Description

Tracking area identification determining method, device and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a tracking area identifier determining method, apparatus, and storage medium.

Background

The tracking area (TRACKING AREA, TA) is a new concept set up by the long term evolution (Long Term Evolution, LTE) system for location management of terminals (UEs). The tracking area Code (TRACKING AREA Code, TAC) is an encoding of the tracking area within the public land mobile network (Public LandMobile Network, PLMN) for location management of the UE, unique within the PLMN. In a satellite mobile communication system, a network needs to be able to grasp the approximate location of a terminal in order to be able to find the terminal through a paging procedure. In order to realize this function, the satellite mobile communication system needs to reasonably plan the TA and execute corresponding processing procedures on the following beams, which relate to system message broadcasting, registration and paging.

In the related art, along with the movement, the UE needs to continuously read the system message to obtain whether the TA currently located is the same as the TA currently stored by the UE, and if the TA currently located is different from the TA currently stored by the UE, the UE needs to perform a registration process to inform the network of the new TA where the UE is located, so that the network can know which TA the UE is currently located in real time. In order to find the called terminal more accurately, the detailed location of the terminal is known as much as possible, that is, the TA is divided as small as possible, and the TAC broadcasted in the system message is required to be small, and the small TAC means that the base station broadcasts the TAC more frequently when the satellite flies across the ground, which increases the overhead of the base station.

Detailed Description

In the conventional terrestrial wireless communication system, the UE does not require the capability of the global navigation satellite system (Global Navigation SATELLITE SYSTEM, GNSS) and does not have such a capability, so that the UE cannot determine whether a new area is reached by itself but only by TAC broadcasted through the network. In the related art, along with the movement, the UE needs to continuously read the system message to obtain whether the TA currently located is the same as the TA currently stored by the UE, and if the TA currently located is different from the TA currently stored by the UE, the UE needs to perform a registration process to inform the network of the new TA where the UE is located, so that the network can know which TA the UE is currently located in real time. In order to find the called terminal more accurately, the detailed location of the terminal is known as much as possible, that is, the TA is divided as small as possible, and the TAC broadcasted in the system message is required to be small, and the small TAC means that the base station broadcasts the TAC more frequently when the satellite flies across the ground, which increases the overhead of the base station.

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Fig. 1 is a schematic diagram of a tracking area identifier determining process according to the related art provided by the present application, as shown in fig. 1, the process of the method is as follows:

1. The network broadcasts a corresponding tracking area identification code (TRACKING AREA IDENTITY, TAI) or TAIs in the system message according to the size of the ground tracking area plan; and the UE reads the system information during the period of covering the current area by the beam jump to acquire the current tracking area.

2. The UE judges whether the TAI stored by the UE is contained in the broadcast TAI or TAIs, if the TAI is not contained in the broadcast TAI, the TAI is crossed to different TAs, a traditional Non-Access Stratum (NAS) registration process is initiated, and the TAI where the UE is currently located is informed to a core network; the core network sets a tracking area identification code List (TAI List) for the UE according to a certain rule.

3. When paging is required, the TAI List is sent to the relevant base station (gNB) in a paging message of NGAP protocol.

4. The base station calculates which wave bit or wave bits of which wave beam or beams of which satellite or satellites at the current moment will cover the tracking area according to ephemeris information and the like, and sends paging messages on the wave bits.

Fig. 2 is one of flow diagrams of a tracking area identifier determining method according to an embodiment of the present application, and as shown in fig. 2, an embodiment of the present application provides a tracking area identifier determining method, where an execution body may be a UE. The method comprises the following steps:

step 201, determining the current location information of the UE.

Specifically, the UE determines its own location information, where the location information may be the longitude and latitude of the UE, or may be the distance between the UE and a certain reference point. And then, according to the geographical position of the current tracking area, judging which TA is located by itself to obtain the tracking area identification code TAI.

For example, the UE determines its longitude and latitude using GNSS.

As another example, the UE determines its distance from a certain reference point using GNSS.

