Abstract
Systems, methods and computer programs for transferring data in a communication system are described. The communication system has a first node arranged to send data to a plurality of second nodes using a first protocol. The first protocol allows the transfer of data of a first type. At least one of the second nodes additionally requires data of a second type, which is not included in the data sent according to the first protocol. First data, of the first type, is transferred to a plurality of the second nodes using the first protocol. Second data, of the second type, is stored in a memory. Subsequently, in response to a request, access to the second data is provided to the second node.
Claims19
A method of data transfer in a communications system, the communications system comprising a first network node arranged to provide a first type of data and a second type of data to a second network node that requires the first type of data and the second type of data, the method comprising:
- receiving, by the second network node, the first type of data via a third network node using a first protocol, the first protocol defining a set of data fields corresponding to the first type of data, wherein the third network node receives the first type of data from the first network node according to the first protocol and transmits the first type of data to the second network node according to the first protocol, and wherein the third network node lacks support for transferring the second type of data;
- requesting, by the second network node, the second type of data from a memory that is external to the first, second, and third network nodes, wherein the second type of data does not correspond to any of the data fields defined by the first protocol;
- and
- obtaining, by the second network node, the second type of data stored in the memory without requiring updating of the third network node to support transferring the second type of data.
A non-transitory computer-readable storage medium having computer readable instructions stored thereon, the computer readable instructions being executable by a computerized device to cause the computerized device to perform operations for data transfer in a communications system having a first network node arranged to provide a first type of data and a second type of data to a second network node that requires the first type of data and the second type of data, the operations comprising:
- receiving the first type of data via a third network node using a first protocol, the first protocol defining a set of data fields corresponding to the first type of data, wherein the third network node receives the first type of data from the first network node according to the first protocol and transmits the first type of data to the second network node according to the first protocol, and wherein the third network node lacks support for transferring the second type of data;
- requesting the second type of data from a memory that is external to the first, second, and third network nodes, wherein the second type of data does not correspond to any of the data fields defined by the first protocol;
- and
- obtaining the second type of data stored in the memory without requiring updating of the third network node to support transferring the second type of data.
An apparatus in a communications system for providing a first type of data and a second type of data to a second network node that requires the first type of data and the second type of data, the apparatus being configured to:
- receive the first type of data via a third network node using a first protocol, the first protocol defining a set of data fields corresponding to the first type of data, wherein the third network node receives the first type of data from a first network node according to the first protocol and transmits the first type of data to the second network node according to the first protocol, and wherein the third network node lacks support for transferring the second type of data;
- request the second type of data from a memory that is external to the first, second, and third network nodes, wherein the second type of data does not correspond to any of the data fields defined by the first protocol;
- and
- obtain the second type of data stored in the memory without requiring updating of the third network node to support transferring the second type of data.
