Description

Network connection control method and device Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a network connection control method and device.

Background technique

With the rapid development of wireless communication technologies, the Long Term Evolution (LTE) network has been rapidly deployed and popularized, and the number of wireless users has increased dramatically. The emerging mobile terminal services represented by high-definition multimedia streaming services have also emerged rapidly.

As more and more applications are installed on the mobile terminal, the application device (UE) can establish a connection with the application server by establishing a Radio Resource Control (RRC) connection with the LTE network. And the data exchange, and the process of establishing the RRC connection, that is, the process that the UE changes from the idle (IDLE) state to the CONNECTED state, generates a large amount of signaling, including: RRC, radio link control (Radio Link Control) , RLC), medium access control (MAC), and physical downlink control channel (PDCCH) signaling. Moreover, the application server of each application actively pushes information to the UE through the LTE network more frequently, which may result in a more frequent paging process, thereby generating more paging signaling. Therefore, frequent RRC connection setup and paging procedures can cause severe signaling load on the LTE network.

In order to reduce the frequency of RRC connection establishment and thus reduce the signaling required for RRC connection establishment, the LTE network may configure a long discontinuous reception (DRX) period to keep the UE in a connected state for as long as possible.

In the Third Generation Partnership Project (3GPP) protocol, the UE under DRX stops monitoring the PDCCH for a period of time. There are two types:

I. IDLE DRX is a discontinuous reception when the UE is in the IDLE state. Since there is no RRC connection and the user's proprietary resources when in the IDLE state, this is mainly to monitor the call channel and the broadcast channel, as long as the definition is fixed. The DRX cycle can achieve the purpose of discontinuous reception. If the UE wants to listen to the user data channel, it needs to enter the connection state from the IDLE state first.

Second, the active DRX (ACTIVE DRX), that is, the DRX in the RRC-CONNECTED state of the UE. In this state, the UE does not need to constantly monitor the downlink data and related processing for a period of time, and there is still an RRC connection. The DRX with the aforementioned configuration may be ACTIVE DRX.

The LTE network is configured with a longer DRX period for the UE, which causes the UE to be in a connected state for a long time. According to the LTE protocol, the UE in the connected state needs to perform cell handover when moving between cells, which may result in signaling requirements for a large number of cell handovers. In particular, the interaction of UE context information. Therefore, the scheme for reducing signaling in the above scheme is not ideal, and the load of communication network signaling is still heavy.

detailed description

The present invention will be further described in detail with reference to the accompanying drawings, in which . All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

According to the Third Generation Partnership Project (3GPP), [TS 36.300], User Equipment (UE) has two RRC states:

First, RRC_IDLE, this state contains the following characteristics:

1. Public Land Mobile Network (PLMN) selection;

2. DRX configured by the non-access stratum (NonAccess Stadium, NAS);

3. System information of the broadcast;

4. Paging;

5. Mobility based on cell reselection;

6. Assign a unique identifier (Identity, ID) in the Tracking Area (TA) to the UE;

7. The eNB side does not store the RRC context of the UE;

8. (Device-to-Device, D2D) communication transmission and reception (a technology that allows UEs to directly communicate by multiplexing cell resources under the control of the system);

9, D2D discovery and monitoring.

Second, RRC_CONNECTED, this state contains the following characteristics:

1. The UE has an Evolved Universal Terrestrial Radio Access Network RRC (E-UTRAN-RRC) connection.

2. The UE has a context in the E-UTRAN;

3. E-UTRAN knows which cell the UE belongs to;

4. The network can receive and send data to and from the UE;

5. Mobility of network control;

6. Pro-cell measurement;

7. D2D communication transmission and reception;

8, D2D discovery and monitoring;

9. From the PDCP, RLC, and MAC layers;

10. The UE can receive and send data to and from the network.

11. The UE detects control signaling for the shared data channel.

In the LTE system, the paging function can notify the UE in the IDLE state to establish a connection with the network and become a CONNECTED state to receive data. To implement this function, the Mobility Management Entity (MME) of the LTE core network needs to send paging (Paging) signaling to all base stations in the Tracking Area (TA) where the UE is located, and then these base stations pass through the air interface. The RRC message broadcasts the paging signal to find the UE in an idle state. After receiving the paging message sent by the base station, the UE starts to establish a connection with the network and enters the connection state.

