Description

Information processing method and device
Technical Field
The present application relates to communications technologies, and in particular, to an information processing method and apparatus.
Background
An Evolved Packet System (EPS) session is a connection based on an Internet Protocol (IP), and specifically relates to association between a User Equipment (UE) and an IP network. One EPS session is composed of one or more IP connection Access Network (IP-CAN) bearers (EPS bearers), where the EPS bearer is a logical set of one or more service Data flows between a UE and a Public Data GateWay (PGW), and includes three parts, i.e., a radio bearer, an S1 bearer, and an S5/S8 bearer.
In the management procedure of the EPS session described above, modification of the context of the EPS bearer is often involved. Context of EPS session needs to be synchronized in UE, core network node, PGW, Serving GateWay (SGW for short), that is, it is ensured that context information of EPS bearer obtained at both ends of UE and core network is the same. The establishment, modification and deletion of the EPS bearer context may be initiated by the UE or may be initiated by the network side. For a session management request initiated by the UE, the UE and the network side may synchronously maintain session information, and when the network side modifies the session information, for example, modifies a certain Quality of service (QoS) or a Traffic Flow Template (TFT), the network side needs to timely notify the modified session information to the UE; if the UE is in an idle state, a Mobility Management Entity (MME) or a Serving GPRS Support Node (SGSN) initiates a paging procedure to the UE, so that the UE enters a connected state, and the MME or the SGSN synchronizes modified session information to the UE in time through a Radio Access Network (RAN).
However, when the connection between the UE and the radio access network is disconnected, the above information synchronization process may cause additional signaling overhead for some specific network-initiated modification procedures or session modification commands that do not need to be synchronized to the UE in time.

In a first aspect, the present application provides an information processing method, where after a network device receives a first message including first information that can be sent to a terminal device in a delayed manner, when the network device determines that the terminal device is in an RRC inactive state, the network device stores the first information in the first message first, and after the network device determines that a terminal requests to establish a wireless connection, the network device sends the first information in the first message to the terminal device, so that the terminal device performs context synchronization according to the first information, thereby avoiding a network side from initiating an unnecessary paging instruction to the terminal device, and further reducing signaling overhead.

Optionally, the network device may be AN node or a core network device, and when the network devices are different, the processing procedures for information (for example, processing procedures for sending the first information, the first indication information, and the like) are also different. For example, at least two possible implementations may be included as follows:
one possible implementation is: the network device is a first AN node.
In this possible implementation manner, the first AN node may send the first indication information to the terminal device through the following possible implementation manners:

The AN node accessed after the terminal equipment enters the connection state is the second AN node, therefore, after the second AN node judges that the terminal triggers and establishes wireless connection, the second AN node can request the first AN node to acquire the first information through the core network equipment and send the first information to the terminal equipment, so that the terminal equipment carries out context synchronization according to the first information, and thus, the network side is prevented from initiating unnecessary paging instructions to the terminal equipment, and the signaling overhead is reduced.

It should be noted that, in an actual application process, the present application may also be applied to other scenarios, for example, the scenario shown in fig. 1B, and fig. 1B is a schematic view of an application scenario of the information processing method provided by the present application. With respect to fig. 1A, fig. 1B further includes a network open function (NEF) entity and a network function storage function (NRF) entity, and the same entities as those in fig. 1A are not described again here. In practical applications, the names of messages exchanged between entities in the network architecture shown in fig. 1B may be different relative to the network architecture shown in fig. 1A.
In the application, after the network side device modifies the context information of the user equipment, if the terminal device is determined to be in the RRC inactive state, the modified information is stored in the corresponding node. And after judging that the terminal equipment triggers and establishes wireless connection, sending the corresponding node storage modified information to the terminal equipment so that the terminal equipment updates the context of the user equipment according to the received modified information, avoiding a network side from initiating unnecessary paging instructions and further reducing signaling overhead.

It should be noted that the following specific embodiments may be combined with each other, and description of the same or similar contents is not repeated in different embodiments.
Fig. 2 is a first schematic flow chart of an information processing method provided in the present application. Referring to fig. 2, the method may include:
s201, the network device receives a first message, wherein the first message comprises first information sent to the terminal device, and the first information is information capable of being sent in a delayed mode.
Optionally, the network device may be AN node, and may also be a core network device, where the core network device may be AN AMF entity, AN SMF entity, and the like. Optionally, the network device may not necessarily send the first information in the first message to the terminal device after receiving the first information, where the first information may be sent to the terminal device with a delay.
Optionally, the first message is a message that can be processed asynchronously, and the first message may not be processed immediately after the network device receives the first message. That is, after the network device receives the first message, other tasks may be performed first, and the first message is processed when needed or possible.
The first message comprises first information sent to the terminal equipment, and the first information is information capable of being sent in a delayed mode. Optionally, the first information may be PDU session context modification information or mobility-related context modification information or policy information of the UE.

