Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only a part of the structures related to the present invention, not all of the structures, are shown in the drawings, and furthermore, embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
Example one
Fig. 1 is a flowchart of a network transmission performance adjusting method according to an embodiment of the present invention, where the embodiment is applicable to a case of adjusting a network transmission performance parameter of a 5G NR system, and the method may be executed by a network transmission performance adjusting apparatus, and the apparatus may be implemented by software and/or hardware.
As shown in fig. 1, the method specifically includes the following steps:
and step 110, when the terminal user does not access the 5G NR system for the first time and the positioning function enabling state of the terminal user is the starting positioning function, the base station acquires the position information of the terminal user and sends the position information to the performance server through the core network.
In this embodiment, the network transmission performance adjusting method is applied to a 5G NR system, which includes a base station, a core network, and a performance server.
The positioning function enabling state can represent whether the terminal user has the positioning function, the positioning function enabling state can be divided into a positioning function starting state and a positioning function non-starting state, the positioning function starting state means that the terminal user has the positioning function, and the positioning function non-starting state means that the terminal user does not have the positioning function. The position information of the terminal user can be collected and determined by a positioning device on the terminal equipment and can be embodied as longitude and latitude information.
Specifically, when the terminal user accesses the 5G NR system, the core network may determine that the terminal user is successfully accessed, notify the performance server to update the user state of the terminal user to an online state, and when the base station determines that the location function enabling state of the terminal user is the location function enabled state, obtain the location information of the terminal user, and send the location information to the performance server through the core network, so as to determine the initial performance parameter.
The initial performance parameters may include an initial PDCCH aggregation level, uplink and downlink MCS parameters, and the like. The historical location performance information may include a historical location and historical performance parameters of the terminal, and may be historical locations and corresponding historical performance parameters of different terminals in a previous online state of the terminal user.
Optionally, before the performance server determines the initial performance parameter according to the location information and by combining the historical location performance information of the end user, the following steps may be performed: and the performance server forms a fitting curve of the terminal position and the performance parameters according to the historical position performance information of the terminal user.
Optionally, the performance server determines the initial performance parameter according to the location information and by combining historical location performance information of the terminal user, and may perform the following steps: and the performance server determines the fitting performance parameters corresponding to the position information by using the fitting curve, and determines the fitting performance parameters as initial performance parameters.
Specifically, after the terminal user accesses the 5G NR system, the base station may continuously upload the location information of the terminal user and the corresponding performance parameters when the location function is enabled, and the performance server may store the data, that is, the historical location performance information of the terminal user, and establish a functional relationship between the historical location of the terminal in the historical location performance information and the historical performance parameters, and perform function fitting to obtain a fitting curve of the terminal location and the performance parameters. When the terminal user does not access the 5G NR system for the first time, the performance server can determine the fitting performance parameter suitable for the position information of the terminal user at the current moment according to the fitting curve after acquiring the position information of the terminal user, and the performance server determines the fitting performance parameter as the initial performance parameter and sends the initial performance parameter to the base station.
For example, fig. 2 is a schematic diagram of a network transmission performance adjustment method according to an embodiment of the present invention. As shown in fig. 2, after the UE is disconnected, the UE is connected to the network again, and then login authentication information is sent to the core network for authentication, after the core network determines that the UE is successfully accessed, the core network sends a UE connection notification to the performance server and carries information that the UE starts a positioning function, at this time, the performance server does not immediately send an initial performance parameter to the base station, but waits for the base station to obtain the location information of the UE, and after the UE is sent to the performance server through the core network, the performance server can determine the initial performance parameter corresponding to the location information according to the location information, and then perform performance parameter sending operation.
The network measurement parameter may be actually measured parameters such as inner loop CQI and outer loop bler.
Specifically, the initial performance parameters determined by the performance server are obtained by fitting according to historical empirical values and approximately conform to the position of the terminal user at the current time, so that the base station can obtain the network measurement parameters of the terminal user, and the initial performance parameters are finely adjusted based on the network measurement parameters.
