Abstract
The present invention enables a network operator to select a gateway that provides desirable operational parameters to access a network node function in a network node requested by a client. A network service provider detects what service a client device is requesting or using and selects a gateway (e.g. PDN-GW) to deliver the service. The client device is signaled to make a new connection to the network using the selected gateway, e.g. by connecting to the APN associated with the PDN-GW that delivers the service.
Claims10
A method of redirecting a client device from a first gateway to a second gateway for accessing a network node function remote from the client device, wherein the client device is communicatively connected to the first gateway, wherein the client device is communicatively connectable to the second gateway, wherein the second gateway is communicatively connectable to the network node function, and wherein each of the first gateway and the second gateway is a packet data network gateway in a mobile core network, the method comprising:
- intercepting a data signal transmitted from the client device via the first gateway, wherein the data signal comprises data for using the network node function;
- analyzing the data for a pattern associated with the network node function to obtain an analysis result comprising an indication of the network node function;
- selecting a reference to the second gateway based on the analysis result and generating configuration data comprising the reference wherein selecting is further based on one or more properties of the client device, the one or more properties including at least one of cell location, policies, and subscriber information;
- transmitting the configuration data to the client device to configure the client device to initiate a connection to the second gateway and to transmit further data for using the network node function via the second gateway.
