A method and apparatus may include receiving, by a user equipment from a first access point which supports a first radio access technology, a radio-resource-control (RRC) reconfiguration message including an RRC configuration information of a second access point, after an initiation of a slave RRC at the second access point has been determined. The second access point supports a second radio access technology, and performing, by the user equipment, a random access procedure with the second access point based on the RRC reconfiguration message. The user equipment is configured to have an RRC connection with the first access point and the first access point is a master node.

Various communication systems may benefit from improved quality of service treatment in the access networks. For example, certain communication systems may benefit from a dynamic varying of the quality of service level of a data flow. A method may include detecting a requested quality of service level requirement at a new data flow or an existing data flow at a network entity. The method may also include retrieving from a table a needed parameter linked to the requested quality of service level. In addition, the method can include using the needed parameter to create a new processing instance or to update an existing processing instance at the network entity. A method may further include updating the content of the table through separate signaling.

Configurable mapping of quality of service classes

Methods, systems, and computer readable media for providing cloud visibility are disclosed. According to one method, the method includes obtaining at least one correlation profile for indicating effects of workload configurations on hardware and/or software measurements of a reference server, wherein the reference server includes components for measuring hardware and/or software performance. The method also includes configuring the reference server, wherein the reference server is one of a plurality of servers in a cloud-based environment for executing a workload, wherein each of the plurality of servers executes at least a portion of the workload. The method further includes receiving, from the reference server, measurements associated with executing at least the portion of the workload. The method also includes generating information regarding the cloud-based environment using the measurements from the reference server and the at least one correlation profile.

A method and apparatus may include determining, by a network node, that a slave radio-resource-control function is to be initiated. The slave radio-resource-control function may be performed by an access point. The method may also include transmitting a message to the access point. The message includes at least one of a request to initiate the slave radio-resource-control function and a confirmation that the slave radio-resource-control function can be initiated.

There is provided a method comprising receiving, at a control node associated with a plurality of access points of a first network (e.g. a WLAN Interworking Gateway&#x2014;WIG), information from an access point of a second network (e.g. an eNB of a LTE network), wherein the received information is useable by the control node to perform at least one association procedure (e.g. AP selection, local IP and MAC address assignment, admission control, authentication) with an access point of the first network (e.g. WLAN) on behalf of a user equipment, said user equipment being associated with the second network, performing said at least one association procedure and providing association procedure information to the access point of the second network.

There are provided measures for enabling/realizing interface functionality for RAN-WLAN radio aggregation, i.e. radio level integration/aggregation between a cellular radio access network and a wireless area network. Such measures exemplarily comprise user-plane data forwarding from a cellular radio access network over a wireless local area network to a terminal, both the cellular radio access network and the wireless local area network providing radio level connectivity for the terminal, wherein in the user-plane data forwarding user-plane data packets according to a cellular data convergence protocol are transported, at least partly, using a reliable transport protocol over the wireless local area network to the terminal, providing feedback on performance of user-plane data packets transport using the reliable transport protocol, at least partly, from the wireless local area network to the cellular radio access network, and executing flow control on the basis of the performance feedback.

There is provided a method comprising causing uplink feedback information to be transmitted via a radio interface of a first access point, wherein the uplink feedback information is associated with a protocol entity for downlink data transmission via a radio interface of a second access point only.

Method, system and apparatus

A method, apparatus, and computer program for scanning for a secondary cell are provided. According to an embodiment, an apparatus operates in a primary cell of a cellular communication system, wherein the primary cell includes a primary component carrier associated with a bandwidth. The apparatus synchronizes scanning for a candidate secondary cell to radio transmissions in the primary cell, the secondary cell including a secondary component carrier expanding bandwidth beyond the bandwidth of the primary cell.

Scanning secondary cells in cellular communications system

An apparatus defines a set of resources out of a first number of orthogonal radio resources and controls a transmitting means to simultaneously transmit a respective first radio signal for each resource on all resources of the set. A respective estimated interference is estimated on each of the resources of the set when the respective first radio signals are transmitted simultaneously. A first resource of the set is selected if the estimated interference on the first resource exceeds a first predefined level and, in the set, the first resource is replaced by a second resource of the first number of resources not having been part of the set. Each of the controlling and the estimating, the selecting, and the replacing is performed in order, respectively, for a predefined time.

Efficient co-existence method for dynamic spectrum sharing

Mechanisms for enabling distributed access control are disclosed. At least one communication channel is selected for wireless communication by a device by a selection procedure where interference impact of at least one communication channel on at least one interfered node is determined, an overall interference effect is formed, and a set of feasible communication channels is selected based on comparison of the overall interference effect to communication channel capacity. At least one communication channel can be selected from the selected set of feasible communication channels based on transmission collision information, a ratio of capacity of interfered transmissions and capacity of interference-free transmissions, usage history of the feasible communication channels, and fairness of communication channel selection. Information can be communicated to at least one device from a plurality of access nodes.
