Description

Base station implementation method and device, base station and storage medium
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for implementing a base station, a storage medium, and a computer program product.
Background
The simulation base station is a wireless device for acquiring international mobile subscriber identification code IMSI (International Mobile Subscriber Identity) information of a public network mobile subscriber in a specific local area such as an important traffic intersection and a traffic junction aiming at public safety.
The existing emulated base station will set the operator's public land mobile network PLMN (Public Land Mobile Network), frequency point and physical cell identity PCI (Physical Cell Identifier). At this time, the tracking area code TAC (Tracking Area Code) of the emulated base station is not the same as the planning value of the operator's existing network. When the mobile user is in an idle state and passes through the simulation base station, the tracking area code TAC of the simulation base station can cause the user terminal UE (User Equipment) to reselect and initiate a TAC update request, and in the process, the simulation base station requests the UE to report the user information, so that the user information is acquired.
However, the emulated base station can have a significant negative impact on operator network structure and performance. When the simulation base station works, the signals of the simulation base station interfere with surrounding current network cells, so that the signal-to-interference-plus-noise ratio SINR (Signal to Interference plus Noise Ratio) of the surrounding area is poor, the downloading rate of the surrounding users is reduced, and the disconnection rate is high. Meanwhile, during the period that the idle state user reselects to the simulated base station, the idle state user cannot be paged when the user is called, and cannot initiate a call when the user is called, and the connection state user can be switched by mistake and dropped in the coverage area of the simulated base station.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The implementation method of the base station provided by the embodiment of the application can be applied to an application environment shown in fig. 1. Wherein the user terminal UE102 communicates with the public network base station 104 through a communication network. The core network may send the data to be exchanged to the public network base station 104, or may accept the data sent by the public network base station to the core network. Wherein the user terminal UE102 may be, but is not limited to, various mobile terminals, wireless terminals and portable wearable devices. The portable wearable device may be a smart watch, smart bracelet, headset, or the like. The public network base station 104 may be implemented by an independent base station or a base station cluster formed by a plurality of base stations.
In one embodiment, as shown in fig. 2, a method for implementing a base station is provided, and the method is applied to the public network base station in fig. 1 for illustration, and includes the following steps:
step S202, a real tracking area code and a virtual tracking area code which are preconfigured by a public network base station are obtained; the real tracking area code is used for interfacing with a core network.
The public network base station is a public mobile communication base station, and the public network base station can configure a real tracking area code to locate the user terminal UE, so that the user terminal UE within the coverage range of the public network base station is located. It should be appreciated that the real tracking area code may be connected to the core network. After the real tracking area code is connected with the core network, if the public network base station adopts the real tracking area code to establish communication connection with the user terminal UE, at this time, the user terminal UE can complete connection between the user terminal UE and the core network according to the real tracking area code.
The public network base station adopting the virtual tracking area code cannot be connected with the core network. Therefore, after the UE is communicatively connected to the public network base station that adopts the virtual tracking area code, the UE cannot be connected to the core network. At this time, the public network base station adopting the virtual tracking area code becomes a simulation base station which cannot be connected with the core network, and the simulation base station adopting the real tracking area code becomes a public network base station which can be connected with the core network. That is, if the base station uses a true tracking area code, the base station may be referred to as a public network base station; if a base station uses a virtual tracking area code, the base station may be referred to as an emulated base station.
Specifically, according to the corresponding requirement of the user simulation base station, the public network base station can read at least two preset tracking area codes, wherein one tracking area code is a real tracking area code which can be connected with the core network, and the other one or more tracking area codes are virtual tracking area codes which are not connected with the core network.
Step S204, the real tracking area code and the virtual tracking area code are alternately broadcasted to the user terminal UE according to a preset time period.
Because the simulation base station causes the user terminal UE to reselect by broadcasting the virtual tracking area code, the user terminal UE reselects to the simulation base station corresponding to the virtual tracking area code. At this time, the simulation base station can acquire the user information reported by the user terminal UE, thereby achieving the purpose of acquiring the user information.
