Abstract
In general, the current subject matter relates to clock selection in a fronthaul network. In some implementations, clock selection in a fronthaul network can include selecting one distributed unit (DU) from among a plurality of DUs communicatively coupled to a radio unit (RU) to serve as a primary clock for a communication system including the plurality of DUs, the RU, and a service management and orchestration (SMO), and transmitting a request to the RU that triggers the RU to select one of the DUs to become the primary clock. The SMO can be communicatively coupled to the RU and the plurality of DUs.
Claims20
A computer-implemented method, comprising:
- determining to switch a primary clock for a communication system from one distributed unit (DU), from among a plurality of DUs communicatively coupled to a radio unit (RU), the communication system including the plurality of DUs, the RU, and a service management and orchestration (SMO);
- and
- based on the determining, transmitting a request that triggers the RU to select another DU of the plurality of DUs to become the primary clock,
- wherein the SMO is communicatively coupled to the RU and the plurality of DUs, and
- wherein the SMO determines to switch the primary clock for the communication system.
An apparatus, comprising:
- at least one processor, and
- at least one non-transitory storage media storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
- determining to switch a primary clock for a communication system from one distributed unit (DU), from among a plurality of DUs communicatively coupled to a radio unit (RU), the communication system including the plurality of DUs, the RU, and a service management and orchestration (SMO);
- and
- based on the determining, transmitting a request that triggers the RU to select another DU of the plurality of DUs to become the primary clock,
- wherein the SMO is communicatively coupled to the RU and the plurality of DUs, and
- wherein the SMO determines to switch the primary clock for the communication system.
At least one non-transitory storage media storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:
- determining to switch a primary clock for a communication system from one distributed unit (DU), from among a plurality of DUs communicatively coupled to a radio unit (RU), the communication system including the plurality of DUs, the RU, and a service management and orchestration (SMO);
- and
- based on the determining, transmitting a request that triggers the RU to select another DU of the plurality of DUs to become the primary clock,
- wherein the SMO is communicatively coupled to the RU and the plurality of DUs, and
- wherein the SMO determines to switch the primary clock for the communication system.
