Patent ID: 8027314

Claim:
A method for transmitting Aggregate Maximum Bit Rate (AMBR) parameter during a handover process of a UE from a first network to a second network, the method comprising: acquiring, by a second network mobility management network element, a first AMBR of the UE; transmitting, by the second network mobility management network element, the acquired first AMBR to a second network access network and/or a user plane network element; and wherein acquiring the first AMBR of the UE comprises any one of: (a) default AMBR configured in the second network mobility management network element is used as the first AMBR of the UE; (b) the second network mobility management network element acquires MBR parameter values transmitted by the UE from the first network, and accumulates the acquired MBR parameter values as the first AMBR of the UE; and (c) the second network mobility management network element acquires the MBR parameter values transmitted by the UE from the first network, and selects the maximum value as the first AMBR of the UE.
