Embodiment Construction

[0015] Various embodiments of the invention provide a method and system for multicasting data in a communication network. A plurality of user equipments (UEs) form a specific UE group. A source UE, as one of the UEs in a particular UE group, sends data to other UEs in the group. The data is routed to a broadcast server in the communication network, which multicasts the data in non-duplicated packets to the specific group of UEs. Data may also be routed through a push server, depending on whether that particular group of UEs can receive said multicast data.

[0016] Before describing in detail specific embodiments according to the present invention, it should be noted that these specific embodiments pertain primarily to combinations of method steps and system components related to multicast data in a communication network. Accordingly, the representation of these system components and method steps, where conventional notation is appropriate in the figures, only shows those sp...

Abstract

A method and system for multicasting data in a communication network (100) to a specific group (120) of user equipment (UEs) including a source UE (102). The method provides for transmitting at least one FlowID to a specific group (120), said transmitting comprising informing said specific group (120) of an IP address and a port number of a broadcast server to allow said UE to operate in said network (100) Establish resources for receiving wireless multicast data. The method also includes allowing (303) said source UE (102) to perform floor control over said specific group (120) uniquely identified in said network (100), said allowing being provided by a push server (112) Offered. Next, the method provides for receiving (304) said data from said source UE (102) in a broadcast server (114) and then multicasting said data to a specific group (120) in the form of non-duplicated data packets.

Description

technical field [0001] The present invention relates generally to the field of communication networks, and more particularly to multicasting data in communication networks. Background technique [0002] As the demand for communication and data transmission grows, there is an increasing demand for multicasting data from a single source user equipment (UE) to multiple UEs. Examples of data that can be transferred include video data, voice data, and data files. Existing services for transmitting data to multiple UEs include Push-over-Cellular (PoC) service, Multimedia Broadcast / Multicast Service (MBMS), and Broadcast and Multicast Service (BCMCS). PoC services enable a user to transmit data to or interact with another user or group of users. In a group, only one user at a time is allowed to send data while other users receive data. Data transmission over PoC services requires duplication of data packets at every level in the communication network. Therefore, PoC services ar...
