摘要:
A method and a radio node (RN) shared by operators of separate cellular networks having operator specific tracking area plans. The radio node (RN) broadcasts (1:1) system information with network identities of the cellular networks (PLMN IDs) and multiple operator specific tracking area codes (TACs) valid in respective tracking area plans of the cellular networks, each tracking area code being associated with a corresponding network identity in the system information. Thereby, the operators are enabled to use their own operator specific tracking area codes for their respective operator specific tracking areas that include a cell (100) covered by the radio node.

Methods and systems described herein may provide for the updating, maintenance, and/or transference of a CSG White List that is stored on a user equipment. The CSG White List may be implemented to store information related to the access of CSG cells, such as, for example, femto cells. Additionally, methods and systems described herein may provide for the updating, maintenance, and/or transference of an access control database. The access control database may be stored in one or multiple devices in a communication system. The access control database may be implemented to store information regarding home nodes and which user equipment is allowed to access the femto cell or CSG cell provided by each home node.
摘要:
The invention relates to handover of a mobile station (12) from a source cell to a target cell when the identity of the target cell in a wireless communication network (10, 11) is ambiguous, a source base station (14) defining the source cell receives an event from the mobile station comprising a cell identifier, investigates if there are more cells in the neighborhood sharing the same cell identifier and sends a handover instruction to the mobile station comprising an identity ambiguity indicator if there are more cells sharing the same cell identifier. The mobile station autonomously initiates establishment of a connection to a target base station defining the target cell based on the identity ambiguity indicator in order to effect handover.
摘要:
A method of controlling a radio access network entity of a data unit communication network is described, said radio access network entity being involved in providing a transport service to a radio terminal of said data unit communication network, said transport service being characterized by a set of values associated with respective service quality parameters, said method comprising: monitoring (S30) a communication quality at the radio access level of a communication between said terminal and an access point of said radio access network, and setting (S31) a congestion indication marking in data units of said transport service if said communication quality fulfils a radio communication degradation condition.
摘要:
A first and a second base station, and respective methods therein are provided for enabling communication between the first base station and the second base station, wherein one of the base stations enables the other base station to obtain synchronization information. One of the base stations has information of a time server it is using for obtaining synchronization information. When one of the base stations detects the presence of the other, this time server information is sent to the base station not having the time server information, thereby enabling this base station to obtain synchronization information from the same time server as its counterpart.
摘要:
A method comprises maintaining, in a first node serving a mobile terminal over a connection protected by at least one first key, said first key and information about the key management capabilities of the mobile terminal. Upon relocation of the mobile terminal to a second node the method includes: if, and only if, said key management capabilities indicate an enhanced key management capability supported by the mobile terminal, modifying, by said first node, the first key, thereby creating a second key, sending, from the first node to the second node, the second key, and transmitting to the second node the information about the key management capabilities of the mobile terminal.
摘要:
The described technology generally relates to method(s) and arrangement(s) for access control during relocation of a user equipment (UE) into a femto base station (FBS) and dynamic triggering of the relocation into the FBS. A white list is maintained in the UE. The white list includes information on a list of FBSs that the UE is allowed to relocate. The UE detects a target FBS and reports target FBS to a source macro base station (MBS). The source MBS makes a relocation request to a mobility controller. The mobility controller grants or denies the requests or allows the target FBS to make the decision. Upon grant, the UE is relocated to the target FBS. Otherwise, the white list is updated in the UE.
摘要:
The invention relates to a method for a mobile communications, a mobile communication device (1), a node (N1, N2) in a mobile communications network (RAN, CN). The method comprises the step of sending a service request (307) from a mobile communication device (1) to a mobile communications network (RAN, CN), and in the method, the following steps are carried out before sending the service request (307): detecting an activity (301) related to the mobile communication device (1), and performing (304), in response to the detection (301) of the activity, at least one measurement of at least one candidate for serving a communication session.
