摘要： A method of allocating user plane nodes to a connection being established across a packet core network. The method comprises maintaining at a Domain Name System, DNS, server, one or more DNS resource records for each available user plane node or group of neighboring user plane nodes, a DNS resource record containing a measure of a route quality or cost between the associated user plane node(s) or group(s) and each of one or more further user plane nodes or further groups of neighboring user plane nodes of the packet core network to which said associated user plane node(s) or groups is(are) connected. A connection establishment request is processed at a mobility management control entity within the packet core network, with a DNS query being sent to a DNS server, the query containing one or more user plane node selection criteria. The query is received at the DNS server and, on the basis of the or each criterion, one or more DNS resource records satisfying the criteria/criterion identified. At least said measure of route quality or cost of the identified DNS resource record(s) is returned to said mobility management control entity. The measure(s) of route quality or cost of the identified DNS resource record(s) is received at the mobility management control entity, and the measure(s) used to allocate a user plane node or nodes to said connection.

摘要： The present invention relates to methods and arrangements in a wireless communication system that enable a load balancing procedure in a network with HeNB GWs. The problem of the ineffective conventional load balancing procedure when used in a network with HeNB GWs, is addressed by a solution where the HeNB includes (510) an explicit indication of the reason for radio link establishment (load balancing establishment cause) in the S1AP INITIAL UE MESSAGE message (511) used to establish the S1 signaling connection associated with a user equipment to an MME, so that the HeNB GW (550) can perform an accurate MME selection based on the knowledge that the establishment is due to load balancing, i.e. an MME selection that realizes the required inter-MME load balancing.

摘要： A method in a access control node for selecting of a local gateway co-located with or near a home node is provided. The access control node receives (201) a connectivity request from a user equipment. The user equipment requests a local or remote connection to the home node. The access control node obtains (202) an access point name of the home node. The access control node selects the local gateway co-located with or near the home node by the action of sending (203) a domain name system query to a home node gateway associated with the home node, by addressing a domain name system server. The query comprises a request for an IP address of the local gateway that is associated with the obtained access point name. The access control node selects the local gateway co-located with or near the home node by the further action of receiving (204) a response from the domain name system server. The response comprising the requested IP address of the local gateway.

摘要： The basic idea of the present invention is to let the base station enter a low-power, low-radiation cycle, the so called “sleep mode”, when there are no UEs using it and to introduce methods to “wake up” the base station from this state when there is a UE in the vicinity which is allowed to access the base station and which may need it on short notice.

摘要： The present invention relates to methods and arrangements for providing macro diversity, also referred to as diversity handover, DHO, related instructions to a node, e.g. a Node B, that is a part of a DHO connection in a mobile telecommunication network wherein the macro diversity functionality is distributed to a Radio Network Controller, RNC, and its connected Node Bs in said network. The method comprises the steps of: including in a signaling message one or more transport layer addresses and one or more transport bearer reference parameters in order to direct one or more data flows of the DHO connection, and sending said signaling message to said node.

摘要： The present invention relates to an arrangement, a communication network node and a method of saving radio resources during handover in a communication network system comprising a plurality of communication network nodes (15a, 15b, 15c) communicating with one or more user equipments (18). Each network node (15a, 15b, 15c) is serving at least one cell (19) through and in which the user equipments (18) are moving. The method and arrangement is based on: collection of long term handover statistics (1); selective triggering of Multiple Cell Preparation (2); definition of a Secondary Target Cell List (3); exclusion from the Secondary Target Cell List of cells rarely used (4); preparation of the cells on the Secondary Target Cell List for handover (5).

摘要： The invention relates to a method in a target radio base station (14) for enabling a handover of a connection to a user equipment (13) from a source cell (12) to a target cell (11) associated with a target cell identity. The source cell (12) is served by a source radio base station (15) and the target cell (11) is served by the target radio base station (14). The target radio base station (14) and the source radio base station (15) are comprised in a radio communications network (100) and the target radio base station (14) is adapted to be connected to a gateway node (16) associated with a network node identity. The gateway node (16) is acting as a proxy for the target radio base station (14) towards a core network (17) and towards the source radio base station (15). The target radio base station broadcasts, periodically within the target cell (11) on a radio channel to the user equipment (13), the target cell identity and a mask. The target cell identity comprises the network node identity of the gateway node (16) embedded in the target cell identity and the mask is to be used to derive the network node identity from the target cell identity.

摘要： A base station, computer readable medium and method for determining whether a neighbor cell is a neighbor of a serving cell, where the serving cell and the neighbor cell belong to a same communication network that includes a user terminal served by the serving cell. The method includes receiving at a base station of the serving cell, via the user terminal, a first identity of the neighbor cell, a second identity of the neighbor cell, and a random number generated by a base station of the neighbor cell; sending, from the base station of the serving cell, a request to the base station of the neighbor cell, for establishing a neighbor relation, wherein the request includes the received random number; and obtaining at the base station of the serving cell a response from the base station of the neighbor cell in response to the request, the response indicating acceptance or denial of the neighbor relation.
