Abstract
The present invention provides a method and system for indicating data offload, and a traffic offload network element, the method comprises: when a radio bearer is established or modified, a mobility management unit of a core network notifies a traffic offload network element of the bearer type of the bearer to determine whether to start the data offload. Through the present invention, the judgment operation of the core network is simplified. In addition, under the situation that the core network side determines whether to start local access function, the traffic offload network element also can correctly start an offload policy.
Claims17
A method for indicating data offload, comprising:
- when a radio bearer is established or modified, a mobility management unit of a core network notifies a traffic offload network element of the bearer type of the bearer to determine whether to start the data offload;
- wherein the bearer type is configured to indicate whether the bearer is applied in local access.
A traffic offload network element, comprising:
- a hardware processor, configured to execute modules on a memory, the modules comprising:
- a receiving module, configured to receive a notification from a mobility management unit of a core network, wherein the notification carries the bearer type of a bearer to be established or modified;
- and an implementing module, configured to determine whether to start data offload according to the bearer type;
- wherein the traffic offload network element is configured to start an offload policy for a bearer which is applied in local access to perform data offload and accomplish local access;
- and the traffic offload network element is further configured to transmit data on a bearer which is not applied in local access to the core network.
A system for indicating data offload, comprising:
- a mobility management unit, configured to notify a bearer type of the bearer when a radio bearer is established or modified;
- and
- a traffic offload network element, configured to receive a notification transmitted by the mobility management unit and determine whether to start data offload according to the bearer type;
- wherein the mobility management unit determines to provide local access function to a user according to the situation of subscription of the user or the situation of network load.