Optionally, the asynchronous indication may be a displayed indication or an implicit indication, and the asynchronous indication is added to the first message by the network element initiating the N2 message.
S202, when the network equipment determines that the terminal equipment is in a Radio Resource Control (RRC) inactive state, first information is stored.
When the terminal equipment is in AN RRC inactive state, no air interface connection is established between the terminal equipment and the AN node, but connection still exists between the AN node and the UPF and between the AN node and the AMF entity.
Optionally, when the network device receives the first message and the network device determines that the terminal device is in the RRC inactive state, the network device stores the first information in the first message.
S203, after the terminal equipment requests to establish the wireless connection, the network equipment sends first information to the terminal equipment.
Optionally, when the terminal device is in the RRC inactive state, the terminal device may request to establish a wireless connection according to actual needs. For example, when the terminal device has uplink data to be sent, or the terminal device has signaling to be executed, or the terminal device receives paging signaling, or the terminal device reaches a preset sending time, or the like, the terminal device may trigger the establishment of the wireless connection, and certainly, in other cases, the terminal device may also request the establishment of the wireless connection.

Correspondingly, when the first indication information indicates that the terminal suspends sending uplink signaling or data, the terminal device may suspend sending uplink data when the terminal device receives the first indication information. It should be noted that, in an actual application process, the first indication information may also indicate the terminal device to perform other actions, which is not specifically limited in this application.
According to the information processing method, after the network equipment receives the first message comprising the first information which can be sent in a delayed mode, when the network equipment judges that the terminal equipment is in an RRC inactive state, the network equipment stores the first information in the first message, and after the network equipment determines that the terminal requests to establish wireless connection, the network equipment sends the first information in the first message to the terminal equipment, so that the terminal equipment performs context synchronization according to the first information, therefore, the network side is prevented from initiating unnecessary paging instructions to the terminal equipment, and signaling overhead is reduced.

Optionally, the N2 request message may include the first information corresponding to the terminal device and the asynchronous indication, for example, the first information may be context modification information, such as the N1 message. The N2 request message in the embodiment of fig. 3 may be the first message in the embodiment of fig. 2.
Optionally, the core network device may be an AMF entity.
Alternatively, the AMF entity may determine to send the N2 request message to the first AN node according to local policy. The AMF entity may also determine to send AN N2 request message to the first AN node after receiving the request from the UDM/PCF/SMF or the like. The AMF entity may also determine to send AN N2 request message to the first AN node after receiving a Session Management (SM) request sent by the SMF, where the SMF may initiate a Session Management (SM) request to the AMF after receiving the request according to a local policy or from the UDM/PCF, or the like.
Optionally, the AMF carries an asynchronous indication in the N2 request message, where the asynchronous indication is used to indicate that the first information in the N2 request message is information that can be sent with a delay. Further, the AMF determines to carry the asynchronous indication in the N2 message according to the asynchronous indication in the received first message, or the AMF determines to carry the asynchronous indication in the N2 request message according to the received message and/or a local policy.

It should be noted that, if the first AN node determines that the first information in the N2 request message is not information that can be sent with a delay, the first AN initiates a paging procedure to the UE, so that the UE enters AN RRC active state to send the first information to the UE. Or, when the terminal device is not in the RRC inactive state, the first AN node directly sends the N2 request message to the terminal device, or performs other processing on the N2 request message, which is not specifically limited in this application.

Optionally, the first AN node may send AN N2 request acknowledgement message to the AMF.
If the N2 request message is sent by the AMF to the first AN node after receiving a request from the UDM/PCF or according to local policy, the AMF marks that the N2 request message is not executed after receiving the N2 request confirm message. Further optionally, the AMF does not initiate a new N2 request to the AN containing information that can delay sending until the un-executed N2 request execution completes or the AMF determines that the UE is in RRC active state.
If the N2 request message is sent to the first AN node after the request received by the SMF to or from the UDM/PCF according to the local policy, the AMF sends the N2 request acknowledge message to the SMF after receiving the N2 request acknowledge message, and the SMF marks that the N2 request message is not executed. Further optionally, the SMF does not initiate an N2 request containing information that can be delayed from being sent until the SMF determines that the UE is in the RRC-active state.

The first indication information is used for indicating that the first AN node stores the first information. After the terminal device receives the first indication information, the terminal device performs an action corresponding to the first indication information, for example, the first indication information may indicate that the terminal device suspends sending uplink data or instructions.
S306, the first AN node sends a wireless air interface message to the terminal equipment, wherein the wireless air interface message comprises the first information.
Optionally, when the first AN node generates the wireless air interface message, it may be determined that the last information that can be sent with delay is generated, and if yes, the wireless air interface message carries second indication information, where the second indication information is used to indicate, to the terminal device, that the N2 request message is the last information that can be sent with delay and stored by the first AN.
And S307, the terminal equipment synchronizes the context information according to the first information in the wireless air interface message.
That is, the terminal device updates the locally stored context information according to the first information in the wireless air interface.

The second indication information is used to indicate that the processed first information is the last first information corresponding to the terminal device, that is, the first information sent by the first AN node to the terminal device is the last first information on the first AN node.
S310, the first AN node sends AN N2 response message to the core network equipment.
The N2 response message is used to notify the core network device that the terminal device has completed the synchronization of the first information.
Optionally, if the N2 request message is sent to the first AN node after the request received by the SMF to or from the UDM/PCF according to the local policy, the core network device AMF sends the N2 response message to the SMF after receiving the N2 response message.