In order to reduce the amount of system signaling generated by the UE from the IDLE state to the CONNECTED state and improve the speed of service establishment and data transmission and reception, the UE can be kept in the CONNECTED Status, even if the UE has no data to send and receive for a period of time, it remains in the CONNECTED state. At the same time, in order to avoid the unnecessary handover process (the UE performs cell reselection) in the CONNECTED state of the service without the service, a large amount of handover signaling is generated, so that the UE without the service and in the CONNECTED state can follow the IDLE during the mobile process. The state of the cell measurement and reselection mechanism for mobility management does not trigger the handover process. Since the handover procedure is not triggered, the MME and the base station do not know which cell the UE is in. Therefore, the MME needs to send paging signaling to all base stations in the tracking area where the UE that is always in the CONNECTED state and has no service.

The present invention proposes a method for reducing paging signaling generation for a non-serving UE that is always in the CONNECTED state. After the UE's service transmission is completed for a period of time, the UE remains in the CONNECTED state, but refers to the IDLE state cell reselection mechanism when moving (does not trigger the handover procedure). After completing the cell reselection, the UE sends an uplink signaling to notify the current cell of its own existence, and the uplink signaling may be physical layer signaling or higher layer signaling. After receiving the uplink signaling sent by the UE, the LTE Evolved Base Station (eNB) informs the MME of the serving cell where the UE is located through the S1 interface, so that the MME can accurately send the paging signaling subsequently. In addition, the LTE eNB may perform one uplink signaling transmission after the UE is reselected N times, so that the UE can prevent the UE from transmitting uplink signaling frequently during the mobile process. The numerical value of N can comprehensively consider the moving speed of the UE, the overhead generated by the reporting of the UE, and the reduction of the paging signaling caused by the improved location accuracy of the UE, thereby making a compromise, and the N can be determined and informed by the MME. The LTE eNB connected thereto, the LTE eNB then configures the value to the UE by using broadcast RRC signaling or unicast RRC signaling.

When the MME needs to page the UE, the MME may send the paging signaling only to the LTE eNB that last reported the location information and the LTE eNB around the N-circle, without sending to the LTE eNB in the entire tracking area (TA). Paging signaling; since only the LTE eNB receiving the MME paging signaling will send paging signaling to the UE to serve the paging UE, the paging signaling overhead can be greatly saved.

As a more specific example, please refer to the system structure diagram shown in FIG. 1. In FIG. 1, 19 base stations are sequentially numbered as base station #1 to base station #19; it is assumed that base station #1 is the last reported UE. The base station of the location information also shows the base station to which the paging signaling of the MME needs to be sent when N=1 and N=2, and when N=1, the paging signaling of the MME needs to transmit the base station #1~ Base station #7.

FIG. 1 is an example, based on the schematic diagram of the system structure shown in FIG. 1 above, and the specific process is as follows:

Step 1: At time T1, the UE in the CONNECTED state performs data communication with the base station #1.

Step 2: At time T2, the UE in the CONNECTED state completes the data transmission and reception, and the CONNECTED state continues for a certain period of time, and the UE performs mobility management according to the cell measurement and reselection mechanism of the IDLE state during the mobile process.

In this step, the MME can consider the signaling load of the current network, and configure the UE to perform uplink signaling after performing two cell reselection to inform the base station of its own location, that is, N=2.

Step 3: At time T3, the UE moves to the boundary between base station #1 and base station #2, and reselects the serving cell as base station #2 after performing cell measurement. After the cell reselection is completed, UE#1 has just performed a cell reselection at this time, and has not reached 2 times, so it does not send an uplink signal to the base station #2 to inform the MME of its existence.

Step 4: At time T4, there is data on the network side that needs to be sent to the UE. Therefore, the MME needs to send paging signaling to find the UE. Since the UE last communicates with the base station #1, and N=2, the MME only needs to go to the base station# 1 and its surrounding base stations, that is, base station #2 to base station #19, transmit paging signaling without having to send paging signaling to all base stations in the TA.