According to the technical scheme of the embodiment, when the terminal user is not accessed to the 5G NR system for the first time and the positioning function enabling state of the terminal user is the starting positioning function, the base station acquires the position information of the terminal user and sends the position information to the performance server through the core network, the performance server determines the initial performance parameters according to the position information and the historical position performance information of the terminal user, the initial performance parameters are sent to the base station through the core network, the historical position performance information comprises the historical position of the terminal and the historical performance parameters, the base station acquires the network measurement parameters of the terminal user, and the initial performance parameters are adjusted based on the network measurement parameters. When a terminal user accesses the system, the initial performance parameters can be determined by combining historical experience values instead of using the initially configured performance parameters, and then the initial performance parameters are finely adjusted, so that the performance parameters can be rapidly and accurately determined, and the experience effect of the user on terminal disconnection and reconnection is better.
Example two
Fig. 3 is a flowchart of a network transmission performance adjusting method according to a second embodiment of the present invention. On the basis of the above embodiments, the present embodiment further optimizes the network transmission performance adjusting method.
As shown in fig. 3, the method specifically includes:
The information table is used for storing the terminal identification code and the historical position performance information. The terminal identification code may be the international mobile subscriber identity UE IMSI of the terminal.
Specifically, after receiving the end user online notification, the performance server creates an information table of the end user if it is determined that the end user is online for the first time. The information table may include UE IMSI, positioning function enabled status, longitude and latitude records, PDCCH aggregation level, uplink and downlink MCS, etc.
Exemplarily, fig. 4 is a schematic diagram of a first principle of a network transmission performance adjustment method according to a second embodiment of the present invention, as shown in fig. 4, a terminal user UE is online and sends login authentication information to a core network for authentication, after the core network determines that the UE is successfully accessed, the core network sends a UE online notification to a performance server, and after the performance server receives the UE online notification, if it determines that the UE is online for the first time, an information table of the UE is created.
The preset performance parameter may be a preset performance parameter value, and the value may be set according to experience.
Specifically, when the terminal user accesses the 5G NR system for the first time, the performance server determines the preset performance parameter as the initial performance parameter and sends the initial performance parameter to the base station.
And step 230, updating the historical position performance information in the information table when the performance updating condition is met.
Optionally, the performance update condition may include an event trigger condition and a periodic reporting condition; the event triggering condition can be that the performance parameter floating value is greater than or equal to a preset floating threshold value; the periodic reporting condition may be a preset periodic time period away from the last time the periodic reporting condition is satisfied.
In this embodiment, there may be two conditions for triggering performance update, one is an event trigger condition, and the other is a periodic reporting condition. The performance parameter is updated after an event triggering condition is triggered, where the event triggering condition may be triggered when the modulation order of the MCS differs by 2 steps. The periodic reporting condition is to periodically trigger according to a preset periodic time period, the set periodic time may be longer in an indoor wireless broadband scenario, and the periodic time may be shorter in a mobile scenario.
Specifically, the updating of the historical location performance information in the information table can be performed in two cases:
the first condition is as follows: if the positioning function enabling state of the terminal user is the starting positioning function, the base station acquires the current position information and the current performance parameters of the terminal user and sends the current position information and the current performance parameters to the performance server through the core network, and the performance server stores the current position information and the current performance parameters as a group of historical position performance information into an information table of the terminal user.
For example, fig. 5 is a schematic diagram illustrating a second principle of a network transmission performance adjusting method according to a second embodiment of the present invention, as shown in fig. 5, when a base station is triggered by an event or a periodic reporting time is up, if a UE starts a positioning function, first obtaining current location information from a UE side, and then sending the current location information, current performance parameters such as a PDCCH aggregation level and an uplink and downlink MCS to a core network. The core network reports the current position information and the current performance parameters to a performance server, and the performance server updates a UE information table.
Case two: if the terminal user has no positioning function, the base station acquires the current performance parameters of the terminal user and sends the current performance parameters to the performance server through the core network, and the performance server stores the current performance parameters as historical performance parameters into an information table of the terminal user.
If the UE has no positioning function, the performance parameters can be directly reported, namely the position information is invalid, the current performance parameters such as PDCCH aggregation level, uplink and downlink MCS and the like are reported to the performance server through the core network, and the performance server updates the UE information table.
