And step 210, determining a target mode of quick return.
The target mode is a switching mode or a redirection mode. Specifically, on the basis that it is determined in step 207 that the terminal supports the camping C1 in different frequency bands in the second network system and supports the handover to the second network system in the connected state C2, if it is determined that an interface Flag3 exists between the core networks of the first network system and the second network system, it may be determined that the target mode is the handover mode; if the terminal does not support the camping C1 of different frequency bands in the second network system, does not support the switching C2 to the second network system in the connected state, or does not have the interface Flag3 between the core networks of the first network system and the second network system, it may be determined that the target mode is the redirection mode.
And step 211, performing quick return according to the determined target mode and the target cell.
And the access unit switches the terminal from the first network system to a target cell of the second network system in a determined target mode.
And step 212, finishing the processing.
Fig. 7 is a schematic diagram of network communication provided in an embodiment of the present disclosure, where the specific process may include: accessing a terminal; establishing process information acquisition; voice access process and information acquisition; quickly returning to judgment after the voice is released; selecting an interoperation type; and selecting a target cell. The fast return interoperation is performed.
When different network systems coexist and a more advanced second network system cannot provide voice service for the terminal, the terminal returns to the first network system for voice service, and in the first network system, when the voice service is finished, the method for performing optimization decision processing on the terminal to select different network systems to reside specifically comprises the following steps: recording access reasons and types of a terminal accessed to a first network system, including access from an idle state and cut-in from a second communication access unit in a connection state, recording capability information related to mobile interoperation interacted between the terminal and a core network of the first network system in a connection establishment process after the terminal is accessed, wherein the capability information includes whether the terminal supports residence of the second network system (different frequency bands), whether a mobile interoperation interface between the currently selected access core network and the core network of the second network system exists, and whether the terminal supports cut-in to the second network system in the connection state; recording terminal access time, and collecting terminal service behaviors, including whether a voice service is established in a certain time range, whether a voice service signaling plane is normally interacted, whether a voice service data plane is normally used for uplink and downlink data transmission and the duration of voice service data transmission, whether a packet data service, the duration of the packet data service and throughput exist at the same time, and the like; after the voice service under the first network system is finished, the terminal is quickly returned to the terminal through the recorded information to make a decision, and the connection with the finished voice is quickly returned to the terminal under the condition of meeting the access type, the terminal and network capacity, the access service volume and the air interface requirement; after the decision is made to return to the second network system quickly, the terminal and the network side capability are selected to return to the second network system quickly, interoperation is carried out in a redirection or switching mode, in the target cell selection process, candidate frequency points or cells with high success rate are selected from the historical quick return candidate cell frequency points and the identification list to be measured, and under the condition of a full measurement threshold, the optimal target second network system access unit cell is selected to carry out interoperation return.
The method of the embodiment of the present disclosure may be applied to network systems of 3G, 4G, or 5G systems, and for example, may be applied to drop from 4G to 2/3G when 2/3G and 4G systems coexist, and make a 2/3G decision to return to 4G quickly; the method can also be applied to coexistence of 4G and 5G systems, drop-back of 5G to 4G, quick return of 4G decision to 5G and the like.
In the conventional fast return method after voice fallback, there are terminal-autonomous fast return and network-assisted fast return, where the network-assisted fast return policy also needs to have a first network system capable of identifying that the current service connection is a residence initiated due to voice fallback, which needs higher protocol version and support of signaling information codec, and even if the policy for fast return is selected under this condition, there is only a policy for simply redirecting a target cell frequency point and a cell, and current terminal service characteristics, such as whether packet data service exists or not and the uplink and downlink packet data service volume in the current system, are not considered.
The network communication scheme provided by the embodiment of the disclosure optimizes the analysis method of voice fallback or fast return of a terminal based on coverage fallback after the voice service is finished, records the access reason and the interaction process of key capacity of access, counts the service conditions (including whether the voice service is initiated or not, whether the signaling plane of the voice service is normally interacted, whether the data plane of the voice service is normally transmitted by uplink and downlink data, the duration of voice service data transmission, whether packet data service exists at the same time, the duration and throughput of the packet data service, and the like) in a first network system, decides whether to fast return to a second network system or not according to the information, selects fast return through redirection or switching, optimizes the selection of a target return cell on the premise of fast return decision, and counts and collects the success times of historical return to the cells of the second network system, the method can avoid frequent interoperation under different mobile network systems when the network throughput is low, can also optimize the occurrence of a return failure result caused by selecting wrong target frequency points and cells due to unreasonable configuration parameters of different second network system frequency points and cells, improves the success rate of system interoperation, and further improves the throughput of the whole system and the user service experience.
