Abstract: Techniques are described for upgrading a virtualized network function (VNF) implemented in a virtualized computing environment configured in a user-specific configuration. The virtualized network function is implemented by a plurality of VNF components (VNFCs) executing in a plurality of virtual machines managed by a virtualized infrastructure manager (VIM). An upgrade component is configured to execute as a virtual resource and execute a series of operations that coordinate an upgrade of the VNFCs implementing the VNF and interact with the VIM and the virtual machines to effect the upgrade. A configuration file pertaining to a new software version defining the upgrade and a set of upgrade instructions. Based on the configuration file, the upgrade instructions are translated to a series of operations on the virtual machines and interactions with the VIM to effect the upgrade.

Abstract: A device receives call information associated with a call from a first user device to a second user device, where the first user device is associated with a first network, and the second user device is associated with a second network separate from the first network. The call information includes a caller identification and is received via an originating network device of the first network. The device determines whether the caller identification is verified, and adds authentication information to the call information when the caller identification is verified. The device receives the call information and the authentication information from a terminating network device of the first network, and removes the authentication information from the call information. The device adds a cryptographic signature to the call information, and causes the call information and the cryptographic signature to be provided to the second network for routing to the second user device.

Abstract: A computer file is processed at a first network entity (NE). At least part of the file is received from a second NE. Data relating to the received at least part of the file is transmitted to a third NE and: (i) comprises a file name of the file, the file name being transmitted to the third NE before the first NE received at least one other part of the file; and/or (ii) indicates that the first NE is processing the at least part of the file; and/or (iii) indicates that the first NE is in the process of receiving the file. Confirmation data is received from the third NE, confirming that the third NE has received the transmitted data. A file transfer acknowledgment is transmitted to the second NE on the conditions that the first NE (i) has successfully received the file and (ii) has received the confirmation data.

Abstract: There is provided a method for processing communications in a telephony network. The method includes configuring a first telephony identifier for communication with a first user and a second user, and a second telephony identity for communication with the second user, each of the telephony identifiers being configured for use as different destination addresses in different SMS messages sent to the second user. The method includes processing at least one SMS message in SMS processing equipment in the network, and during this processing, performing identity management, in relation to the use of the first and second telephony identifiers for the second user.

Abstract: A first telephony identifier and a second telephony identifier are used for communication with a first, multi-identity user. Each of the first and second telephony identifiers are configured for use as different destination addresses in different SMS messages sent to the first user. At least one SMS message is processed in SMS processing equipment in the network, and the SMS processing equipment performs identity management, in relation to the use of the first and second telephony identifiers for the first user, during processing of the at least one SMS message.

Abstract: A method of processing call setup signalling at a telecommunications switch. The telecommunications switch receives call setup signalling, comprising at least a caller ID. The telecommunications switch is connected via a plurality of trunks which connect the telecommunications switch to two or more other telecommunications switches capable of transmitting call setup signalling to the telecommunications switch. The telecommunications switch detects at least one of the plurality of trunks via which the call setup signalling has arrived at said telecommunications switch. The telecommunications switch determines a call handling option to be applied to the incoming call setup signalling based at least in part on the detecting and the caller ID.
