Abstract
When a failed connection is detected from a first radio unit (RU) to the cellular site router (CSR), activation of an existing backup cabled connection from the first RU to the CSR through a cabled connection between the first RU and a second RU of the cellular telecommunications tower may be performed. In one example, a first RU and second RU each have two physical network ports. The activation of the existing backup cabled connection from the first RU, via the second RU, to the CSR may include causing the first RU to enter from a normal operating mode into an Open Radio Access Network (O-RAN) cascade operating mode to attempt to attain network connectivity for the first RU using the second physical network port of the first RU.
Claims20
A system of a first radio unit of a cellular telecommunications tower, the system comprising:
- at least one memory that stores computer instructions;
- and
- at least one processor that executes the computer instructions to perform actions, the actions including:
- determining that a cabled connection directly between the first radio unit of the cellular telecommunications tower and a cellular site router of the cellular telecommunications tower has failed, wherein the cabled connection directly between the first radio unit and the cellular site router uses a first physical network port of the first radio unit;
- and
- in response to determining that the connection between the first radio unit and the cellular site router has failed, initiating activation of an existing backup cabled connection from the first radio unit to the cellular site router through a cabled connection between the first radio unit and a second radio unit of the cellular telecommunications tower, wherein the cabled connection between the first radio unit and a second radio unit uses a second physical network port of the first radio unit and the second radio unit also has an existing separate cabled connection directly to the cellular site router.
A method in a first radio unit of a cellular telecommunications tower, the method comprising:
- determining that a cabled connection directly between the first radio unit of the cellular telecommunications tower and a cellular site router of the cellular telecommunications tower has failed, wherein the cabled connection directly between the first radio unit and the cellular site router uses a first physical network port of the first radio unit;
- and
- in response to determining that the connection between the first radio unit and the cellular site router has failed, initiating activation of an existing backup cabled connection from the first radio unit to the cellular site router through a cabled connection between the first radio unit and a second radio unit of the cellular telecommunications tower, wherein the cabled connection between the first radio unit and a second radio unit uses a second physical network port of the first radio unit and the second radio unit also has an existing separate cabled connection directly to the cellular site router.
A non-transitory computer-readable storage medium having computer-executable instructions stored thereon that, when executed by at least one processor, cause the at least one processor to perform operations including:
- determining that a cabled connection directly between a first radio unit of a cellular telecommunications tower and a cellular site router of the cellular telecommunications tower has failed, wherein the cabled connection directly between the first radio unit and the cellular site router uses a first physical network port of the first radio unit;
- and
- in response to determining that the connection between the first radio unit and the cellular site router has failed, initiating activation of an existing backup cabled connection from the first radio unit to the cellular site router through a cabled connection between the first radio unit and a second radio unit of the cellular telecommunications tower, wherein the cabled connection between the first radio unit and a second radio unit uses a second physical network port of the first radio unit and the second radio unit also has an existing separate cabled connection directly to the cellular site router.
