Embodiment Construction

[0032] Embodiments herein describe MME / MSC enhancements for reverse SRVCC.

[0033] figure 1 A communication network 100 is shown in which embodiments herein may be implemented. In some embodiments, the communication network 100 may be adapted for one or more radio access technologies, such as Long Term Evolution (LTE), LTE-Advanced, Wideband Code Division Multiple Access (WCDMA), Global System for Mobile Communications (GSM), or any other 3rd Generation Partnership Project (3GPP) radio access technology.

[0034] The communication network 100 comprises a base station 103 serving a cell. The base station 103 may be a base station, such as a NodeB, eNodeB or any other network element capable of communicating with the user equipment 101 over a radio carrier. In this case, the user equipment 101 is able to communicate with the first network node 110 via a radio carrier.

[0035] User equipment 101 may be any suitable communication device or computing device having communicati...

Abstract

Embodiments herein relate to the use in a Mobility Management Entity (called MME) (201) for enabling communication between a Circuit Switched (called CS) network (100a) and a Packet Switched (called PS) network (100b) The switching method of the service. A user equipment (101) is located in a CS network (100a) and has a communication service in the CS network (100a). By providing communication between the MME and the Mobile Switching Center MSC server 203, the handling is improved.

Description

technical field [0001] In general, embodiments herein relate to Mobility Management Entities (MMEs) and methods in MMEs. More specifically, embodiments herein relate to enabling handover of communication services between a Circuit Switched (CS) network and a Packet Switched (PS) network. Background technique [0002] In a typical cellular network (also known as a wireless communication system), user equipment (UE) communicates with one or more core networks (CN) via a radio access network (RAN). [0003] A user equipment is a mobile terminal through which a subscriber can access services provided by the operator's core network as well as services outside the operator's network (access to which is provided by the operator's RAN and CN). The user equipment may be, for example, a communication device, such as a mobile phone, a cellular phone, or a laptop computer with wireless capabilities. A user equipment may be a portable, pocket, hand-held, computer built-in or vehicle-mo...
