Description

Data connection distribution method and device using Beidou positioning and short message system

Technical Field

The present application relates to the field of communications, and in particular, to a data connection allocation method and apparatus using a beidou positioning and short message system.

Background

Currently, communication systems are typically only capable of providing communication services to terminals located within the coverage area of a signal. For example, when the terminal is located within the coverage area of a cell of a certain base station, the terminal may search for a corresponding frequency point to receive a system message broadcasted by the cell, thereby obtaining a communication service through the cell accessing the network.

However, this access mode is relatively limited, and once the terminal is located outside the signal coverage area, the terminal cannot obtain the communication service, resulting in service interruption.

Disclosure of Invention

The embodiment of the application provides a data connection distribution method and a data connection distribution device by using a Beidou positioning and short message system, which are used for realizing that a terminal can still access a network when the terminal is positioned outside a signal coverage area.

In order to achieve the above purpose, the application adopts the following technical scheme:

in a first aspect, a data connection allocation method using a beidou positioning and short message system is provided, and the method includes: in the process that the terminal accesses the network through the Beidou satellite, the terminal receives a Beidou short request message from a data management network element through the Beidou satellite, wherein the Beidou short request message carries positioning configuration information protected by integrity; the terminal performs integrity check on the positioning configuration information protected by the integrity; under the condition that the integrity check is passed, the terminal performs positioning according to the positioning configuration information to obtain the position information of the terminal, wherein the position information is used for triggering a data management network element to distribute data connection for the terminal, and the data connection is used for the terminal to communicate with a network; and the terminal sends the position information to the data management network element through the Beidou satellite.

Based on the method of the first aspect, it can be known that, in the case that the terminal is not located within the signal coverage area of the cell, the terminal may still select to access the network through the beidou satellite, for example, the terminal may receive the positioning configuration information protected by integrity from the data management network element through the beidou satellite, and perform positioning if the integrity check passes, so as to feed back the location information of the terminal to the data management network element, so that the data management network element may trigger to allocate appropriate data connection to the terminal according to the location information of the terminal, so as to ensure that the terminal may ultimately access the network.

In a possible design, the terminal sends the location information to the data management network element through the beidou satellite, including: the terminal sends a Beidou short response message carrying integrity-protected position information to a data management network element through a Beidou satellite, wherein the Beidou short response message is used for indicating that the terminal has received positioning configuration information, and the integrity-protected position information contains the position information so as to prevent that a network cannot distribute proper data connection for the terminal due to the fact that the position information is tampered, and finally the terminal still cannot access the network.

To facilitate understanding of the embodiments of the present application, a communication system suitable for use in the embodiments of the present application will be described in detail with reference to the communication system shown in fig. 2. Fig. 2 is a schematic diagram of a communication system to which the data connection allocation method using the beidou positioning and short message system according to the embodiment of the present application is applicable.

As shown in fig. 2, the communication system may be adapted for the above 5GS, including: a terminal and a data management network element. The terminal may be a terminal mentioned in the above 5GS and the data management network element may be a UDM mentioned in the above 5 GS. The specific interaction between the terminal and the data management network element may refer to the following method embodiments, which are not described herein.

The following describes the interaction flow between each network element/device in the above communication system in detail through an embodiment of the method in conjunction with fig. 3. The data connection allocation method using the Beidou positioning and short message system provided by the embodiment of the application can be applied to the communication system.

Specifically, as shown in fig. 3, the flow of the method is as follows:

s301, in the process that the terminal accesses the network through the Beidou satellite, the data management network element sends a Beidou short request message to the terminal through the Beidou satellite, and correspondingly, the terminal receives the Beidou short request message from the data management network element through the Beidou satellite.

The Beidou short request message carries positioning configuration information protected by integrity, and specifically can comprise the positioning configuration information and hash finish value of the positioning configuration information.

The positioning configuration information may be configuration parameters required by the terminal to perform positioning, such as a time point of performing positioning, a time-frequency position of a reference signal used for positioning, and the like, and is not limited.

The hashed value of the location configuration information may be a hashed value obtained by the data management network element requesting an authentication network element (AUSF) to perform integrity protection on the location configuration information. For example, the authentication network element may perform hash operation on the random number and the positioning configuration information by using the root key of the terminal, to obtain a hash-guaranteed value of the positioning configuration information.

Optionally, the Beidou short request message can also carry the random number.

S302, the terminal performs integrity check on the integrity-protected positioning configuration information.

The terminal can use the root key of the local storage terminal to carry out hash operation on the received positioning configuration information and the random number to obtain the hash check value of the positioning configuration information. At this time, the terminal may compare whether the hash-completion value of the positioning configuration information is consistent with the hash-check value of the positioning configuration information, that is, perform integrity check on the positioning configuration information that is integrity-protected. If the hash finish value of the positioning configuration information is consistent with the hash check value of the positioning configuration information, the integrity check is passed, otherwise, the integrity check fails.

S303, under the condition that the integrity check is passed, the terminal performs positioning according to the positioning configuration information, and the position information of the terminal is obtained.

The location information may be the location coordinates of the terminal, specifically, the longitude and latitude coordinates of the terminal, or may also be coordinates that can be identified by the network, such as XX units, XX streets, and the like. The location information may be used for the data management network element to trigger the allocation of data connections for the terminal. The data connection is used for the terminal to communicate with the network, and the type of data connection may include a near-end relay connection or a far-end relay connection. The near-end relay connection refers to relay connection of a terminal accessing a network through an access point at the edge of a cell; the remote relay connection refers to relay connection of the terminal through the Beidou satellite access network.

