Device and Method for information about PLMN ID

A mobile station (110) for use in a Radio Access Network, RAN (102), connected to a core network (101) in which there is one or more Public Land Mobile Networks, PLMNs (103, 104, 105). The mobile station (110) is arranged to select one of said PLMNs (103, 104, 105), and is arranged to communicate with its RAN (102) by means of Radio Link Control, RLC, data blocks. The mobile station is arranged to include the identity, ID, of its selected PLMN in an RLC data block, and to inform the RAN (102) of the presence of the ID of the chosen PLMN in the RLC data block by means of including a reserved or pre-defined value in the length indication field of the RLC data block.

Method for the determination of a receiver for location information

The invention relates to a method for distinguishing between LOCATION REPORT messages to avoid ambiguities. Therefore, a value of an information element of request type is returned by a radio network controller, depending on an intended receiver of the location information. A control node receiving the information element value analyses said value and determines the receiver depending on the result of said analysis.

Plmn specific implicit reject feature for controlling mobile station service establishment

A method is provided by a network node (122) for restricting access attempts by a plurality of mobile stations (MSs). The network node (122) supports a Multi- Operator Core Network (MOCN) having a plurality of Public Land M obile Networks (PLMNs). The method includes determining that an overload condition is occurring. Responsive to determining that the overload condition is occurring, an Implicit Reject indication is communicated within one or more Access Grant Channel (AGCH) messages or Paging Channel (PCI 1) messages to the MSs identifying that an Implicit Reject feature is active to restrict access attempts to the network" node ( 122). A broadcast message is communicated to the MSs containing information identifying at least one of the PLMNs to which the Implicit Reject feature applies. Any of the MSs registered with the at least one of the PLMNs identified by the information can restrict their access attempts to the network node (122). A corresponding method by a MS and corresponding network nodes and MSs are provided.

Packet data support node and method of activating packet flow contexts during handover

A method and a system for managing signaling peak loads.

En áreas densamente poblados un periodo de tiempo aleatorio o una desviación se agregan con el fin de evitar congestión de señal. El uso del método y sistema descrito reducirá la carga pico de señalamiento en los canales de señalamiento cuando muchos suscriptores cambial del área de Ubicación al mismo tiempo. El método y sistema como se describió en la presente se implementa fácilmente y no requiere recursos de hardware adicionales o configuraciones en el lado de la red.

A mobile station (110) for use in a Radio Access Network, RAN (102), connected to a core network (101 ) in which there is one or more Public Land Mobile Networks, PLMNs (103, 104, 105). The mobile station (11 0) is arranged to select one of said PLMNs (103, 104, 105), and is arranged to communicate with its RAN (102) by means of Radio Link Control, RLC, data blocks. The mobile station is arranged to include the identity, I D, of its selected PLMN in an RLC data block, and to inform the RAN (102) of the presence of the ID of the chosen PLMN in the RLC data block by means of including a reserved or pre-defined value in the length indication field of the RLC data block.

A method transferring voice calls

In a method and system for transferring a voice call in the packet switched domain to a system supporting both packet switched and circuit switched voice calls, target system, i.e. the system to which an ongoing voice call is transferred is in control of deciding if an ongoing voice call in the originating system should continue in the circuit switched domain or the packet switched domain. In addition the system is enabled to reserve resources in the system to receive the voice call before handing over the voice call.

Improved acquisition of information for a radio access network

Mtc service activation

An MTC device activates an MTC service by first performing an MTC device attachment procedure to attach to a mobile communication network. After the MTC device is attached to the mobile communication network, the MTC device activates a packet data protocol context for the MTC device with the mobile communication network. After the packet data protocol context is activated, the MTC device activates an MTC service with an MTC server.
