Abstract: In case the first indicator specifies a number of anycast members greater than the second indicator, the number of nearest anycast members indicated by the second indicator (in the following: second number of anycast members) are skipped and not contacted, while a number of anycast members is determined for data communications with the sender up to a number obtained by a comparison of the number of anycast members specified by the first indicator (in the following: first number) and the second number. In particular, the number of nearest anycast members to be determined corresponds to the differen e between the first number and the second number. In case the first number corresponds to the second number, no further anycast members have to be determined. The same applies for the case wherein the first number is smaller than the second number.

Abstract: A method of controlling the operation of a communication system is described, where the system comprises a first entity 2 for sending a first data object 21 to a terminal device 4 and a second entity 3 for sending a second data object to the terminal device at the request 41 of the terminal device 4. The communication system also comprises a data transfer entity 11 and a charging entity 5. The data transfer entity 11 records charging relevant parameters related to the transfer of the first data object. It is proposed that the second entity 3 is controlled to output a predetermined triggering message to the data transfer entity 11 and/or charging entity 5, where the operation of processing the charging relevant parameters in a charging procedure is postponed until the predetermined message is received.

Abstract: A distributed caching and redistribution system, method, and mobile client for caching and redistributing data content in a wireless data network. The system enables mobile clients to cache data content that has been distributed by means of broadcast or multicast, and to redistribute the content from the cache to other users. Using anycast techniques applied to the PLMN, a user who wants to retrieve data that was distributed earlier locates the nearest user that has the content available, and asks the nearest user to forward the content. The “nearest” user may be the closest user, but may also be the optimal user from a Quality of Service (QoS) point of view.

Abstract: A message is distributed from a source to one or more hosts in a communications network that comprises one or more multicast capable routers. To do this, a first multicast capable router generates a first table that identifies sub-branches connected to the first multicast capable router, and for each identified sub-branch, includes membership-related information from which it can be determined how many hosts are part of the sub-branch and (optionally) a metric associated with each of the sub-branch hosts. The multicast capable router then receives the message to be distributed and a first value, N1, that specifies how many hosts the message is to be distributed to, and uses the first table to identify N1 hosts and their respective sub-branches. It distributes the message to each of the identified sub-branches along with a second value that specifies how many hosts within the sub-branch the message is to be distributed to.
