The method includes modifying a routing rule of a load balancer of the system, the rule representing at least one parameter for communications between a client device and the first VM to specify that data from the client device destined for the first VM instance is queued, suspending processing, at the first VM instance, of pending requests from the client device, transmitting data, from the first VM instance, to the load balancer representing the state of the or each suspended request, modifying the routing rule to specify that the endpoint for a communication channel from the second VM instance is the client device, transmitting the or each suspended request to the second VM instance, and modifying the routing rule to specify transmission of data from the client device directly to the second VM instance.

A method, in a virtualized system, for balancing a load across multiple virtual machines instantiated over physical hardware of the system, including vertically scaling the capacity of respective ones of the VMs up to a physical capacity limit, L, from an initially allocated physical capacity, L, by providing access to additional resources of the physical hardware in response to an increased load causing the or each VM to reach or exceed a threshold capacity L, and horizontally scaling the capacity of the system by supplementing the multiple VMs with an additional VM instantiated using a hypervisor of the system when a predefined proportion, U, of the VMs have a capacity L.

Methods and network nodes of a wireless telecommunications system are disclosed. One method of controlling transmissions with a base station of a wireless telecommunications system comprises the steps of: determining a set of neighboring base stations, each base station in the set of neighboring base stations utilizing an identical carrier and scrambling code to support transmissions with that base station; and allocating base stations in the set of neighboring base stations different spreading codes for transmissions with those base stations. By allocating each base station in the set of base stations sharing the same carrier and scrambling code different spreading codes, interference in transmissions between the base stations can be controlled.

Network nodes and methods

A method is provided of selecting carrier frequency band of a femtocell base station that provides a femtocell and resides within a macrocell provided by a macrocell base station. The method comprises: the femtocell base station operating at the carrier frequency band of the macrocell, detecting that a user terminal connected to the macrocell base station at an carrier frequency band of the macrocell is in or close to the femtocell, and the femtocell base station switching its carrier frequency band to one not allocated to the macrocell.