Step 102, determining a first tracking area identifier based on the current position information of the UE.

Specifically, the UE uses its own positioning capability to determine which TA is located according to the current geographic location of the UE, so as to obtain the TAI. And then the UE judges whether the current geographic position crosses the previous TAI, if so, a NAS registration process is initiated, and the current TAI of the UE is informed to the core network through a registration request message of the process. The core network allocates a round of TAIs around it, based on certain rules depending on the algorithm implementation, e.g. typically centered on the reported TAIs, sets a TAI List for the UE, and then sends it to the UE via a registration accept message (Registration Accept).

Further, when paging is required, the TAI List parameter is sent to the relevant gNB in a paging message of NG interface Protocol (Protocol for NGINTERFACE, NGAP). The base station calculates which wave bit or wave bits of which wave beam or beams of which satellite or satellites at the current moment will cover the tracking area according to ephemeris information and the like, and sends paging messages on the wave bits.

The embodiment of the application provides a tracking area identification determining method, which binds TA and geographic position, and then transfers the task of calculating TAC by a base station to the UE by utilizing the self positioning capability of the UE, so that the base station side does not need to broadcast the TAC in a system message, the processing process is simplified, and the expenditure of the base station is reduced.

Specifically, in the "fixed TA" mode, the TA and the geographic location area fixed on the ground are bound, and by adopting this TA planning, on the one hand, which TA is can be deduced from the geographic location, and on the other hand, it is also possible to determine where the approximate geographic location area is by looking back at the TA. The geographic location area is absolute, the TAC is a logic value, and if the TA planning scheme between the two is known in advance by the network side and the terminal side (for example, a fixed mapping relation table exists, or can be calculated through an algorithm, etc.), the UE can obtain the corresponding TAI by using its own location information.

Further, the UE needs to determine the geographic area to which the UE currently belongs before obtaining the corresponding TAI by using its own location information.

For example, whether the longitude and latitude of the user are within the area divided according to the longitude and latitude can be determined to determine the geographical area to which the user belongs.

For another example, the geographic area to which the self belongs may be determined by determining whether the distance from the self to the reference point is less than a prescribed distance.

Specifically, in the system design implementation, the base station side and the terminal side are made aware of a specific TA plan, and the TA plan is the same. The binding rules between the geographic area and the TAI may be preconfigured, where preconfiguration refers to human settings and is uniformly defined by the specifications of the regulatory authorities.

The embodiment of the application provides a tracking area identification determining method, which binds TA and geographic position, and then transfers the task of calculating TAC by a base station to UE by utilizing the self positioning capability of the UE. Along with the movement of the satellite, the base station does not need to carry out a TAC identification process, a calculation process and a system message broadcasting process, so that the processing process is simplified, and the processing pressure of the base station is reduced.

In some embodiments, the method further comprises:

Specifically, in the system design implementation, the base station side and the terminal side are made aware of a specific TA plan, and the TA plan is the same. Binding rules between the geographic area and the TAI may be configured to the terminal by the network device. The network side can obtain the TA planning scheme or update the TA planning scheme according to the change or algorithm of the existing data, and send the TA planning scheme or update the TA planning scheme to the UE.

A polygonal region centered on the reference point.

Specifically, the network binds the TA and the geographic position, and the binding method has various common ways that the earth surface is divided into a plurality of grids according to longitude and latitude, each grid corresponds to a certain geographic area, the boundary of each grid is described by longitude and latitude, and each grid is identified by a globally unique TAC. And the TA planning schemes of the reference point and the distance, and the like, and both the network side and the terminal side are required to know the planning and designing methods of the reference point and the distance, so that the UE can derive the reference point and the distance by itself by utilizing the GNSS capability of the UE, and the broadcasting of the system information of the base station is avoided.

For example, a hexagonal area surrounded by a line with a distance d ₁ from the reference point is associated with a TA, and if the distance d ₁ from the reference point by the UE is smaller, the UE is determined to be in the TA.

