Abstract:
A method and apparatus for providing mobile switching center based services over a packet switched network is described. An interface between a mobile station and a packet mobile switching center is provided. The interface is used to transfer control plane information and user plane information between the mobile station and the packet mobile switching center over the packet switched network. A packet mobile switching center for a circuit switched network is also described. In one embodiment, a network controller handles control plane information from a packet switched core network and an interworking unit handles user plane information from the packet switched core network.
Abstract:
A method of determining a domain mode for a mobile station is described. A first domain mode is determined. A determination is made whether to rove from the first domain mode to a second domain mode according to predefined roving criteria. A method of performing Packet Mobile Switching Center discovery for a mobile station is also described. A Fully Qualified Domain Name is derived based on a cell identifier of a current cell. The derived Fully Qualifed Domain Name is used to determine an Internet Protocol Address of a Packet Mobile Switching Center
Abstract:
The invention relates to a method for handing over a call of a mobile entity that is circuit switched attached via a Mobile Switching Center MSC (120) to an I P Multimedia Subsystem IMS, wherein the mobile entity (100) is registered at the IMS. According to the invention, either the MSC or a media gateway act as application function towards a PCRF with the correct IP address of the media gateway.
Abstract:
A VoLGA Access Network Controller, VANC (602), a User Equipment (604), and methods are described herein for providing security to Voice over Long-Term Evolution via Generic Access, VoLGA, traffic.
Abstract:
A method and apparatus for providing both Mobile Terminated, MT, and Mobile Originated, MO, circuit switched (CS) services such as Short Message Service, SMS, services in networks utilizing CS Fallback and CSoLTE-I architectures. An extended SGs interface referred to as SGs+ (63) is implemented between a Mobility Management Entity, MME, (64) in an SAE core network (11) and a Mobile Switching Center Server, MSC-S, (61). The SGs+ interface supports transmission of upper layer CS packet data units while utilizing either connectionless or connection-oriented Signaling Connection Control Part, SCCP, operation. The non access stratum, NAS, signaling support between the User Equipment, UE, (27) and the MME (64) is extended to provide support for both MT SMS and MO SMS service.
Abstract:
In order to prevent unauthorised use of an unlicensed access network connection (300) to access services in a mobile communications network (20), it is proposed to associate a permanent identifier with an established secure connection between a mobile terminal (1) user and an unlicensed network controller (303). The permanent identifier is obtained by the unlicensed access network (300), specifically an unlicensed network controller (303) in this unlicensed access network, when the secure connection with the mobile terminal is established. Any subsequent attempt by the user to solicit services from the core network (20) over this established secure connection will fail unless the user supplies either this permanent identifier or an identity, such as a temporary identifier, that is associated with the permanent identifier. More specifically, such an attempt results in the established secure connection being terminated.
Abstract:
A method for improving session continuity for a terminal (204`) in a serving communication network (202`) distinct from a home communication network (200`) of the terminal (204`), wherein the serving communication network (202`) comprises a session transfer node (208`) for transferring sessions each comprising signaling data and media data from a first access network (210`) of the serving communication network (202`) to a second access network (212`) of the serving communication network (202`) comprises the following: Routing signaling data of a session of the terminal (204`) between the first access network (210`) and the home communication network (200`) via the session transfer node (208`) in the serving communication network (202`), receiving a session transfer request requesting the transfer of the session from the first access network (210`) to the second access network (212`) for the terminal (204`), and transferring the session from the first access network (210`) to the second access network (212`), and routing the signaling data of the session of the terminal (204`) between the second access network (210`) and the home communication network (200`) via the session transfer node (208`).

Abstract:
The basic concept of the invention is to expand the capabilities of the MSC Server enhanced for SR-VCC and of the SCC AS to support a "session transfer revocation" procedure. To allow for such procedure it is envisaged that a MSC-Server enhanced for SR-VCC being involved in a Handover procedure for a call from a source RAN, e.g. E-UTRAN / UTRAN HSPA, to a target RAN, e.g. GERAN / UTRAN CS, sends an indication that a session transfer for said call should be performed towards the target RAN. Once the MSC-Server receives from a mobility management entity, such as MME or SGSN, of the source RAN an indication that a relocation request having initiated the session transfer indication is canceled, the MSC-Server may send an indication that the session transfer should be cancelled towards the SCC AS in the IMS which has performed the session transfer.
