Description

Terminal access control method, terminal and base station

Technical Field

Background

In order to meet the high-speed coverage requirement of high-speed rail users, mobile communication operators build high-speed coverage base stations along the high-speed rail and non-high-speed coverage base stations used by residents around the high-speed rail. However, as a switching relationship is configured for the two in part of provinces, residents around railways in some areas may access to high-speed coverage cells corresponding to the high-speed rail private network, occupy resources of the high-speed coverage cells, and affect the service quality of high-speed users. Meanwhile, some high-speed users may access non-high-speed coverage cells, and due to the high speed of the high-speed rails, handover is too frequent between the non-high-speed coverage cells, which may cause handover failure. In order to allow a high-speed User Equipment (UE) and a non-high-speed UE to access to a correct network, it is necessary to determine whether each UE is a high-speed UE or a non-high-speed UE, i.e., a UE speed. The mobility detection result supported by the current Long Term Evolution (LTE) can only reflect the relative speed of User Equipment (UE), and the difference between a high-speed coverage cell and a non-high-speed coverage cell is large, so that the UE cannot be directly applied, and therefore, in a high-speed application scene of a mobile communication network, it is difficult to avoid the situation that the non-high-speed UE along a railway is accessed into the high-speed coverage cell and the situation that the high-speed UE is accessed into the non-high-speed coverage cell.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings.

The embodiment of the invention provides a terminal access control method, a terminal and a base station, which solve the problem that non-high-speed UE (user equipment) along a railway is difficult to access a high-speed coverage cell and high-speed UE is difficult to access the non-high-speed coverage cell in a high-speed railway application scene of a mobile communication network.

First embodiment

As shown in fig. 1, an embodiment of the present invention provides a terminal access control method, which is applied to a base station, and includes:

step 101: the method comprises the steps of obtaining a speed identification of a terminal, wherein the speed identification is used for indicating the moving state of the terminal and comprises a high-speed identification and a non-high-speed identification.

Here, after the terminal without the speed identifier goes into the RRC-CONNECTED state, the base station obtains the speed identifier of the terminal, so that the base station determines the type of the cell accessed by the terminal, such as a high-speed coverage cell or a non-high-speed coverage cell, according to the speed identifier.

Specifically, the base station may obtain a speed identifier of the terminal according to a residence time of the terminal in N high-speed coverage cells, where N is a positive integer; or

The step of the base station obtaining the speed identifier of the terminal according to the stay time of the terminal in the N high-speed coverage cells may further include: measuring the stay time of the terminal in the N high-speed coverage cells; and if the stay time of the terminal in the N high-speed coverage cells is less than or equal to a first preset stay threshold, determining that the speed identifier of the terminal is a high-speed identifier.

Further, the base station measures the stay time of the terminal in the N high-speed coverage cells by setting a timer for each high-speed coverage cell.

In the embodiment of the invention, a timer is added in each high-speed coverage cell to monitor the time length of the UE staying in the cell (when the high-speed coverage cell establishes connection with a certain UE, the timer is added for the UE); for each high-speed coverage cell, setting the first preset stay threshold value for the timer according to the moving speed of the high-speed train and the coverage characteristics (such as shape, area and the like) of the cell; when the high-speed coverage cell establishes connection with a certain UE, a corresponding timer is (re) started; when the connection between the high-speed coverage cell and a certain UE is released, the timer is stopped and the value of the timer is stored; for the same UE, if the value of the timer in the N accessed cells does not exceed a first preset stay threshold value set for the UE, the speed identifier of the UE is judged to be a high-speed identifier, otherwise, the speed identifier of the UE is judged to be a non-high-speed identifier. After judging the speed identification of the UE, the UE side and the network side store the speed identification of the UE so that the base station can subsequently determine whether the terminal is accessed to a high-speed coverage cell or a non-high-speed coverage cell.

Step 102: and controlling the terminal to access a high-speed coverage cell or a non-high-speed coverage cell according to the speed identifier of the terminal.

Specifically, if the speed identifier of the terminal is a high-speed identifier, the terminal is controlled to access a high-speed coverage cell, and if the speed identifier of the terminal is a non-high-speed identifier, the terminal is controlled to access a non-high-speed coverage cell, so that the terminal is accessed to a cell matched with the speed identifier of the terminal, and the non-high-speed terminal is prevented from using resources of the high-speed coverage cell.

In the terminal access control method of the embodiment of the invention, a base station acquires a speed identifier of a terminal, wherein the speed identifier is used for indicating the moving state of the terminal and comprises a high-speed identifier and a non-high-speed identifier; and controlling the terminal to access a high-speed coverage cell or a non-high-speed coverage cell according to the speed identifier of the terminal. In the embodiment of the invention, the base station determines the cell (high-speed coverage cell or non-high-speed coverage cell) accessed by the terminal by obtaining the speed identifier of the terminal, so that the non-high-speed terminal is prevented from using the resource of the high-speed coverage cell, the resource of the high-speed coverage network is ensured to provide better service for the high-speed terminal, and the use experience of a high-speed user is improved.

