Description

The present invention relates to the field of communication, and more particularly to base station equipment, wireless terminal equipment and communication systems.

With the constant development of wireless communication, the application of Machine Type Communication (MTC) is also becoming more and more important. Primarily includes article tracking / tracking, environmental / climate monitoring, remote medical care, etc. Since the application scene of MTC is very wide, the research subjects on MTC are increasing accordingly. For example, how to realize energy saving and how to realize cost reduction. Research is being conducted on whether it can be done and how it can improve network coverage. However, one of the key assumptions about these studies is that they build on and enhance traditional LTE systems.
Achieve the research goals of these issues.

As research on these issues continues to progress, both of these issues face one and the same issue: how to obtain the system information (SI, System Information) broadcast by the network. Is it? System information is essential information for a user device (UE, User Equipment) (despite being idle or connected) to work normally. The system information is notified by the base station in a specific cell, and all UEs in this cell need to obtain such system information. The UE can perform processes such as cell selection / reelection, cell switching (handover), and service start only after obtaining such system information.

It should be noted that the above-mentioned introduction of the background technology is for the purpose of clearly and completely explaining the technical proposal of the present invention and making it easy for those skilled in the art to understand it. These proposals are described in the background art portion of the present invention and should not be construed as well known to those skilled in the art.

However, the inventor of the conventional LTE system due to some peculiarities of MTC UE, for example, system information is not updated in a timely manner, downlink reception capability is limited, and channel conditions are not good. We have found that adopting the system information acquisition mechanism causes many problems.

For example, the user device cannot obtain system information in a timely manner. If the length of the change cycle for updating system information is smaller than the paging cycle of the MTC UE, the user device can receive the update instruction contained in the paging information in a timely manner within one change cycle. Or, the acquisition of unnecessary system information will appear. Many MTC UEs are slower and less sensitive to delay, so MTC UEs are more slow than traditional UEs.
The frequency of system information updates is rather low.

The embodiments of the present invention provide a system information acquisition method, apparatus and system, thereby enhancing the conventional system information update mechanism so that the MTC UE can acquire the latest system information in a timely manner. Not only can it reduce the power consumption of the MTC UE without acquiring unnecessary system information.

Although the specification and the drawings disclose a specific embodiment of the present invention, it indicates only a partial embodiment in which the principle of the present invention can be adopted, and it should be understood that the present invention is described in this invention. It is not limited to the described embodiments, that is, the invention includes all modifications, modifications and alternatives within the appended claims.

In the examples of the present invention, MTC UE will be described below as an example. The system information acquisition method and the change cycle configuration method in the embodiment of the present invention are not limited to the MTC UE, and can be applied to the embodiment of the present invention as long as there are at least two types of user devices. ..

The system information is broadcast by the base station in a specific cell, and control of the user device in the idle state and the connected state can be realized. Over time, the network can update system information based on the current network state. In the conventional LTE system, the modification period (MP, Modification Period) is adopted.
It is possible to update the system information.

FIG. 1 is a diagram showing the update of system information in the conventional standard. As can be seen from Fig. 1, if there is a change in the system information (for example, other than ETWS (Earthquake and Tsunami Warning System), CMAS (Commercial Mobile Alert Service), and EAB (Extended Access Barring) parameters), the network side will change. The update instruction (for example, by paging information) is transmitted within the cycle n, and the updated system information is transmitted within the change cycle n + 1.

When the UE receives the update instruction from the network side, the update instruction (for example, change cycle n)
It is necessary to obtain new system information as soon as one change cycle (for example, change cycle n + 1) next to is started. The modification period T _MP is determined by two parameters, which are the default paging cycle T _paging (default paging cycle) and the modification period coefficient MP _coe (modification period coefficient), respectively, and these two parameters are notified by the base station. ..

T _MP = MP _coe * T _paging (1)
As shown in the above equation (1), the change cycle value can be obtained from the paging cycle value and the change cycle coefficient value. The boundary of the change cycle is represented by a system frame number (SFN, System Frame Number) value that satisfies a certain condition, that is, SFN mod m = 0. Of these, m is the number of wireless frames included _{in the T MP.}

An embodiment of the present invention provides a system information acquisition method, and the embodiment of the present invention will be described below from the base station side. FIG. 2 is a flowchart of a system information acquisition method according to an embodiment of the present invention, and as shown in FIG. 2, the acquisition method includes the following steps.

