Abstract
A method for gateway relocation, an MME and a DeNB are disclosed. The method includes: in a process of an MRN performing handover of the DeNB, the MME of the MRN judging whether it is required to execute a relocation of a gateway serving the MRN according to the current location of the MRN.
Claims32
A method for gateway relocation, comprising:
- in a process of a mobile relay node, MRN, performing handover of a donor evolved Node B, DeNB, a mobility management entity, MME, of the MRN judging whether it is required to execute a relocation of a gateway serving the MRN according to a current location of the MRN.
A method for gateway relocation, comprising:
- in a process of a mobile relay node, MRN, performing handover of a donor evolved Node B, DeNB, a mobility management entity, MME, of the MRN receiving relocation judgment indication information, and judging whether it is required to execute a relocation of a gateway serving the MRN according to the relocation judgment indication information;
- wherein, the relocation judgment indication information is sent to the MME after a source DeNB or a target DeNB of the MRN judges whether it is required to execute the relocation of the gateway serving the MRN according to relocation judgment auxiliary information;
- or the relocation judgment indication information is sent to the MME after a target DeNB of the MRN judges whether it is required to execute the relocation of the gateway serving the MRN according to configuration information.
A mobility management entity, comprising:
- a location determination unit and a first judgment unit, wherein:
- the location determination unit is configured to:
- in a process of a mobile relay node, MRN, performing handover of a donor evolved Node B, DeNB, determine a current location of the MRN;
- and
- the first judgment unit is configured to:
- judge whether it is required to execute a relocation of a gateway serving the MRN according to the current location of the MRN.

A mobility management entity, comprising:
- a receiving unit and a relocation judgment unit, wherein:
- the receiving unit is configured to:
- in a process of a mobile relay node, MRN, performing handover of a donor evolved Node B, DeNB, receive relocation judgment indication information;
- and
- the relocation judgment unit is configured to:
- judge whether it is required to execute a relocation of a gateway serving the MRN according to the relocation judgment indication information;
- wherein, the relocation judgment indication information is sent to the receiving unit after a source DeNB or a target DeNB of the MRN judges whether it is required to execute the relocation of the gateway serving the MRN according to relocation judgment auxiliary information;
- or the relocation judgment indication information is sent to the receiving unit after a target DeNB of the MRN judges whether it is required to execute the relocation of the gateway serving the MRN according to configuration information.

A donor evolved Node B, comprising:
- a judgment unit and a sending unit, wherein:
- the judgment unit is configured to:
- in a process of a mobile relay node, MRN, performing handover of a donor evolved Node B, DeNB, judge whether it is required to execute a relocation of a gateway serving the MRN according to relocation judgment auxiliary information;
- or, judge whether it is required to execute a relocation of a gateway serving the MRN according to configuration information;
- and
- the sending unit is configured to:
- send relocation judgment indication information to a mobility management entity, MME, of the MRN.
