Abstract

A method for waking up one or more sleeping small cell base stations in a wireless communication system for serving a user equipment is described. The wireless communication system includes a plurality of small cell base stations and one or more macro base stations. A wake up signal configuration is received at a user equipment, and a wake up signal configured in accordance with the received wake up signal configuration is transmitted by the user equipment.

First claim

1 . A method of allocating by a virtualized resource management engine at least one virtual resource to a physical and/or software resource from a plurality of physical and/or software resources comprising the steps of:
obtaining information used to identify a first tenant requesting said at least one virtual resource, obtaining affinity information as a parameter of a resource allocation request, specifying whether or not said requested virtual resource may be collocated on the same physical and/or software resource with one or more virtual resources of another tenant different from said first tenant; allocating the at least one virtual resource based on the affinity information.

2 . The method according to claim 1 including a step to obtain information related to the current allocation of virtual resources to the plurality of physical and software resources.

3 . The method according to claim 1 , wherein said virtualized resource management engine is part of an entity responsible for the virtualized infrastructure management of virtual, physical, and software resources in a data center or cloud infrastructure.

4 . The method according to claim 1 , wherein a signaling entity of the information used to identify a first tenant and the affinity information is an entity responsible for the management of virtual network functions.

5 . The method according to claim 1 , wherein signaling is forwarded through an entity responsible for orchestration of resources and virtual network functions.

6 . The method according to claim 1 , including an intermediate step to discover the affinity information based on information received to identify the first tenant.

7 . The method according to claim 6 , wherein:
the signaling entity of the information used to identify the first tenant is an entity responsible for the management of virtual network functions, discovery of the affinity information based on the information used to identify the first tenant is performed by an entity responsible for the orchestration of resources and virtual network functions, and signaling of information used to identify the first tenant and the affinity information is performed by an entity responsible for orchestration of resources and virtual network functions.

8 . The method according to claim 1 , wherein the affinity information is part of a policy, and the affinity information is signaled as part of the setup process of said policy.

9 . The method according to claim 1 ,
wherein the process of allocating said at least one virtual resource to a physical and/or software resource from a plurality of physical and/or software resources is part of management operations, wherein management operations preferably include the first instantiation of a virtualized deployment, or the full or partial scaling out, migration or healing of virtualized resources of an existing virtualized deployment.

10 . The method according to claim 1 , wherein the at least one virtual resource is a virtual machine VM to run on a hypervisor or a virtual application container to run on an operating system, or a virtual disk drive for storage.

11 . The method according to claim 1 , wherein the allocation of virtual resources is provided for a virtualized deployment, wherein the virtualized deployment is a virtual network function VNF.

12 . The method according to claim 1 , wherein the affinity information can take multiple values to cover different allocation cases, preferably including one or more of anti-affinity to specific tenants, affinity to specific tenants, affinity to virtual resources which are compute, storage or network intensive.

13 . An apparatus for allocating by a virtualized resource management engine at least one virtual resource to a physical and/or software resource from a plurality of physical and/or software resources comprising:
a module for obtaining information used to identify a first tenant requesting said at least one virtual resource, a module for obtaining affinity information as a parameter of a resource allocation request, specifying whether or not said requested virtual resource may be collocated on the same physical and/or software resource with one or more virtual resources of another tenant different from said first tenant; a module designed to allocate the at least one virtual resource based on the affinity information.

14 . A non-transitory storage medium storing a computer program comprising a computer program code, which, when being executed on a computer, enables said computer to carry out a method of allocating by a virtualized resource management engine at least one virtual resource to a physical and/or software resource from a plurality of physical and/or software resources, the method comprising the steps of:
obtaining information used to identify a first tenant requesting said at least one virtual resource; obtaining affinity information as a parameter of a resource allocation request, specifying whether or not said requested virtual resource may be collocated on the same physical and/or software resource with one or more virtual resources of another tenant different from said first tenant; and allocating the at least one virtual resource based on the affinity information.
