    摘要： Embodiments of the present invention disclose a method and apparatus for service identifying and routing in a multimedia broadcast and multicast service (MBMS) system. The apparatus includes a radio access network equipment (RNC) and a core network equipment (CN) communicating with each other via an Iu connection; CN includes a module for service information transmission which is used to send the identity information corresponding to the service the UE joins to RNC, and RNC includes a module for service identifying and routing which is used to identify the service according to the identity information and determine the routing of the MBMS service in the non access stratum. RNC obtains the identity information corresponding to the service the UE joins through interaction of interface information with CN, identifies the service and determines the routing of the MBMS service in the non access stratum.

    摘要： This application provides a communications method and apparatus, to effectively protect NSSAI at an AS stratum without changing an existing security protocol procedure. The method includes: A terminal device obtains first slice selection assistance information, where the first slice selection assistance information is obtained by encrypting second slice selection assistance information, and the second slice selection assistance information is selection assistance information of a slice to which the terminal device is allowed to access. The terminal device sends a registration request message to an access network device, where the registration request message includes the first slice selection assistance information.

    摘要： A data re-transferring method based on bit transformation is disclosed in the present invention. The key point of the method is to exchange the location of each bit constituting data according to selected transformation modes before implementing QAM during each data re-transferring process. The method further comprises:

    a. presetting the transformation mode representing no bit location transformation at mode 0, modulating and transmitting data with mode 0 during the first data transferring process;
    b. judging whether it is needed to re-transfer the data after completion of the first data transferring process; if not, going to step a to transfer new data; otherwise, further judging whether all of the selected transformation modes have been used, if not, selecting the next mode in turn, if so, selecting the modes in turn from mode 0 again; and
    c. exchanging the locations of bits within the symbol according to the selected mode, then modulating and transmitting the processed data.

    With the method, storage amount can be decreased, balance of reliability of bits within the same data symbol after multiple re-transferring processes can be ensured, in addition, performance of the decoder and reliability of data transmission can be improved.

    摘要翻译： 本发明公开了一种基于比特变换的数据重传方法。 该方法的关键在于在每个数据重新传输过程中实施QAM之前，根据选定的变换模式交换构成数据的每个比特的位置。 该方法还包括：a。 在模式0时预置不表示比特位置变换的变换模式，在第一数据传送过程期间用模式0调制和传送数据; 湾 判断第一数据传输过程完成后是否需要重传数据; 如果不是，则转向a转移新数据; 否则，进一步判断是否使用了所有选择的变换模式，如果不是，则依次选择下一个模式，如果是，则再次从模式0开始依次选择模式; 和c。 根据所选择的模式交换码元内的位的位置，然后调制并发送处理后的数据。 采用该方法，可以减少存储量，保证多次重传过程后同一个数据符号内比特的可靠性平衡，并且可以提高解码器的性能和数据传输的可靠性。
