Determining a traffic bearer for data traffic between a terminal and a content data source of a content data network

摘要

A method for determining a traffic bearer for data traffic between a terminal (106) of a mobile network (102) and a content data source (116) of a content data network (104) is described. The method comprises sending (126) a service request for data of the content data source (116) from the terminal (106) to a network gateway (110) of the mobile network (102), and determining (132) an edge entity (108) of the mobile network (102). The edge entity (112) is adapted to forward the data traffic between the content data source (116) and the mobile network (102). The method comprises sending (130) a bearer establishment request to a control node (108) of the mobile network (102) for establishing the traffic bearer (389, 589) to the edge entity (112), and directing (154) the data traffic associated with the content data source (116) to the traffic bearer. Therefore a delivery of data between the content data source (116) of the content data network (104) and the terminal (106) may be enabled, which delivery may deploy few mobile network resources and may cause a high user experience of an end user associated with the terminal (116) requesting the data from the content data source (116).

主权项

1. A method performed by a network gateway node in a mobile network comprising:
receiving a request for data from a mobile terminal operating in the mobile network, the request targeting a content data source associated with a content delivery network that is external to the mobile network and including an address of the content data source; determining that the address of the content data source is in the mobile network, thereby indicating that the content data source has an additional interface to the mobile network that is in addition to an interface provided by the network gateway node for reaching external data networks, including the content delivery network; and in response to said determining, generating a bearer establishment request that identifies the content data source and specifies a downlink data traffic filter for implementation in an edge node associated with the additional interface to the content data source, to thereby establish a traffic bearer for delivering the requested data through the edge node rather than through the network gateway node; and sending the bearer establishment request to a control node in the mobile network, thereby initiating establishment of the traffic bearer between the edge node and the mobile terminal, for directing the requested data from the content data source to the mobile terminal via the edge node.