Step 201: The base station sets up at least two system information update directives, the at least two directives corresponding to at least two user devices, respectively;
Step 202: The base station sends an indicator to the user device, which obtains system information based on its own change cycle.

In this embodiment, the base station side can set an indicator for instructing the update of system information for at least two UEs in the same cell. For convenience, the conventional UE and the MTC UE will be described as examples below, but the present invention is not limited thereto. For example, it may be another type of UE, or it may be three or more types of UEs, and these UEs can be indicated using three or more types of directives, and the actual situation. It is also possible to determine a specific implementation method according to the above.

In this embodiment, the at least two directives may be included in the paging information, respectively. By independently setting at least two indicators for updating system information, the base station can achieve the purpose of notifying at least two UEs (conventional UE and MTC UE), respectively. Of these, different change cycles can be configured for at least two UEs, and for example, different change cycles may be set in advance for at least two UEs, and the change cycles are configured by the base station. However, the present invention is not limited to this.

For example, for the conventional UE and the MTC UE, different change cycles can be configured, that is, for the conventional UE, the change cycle PA can be configured, and for the MTC UE, the change cycle PB can be configured. be able to. Among them, PA may be smaller than PB.

In this embodiment, the user apparatus can update the system information based on its own change cycle after receiving the indicator transmitted by the base station.

FIG. 3 is a diagram showing an example of a system information acquisition method according to an embodiment of the present invention. As shown in FIG. 3, the change cycle of the conventional UE (UE A) is PA, and the change cycle of MTC UE (UE B) is PB. UE
After receiving the indicator in the change cycle n, if the indicator is an indicator for the UE A, UE A updates the system information in the change cycle n + 1. As shown in FIG. 3, after receiving the indicator in the change cycle m, if the indicator is an indicator for the UE B, the UE B
Updates the system information in the change cycle m + 1.

As can be seen from the above embodiment, the base station independently sets the directives for updating the system information, so that the MTC UE can not only acquire the latest system information in a timely manner, but also. It is also possible to reduce the power consumption of MT UE without acquiring unnecessary system information.

FIG. 4 is a diagram showing another method of acquiring system information according to an embodiment of the present invention. As shown in FIG. 4, the acquisition method includes the following steps.

Step 401: The base station configures a change cycle for at least two user devices, respectively;
Step 402: The base station sets up directives to direct at least two system information updates, the at least two directives corresponding to at least two user devices;
Step 403: The base station sends an indicator to the user device, which causes the user device to
Get system information based on your own change cycle.

In this embodiment, the new change period value may be determined by the base station and may be transmitted by notifying in the system information; or transmitted by transmitting the relevant parameters in dedicated signaling. Also good, for example, RRC (Radio Resource Control)
It can be transmitted by signaling or MAC (Medium Access Control) signaling.

In step 401, the conventional standard change cycle value may be adopted for one of the user devices (conventional UE); the following processing may be performed for the other user device (MTC UE).

In one embodiment, the change cycle value can be transmitted to the user device. For example, the base station may directly generate one new change period value and transmit the change period value to the user device.

Alternatively, in another embodiment, by transmitting the paging cycle value to the user device, the user device can obtain the change cycle value based on the paging cycle value and the existing change cycle coefficient. For example, if the base station ^{generates only one new default paging period T *} _paging and reuses the existing change period factor, the corresponding change period value T ^* _MP is T ^* _MP = MP _coe *. It can be expressed as T ^* _paging.

Alternatively, in another embodiment, by transmitting the paging cycle value and the change cycle coefficient to the user device, the user device may obtain the change cycle value based on the paging cycle value and the change cycle coefficient. For example, if the base station ^{produces one new default paging period T *} _paging and one new change period factor MP ^* _coe , the corresponding change period value T ^* _MP is T ^* _MP = MP ^* _coe * T ^* _paging. Can be expressed as.

Also, the boundary of the new change cycle may be determined by the conventional method, that is, SFN mod m ^* = 0, of which m ^* is the number of radio frames included ^{in T *} _MP.

After configuring the change cycle for at least two user devices in step 401, steps 402 and 403 may be executed to acquire system information, and the specific contents are described in steps 201 and 403 described above. 202 can be referred to.

In this embodiment, the system information may be partially updated or may be completely updated. Some system information may be updated independently for different UEs in the same cell and may need to be updated synchronously.

