Abstract:
1. A multi-network access control method, comprising: receiving by a User Equipment (UE) wherein the UE is multi-access-enabled, multi-access indication information sent by an access node, wherein the multi-access indication information indicates whether a data gateway supports a multi-access function, wherein the multi-access function comprises a function which enables a first set of services being visited by the UE through the data gateway via a non-3GPP access network while a second set of services being visited by the UE through the data gateway via a 3GPP access network; determining by the UE, whether the data gateway supports the multi-access function according to the received multi-access indication information sent by the access node; and if so, based on the received multi-access indication information, while the UE visiting at least two services through the data gateway via the non-3GPP access network, initiating by the UE, an access connectivity establishment to access the 3GPP access network in order to switch a part of the at least two services to the 3G access network to be visited through the data gateway while a remaining part of the at least two services is retained in the non-3GPP access network and visited through the data gateway.
