Description

Method and device for obtaining paging parameters

Technical field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for obtaining paging parameters.

Background technique

In a Long Term Evolution (LTE) system, a terminal device (referred to as a terminal) has two Radio Resource Control (RRC) states—an RRC_CONNECTED state and an RRC_IDLE state. As shown in FIG. 1, in the RRC_CONNECTED state, the RRC connection (connection between the terminal and the base station) and the S1 connection (the connection between the base station and the core network) of the terminal are both present. In this way, the core network device can send data to the terminal through the two connections. In the RRC_IDLE state, the RRC connection and the S1 connection of the terminal are both interrupted, and the core network cannot send data to the terminal. In this case, if the core network has data to send to the terminal, it needs to find the terminal by triggering the paging process. As shown in the right figure of FIG. 3, the core network sends a paging request message to all base stations in the paging notification area of the terminal, and these base stations send paging messages to find the terminal. If the terminal receives the paging message from a certain base station, it initiates a random access procedure, establishes an RRC connection and an S1 connection, that is, transitions from the RRC_IDLE state to the RRC_CONNECTED state, so that the terminal can receive data from the core network.

The 5G (5th generation mobile system) communication system introduces a new state, which is different from the RRC_CONNECTED state and the RRC_IDLE state. This application is temporarily referred to as the third state. As shown in FIG. 1, the RRC connection of the terminal in this state is interrupted. That is, the connection between the terminal and the base station is interrupted; and the connection between the base station and the core network exists. In this state, the terminal cannot receive data from the core network device. However, since the connection between the base station and the core network exists, the terminal only needs to establish an RRC connection, and can transit to the RRC_CONNECTED state.

When the terminal is in the third state, the paging is not the core network device, but the base station, but currently the base station has no paging-related parameters, so the paging cannot be completed.

detailed description

A terminal device (referred to as a terminal) in the embodiment of the present application may refer to an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user. Device. The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), with wireless communication. Functional handheld devices, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminals in 5G networks, and the like.

The network device in the implementation of the present application is a network side device that performs wireless communication with the terminal device, for example, a Wireless-Fidelity (Wi-Fi) access point, a base station of a next-generation communication, such as a gNB of 5G. Or a small station, a micro station, a transmission reception point (TRP), or a relay station, an access point, an in-vehicle device, a wearable device, or the like.

The following embodiments are described by taking a base station and a terminal as an example. As shown in FIG. 2, the network system architecture involved in the method for paging parameters in the embodiment of the present invention includes a terminal, a base station, and a core network.

A new state is introduced in the 5G (5th generation mobile system) communication system, which is different from the RRC_CONNECTED state and the RRC_IDLE state. This application is temporarily referred to as the third state, and may be referred to as the RRC_INACTIVE state in the future 5G standard. As shown in FIG. 1, the connection between the terminal and the base station (RRC connection) is interrupted in this state, and the connection between the base station and the core network exists. This connection is temporarily called NG connection in 5G, and LTE. The S1 connection is similar. In this state, the terminal cannot receive data from the core network. However, since the NG connection exists, the terminal only needs to establish an RRC connection with the base station, and can transit to the RRC_CONNECTED state.

In LTE, when the core network has data to send the terminal, the core network sends a paging request message to all the base stations in the paging notification area of the terminal, and these base stations send paging messages to find the terminal, as shown in the right diagram of FIG. Shown.

When the terminal is in the third state, because the NG connection exists, the core network cannot determine whether the terminal is in the RRC_CONNECTED state or the third state. Because the core network does not know the RRC connection, the core network is unified as the RRC_CONNECTED state. . When the core network has data to send to the terminal, it will send the data to the base station without triggering the paging process. After receiving the data, the base station finds that the terminal is in the third state and cannot send data to the terminal, which triggers the paging process. As shown in the left figure of FIG. 3, the base station that triggers paging, that is, the base station that is connected last (RRC connection) before the terminal enters the third state, is called an anchor base station, and the anchor base station also remains in the context of the terminal. Information, the anchor base station sends a paging request message to all base stations in the paging notification area of the terminal, and causes the base stations to send a paging message to find the terminal. That is to say, in the third state, the paging process can be triggered by the anchor base station, which is two independent paging mechanisms with the paging process triggered by the core network mentioned above.

In order to facilitate the distinction, in this paper, we refer to the former paging mechanism as "core network triggered paging mechanism" and the latter as "base station triggered paging mechanism".

