Methods, a local mobility anchor (LMA) and a mobility access gateway (MAG) are provided for supporting multiple connections of a user equipment (UE) towards a given access point. As a UE connection is set up, the MAG provides a unique identifier (UID) for the connection and sends it toward the LMA. The LMA stores the UID along with an identity of the UE, an address of the MAG and an access point name in a binding cache entry. As the UE sets up an additional connection towards the same access point, the MAG provides another UID, which is also sent to the LMA. The LMA stores a distinct binding cache entry for that distinct UID. If a given connection is released or handed over to another MAG, a UID corresponding to the given connection is used at the LMA to release or update the proper binding cache entry.
