  • Patent number: 8654644
    Abstract: The present invention relates to a solution for handling mobility and attachment of users in a wireless communication network (10). User equipment (1) is connected logically to an attachment node (14) at initial attachment and this attachment is determined from an analysis of stored historical mobility patterns of the user equipment. For instance, a mobility management device may be responsible for handling the attachment and for handling the determination of suitable attachment node, e.g. a gateway (5, 7, 8).

  • Patent number: 8428588
    Abstract: The invention therefore relates to a method, a first Mobility Control Node and a second Mobility Control Node for context handling when a user equipment, UE, moves from a previous Access Network, AN, to a present AN. The ANs are adapted to communicate with a Core Network, CN, and the UE is adapted to communicate wirelessly with the AN's. The method comprises the steps of: the UE detecting that it has entered a Mobility Area, MA, belonging to the present AN, said MA not being registered with the CN, the UE initiating a Mobility Area Update, MAU, procedure in response to the detection by sending a MAU Request message comprising an UE Temporary ID to a Radio Access Node, RAN, the RAN adding a Mobility Area Identity, MAI, to the Request message and forwarding the message to a first Mobility Control Node, MCN, responsible for the present AN, the first MCN deriving one second MCN from the UE Temporary ID and sending a context request message to said second MCN.

  • Publication number: 20120246255
    Abstract: A method for operating a communication network includes at least two radio access networks (10-1, 10-2) in which a user equipment (12) can simultaneously be registered and, for each of the at least two radio access networks (10-1, 10-2), a serving entity (14-1, 14-2) in the control plane. The method including the steps of assigning (s16) a master role to one serving entity (14-2) and a slave role to the other serving entity (14-1) or entities; and when a serving entity (14-1) to which a slave role is assigned has to perform control plane signalling (s18), transmitting (s20), by the serving entity, a signalling message to the serving entity (14-2) to which the master role is assigned, so as to perform (s22) the control plane signalling Servers acting as serving entities, systems including such servers, and computer programs executable on the servers are also disclosed.

  • Patent number: 8259677
    Abstract: The invention regards a handover method for a data packet based wireless mobile communications network. The network comprises a core network (CN) and a radio area network (RAN). The core network (CN) comprises a control plane node (MME) intercommunicating with a user plane node (UPE). The radio area network comprises a mobile user equipment (UE) intercommunicating with a source radio base transceiver station, eNOdeB, (source eNodeB), wherein payload data is routed via a tunnel between the user plane node (UPE) and the source eNodeB (source eNodeB), wherein the handover comprises the step of establishing a temporary tunnel between the user plane node (UPE) and a target eNodeB (target eNodeB), the handover being initiated by the target eNodeB (target eNodeB) transmitting an unreliable uplink data signal to the user plane node (UPE) comprising handover information.

  • Publication number: 20120213140
    Abstract: The present invention relates to a method in a user equipment (115) for enabling mobility management node (103) selection in a communication network (100, 200). The user equipment (115) comprises a globally unique identifier assigned by the mobility management node (103). The user equipment (115) obtains (701) information, using the globally unique identifier, about the mobility management node (103) with which the user equipment (115) has been registered. The user equipment (115) transmits (702), when an idle state signaling reduction function, referred to as ISR, is inactive, the information about the registered mobility management node (103) to a base station (105). The information enables the base station (105) to select the registered mobility management node (103).

  • Publication number: 20120184262
    Abstract: Embodiments relate to HLR reset signalling via the s6a interface in EPS. This is provided as nodes and methods for improved utilization of radio resources in a telecommunications network, where Home location registers (HLR) identities related to associated user equipment contexts and associated Mobile Service Centers (MSC) are saved in a mobility management entity (MME). An identity of a restarted HLR is received in the MME and the MME compares the HLR identity with a saved list of HLR identities saved for UE and associated with a respective mobile service center (MSC) server. The MME sets a flag for UE associated with the restarted HLR, the flag indicating an alert. When the MME receives a UE signaling event for a UE with the flag set the MME sends an SGs application Part message to the respective MSC server to indicate that activity from the UE has been detected.

  • Publication number: 20120071173
    Abstract: A method and system for providing a User Equipment (UE) (101) with a Tracking Area Identity (TAI) list during a Tracking Area Update (TAU) procedure. The TAI is UE specific and is based on a visitation history (305) of the UE (101). If a pre-existing visitation history of the UE does not exist, a TAI is compiled using other UEs featuring at least one operational similarity as the current UE (101).
