摘要:
A method for performing cell re-selection in a cellular network includes a subscriber terminal measuring received powers of neighbour cells in accordance with system information received from a current cell, selecting one of the neighbour cells as a new cell, the subscriber terminal receiving a part of the system information sent by the new cell, calculating the time used for receiving the system information of the new cell by employing the length information in the system information part sent by the new cell, and deciding whether to continue the re-selection of said new cell on the basis of the calculated time.

A method includes receiving location area-related information, associating the location area-related information with a neighbor cell information to determine if a cell belongs to a forbidden location area, and avoiding selection of the cell if the cell is determined to belong to the forbidden location area. Embodiments described include a UE, network element, computer program product, and integrated circuit.

An apparatus for providing closed subscriber group access control may include a processor. The processor may be configured to maintain a non-access register including an identifier of a communication cell associated with a closed subscriber group to which a communication device associated with the non-access register does not have access rights, and enable subsequent communication with another communication cell based on the other communication cell not being identified in the non-access register. A corresponding method and computer program product are also provided.

A method of managing a handover of a connection of a mobile device between a first access node and a second access node in a communications system, the method comprising: sending information from the communications system to the mobile device; selecting one of a plurality of access methods for accessing the second access node based on said information; and accessing the second access node using the selected access method.
摘要:
A user equipment (UE) receives a first dynamic resource allocation on a first channel (PDCCH), then sends data according to the first resource allocation. During a time at which an ACK/NACK for the sent data is scheduled to occur on a second channel (PHICH), the UE is engaging in an activity that takes priority over the ACK/NACK. The UE then receives a second dynamic resource allocation on the first channel and determines the ACK/NACK for the sent data from the second dynamic resource allocation. The determining can be direct, as in receiving a zero-valued resource allocation; or it may be indirect as in mapping the second dynamic resource allocation to the second channel and receiving the acknowledgement on the second channel after that mapping. Also detailed are similar mirror actions from the Node B's perspective, as well as apparatus, methods, and embodied computer programs.

In accordance with aspects of the present invention, a method, an apparatus, a system, and software are provided to link channel quality indication reporting with periods when communication terminals, such as user equipment, are active. In one aspect, an apparatus (e.g., a communication terminal) includes a determination module configured to determine when at least one component of the apparatus is in an inactivated state. The apparatus also includes an interrupter configured to interrupt a transmission of at least one channel quality indication report when the at least one component is in the inactivated state. In another aspect, a method includes determining when at least one component of a communication terminal is in an inactivated state and interrupting transmitting at least one channel quality indication report when the at least one component is in the inactivated state.

The exemplary embodiments of the invention utilize techniques that provide an amount of scheduling flexibility for retransmissions (e.g., downlink HARQ retransmissions) while also limiting the amount of time within which a UE can expect retransmissions. Thus, the network retains scheduling flexibility while the UE can still operate in DRX, for example. In one exemplary embodiment, a method includes: receiving an initial transmission of information; and receiving a retransmission of the information, where the retransmission is received within a window of time having a predetermined duration, where the window of time is arranged to begin at a predetermined time or after a predetermined time interval. In further exemplary embodiments, the predetermined duration of the window of time is measured using a DRX retransmission timer and/or the predetermined time or the predetermined time interval is measured using a HARQ RTT timer.
摘要:
Mobility in E-UTRAN might not rely on neighbor cell list. In such a case, the user equipment (UE) may be responsible for finding cells and reporting to the network. Consequently signaling load may be increased and also handover (HO) performance can be degraded for the cases in which the target cell proposed by the UE is not good. Certain embodiments of the present invention give the operator some control of the signaling load and HO performance by providing a list of forbidden cells with regard to which the UE does not have to search and report.
摘要:
Apparatus, methods and computer program products operate an electronic device to receive through from a wireless communications network a prioritized list of radio access technologies; to store the prioritized list of radio access technologies in a memory of the electronic device; and to consult the prioritized list of radio access technologies during cell selection and reselection operations. In variants the radio access technologies listed in the prioritized list of radio access technologies can be E-UTRAN, UTRAN or GERAN. In a further variant to consult the prioritized list may mean to compare at least one of a signal measurement and a quality measurement with at least one threshold established for a certain radio access technology appearing in the prioritized list, and to select/reselect to the certain radio access technology only if the at least one of the signal measurement and the quality measurement exceeds the threshold.
摘要:
An approach is provided for receiving and transmitting data over a wireless network, while minimizing power consumption. A determination is made, as part of a discontinuous communication mechanism defining an on-period for permitting transmission of data over a network, whether a resource allocation has been made to a user equipment for communicating over the network. If the resource allocation has been made, generating a keep-awake message to instruct the user equipment to extend the on-period.
