Abstract: Policy control and charging functionality in a network receives information indicating tariffs for a call session associated with a user equipment. The policy control and charging functionality defines, based on the information indicating the tariffs, a policy governing allocation of one or more licensed frequency bands and one or more unlicensed frequency bands to the call session. The policy and control charging functionality transmits the policy to a base station associated with the user equipment.

Abstract: Systems and methods for filtering emergency broadcast messages. One embodiment is User Equipment (UE) that store rules for filtering emergency broadcast messages. The UE receives an emergency broadcast message over a paging channel of a mobile network, identifies a class indicator assigned to the emergency broadcast message, selects one of the rules based on the class indicator assigned to the emergency broadcast message, and determines whether the emergency broadcast message is authorized for presentation on the UE based on the rule. The UE then ignores the emergency broadcast message responsive to a determination that the emergency broadcast message is not authorized for presentation.

Abstract: IMS networks and methods are disclosed for charging for operator-assisted sessions. To perform the charging, an operator assistance application server (AS) acts as an interface between an operator system (legacy or IMS) and charging systems for the IMS network. When an operator-assisted session is initiated in the IMS network, the operator assistance AS receives a session initiation message in SIP, and transmits the session initiation message to the operator system to allow the operator system to collect charging information from an end user. The operator assistance AS then receives a service request message from the operator system that includes the collected charging information, and detects a charging event. The operator assistance AS generates a Diameter charging request message, maps the charging information from the service request message to the Diameter charging request message, and transmits the Diameter charging request message to a charging system to charge for the operator-assisted session.

Abstract: One embodiment is a relay User Equipment (UE) enabled for UE-to-network relay. The relay UE determines relay capabilities for acting as a relay to re-transmit traffic between a remote UE and a network. The relay UE generates synchronization signals for synchronizing with other relay UEs in proximity for device-to-device (D2D) communication, and inserts an indication of the relay capabilities in the synchronization signals. The relay UE transmits the synchronization signals over-the-air to the other relay UEs.

Abstract: A user equipment determines a set of licensed and unlicensed frequency bands that are available for wireless communication. The user equipment selects a first subset of the set as targets for a handover involving at least one unlicensed frequency band and transmits information indicating the first subset. A base station receives information indicating a first subset of a set of licensed and unlicensed frequency bands. The first subset are targets for a handover of user equipment involving at least one unlicensed frequency band. The base station selects a second subset based on the first subset and transmits information indicating the second subset.

Abstract: A base station receives a charging policy indicating data usage tariffs for licensed and unlicensed frequency bands. The base station selectively allocates one or more of the licensed or unlicensed frequency bands to user equipment based on the data usage tariffs. A network charging system transmits a charging policy indicating data usage tariffs for licensed and unlicensed frequency bands. The network charging system receives a message including charging parameters for data usage by one or more of the licensed or unlicensed frequency bands that are selectively allocated based on the charging policy.

Abstract: Systems and methods for spam detection within electronic messages transported over a communication network. One embodiment is a spam center that connects to multiple entities of a communication network that handle electronic messages, such as text messages. The spam center receives spam reports from the entities that detect spam in prior electronic messages, analyzes the spam reports to generate spam filtering rules based on the spam detected in the prior electronic messages. The spam center then distributes the spam filtering rules to one or more of the entities. The entities may then use to spam filtering rules to filter spam out of electronic messages that subsequently received.

Abstract: An example method includes receiving at a cell broadcast center information for distribution to at least one user equipment. The cell broadcast center determines an alert category and a message number for the alert category. The alert category is based on the information for distribution. The alert category is associated with one or more corresponding alert categories of a plurality of technology networks with which the cell broadcast center is configured to interact. The message number for the alert category is based on a number of alert messages previously forwarded for the alert category. An alert message is forwarded from the cell broadcast center to the at least one user equipment via one or more of the plurality of technology networks. The alert message includes the message number for the alert category and an alert category indicator indicating a respective corresponding alert category of the one or more corresponding alert categories that corresponds with the alert category.

Abstract: A example method includes receiving, at a cell broadcast center (CBC) an alert request providing information for distribution to at least one user equipment, identifying a broadcast area based on the alert request, one or more cells within the broadcast area, determining a warning area list (WAL) for a message and transmitting the message with the WAL. The WAL may be a list of one or more Tracking Area Identity (TAIs) or a list of cell identifiers depending on various conditions.

Abstract: Charging systems and methods are disclosed for determining the share of call revenue for multiple entities. One embodiment comprises a charging controller that is coupled to a mobile network and an online charging system. The charging controller receives charging data for a call in the mobile network, and processes the charging data and charging rules to identify entities that have a share in revenue for the call. The charging controller generates a charging request message indicating the entities having a revenue share in the call, and transmits the charging request message to the online charging system to cause the online charging system to determine the revenue share for each of the entities.

Abstract: Mobile units are handed over from LTE to carrier grade WiFi. The LTE can be licensed (LTE-L) or unlicensed (LTE-U). Charging mechanisms for co-located and integrated WiFi are also provided. When an LTE-U capable mobile unit moves into the LTE-U coverage area of a small cell, the mobile unit can use the unlicensed spectrum for a data session, thereby effectively increasing the data capacity of the network. When the mobile unit moves within the carrier grade Wi-Fi coverage area of the small cell, the small cell can handover the entire data session to the carrier grade Wi-Fi access point, thereby freeing up LTE system resources to provide data services to other mobile units.

Abstract: Systems and methods for switching radio resource allocation for User Equipment (UE) enabled for a device-to-device (D2D) communication. One embodiment is a base station that switches resource allocation between Mode 1, Mode 2, and a transition mode. For the transition mode, one or more parameters have a value in a range between a value specified in Mode 1 and a value specified in Mode 2 for the parameter(s). The base station detects movement of the UE from in-coverage of the base station to edge-of-coverage, and initiates switching of the resource allocation for the UE from Mode 1 to the transition mode. The base station then detects movement of the UE from edge-of-coverage of the base station to out-of-coverage, and initiates switching of the radio resource allocation for the UE from the transition mode to Mode 2.

Abstract: An apparatus, e.g. a mobile computing device, directs presence information toward a presence server (PS). The presence information includes public-safety (PuSa) specific proximity-based services (ProSe) information. The apparatus also directs to the PS a request to subscribe to PuSa-specific ProSe information of a target ProSe presentity, the request including a dedicated PuSa service ID. The apparatus may discover user equipment (UE) of the target presentity only on the condition that the PS returns the presence information of the target presentity.

Abstract: Embodiments described herein provide usage authorization control for group communications. In one embodiment, a network element identifies a group communication for an end user of User Equipment (UE), and identifies a group ID for the group communication. The network element retrieves a user profile of the end user from a Home Subscriber Server (HSS), and determines from the user profile and the group ID whether the end user is a member of the group. The network element provides, on the condition that the end user is a member of the group, the group ID to the HSS and receives group usage rules for the group from the HSS. The network element allows the group communication on the condition that the group communication is permitted by one or more of the group usage rules.

Abstract: Systems and methods that handle partial Charging Data Records (CDRs) for a session. An offline charging system includes a cluster of Charging Gateway Functions (CGF). A first CGF of the cluster receives a first Fully Qualified Partial CDR (FQPC) for a session, and stores FQPC data based on the first FQPC in a centralized storage module that is accessible by each of the CGFs in the cluster. A second CGF of the cluster receives a Reduced Partial CDR (RPC) for the session responsive to a failure of the first CGF, retrieves the FQPC data from the centralized storage module, and generates a second FQPC for the session based on the RPC and the FQPC data retrieved from the centralized storage module.