In one embodiment, sending an indicator to a user device in step 403 specifically sends an indicator at different times for two or more user devices, thereby causing two or more user devices. May include updating part or all of the system information at the same time based on their change cycle.

First, a simple classification of system information may be performed, for example, conventional UE and MTC UE.
System information that requires simultaneous update of is called Class A system information, for example, TDD (Time Division Duplex) configuration in Master Information Block (MIB, Master Information Block), System Information Block 1 (SIB1, System Information Block 1), and Bandwidth indicator, frequency information in system information block 2 (SIB2), etc. Other system information that is not included in class A system information may be referred to as class B system information.

Based on this, the new system information update mechanism defines two system information change directives, one is traditionally used for the UE and the other is used for the new UE. You may. If there is a change in the class B system information, the base station can independently set two directives for updating the system information, thereby achieving the purpose of notifying the conventional UE and the new UE, respectively. If there is a change in the Class A system information, the base station needs to ensure that the conventional UE and the new UE update the system information at the same time.

FIG. 5 is a diagram showing another example of the system information acquisition method according to the embodiment of the present invention. As shown in FIG. 5, the change cycle of the conventional UE (UE A) is PA, and the change cycle of MTC UE (UE B) is PB.
Conventional UE and MTC In order for UE to acquire class A information synchronously, an indicator for UE A is transmitted at a change cycle of n + 8, and an indicator for UE B is transmitted at a change cycle of m + 1. As a result, UE A and UE B can update the system information at the same time (at the start of the change cycle n + 9 and the change cycle m + 2).

In this embodiment, the method further comprises transmitting some or all of the system information to the user device by dedicated signaling.

For example, after the introduction of a new change cycle, a UE that uses the new change cycle may affect the communication of other UEs in the current network because it does not get new system information when trying to start the uplink service. There is. Therefore, some system information can be transmitted to the UE by a dedicated signaling method, and may be carried by RRC signaling of SRB1 (Signaling Radio Bearer) and SRB2, for example.

Note that the method of transmitting a part or all of the system information to the user device by dedicated signaling is not limited to the case of using at least two directives, or is not limited to the case of using at least two change cycles. It can also be applied when using one directive or one change cycle.

As can be seen from the above embodiment, the base station independently sets the directives for updating system information for the user equipment, for example, the MTC UE acquires the latest system information in a timely manner. Not only can this be done, but the power consumption of the MTC UE can also be reduced without retrieving unnecessary system information.

Step 602: The user device establishes that the indicator corresponds to the user device;
Step 603: The user device obtains system information based on the change cycle of the user device.

In this embodiment, the base station can set an indicator for updating system information for at least two user devices, respectively. One user device (eg MTC UE)
After receiving the indicator transmitted by the base station side, determines whether the indicator is for the user device, that is, corresponds to a change cycle for updating the system information of the user device. Determine if you want to. When it is determined that the change cycle for updating the system information of the user device is supported, the user device acquires the system information based on its own change cycle.

Step 701: The user device receives the change cycle configuration information transmitted by the base station, of which the base station configures the change cycle for at least two user devices;
Step 702: The user apparatus obtains a change cycle for updating system information based on the configuration information.

Among them, the configuration information of the change cycle may include the change cycle value, and the user device can directly obtain the change cycle value. Alternatively, the configuration information of the change cycle may include a paging cycle value, in which case the user apparatus can obtain the change cycle value based on the paging cycle value and the existing change cycle coefficient. Alternatively, the configuration information of the change cycle may include a paging cycle value and a change cycle coefficient, in which case the user device can obtain the change cycle value based on the paging cycle value and the change cycle coefficient.

Step 703: The user device receives an indicator to instruct the system information update;
Step 704: The user device determines if the directive is for the user device, and if determined to be for the user device, performs step 705;
Step 705: The user device obtains system information based on the change cycle of the user device.

As can be seen from the above embodiment, for example, the MTC UE acquires the latest system information in a timely manner by independently setting the directives for updating the system information for the user equipment. Not only can this be done, but the power consumption of the MTC UE can also be reduced without retrieving unnecessary system information.

To obtain the change cycle value based on the paging cycle value and the existing change cycle coefficient; or, by transmitting the paging cycle value and the change cycle coefficient to the user device, the user device can obtain the paging cycle value and the change. It includes getting the change period value to be obtained based on the period coefficient.