Step 5: After receiving the paging message sent by the base station #2, the UE starts to receive data through the base station #2.

In the above technical solution, the MME and the LTE eNB can dynamically configure the reporting accuracy of the location information of the UE that is always in the connected state and has no service, that is, N.

After the N-th cell reselection is completed, the non-serving UE sends an uplink signaling to inform the current cell of its own existence, that is, the location information. The MME value needs to send the paging signaling to the LTE eNB that last reported the location information and the LTE eNB of the surrounding N-circle, and only the LTE eNB that receives the MME paging signaling will continue to deliver the paging signaling. The generation of paging signaling is greatly reduced.

Based on the above description, an embodiment of the present invention provides a paging control method for a mobile terminal, as shown in FIG. 2, including:

201: The mobile terminal in the connected state keeps the connection state after performing data transmission and reception, and performs cell The measurement then performs cell reselection according to the result of the cell measurement, and does not initiate cell handover;

After the mobile terminal completes the data transmission and reception, it refers to the state in which the mobile terminal performs data transmission and reception and data transmission and reception after the mobile terminal enters the connection state. In this state, there is no service data transmission and reception requirement, and the connection state is still in this state, and the mobile terminal may move in this state. The cell handover may be caused, and the cell handover may not be initiated. The cell handover may be performed by referring to the mobile terminal in the idle state, and the cell measurement and reselection may be performed in the idle state mode, so that the cell handover process will not be triggered, so the reselection process is not The signaling overhead required for cell handover will be added. Cell measurement and reselection in an idle state is an improvement based on compatibility with the 3GPP protocol. The measurement of the cell may be specifically performed on the signal quality of the cell, and is used to determine which cell is more suitable for access. This is not specifically described in the 3GPP protocol.

The embodiment of the present invention further provides a specific implementation manner of maintaining the connection state, as follows: the mobile terminal in the connected state keeps the connection state after the data is transmitted and received, and the mobile terminal in the connected state keeps monitoring the physical downlink control channel after completing the data transmission and reception. Or, the period of discontinuous reception of the activity is extended, so that the mobile terminal in the connected state keeps the connection state after the data is transmitted and received.

202: After the cell reselection is completed, the mobile terminal sends the current location information of the mobile terminal to the management device of the access device corresponding to the cell where the mobile terminal is currently located.

In this embodiment, the mobile terminal informs the management device of the location information of the mobile terminal, so when the management device needs to find the mobile terminal, it does not need to send paging signaling to all base stations in the tracking area, and does not need to track the area. All base stations broadcast paging signaling to find the mobile terminal, so paging signaling can be reduced; in addition, the mobile terminal can remain in the connected state for a long time, and can be less switched between the idle state and the connected state. The signaling overhead required for the state switching is reduced. In addition, when the mobile terminal performs cell measurement and reselection in an idle state during the process of maintaining the connection state, the cell handover process will not be triggered, so no cell handover will be added. The required signaling overhead. In summary, the above technical solution can reduce the load of communication network signaling.

As an optional embodiment, the location information may be reported by the mobile terminal itself, or only one uplink signaling may be sent to trigger the location information of the mobile terminal that is sent by the access device corresponding to the cell where the mobile terminal is currently located, and the location information may be The identifier of the cell may also be any identifier that can be identified by the management device and the location of the mobile terminal, and is not limited by the embodiment of the present invention. As a preferred technical solution, the mobile terminal may only send the information. The uplink signaling is as follows: The sending the current location information of the mobile terminal to the management device of the access device corresponding to the cell where the mobile terminal is currently located includes:

Sending, to the access device corresponding to the cell where the mobile terminal is currently located, the uplink signaling, where the uplink signaling is used to trigger the access device corresponding to the cell currently located by the mobile terminal to send the cell where the mobile terminal is currently located to the management device. .

