20080253332 | SELECTIVELY ACQUIRED SYSTEM INFORMATION - A method, apparatus and computer program product are provided that improve mobility procedures between base stations based on rules configurable by the operator that govern both the mobile terminal and the base stations. A method is provided in which a mobile terminal obtains system information from a neighboring base station. The system information is stored at the mobile terminal such that the mobile terminal may thereafter participate in a handover or reselection to a respective neighboring base station at least partially based upon the stored system information, typically without further verification of the system information. If desired, the mobile terminal can further determine if one or more predefined validity criterion is met with respect to the stored system information. If the predefined validity criterion is not met, the mobile terminal can then obtain system information, e.g., updated system information, from the neighboring base station. | 10-16-2008 |
20080268843 | Apparatus, method and computer program product providing priority setting for multi-rat interworking - Apparatus, methods and computer program products operate an electronic device to receive through from a wireless communications network a prioritized list of radio access technologies; to store the prioritized list of radio access technologies in a memory of the electronic device; and to consult the prioritized list of radio access technologies during cell selection and reselection operations. In variants the radio access technologies listed in the prioritized list of radio access technologies can be E-UTRAN, UTRAN or GERAN. In a further variant to consult the prioritized list may mean to compare at least one of a signal measurement and a quality measurement with at least one threshold established for a certain radio access technology appearing in the prioritized list, and to select/reselect to the certain radio access technology only if the at least one of the signal measurement and the quality measurement exceeds the threshold. | 10-30-2008 |
20080280604 | Forbidden neighbor cell list - Mobility in E-UTRAN might not rely on neighbor cell list. In such a case, the user equipment (UE) may be responsible for finding cells and reporting to the network. Consequently signaling load may be increased and also handover (HO) performance can be degraded for the cases in which the target cell proposed by the UE is not good. Certain embodiments of the present invention give the operator some control of the signaling load and HO performance by providing a list of forbidden cells with regard to which the UE does not have to search and report. | 11-13-2008 |
20100165948 | FAST COMBINATIONAL VOICE CALL CONTINUITY FROM LTE TO 2G/3G CS DOMAIN - The invention proposes a method for handing over a session between a source network which provides a first connection type domain and a target network which provides the first connection type domain and a second connection type domain, comprising informing a network node (e.g., a user equipment (UE)), before performing forming a handover from the source network to the target network, a preferred transfer domain in the target network. The invention also proposes a corresponding network node and a network control element. | 07-01-2010 |
20100195621 | METHOD, RADIO SYSTEM, AND BASE STATION - In a radio system having at least one base station that is part of a public mobile network, at least one mobile terminal communicates with the at least one base station, a local breakout service network provides Internet protocol gateway services. A serving base station of a mobile terminal is configured to provide the local breakout service to the Internet protocol gateway while retaining user access control and a remote Internet protocol gateway of a packet core network of the public mobile network for the mobile terminal; to provide information on neighboring cells in which the local breakout service can continue; to make a handover decision based on measurement reports received from the mobile terminal; and to transfer user context data including local breakout service related information to a target base station during handover for providing mobility within the local breakout service area for the mobile terminal. | 08-05-2010 |
20100278161 | SELF OPTIMIZATION OF FORBIDDEN NEIGHBOR CELL LIST - An apparatus, a system, and a method to self-optimize a forbidden neighbor cell list (FNCL). A FNCL includes a list of cells sent to a user equipment (UE). The UE would not report those cells in the list to a network but may be considered by the UE for measurement purposes only. The self-optimization of the FNCL includes building a list of neighbor cells in an autonomous and/or automatic manner, with or without human intervention. | 11-04-2010 |
20100298017 | Closed Subscriber Group Measurement Reporting - An adjacent cell is determined to be a private cell, and then a measurement report of it that includes an identifier for the private cell is sent from a UE to the UE's serving network node. Methods, apparatus and computer readable media storing a program are detailed. In exemplary non-limiting embodiments: the identifier is at least a TA ID for the private cell's CSG network, where the UE receives the TA ID over a broadcast channel/system information of the serving network node; the TA ID may be a short TA ID received over a primary broadcast channel of the serving network node; the identifier comprises the TA ID and either a LI cell ID or a CSG cell ID; and if the UE is not a member of the CSG network it the measurement report only in response to a command received from the serving network node. | 11-25-2010 |
20110269460 | Closed Subscriber Group Cell Identification for Active Mode Mobility - While camped on a first cell with a first access node, it is determined that a second cell of a second access node is a private cell. From information received from a network it is determined that a criteria is satisfied, and conditional on the criteria being satisfied, a unique identifier for a private network of the private cell is decoded. Exemplary embodiments include a method, apparatus and computer readable medium storing a program. In various specific and non-limiting embodiments: being camped on the first cell comprises being in an active RRC CONNECTED state; the information received is broadcast information, the determining is by comparing received L1 ID to a list of locally stored CSG L1 IDs; the received broadcast information comprises a first portion of a TA ID and the criteria being satisfied comprises the first portion matching an entry of a locally stored whitelist. | 11-03-2011 |
20120190335 | Forbidden Tracking Area Optimization For Private/Home Networks - Access verification is adaptively done using an identifier of a first or a second length, by comparing a field of a node address that has the determined first or second length against a locally stored access list. At least the compared field of the node address is either added to a locally stored list of cell selection candidate nodes where the access list is allowed identifiers, or excluded from it where the access list is restricted identifiers. The node identifier is in three sections. The first section is service type, which the UE can use to determine whether or not it is restricted/allowed. The first length is the length of the second section, which is a service area ID of a group of network nodes. The second length is the length of the second section plus the third section, which identifies one node of the group of network nodes. | 07-26-2012 |
20140325597 | ACCESS CONTROL FOR CLOSED SUBSCRIBER GROUPS - A network transmits (broadcasts) an access mode indicator that indicates whether a closed subscriber group CSG network is being operated as open or closed and if it indicates open a user equipment UE that is not a registered member of the CSG is allowed access as a guest member, a user group of the closed subscriber group network, and allowing the user equipment access to the closed subscriber group network as a guest member. The CSG network can provide higher priority services to its registered members by differentiating them over guest members by an indication, received from each UE in its RADIO RESOURCE CONTROL CONNECTION REQUEST message, whether it is registered or a guest. The CSG can also transmit its ID/name for display at the UE so they may select whether and which CSG to join. | 10-30-2014 |
