摘要： A first identifier of a mobile session is generated for a mobile device accessing a network operating in an unlicensed radio band, wherein at least one part of the first mobile session identifier comprises a decimal format consistent with an identifier recognizable by a network operating in a licensed radio band. The first mobile session identifier is compared to one or more previously generated mobile session identifiers currently allocated in the unlicensed radio band network to prevent collision there between.

摘要： In one embodiment, multiple keys are generated in user equipment of a communication system based at least in part on a designated key expansion multiplier. A key identifier is received in the user equipment from a base station of the communication system. The user equipment selects a particular one of the keys as a function of the received key identifier, and utilizes the selected one of the keys to secure data sent from the user equipment to the base station. For example, the keys may comprise respective portions of a key stream generated by the user equipment responsive to a message received from the base station, with the keys being shared by the user equipment and the base station through independent generation of the key stream in the base station. The base station may illustratively comprise an evolved Node B (eNB) of an Evolved Universal Terrestrial Radio Access Network (E-UTRAN).

摘要： We disclose various embodiments that enable a mobile terminal to confirm authenticity of a base station before the mobile terminal proceeds to camp on the corresponding cell. In an example embodiment, the authentication processing includes the mobile terminal tuning to a selected control channel of the base station to monitor RF signals transmitted thereon. The base station is deemed to be authentic if the monitored RF signals indicate the presence of live traffic between the base station and one or more other mobile terminals. The control channel can be selected from a fixed set of uplink and/or downlink control channels that are typically used by a legitimate base station. The presence of live traffic on the selected control channel can be detected by detecting certain control messages that are typically transmitted on that control channel between the base station and one or more mobile terminals served by that base station.

摘要： A neutral host network is configured to provide services supported by any one or more of multiple Participating Service Providers (PSPs) to user equipment in an unlicensed frequency band. The neutral host network includes a neutral host gateway configured for communication with at least one external network, a mobility management entity (MME), and a local authentication, authorization, and accounting (AAA) server configured to determine that a session involving the user equipment is to be detached from the neutral host network. The local AAA server is also configured to transmit, to the neutral host gateway, a first message to initiate session detach of the session involving the user equipment. The neutral host gateway can be configured to transmit a second message to the MME in response to receiving the first message. The MME is configured to perform session detach for the session in response to receiving the second message.

摘要： An example method includes receiving at a User Equipment (UE) a value for an Access Mode identifier and a value for a Closed Subscriber Group (CSG) identifier in one or more cell advertisements, selecting a cell based on the or more cell advertisements, and reporting in a message the value of the Access Mode identifier and the value CSG identifier for the cell advertisement of the cell selected. A core network element receives a first Access Mode identifier value and a first CSG identifier value, these first values associated with a cell advertisement of a cell selected by a UE; receives a second Access Mode identifier value and a second CSG identifier value, these second values reported by the cell selected by the UE; performs a comparison of first and second Access Mode identifier value and/or first and second CSG identifier values; and takes action based on the comparison.

摘要： We disclose various embodiments that enable a mobile terminal to confirm authenticity of a base station before the mobile terminal proceeds to camp on the corresponding cell, e.g., during an idle mode. In an example embodiment, the authentication processing includes the mobile terminal validating a digital signature included in an information block received from a candidate base station, the digital signature having been generated by the base station using an extended time stamp that indicates the calendar year, month, and/or day in addition to the UTC time-counter value. The information block typically includes a truncated time stamp, which the mobile terminal uses to reconstruct the extended time stamp, the reconstruction being performed using a system time stamp that was previously broadcast by the base station. The reconstructed time stamp is then fed, together with other relevant data, into a security algorithm that can confirm the validity of the digital signature.

摘要： An identifier of a mobile session is generated for a mobile device accessing a network operating in an unlicensed radio band (e.g., Neutral Host Network). Generation of at least one part of the identifier comprises generating a random binary value, converting the random binary value into a decimal value, and truncating the decimal value to a number of decimal digits consistent with an identifier recognizable by a network operating in a licensed radio band (e.g., 3GPP Evolved Packet Core).

摘要： We disclose various embodiments that enable a mobile terminal to authenticate a base station before the mobile terminal proceeds to attach to the corresponding network and/or camp on the corresponding cell, e.g., during the initial network selection and attachment or during an idle mode. In an example embodiment, the authentication processing includes the mobile terminal generating and sending to a candidate base station a system query with a nonce. The candidate base station is deemed to be authentic only if the acknowledgement generated and transmitted in response to the system query includes a copy of the nonce properly signed by a digital signature generated using one or more security keys. In some embodiments, the system query may also include a request for GPS coordinates and/or selected system information signed using a digital signature, which the mobile terminal may beneficially use to further strengthen the protection against a spoofing attack.
