Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for acquiring a paging parameter.
Background
In a Long Term Evolution (LTE) system, a terminal device (abbreviated as a terminal) has two Radio Resource Control (RRC) states, namely, an RRC _ CONNECTED state and an RRC _ IDLE state. As shown in fig. 1, in the RRC _ CONNECTED state, both RRC connection of the terminal (connection between the terminal and the base station) and S1 connection (connection between the base station and the core network) exist. Thus, the core network device can send data to the terminal through the two connections. In the RRC _ IDLE state, both the RRC connection and the S1 connection of the terminal are interrupted, and the core network cannot transmit 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 a paging procedure. Specifically, as shown in the right diagram of fig. 3, the core network sends a paging request message to all base stations in the paging notification area of the terminal, so that the base stations send paging messages to search for the terminal. If the terminal receives a paging message from a base station, it initiates a random access procedure to establish an RRC connection and an S1 connection, i.e. to transition from an RRC _ IDLE state to an RRC _ CONNECTED state, so that the terminal can receive data from the 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, and is temporarily referred to as a third state in the present application, 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; while a connection between the base station and the core network exists. In this state, the terminal cannot receive data from the core network device, but since a connection between the base station and the core network exists, the terminal can transition to the RRC _ CONNECTED state only by establishing an RRC connection.
When the terminal is in the third state, the base station is not the core network device but the base station which triggers paging, but the base station does not have parameters related to paging at present, so that paging cannot be completed.

Detailed Description
A terminal device (simply terminal) in the embodiments of the present application may refer to an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. An 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), a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, a terminal in a 5G network, etc.
The network device in this embodiment is a network side device that performs Wireless communication with the terminal device, for example, an access point of Wireless-Fidelity (Wi-Fi), a base station of next-generation communication, such as a gbb or a small station of 5G, a micro station, a Transmission Reception Point (TRP), a relay station, an access point, a vehicle-mounted device, a wearable device, and the like.
The following embodiments are described with reference to a base station and a terminal as examples. As shown in fig. 2, a network system architecture related to 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, and is temporarily referred to as a third state in the present application, and may be referred to as an RRC _ INACTIVE state in the 5G standard in the future. As shown in fig. 1, in this state, the connection between the terminal and the base station (RRC connection) is broken, while the connection between the base station and the core network exists, which is temporarily referred to as an NG connection in 5G, similar to the S1 connection in LTE. In this state, the terminal cannot receive data from the core network, but since the NG connection is present, the terminal can transition to the RRC _ CONNECTED state only by establishing an RRC connection with the base station.
In LTE, when the core network has data to send the terminal, the core network sends a paging request message to all base stations in the paging notification area of the terminal, and the base stations send paging messages to search for the terminal, as shown in the right diagram of fig. 3.
When the terminal is in the third state, since 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 condition, and thus 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 procedure. After receiving the data, the base station finds that the terminal is in the third state, cannot send the data to the terminal, and triggers a paging process. Specifically, as shown in the left diagram of fig. 3, the base station triggering paging, that is, the base station that is last connected (RRC connected) before the terminal enters the third state, is called an anchor base station, the anchor base station also retains the context information of the terminal, and the anchor base station sends a paging request message to all base stations in the paging notification area of the terminal, so that the base stations send a paging message to search for the terminal. That is, in the third state, the paging procedure may be triggered by the anchor base station, which is two independent paging mechanisms from the above-mentioned core network triggered paging procedure.
For the sake of distinction, the former paging mechanism is referred to as a "core network triggered paging mechanism" and the latter is referred to as a "base station triggered paging mechanism".
Whether the base station triggered paging mechanism or the core network triggered paging mechanism, the base stations in the paging notification area need some paging related parameters to perform the paging operation. For example, the terminal may include an International Mobile Subscriber Identity (IMSI) of the terminal, a terminal-specific Discontinuous Reception (DRX) cycle, an identifier of the terminal, a paging notification area range of the terminal, and the like. In the core network triggered paging mechanism, these parameters are sent by the core network to the base stations in the paging notification area through a paging request message. In the base station triggered paging mechanism, since paging is triggered by the anchor base station, these parameters need to be sent by the anchor base station to the base stations in the paging notification area through a paging request message. Because there is no base station triggered paging mechanism in LTE, the base station does not manage these paging parameters for the terminal according to the current LTE protocol. Therefore, the LTE-based paging mechanism cannot support the base station triggered paging mechanism. Therefore, a method needs to be designed to solve the problem that the anchor base station lacks the paging parameters.