Regardless of the base station triggered paging mechanism or the core network triggered paging mechanism, the base station in the paging notification area needs to perform some paging related parameters to perform paging operations. For example, an International Mobile Subscriber Identification Number (IMSI) of the terminal, a terminal-specific discontinuous reception (DRX) period, an identifier of the terminal device, a paging notification area range of the terminal device, and the like. In the core network triggered paging mechanism, these parameters are sent by the core network to the base station in the paging notification area through a paging request message. In the base station triggered paging mechanism, since the paging is triggered by the anchor base station, these parameters need to be sent by the anchor base station to the base station in the paging notification area through the paging request message. Because there is no base station triggered paging mechanism in LTE, according to the current LTE protocol, the base station does not manage these paging parameters of the terminal. Therefore, the LTE-based paging mechanism cannot support the base station triggered paging mechanism. Therefore, there is a need to devise a method to solve the problem of missing paging parameters at the anchor base station.

The core network includes two types of devices: one is a user plane core network device, for example, a Serving GateWay (S-GW) in LTE; the other is a control plane core network device, for example, a mobility management entity in LTE (Mobility) Management Entity, MME). The user plane core network device in the 5G network is called User Plane Function (UPF), and the control plane core network device is called Access and Mobility Management Function (AMF).

In one embodiment, the user plane core network device, such as the UPF, sends data to the anchor base station of the terminal when there is data to be sent to the terminal in the third state. After receiving the data, the anchor base station knows that it cannot directly send data to the terminal, and decides to trigger the paging process. Before the paging is triggered, the paging parameter request message is sent to the control plane core network device, such as the AMF. After receiving the request message, the control plane core network device sends the paging parameter of the terminal to the anchor base station. After receiving these parameters, the anchor base station can trigger a page for the terminal.

Referring to FIG. 4, the method for obtaining paging parameters includes:

401. The user plane core network device sends the data of the terminal to the anchor base station.

The user plane core network device, such as the UPF, sends data to the anchor base station of the terminal when the data is to be sent to the terminal in the third state, and the anchor base station is the last connection before the terminal enters the third state (RRC) The base station that is connected).

402. The anchor base station sends a request message to the control plane core network device to request a paging parameter of the terminal.

The request message may be a paging parameter request message, configured to request a paging parameter of the terminal;

403. The control plane core network device sends the paging parameter of the terminal to the anchor base station.

The paging parameter shown may be carried by a paging parameter response message, and the paging parameter of the terminal may include at least one of an IMSI of the terminal, a DRX period of the terminal, an identifier of the terminal device, and a range of a paging notification area of the terminal device. The parameter, the IMSI of the terminal may only include the last N bits.

The paging parameter response message needs to include the paging parameters of the terminal. For example, the message needs to have at least several fields for carrying at least one of the following parameters:

1. The last N bits of the IMSI of the paged terminal, N may be 10 or other value.

2. The terminal-specific DRX cycle of the paged terminal. The terminal-specific DRX period is different from the cell-specific DRX period and is specific to the terminal, and different terminals in the same cell may be different.

The identifier of the paged terminal may include at least one of an IMSI, an S-TMSI, an RRC_resume ID, an AS context ID, a Paging index, and other identifiers.

4. The paging notification area range of the terminal is used to specify which base stations/cells to send paging request messages; the paging notification area range may include one or more cells.

The paging parameter response message may be a new message, or may be modified based on the existing message between the base station and the core network, for example, adding some fields to carry the above content.

After the anchor base station obtains the paging parameter of the terminal, the paging process for the terminal can be triggered.

Further, the anchor base station sends a paging request message to each base station in the paging notification area of the terminal, where the paging request message carries the obtained paging parameter of the terminal, which may include, for example, the N-bit after the IMSI of the terminal. At least one parameter, such as a terminal-specific DRX cycle, an identifier of the terminal device, and a paging notification area range of the terminal device.

Similarly, the paging request message needs to contain the paging parameters of the terminal. For example, the message needs to have at least several fields for carrying at least one of the following parameters:

4. The paging notification area range of the terminal is used to specify which base stations/cells to send paging request messages.

The terminal paging notification area may be determined by the anchor base station according to the obtained paging parameter of the terminal, and it is also possible that the anchor base station has been known in advance.

Through the method of the embodiment, the anchor base station can obtain a paging parameter required to trigger a paging procedure for a specific terminal, which is convenient for triggering a paging procedure for the terminal.

In another embodiment, when the terminal initially accesses the base station, the base station may acquire the paging parameter of the terminal in advance. For example, after the terminal accesses the base station through the random access procedure, the base station sends a request message, such as a user initialization message to the core network device to request the user context of the terminal. After receiving the request message, the core network device sends the user context (including the paging parameters) to the base station. The base station can then use these parameters when triggering the paging process of the terminal.

