摘要： A method, apparatus and computer program product are provided to facilitate security in response to a handover from an initial network to a subsequent network, such as a handover between a packet-switched network and a circuit-switched network. The method, apparatus and computer program product may provide at least one security key for use in the subsequent network following handover from the initial network such that communications conducted via the subsequent network, including initial communications, may be secure. In order to provide at least one security key for use in the subsequent network, at least one security key of the initial network may be identified along with a nonce in response to a determination that a handover is to be made. The at least one security key of the subsequent network may then be determined based upon the at least one security key of the initial network and the nonce.

摘要： A method, apparatus and computer product are provided that may respond to an unrecoverable error without initiating a cell update procedure. In an instance in which more than one connection is concurrently supported in either the circuit switched domain, the packet switched domain or both, the method, apparatus and computer program product may avoid interrupting or terminating the connection that did not experience the unrecoverable error. For example, in an instance in which the unrecoverable error occurred on a radio bearer for a data service connection, such as a packet switched data call, the method, apparatus and computer program product may address the unrecoverable error without disruption of a connection for a voice service, such as a circuit switched voice call.

摘要： A wireless device may receive a radio link control (RLC) protocol data unit (PDU) from a lower layer (e.g., from a media access control (MAC) layer) when processing communications (e.g., packets) received from another wireless device. The receiving wireless device may identify that the PDU is an RLC service data unit (SDU) segment based at least in part on an indication corresponding to a sequence number associated with the RLC SDU segment. The receiving wireless device may then determine that the RLC SDU segment is received out of order based on previously received PDUs or previously received RLC SDU segments, and initiate a reassembly timer based on the out of order determination for the RLC SDUs. If the remaining RLC SDU segments (e.g., that complete the RLC SDU) are received before reassembly timer expires, the wireless device may reassemble the RLC SDU to be passed to a higher layer.

摘要： Various methods for managing carrier measurements are provided. One example method includes capturing a secondary carrier intra-frequency measurement for a secondary carrier frequency and determining that the secondary carrier measurement satisfies secondary carrier event criteria. The secondary carrier event criteria may be derived from an anchor carrier measurement parameter. The example method may also include generating a measurement report in response to the captured secondary carrier intra-frequency measurement satisfying the secondary carrier event criteria. The measurement report message may include an event identifier associated with the satisfied event criteria. Similar and related example methods and example apparatuses are also provided.

摘要： A method, apparatus and computer program product are provided to determine if a measurement event is satisfied by one or more detected cells and to correspondingly advise the network to facilitate consideration of whether a handover or cell reselection procedure is desired. The network may, in turn, determine whether the detected cell(s) that satisfied the measurement event are appropriate to be considered in conjunction with a handover or cell reselection procedure, such as by being in the same public land mobile network (PLMN) as opposed to being in a different PLMN and/or cells that are barred or reserved for operator use. Thus, the network may take advantage of opportunities for handover or cell reselection offered by a detected cell, while still insuring that handover or cell reselection procedures remain limited to cells that are appropriate.