Second embodiment

As shown in fig. 2, an embodiment of the present invention further provides a terminal access control method, which is applied to a base station, and includes:

step 201, obtaining a speed identifier of a terminal, wherein the speed identifier is used for indicating the moving state of the terminal, and the speed identifier comprises a high-speed identifier and a non-high-speed identifier.

This step is the same as step 101 described above and will not be described here.

And 202, if the cell switching condition is met, controlling the terminal to access a high-speed coverage cell or a non-high-speed coverage cell matched with the speed identifier according to the speed identifier of the terminal, wherein the high-speed identifier is matched with the high-speed coverage cell, and the non-high-speed identifier is matched with the non-high-speed coverage cell.

Specifically, if the cell switching condition is met, the terminal is controlled to access a high-speed coverage cell or a non-high-speed coverage cell matched with the speed identifier through an X2 or S1 interface according to the speed identifier of the terminal.

Further, if the cell switching condition is satisfied, after the step of controlling the terminal to access the high-speed coverage cell or the non-high-speed coverage cell matched with the speed identifier according to the speed identifier of the terminal, the terminal access control method further includes:

Here, after a terminal accesses a cell matching a speed identity of the terminal, the speed identity of the terminal is transmitted to a base station corresponding to the cell accessed by the terminal, so that the base station controls the terminal to always switch to the cell matching the speed identity of the terminal in subsequent handover.

Step 203: if the cell switching condition is not met and the type of the cell currently accessed by the terminal is not matched with the speed identifier of the terminal, after the current service of the terminal is finished, the connection with the terminal is released, priority indication information is added in a corresponding Radio Resource Control (RRC) connection release message, so that the terminal is redirected to a high-speed coverage cell or a non-high-speed coverage cell matched with the speed identifier according to the priority indication information, wherein the priority indication information is used for reducing the access priority of the cell with the same cell type as the cell currently accessed by the terminal.

Here, when the determined UE speed identifier is not consistent with the current access cell type, if the handover condition is not satisfied, the current Connection is released (considering the user experience, the Connection may be released after the current service is ended), and an indication is added in a corresponding Connection Release message (RRC Connection Release): the method includes the steps of reducing the UE-specific priority of a current connection type cell, enabling the UE to be accessed to a cell with the speed identification consistent with the speed identification of the UE when cell reselection is carried out after current connection is released, and increasing priority indication information for reducing the priority of a high-speed coverage cell or a non-high-speed coverage cell in connection release information when the connection release information is sent to a terminal by an Evolved Universal Terrestrial Radio Access Network (E-UTRAN).

The following describes in detail an implementation process of accessing a high-speed coverage cell or a non-high-speed coverage cell matched with the speed identifier through an X2 or S1 interface in the embodiment of the present invention with reference to the drawings.

The implementation mode is as follows: and accessing a high-speed coverage cell or a non-high-speed coverage cell matched with the speed identifier through an X2 interface.

As shown in fig. 3, assuming that a cell switching condition is satisfied, a speed identifier of a terminal is not matched with a type of a cell to which the terminal is currently accessed, and a base station obtains the speed identifier of the terminal by receiving the speed identifier sent by the terminal, the implementation process specifically includes:

step 301: the source base station sends measurement control to the terminal.

Step 302: the terminal determines a speed identifier, and adds the speed identifier to a measurement report message to be reported to the source base station.

Step 303: and the source base station judges that the speed identifier of the terminal is not matched with the type of the cell covered by the source base station and meets the cell switching condition, and then sends a switching request containing the speed identifier to a target base station, wherein the type of the cell covered by the target base station is matched with the speed identifier of the terminal.

Specifically, whether a cell handover condition is met is determined according to an existing standard protocol, and the type of the cell covered by the target base station is matched with the speed identifier, for example, if the speed identifier is a high-speed identifier, the cell covered by the target base station is a high-speed covered cell, and if the speed identifier is a non-high-speed identifier, the cell covered by the target base station is a non-high-speed covered cell.

Step 304: and the target base station stores the speed identification of the terminal and performs access control on the terminal according to the speed identification.

Step 305: and the target base station sends a switching request confirmation message to the source base station.

Step 306: and the source base station sends the RRC connection reconfiguration message containing the mobile control information to the terminal.

In the first implementation manner, after the UE speed identifier is determined, the UE speed identifier is added to a Measurement report Measurement Reports message and reported to the source base station. And when the judged UE speed identifier is not consistent with the type of the current access cell, if the switching condition is met, switching the UE back to the cell consistent with the speed identifier, and transmitting the UE speed identifier to the target base station by the source base station in the switching process.

