Abstract
A method of routing control information and bearer traffic in a packet network. When a wireless communication device has established a connection in a coverage area serviced by an Access Network Controller (ANC) and a Serving Node and roams into an area serviced by a new ANC and a new Serving Node, the present invention routes control information to and from the device through the anchor Serving Node (Serving Node through which the connection was established). Bearer traffic is routed to and from the device through the ANC and Serving Node serving the area in which the wireless communication device is located.
Claims8
In infrastructure equipment comprising a gateway node, a first access network controller and a first serving node serving a first coverage area and a second access network controller and a second serving node serving a second coverage area, a method of routing control information and bearer traffic received from a wireless communications device when the wireless device moves from the first coverage area to the second coverage area, the method comprising the steps of:
- receiving control information and bearer traffic in the second access network controller from the wireless communications device;
- transmitting the control information from the second access network controller to the first serving node, wherein the first serving node is the node through which a current connection was established;
- and
- transmitting the bearer traffic from the second access network controller to the gateway node.
In infrastructure equipment comprising a gateway node, a first access network controller and a first serving node serving a first coverage area and a second access network controller and a second serving node serving a second coverage area, a method of routing control information and bearer traffic to a wireless communications device when the wireless device moves from the first coverage area to the second coverage area, the method comprising the steps of:
- transmitting control information from the gateway node to the first serving node;
- transmitting the control information from the first serving node to the second access network controller;
- transmitting the bearer traffic from the gateway node to the second access network controller;
- and
- transmitting the control information and bearer traffic to the wireless communication device.
