Apparatuses and methods in a communication system are provided. The solution comprises operating a radio access network, where the radio access network comprises two or more resource tiers, each tier having different latency/timing requirements. The resource allocation for the radio access network is realised () with two or more control loops, where each control loop is configured to allocate resources with different latency requirements, and control resources between the tiers. Resources of the inmost tier are controlled () by an inmost control loop with lowest latency resource allocation, and resources of the outer tiers are controlled () by one or more outer control loops for less latency critical resource allocation, each outer control loop having less critical latency requirement compared to loops closer to the inmost loop.

A method for managing a virtual radio access network which serves a radio cell is provided. The method includes selecting, based on a radio access technology of the radio cell, a construction scheme for the virtual radio access network in a repository. Further, the method includes querying, from the repository, at least one software component associated to the construction scheme. The software component represents a virtualized network function of the virtual radio access network. The method additionally includes setting up, using the software component, the virtualized network function on a runtime platform according to the construction scheme.

Not Mobile IP (NMIP) comprises methods for implementing macro-mobility in an IP network, wherein macro-mobility means the ability of a node to change its network-layer, e.g., IP, address without disturbing existing transport-layer and application-layer sessions, e.g., conversations. When two NMIP nodes establish a new NMIP session, they exchange pseudo-random numbers, or nonces, and store the nonces in a session table. When a first node changes its IP address, the first node sends to the second node an address-update message that contains the new IP address and the first node's nonce. If the received nonce matches a nonce in the session table, then the second node updates its protocol control blocks with the new IP address, and sends an address-update reply message to the first node. Internet Protocol Security (IPsec) can be used to secure or replace the exchange of nonces.

A method and an apparatus are provided for enabling a wireless communication over a network in response to an indication of an emergency. The method comprises causing a base station to provide a wireless backhaul link in an uplink frequency band for further sending a call over the network in response to the call associated with the emergency. Reconfiguration enables turning a base station or base station router into a high power terminal. In this way, emergency calls may be completed over a network having at least one malfunctioning backhaul communications link in a network backbone.