The core network includes two kinds of devices: one is a user plane core network device, for example: serving gateway (S-GW) in LTE; second, a control plane core network device, for example: mobility Management Entity (MME) in LTE. In the 5G network, the User plane core network device is called a User Plane Function (UPF), and the control plane core network device is called an Access and mobility management entity (AMF).
In one embodiment, when the user plane core network device, such as the UPF, has data to send to the terminal in the third state, the user plane core network device sends the data to the anchor base station of the terminal. And the anchor base station knows that the data can not be directly sent to the terminal after receiving the data, and decides to trigger a paging process. Before triggering paging, it sends a paging parameter request message to a control plane core network device, such as an AMF, and after receiving the request message, the control plane core network device sends the paging parameter of the terminal to the anchor base station. The anchor base station may trigger paging for the terminal upon receiving the parameters.
Referring to fig. 4, the method for acquiring paging parameters includes:
401. the user plane core network equipment sends the data of the terminal to the anchor point base station;
when the user plane core network device, such as the UPF, has data to send to the terminal in the third state, the data is sent to the anchor base station of the terminal, and the anchor base station is the base station that is connected last (RRC connection) before the terminal enters the third state.
402. The anchor point base station sends a request message to the control plane core network equipment to request the paging parameters of the terminal;
the request message may be a paging parameter request message for requesting a paging parameter of the terminal;
403. the control plane core network equipment sends the paging parameters of the terminal to the anchor point base station;
the paging parameter may be carried in a paging parameter response message, and the paging parameter of the terminal may include: the terminal IMSI, the terminal-specific DRX cycle, the terminal device identifier, the paging notification area range of the terminal device, and the like, where the terminal IMSI may include only the last N digits.
The paging parameter response message needs to contain the paging parameters of the terminal. For example, the message at least needs to have several fields, which are respectively used to carry at least one of the following parameters:
1. the last N bits of the IMSI of the terminal being paged, N may be 10 or some other value.
2. Terminal specific DRX cycle of the paged terminal. The terminal-specific DRX cycle is different from the cell-specific DRX cycle, and is terminal-specific, and different terminals may be different within the same cell.
3. The identification of the terminal to be paged may include at least one of an IMSI, an S-TMSI, an RRC _ resume ID, an AS context ID, a Paging index, and other identifications.
4. The paging notification area range of the terminal is used for appointing which base stations/cells 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-mentioned content.
After obtaining the paging parameters of the terminal, the anchor point base station may trigger a paging process for the terminal.
Further, the anchor base station sends a paging request message to each base station in the paging notification area range of the terminal, where the paging request message carries the obtained paging parameters of the terminal, and the paging request message may include, for example: n digits after IMSI of the terminal, terminal specific DRX period, terminal equipment identification, terminal equipment paging notification area range and the like.
Similarly, the paging request message needs to contain the paging parameters of the terminal. For example, the message at least needs to have several fields, which are respectively used to carry at least one of the following parameters:
1. the last N bits of the IMSI of the terminal being paged, N may be 10 or some other value.
2. Terminal specific DRX cycle of the paged terminal. The terminal-specific DRX cycle is different from the cell-specific DRX cycle, and is terminal-specific, and different terminals may be different within the same cell.
3. The identification of the terminal to be paged may include at least one of an IMSI, an S-TMSI, an RRC _ resume ID, an AS context ID, a Paging index, and other identifications.
4. The paging notification zone range of the terminal is used for specifying which base stations/cells send paging request messages.
The paging notification area range of the terminal may be determined by the anchor base station according to the obtained paging parameters of the terminal, or may be known by the anchor base station in advance.
By the method of the embodiment, the anchor base station can obtain the paging parameters required for triggering the paging process for the specific terminal, so that the paging process for the terminal is conveniently triggered.
In another embodiment, when the terminal initially accesses the base station, the base station may acquire the paging parameters of the terminal in advance. For example: after the terminal accesses the base station through the random access process, 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 may use these parameters to trigger the paging procedure for the terminal.
