Abstract
A system for configuring a UE-AMBR includes a MME to send the UE-AMBR to an eNB covering the serving cell of the UE, the eNB covering the serving cell of the UE establishes a radio access bearer of the UE on at least one secondary cell. The MME sends an AMBR of the UE in the primary eNB covering the serving cell of the UE and an AMBR of the UE in a secondary eNB to the primary eNB. The primary eNB sends the AMBR of the secondary eNB to the corresponding secondary eNB. The technical solutions of the present disclosure can make total rate of all non-GBR services of the UE be not larger than the UE-AMBR when the UE has multiple S1 bearers or one S1 bearer.
Claims16
A method, by a first base station, for configuring an aggregate maximum bit rate (AMBR) of a user equipment (UE) (UE-AMBR), the method comprising:
- receiving, from a mobility management entity (MME), an initial UE context setup message including a total UE-AMBR;
- sending, to a second base station, a request message including a second UE-AMBR, wherein the total UE-AMBR is split into a first UE AMBR and the second UE-AMBR which are enforced by the first base station and the second base station respectively, for dual connectivity;
- and
- receiving, from the second base station, a response message in response to the request message, and
- wherein the total UE-AMBR is higher than the second UE-AMBR.
A method, by a second base station, for configuring an aggregate maximum bit rate (AMBR) of a user equipment (UE) (UE-AMBR), the method comprising:
- receiving, from a first base station, a request message including a second UE-AMBR that is used for a second base station to limit resource allocation to the UE for dual connectivity;
- and
- sending, to the first base station, a response message in response to the request message, and
- wherein the second UE-AMBR is split from a total UE-AMBR included in an initial UE context setup message that is transmitted from a mobility management entity (MME) to the first base station, and
- wherein the total UE-AMBR is higher than the second UE-AMBR.
A first base station for configuring an aggregate maximum bit rate (AMBR) of a user equipment (UE) (UE-AMBR), comprising:
- a transceiver for transmitting and receiving signals to and from a second base station and a mobility management entity (MME) and
- a controller configured to control the transceiver to:
- receive an initial UE context setup message including a total UE-AMBR from the MME,
- transmit, to the second base station, a request message including a second UE-AMBR, wherein the total UE-AMBR is split into a first UE AMBR and the second UE-AMBR which are enforced by the first base station and the second base station respectively, for dual connectivity,
- receive a response message in response to the request message from the second base station, and
- wherein the total UE-AMBR is higher than the second UE-AMBR.
A second base station for configuring an aggregate maximum bit rate (AMBR) of a user equipment (UE) (UE-AMBR), comprising:
- a transceiver for transmitting and receiving signals to and from a first base station and a mobility management entity (MME) and
- a controller configured to control the transceiver to:
- receive a request message including a second UE-AMBR that is used for a second base station to limit resource allocation to the UE for dual connectivity;
- and
- transmit, to the first base station, a response message in response to the request message, and
- wherein the second UE-AMBR is split from a total UE-AMBR included in an initial UE context setup message that is transmitted from a mobility management entity (MME) to the first base station, and
- wherein the total UE-AMBR is higher than the second UE-AMBR.