The following describes the UE speed identity delivery and handover process based on the X2 interface after the terminal accesses the appropriate cell with reference to fig. 4.

As shown in fig. 4, the handover procedure includes:

step 401: the source base station sends measurement control to the terminal.

Step 402: and the terminal sends a measurement report message to the source base station according to the measurement control.

Step 403: and the source base station determines a target base station matched with the speed identifier of the terminal according to the stored speed identifier of the terminal, and sends a switching request containing the speed identifier to the target base station if the switching condition is met.

Step 404: and the target base station stores the speed identification of the terminal and performs access control on the terminal according to the speed identification.

Step 405: and the target base station sends a switching request confirmation message to the source base station.

Step 406: and the source base station sends the RRC connection reconfiguration message containing the mobile control information to the terminal.

After the UE accesses the cell matched with the speed identifier, the handover decision method is the same as the first implementation manner, and the UE speed identifier is used to ensure that the UE is handed over to the appropriate cell, that is, the high-speed UE does not leave the high-speed coverage cell, and the non-high-speed UE does not leave the non-high-speed coverage cell. Meanwhile, if an X2 interface exists between the source base station and the target base station, the source base station transmits the UE speed identifier to the target base station through a Handover Request message in the Handover process, so that the target base station can confirm the UE speed identifier again in access control.

The implementation mode two is as follows: and accessing a high-speed coverage cell or a non-high-speed coverage cell matched with the speed identifier through an S1 interface.

And if the X2 interface does not exist between the source base station and the target base station, the source base station transmits the UE speed identification to the target base station through the S1 interface in the switching process. As shown in fig. 5, the method comprises the following steps:

step 501: the source base station sends measurement control to the terminal.

Step 502: the terminal determines a speed identifier, and adds the speed identifier to a measurement report message to be reported to the source base station.

Step 503: and the source base station judges that the speed identifier of the terminal is not matched with the type of the cell covered by the source base station and meets the cell switching condition, and then sends a switching request containing the speed identifier to a Mobility Management Entity (MME), wherein the type of the cell covered by the target base station is matched with the speed identifier of the terminal.

Step 504: and the MME sends the switching request containing the speed identifier to a target base station.

Step 505: and the target base station stores the speed identification of the terminal and performs access control on the terminal according to the speed identification.

Step 506: and the target base station sends a switching request confirmation message to the MME.

Step 507: the MME sends a handover command to the source base station.

Step 508: and the source base station sends the RRC connection reconfiguration message containing the mobile control information to the terminal.

The following describes the UE speed identity delivery and handover procedure based on the S1 interface after the terminal accesses the appropriate cell, with reference to fig. 6.

As shown in fig. 6, if there is no X2 interface between the source base station and the target base station, the source base station transmits the UE speed id to the target base station through the S1 interface during the handover procedure.

Step 601: the source base station sends measurement control to the terminal.

Step 602: and the terminal sends a measurement report message to the source base station according to the measurement control.

Step 603: and the source base station determines the speed identifier of the terminal and a target base station matched with the speed identifier of the terminal according to the stored speed identifier of the terminal, and sends a switching request containing the speed identifier to a Mobility Management Entity (MME) if the cell switching condition is met.

Step 604: and the MME sends the switching request containing the speed identifier to a target base station.

Step 605: and the target base station stores the speed identification of the terminal and performs access control on the terminal according to the speed identification.

Step 606: and the target base station sends a switching request confirmation message to the MME.

Step 607: the MME sends a handover command to the source base station.

Step 608: and the source base station sends the RRC connection reconfiguration message containing the mobile control information to the terminal.

Here, if there is no X2 interface between the source base station and the target base station, the source base station transfers the UE speed id to the target base station through the S1 interface during the handover procedure.

In the embodiment of the invention, for non-high-speed UE in a high-speed coverage cell, if a switching condition is met, the non-high-speed UE is switched to the non-high-speed coverage cell, and a source base station transmits a UE speed identifier to a target base station; if the switching condition is not met, after the service is finished, releasing the connection, redirecting the UE to a non-high-speed coverage cell (carrier), and reporting the speed identifier of the UE to a newly accessed base station by the UE; for high-speed UE in a non-high-speed coverage cell, if a switching condition is met, switching the high-speed UE to the high-speed coverage cell, and transmitting the UE identity identifier to a target base station by a source base station; if the switching condition is not satisfied, after the service is finished, the connection is released, the UE is redirected to a high-speed coverage cell (carrier), and the UE reports the speed identification of the UE to the newly accessed base station. In the subsequent switching, the source base station makes a switching decision according to the UE speed identification on the basis of the measurement report and the RRM information so as to prevent the high-speed UE from accessing the non-high-speed coverage cell or the non-high-speed UE from accessing the high-speed coverage cell again, and the source base station continues to transmit the UE speed identification to the target base station.

