Problems solved by technology

In deployment scenarios such as enterprises and campuses, the data distribution gateway is usually deployed separately. At present, the existing technology cannot guarantee that the data distribution gateway can perceive the current user status of the user, let alone perceive the change of the user status. Affects the selection of the data distribution gateway for opening the extended tunnel

Embodiment 1

[0044] Method embodiment one: if image 3 As shown, the process of this method embodiment includes the following steps:

[0045] Step 301, the mobility management unit sends an air interface connection management message to the network element on the radio side.

[0046] Here, since the mobility management unit needs to change the user in the connected state to the idle state in scenarios such as user subscription change and signaling process end, it needs to send an air interface connection management message to the wireless side network element to indicate the release of the air interface connection. The air interface connection management message may be an S1 or Iu interface release message according to the specific access network.

[0047] Here, the wireless side network elements in this document include but are not limited to macro base stations, femto base stations, and femto base station gateways, which will not be described in detail.

[0048] Step 302, monitor the c...

Embodiment 3

[0066] Method embodiment three: as Figure 5 As shown, the process of this method embodiment includes the following steps:

[0067] Step 501, the mobility management unit sends a session establishment request message to the core network gateway.

[0068] Here, when the mobility management unit receives the user's PDN connection establishment request, it judges whether to enable the local access function for the user according to the requested APN or request type. If it is judged to be yes, then select the core network gateway according to the APN, select the data distribution gateway according to the user's current location, and decide to establish a core network PDN connection and an extension tunnel for the user. The mobility management unit sends the control plane TEID of the mobility management unit and the address of the data distribution gateway selected by the mobility management unit to the core network gateway through a session establishment request message.

Abstract

The invention discloses a method for notifying a user state change. When a wireless side network element monitors a user state change, it notifies the data distribution gateway of the user state change; or, when a core network element monitors a user state change, it notifies the user state change. The change of status is notified to the data distribution gateway. The invention also discloses a notification system for user status change. The notification unit in the system is used to notify the data distribution gateway of the user status change when the network element on the wireless side monitors the user status change; or, the network element monitoring of the core network When the user status changes, the data distribution gateway is notified of the user status change. The method and system of the present invention can ensure that the data distribution gateway can sense the current user status of the user in time, thereby facilitating the data distribution gateway to realize the selection of opening the extended tunnel.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for notifying user state changes when a local access function is enabled. Background technique [0002] With the continuous improvement of the air interface rate and the increase of data users, the amount of user data will show explosive growth in the future, which will inevitably have an impact on the existing core network network, and the existing core network elements will have to be expanded. To provide users with satisfactory service. Considering that most of the increased data is caused by Internet services, mobile operators hope to offload local Internet data without changing the existing network, so as to avoid the impact of large amounts of data on the core network and meet user needs. The concept of local access functionality. [0003] The introduction of a home base station (HNB, HomeNodeB) expands the application range of local access. Femtoc...
