Description

Method and device for measuring restricted network cell by terminal

The present invention relates to the field of wireless communications, and more particularly to cell measurement techniques. BACKGROUND In all cellular mobile communication technologies, when a terminal leaves a cell and enters another cell, the signal of the original cell received by the terminal is inevitably weaker, and the received signal that is entering the cell is also It will be getting stronger and stronger. Therefore, the terminal needs to handover or cell reselection to the newly entered cell. If the terminal is in the connected state, in order to maintain the communication quality of the terminal, it is necessary to switch the connection of the terminal from the original base station to the base station with a stronger incoming signal, specifically, the neighboring side of the terminal on the network side. The cell list is carried in the measurement control message and sent to the terminal. The terminal initiates measurement in each neighboring cell in the list, and reports the measurement report, and the network side performs the handover decision. If the terminal is in the idle state, the network side carries the neighbor cell list of the terminal in the system message and sends the message to the terminal. The terminal initiates measurement in each neighboring cell in the list, and performs cell reselection according to the measurement result. Request access to the reselected cell. With the development of mobile communication networks, there are restricted network cells that allow only certain specific terminals to access, wherein the restricted network cells may be private network cells, such as a home private network cell, an enterprise-level private network cell, or Other types of private network cells may also be network cells that are determined by the operator according to a certain strategy and use a specific frequency layer. Taking the private network cell of the family as an example, the private network cell of the home only allows certain terminals with the private network authority to camp or access, and at the same time, these terminals can be required to reside or access in the public network. In order to meet the above requirements, one of the more common implementation methods in the existing technical solutions is the macro cell. (ie, the public network cell) is configured as a neighboring cell in the neighboring cell list of the macro cell, and is sent to the terminal in the macro cell by using the broadcast information, and the terminal measures the private according to the neighbor cell list. The network cell tries to access. However, the inventors of the present invention have found that as the development and demand of networks continue to increase, the number of restricted network cells will also increase (e.g., the number of home private network cells increases). Therefore, if a terminal that does not have the right to access the restricted network cell is to measure and try to access the restricted network cell in which the terminal itself does not have access rights in the macro cell of the public network, the restricted network cell will reject the terminal connection. In, there will be a large number of location area update rejection processes, which not only wastes system resources, but also increases the measurement burden of the terminal. Moreover, as the number of restricted network cells continues to increase, the number of restricted network cells adjacent to the macro cell will increase (especially for larger macro cells) if all adjacent restricted network cells are to be used. The length of the neighbor cell list is increased in the neighbor cell list of the macro cell, which increases the load of the information sent by the broadcast channel.

Summary of the invention

The main technical problem to be solved by the embodiments of the present invention is to provide a method, device and system for a terminal to measure a restricted network cell, so that the efficiency of the cell measurement can be improved when the restricted network cell and the public network cell coexist. To solve the above technical problem, an embodiment of the present invention provides a method for a terminal to measure a restricted network cell, including the following steps:

Corresponding relationship between the restricted network cell to which the terminal has access and the public network cell adjacent to the restricted network cell is set in the terminal; if the current serving cell of the terminal belongs to the public network cell in the corresponding relationship, The end The terminal performs measurement on the restricted network cell corresponding to the public network cell in the corresponding relationship. The embodiment of the present invention further provides a terminal device, including: a correspondence relationship saving module, configured to save a correspondence between a restricted network cell to which the terminal has access and a public network cell adjacent to the restricted network cell; a determining module, configured to determine whether a current serving cell of the terminal belongs to a public network cell in the corresponding relationship, and a determining module, configured to determine, in the determining module, that a current serving cell of the terminal belongs to a public network in the corresponding relationship In the case of a cell, the public network cell is measured in the restricted network cell corresponding to the corresponding relationship. An embodiment of the present invention further provides a network side device, including:

