摘要:
A mechanism to enable roaming queries prior to association/authentication while maintaining the advantages of power saving mechanisms can be implemented. The mechanism can involve requiring a mobile terminal to request the desired information a second time so that the access point may take sufficient time to obtain the desired information. The mechanism can be implemented in conjunction with IEEE 802.11.

Upstream and downstream communication paths are optimized in a configuration where a plurality of gateways are arranged among different networks. A communication system includes a plurality of gateway apparatuses that connect a first network and a second network; a gateway control apparatus that selects at least one of the plurality of gateway apparatuses based on information related to location in the second network of a terminal that communicates with the first network via at least one of the plurality of gateway apparatuses; and path control means for controlling the first network so that a packet(s) having the terminal as a destination passes through the selected gateway apparatus(es).

There is provided a method, a communications device, a vehicle and a computer program for adaptation of operation for communication between communications devices. An application is executed by a first communications device. The application involves data communications with a second communications device. A predicted impact on at least one communications link used for the data communications is acquired. The predicted impact is based on information of current link parameters of the at least one communications link. Operation of the first communications device is adapted based on the predicted impact.

The present invention relates to a solution for handling deferred leg linking in policy and charging rules function in a telecommunications network in relation to handover between two different access technologies. The solution is provided as a nodes, system and a method for handling handover of a user equipment, i.e. UE, (101) in a telecommunications network (100) from one access technology to another access technology, comprising the steps of detecting (203) in a target access gateway, i.e. AGW, (102) that a handover state of the UE is unknown, sending (204) from the target access gateway a gateway control session, i.e. GCS, establishment message to a policy and charging rules function node (105), wherein the message comprise an indication that leg linking of a session is to be deferred until reception of corresponding control signalling from a packet data network gateway (104).
摘要:
The present invention comprises an apparatus and method supporting handover of mobile relay nodes, "RNs" (56), in a wireless communication network (60), in a manner that advantageously differentiates handling of control- and user-plane connections of the wireless communication devices (58) supported by the RN (56). Rather than conventionally anchoring the control-plane connections of relay-connected. UEs (58) at the donor radio base station (54-1 ) supporting the RN (56), the donor radio base station (54-1) includes or is communicatively linked to an anchor node (100) that, from the perspective of the involved control plane entity or entities (70) in a supporting Core Network, "CN" (68), anchors those connections. The anchor node ( 100) facilitates handover between donor radio base stations (54-1, 54-2) such that the control-plane connections are retained at the anchor node (100) while the user-plane connections are switched to the target radio base station (54-2) receiving the RN (5.6) in handover.
摘要:
Provided are a method and device for receiving a multimedia broadcast multicast service. The method includes: UE receiving a specified MBMS which is carried in one or more MBSFN areas to which a source cell where the UE is currently located belongs; after the UE performs cell reselection and resides in a target cell, in the case that the UE determines that one or more MBSFN areas to which the target cell belongs is different from one or more MBSFN areas to which the source cell belongs, the UE acquiring a condition of one or more MBMSs which are carried in the one or more MBSFN areas to which the target cell belongs; and the UE continuing receiving the specified MBMS in the target cell according to the acquired MBMS condition. The adoption of the technical solution provided in the present invention solves the technical problem in the related art that there is no solution to the continuity of receiving the same service when UE moves in different cells among different MBSFNs, thus being capable of keeping the continuity of an MBMS service when the UE moves among different MBSFNs.
摘要:
A collaboration handoff method for seamlessly passing a communication session between devices includes connecting a first device (210) and a second device (216) to enable communication between the first and second devices using an intermediary device (214) to initiate a communication session. A request may be received from one of the first device (210) and a third device (212) to switch to the third device (212) for communication with the second device (216). Communication session data for the first device (210) may be identified at the intermediary device(214). The third device (212) may be connected with the second device (216) within the communication session and the communication session data may be transmitted to the third device (212).
摘要:
A method and apparatus for home Node-B (HNB) mobility with a local IP access (LIPA) packet data network (PDN) connection are described. A target home node-B (HNB) may receive a handover request message from a source HNB to handover a wireless transmit/receive unit (WTRU). A path switch request may be transmitted to a local gateway (LGW) to change a downlink data path towards the target HNB in response to the handover request message. The LGW may act as a mobility management and local mobility anchor for the handover; and informing an HNB gateway (GW) about the handover so that the downlink data path for core network (CN) traffic is modified towards the target HNB.