However, when the dummy base station broadcasts the virtual tracking area code, the user terminal UE in an idle state in the coverage cell of the base station cannot be connected to the core network at this time. Therefore, the virtual tracking area code and the real tracking area code need to be broadcasted alternately according to a preset time period, so that the base station is ensured to be used as a simulation base station and a public network base station alternately in the process of broadcasting the virtual tracking area code and the real tracking area code alternately. When the base station is a public network base station, the user terminal UE in an idle state can be connected to the core network.
Specifically, a preset time period is set, and the public network base station circularly and alternately broadcasts the real tracking area code and the virtual tracking area code to the user terminal UE according to the time period and the sequence. When broadcasting the virtual tracking area code, the simulation base station starts to collect user information; and when the real tracking area code is broadcast, the public network base station provides network service for the user terminal UE. For example, alternating every one minute, the first minute broadcasts the real tracking area code and the second minute broadcasts the virtual tracking area code.
Step S206, in the time period of broadcasting the virtual tracking area code to the UE, if a tracking area code update request sent by the target UE in an idle state is received, after receiving the user information sent by the target UE, a reject tracking area code update message is sent to the target UE.
It should be understood that the target user terminal UE in idle state may be understood as a terminal currently having no call service and a data download service based on an operator network. After receiving the system message of the tracking area code different from the surrounding base station, the target user terminal UE in the idle state can cause the target user terminal UE to initiate reselection and initiate a tracking area code update request. Therefore, in the case that the virtual tracking area code is broadcast by the emulation base station, the target user terminal UE in the idle state may send a tracking area code update request to the emulation base station, and at this time, the emulation base station may acquire the user information of the target user terminal UE and reject the tracking area code update request of the target user terminal UE.
Wherein the tracking area code update request is used for repositioning the target user terminal UE, and the target user terminal UE is in communication connection based on the reselected base station. The user information may be location data of the target user terminal UE, and terminal information of the target user terminal UE, for example, international mobile subscriber identity IMSI information. The idle target UE always accepts the system broadcast message and waits for the called, and has no call and data download service. The target UE is usually an idle UE within the area covered by the public network base station, and based on this, the public department can collect the user information in a specific area (such as important traffic intersections and traffic junctions).
It should be appreciated that during the period when the emulated base station broadcasts the virtual tracking area code, the user terminal UE in the connected state does not read the system message in the service handover. Therefore, the user terminal UE in the connection state does not initiate reselection due to the change of the tracking area code in service switching, and therefore the tracking area code updating request is not sent to the simulation base station. In summary, the UE in the connected state is not affected by the virtual tracking area code during service handover.
Specifically, the simulation base station (the simulation base station is a simulation base station simulated by a public network base station) is in a time period of broadcasting a virtual tracking area code to the user terminal UE. The target user terminal UE in an idle state sends a tracking area code updating request to the simulation base station, the simulation base station receives the request and acquires user information of the target user terminal UE, and sends a tracking area code updating refusing message to the target user terminal UE, so that the tracking area code updating request is refused.
In the implementation method of the base station, two tracking area codes are configured for the public network base station, wherein one tracking area code can be connected with the core network, and the other tracking area code is a virtual tracking area code. Therefore, the public network base station can provide service of an operator through the real tracking area code, and the public network base station can also become a simulation base station through the virtual tracking area code, so that user information is collected. It should be understood that, during the period of broadcasting the virtual tracking area code to the UE, the simulated base station of the public network base station can receive the user information of the UE in the idle state, thereby completing the collection of the user information. Based on the method, the real tracking area code and the virtual tracking area code are broadcast in a polling mode, so that an operator can provide stable service for the user terminal UE in the polling process, and the simulation base station can also be ensured to collect user information of the user terminal UE. In summary, compared with the prior art, the technical scheme of the application can achieve the effect of improving the network quality of operators while the public network base station takes account of public department information acquisition.