a storage module, configured to store a correspondence between a restricted network cell to which the terminal device has access and a public network cell adjacent to the restricted network cell; and a notification module, configured to send, to the terminal device, the terminal A message of a correspondence between a restricted access network cell and a public network cell adjacent to the restricted network cell. Correspondingly, the embodiment of the present invention further provides a measurement system of a restricted network cell, including a terminal device and a network side device, where the network side device is configured to send, to the terminal device, a device that has the terminal device a message of the correspondence between the incoming restricted network cell and the public network cell adjacent to the restricted network cell; the terminal device, configured to save the correspondence carried in the message sent by the network side device, and determine the terminal Whether the current serving cell of the device belongs to the public network cell in the corresponding relationship, and when the determination is yes, the restricted network cell corresponding to the public network cell in the corresponding relationship is measured. the amount. Compared with the prior art, the main difference between the embodiment of the present invention and the effect thereof is: setting, in the terminal, a correspondence between the restricted network cell to which the terminal has access and the public network cell adjacent to the restricted network cell, if The current serving cell of the terminal belongs to the public network cell in the corresponding relationship, and the terminal performs measurement on the restricted network cell corresponding to the public network cell in the corresponding relationship. It can be seen that only the terminal allowed by the restricted network cell can measure the restricted network cell, avoiding the unauthorised terminal from initiating a unnecessary access procedure, which not only saves system resources, but also reduces unauthorized access. The measurement load of the terminal. Moreover, since the terminal can measure the restricted network cell with the right access by the corresponding relationship set in the terminal, the neighbor cell list broadcast by the public network cell can include the adjacent public network cell, and does not include the adjacent The network cell is limited, and therefore, the length of the neighbor cell list is reduced, so that the load of transmitting information of the broadcast channel is reduced.

detailed description

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. The embodiments of the present invention provide a main process of a method for a terminal to measure a restricted network cell. First, set a correspondence between a restricted network cell to which the terminal has access and a public network cell adjacent to the restricted network cell in the terminal. a relationship, and then, when the current serving cell of the terminal belongs to the public network cell in the corresponding relationship, the terminal performs measurement on the restricted network cell corresponding to the public network cell in the corresponding relationship, so that only the restricted network cell allows The accessed terminal can measure the restricted network cell, avoiding the unauthorised terminal from initiating a unnecessary access procedure, which not only saves system resources, but also reduces the measurement load of the unauthorized terminal. In the specific implementation, there may be multiple implementations, and various embodiments of the method of the present invention are described in detail below based on the main flow. An embodiment of the present invention relates to a method for a terminal to measure a restricted network cell, and a specific process is shown in FIG. 1 . In step 110, the network side acquires and saves the terminal information that the restricted network cell allows access. Specifically, since the network side can know which restricted network cells the terminal can access when the terminal user signs the contract, the network side can obtain the information of the terminal that the restricted network cell allows access, and save the information. The restricted network cell may be a private network cell, or may be a network cell using a specific frequency layer. Taking the private network cell A as an example, assuming that the terminal 1, the terminal 2, and the terminal 3 have the right to access the cell A, the terminal information allowed to be accessed by the cell A stored on the network side is the identifier of the terminal 1, the terminal 2, and the terminal 3. information. Then, in step 120 to step 140, after the restricted network cell is normally started, the network side carries the correspondence between the restricted network cell and the public network cell (ie, the adjacent macro cell) adjacent to the restricted network cell. In the message, the terminal is sent to the restricted network cell to allow access. Specifically, in step 120, after the restricted network cell is normally started, the network of the restricted network cell notifies the core network that the restricted network cell has started normally in the form of a start message. The terminal information allowed by the restricted network cell and the correspondence list of the restricted network cell and the neighboring macro cell may be stored in the core network. In this case, the network of the restricted network cell only needs to be notified. The core network The restricted network cell has been started normally. If the terminal information allowed by the restricted network cell and the correspondence list of the restricted network cell and the neighboring macro cell are all stored in the network of the restricted network cell, then in this case, the restricted network cell The network not only needs to notify the core network that the restricted network cell has started normally, but also needs to carry the terminal information that the restricted network cell allows access and the correspondence list of the restricted network cell and the neighboring macro cell in the message. For the above example, after the network to which the private network cell A belongs is normally started, the network to which the private network cell A belongs is notified to the core network, and the notification message may carry the terminal information that the cell A is allowed to access and the related correspondence list. (for the second case). Assume that the neighboring macro cells of the private network cell A have a macro cell B, a macro cell C, and a macro cell D, as shown in FIG. 2, then the corresponding relationship list includes the private network cell A, the macro cell B, the macro cell C, and the macro. Identification information of the cell D. Then, proceeding to step 130 and step 140, the core network performs the correspondence list of the restricted network cell and the neighboring macro cell in the message, and sends the message to the terminal that the restricted network cell allows access, and the message needs to pass the The base station of the macro cell where the terminal is located is forwarded. After the network side starts the restricted network cell, the network sends the message carrying the corresponding relationship to the terminal that is allowed to access. Therefore, after receiving the message, the terminal can learn that the restricted network cell has been activated, so that Correctly determine when Initiating measurement of the restricted network cell reduces the measurement burden of the terminal with access rights. Specifically, the core network connects the correspondence list of the restricted network cell and the neighboring macro cell to a dedicated signaling message, such as a paging message, and a Radio Resource Control (RRC) connection. The handover completion message, the trace area ("TA") update confirmation message, the cell update confirmation message, and the like, are sent to the terminal that the restricted network cell allows access. This embodiment can be flexibly implemented. For the above example, after the core network learns that the private network cell A has been started normally, the mapping list of the private network cell A and the neighboring macro cell needs to be carried in the message and sent to the terminal 1, the terminal 2, and the terminal 3. Taking the terminal 1 as an example, the terminal 1 is currently in the macro cell B. Then, the core network needs to send the message carrying the correspondence list to the base station to which the macro cell B belongs, and the base station will carry the corresponding relationship. The list of messages is forwarded to terminal 1.

