A method of sending information to a radio access node (RAN) of a first radio access technology (RAT) regarding one or more coexisting RAN's of a second RAT is provided. In particular, the information comprises a number of parameters and operating modes used by the one or more coexisting radio access nodes.

Method and apparatus for facilitating network coexistence

In some embodiments, a method comprises blocking mobile devices from establishing new connections to a cell, ending existent connections of mobile devices to the cell gradually based on a shutdown procedure, and locking the cell after the shutdown procedure. The shutdown procedure is configured according to pre-defined parameters that indicate to end the existent connections based on at least one of a priority level of existent connections or an activity level of existent connections.

Soft lock of a cell in a wireless network

Systems and methods relating to coexistence of a cellular communications network technology (e.g., Long Term Evolution (LTE)) and another wireless technology (e.g., WiFi) in a shared unlicensed spectrum are disclosed. In particular, the present disclosure provides systems and methods that mitigate or avoid grabbing of an unlicensed, or shared, frequency band utilized by a wireless communications network node by a node of another wireless technology that operates according to a listen-before-talk scheme.

Systems, methods, and nodes that implement multipath TCP (MPTCP) in a communication system establish first and second data link layer connections to a remote node, notify a transport layer of the establishment of the first and second data link layer connections, and establish first and second transport layer connections with the remote node over the first and second data link layer connections. A packet received at the data link layer for transmission to the remote node is inspected to determine if MPTCP is enabled for the packet, and, in response to determining that MPTCP is enabled for the packet, the packet is assigned to one of the first data link layer connection and the second data link layer connection based on an affinity between an MPTCP sub-flow associated with the packet and the one of the first data link layer connection and the second data link layer connection.

A method and apparatus assigning Physical Resource Blocks, PRBs, to a User Equipment, UE, in a wireless communication network having a plurality of cells, includes determining a Physical Cell Identifier, PCI, of a cell from the plurality of cells. Selecting a power level pattern of multiple PRBs for allocation, and assigning at least one of the multiple PRBs to the UE.

Predictable scheduler for interference mitigation

A method and system for wireless communication in a wireless communication network. The wireless communication network has a first mobile terminal and a second mobile terminal arranged in virtual multiple input, multiple output ('V-MIMO') communication with a base station. A first wireless communication uplink channel corresponding to the first mobile terminal is estimated. The estimate is based on a first reference symbol signal and the cancellation of interference from a second reference symbol signal received from the second mobile terminal. A second wireless communication uplink channel corresponding to the second mobile terminal is estimated. The estimate is based on the second reference symbol signal and the cancellation of interference from the first reference symbol signal received from the first mobile terminal. The estimated first wireless communication uplink channel is used to demodulate a first data signal received from the first wireless device, and the estimated second wireless communication uplink channel is used to demodulate a second data signal received from the second wireless device.

Channel estimation and interference cancellation for virtual MIMO demodulation

The present invention proposes an LTE eNodeB receiver channel estimation technique that is referred to as reduced complexity minimum mean squared error (MMSE) technique for channel estimation. From the invention's assumptions, estimations and modified calculations, the present invention generates precise channel estimates of RS using the reduced complexity MMSE matrix and previously computed LS channel estimates His as follows: (Formula I) which generates precise channel estimates of RS using the reduced complexity MMSE matrix and previously computed LS channel estimates. As a second aspect of the present invention, it is desired that the SNR be estimated within &#x2212;3 dB of the actual channel SNR. As a third aspect of the invention, an adaptive method of data channel interpolation from RS channel is being proposed in this invention.

An Internet Call Waiting (ICW) service provides single-line subscribers () connected to the Internet with incoming call information, call screening and voice messaging capabilities. An incoming call is terminated at an ICW server (). The caller is prompted to leave a voice message and the voice message is relayed in real-time over the Internet connection () to permit the subscriber to monitor the message. The subscriber can choose to answer the call at any time before the caller disconnects. Subscriber profile options specify how calls are treated. Calls may be forwarded to a second directory number, directed to a Voice-over-IP (VoIP) connection, or the Internet connection may be dropped and the call completed to the subscriber's directory number. The subscriber benefits from being able to screen voice messages in real-time, which assists the subscriber in determining how the call should be terminated.

Internet call waiting with voicemail system that provides monitoring during recording

A method of alerting a telemarketing agent of a promotion opportunity in response to activity of a potential customer browsing a public server and an apparatus for monitoring the customer activity and alerting the telemarketing agent includes a telemarketing analysis server, computer telephony hardware and a server for controlling the computer telephony hardware. The apparatus further includes software on the public server for collecting data relating to the activity of potential customers browsing the public server.

Method and system for activity responsive telemarketing

A method and apparatus for providing voice communications between two parties using computer controlled telephony hardware which is separate from the PSTN is described. The voice communications may be voice over Internet or PSTN voice connections, or any combination of the two. The apparatus includes a WEB server, a computer telephony server, a Voice over IP gateway and an operations, administration and maintenance server. The apparatus is suitably installed and operated by a service provider such as an Internet Service Provider. The advantage is unexcelled control over call setup, transfer and conference functions. A further advantage is the rapid, unfettered development of new services without compatibility issues with the PSTN.

Method and apparatus for originating voice calls from a data network

A method and apparatus for call completion using information extracted from an active application on a computing machine is described. Call initiation may be accomplished using a &ldquo;warm-line&rdquo; feature in which a default number is dialled after a predetermined time of an off-hook condition of a voice terminal, if no digits are dialled after the voice terminal is taken off-hook. The number dialled is a number used to connect the telephone set to computer-Controlled Telephony Integration hardware (CTI). On receipt of the call, the CTI hardware extracts Automatic Number Identification (ANI) information to determine the number of the calling party and verifies that the calling party is the subscriber to the service. If the calling party is the subscriber to the service, a query is sent to an IP address associated with the subscriber to retrieve information from an active application for completing a second leg of the call. The information may be a telephone number, or information which would permit the retrieval of a telephone number such as a name and address or an e-mail address. A directory service may be used to convert the information into a telephone number. Once a telephone number is obtained, the CTI hardware is used to complete the second leg of the call and the two calls are joined together. The advantage is a fast, convenient method of completing calls without dialling digits or manually converting one form of information into a diallable number.