In one embodiment, as shown in fig. 3, the specific implementation procedure of the step of alternately broadcasting the real tracking area code and the virtual tracking area code to the UE according to a preset time period includes:
in step S302, in a first time period, a system message SIB1 carrying the real tracking area code is broadcasted to the user terminal UE.
When broadcasting to user terminal UE, the public network base station can store the real tracking area code into the system message SIB1, and broadcast the system message SIB1 to achieve the effect of broadcasting the real tracking area code. The preset time period can be divided into a first time period and a second time period, wherein the public network base station can broadcast the real tracking area code in the first time period, and the simulation base station changed from the public network base station can broadcast the virtual tracking area code in the second time period.
Specifically, the public network base station may broadcast, to the user terminal UE in the coverage area of the base station, a system message SIB1 storing the real tracking area code in a preset first time period.
In step S304, in a second time period, a system message SIB1 carrying the virtual tracking area code is broadcasted to the user terminal UE.
When the simulation base station changed from the public network base station broadcasts to the user terminal UE, the virtual tracking area code can be stored in the system message SIB1, and the effect of broadcasting the real tracking area code is achieved by broadcasting the system message SIB1.
Specifically, the simulation base station changed from the public network base station may broadcast the system message SIB1 storing the virtual tracking area code to the user terminal UE in the coverage area of the base station in a preset second time period.
Optionally, the public network base station may store the real tracking area code in other system messages when broadcasting to the UE; the virtual tracking area code may be stored in other system messages, for example, MIB messages, SIB2, SIB3, etc., when broadcast to the user terminal UE by the emulating base station changed from the public network base station.
Step S306, after the second time period is over, the step of broadcasting a system message SIB1 carrying the real tracking area code to the UE in a first time period is performed, where the first time period is greater than the second time period.
After the second time period is over, returning to the first time period, the steps S302 and S304 are alternately and circularly executed. At this time, the public network base station or the simulation base station changed from the public network base station can continuously and alternately broadcast the real tracking area code and the virtual tracking area code. It should be appreciated that, because the need for the emulation base station to broadcast the virtual tracking area code is not as high as the need for the public network base station to broadcast the real tracking area code, the public network base station is more required to broadcast the real tracking area code for a long time. Based on this, the first time period is greater than the second time period.
In this embodiment, by setting two time periods with different time lengths to alternately and circularly broadcast the real tracking area code or the virtual tracking area code, and broadcasting the tracking area code through the system message SIB1, the effect of guaranteeing the network quality of the operator while guaranteeing the public sector information acquisition can be further achieved.
In one embodiment, as shown in fig. 4, the step of broadcasting the system message SIB1 carrying the real tracking area code to the user terminal UE in the first time period and broadcasting the system message SIB1 carrying the virtual tracking area code to the user terminal UE in the second time period specifically includes the following steps:
step S402, broadcasting a system message SIB1 carrying the real tracking area code according to a first broadcasting times in the first time period;
step S404, broadcasting a system message SIB1 carrying the virtual tracking area code according to a second broadcasting times in the second time period; wherein the first broadcast times are greater than the second broadcast times.
Since guaranteeing the network quality of the operator is a main task of the public network base station, the public department collects the user information of the target user terminal UE as a secondary task, and therefore, the number of broadcasting times should be reduced when the simulation base station changed from the public network base station broadcasts the virtual tracking area code.
As an embodiment, in the first time period and in a preset unit time, the public network base station broadcasts a system message SIB1 carrying the real tracking area code for 5 to 10 times; and broadcasting a system message SIB1 carrying the virtual tracking area code for 1 to 2 times by a simulation base station changed from a public network base station in the first time period and the preset unit time.
In this embodiment, different broadcasting times are set for the real tracking area code or the virtual tracking area code, so that the effect of optimizing the network quality of the operator while guaranteeing the information acquisition of the public department can be further achieved.
