Abstract: A mobile network entity configured to upon reception of a TFR message forwarding a SM towards a UE in extended idle mode DRX, including a SM-Delivery-Timer/Start-Time indicating the time used in the SM gateway SMSC to supervise the receipt of the TFR message, keep the SM for a specified time if the UE is expected to become reachable before the expiration of the timer, and page the UE. If the UE responds to this paging during this specified time, the mobile network entity configured to deliver the SM to the UE, and if the UE does not respond to this paging during this specified time, or if the UE is not expected to respond within this time, send towards a SM gateway SMSC a delivery failure and set a flag to record that the UE is currently not reachable.

Abstract: In an apparatus of a communication network it is determined whether or not overload protection processing has been requested by a server, the over-load protection processing being performed by dropping messages. In case it is determined that the overload protection processing has not been requested, a message to be sent from a client to the server is processed according to a security protocol. In case it is determined that the overload protection processing has been requested, the message is processed according to the security protocol by adopting the overload protection processing, and a predetermined indication is included in the message processed according to the security protocol by adopting the overload protection processing, in case the message is not dropped.

Abstract: There are provided measures for an enhanced data access technique for user data. Such measures exemplarily comprise detection of unfeasibility of a data access of data of a specified user at a home subscriber server using a mobile subscriber telephone number due to ambiguity of the mobile subscriber telephone number as a user identity and unavailability of an international mobile subscriber identity as a private identity of the specified user, and selection of a process for enabling the data access of data of the specified user at the home subscriber server using the mobile subscriber telephone number on the basis of a necessity of the international mobile subscriber identity as a private identity for the data access of data of the specified user.

Abstract: It is disclosed a method including accepting, after storage of a registration message including first address information received from a first serving entity capable of access technology-independent service control, a de-registration request message including second address information identical to the first address information from a second serving entity capable of access technology-independent service control.

Abstract: Re-assigning Serving Call Session Control Function, S-CSCF, services to a user of a Home Subscriber Server, HSS (200), in a Third Generation Partnership Program, 3GPP, telecommunications network is provided. In the case that S-CSCF services to the user including a registration procedure are previously assigned and access by the user to the S-CSCF services is erroneously lost, the proposal is to provide a method and means to re-assign those services. First, dynamic registration information (204) is uploaded from S-CSCF to the HSS (200) during the registration procedure. Then, the dynamic registration information (204) is stored from HSS (200) to S-CSCF (203) during a re-assignment procedure of the user.

Abstract: 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.

Abstract: A method sets up a link with pre-paging to a called subscriber mobile terminal in a mobile radiotelephone network. A gateway telephone exchange sends a release instruction to the visitor subscriber database of the visited telephone exchange if the gateway telephone exchange has received from the calling mobile terminal, in the time interval since the transmission of the routing request, a message indicating that the setting up of the link is interrupted. On receiving that release instruction, a temporary identification reserved by routing, of resources associated to said identification as well as the resources booked by the search, for the interface between the telephone exchange and the radio subsystem, are released.

Abstract: A switching-oriented signaling load between a switching center (VMSCA) that receives a request for the connection setup and an access mobile switching center (GMSCA) that initiates optimized routing in inter-network fashion that is lower compared to the known method is achieved. The access mobile switching center (GMSCA) enters a destination address (AVMSC) offered by the home network (HPLMN) of a called radiotelephone subscriber (B-MS) or a destination address (AB′) offered by a visited mobile switching center (VMSCB) given call redirection into a message (ANM) that signals the creation of the call connection. It sends the message to the switching center (VMSCA) in order to be interpreted thereat for charging for the call connection. The assigning of a reference number by the originating switching center that implements the charging and the transmission of a separate MAP message (not call destination) by the access mobile switching center are thus no longer necessary.
