Abstract
The embodiments herein relates to a method in a target Mobility Management Entity, MME, for allocating bearers in a target network, which target MME is comprised in the target network and which target network comprises a first number of existing bearers. When a second number of required bearers is larger than the first number of existing bearers in the target network, the target MME transmits an allocation request message to a target base station. The allocation request message comprises a request for allocation of the first number of existing bearers and a request for allocation of a third number of extra bearers in the target network.
Claims58
A method in a target Mobility Management Entity, MME, for allocating bearers in a target network, which target MME is comprised in the target network and which target network comprises a first number of existing bearers, the method comprising:
- determining whether a second number of required bearers is larger than the first number of existing bearers in the target network;
- and
- when it is determined that the second number of required bearers is larger than the first number of existing bearers in the target network, transmitting an allocation request message to a target base station, which allocation request message comprises a request for allocation of the first number of existing bearers and a request for allocation of a third number of extra bearers in the target network.
A method in a target base station for allocating bearers in a target network, which target base station is comprised in the target network and which target network comprises a first number of existing bearers, the method comprising:
- when a second number of required bearers is larger than the first number of existing bearers in the target network, receiving an allocation request message from a target Mobility Management Entity, MME, which allocation request message comprises a request for allocation of the first number of existing bearers and a request for allocation of a third number of extra bearers in the target network;
- allocating the first number of existing bearers;
- and
- allocating the third number of extra bearers.
A method in a source network node for allocating bearers in a target network, which source network node is comprised in the source network and which target network comprises a first number of existing bearers, the method comprising:
- determining a second number of required bearers in the target network for handover from the source network to the target network.
A target Mobility Management Entity, MME, for allocating bearers in a target network, which target MME is comprised in the target network and which target network comprises a first number of existing bearers, the target MME comprises:
- a transmitter configured to, when a second number of required bearers is larger than the first number of existing bearers in the target network, transmit an allocation request message to a target base station, which allocation request message comprises a request for allocation of the first number of existing bearers and a request for allocation of a third number of extra bearers in the target network.
A target base station for allocating bearers in a target network, which target base station is comprised in the target network and which target network comprises a first number of existing bearers, the target base station comprising:
- a receiver configured to, when a second number of required bearers is larger than the first number of existing bearers in the target network, receive an allocation request message from a target Mobility Management Entity, MME, which allocation request message comprises a request for allocation of the first number of existing bearers and a request for allocation of a third number of extra bearers in the target network;
- and
- a processor configured to:
- allocate the first number of existing bearers;
- and to
- allocate the third number of extra bearers.
A source network node for allocating bearers in a target network, which source network node is comprised in the source network and which target network comprises a first number of existing bearers, the source network node comprising:
- a processor configured to determine a second number of required bearers in the target network for handover from the source network to the target network.
