摘要： In operation, packets traverse the packet processing data structure, and the network processing represented by each object in the data structure is applied to each packet. From time to time, the packet processing data structure may need to be updated. Embodiments of present disclosure provide for lock-free updating of a packet processing data structure by means of epoch-based garbage collection. In embodiments, a particular past packet processing epoch is considered to be no longer referenced by any cores when the sequence numbers recorded in each said memory location are different to the sequence number of that particular past packet processing epoch. The deletion thread checks both whether a past epoch is being referenced by any packets and whether it is being reference by any cores. Thus memory is safely freed without having any impact on any packet processing which may be occurring in parallel to the deletion thread.

摘要： A first call leg for transmittal of audio data associated with a multi-party teleconference call is established between a first telephony device and a multi-party teleconference service. The multi-party teleconference service is capable of connecting the first telephony device with at least two other telephony devices during the multi-party teleconference call. State information indicating that the multi-party teleconference call is of a second call type is stored. During the multi-party teleconference call, an incoming telephone call setup request for the first telephony device is received which is associated with an incoming telephone call of a first call type from a further telephony device which is not a participant in the multi-party teleconference call. The incoming telephone call setup request and the multi-party teleconference call are handled in accordance with the stored state information indicating that the multi-party teleconference call is of the second call type.

摘要： A method of establishing a communications session for communication of data with respect to at least two user devices in a data communications network. Call party details of a telephone call are received. The telephone call involves at least a first telephony user device and a second telephony user device. The call party details include a first identity associated with the first telephony user device and a second identity associated with the second telephony user device. At least one of the first and second identities comprises a telephone dialling number. A separate communications session is established on the basis of the first and second identities received in the call party details. The communications session is separate from the telephone call, for the communication of data to and/or from the at least two user devices. An identifier identifying a feature of the separate communications session that requires authorisation for use by a user device is received. In response to receipt of an authorisation indication from one of the at least two user devices, the use of the feature by at least one other of the at least two user devices is enabled.

摘要： A method of establishing a communications session for data with respect to at least two user devices in a packet switched communications network in parallel to a voice session via a circuit switched network. Call party details of a telephony call are received. The telephony call involves at least a first telephony user device and a second telephony user device. The call party details include a first identity associated with the first telephony user device and a second identity associated with the second telephony user device. A separate communications session is established on the basis of the first and second identities received in the call party details and depending on the capabilities of the user devices. The communications session is separate from the telephone call, for the communication of data to and/or from at least two user devices. An identifier identifying a software component to be used in the separate communications session is received from one of the at least two user devices. The download of the software component to another of at least two user devices is enabled, in response to the receipt of the software component identifier.

摘要： A method of indicating availability in a telecommunications network, the method comprising: initiating an availability alerting service in response to a trigger associated with non-completion of an initial call from a calling party to a called party, the availability alerting service providing the calling party with availability alert information to solicit a follow-up call from the calling party when the called party has a given availability state after the initial call, wherein the availability alerting service is responsive to a plurality of different availability states relating to the called party, and wherein the availability alerting service detects a first availability status change relating to the called party after initiation of the availability alerting service and transmits a first availability update message to the calling party to solicit the follow-up call on the basis of the detected first availability status change, and detects a second availability status change, subsequent to the first availability status change, and transmits a second availability update message to the calling party to at least inhibit the follow-up call on the basis of the detected first availability status change.

摘要： Key data is processed using a hash table data structure. Control data storage locations have a write-availability indicated by first write-availability state indicating that the location is available to be written to, and second write-availability state indicating that the location is not available to be written to. A temporary label value is stored in a selected control data storage location to render selected location and corresponding key data storage location inactive for read-out. The write-availability of the control data storage location is changed to the second write-availability state in association with storage of the processed label value in selected location. A read-out label value is obtained and temporary label value stored in selected control data storage location is over-written with obtained read-out label value, to render selected control data storage location and corresponding key data storage location active for read-out.

摘要： Configuring a virtualized environment in a telecommunications network is described. A plurality of primary virtual workloads are configured, including a first primary virtual workload, to use first processing resources on at least one host device in the network. A plurality of secondary virtual workloads are configured, including a first secondary virtual workload and a second secondary virtual workload, to use second processing resources on at least one host device in the network, each of the plurality of secondary virtual workloads being associated with a respective one of the primary virtual workloads. The secondary virtual workloads contend with one another. Causing, as part of a failover procedure, a processing resource access priority such that additional processing resources on at least one host device in the network are available to the first secondary virtual workload and not available to the second secondary virtual workload.

摘要： Associating a user service with a telephony identifier. The user service is accessible by a user of a telephony device (205) via an application (210) on the telephony device (205). The telephony device 205 is operable in a radio telephony network (RTN) (225) and is contactable via the telephony identifier when operating in the RTN (225). Network equipment (230): communicates, between the network equipment (230) and the application (210) on the telephony device (205), first data comprising a communicated token; receives, from the telephony device (205), second data comprising a received token, wherein the second data is received from the telephony device (205) via an RTN-native service; receives, from a network node (245) in the RTN (225), the telephony identifier in control signalling associated with the RTN-native service; and based at least on correlating the received token with the communicated token, associates the received telephony identifier with the user service.
