Certain aspects of the present disclosure provide methods and apparatus for implementing Automatic Neighbor Relation (ANR) functions for relay nodes (RNs), home base stations (eg, home evolved Node Bs (HeNBs), and related entities (eg, donor evolved Node Bs (DeNBs) and HeNB gateways) X2 is designed to be an end-to-end protocol between two evolved Node Bs (eNBs) However, for the case of RNs or HeNBs, this protocol may involve a proxy function (eg, where the DeNB acts a proxy for the RN) This creates several issues, such as how to manage a potentially very large set of cells under a gateway and how to route S1 messages used for X2 endpoint discovery Therefore, certain aspects of the present disclosure generally relate to methods and apparatus for maintaining the X2 connections intelligently and hiding the large number of nodes from the X2 endpoints based on various triggers

Automatic neighbor relation (anr) functions for relay nodes, home base stations, and related entities

A system and method for predicting future locations of mobile communication devices utilizes connection-related data from a mobile access network supporting the mobile communication devices to determine latest locations of the mobile communication devices, which are used to predict the future locations of the mobile communication devices. In addition to the determined locations of the mobile communication devices, carrier-provided location predictive indicators and/or non-carrier location predictive indicators may be used to improve the accuracy of the predicted future locations.

System and method for predicting future locations of mobile communication devices using connection-related data of a mobile access network

An interaction server controls access between a plurality of senders and/or users exchanging electronic interactions. A sender may identify a user with whom the sender desires to interact using a public identifier associated with the user. The interaction server may coordinate the desired interaction without revealing private information, such as information about private user resources (e.g., personal contact information, personal payment information, personal data, etc.). The interaction server may determine whether to provide an interaction by evaluating an access code, by determining whether a user is trusted, and/or the like. The interaction server may provide the interaction, a notice of the interaction, a payload associated with the interaction, and/or the like to a user resource associated with the public identifier if access is allowed.

Systems and methods for access-controlled interactions

Disclosed is a communication system for effecting communication events between a plurality of endpoints connected via a communication network. The communication system comprises a plurality of processing units other than said endpoints, each having access to computer storage holding executable code modules for managing a communication event. The code modules are configured to implement a media modality controller configured to manage media modality of an established communication event and a call controller configured to establish the communication event. An instance of the call controller is assigned to progress the establishment of the communication event responsive to an instruction received via the network and is configured to initiate an instruction to at least one of: the media modality controller; and at least one of the endpoints.

Communication system architecture

Systems and methods are provided for supporting IPv4-IPv6 interworking of SIP messages in wireless networks and IMS networks The interworking can be provided to smooth migration to an all-IPv6 IMS network by allowing the use and support of existing legacy IPv4 infrastructure This functionality may be provided by a call session control function (CSCF) interposed between a user equipment (UE) and an IMS core network with interworking functionality or an interworking module This device serves as a back-to-back user agent (B2BUA), allocates IP addresses from a pool, performs next-hop route protocol discovery, and maintains and stores information within the gateway as well as interworking and rewriting IP addresses within network messages, while proxying and maintaining sessions between the UE and the IMS core network This allows for faster call setup, reduced capex/opex, improved debuggability, increased capacity and subscriber density by call processing distribution, and better user experience

Ip address version interworking in communication networks

A method and a system provide integrated lawful intercept, for IMS over an Evolved Packet Core (EPC), for both packet data and session initiation protocol (SIP)-based applications. The system includes a device that receives a lawful intercept request from a law enforcement agency, and determines whether a packet data lawful intercept or a SIP-based applications (SBA) lawful intercept is requested by the lawful intercept request. The device also provisions, when a packet data lawful intercept is requested by the lawful intercept request, a policy control and charging rules function (PCRF) and a packet data network (PDN) gateway (PGW) for the packet data lawful intercept. The device further provisions, when a SBA lawful intercept is requested, a proxy call session control function (P-CSCF), a serving-CSCF (S-CSCF), and a session border controller (SBC) for the SBA lawful intercept.

Integrated lawful intercept for internet protocol multimedia subsystem (ims) over evolved packet core (epc)

A server device configured to store an Internet protocol (IP) registry, the registry includes information for a user device, the information includes particular identifiers for the user device, an IP address for the user device, and a particular access point name (APN), where the particular APN corresponds to a service, an application, a network, or data used by the user device; receive a query that includes identifiers and an APN; perform, using the IP registry, an operation to identify the information, for the user device, based on the identifiers and the APN; obtain the information for the user device, when the identifiers match the particular identifiers stored in the IP registry and when the APN matches the particular APN stored in the IP registry; and send, to an application server, the information for the user device, where the IP address permits the application server to communicate with the user device.

Dynamic internet protocol registry for mobile internet protocol based communications

A method may include receiving a session initiation protocol (SIP) Invite message associated with a call and determining that the call involves location based processing. The method may also include identifying location information associated with the call based on header information included in the SIP Invite message and identifying a location ID based on the location information. The method may further include modifying the SIP Invite message to include the location ID, identifying a call type associated with the call and identifying a mobile switching center to which the SIP Invite message is to be forwarded based on the call type and the location information.

Location based routing

A method may include receiving a request from an Internet Protocol Multimedia Subsystem, where the request relates to an Internet Protocol Multimedia Subsystem service associated with user equipment The method may further include obtaining location or time zone information associated with the user equipment from an access network; providing the obtained location or time zone information to the Internet Protocol Multimedia Subsystem; and providing the obtained location or time zone information to an on-line or off-line charging system

Providing user location and time zone information for lte/ims charging

A network device may receive an incoming call for a user device requesting a communication session corresponding to a particular communication session type, where the user device is attached to a first access network. The network device may identify the first access network and determine whether a first centralized network supports the communication session type in the first access network. When the first centralized network supports the communication session type in the first access network, the network device may designate the first centralized network to service the incoming call. When the first centralized network does not support the communication session type in the first access network, the network device may designate a second centralized network to service the incoming call.