If the terminal 1 is in the detached or powered-off state, the network side sends a message carrying the correspondence list to the terminal 1 when receiving the registration message sent by the terminal 1; or, setting a timer, when the timer expires The terminal 1 sends a message carrying the correspondence list. Alternatively, when the terminal 1 enters the idle state after the registration is completed, the terminal 1 transmits a message carrying the correspondence list.

If the terminal 1 is in the idle state, the message carrying the correspondence list is a paging message, and the network side sends the paging message to the terminal 1 by sending the paging message in the public network. If the terminal 1 is in the RRC connection state, the message carrying the correspondence relationship list is an RRC connection dedicated signaling message, and the network side sends the RRC connection dedicated signaling message in the public network, and sends the correspondence relationship list to the terminal 1 . Next, in step 150, after receiving the message carrying the correspondence list on the network side, the terminal saves the correspondence relationship list. When the terminal needs to measure the neighboring cell, if the current service of the terminal The serving cell belongs to the macro cell in the corresponding relationship, and while measuring the neighboring macro cell of the current serving cell, triggering measurement on the corresponding neighboring restricted network cell according to the corresponding relationship list, and when implementing, the network The side may broadcast a neighbor cell list of the macro cell in the macro cell, where the list includes macro cell information adjacent to the macro cell, and after receiving the neighbor cell list, the terminal needs to measure the neighbor cell ( When the current serving cell of the terminal belongs to the macro cell in the corresponding relationship, when the neighboring macro cell in the neighboring cell list is in the neighboring cell list, the neighboring macro cell in the current serving cell is measured. At the same time, triggering measurement on the corresponding adjacent restricted network cell according to the correspondence relationship list.

For the above example, the network side sends the corresponding relationship list after the private network cell A is normally started. Therefore, when the terminal 1 receives the correspondence relationship list, it can be known that the private network cell A has started normally. If the terminal is in the vicinity of the cell, measurements can be initiated on the cell. Since the correspondence relationship list includes the identification information of the macro cell B, the macro cell C, and the macro cell D adjacent to the private network cell A, and the terminal 1 is in the macro cell B, the terminal 1 can learn the private network. The cell A is in the vicinity of the local terminal. Therefore, when it is necessary to measure the neighboring cell, the measurement of the private network cell A can be initiated and the access is attempted. If the terminal 1 is in the idle state at this time, the terminal 1 measures the private network cell A and determines whether the reselection process needs to be performed according to the cell reselection criterion; if the terminal 1 is in the RRC connection state at this time, the network side passes The control message is measured to control the terminal to initiate measurement of the private network cell A.

