Abstract

In a radio access network (24) wherein a protocol stack is split between anchor processor circuitry (40) and distributed processor circuitry (42). The anchor processor circuitry (40) is configured to perform high layer radio access network node operations (50) for a connection with a wireless terminal. The distributed processor circuitry (42) is configured to perform low layer radio access network node operations (52) for the connection with the wireless terminal (30) and to utilize the context as used by the anchor processor circuitry (40). The anchor processor circuitry (40) is configured to provide a first endpoint for a tunnel (60) through which the connection is carried over a packet network (48) to the distributed processor circuitry (42); the distributed processor circuitry (42) is configured to provide a second endpoint for the tunnel (60). Transceiver circuitry (44) transmits and receives packets comprising the connection over a radio interface with the wireless terminal (30).

Description

technical field [0001] The technology relates to wireless communications, and in particular, to radio access network architecture and operation. Background technique [0002] A radio access network typically resides between wireless devices, such as user equipment (UE), mobile phones, mobile stations, or any other device with wireless terminals, and the core network. Examples of radio access network types include: GRAM, the GSM radio access network; GERAN, including the EDGE packet radio service; UTRAN, the UMTS radio access network; and E-UTRAN, including the Long Term Evolution. [0003] A radio access network may include one or more access nodes, such as base station nodes, that facilitate wireless communications or otherwise provide an interface between wireless terminals and a telecommunications system. Non-limiting examples of base stations may include Node B (“NB”), enhanced Node B (“eNB”), home eNB (“HeNB”), depending on the type of radio access technology , gNB (f...
