Abstract: A system configured to receive, from a user device, traffic associated with a request to initiate a call session; detect a condition associated with the traffic; determine whether to establish the call session based on whether the condition, associated with the traffic, is a particular type of condition; send, to a server device, a notification to perform an operation to remedy the condition when the condition does not correspond to the particular type of condition, where sending the notification enables the server device to identify a type of condition, identify an operation that remedies the condition based on the type of condition, or initiate the operation to remedy the condition; and establish the call session when the type of condition corresponds to the particular type of condition, where establishing the call session enables a call, placed by the user device, to be processed as a normal call.

Abstract: A mobile terminal receives a class identifier and receives a broadcast message with a backoff period definition for multiple classes of mobile terminals. The mobile terminal applies the class identifier to the backoff period definition to determine a backoff interval for the mobile terminal. The mobile terminal sends, to a base station, a radio resource control (RRC) connection request using the calculated backoff interval. Different backoff intervals are assigned to different classes of mobile terminals to control network access congestion at the base station.

Abstract: A system is configured to receive, from a user device, voice traffic to be sent to another user device; determine whether the voice traffic is local traffic based on whether an eNodeB, associated with the user device, and another eNodeB, associated with the other user device, are served by a particular network device; forward the voice traffic, as non-local traffic, to another network device, associated with a packet data network, for processing when the eNodeB or the other eNodeB are not served by the particular network device; process the voice traffic as local traffic when the eNodeB and the other eNodeB are served by the particular network device; and forward, to the other user device via the other eNodeB, the voice traffic, as local traffic, where the forwarding is performed in a manner that does not include routing the voice traffic via the other network device.

The computing system may also receive a second request from the second voice-communication device to establish the secure-voice-communication session with the first voice-communication device. The computing system may establish the secure-voice-communication session between the first and second voice-communication devices. Corresponding methods, apparatus, and computer-readable media are also disclosed.

Abstract: A user device associates a data session with a particular application, of the user device, that initiated the data session. The user device monitors network data usage for the data session and/or receives network data usage from a monitoring device associated with the network. The device stores and/or retrieves statistics for the network data usage associated with the particular application. The device further retrieves subscription plan information associated with the user device and presents, on a display, the statistics for the network data usage associated with the particular application and in relation to the subscription plan information associated with the user device.

Abstract: A method, performed by a first mobility management entity (MME) device in a network, includes receiving, from a second MME device, standby database information associated with user equipment (UE) registered with the second MME device; detecting that the second MME device has failed or lost connectivity; designating that the UEs registered with the second MME device will be registered with the first MME device, in response to detecting that the second MME device has failed or lost connectivity; detecting a request to activate a particular UE registered with the second MME device; and paging the particular UE to register with the first MME device, using the standby database information and in response to detecting the request to activate the particular UE.

Abstract: A method performed by a device includes detecting a first condition to generate a report record associated with the device; generating the report record associated with the device, in response to detecting the first condition, where generating the report record includes recording environment conditions associated with the device, recording device conditions associated with the device, and recording signal conditions associated with the device; detecting a second condition to send the generated report record to a server device; and sending the generated report record to the server device, in response to detecting the second condition.

Abstract: A method performed by a base station in a network, includes detecting a malfunction associated with a backhaul link to the network; identifying one or more neighboring base stations located within a transmission range of the base station; selecting at least one of the one or more neighboring base stations based on one or more parameters, associated with the one or more neighboring base stations, in response to detecting the malfunction; receiving, by a radio frequency (RF) transceiver associated with the base station, a signal from a user equipment; and transmitting, by an RF transceiver associated with the base station, the signal to the selected at least one of the one or more neighboring base stations.

Abstract: A device receives an encrypted key generating value from a first device and decrypts the encrypted key generating value. A temporary session key associated with the first device is generated based on the key generating value. A secure session invitation message is received from the first device. A master session key is generated and encrypted using the temporary session key associated with the first device. The encrypted master session key is transmitted to the first device.

Abstract: A method for enabling security on a mobile terminal having a communication link with a circuit switched network against suspicious activities is provided. Activities performed at the mobile terminal are performed according to a security policy provided from the circuit switched network. Detection of a suspicious activity is alerted to the circuit switched network when the suspicious activity is detected. A policy manager server of the circuit switched network changes the security policy to cure the suspicious activity on the mobile terminal. Call traffic delivered to/sent from the mobile terminal is filtered out, which causes the suspicious activity according to the security policy. The mobile terminal enforces a security measure on a suspicious activity according to the security policy.

Abstract: To mitigate the impact of a mass communication event, such as a mass voting event, on the resources of the mobile wireless communication network, each user's mobile station is adapted to appropriately adjust its timing of the transmission during the mass communication event. In a voting example, the mobile station delays sending the user's vote by a random time interval. When implemented in a substantial number of mobile stations, the mobile stations randomly delay their individual transmissions, effectively spreading the traffic over a larger time window, thereby reducing the instantaneous peak load on the wireless network. However, since the solution is implemented in the mobile stations, there is no added overhead traffic related to the event at or around the time of the event. Consequently, handling of the event requires less network capacity to account for this bursty traffic.
