Abstract: In accordance with an example embodiment of the present invention, a method is disclosed that comprises deciding at a user equipment (UE) an outage period during which the UE has limited communications with the serving base station; and sending to the serving base station a signaling message indicating the outage period.

Abstract: A network sends an indication of discontinuous reception period (ldle_Mode_DRX_Period) and an indication of number of paging groups (Paging_Group_Count). Paging occasions for a user equipment are determined by a predetermined formula. One exemplary formula is SFN mod IDLE_Mode_DRX_Period=(IDLE_Mode_DRX_Period div Paging_Group_Count) *(ID) mod (Paging_Group_Count); where SFN is system frame number and ID is the identifier of the user equipment, which can be IMSI or some value derived from IMSI. The UE's temporary ID is sent during a determined paging occasion, which maps to a paging channel on which the page is sent. Options for restricting the paging occasion to less than a frame, and for offsetting the paging occasions from that of the above formula are detailed.

Abstract: The invention concerns a method and an apparatus implementing the method. In the method is determined in a mobile node whether the mobile node supports mobile node specific cyclic prefixes. The mobile node transmits to a base station node an indication whether the mobile node supports mobile node specific cyclic prefixes. The base station node measures a delay spread of a radio resource transmitted by the mobile node. The mobile node receives an indication of an uplink direction cyclic prefix length from the base station node. The mobile node forms a cyclic prefix of the uplink direction cyclic prefix length selected from a useful symbol, adds the cyclic prefix in front of the useful symbol and transmits a signal comprising the cyclic prefix and the useful symbol to the base station.

Abstract: In an exemplary embodiment a method includes monitoring traffic in one or more cells; determining that the traffic in one of the cells is congested; and responsive to the determining, initiating a rate change for at least one ongoing connection within the cell. Apparatus and computer programs are also determined for both a user equipment and a network node.

Abstract: Security key stream generation in a communication apparatus. The method includes using a count parameter and a bearer parameter as input, value of said count parameter being incremented as security key streams are generated and value of the count parameter having a finite maximum value; detecting value of the count parameter reaching a predetermined value; and responsive to the detecting, changing value of the bearer parameter into a new value, and resetting value of the count parameter to a value below the maximum value.

Abstract: Methods and apparatuses are provided for avoiding denial of service attacks by rogue access points. A method may include attempting to verify activation of access stratum security by an access point based at least in part upon integrity protection information included in a received security mode command message sent by the access point, wherein a radio connection has been established with the access point. The method may further include detecting an occurrence of a security activation deadlock. The method may additionally include determining that a predefined number of security activation deadlocks with the access point have occurred. The method may also include identifying the access point as a rogue access point based at least in part upon the determination that a predefined number of security activation deadlocks with the access point have occurred. Corresponding apparatuses are also provided.

Abstract: Multiple embodiments are detailed to enable segmenting of system information SI that is sent on a shared channel, In one embodiment, information indicative of a segmentation state of at least one message that comprises system information is generated, and the information indicative of the segmentation state is transmitted to a user equipment, where the information indicative of the segmentation state is provided in one of a L1/L2 control channel, in a broadcast channel, or in a radio resource control message header. Other embodiments stipulate one bit signaling, container types to carry the segmented Sl, headers, segment lengths and other indicators. Certain embodiments specifically address how large block ETWS may be sent in E-UTRAN with low DL-SCH bandwidths.

Abstract: A method for maintaining the accuracy of a clock, comprising the steps of setting the clock time on a first occasion; setting the clock time of on a second occasion; and adjusting the time-keeping operation of the clock on the basis of the time which elapsed between the first and second occasions, and the difference in clock time just prior to the second occasion and as set on the second occasion.
