An apparatus for enabling transfer of mobile terminal inter-RAT capabilities in a multi-RAT environment from the perspective of the capability provider may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured, with the processor, to cause the apparatus to perform at least receiving an indication of a request for mobile terminal inter-RAT capability information relative to a particular RAT, acquiring the inter-RAT capability information in response to receipt of the indication of the request for inter-RAT capability information, and providing the inter-RAT capability information to a target base station.

Method, apparatus and computer program product for transfer of capability support information in a multi-rat environment

A method, for example, is described in the present application. Such a method can include detecting or establishing a circuit-switched call. The method can also include establishing a voice-over-internet-protocol standby call in parallel to the circuit-switched call. The method can additionally include activating the voice-over-internet-protocol standby call to become an active voice-over-internet protocol call when a handover situation is detected. The method can further include releasing resources of the circuit-switched call when the voice-over-internet-protocol standby call becomes the active voice-over-internet protocol call.

Method of handover of circuit-switched voice call to packet-switched voice call

An apparatus for enabling source identification for single radio voice call continuity (SR-VCC) in relation to a handover between different RATs may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured, with the processor, to cause the apparatus to perform at least receiving an indication of handover between a first radio access technology and a second radio access technology, defining an identity value for source identification associated with the first radio access technology by utilizing a source identification format associated with a third radio access technology, and providing the defined identity value to a network device associated with a target of the handover. A corresponding method and computer program product are also provided.

In accordance with an example embodiment of the present invention, a method comprises receiving at a first network node an inter-radio access technology (RAT) signaling message from a source node, a handover signaling message including inter-RAT handover information including a START packet switched (START PS) value; determining whether the START PS value is reliable prior to handing over to a second network node at least based in part on the source node from which the START PS value is received and inter-RAT handover information reliability indicator; building an inter-RAT handover information reliability indicator to indicate whether the START PS value is reliable and including the inter-RAT handover info reliability indicator in a second signaling message; and forwarding the second signaling message to the second network node.

Methods and apparatus for reliable inter radio access network handover

A method includes, during an ongoing call of a wireless user terminal in one of a circuit switched domain or a packet switched domain, initiating a handover procedure; setting parameters allowing the other domain to determine the actual resources needed to continue the call in the other domain, sending an indication of these parameters towards a network element of the other domain and completing the handover procedure. When the ongoing call is in the circuit switched domain completing the handover procedure results in handing over the ongoing call to the packet switched domain, and when the ongoing call is in the packet switched domain completing the handover procedure results in handing over the ongoing call to the circuit switched domain. For example, the circuit switched domain may be a GERAN network and the packet switched domain may be an E-UTRAN (LTE) network. In the GERAN network the handover procedure may be accomplished at least in part through a Gs interface between a mobile switching center and a serving general packet radio system support node and/or through a Gb interface between a base station system and the serving general packet radio system support node. The handover procedure is accomplished at least in part by signaling conducted over an Sinterface between the serving general packet radio system support node of the GERAN network and the mobility management entity of the E-UTRAN network.

Handover of circuit-switched call to packet-switched call, and vice versa

A method, apparatus and computer program product are therefore provided that may enable a network sending broadcast and/or dedicated priorities to a mobile terminal to also include priorities with respect to a RAT that does not support the priority algorithm. As such, for example, priority parameters for a legacy network that does not support the priority algorithm may be supplied to a mobile terminal to enable the mobile terminal to make cell reselection decisions without running two different cell reselection algorithms in parallel (e.g., a ranking based algorithm and a priority based algorithm). The provided method includes the steps of receiving an indication of a plurality candidate cells with respect to said cell reselection of a mobile terminal; assigning, toward each of said plurality of candidate cells, a priority, wherein at least one candidate cell of the plurality of candidate cells does not support priority based cell reselection; and providing said priorities to said mobile terminal.

Method, apparatus and computer program product for priority based cell reselection in a multi-RAT environment

There is disclosed a method of packet switched handover in a communications system having at least two modes of operation, the method comprising, at a terminal of the system, associating identifiers of each mode of operation, and responsive to a packet switched connection handover to a new mode, allocating the connection from an identifier of the existing mode to the associated identifier of the new mode.

Inter-mode/inter-rat handover

A packet-switched handover from a first cell to a second cell in a cellular network is discussed. Packet-switched services are provided for a mobile station in the first cell based on a set of information relating to provision of packet-switched services and a protocol for handling provision of packet-switched services for mobile stations, said protocol being a protocol between a cell and a respective control network element. In a control network element relating to the first cell a first message is received, which indicates a request for a packet-switched handover for a mobile station. In response to said first message, a second message is sent to the second cell. This second message requests creation of a set of information relating to provision of packet-switched services for the mobile station in the second cell, and the second message belongs to said protocol for handling provision of packet-switched services for mobile stations.

Packet-switched handover

The problem of synchronization of the handover of the CS and PS resources to the same target cell during DTM handover is solved without affecting the performance of the CS handover. The mechanism of synchronizing the handover of the PS and CS resources is supported by the following functions: (1) resource indications on the CS and PS handover signalling to indicate to target cell network nodes that the CS and PS handover is ongoing at the same time for the same MS; (2) allocated resources indications on the CS and PS handover signalling to indicate to the source cell nodes that there are resources available in the target cell for CS and PS resources; (3) management of the synchronization of the CS and PS handover in the source and target cell.

Combined handover of the circuit-switched (CS) and packet-switched (PS) resources

The present invention relates to identifying resources allocated in a cellular network for a mobile station for packet-switched services. A first identifier is used for identifying a mobile station, and a second identifier is used for identifying resources allocated for packet-switched services for the mobile station. When a mobile station is entering or has entered a second cell from a first cell, a value of a first type for the second identifier is determined. The first type of the second identifier is for use in both the first cell and the second cell for transmitting packet-switched data between the cellular network and the mobile station.
