Abstract:
Embodiments of an enhanced Node B (eNB) and method for RRC connection establishment for small-data transfers in a 3GPP LTE network are generally described herein. The eNB may receive a small-data RRC connection request message from user equipment (UE) that may include an establishment clause value indicating small-data traffic either with or without mobility. The eNB may send an initial UE setup request message to inform the mobility management entity (MME) that a small-data RRC connection is being established. The eNB may receive an acceptance message from the MME for the small-data RRC connection which may include a reduction of an RRC inactivity timer for fast connection release. The eNB may send an RRC connection reconfiguration message to the UE in response to receipt of the acceptance to establish the small-data RRC connection, the RRC connection reconfiguration message including a measurement information element (IE) when mobility is to be supported.
Abstract:
A device includes a transceiver to receive, from a base station, a physical downlink shared channel (PDSCH) transmission and processing circuitry to classify downlink (DL) subframe types for a set of DL subframes associated with a first uplink (UL) subframe for transmission of a hybrid automatic report request acknowledgment (HARQ-ACK) and perform physical uplink control channel (PUCCH) resources mapping based on the classified DL subframe Types for an acknowledgement transmission associated with PDSCH transmission reception.
Abstract:
Technology for providing peer-to-peer (P2P) content distribution via a P2P applications server is disclosed. In an example, service control function (SCF) module can be operable for P2P content distribution and include computer circuitry configured to host P2P applications server operable to manage Internet protocol (IP) multimedia subsystem (IMS) content distribution between two user equipments (UEs).
Abstract:
Generally discussed herein are systems and methods that include Radio Link Monitoring (RLM) on an Enhanced Physical Downlink Control Channel (EPDCCH) transmission within a Heterogeneous Network (HetNet). RLM can be done without regard to a Physical Downlink Control Channel (PDCCH) quality level. A User Equipment (UE) can be configured to receive the EPDCCH transmission from an Enhanced Node B (eNodeB). A quality level of the EPDCCH transmission can be estimated based upon a BLock Error Rate (BLER) of the EPDCCH transmission. If the quality level is lower than a first threshold value for a first specified number of consecutive periods, a timer can be started. In response to determining the quality level is greater than a second threshold for a second specified number of consecutive periods stop the timer before the timer expires. If the timer is stopped before the timer expires, declare a Radio Link Failure (RLF).
Abstract:
In an embodiment, a server registers a client application installed on a user equipment (UE), and evaluates one or more paging cycle criteria for the registered client application. The server determines to establish a target paging cycle used for downlink paging of the UE by a network component (e.g., an access network component or a core network component) of a serving network based on the evaluation, and the server transmits, to the network component, a request for the network component to transition the given UE to the target paging cycle based on the determination. The network component receives the request and assigns the target paging cycle to the UE as requested.
Abstract:
A method of updating a location information, which represents a physical location of a communication device (2), is generated by a location source (1), and sent from the location source (1) via a location object generating unit (1A, 2A) and a cache unit (3A) to a location consumer (4), comprises caching a first location information (6) in the cache unit (3A), monitoring of a second location information (60) received subsequently to the first location information (6) at the location object generating unit (1A, 2A) by the location object generating unit (1A, 2A) to detect an invalid location information, and, triggered by the detection of an invalid location information (30, 50, 70), sending a location object (31, 51, 61, 71, 81) generated by the location object generating unit (1A, 2A) from the location object generating unit (1A, 2A) to the cache unit (3A), wherein the location object (31, 51, 61, 7, 81) comprises an invalidation information (85-88) indicating that a location information (6, 83) sent prior to the location object (31, 51, 61, 71, 81) is invalid such that, when the location object (31, 51, 61, 71, 81) is received at the cache unit (3A), the cached first location information (6) is discarded by the cache unit (3A).
Abstract:
It is presented a server for forwarding one or more SIP, Session Initiation Protocol, messages. The server comprises a processor and an instruction memory. The instruction memory stores instructions that, when executed by the processor, causes the server to: receive a WebSocket handshake request 5 from a client device, the WebSocket handshake request comprising a SIP service capability indicator for the client device; establish a WebSocket connection; store, in a data memory, service capability data for the client device, the service capability data being based on the SIP service capability indicator; receive a SIP message from the client device; add a header field to 10 the SIP message, the content of the header field being based on the service capability data, resulting in a modified SIP message; and forward the modified SIP message to a SIP application router. Corresponding method, computer program and computer program product are also presented.
Abstract:
Procédé d'émission d'un message par un serveur d'un cœur de réseau IP multimédia, et serveur L'invention vise un procédé d'émission d'un message (M1) par un serveur (4) d'un cœur de réseau IP multimédia (CN) suite à la réception (G10,F10') par ledit serveur d'une requête d'enregistrement (REG2,REG1') d'un terminal (2, 2') auprès du cœur de réseau, ladite requête d'enregistrement proposant une méthode d'authentification prévoyant l'établissement d'un tunnel sécurisé entre le terminal et une entité de raccordement (3) de ce terminal au cœur de réseau, ce procédé d'émission comprenant: ¾ une étape d'identification d'un réseau d'accès (AN) utilisé par le terminal pour s'enregistrer auprès du cœur de réseau IP multimédia; ¾ une étape d'élaboration, en fonction du réseau d'accès identifié, d'une recommandation (RECO) quant à l'établissement ou non du tunnel sécurisé entre le terminal et l'entité de raccordement pour ladite méthode d'authentification; et ¾ une étape d'insertion de cette recommandation dans le message émis par le serveur.
