Problems solved by technology

[0009] However, the connection management function is independent of the mobility management function and also independent of the session management function. Therefore, whether the connection management function is set in the logical entity of the mobility management function or the logical entity of the session management function, it will affect mobility management Coupling of the logical entity of the function and the logical entity of the session management function
[0010] In the related art, setting the connection management function in the logical entity of the mobility management function or the logical entity of the session management function affects the coupling of the two logical entities, and no effective solution has been proposed yet

Embodiment 1

[0167] Figure 12 is a schematic diagram of a UE registration method according to an optional embodiment of the present invention. Such as Figure 12 As shown, the method includes the following steps:

[0168] Step 1201, the user equipment UE sends an RRC establishment request message to the RAN, and the request message carries a registration request.

[0169] In step 1202, the RAN sends a NAS transmission message to the connection management function entity, and carries a registration request in the message.

[0170] Step 1203, the connection management function entity creates the connection management context of the UE.

[0171] Step 1204, the connection management function entity selects a logical entity of MMF according to the identifier of the user equipment, and sends the registration request in the NAS message to the logical entity of MMF.

[0172] Step 1205, the logical entity of the MMF sends the NAS message carrying the registration acceptance message to the conn...

Embodiment 2

[0176] Figure 13 is a schematic diagram of a user equipment service request method according to an optional embodiment of the present invention. Such as Figure 13 As shown, the method includes the following steps:

[0177] Step 1301, the user equipment UE sends an RRC establishment request message to the RAN, and the request message carries a service request.

[0178] In step 1302, the RAN sends a NAS transmission message to the connection management function entity, and the message carries a service request.

[0179] Step 1303, the connection management function entity creates the connection management context of the UE.

[0180] Step 1304, the connection management functional entity selects a logical entity of MMF according to the identification of the user equipment, and sends the NAS message carrying the service request message to the logical entity of the MMF.

[0181] Step 1305, the logical entity of the MMF sends a NAS message carrying the service request to the l...

Embodiment 3

[0188] Figure 14 is a schematic diagram of a method for releasing a connection of a user equipment according to an optional embodiment of the present invention. Such as Figure 14 As shown, the method includes the following steps:

[0189] Step 1401, when the RAN triggers the connection release, the RAN sends a connection release request message to the connection management functional entity.

[0190] Step 1402, the connection management function entity sends a connection release request message to the logical entity of the MMF.

[0191] Step 1403, the logic entity of the MMF sends the connection release command message to the connection management function entity.

[0192] Step 1404, the connection management functional entity deletes the connection management context of the UE.

[0193] Step 1405, the connection management function entity sends a connection release complete message to the logical entity of the MMF.

[0194] Step 1406, the logical entity of the MMF send...

Abstract

The present invention provides a network system. The network system comprises a connection management functional entity which is connected with an RAN and a mobility management entity and is used formaintaining the connection status of user equipment (UE), wherein the mobility management entity comprises at least one of the logical entity of a mobility management function (MMF) and the logical entity of a session management function (SMF). According to the prior art, a connection management function is set in the logical entity of a mobility management function or the logical entity of a session management function, and as a result, coupling between two the logical entities is affected, while with the network system adopted, the problem in the prior art can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network system. 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 is a schematic diagram of the 4G network architecture in related technologies, such as figure 1 As shown, the functions of each network element in the network architecture are as follows: [0003] The terminal (User Equipment, referred to as UE) 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 communicates with the core network Mobility management entity interaction information; [0004] The base station (Radio Access Network, RAN) is responsible for air interface resource scheduling and air interface connection management fo...
