Application relates to establishing signaling connections in communication network. A source radio access network device sends a handover request message to a target radio access network device to initiate a handover procedure for a user equipment from the source radio access network device to the target radio access network device. The handover request message includes information about an original signaling connection parameter. When the UE enters a target cell, the target radio access network device allocates a new signaling connection parameter and sends a handover complete message to a core network node. The handover complete messages carries the original signaling connection parameter received from the source radio access network device and the allocated new signaling connection parameter about the target radio access network device. The inability of the target radio access network device to establish a signaling connection with the core network node in the related art is effectively solved.

The system and method can configure a virtual network for each end user within the communication network using the policy management capabilities based on the user-defined sets of rules and instructions provided by each end user. The user-defined sets of rules and instructions define provisioning and delivery of resources and services provided by the communication network to the end user.

A wireless network for mobile communications has a connectionless framework using native internet protocol (IP). In this connectionless framework, packet routing may be based on user endpoint (UE) physical IP address, which is associated with the prefix of an associated access node (e.g. eNB). In addition to using the connectionless-IP framework for the traffic flow carried by one access point (e.g. eNB) at a time, advanced mobile call processing features, such as carrier aggregation and dual connectivity, are enhanced to leverage the packet-oriented connectionless radio access network and wireless core network architecture by using the SDN architecture and a wireless network specific software-defined network controller.