As shown in fig. 7, an embodiment of the present invention further provides a terminal access control method, which is applied to a terminal, and includes:

step 701: and determining a speed identifier of the terminal, wherein the speed identifier is used for indicating the moving state of the terminal and comprises a high-speed identifier and a non-high-speed identifier.

Here, the terminal may obtain a first number of times that the terminal is switched to the high-speed coverage cell and a second number of times that the terminal is switched to the non-high-speed coverage cell according to a cell type of a target cell that is recorded in advance and to which the terminal is switched within a predetermined time period; according to a preset first weight of a first time and a preset second weight of a second time, carrying out weighted summation on the first time and the second time to obtain a pseudo switching time; and if the pseudo switching times are larger than a preset switching threshold value, determining that the speed identifier of the terminal is a high-speed identifier, otherwise, determining that the speed identifier of the terminal is a non-high-speed identifier.

Specifically, in a certain time T, the UE counts the switching times of the target base station, which is a high-speed coverage base station and a non-high-speed coverage base station respectively, when the UE performs cell switching; according to the difference of the high-speed coverage cell and the non-high-speed coverage cell in the aspects of signal intensity distribution, shape and the like, different weight values are allocated to the high-speed coverage cell and the non-high-speed coverage cell; adding the switching times of the two types with weights to obtain a 'pseudo switching time'; for the 'pseudo switching times', setting a threshold value (preset switching threshold value) aiming at the high mobility grade; and if the pseudo switching times are larger than a preset switching threshold value, determining that the speed identifier of the terminal is a high-speed identifier, otherwise, determining that the speed identifier of the terminal is a non-high-speed identifier.

Or, the terminal may also count the stay time of the terminal in the N high-speed coverage cells according to a timer set in the terminal; and if the stay time of the terminal in the N high-speed coverage cells is less than or equal to a second preset stay threshold, determining that the speed identifier of the terminal is a high-speed identifier.

Specifically, a timer is added to each UE to monitor the duration of staying in the high-speed coverage cell; for each high-speed coverage cell, setting a threshold value for the timer according to the moving speed of the high-speed train and the coverage characteristics (shape, area and the like) of the cell, and sending the threshold value to the UE accessed to the high-speed coverage cell through an RRC Connection Reconfiguration (RRC Connection Reconfiguration) message or an RRC Connection Setup (RRC Connection Setup) message; when the UE establishes connection with a certain high-speed coverage cell, the timer is (re) started; when the connection between the UE and a certain high-speed coverage cell is released, the timer is stopped and the value of the timer is stored; for the same UE, if the value of the timer in the N high-speed coverage cells accessed by the UE does not exceed the corresponding threshold value, the speed identifier of the UE is judged to be a high-speed identifier; otherwise, the speed identifier of the UE is judged to be a non-high speed identifier.

Step 702: and sending the speed identifier to a base station, so that the base station controls the terminal to access a high-speed coverage cell or a non-high-speed coverage cell according to the speed identifier.

Specifically, the speed identifier is sent to the base station through a measurement report.

Further, after the step of sending the speed identifier to the base station, the method for controlling access of the terminal further includes:

acquiring an RRC connection release message which is sent by a base station and contains priority indication information, wherein the RRC connection release message is sent when the base station does not meet cell switching conditions and the type of a cell currently accessed by the terminal is not matched with a speed identifier of the terminal, and the priority indication information is used for reducing the access priority of a cell which has the same cell type as the cell currently accessed by the terminal; and redirecting to a high-speed coverage cell or a non-high-speed coverage cell matched with the speed identifier according to the priority indication information.

Here, when the UE speed identifier determined by the base station is not consistent with the current access cell type, if the handover condition is not satisfied, the current Connection is released (considering the user experience, the Connection may be released after the current service is ended), and an indication is added in a corresponding Connection Release message (RRC Connection Release): the UE-specific priority of the current connection type cell is reduced, so that after the current connection is released, the UE accesses to the cell with the same speed identifier as the current connection when performing cell reselection, for example, when an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) sends a connection release message to a terminal, priority indication information for releasing the priority of a high-speed coverage cell or a non-high-speed coverage cell is added to the connection release message.

The terminal access control method of the embodiment of the invention determines the speed identification of the terminal, wherein the speed identification is used for indicating the moving state of the terminal and comprises a high-speed identification and a non-high-speed identification; and sending the speed identifier to a base station, so that the base station controls the terminal to access a high-speed coverage cell or a non-high-speed coverage cell according to the speed identifier, thereby preventing the non-high-speed terminal from using the resources of the high-speed coverage cell, ensuring that the resources of the high-speed coverage network can provide better service for the high-speed terminal, and further improving the use experience of a high-speed user.