For another example, a triangle area surrounded by a line with a distance d ₁ from the reference point is associated with a TA, and if the distance d ₁ from the reference point by the UE is smaller, the UE is determined to be in the TA.

The embodiment of the application provides a tracking area identification determining method, which binds TA and geographic position, and then uses the self positioning capability of UE to transfer the task of a base station to calculate TAC to the UE, and because the base station is not required to broadcast the TAC in a system message, how the TAC is planned is not limited by the size of the system message and the capability of the base station, the TA can be divided into small areas, the accuracy of a position area reported by the UE is high, accurate paging can be realized, and the paging cost is small.

In some embodiments, the method further comprises:

Specifically, the UE determines whether the current geographic location has crossed the previous TAI, and if the current geographic location TAI is different from the previous TAI, initiates a NAS registration procedure, and informs the core network of the current TAI of the UE through a registration request message of the procedure. After the core network knows the TA of the terminal from the registration process, when the network side needs to page the terminal, the base station can calculate which beams of which satellites cover the area at the current moment through ephemeris, and paging messages are sent on the relevant beams, so that accurate paging is realized.

The embodiment of the application provides a tracking area identification determining method, wherein UE (user equipment) utilizes the positioning capability of the UE, calculates in which TA the current geographic position is according to a TA planning scheme, calculates TAC (traffic control) and starts a registration process if the TAC crosses a tracking area, and does not need to judge by reading the TAC in a system message in a traditional mode.

In some embodiments, the method further comprises:

Specifically, after knowing the TA where the terminal is located in the core network from the registration process, the core network sets a TAI List for the UE according to a certain rule (depending on the algorithm implementation), and then sends the TAI List to the UE through a registration acceptance message.

For example, the reported TAI is centered, and a circle of TAI is distributed around the TAI to form TAIList. The network device sends the TAI List to the UE.

The embodiment of the application provides a tracking area identification determining method, which binds TA and geographic position, then uses the self positioning capability of UE to transfer the task of calculating TAC by a base station to the UE, and makes the UE not need to report TAI frequently through a TAI List, thereby simplifying the processing process and reducing the expenditure of the base station.

In some embodiments, the method further comprises:

Specifically, the UE determines whether the current geographic location has crossed the previous TAI List, if the TAI of the current geographic location is not in the stored TAI List, then initiates a NAS registration procedure, and informs the core network of the TAI of the current UE through a registration request message of the procedure. After the core network acquires the TA of the terminal from the registration process, the core network sets a new TAI List for the UE according to a certain rule, and then sends the new TAI List to the UE through a registration acceptance message. When the network side needs to page the terminal, the base station can calculate which beams of which satellites at the current moment cover the new TAI List area through ephemeris, and paging messages are sent on the relevant beams, so that accurate paging is realized.

The embodiment of the application provides a tracking area identification determining method, which binds TA and geographic position, and then transfers the task of calculating TAC by a base station to the UE by utilizing the self positioning capability of the UE, so that the base station side does not need to broadcast the TAC in a system message, and the UE does not need to report TAI frequently through a TAI List, thereby simplifying the processing process and reducing the expenditure of the base station.

Distance information to the reference point.

Specifically, the UE uses its own positioning capability to determine which TA is located according to the current geographic location of the UE, so as to obtain the TAI. The required location information will also differ according to the binding rules of TA and geographical location.

For example, in the case where the binding rule is divided into a plurality of grids using longitude and latitude, and each grid corresponds to a certain geographical area, the UE needs to determine own longitude and latitude information.

For another example, in case the binding rule uses a reference point and a distance, the UE needs to determine the distance between itself and the reference point.

The method in the above embodiment is further described below with several specific examples.

Example one:

fig. 3 is a schematic diagram of a tracking area identifier determining process according to an embodiment of the present application, and as shown in fig. 3, the process of the method is as follows:

1. the UE calculates the TAI itself based on its GNSS capabilities.