First, the terminal completes cell access through a random access process, that is, the base station receives an RRC connection setup confirm message sent by the terminal, such as an RRCConnectionSetupComplete message in LTE, indicating that the terminal has accessed the base station. The base station then sends a request message, such as a user initialization message, to the core network device, the message having the function of requesting the user context of the terminal. And after receiving the request message, the core network equipment sends a response message and sends the user context of the terminal to the base station. The above procedure has been defined in LTE, but the terminal context does not include the paging parameters of the terminal; in this embodiment, the user context sent to the terminal by the core network device further includes a paging parameter of the terminal.
In another embodiment, the terminal sends an NAS service request to the base station, the base station forwards the NAS service request to the core network device, and the core network device sends the paging parameter of the terminal to the base station after receiving the NAS service request; the method can be applied to the scene that the terminal initially accesses the base station, and can also be applied to other scenes, such as a terminal switching scene, a location updating scene and the like.
As shown in fig. 5, the method for acquiring paging parameters includes:
501. a base station receives an NAS service request sent by a terminal;
the base station can receive an NAS service request sent by the terminal in the random access process of the terminal; the random access process of the terminal is the prior art, and is not detailed, and the terminal sends an NAS service request to a base station in the process;
the terminal completes cell access through a random access process, and usually, the base station receives an RRC connection setup confirm message sent by the terminal, such as an RRCConnectionSetupComplete message in LTE, which indicates that the random access process of the terminal is completed.
The RRC connection setup confirm/complete message may carry a NAS service request that the terminal sends to the base station.
In addition, the base station may receive the NAS service request transmitted by the terminal in another process, for example: a terminal network attachment process, a terminal position updating process and a terminal switching process.
In another embodiment, the base station receives an RRC connection setup confirm/complete message sent by the terminal, which indicates that the base station completes the random access procedure of the terminal, and the NAS service request may not be carried in the RRC connection setup confirm/complete message.
502. A base station sends an NAS service request to core network equipment;
and the base station sends a request message to the core network equipment, wherein the request message carries the NAS service request. For example, the request message is a user initialization message; the function of the user initiated message includes requesting the context of the terminal device, as well as other functions.
After receiving the NAS service request sent to the core network and carried in the RRC connection setup confirm/complete message, the base station sends the NAS service request to the core network, where the NAS service request may be carried in a user initialization message.
The core network device is generally 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 send the request message to the core network device without carrying the NAS service request.
503. And after receiving the NAS service request sent by the base station, the core network equipment sends the 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 a user context of the terminal.
In another embodiment, after receiving a message for requesting context sent by a base station, the core network device sends a user context to a terminal, where the user context carries a paging parameter of the terminal; the message for requesting context may not carry a NAS service request.
The content of the paging parameters, similar to the aforementioned embodiment, may include: the IMSI of the terminal, the terminal-specific DRX cycle, the identifier of the terminal device, the paging notification area range of the terminal device, and the like, may include only the last N digits, and the like, and will not be described in detail.
After obtaining the paging parameters of the terminal, the base station may trigger a paging process for the terminal.
Further, the base station sends a paging request message to each base station in the paging notification area range of the terminal, where the paging request message carries the obtained paging parameters of the terminal, and the paging request message may include, for example: the terminal device comprises at least one parameter of IMSI of the terminal, last N digits of the IMSI of the terminal, a terminal specific DRX period, an identification of the terminal device, a paging notification area range of the terminal device and the like.
The paging notification area range of the terminal may be determined by the base station according to the obtained paging parameters of the terminal, or may be known by the base station in advance.
In the above embodiment, the method for acquiring the paging parameter by the base station is described by taking the terminal random access procedure as an example, except for the scenario procedure discussed above, the base station may acquire the paging parameter of the terminal in other scenarios, for example:
1. and (3) a terminal network attachment process: after the terminal completes network attachment, the core network sends the paging parameters of the terminal to the base station;
2. and (3) terminal position updating process: after the terminal reports the position update to the core network, the core network sends the paging parameter of the terminal to the base station.
3. The terminal carries out a switching process: and after the terminal is switched to the target base station, the target base station acquires the paging parameters from the core network.
By the method of the embodiment, the base station can obtain the paging parameters required for triggering the paging process for the specific terminal, so that the paging process for the terminal is triggered conveniently.
