20130122912 | Selective Radio Bearer - This disclosure relates to a source mobility management node and a method in a source mobility management node for handling a mobility procedure moving a wireless terminal to a target system comprising a target mobility management node, the source mobility management node being configured to be operatively comprised in a cellular system. The method comprises the actions of: sending, to the target mobility management node, a communications message the communications message comprising an information element indicating that there is no active Radio Access Bearer, RAB, or Packet Flow Context, PFC, associated with a bearer context for the wireless terminal. | 05-16-2013 |
20140056235 | Smart 3GDT - A smart 3GDT schema has been disclosed, in detail, a method for controlling the communication of a network system has bee disclosed. The network system comprises a UE, a NodeB, a RNC, a SGSN, and a GW. The UE is arranged to be in communication with the RNC via the NodeB, and the RNC is arranged to be in communication with the SGSN which in turn being arranged to be in communication with the GW for non-3GDT communication of the network system, or the RNC is arranged to be in communication with the GW for 3GDT communication of the network system. In this method, statistics of payload transferred between the UE and the GW has been monitored, and if the statistics of payload within a predetermined time period exceeds a first threshold, and the UE is in the non-3GDT communication, then switching the non-3GDT communication to the 3GDT communication. The present application has also disclosed the SGSN, GW, and the network system adaptive to perform the method. | 02-27-2014 |
20140133431 | SERVICE FREQUENCY BASED 3GDT - A method for reducing the signaling load of a GPRS core network system is provided. The GPRS core network system comprises a first UE, a first RNC, a first SGSN, a first core network node, and a first IP network, where the first UE is arranged to be in communication with the first RNC, where the first RNC is arranged to be in communication with the SGSN for non-3GDT communication of the GPRS core network system or the core network node for 3GDT communication of the GPRS core network system, where the first SGSN is arranged to be in communication with the first core network node, where the first core network node is arranged to be in contact with the first IP network, where one or more service requests originates from the first UE to the SGSN, where the number of service requests to the SGSN is measured. | 05-15-2014 |
20140160938 | METHOD, APPARATUS AND SYSTEM FOR MOVING WIRELESS TERMINALS IN MOBILITY MANAGEMENT SERVING NODE POOL - The invention discloses a method for moving a wireless terminal in a mobility management serving node pool comprising at least a source mobility management serving node and a target mobility management serving node, comprising: initiating, from the source mobility management serving node, a first subscriber context procedure to inform the target mobility management serving node of a move action for the wireless terminal; launching, from the target mobility management serving node, a second subscriber context procedure to obtain a subscriber context for the wireless terminal from the source mobility management serving node, in response to the informing; and establishing a connection between a radio access node for the wireless terminal and a session management gateway node via the target mobility management serving node. An apparatus and a system are also disclosed for the same. With the solution, control plane and user plane traffic for the wireless terminal may be moved with a minimum of payload loss. | 06-12-2014 |
20150148073 | REDUCING SIGNALING LOAD CAUSED BY CHANGES IN TERMINAL LOCATION - This disclosure is directed to a serving node ( | 05-28-2015 |
20150201394 | REDUCING SIGNALING LOAD CAUSED BY CHANGE OF TERMINAL LOCATION - A mobility management node and a method in a mobility management node for reducing signalling caused by changes of location of a radio terminal, which mobility management node is configured to be operatively comprised by a wireless communication system and to operatively manage the mobility of the radio terminal and to operatively communicate with a gateway node acting as an interface between the system and an external network. The method comprises obtaining initial position information; obtaining boundary information indicating a boundary area wherein at least one of a policy or a charging rule is to be applied for the radio terminal; obtaining current position information; determining whether the radio terminal is inside or outside the boundary area; providing mobility information when the radio terminal is outside the boundary area and not providing mobility information to the gateway node when the radio terminal is inside the boundary area. | 07-16-2015 |
20150215768 | REPORT OF SERVICING NETWORK, TIME ZONE AND UCI - The embodiments herein relate to a method in a mobility management node for handling information in a network. The node is associated with a wireless device being served by a serving network. The node obtains information about that at least one of the serving network and a time zone and a UCI, has been changed for the device, and information about that the change has not been transmitted to a SGW. When at least one of the serving network and the time zone and the UCI, has been changed, and information about the change has not been transmitted to the SGW, the node transmits the information about at least one of the changed serving network and time zone and UCI, to the SGW, enabling the SGW to forward this information to a PGW. | 07-30-2015 |
20150215823 | ENHANCEMENT ON VOICE CALL CONTINUITY DURING HANDOVER - A handover of a user equipment (UE) between different radio access networks (RANs). For enhancing voice call continuity (VCC). One method comprises: receiving a request for registering in a first node for mobility management in the target RAN from the UE; if the mobility management for the UE fails to be transferred from a second node for mobility management in the source RAN to the first node, inquiring of a HLR/HSS about a third node for mobility management for the UE in the source RAN, wherein the second node is determined from the request for registering, and the third node is determined based on a correlation between the UE and the third node; and sending to the third node a request for transferring the mobility management for the UE from the third node to the first node. | 07-30-2015 |
