20100165928 | UTILIZATION OF MULTIPLE ACCESS POINTS TO SUPPORT MULTIPLE APPLICATIONS AND SERVICES - A method that includes establishing a connection with a default access point, transmitting a request to access or utilize an application, a service, or a resource, receiving a response to the request that includes a location of a serving access point that provides the application, the service, or the resource, establishing a connection with the serving access point, and receiving an assignment of a network address that is anchored by the serving access point. | 07-01-2010 |
20100317350 | SOFT HANDOVER FOR MOBILE DEVICE - A method implemented in a mobile device includes identifying a target wireless network for a handover, where the target wireless network uses a different access technology than an existing wireless network being used by the mobile device. The mobile device determines that a signal for the existing wireless network meets an early registration trigger threshold and initiates, based on the determining, an early registration of the mobile device with the target wireless network, where an early registration is performed at a sufficient time prior to the actual handover to preclude a registration delay associated with the handover to the different access technology. | 12-16-2010 |
20110007706 | RADIO ACCESS NETWORK (RAN) CAPACITY/RESOURCE DETERMINATION - A device receives code division multiple access (CDMA) capacity/resource information via a first direct interface with a radio network controller (RNC) associated with a CDMA radio access network (RAN), and determines, based on the CDMA capacity/resource information, a capacity associated with the CDMA RAN. The device also determines, based on the CDMA capacity/resource information, a resource availability associated with the CDMA RAN, and determines, based on the capacity and the resource availability associated with the CDMA RAN, a CDMA RAN resource allocation. | 01-13-2011 |
20110040882 | DYNAMIC HANDLER FOR SIP MAX-SIZE ERROR - A network device forwards a Session Initiation Protocol (SIP) setup request from an originating user device toward a destination user device via multiple network elements and intercepts a message-too-large error message sent from one of the multiple network elements to the originating user device. The network device automatically splits the session setup request into smaller SIP messages, where a size of each of the smaller SIP messages is less than or equal to a particular size of message that the network element will accept. The network device then notifies another one of the multiple elements that the session setup request has been split into the smaller SIP messages and sends, via the multiple network elements, the smaller SIP messages toward the destination user device on behalf of the originating device. | 02-17-2011 |
20110051712 | INTERNET PROTOCOL MULTIMEDIA SYSTEM (IMS) MOBILE SESSION INITIATION PROTOCOL (SIP) AGENT - A first phone obtains an identifier of a second phone from a phone list, and sends a request for the second phone's Session Initiation Protocol (SIP) type to a remote server. The first phone receives the second phone's SIP type from the remote server, and sends a message to one or more nodes in a network, based on the received second phone's SIP type, for a SIP session between the first phone and the second phone. | 03-03-2011 |
20110099293 | INTERNET PROTOCOL (IP) ADDRESS POOL MANAGEMENT AND ALLOCATION - A device receives Internet protocol (IP) traffic flow data from network devices of a wireless network, groups the network devices into sets based on the IP traffic flow data, and estimates, based on the sets, information associated with the network devices. The device also groups the network devices into clusters based on the estimated information, ranks the clusters, and assigns IP address pools to each of the network devices based on the ranked clusters. The device further provides the assigned IP address pools to authorization, authentication, accounting (AAA) devices of the wireless network. | 04-28-2011 |
20110134880 | LONG TERM EVOLUTION (LTE) MOBILE ANCHORING - A device receives roaming information associated with a user equipment (UE), a current eNodeB conducting a current Internet protocol (IP) session with the UE, and a plurality of eNodeBs that are neighboring the current eNodeB. The device also selects, based on the roaming information and from the plurality of eNodeBs, an optimal eNodeB to which to handover the UE, and establishes a preemptive IP session with the optimal eNodeB. The device further initiates a handover of the current IP session and the UE from the current eNodeB to the optimal eNodeB, where the current eNodeB acts as an anchoring point for a bearer path associated with the UE during the handover. | 06-09-2011 |
20110141947 | INTEGRATED LAWFUL INTERCEPT FOR INTERNET PROTOCOL MULTIMEDIA SUBSYSTEM (IMS) OVER EVOLVED PACKET CORE (EPC) - 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. | 06-16-2011 |
