Abstract:
In transmission of paging information from a mobile network to a terminal device (200), the terminal device applies a discontinuous reception cycle to enter a sleep mode. Further, the terminal device determines an advance wakeup time (AW) for leaving the sleep mode. The advance wakeup time (AW) is advanced by an advancement time interval (ΔA) with respect to a start of an active time of the discontinuous reception cycle. At the determined advance wakeup time (AW), the terminal device leaves the sleep mode and starts monitoring the downlink control channel with respect to paging configuration information transmitted by the mobile network. The paging configuration information defines a paging occasion for transmission of the paging information. On the basis of the paging configuration information, the terminal device monitors the paging occasion to receive the paging information from the mobile network.
Abstract:
In data transmission between a mobile network and a terminal device an uplink control channel resource is allocated to the terminal device and to at least one further terminal device. Further, a shared identifier is assigned to both the terminal device and the at least one further terminal device. Using the allocated uplink control channel resource, the mobile network receives a scheduling request from the terminal device. In response to receiving the scheduling request, the mobile network sends an uplink grant. The uplink grant is addressed by the shared identifier to the terminal device and to the at least one further terminal device. Further, the mobile network receives uplink data from the terminal device, which is accomplished on uplink resources indicated by the uplink grant.
Abstract:
Methods in a radio network node (110) and a user equipment (120) as well as a radio network node (110) and a user equipment (120) for providing access restriction information about restricting access to a cell (C1), managed by the radio network node (110), for at least the user equipment (120) are provided. The radio network node (110) encodes a downlink control information message by using a user equipment identifier associated with the access restriction information. Next, the radio network node (110) sends the downlink control information message to the user equipment (120). Next, the user equipment (120) decodes the downlink control information message to obtain the user equipment identifier associated with the access restriction information.
Abstract:
The present invention relates to methods and arrangements for introducing an automatic one-time configuration of the DNS server(s) when a base station gateway, such as an HeNB GW, is deployed, such that the FQDN-to-HeNB GW IP address translation data is proactively configured. This is performed to identify the base station gateway address to which subsequently deployed base stations will be connected. That is, the FQDN-to-HeNB GW IP address translation data for the HeNB IDs of all the HeNBs that may potentially connect to the HeNB GW is proactively configured in the DNS server(s), thereby avoiding frequent and constantly ongoing DNS configuration during normal network operation. This configuration of the DNS allows the eNB to obtain the destination address for an X2 connection without knowing about an eventual HeNB GW, nor the addressing details, such as size/length (or fixed number of bits) of the HeNB GW ID.
Abstract:
The present invention relates to an arrangement, a communication network node and a method of saving radio resources during handover in a communication network system comprising a plurality of communication network nodes (15a, 15b, 15c) communicating with one or more user equipments (18). Each network node (15a, 15b, 15c) is serving at least one cell (19) through and in which the user equipments (18) are moving. The method and arrangement is based on: collection of long term handover statistics (1); selective triggering of Multiple Cell Preparation (2); definition of a Secondary Target Cell List (3); exclusion from the Secondary Target Cell List of cells rarely used (4); preparation of the cells on the Secondary Target Cell List for handover (5).
Abstract:
A method and apparatus for use in a communications network in which a Mobile Node accesses the communications network via a proxy node. The proxy node is arranged to handle mobility signalling on behalf of the Mobile Node. At a mobility anchor function, such as a Local Mobility Anchor, a first Care-of-Address associated with the Mobile Node is registered. When the mobility anchor function receives a registration request to register a second Care-of-Address associated with the Mobile Node, it sends a request message to the proxy node acting on behalf of the Mobile Node. The request message instructs the proxy node to check whether the Mobile Node is reachable using the first Care-of-Address.
Abstract:
The present invention relates to a mobility management control node (111, 113) of a mobile communications network (100) and to a method in the mobility management control node (111, 113). According to the method a 5 gateway (105, 106, 117) is allocated to a bearer (110, 118). The method comprises determining an appropriate gateway for the bearer (110, 118) and obtaining load information indicating a current load of the determined appropriate gateway. If the load information indicates that the current load of the determined appropriate gateway is above a predetermined threshold 10 value of the determined appropriate gateway, a gateway out of the determined appropriate gateway and at least one other gateway is selected based on information associated with the bearer. On the other hand, if the load information indicates that the current load of the determined appropriate gateway is below or at the predetermined threshold value, the determined 15 appropriate gateway is selected. The selected gateway is allocated to the bearer (110, 118).
Abstract:
A technique for relocating a Serving Gateway associated to a User Equipment is described. One method implementation of this technique is performed in a Mobility Management Entity, MME, and comprises the steps of a) triggering, from the MME, a relocation of a source SGW to a target SGW by sending a Create Session Request message to the target SGW, b) receiving, from the target SGW, a Create Session Response message including S1 General Packet Radio Service, GPRS, Tunnelling Protocol, GTP, endpoints of the target SGW, c) updating, from the MME to an Evolved NodeB, eNB, an Internet Protocol, IP, address and a Tunnel Endpoint IDentifier, TEID, of the target SGW, and d) sending, from the MME to the source SGW, a Delete Session Request to delete a session.
Abstract:
The basic concept of the present invention is to utilize the terminal as an auxiliary information collector in networks where the regular network-based information collection is not possible and/or for providing information that complements the information that the network-based Access Awareness Entity collects by itself. The terminal collects information related to the access network directly, through retrieval of explicitly available information, and indirectly, through measurements and statistics. The collected information is delivered to the network-based Access Awareness Entity.
Abstract:
The basic idea of the present invention is to let the base station enter a low-power, low-radiation cycle, the so called “sleep mode”, when there are no UEs using it and to introduce methods to “wake up” the base station from this state when there is a UE in the vicinity which is allowed to access the base station and which may need it on short notice.