S304, the terminal sends the position information to the data management network element through the Beidou satellite, and the data management network element receives the position information from the terminal through the Beidou satellite correspondingly.

The terminal can send a Beidou short response message carrying the integrity protected position information to the data management network element through a Beidou satellite. The Beidou short response message can be used for indicating that the terminal has received positioning configuration information, the integrity-protected position information comprises position information and the hash value of the position information is ensured, so that the situation that the network cannot distribute proper data connection for the terminal due to the fact that the position information is tampered is prevented, and finally the terminal still cannot access the network is caused.

Mode 1:

the terminal may determine the hash value of the integrity protection (i.e., the hash-complete value of the location information) based on the received random number, the acknowledgement ACK information, and the location information. For example, the terminal may perform hash operation on the random number, acknowledgement ACK information, and location information using a locally stored root key of the terminal to obtain an integrity protected hash value. The confirmation information may be used to indicate that the terminal has received the positioning configuration information, where the integrity-protected location information may include location information and a hash value, and the integrity-protected confirmation information includes the confirmation information and the hash value. And then, the terminal can carry the confirmation information, the position information and the hash value into the Beidou short response message. That is, the terminal may multiplex the feedback ACK information timing, and combine the ACK information and the configuration information to perform integrity protection, so that feedback overhead may be reduced.

Mode 2:

the terminal may determine the first hash value of the integrity protection (i.e., the hash-full value of the location information) based on the received random number and the location information. For example, the terminal may perform a hash operation on the random number and the location information by using a locally stored root key of the terminal, to obtain a first hash value of integrity protection. At this time, the integrity-protected location information includes location information and a first hash value. Meanwhile, the terminal can also determine a second hash value of the integrity protection according to the random number and the confirmation information. For example, the terminal may perform a hash operation on the random number and the acknowledgement information by using the locally stored root key of the terminal, to obtain the integrity-protected second hash value. At this time, the second hash value and the acknowledgement information are the acknowledgement information that is integrity protected. And then, the terminal can carry the position information protected by the integrity and the confirmation information protected by the integrity to the Beidou short response message. That is, the terminal may multiplex the feedback ACK information timing, and perform integrity protection on the ACK information and the configuration information separately, so that the flexibility of feedback may be improved, and certain forward compatibility may be achieved, for example, in a case where the old data management network element does not support performing the security check on the received positioning information, the old data management network element may still perform performing the security check on the received ACK information, so as to avoid complete failure of the flow.

Mode 3:

after the terminal obtains the first hash value and the second hash value by using the method of mode 2, the terminal may determine a third hash value (i.e., a hash-guaranteed value of the location information) according to the first hash value and the second hash value. For example, the terminal may use the locally stored root key of the terminal to continue to perform hash operation on the first hash value and the second hash value to obtain a third hash value. At this time, the integrity-protected location information includes location information and a third hash value, and the integrity-protected acknowledgement information includes acknowledgement information and a third hash value. And then, the terminal can carry the confirmation information, the position information and the third hash value into the Beidou short response message.

And S305, the data management network element triggers the terminal to distribute data connection according to the position information.

The data management network element may perform an integrity check on the received location information. For example, the data management network element may generate the hash check value of the location information in a similar manner to the terminal, and then compare whether the hash check value of the location information is consistent with the hash check value of the location information.

If the location information indicates that a cell exists near the terminal under the condition that the security check is passed, the data management network element determines that the type of the data connection is near-end relay connection, wherein the near-end relay connection refers to relay connection of the terminal accessing the network through an access point at the edge of the cell; or if the position information indicates that a cell does not exist near the terminal, the data management network element determines that the data connection is far-end relay connection, and the far-end relay connection refers to relay connection of the terminal through a Beidou satellite access network; the data management network element sends the type of the data connection to the access and mobility management network element to trigger the access and mobility management network element to distribute the corresponding type of the data connection for the terminal, so as to ensure that the terminal can still access the network finally.

In summary, under the condition that the terminal is not located within the signal coverage area of the cell, the terminal can still select to access the network through the Beidou satellite, for example, the terminal can receive the positioning configuration information which is protected by the integrity and comes from the data management network element through the Beidou satellite, and perform positioning under the condition that the integrity check is passed, so that the position information of the terminal is fed back to the data management network element, and the data management network element can trigger to allocate proper data connection for the terminal according to the position information of the terminal, so as to ensure that the terminal can finally access the network.

In combination with the foregoing embodiment, in one possible design, the terminal may further send capability information protected by integrity to the data management network element in the case that the integrity check passes. Wherein the integrity-protected capability information is used to indicate the type of data connection supported by the terminal. For example, the types of data connections supported by the terminal may include a near-end relay connection and/or a far-end relay connection. In this way, failure of the terminal to access the network due to the terminal not supporting some data connections can be avoided.

The data connection allocation method using the Beidou positioning and short message system provided by the embodiment of the application is described in detail above with reference to fig. 3. The following describes in detail a communication device for executing the method provided by the embodiment of the present application with reference to fig. 4 to 5.

Fig. 4 is a schematic structural diagram of a communication device according to an embodiment of the present application. Illustratively, as shown in fig. 4, the communication device 400 includes: a transceiver module 401 and a processing module 402. For ease of illustration, fig. 4 shows only the main components of the communication device.
