Embodiment 1

[0060] Embodiment 1 of the present invention provides a method for notifying congestion information, such as Figure 7 As shown, the method includes the following steps:

[0061] In step 701, an ANDSF entity obtains congestion information of an access network.

[0062] Method 1: The ANDSF entity obtains congestion information from information interacted with the network. Specifically, in the information exchanged between the ANDSF entity and the network, the network can provide the ANDSF entity with congestion information of the access network, so the ANDSF entity can obtain the congestion information of the access network.

[0063] Method 2: The ANDSF entity obtains the congestion information through the operator's configuration. Specifically, after learning the congestion information, the operator can configure the congestion information on the ANDSF entity, so that the ANDSF entity can obtain the congestion information.

[0064] In the embodiment of the present invention...

Embodiment 2

[0086] Based on the same inventive concept as the above method, an access network discovery and selection function ANDSF entity is also provided in the embodiment of the present invention, such as Figure 10 As shown, the ANDSF entities include:

[0087] Obtaining module 11, configured to obtain congestion information of the access network.

[0088] The obtaining module 11 is specifically configured to obtain the congestion information from information interacted with the network; or, obtain the congestion information through operator configuration.

[0089] The sending module 12 is configured to notify the user equipment of the congestion information through an ANDSF policy message. An information element indicating congestion information is set in the ANDSF policy message, and the information element is used to carry the congestion information; and different values ​​of the information element indicate different congestion degrees.

[0090] In the embodiment of the present...

Embodiment 3

[0094] Based on the same inventive concept as the above method, an embodiment of the present invention also provides a user equipment, such as Figure 11 As shown, the user equipment includes:

[0095] The receiving module 21 is configured to receive the congestion information of the access network notified by the ANDSF entity of the access network discovery and selection function through an ANDSF policy message.

[0096] The receiving module 21 is specifically configured to receive the changed congestion information notified by the ANDSF entity through the ANDSF policy message when the congestion information of the access network changes; or, when sending a policy request message to the ANDSF entity Afterwards, the current congestion information notified by the ANDSF entity through the ANDSF policy message is received.

[0097] The obtaining module 22 is configured to obtain the congestion information from the ANDSF policy message.

[0098] In the embodiment of the present ...

Abstract

The invention discloses a congestion information notification method and congestion information notification equipment. The method comprises that: an access network discovery and selection function (ANDSF) entity obtains the congestion information of an access network; and the ANDSF entity notifies the congestion information to user equipment by an ANDSF policy message. In the embodiment of the invention, the congestion information of the access network is carried in the ANDSF policy message, so that the user equipment (UE) can acquire the congestion conditions of different access networks from the ANDSF policy message and further select a wireless access network to be used according to the congestion conditions, and the condition that the UE unknowing the congestion conditions of the network cannot access the network can be avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for notifying congestion information. Background technique [0002] In an EPS (Evolved Packet System, evolved packet system) network that supports multiple access, EPS supports 3GPP (The 3rd Generation Partnership Project, Third Generation Partnership Project) access and non-3GPP access and other wireless access Ways, such as UTRAN (Universal Terrestrial Radio Access Network, Universal Terrestrial Radio Access Network), E-UTRAN (Evolved UTRAN, Evolved Universal Terrestrial Radio Access Network), CDMA2000 (Code Division Multiple Access, Code Division Multiple Access), WLAN (Wireless Local Access Network, wireless local area network), etc. [0003] Such as figure 1 As shown, it is a schematic diagram of a multi-access EPS network. When UE (User Equipment, user equipment) accesses the core network through 3GPP access technology, the core network ...
