Problems solved by technology

Therefore, the processing of these two accesses is different, and the 3GPP system needs to distinguish between these two different processing methods, but there is no corresponding mechanism in the current 3GPP system to distinguish the processing
[0024] 3. The processing in the access process in the existing 3GPP system is that the UE only initiates the establishment of a default bearer, that is to say, the MME can only initiate the default bearer establishment process for one PDN GW
If the UE uses multiple PDN GWs in a non-3GPP access system, existing mechanisms cannot handle
[0025] 4. The handover between non-3GPP and 3GPP systems in the prior art is a "loosely coupled" handover, that is, the UE is disconnected from the source side system first, and completes the handover from the target side system through the access process
This switching method will cause business interruption for a relatively long time, which may lead to business interruption
How to optimize the handover between non-3GPP and 3GPP systems and reduce the time of UE service interruption, there is no corresponding mechanism to deal with it in the prior art

Embodiment 1

[0052] When the first network element on the network side sends a request to create a default bearer (or create a default packet data protocol (PDP, Packet Data Protocol) context request) to the serving gateway (Serving GW), when it carries a flag bit, it indicates that a bearer is created (or a PDP is created). Context) processing type, the Serving GW sends the Create Default Bearer Request (or Create Default PDP Context Request) to the PDN GW with a flag to indicate the processing type. After receiving the message, the PDN GW performs different processes according to the flag bits. See attached for specific process image 3 ,include:

[0053] 1. The UE accesses the Non-3GPP access network through the Non-3GPP gateway and the PDN GW.

[0054] 2. The UE initiates a handover between the non-3GPP access system and the 3GPP access system.

[0055] 3. The UE sends an attach request message to the first network element on the network side to perform a handover process from the n...

Embodiment 2

[0083] When the first network element on the network side sends a request to create a default bearer (or a request to create a default PDP context) to the Serving GW, when it carries a flag to indicate the processing type of creating a bearer (or to create a PDP context), the Serving GW sends a proxy binding update When the message is sent to the PDN GW, it carries a flag to indicate the processing type. After receiving the message, the PDN GW performs different processes according to the flag bits. See attached for specific process Figure 4 ,include:

[0084] 1. The UE accesses the Non-3GPP access network through the Non-3GPP gateway and the PDN GW.

[0085] 2. The UE initiates a handover between the non-3GPP access system and the 3GPP access system.

[0086] 3. The UE sends an attach request message to the first network element on the network side to perform a handover process from the non-3GPP system to the 3GPP system. For the SAE system, the first network element at ...

Embodiment 3

[0112] When the non-3GPP (non-3GPP) gateway network element sends the proxy binding update message to the PDN GW, it carries a flag to indicate the processing type. After receiving the message, the PDN GW performs different processes according to the flag bits. See attached for specific process Figure 5 ,include:

[0113] 1. The UE accesses the 3GPP access network through the Serving GW and the PDN GW.

[0114] 2. The UE initiates a handover between the 3GPP access system and the non-3GPP access system.

[0115] 3. The UE sends an access request message to the non-3GPP gateway network element to perform a handover process from the 3GPP system to the non-3GPP system. For the WLAN system, the non-3GPP gateway network element is EPDG (Evolved Packet Data Gateway); for the Wimax system, the non-3GPP gateway network element is ASN GW (access service network gateway, Access Service Network Gateway ); for a CDMA system, the non-3GPP gateway network element is an AGW (Access Gate...

Abstract

The embodiment of the present invention discloses a resource creation method, including: the first network element notifies the network side of the processing type of the second network element to create resources for the user equipment; The device creates and processes corresponding resources. The embodiment of the invention also discloses corresponding network equipment. Adopting the embodiment of the present invention solves the problem that in the prior art, the network side gateway network element (that is, the second network element) cannot identify different access requests (that is, the initialization access request and the access request caused by the switching of the access system), thus The problem that corresponding resources cannot be created for different access requests.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource creation method and network equipment. Background technique [0002] In order to enhance the competitiveness of future networks, 3GPP is studying a new evolved network, and its system architecture is shown in the attached figure 1 As shown, it includes the Evolved Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) Terrestrial Radio Access Network (E-UTRAN, Evolved UMTST Terrestrial Radio Access Network), which is used to realize all functions related to the wireless network of the evolution; the mobility management entity (MME, Mobility Management Entity), responsible for the mobility management of the control plane, including user context and mobility state management, assigning user temporary identity marks, etc.; serving gateway entity (Serving GW, Serving Gateway), is the user between 3GPP access systems Th...
