    • A method for allocating a multicast connection identifier (MCID) to a new multicast/broadcast service (MBS) provided in a wireless network including a plurality of base stations. The method includes: calculating, for a new MBS zone and existing MBS zones, coverage area ratios each based on information regarding the new MBS zone and one of the existing MBS zones, the new MBS zone including a first group of base stations, the one of the existing MBS zones including a second group of base stations; and allocating an MCID to the new MBS based the coverage area ratios; wherein the first group of base stations include ones of the plurality of base stations to transmit data relating to the new MBS, and the second group of base stations include ones of the plurality of base stations to transmit data relating to at least one existing MBS.
    • 一种用于将组播连接标识符(MCID)分配给在包括多个基站的无线网络中提供的新的多播/广播服务(MBS)的方法。 该方法包括:针对新的MBS区域和现有MBS区域,根据关于新的MBS区域和现有的MBS区域之一的信息来计算覆盖区域比率,新的MBS区域包括第一组基站, 包括第二组基站的现有MBS区域; 以及基于所述覆盖区域比率向所述新的MBS分配MCID; 其中所述第一组基站包括所述多个基站中的一个基站,用于发送与所述新MBS相关的数据,并且所述第二组基站包括所述多个基站中的一个基站以发送与至少一个现有MBS相关的数据。

    • A method for providing resource allocation in a communication network includes identifying at least two broadcast zones for receiving broadcast services in the communication network and generating a first index based on a relative relationship among the at least two broadcast zones. The first index includes information indicative of whether a first broadcast zone overlaps with at least one other broadcast zone. The method further includes generating a second index based on the relative relationship among the at least two broadcast zones; assigning at least one identifier to each of the at least two broadcast zones based on the first index and the second index; and enabling data transmissions to the at least two broadcast zones based on the assigned identifiers and using the at least one communication resource associated with the identifiers. The second index may include information indicative of a number of broadcast zones overlapped with the first broadcast zone. Each identifier may be associated with at least one communication resource, with distinct identifiers being assigned to overlapping broadcast zones of the at least two broadcast zones.
    • 一种用于在通信网络中提供资源分配的方法包括:识别用于在所述通信网络中接收广播服务的至少两个广播区域,并基于所述至少两个广播区域之间的相对关系生成第一索引。 第一索引包括指示第一广播区是否与至少一个其他广播区重叠的信息。 该方法还包括基于至少两个广播区域之间的相对关系生成第二索引; 基于所述第一索引和所述第二索引,向所述至少两个广播区域中的每一个分配至少一个标识符; 以及基于所分配的标识符以及使用与所述标识符相关联的所述至少一个通信资源来启用对所述至少两个广播区域的数据传输。 第二索引可以包括指示与第一广播区域重叠的广播区域的数量的信息。 每个标识符可以与至少一个通信资源相关联,其中不同的标识符被分配给至少两个广播区域的重叠的广播区域。

    • The present invention provides a system using label switching techniques to support QoS for mobile ad-hoc networks and its label distributing and switching method. The system includes plural clusters, each having plural mobile nodes. At least one mobile node in a cluster is selected as a routing agent. One routing agent in a cluster is selected as a core routing agent. Each core routing agent is capable of obtaining an unique seed for generating an label L=f(S, i, j)=S×3i×2j to a new LSP, where S is an unique seed that is an unique prime number, except 2 and 3, obtained by the core routing agent, i represents one of different kinds of LSP, and j represents one of different numbers for the same kind of LSP. Through the interconnecting of core routing agents, the virtual backbones can be constructed for bandwidth sharing.
    • 本发明提供一种使用标签交换技术来支持移动自组织网络的QoS及其标签分发和切换方法的系统。 该系统包括多个簇,每个簇具有多个移动节点。 集群中的至少一个移动节点被选择为路由代理。 选择集群中的一个路由代理作为核心路由代理。 每个核心路由代理能够获得一个唯一的种子,用于生成一个新的LSP的标签L = f(S,i,j)= Sx3ix2j,其中S是除了2和3之外的唯一素数的唯一种子, 由核心路由代理获得,i表示不同类型的LSP中的一种,j表示同一种LSP的不同数字之一。 通过核心路由代理的互连,虚拟骨架可以被构造用于带宽共享。