As a more specific example, the foregoing uplink signaling includes:

Physical layer signaling, Medium Access Control (MAC) layer signaling, or Radio Resource Control layer signaling. It can be understood that if other signaling is used to communicate with the access device during the measurement and access process in the idle mode when the mobile terminal is in the connected state, other layer signaling may also be used, which is not used by the embodiment of the present invention. Uniqueness is limited.

In the implementation of the present invention, the mobile terminal may report the location information every time the cell reselection, or may set the number of reselection times by the network side, so as to conveniently control the accuracy of reporting the location information of the mobile terminal without the service data, as follows: Before the management device of the access device corresponding to the cell currently located by the terminal sends the current location information of the mobile terminal, the method further includes:

The cell reselection is counted. If the cell reselection times reaches the threshold, the management device that performs the foregoing access device corresponding to the cell currently located by the mobile terminal is configured to send the current location information of the mobile terminal.

In this embodiment, the threshold value may be preset, or may be set by the management device according to a predetermined rule, or may be adjusted, as follows: Before counting cell reselection, the foregoing method further includes:

Receiving configuration information sent by the management device, and the threshold value is specified in the configuration information.

As a more specific example, the embodiment of the present invention may be applied to an LTE system, where the access device is a long-term evolution type base station, and the management device is a mobility management entity.

Another embodiment of the present invention provides a paging control method for a mobile terminal, as shown in FIG. 3, including:

301: The management device of the access device receives the location information of the mobile terminal. The location information is maintained by the mobile terminal in the connected state after the data is sent and received, and the cell measurement is performed, and then the cell reselection is performed according to the result of the cell measurement, and the cell is not initiated. Switching, and transmitting, by the calibration access device, after the cell reselection is completed; the calibration access device is currently the mobile terminal An access device corresponding to the cell;

302: The foregoing management device determines that the mobile terminal needs to be paged, and sends paging signaling to the calibration access device.

In this embodiment, the mobile terminal informs the management device of the location information of the mobile terminal, so when the management device needs to find the mobile terminal, it does not need to send paging signaling to all base stations in the tracking area, and does not need to track the area. All base stations broadcast paging signaling to find the mobile terminal, so paging signaling can be reduced; in addition, the mobile terminal can remain in the connected state for a long time, and can be less switched between the idle state and the connected state. The signaling overhead required for the state switching is reduced. In addition, when the mobile terminal performs cell measurement and reselection in an idle state during the process of maintaining the connection state, the cell handover process will not be triggered, so no cell handover will be added. The required signaling overhead. In summary, the above technical solution can reduce the load of communication network signaling.

In the implementation of the present invention, the mobile terminal may report the location information every time the cell reselects, or may set the number of reselection times by the network side, so as to conveniently control the accuracy of reporting the location information of the mobile terminal without the service data, as follows: Before receiving the location information of the mobile terminal, the foregoing method further includes:

The foregoing sending the paging signaling to the calibration access device includes:

Paging signaling is sent to an access device that is within the above set threshold from the above-mentioned calibration access device.

Optionally, in the embodiment of the present invention, the threshold value may be arbitrarily set, or may be calculated by considering a plurality of factors, as follows: Before sending the configuration information to the mobile terminal, the method further includes:

The threshold value is determined according to the moving speed of the mobile terminal, the number of signaling required by the mobile terminal to transmit the location information, and the number of paging signaling that can be reduced by transmitting the location information.

The above three factors can be comprehensively considered to achieve the minimum signaling requirement or the highest reporting accuracy of the location information; generally, the larger the moving speed is, the smaller the N is, the higher the precision is; the larger N is, the more the location information is required to be transmitted. The smaller the signaling requirement, the lower the accuracy.

All base stations broadcast paging signaling to find the mobile terminal, so paging signaling can be reduced; in addition, the mobile terminal can remain in the connected state for a long time, and can be less switched between the idle state and the connected state. The signaling overhead required for the state switching is reduced. In addition, when the mobile terminal performs cell measurement and reselection in an idle state during the process of maintaining the connection state, the cell handover process will not be triggered, so no cell handover will be added. The required signaling overhead. In summary, the above technical solution can reduce the load of communication network signaling.
