Embodiment 1

[0077] see figure 2 , a routing method is shown in the figure, and the specific steps are as follows:

[0078] Step 201, the first message sent by the AMF to the RAN, the first message includes session-related information and routing information associated with the session-related information;

[0079] The above-mentioned AMF is an access management function, or may also be called an access management function entity.

[0080] The above session-related information may be session management information, such as N2SM information.

[0081] The above routing information may be any one or more of the PDU session ID, the identifier assigned by the AMF, and the information of the SMF.

[0082] Wherein, optionally, the identifier allocated by the AMF is a temporary identifier corresponding to the session-related information allocated by the AMF when receiving the third message sent by the SMF, and the third message includes the session-related information, see Embodiment 5.

Embodiment 2

[0093] see image 3 , a routing method is shown in the figure, and the specific steps are as follows:

[0094] Step 301, the RAN sends a first message to the AMF, the first message includes session-related information and routing information associated with the session-related information, and the routing information is used by the AMF to route the session-related information to Correct SMF.

[0095] The above-mentioned AMF is an access management function, or may also be called an access management function entity.

[0096] The above session-related information may be session management information, such as N2SM information.

[0097] The above routing information is any one or more of the PDU session ID, the identifier assigned by the AMF, and the information of the SMF.

[0098] Wherein, optionally, the identifier allocated by the AMF is a temporary identifier corresponding to the session-related information allocated by the AMF when receiving the third message sent by th...

Embodiment 3

[0103] This embodiment describes the signaling process when the routing information is the PDU session ID.

[0104] see Figure 4 , the figure shows a schematic diagram of the routing process, and the specific steps are as follows:

[0105] Step 401, SMF sends N11 message to AMF, and N11 message includes N2SM information and PDU session ID.

[0106] Step 402, AMF sends N2 request message to RAN, and N2 request message includes N2SM information and PDU session ID.

[0107] In step 403, the RAN returns an N2 request confirmation message to the AMF, and the N2 request confirmation message includes the N2SM information and the PDU session ID.

[0108] In step 404, the AMF searches the context of the UE according to the PDU session ID and finds the relevant SMF, and then sends an N11 message to the SMF, and the N11 message includes N2SM information.

[0109] Routing session-related information between the RAN and the SMF is implemented through the above steps 401 to 404 .

Abstract

The embodiment of the invention provides a routing method and a routing device. The method comprises the steps as follows: an AMF receives a first message sent by a RAN, wherein the first message comprises session-related information and routing information associated with the session-related information; and the AMF routes the session-related information to a correct SMF according to the routinginformation; therefore, the information related to a routing session is achieved between the RAN and the SMF.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a routing method and device. Background technique [0002] see figure 1 , the figure shows a schematic diagram of the service request (service request) process initiated by the UE, and the specific steps are as follows: [0003] Step 1. The UE sends an MM NAS service request message to the (R)AN, and the message parameters are PDU (Protocol Data Unit, protocol data unit) session ID (identification), security parameters, and PDU session status. The UE encapsulates the NAS (Non-Access Stratum) message into an RRC (Radio Resource Control, Radio Resource Control) message, and sends it to the RAN (Radio Access Network, Radio Access Network). The parameters of the RRC message include the temporary identifier and the NAS message. If the trigger condition for the UE to execute the service request is user data generated by the upper layer, the UE includes a PDU session ID...
