Problems solved by technology

[0005] When the mobility management network element changes, the mobility management network element on the new side may inaccurately judge the user type only based on the authentication vector, and the authentication initiated by the wrong user type may cause authentication failure. Re-acquire a new authentication vector from the Home Location Register (HLR) before initiating a second authentication, thus greatly increasing the user's access delay and affecting the user experience

Embodiment 1

[0037] This embodiment describes an authentication method, through which the mobile management network element on the new side can accurately know the user type.

[0038] Describe in detail below in conjunction with accompanying drawing, see figure 1 , the method of this embodiment may include the following steps:

[0039] Step 101: The mobility management network element on the new side obtains the user type identifier or equipment capability information of the mobility management network element on the old side from the mobility management network element on the old side;

[0040] Before step 101, the old-side mobility management network element may also receive a network access request message sent by a user, where the network access request message includes a user type identifier.

[0041] Before step 101, it may also include that the old-side mobility management network element obtains the user type identifier through a request response message sent by the user data serv...

Embodiment 2

[0053] This embodiment describes that the old-side mobility management network element obtains the user type identifier by carrying the user type identifier in the network access request message sent by the user, and then the old-side mobility management network element replies to the context request message sent by the new-side mobility management network element, Carry the user type identifier in the context response message and send it to the mobility management network element on the new side.

[0054] Describe in detail below in conjunction with accompanying drawing, see figure 2 , the method of this embodiment may include the following steps:

[0055] Step 201: the user terminal equipment sends a network access request message to the old mobility management network element;

[0056] During the user's network access process, the user will send a network access request message to the old-side mobility management network element. The message carries the user type identifi...

Embodiment 3

[0080] This embodiment describes that the old-side mobility management network element obtains the user type identifier by carrying the user type identifier in the network access request message sent by the user, and the new-side mobility management network element obtains the user type identifier from the old-side mobility management network element through the location update request message. Type identification and authentication methods.

[0081] Describe in detail below in conjunction with accompanying drawing, see image 3 , the method of this embodiment may include the following steps:

[0082] Step 301: the user terminal equipment sends a network access request message to the old mobility management network element;

[0083] During the user's network access process, the user will send a network access request message to the old-side mobility management network element. The message carries the user type identifier, such as SIM or USIM. This type can be a new cell or an...

Abstract

The embodiment of the invention discloses an authentication method, a communication system and a device thereof; wherein, the authentication method comprises the steps as follows: a user type identification or the equipment capability information of an old side mobile management network element is gained from the old side mobile management network element; the user type is determined according to the user type identification or the equipment capability information of the old side mobile management network element; the authentication is issued according to the user type. As the embodiment of the invention, gains the user type identification or equipment capability information from the old side mobile management network element, exactly determines the user type according to the user type identification or the equipment capability information of the old side mobile management network element, and carries out the authentication by the exact user type, thus reducing the frequency of secondary authentication, improving the access time delay and experience of the users.

Description
