Abstract
A radio access network (RAN) configured to support real-time communications over a Long-Term Evolution (LTE) connection is described herein. When a request for a data transmission is received and a real-time communication session over the LTE connection is established, the RAN utilizes the LTE connection, not a New Radio (NR) connection, for the data transmission. When a request for a further real-time communication is received and there is an active data transmission session over the NR connection, the RAN performs at least one of ceasing to allocate traffic to the NR connection for downlink or reconfiguring the data transmission session to send data over the LTE connection.
Claims20
A radio access network, comprising:
- a processor;
- a Long-Term Evolution (LTE) transceiver coupled to the processor and configured to send and receive at least real-time communications and data transmissions;
- a new radio (NR) transceiver coupled to the process and configured to send and receive at least data transmissions;
- and
- memory coupled to the processor and storing instructions that, when executed by the processor, cause the radio access network to perform operations comprising:
- receiving a request for a real-time communication session;
- upon receiving the request, determining whether a data transmission session over a new radio (NR) connection is active;
- and
- when the data transmission session is active, ceasing to allocate traffic to the NR connection for downlink for a threshold amount of time.
A method comprising:
- receiving, by a radio access network (RAN), a request for a real-time communication session;
- upon receiving the request, determining, by the RAN, whether a data transmission session over a new radio (NR) connection is active;
- and
- when the data transmission session is active, ceasing, by the RAN, to allocate traffic to the NR connection for downlink for a threshold amount of time.
A non-transitory computer-readable medium having programming instructions stored thereon that, when executed by a computing device of a radio access network cause the radio access network to perform operations comprising:
- receiving, by a radio access network (RAN), a request to for a real-time communication session;
- upon receiving the request, determining, by the RAN, whether a data transmission session over a new radio (NR) connection is active;
- and
- when the data transmission session is active, ceasing, by the RAN, to allocate traffic to the NR connection for downlink for a threshold amount of time.
