Problems solved by technology

[0022] In a user process, an NF will interact with other NFs multiple times. If each interaction needs to read and write user data to CUDB, it will increase the network load on the one hand, and increase the process completion on the other hand. delay

Embodiment 1

[0073] Embodiment one: if Figure 4 Shown is one embodiment of the attach process.

[0074] In step 401, the UE sends an attach request message to the CP, carrying the IMSI, and the forwarding module in the CP selects instance 1 (CP1) to process the message.

[0075] Step 402, CP1 sends a read user data request message to CUDB, requesting all data of the user.

[0076] In step 403, CUDB returns a read user data response message to CP1, carrying user data and status information.

[0077] Step 404, CP1 creates MM context and so on.

[0078] Step 405, CP1 completes security functions and so on for the user.

[0079] In step 406, CP1 sends an attach acceptance message to UE, and the message carries information such as user temporary ID, temporary routing information of the processing instance, and the like.

[0080] Step 407, the UE returns an attach complete message to the CP, the message carries the temporary routing information of the processing instance in the request mess...

Embodiment 2

[0084] Embodiment two: if Figure 5 Shown is one embodiment of a service request process.

[0085] In step 501, the UE sends a service request message to the CP, and the forwarding module in the CP selects instance 1 (CP1) to process the message.

[0086] Step 502, CP1 sends a read user data request message to CUDB, requesting all data of the user.

[0087] In step 503, CUDB returns a read user data response message to CP1, carrying user data and status information.

[0088] Step 504, CP1 sends a wireless tunnel establishment request message to the RAN, and the message carries temporary routing information of the processing instance.

[0089] Step 505, the RAN returns a wireless tunnel establishment response message to the CP, the message carries the temporary routing information of the processing instance in the request message, and the forwarding module in the CP selects CP1 to process the message according to the temporary routing information of the processing instance. ...

Embodiment 3

[0097] Embodiment three: as Image 6 Shown is one embodiment of the PDU session establishment process.

[0098] In step 601, the UE sends a session establishment request message to the CP, and the forwarding module in the CP selects instance 1 (CP1) to process the message.

[0099] Step 602, CP1 sends a read user data request message to CUDB, requesting all data of the user.

[0100] In step 603, CUDB returns a read user data response message to CP1, carrying user data and status information.

[0101] Step 604, CP1 creates a session context, selects UP and so on.

[0102] Step 605, CP1 sends a user plane establishment request message to the UP, and the message carries temporary routing information of the processing instance.

[0103]In step 606, the UP returns a user plane establishment response message to the CP, which carries the temporary routing information of the processing instance in the request message, and the forwarding module in the CP selects CP1 to process the ...

Abstract

The present invention discloses a method and device for stateless processing by a network functional entity. The method includes: a first network functional entity selects a processing instance for a user processing flow, and obtains user data and state information through the processing instance; When the first network function entity uses the processing instance to send a request message to the second network function entity, the request message carries the routing information of the processing instance; the first network function entity receives the second When the network function entity sends a response message, extract the routing information of the processing instance from the response message; forward the response message to the processing instance according to the routing information of the processing instance.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and device for stateless processing by a network function entity. Background technique [0002] Mobile communication has now developed to the 4G stage. Compared with the previous generations, the 4G network architecture is mainly characterized by all-IP transmission. figure 1 It is a 4G network architecture. The functions of each network element in the 4G network architecture are as follows: [0003] The terminal (UE, User Equipment) mainly accesses the 4G network through the wireless air interface and obtains services. The terminal exchanges information with the base station through the air interface, and through non-access stratum signaling (NAS, Non-Access Stratum) and core network mobility management Entity (MME, Mobility Management Entity) exchange information. [0004] The base station (RAN, Radio Access Network) is responsible for air interface resource sche...
