Problems solved by technology

Since the source-side mobility management NE saves the security context in both the GERAN / UTRAN network and the E-UTRAN network, when the target-side mobility management NE obtains the context, the source-side mobility management NE cannot provide a suitable security context , when the target-side mobility management network element has no security context or does not have a suitable security context, the target-side mobility management network element needs to interact with the HSS to obtain the security context, which increases the interaction load with the HSS

Embodiment 1

[0044] In this embodiment, the UE first attaches to the source-side mobility management network element, and the source-side mobility management network element simultaneously stores security contexts in the GERAN / UTRAN network and the E-UTRAN network. When the UE initiates the routing area update procedure or the tracking area update procedure, during the context transfer process between the source-side mobility management NE and the target-side mobility management NE, the target-side mobility management NE can send the context request message Carry information indicating the type of equipment, such as Supported RAT (Supported Radio Access Type), inform the source-side mobility management network element of its own device type, so that the source-side mobility management network element according to the target side The device type of the mobility management network element transfers the security context of the corresponding UE; or the mobility management network element of the...

Embodiment 2

[0076] In this embodiment, the UE first attaches to the source-side mobility management network element, and the source-side mobility management network element simultaneously stores security contexts in the GERAN / UTRAN network and the E-UTRAN network. When the UE separates from the source-side mobility management network element and wants to change the attachment object, the UE needs to execute the attach process and send an attach request message to the target-side mobility management network element, which carries the user’s temporary identifier. The mobility management network element needs to obtain the IMSI and security context from the source-side mobility management network element, and the source-side mobility management network element needs to transfer different UE security contexts according to the device type of the target-side mobility management network element.

[0077] based on the following image 3 The method for providing a security context provided in this...

Embodiment 3

[0096] see Figure 4 , this embodiment provides a mobility management network element, where the mobility management network element includes:

[0097] The first receiving module 41 is configured to receive a request message carrying indication information sent by a target-side mobility management network element;

[0098] The first sending module 43 is configured to send the security context of the user equipment corresponding to the indication information to the target-side mobility management network element.

[0099] Wherein, the indication information in the request message includes information indicating the device type of the target-side mobility management network element or information indicating the type of security context of the user equipment that the target-side mobility management network element needs to obtain.

[0100] Wherein, the first sending module 43 includes:

[0101] The first sending unit is configured to indicate that the device type of the target-...

Abstract

The invention provides a method for providing security context, a mobile management network element and a mobile communication system, belonging to the field of communications.The method comprises the following steps: receiving request messages carrying instruction information, which is transmitted by the mobile management network element at the target side; transmitting user facility security context corresponding to the instruction information to the mobile management network element at the target side.In the embodiment of the invention, as the request messages transmitted from the mobile management network element at the target side to the mobile management network element at the source side carries the instruction information, so that the mobile management network element at the source side can transmit the security context corresponding to the instruction information to the mobile management network element at the target side according to the instruction information in the request messages, thus avoiding the process where the mobile management network element at the target side interacts with HSS to obtain the security context, reducing interaction load with the HSS.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for providing a security context, a mobility management network element and a mobile communication system. Background technique [0002] The core network of the wireless evolved network mainly includes three logical functional bodies: a Mobility Management Entity (MME, Mobility Management Entity), a Serving Gateway (Serving Gateway), and a Packet Data Network Gateway (PDN Gateway, Packet Data Network Gateway). Such as figure 1 As shown in FIG. 2 , it is a schematic diagram of an architecture of a wireless evolved network in a non-roaming scenario in the prior art. Among them, MME has functions such as Network-Attached Storage (NAS, Network-Attached Storage) and NAS signaling encryption, roaming, tracking, etc., assigns temporary user IDs, security functions, etc., and it corresponds to the current Universal Mobile Telecommunications System (Universal Mobile Telecommunications ...