Of course, after the terminal receives the message that is sent by the network side and carries the corresponding relationship list, the terminal also needs to return a response message to the network side, as shown in step 160. The flag bit can be set on the network side. When the network side receives the response message from the terminal, the flag is set to "notified terminal". Otherwise, the notification is sent again after a certain period of time to ensure that the terminal with access rights can obtain the terminal. A correspondence list to the restricted network cell and the neighboring macro cell, so that the restricted network cell can be measured and accessed. It should be noted that, in an actual application, the network side may notify the terminal of the correspondence list only when the limited network cell (such as the foregoing private network cell A) is powered on for the first time, or may be powered on each time. The terminal is notified of the correspondence list. In the former case, the flag bit may be set on the network side, and the flag bit of the successfully notified terminal is set to "notified terminal", and the terminal is not notified when the restricted network cell is powered on again next time. In the latter case, it is necessary to proceed to step 120 each time the power is turned on. It is worth mentioning that, because the network side carries the correspondence list of the restricted network cell and the neighboring macro cell in the message, and sends the message to the terminal that the restricted network cell allows access, therefore, when the network side is configured with the neighbor When the cell list is included, the restricted network cell may not be included, and the length of the neighbor cell list is reduced, so that the load of the information transmitted by the broadcast channel is reduced. It is not difficult to find that, in this embodiment, only the terminal allowed to access by the restricted network cell may measure the restricted network cell, thereby avoiding the unauthorised terminal from initiating a unnecessary access procedure, which not only saves the system. Resources, and reduce the measurement load of terminals that are not authorized. In addition, it should be noted that if the terminal has the right to access two restricted network cells, such as the private network cell A and the private network cell B, the network side starts the private network cell A and the neighboring network after the private network cell A is activated. The corresponding relationship of the public network cell is carried in the message and sent to the terminal. After the private network cell B is started, the corresponding relationship between the private network cell B and the neighboring public network cell is carried in the message and sent to the terminal, so that the embodiment is It can support the case where one terminal has the right to access multiple restricted network cells. Another embodiment of the present invention relates to a method for a terminal to measure a restricted network cell. In this embodiment, based on the foregoing implementation manner, when a correspondence between a restricted network cell and a neighboring macro cell changes, Notification process. Specifically, as shown in FIG. 3, when the correspondence between the restricted network cell and the neighboring macro cell changes, the network side carries the updated correspondence in the message, and sends the message to the restricted network cell. The terminal, so that the terminal accessing the restricted network cell can adjust the correspondence in time. The message needs to be forwarded through the base station of the macro cell where the terminal is located. After receiving the corresponding relationship, the terminal updates the previously saved correspondence and returns a response message to the network side. Still taking the terminal 1 as an example, it is assumed that the coverage of the macro cell C changes, causing the macro cell C and the private network cell A not to have the same coverage area, that is, the correspondence list of the restricted network cell and the adjacent macro cell occurs. The change information, the correspondence information list only includes the identification information of the private network cell A, the macro cell B, and the macro cell D, and the identification information of the macro cell C is no longer included. Therefore, the network side needs to carry the updated correspondence list in the message and send it to the terminal 1 so that the terminal 1 can adjust the correspondence in time. Another embodiment of the present invention relates to a method for a terminal to measure a restricted network cell. On the basis of the foregoing implementation manner, the present embodiment adds a terminal that is allowed to access in the restricted network cell, and the network side Related operations. For the example described in the above embodiments, the terminals that are allowed to access the private network cell A are the terminal 1, the terminal 2, and the terminal 3. After the private network cell A is activated, the terminal 4 also has the right to access the private network cell A. Then, the network side needs to carry the correspondence list of the private network cell A and the neighboring macro cell in the message. , sent to terminal 4. The terminal 4 sets the correspondence between the restricted network cell to which the terminal has access and the adjacent public network cell in the terminal by saving the correspondence relationship list. The specific implementation manner has been described in the embodiment shown in FIG. 1, and details are not described herein again.

