| 20090003276 | Access domain selection in a terminal - The present application discloses a system of at least a network element and at least a terminal. The system constituents are configured to provide assistance by the terminal to the network element in terms of access domain selection for at least one of the media channel and the session control channel of an incoming call to the terminal. In this regard, the terminal acquires information about the capabilities of an access network in which the terminal is camping. Upon receiving, at the terminal, an invitation to participate in a call, the terminal analyzes the acquired information about the capabilities of the access network, and optionally or additionally of the IMS network. The terminal responds to the invitation, based on the result of the analyzing, with an indication that indicates a respective access domain to be used for at least one of the media channel and the session control channel of the incoming call. | 01-01-2009 |
| 20090258671 | METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR ENABLING USER CONTROL OF A FALLBACK CAPABILITY FOR CIRCUIT SWITCHED DOMAIN SUPPORT - An apparatus for enabling user control of a fallback capability for circuit switched domain support may include a processor and a memory. The memory may store executable instructions that in response to execution by the processor cause the apparatus to receive a service indication for a service related to a radio access technology not supported by a current serving domain, determine, based on previously stored user defined input, a response to the service indication with respect to conducting a fallback procedure to a radio access technology that supports the service, and execute the response based on a result of the determining. | 10-15-2009 |
| 20110013597 | METHOD AND ENTITIES FOR INTER-DOMAIN HANDOVER - Aspects of the present invention relate to methods and entities involved in enabling and improving inter-domain handover. A PS based RAN such as eUTRAN can identify which potential handover to prepare and which handover to initiate, PS-PS or SR-VCC based on: (1) the UE's SR-VCC capabilities, (2) “SR-VCC indication” from the MME, (3) active VoIP bearer, and (4) target cell capabilities. | 01-20-2011 |
| 20110051691 | CIRCUIT SWITCHED DOMAIN CODEC LIST FOR SINGLE RADIO VOICE CALL CONTINUITY - A Circuit Switched (CS) domain codec list for Single Radio Voice Call Continuity (SR-VCC) is provided An apparatus providing such a list can include prepaπing a list of circuit switched capabilities of a terminal device, sending the list to a network device dunng attachment, receiving the list at the network device, stoπing the list in the network device, sending the list to a second network device, receiving the list at the second network device, and using the list in handing over the terminal device to the second network device. | 03-03-2011 |
| 20110201342 | MINIMIZING LOCATION UPDATE IN CIRCUIT-SWITCHED FALLBACK - A method can include allocating a temporary mobile subscriber identity for a user equipment during a location update procedure. The method can also include allocating, during the allocating of the temporary mobile subscriber identity, a unique network resource identifier value for the whole network element, wherein temporary mobile subscriber identity allocation avoids being location area based. The method can further include providing, to the user equipment, a location area identifier, temporary mobile subscriber identity with the unique network resource identifier value, and an indication to skip location area identifier checking when performing circuit-switched fallback. Certain embodiments of the present invention can thus minimize the LAU by the UE and allow the network not to require perfect alignment of TA and LA. | 08-18-2011 |
| 20110230162 | SRVCC EMERGENCY CALL SUPPORT APPARATUS, SYSTEM AND METHOD - Method and apparatus, including computer program products, are provided for SRVCC emergency call support. The method may include receiving, at a mobility switching center, a first message representing a request to handover an emergency communication session from a first network to a second network. The mobile switching center may obtain a value representing an emergency session transfer number. The mobility switching center may also send a second message to the first network. The second message may initiate handover of the emergency communication session from the first network to the second network. The second message may comprise the value representing the emergency session transfer number. Related apparatus, systems, methods, and articles are Receive Session Continuity Data also described. | 09-22-2011 |
| 20110269482 | MME Name in MAP Insert Subscriber Data Operation - Embodiments of the invention include a method, apparatus, and computer readable medium related to mobility management. The method, apparatus, and computer readable medium may include, at least, receiving, at a network node, a terminating request from a user equipment. The method, apparatus and computer readable medium may further include, in response to receiving the terminating request, performing a restore data procedure, receiving a mobility management entity (MME) name from another network element in response to the restore data procedure, and registering the MME name to the subscriber data associated with the user equipment. The method, apparatus and computer readable medium may then include sending a paging request to the MME indicated by the MME name received from the other network element. | 11-03-2011 |
| 20110319082 | METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR SOURCE IDENTIFICATION FOR SINGLE RADIO VOICE CALL CONTINUITY - 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. | 12-29-2011 |
