[0023] However, the shortcoming of the above-mentioned reporting process is that when many UEs in the network search for a new access network, multiple UEs will simultaneously send a new access network announcement to ANDSF, causing ANDSF to process a large number of and Repeated grouping information causes ANDSF overload problem

Embodiment 1
[0057] Embodiment 1 is an embodiment in which the ANDSF sends an indication to the UE, notifying the UE to report if it finds a new access network.
[0058] Figure 6 It is a flow chart of the method for controlling UE to report network discovery in the first preferred embodiment of the present invention, as shown in Figure 6 As shown, it specifically includes the following steps:
[0059] 602: UE_A accesses the P-GW through the 3GPP IP access network, and accesses the EPC system;
[0060] 604: UE_A discovers ANDSF;
[0061] 606: UE_A sends a network access request message to ANDSF, and the message carries UE_A capability information and UE_A location information.
[0062] 608: ANDSF sends an access network update indication to UE_A, notifying UE_A that if a new non-3GPP network is found at the current location, it needs to report access network update information to ANDSF.
[0063] 610: The ANDSF sends a network access request response message to UE_A according to the lo...
Embodiment 2
[0070] Embodiment 2 is an embodiment in which the ANDSF carries an access network update indication in the access network request response message, thereby sending an indication to the UE, notifying the UE to report if it finds a new access network.
[0071] Figure 7 It is a flow chart of the method for controlling UE to report network discovery in the second preferred embodiment of the present invention, as shown in Figure 7 As shown, it specifically includes the following steps:
[0072] 702: UE_A accesses the P-GW through the 3GPP IP access network, and accesses the EPC system;
[0073] 704: UE_A discovers ANDSF;
[0074] 706: UE_A sends a network access request message to ANDSF, and the message carries UE A capability information and UE_A location information.
[0075] 708: ANDSF sends a network access request response message to UE_A according to the location information reported by UE_A, the message not only carries the access network information available at the cu...

Abstract
The invention discloses a method and a device for controlling user equipment to report network discovery. The method comprises that: an ANDSF transmits an access network updating instruction to the pre-selected user equipment (UE), wherein the access network updating instruction is used for informing the user equipment of reporting access network updating information to the ANDSF when the user equipment discovers a new access network. The method has the advantage of solving the problem of the overload of the ANDSF because a plurality of UE in the network transmits new access network information to the ANDSF at the same time when searching the new access network and then the ANDSF needs to process a large amount of repeated packet information in a short time, and further achieving the effect of enabling the ANDSF to control the UE to actively report the new access network.
Description
technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for controlling user equipment (User Equipment, UE for short) to report network discovery. Background technique [0002] The Evolved Packet System (EPS) of the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) is composed of the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN), Mobility Management Entity (MME for short), Serving Gateway (S-GW for short), Packet Data Network Gateway (P-GW or PDN GW for short), home user It consists of a Home Subscriber Server (HSS for short), a Policy and Charging Rules Function (Policy and ChargingRules Function, PCRF for short) and other supporting nodes. [0003] figure 1 It is a schematic diagram of the EPS system and the access network architecture. Such as figure 1 As shown, the EP...