Therefore, after the restricted network cell is started, if there is a new terminal that allows access to the restricted network cell, the network side needs to carry the corresponding relationship between the restricted network cell and the adjacent public network cell. In the message, the new terminal that is allowed to access the restricted network cell ensures that all authorized access terminals can measure the restricted network cell. Another embodiment of the present invention relates to a method for a terminal to measure a restricted network cell. In this embodiment, based on the foregoing implementation manner, when the terminal is prohibited from accessing the restricted network cell, the network side notifies the network. The process of deleting the related correspondence list by the terminal. For the example described in the above embodiments, the terminals that are allowed to access the private network cell A are the terminal 1, the terminal 2, and the terminal 3. 4, the terminal 2 is forbidden to access the private network cell A, then the network side needs to notify the terminal 2 to delete the saved related correspondence list. As shown in FIG. 4, the network side carries the corresponding relationship list to be deleted (including the identification information of the private network cell A, the macro cell B, the macro cell C, and the macro cell D) in the message, and sends the message to the terminal 2 to avoid the terminal 2 The private network cell A is measured to initiate a unnecessary access procedure. The message needs to be forwarded through the base station of the macro cell where the terminal 2 is located. After receiving the corresponding relationship, the terminal 2 deletes the previously stored correspondence list including the identification information of the private network cell A, the macro cell B, the macro cell C, and the macro cell D, and returns a response message to the network side, indicating that the list has been deleted. . Another embodiment of the present invention relates to a method for a terminal to measure a restricted network cell. The present embodiment is substantially the same as the embodiment shown in FIG. 1 , and the difference is that, in the embodiment shown in FIG. 1 , the network is implemented by the network. The corresponding relationship between the restricted network cell and the neighboring public network cell that the right-issued terminal has access to, and the terminal, after receiving the message carrying the corresponding relationship, saves the corresponding relationship, and sets the corresponding relationship in the terminal. In this embodiment, the terminal obtains the information of the restricted network cell and the public network cell that the terminal has access to through the interface, and directly sets the corresponding relationship in the terminal. Specifically, the terminal can be connected to a computer or other device through an interface on the terminal, and the computer or other device stores information of the restricted network cell and the public network cell that the terminal has permission to access. Then, the terminal acquires the information from the connected computer or other device, and sets the correspondence between the restricted network cell to which the terminal has access and the adjacent public network cell in the terminal. When the terminal needs to measure the neighboring cell, if the current serving cell of the terminal belongs to the neighboring public network cell in the corresponding relationship, the corresponding neighboring restricted network cell is measured according to the correspondence relationship list, and of course, Measurement is performed on neighboring public network cells of the current serving cell. One embodiment of the present invention relates to a measurement system for a restricted network cell, as shown in FIG. 5, including a network side device and a terminal device. The terminal device includes: a correspondence relationship saving module, configured to store, in the terminal, a correspondence between a restricted network cell to which the terminal device has access and a public network cell adjacent to the restricted network cell; When the neighboring cell needs to be measured, it is determined whether the current serving cell of the terminal device belongs to the public network cell in the corresponding relationship, and the measuring module is configured to determine, in the determining module, that the current serving cell of the terminal device belongs to the corresponding relationship. When the public network cell is used, the measurement is performed on the restricted network cell corresponding to the public network cell in the corresponding relationship. Of course, the measurement is also performed on the neighboring public network cell of the current serving cell. The corresponding relationship saved by the corresponding relationship holding module in the terminal device may be sent by the network side, and the terminal device includes a receiving module that receives the corresponding relationship sent by the network side; or, The terminal device sets it up by itself. Specifically, if the corresponding relationship is set by the terminal device, the terminal device further includes an obtaining module, configured to acquire information about the restricted network cell and the public network cell that the terminal has access to by using the interface; And a setting module, configured to set the correspondence according to the information acquired by the acquiring module. The corresponding relationship saved by the correspondence saving module is set by the setting module. The network side device includes: a storage module, configured to store a correspondence between each restricted network cell and a public network cell adjacent to the restricted network cell; and a notification module, configured to send the port to the terminal device A message with a correspondence between a restricted network cell to which the terminal device has access and a neighboring public network cell.

The notification module may specifically include two modules, where the startup message receiving module receives the startup message of the restricted network cell with the right access of the terminal device, and the setting module in the notification module connects the restricted network cell with the The corresponding relationship between the neighboring public network cells is carried in the message and sent to the terminal device, and the message is used to trigger setting the correspondence in the terminal device.