In one embodiment, after the step of alternately broadcasting the real tracking area code and the virtual tracking area code to the UE according to a preset time period, the method further includes:
and in the time period of broadcasting the virtual tracking area code to the user terminal UE, if a Radio Resource Control (RRC) request sent by the target user terminal UE in an idle state is received or a paging message issued by the core network for the target user terminal UE is received, converting the virtual tracking area code into a real tracking area code.
The Radio Resource Control (RRC) request is a request for applying, controlling and scheduling resources, and the idle target user terminal (UE) needs to be connected with the core network to transmit the RRC request to the core network, so that the resource scheduling action is completed. Therefore, if the virtual tracking area code is broadcast by the emulating base station changed from the public network base station, the radio resource control RRC request of the target user terminal UE cannot be responded.
The paging message is used for notifying the target UE in the idle state through the core network, and notifying that there is data or information to be transmitted to the target UE in the idle state. After decoding the paging message content, the target user terminal UE starts a connection procedure of the wireless network.
Similarly, when the paging message issued by the core network for the target user terminal UE is received, if the virtual tracking area code is broadcast by the simulation base station changed from the public network base station at this time, the target user terminal UE cannot receive the paging message. Therefore, in the above case, the virtual tracking area code needs to be converted into the real tracking area code during the time period in which the virtual tracking area code is broadcast. Because the converted real tracking area code can be connected with the core network, a Radio Resource Control (RRC) request can be sent to the core network, and the target user terminal (UE) can receive a paging message issued by the core network.
Specifically, in a time period when the virtual tracking area code is broadcast to the user terminal UE by the emulation base station changed from the public network base station, if the emulation base station receives a radio resource control RRC request sent by the target user terminal UE in an idle state; or the simulation base station receives the paging message issued by the core network aiming at the target user terminal UE, the virtual tracking area code is converted into the real tracking area code, and the simulation base station becomes a public network base station.
Optionally, as an embodiment, during the period that the simulation base station broadcasts the virtual tracking area code, if the simulation base station receives both the radio resource control RRC request sent by the target user terminal UE in the idle state and the paging message issued by the core network for the target user terminal UE, the simulation base station implements a conversion process of converting the radio resource control RRC request and the paging message from the virtual tracking area code to the real tracking area code on the backhaul link. The converted simulation base station (namely the public network base station) can be in butt joint with the core network; if the core network transmits the paging message to the target user terminal UE at this time, the simulation base station after completing the conversion receives and identifies the paging message, and generates the paging message on the air interface, and transmits the paging message to the target user terminal UE.
In this embodiment, by converting the virtual tracking area code into the real tracking area code, the function of the core network can be provided timely when the target user terminal has a service requirement, so that the effect of improving the network quality of the operator while considering public department information acquisition can be further achieved.
In one embodiment, after the step of converting the virtual tracking area code into the real tracking area code, the method further includes:
and under the condition that the target user terminal UE is determined to be converted from the idle state to the connection state, converting the converted real tracking area code back to the virtual tracking area code.
The connection state represents that the connection between the target user terminal UE and the public network base station, and between the public network base station and the core network is established for the target user terminal UE, so that data transmission can be performed at any time.
The simulation base station receives the Radio Resource Control (RRC) request sent by the target user terminal (UE) in an idle state in the steps; or the simulation base station receives the reason that the core network transmits the paging message aiming at the target user terminal UE, and the virtual tracking area code is converted into the real tracking area code. Then, if the target UE establishes a connection with the core network, and at this time, both the RRC request and the paging message can be processed through the core network, the real tracking area code needs to be converted back into the previous virtual tracking area code.
Specifically, after the virtual tracking area code is converted into the real tracking area code, and the public network base station converts the converted real tracking area code back into the virtual tracking area code under the condition that the target user terminal UE is determined to be converted from the idle state to the connection state, so that the public department can collect user information conveniently.
In this embodiment, the real tracking area code obtained by conversion is restored to the virtual tracking area code, so that the public department is continuously guaranteed to collect the user information, and the effect of timely adopting the simulation base station to collect the user information after the target user terminal completes the service requirement can be achieved.