2. The UE judges whether the current geographic position crosses the previous TAI, if so, a NAS registration process is initiated, and the current TAI of the UE is informed to the core network through a registration request message of the process. The core network sets a TAI List for the UE according to a certain rule (depending on the algorithm implementation, e.g. generally centered on the reported TAI, around which a circle of TAIs is allocated), and then sends the UE a registration accept message.

3. When paging is needed, the TAI List parameter is sent to the relevant gNB in the paging message of the NGAP protocol.

Example two:

The network binds the TA and the geographic position according to rules, and the binding method has various common methods, namely dividing the earth surface into a plurality of grids according to longitude and latitude, wherein each grid corresponds to a certain geographic area, the boundary of each grid is described by longitude and latitude, and each grid is identified by a globally unique TAC.

Fig. 4 is one of the planning designs for TA and geographic location area binding provided by the embodiment of the present application, and as shown in fig. 4, the tracking area identification determination procedure is as follows:

1. Each tracking area identifies a geographic area, commonly referred to as latitude and longitude. The UE uses its own GNSS capability to automatically judge which TA is located according to the current geographical position (longitude and latitude), and registers when the trigger condition is satisfied. As shown in fig. 4, for example, tai=3 tracking area ranges: left boundary x1, right boundary x2, upper boundary y2, lower boundary y3. Assuming that there is a terminal coordinate (x, y) therein, as the terminal moves, it can be determined that it enters the tracking area of tai=4 when x3> x > x2 and y2> y > y3, thereby starting the registration process.

2. After the network learns the TA (tai=4, for example) where the terminal is located from the registration process, the network has left and right boundaries of x2 to x3 and upper and lower boundaries of y2 to y3, respectively. When the network side needs to page the terminal, the ephemeris is used for calculating which beams of which satellites cover the area at the current moment, and paging messages are sent on the relevant beams, so that accurate paging is realized.

Example three:

The present embodiment adopts a reference point-distance TA planning scheme. Under the scheme, fixed reference points are fixedly arranged on the ground, and the distance between the fixed reference points and the ground is d ₁ (the left and right distances from the reference points), and the range of d ₂ (the upper and lower distances from the reference points) belongs to a tracking area (square when d ₁＝d₂). The coordinates of the fixed reference points, the distances d ₁ and d ₂ are known to both the information network side and the terminal side and can therefore be processed by the method according to the application.

Fig. 5 is a second plan design of TA and geographic location area binding provided by an embodiment of the present application, and as shown in fig. 5, the tracking area identification determination procedure is as follows:

1. Each tracking area identifies a geographic area. The UE uses its own GNSS capability to automatically judge which TA is located according to the current geographical position (longitude and latitude), and registers when the trigger condition is satisfied. As shown in fig. 5, for example, tai=3 tracking area ranges: coordinates (x 1, y 2) are the center reference points of the tracking areas of tai=3, the tracking areas of tai=3 range from x1-d ₁ to x1+d ₁, and the up-down ranges from y2-d ₂ to y2+d ₂. Assuming that there is a terminal coordinate (x, y) therein, as the terminal moves, it can be determined that it enters the tracking area of tai=4 when x2+d ₁>x>x1+d₁ and y2-d ₂>y>y2+d₂, thereby starting the registration process.

2. After the network learns the TA (tai=4 for example) where the terminal is located from the registration process, the left and right boundaries are x2-d ₁、x2+d₁, and the upper and lower boundaries are y2+d ₂ and y2-d ₂, respectively. When the network side needs to page the terminal, the ephemeris is used for calculating which beams of which satellites cover the area at the current moment, and paging messages are sent on the relevant beams, so that accurate paging is realized.

According to the tracking area identification determining method, the tracking area identification determining device and the storage medium, the TA and the geographic position are bound, and the task of calculating the TAC by the base station is transferred to the UE by utilizing the positioning capability of the UE, so that the base station side does not need to broadcast the TAC in a system message, and the expenditure of the base station is reduced.