Specifically, the end user disconnection can be divided into two cases, one is that the end user actively registers, and the other is that the network registers. Fig. 6 is a third schematic diagram of a network transmission performance adjusting method according to the second embodiment of the present invention, and fig. 6 is an information interaction diagram of an end user actively registering. When the terminal initiatively de-registers, after the core network replies that de-registration is successful, a UE disconnection notification is sent to the performance server, after the performance server receives the notification, the UE state is updated to be a disconnection state, and meanwhile, the last updated historical performance parameters are recorded, namely the performance parameters before the UE is disconnected are the disconnection performance parameters.
Fig. 7 is a fourth schematic diagram of a network transmission performance adjusting method according to a second embodiment of the present invention, and fig. 7 is an information interaction diagram for network de-registration. And after receiving the notification, the performance server updates the UE state to the offline state and simultaneously records the last updated historical performance parameter, namely the performance parameter before the UE is offline is the offline performance parameter.
In this embodiment, when the end user comes online again, step 250 or step 260 may be performed as appropriate.
And step 250, when the terminal user is not accessed into the 5G NR system for the first time and the positioning function enabling state of the terminal user is the starting positioning function, the base station acquires the position information of the terminal user and sends the position information to the performance server through the core network, and the performance server determines the initial performance parameters according to the position information and the historical position performance information of the terminal user and sends the initial performance parameters to the base station through the core network.
After step 250, step 270 may continue.
And step 260, when the terminal user does not access the 5G NR system for the first time and the positioning function enabling state of the terminal user is a non-positioning function, the performance server issues the offline performance parameter as an initial performance parameter to the base station.
Specifically, when the terminal user does not access the 5G NR system for the first time and the positioning function enabling state of the terminal user is the no positioning function, the last updated historical performance parameter before the last disconnection of the terminal user, that is, the last disconnection performance parameter of the last disconnection may be issued to the base station as the initial performance parameter.
Exemplarily, fig. 8 is a schematic diagram of a fifth principle of a network transmission performance adjustment method according to the second embodiment of the present invention, as shown in fig. 8, after the UE is disconnected and connected to the network again, and the core network determines that the UE is successfully connected to the network, the performance server sends a notification that the UE is connected to the network, and carries information that the UE does not have a positioning function, so that the performance server can send the disconnection performance parameter as an initial performance parameter to the core network, and the core network forwards the initial performance parameter to the base station.
After step 260, step 270 may continue.
According to the technical scheme of the embodiment, when a terminal user accesses a 5G NR system for the first time, a performance server creates an information table of the terminal user, and the performance server determines a preset performance parameter as an initial performance parameter and sends the initial performance parameter to a base station; when the performance updating condition is met, updating the historical position performance information in the information table; when the performance server receives a user disconnection notification of the terminal user, updating the user state of the terminal user into a disconnection state, and determining the last updated historical performance parameter as a disconnection performance parameter; when the terminal user is not accessed to the 5G NR system for the first time and the positioning function enabling state of the terminal user is the starting positioning function, the base station acquires the position information of the terminal user and sends the position information to the performance server through the core network, and the performance server determines initial performance parameters according to the position information and the historical position performance information of the terminal user and sends the initial performance parameters to the base station through the core network; when the terminal user is not accessed to the 5G NR system for the first time and the positioning function enabling state of the terminal user is a non-positioning function, the performance server issues the offline performance parameter as an initial performance parameter to the base station; the base station acquires network measurement parameters of the terminal user and adjusts the initial performance parameters based on the network measurement parameters. When the terminal user accesses the terminal again, if the terminal user starts the positioning function, the initial performance parameter is determined by combining the historical experience value and is sent to the base station, if the terminal user does not have the positioning function, the initial performance parameter determined by the performance parameter before the user drops off the line last time is sent to the base station, whether the terminal user has the positioning function or not can be determined accurately, the initial performance parameter can be finely adjusted, and the experience effect of the user on the terminal dropping off and the terminal re-getting on-line is better.