In one embodiment, the reject tracking area code update message sent to the target user terminal UE includes a reject code and a reject cause.
Wherein, the reject tracking area code update message sent to the target user terminal UE may be a tracking area update TAU (Tracking area update) reject message. The reject code and reject message may be "code 15: no suitable cell in tracking area).
Specifically, the emulation base station changed from the public network base station sends a TAU reject message to the target user terminal UE, where the TAU reject message carries "code 15: no suitable cell in tracking area).
In this embodiment, by returning the reject code and the reject reason, the effect of facilitating the target UE to quickly reselect back to other public network base stations or cells corresponding to the public network base stations can be achieved.
In one embodiment, before the step of obtaining the real tracking area code and the virtual tracking area code preconfigured by the public network base station, the method further includes:
and configuring public land mobile network PLMN, frequency points and physical cell identifiers PCI preset by an operator for the public network base station, and configuring a real tracking area code and a virtual tracking area code.
Wherein, PLMN is a network number established and operated for the purpose of providing land mobile communication service to the public. The frequency points refer to specific absolute frequency values. The physical cell identity PCI is used to distinguish between different cells. Before the public network base station realizes the simulation base station, the configuration information of the public network base station needs to be determined according to the parameters preset by an operator.
In this embodiment, by configuring the public land mobile network PLMN, the frequency point and the physical cell identifier PCI preset by the operator, the public network base station achieves the effect of providing high-quality network service for the user terminal UE.
As shown in fig. 5, the following describes in detail a specific implementation procedure of the implementation method of the above-mentioned simulated base station in combination with a specific embodiment, including the following steps:
Firstly, configuring public land mobile network PLMN, frequency point and physical cell identifier PCI preset by an operator for a public network base station, and configuring a real tracking area code and a virtual tracking area code.
Step two, acquiring a real tracking area code TAC and a virtual tracking area code TAC which are preconfigured by the public network base station; the real tracking area code TAC is used for interfacing with a core network; the virtual tracking area code TAC is used only on the wireless side.
Thirdly, broadcasting a system message SIB1 carrying the real tracking area code to the user terminal UE according to the first broadcasting times in a first time period T1.
Fourthly, broadcasting a system message SIB1 carrying the virtual tracking area code to the user equipment UE according to a second broadcasting frequency in a second time period T2;
and after the second time period T2 is finished, returning to execute the step of broadcasting the system message SIB1 carrying the real tracking area code to the user terminal UE in the first time period T1, wherein the first time period T1 is larger than the second time period T2, the first broadcasting times are more than the second broadcasting times, for example, the first broadcasting times are 5-10 times, and the second broadcasting times are 1-2 times.
Further, in the time period of broadcasting the virtual tracking area code to the UE, if a tracking area code update request sent by the target UE in an idle state is received, after receiving the user information sent by the target UE, a reject tracking area code update message is sent to the target UE. The reject-tracking area code update message sent to the target user terminal UE includes a reject code and a reject cause, for example, the reject-tracking area code update message carries "code 15: no suitable cell in tracking area).
Further, as shown in fig. 6, in the time period of broadcasting the virtual tracking area code to the UE, if a radio resource control RRC request sent by the target UE in an idle state is received, or a paging message issued by the core network for the target UE is received, the base station converts the virtual tracking area code broadcasted to the UE into a real tracking area code.
Further, in the case that it is determined that the target UE transitions from the idle state to the connected state, the converted real tracking area code is converted back to the virtual tracking area code.
Further, when the target UE performs cell selection and cell reselection, cell measurement may be performed based on the current beam ID or the neighbor cell in the neighbor list of the neighbor wave speed ID service sub-area.
During the broadcasting of the virtual tracking area code by the base station cell, the user terminal UE in the connected state does not read the system message in the service handover and is therefore not affected by the virtual tracking area code.
Therefore, the public network base station based on the virtual tracking area code can realize the user information acquisition capability of the simulation base station, and meanwhile, the influence on the mobile network of an operator and the user mobile experience is reduced as much as possible.