First, the terminal completes the cell access through the random access procedure, that is, the eNB receives the RRC connection setup acknowledgement message sent by the terminal, such as the RRCConnectionSetupComplete message in the LTE, indicating that the terminal has accessed the base station. The base station then sends a request message to the core network device, such as a user initialization message, which has the function of requesting the user context of the terminal. After receiving the request message, the core network device sends a response message to send the user context of the terminal to the base station. The above procedure has been defined in the LTE, but the terminal context does not include the paging parameter of the terminal. In this embodiment, the paging parameter of the terminal is also included in the context of the user sent by the core network device to the terminal.

In another embodiment, the terminal sends a NAS service request to the base station, and the NAS service request is forwarded to the core network device, and after receiving the core network device, the paging parameter of the terminal is sent to the base station; the method may be applied to the terminal. The scenario of the initial access to the base station can also be used in other scenarios, such as a handover scenario of the terminal, a location update scenario, and the like.

As shown in FIG. 5, the method for obtaining paging parameters includes:

501. The base station receives a NAS service request sent by the terminal.

The base station may receive the NAS service request sent by the terminal in the random access process of the terminal; the random access process of the terminal is a prior art, and is not described in detail. In this process, the terminal sends a NAS service request to the base station;

The terminal completes the cell access through the random access procedure. The eNB establishes an RRC connection setup acknowledgement message, such as the RRCConnectionSetupComplete message in the LTE, indicating that the terminal's random access procedure has been completed.

The RRC Connection Setup Confirmation/Completion message may carry a NAS service request sent by the terminal to the base station.

In addition, the base station may also receive the NAS service request sent by the terminal in other processes, for example, the terminal network attachment process, the terminal location update process, and the terminal performing the handover process.

In another embodiment, the eNB receives the RRC connection setup acknowledgement/completion message sent by the terminal, indicating that the base station completes the random access procedure of the terminal, and the RRC connection setup acknowledgement/completion message may not carry the NAS service request.

502. The base station sends a NAS service request to the core network device.

The base station sends a request message to the core network device, where the NAS service request is carried. For example, the request message is a user initialization message; the function of the user initialization message includes requesting the context of the terminal device, and may have other functions.

After receiving the NAS service request sent to the core network carried in the RRC connection establishment confirmation/completion message, the base station sends the NAS service request to the core network, and the NAS service request may be carried in the user initialization message.

The core network device is usually a core network control plane device, and the context of the terminal is also referred to as a user context.

In another embodiment, the base station may not send the request message to the core network device or carry the NAS service request.

503. After receiving the NAS service request sent by the base station, the core network device sends a paging parameter of the terminal to the base station.

For example, after receiving the NAS service request in the user initialization message, the core network device sends a paging parameter of the terminal to the base station, and the paging parameter may be carried in the user context of the terminal. in.

In another embodiment, after receiving the message sent by the base station for requesting the context, the core network device sends the user context to the terminal, where the paging parameter of the terminal is carried; the message for requesting the context is also You may not carry a NAS service request.

The content of the paging parameter is similar to the foregoing embodiment, and may include at least one parameter such as an IMSI of the terminal, a terminal-specific DRX cycle, an identifier of the terminal device, a paging notification area range of the terminal device, and an IMSI of the terminal. It can only include the last N bits, etc., and will not be described in detail.

After the base station obtains the paging parameter of the terminal, the base station can trigger a paging procedure for the terminal.

Further, the base station sends a paging request message to each base station in the paging notification area of the terminal, where the paging request message carries the obtained paging parameter of the terminal, which may include, for example, the IMSI of the terminal and the IMSI of the terminal. At least one parameter of the last N bits, the terminal-specific DRX cycle, the identity of the terminal device, and the paging notification area range of the terminal device.

The terminal paging notification area may be determined by the base station according to the obtained paging parameter of the terminal, and it is also possible that the base station has been known in advance.

The foregoing embodiment uses the terminal random access procedure as an example to describe a method for the base station to obtain the paging parameter. In addition to the scenario sequence discussed above, the base station may also obtain the paging parameter of the terminal in other scenarios, for example:

1. The terminal network attachment process: after the terminal completes the network attachment, the core network sends the paging parameter of the terminal to the base station;

2. Terminal location update process: After the terminal reports the location update to the core network, the core network sends the paging parameters of the terminal to the base station.

3. The terminal performs the handover process: after the terminal switches to the target base station, the target base station acquires paging parameters from the core network.

Through the method of the foregoing embodiment, the base station can obtain a paging parameter required to trigger a paging procedure for a specific terminal, which is convenient for triggering a paging procedure for the terminal.
