Abstract
Systems, methods, apparatuses, and computer program products for partial failure handling of bearer mapping in dual connectivity are provided. One method includes, during a secondary evolved node B (SeNB) addition procedure, providing a target SeNB with an indication of SeNB change together with information on bearers that were served by a source SeNB. The method may further include receiving, by a master evolved node B (MeNB), bearer mapping for failed bearers from the target SeNB, and providing the source SeNB with the bearer mapping for the failed bearers.
Claims26
A method, comprising:
- during a secondary evolved node B (SeNB) addition procedure, providing a target SeNB with an indication of SeNB change together with information on bearers that were served by a source SeNB;
- receiving, by a master evolved node B (MeNB), bearer mapping for failed bearers from the target SeNB;
- and
- providing the source SeNB with the bearer mapping for the failed bearers.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to
- during a secondary evolved node B (SeNB) addition procedure, provide a target SeNB with an indication of SeNB change together with information on bearers that were served by a source SeNB;
- receive bearer mapping for failed bearers from the target SeNB;
- and
- provide the source SeNB with the bearer mapping for the failed bearers.
A computer program, embodied on a non-transitory computer readable medium, the computer program configured to control a processor to perform a process, comprising:
- during a secondary evolved node B (SeNB) addition procedure, providing a target SeNB with an indication of SeNB change together with information on bearers that were served by a source SeNB;
- receiving bearer mapping for failed bearers from the target SeNB;
- and
- providing the source SeNB with the bearer mapping for the failed bearers.
A method, comprising:
- receiving, during a secondary evolved node B (SeNB) addition procedure, an indication of SeNB change together with information on bearers that were served by a source SeNB;
- and
- sending bearer mapping for failed bearers to a master evolved node B (MeNB) and configuration information of successfully accepted bearers by a target SeNB.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to
- receive, during a secondary evolved node B (SeNB) addition procedure, an indication of SeNB change together with information on bearers that were served by a source SeNB;
- and
- send bearer mapping for failed bearers to a master evolved node B (MeNB) and configuration information of successfully accepted bearers by the apparatus.
A computer program, embodied on a non-transitory computer readable medium, the computer program configured to control a processor to perform a process, comprising:
- receiving, during a secondary evolved node B (SeNB) addition procedure, an indication of SeNB change together with information on bearers that were served by a source SeNB;
- and
- sending bearer mapping for failed bearers to a master evolved node B (MeNB) and configuration information of successfully accepted bearers by a target SeNB.
