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:
The combination of narrowband applications with broadband transport is enabled by combining a first node (330) having narrowband ability with a second node (340) having broadband ability in which call control functionality of the first node is provided to the second node. Both the first node and the second node have connection control funcitonality for switching data information of a given call. However, the broadband second node receives signaling information from the narrowband first node, which has call control functionality, over one or more links to enable the second node to switch a call in accordance with determined call control instructions. The combination of the narrowband first node and the broadband second node results in a hybrid switch that is capable of operating with both synchronous transfer mode (STM) networks and asynchronous transfer mode (ATM) networks.
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 combination of narrowband applications with broadband transport may be enabled by implementing a hybrid switch (HS, 420) capable of operating as a narrowband switch, a broadband switch, and/or a combination narrowband/broadband switch. The hybrid switch may be initially installed/activated as a narrowband switch in order to operate with a network of all or mostly all narrowband switches. Eventually, the hybrid switch may be used entirely as a broadband switching mechanism when operated with a network of all or mostly all broadband switches. In the interim, the hybrid switch may be operated in a narrowband or a broadband mode on a communication-by-communication basis, for example, depending on the capabilities of the node or nodes to be used in establishing a given communication. The hybrid switch may include both broadband (e.g., ATM) and narrowband (e.g., STM) switching components.
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 combination of narrowband applicantions with broadband transport is enabled by combining a first node (330) having narrowband ability with a second node (340) having broadband ability in which the first node has at least call control functionality, and the second node has connection control functionality and associated switching capabilities. The second node may rely on the call control functionality of the first node for traffic handling functions. Communications between the two nodes may be effectuated over first and second links (300) for call signaling information and call data information, respectively. When switching fabric (335, 345) for call data information is present in both of the first and second nodes, incoming calls to either node may be routed as an outgoing call from the other node in order to, for example, switch between broadband and narrowband transport mechanisms.
Abstract:
The combination of narrowband applications with broadband transport may be enabled with a tri-level nodal system in which a narrowband node (e.g., a telecommunications node) may provide switching intelligence to the switching fabric of multiple broadband nodes (e.g., media gateways). the switching intelligence is provided via an intermediate node (e.g., media logic) that emulates a switch interface for the narrowband node and translates circuit-based addresses/routing instructions to packet-based addresses/routing instructions. This translation equates to a mapping of address(es) in a first address space to address(es) in a second address space in order to utilize the address(es) of the second address space for propagating communications on a broadband transport mechanism.

A method and apparatus are provided for providing periodic location updates to a MSC-S in a CS core network providing CS services for a terminal attached to a PS cell of a radio access network such as an LTE radio access network. The method comprises sending periodic location updates from a PCSC in the core network to the MSC-S for as long as the terminal is registered with the PCSC or the PCSC receives location updates from the terminal.