The message carrying the corresponding relationship may be one of the following: a paging message, an RRC connection dedicated signaling message, a handover complete message, a TA update confirmation message, a cell update confirmation message, a registration message, and the like. The restricted network cell may be a private network cell or a network cell using a specific frequency layer. The notification module may send a message carrying the correspondence to the terminal device that has the right to access the restricted network cell by using one of the following methods:

(1) If the terminal device is in a disconnected or powered-off state, when receiving the registration message sent after the terminal device is powered on, sending a message carrying the corresponding relationship to the terminal device; or, setting a timer, when the timer expires Sending a message carrying the corresponding relationship to the terminal device; or, when the terminal device enters an idle state after the registration is completed, sending a message carrying the correspondence to the terminal device.

(2) If the terminal device is in an idle state, a message carrying the correspondence is sent in the public network, and the message is a paging message.

(3) If the terminal device is in the RRC connection state, the message carrying the corresponding relationship is sent in the public network, and the message is an RRC connection dedicated signaling message.

It is worth mentioning that, after the restricted network cell is started, if the correspondence between the restricted network cell and the neighboring public network cell changes, the notification module further needs to carry the updated correspondence in the message, and send A terminal device that allows access to the restricted network cell. If in the restricted network cell After the startup, the number of the terminal devices allowed to be accessed by the restricted network cell is increased, and the notification module needs to carry the correspondence between the restricted network cell and the neighboring public network cell in the message, and send the message to the added A terminal device that allows access to the restricted network cell. In addition, if the terminal device that originally had access rights is prohibited from accessing the restricted network cell, the notification module needs to notify the terminal device to delete the previously stored correspondence relationship with the restricted network cell. It should be noted that each module in this embodiment is a logic module, and in practical applications, there may be various physical implementation manners. In the embodiment of the present invention, a correspondence between a restricted network cell to which the terminal has access and a neighboring public network cell is set in the terminal, if the current serving cell of the terminal belongs to the corresponding relationship. The public network cell, the terminal performs measurement on the neighboring restricted network cell corresponding to the public network cell in the corresponding relationship. It can be seen that only the terminal allowed by the restricted network cell can measure the restricted network cell, avoiding the unauthorised terminal from initiating a unnecessary access procedure, which not only saves system resources, but also reduces unauthorized access. The measurement load of the terminal. In addition, when the current serving cell of the terminal belongs to the macro cell in the corresponding relationship, when the neighboring macro cell of the current serving cell is measured, triggering the corresponding neighbor according to the correspondence relationship list The measurement by the restricted network cell further defines the timing of the terminal's measurement of the restricted cell, thereby further preventing the unauthorized terminal from initiating a unnecessary access procedure, further saving system resources, and further reducing the measurement load of the unauthorized terminal. . Moreover, since the terminal can measure the restricted network cell with the right access by the corresponding relationship set in the terminal, the neighbor cell list broadcast by the public network cell can include the adjacent public network cell, and does not include the adjacent The network cell is limited, and therefore, the length of the neighbor cell list is reduced, so that the load of transmitting information of the broadcast channel is reduced. After the network side is activated, the network side sends a message carrying the correspondence between the restricted network cell and the neighboring public network cell to the terminal according to the saved information of the terminal, so that after receiving the message, the terminal It can be known that the restricted network cell has been activated, so that it can correctly determine when the measurement of the restricted network cell can be initiated, and reduce the measurement burden of the terminal with the access authority. The message carrying the correspondence may be one of the following: a paging message, an RRC connection dedicated signaling message, a handover complete message, a TA update confirmation message, a cell update confirmation message. The embodiments of the present invention are made flexible.

After the restricted network cell is started, if the corresponding relationship between the restricted network cell and the neighboring public network cell changes, the updated correspondence relationship may be carried in the message by the network side, and sent to the terminal, thereby achieving The terminal can perform the effect of adjusting the correspondence in time. After the restricted network cell is started, if there is a new terminal that allows access to the restricted network cell, the corresponding relationship between the restricted network cell and the neighboring public network cell may be carried in the message through the network side, and sent The newly added terminal that allows access to the restricted network cell can achieve the effect that the authorized access terminal can measure the restricted network cell. After the restricted network cell is started, if the terminal that is allowed to access is prohibited from accessing the restricted network cell, the network side may notify the terminal to delete the corresponding correspondence between the restricted network cell and the adjacent public network cell. The relationship is such that the terminal avoids the measurement of the restricted network cell to initiate a unnecessary access procedure. While the invention has been illustrated and described with reference to the preferred embodiments embodiments The spirit and scope of the invention.
