处理数据传输的装置及方法
Abstract:
一种通信装置，用来处理数据传输，包含有指令如根据从一网络端接收的至少一承载配置，设定一第一承载及一第二承载；根据一加密密钥及该第一承载的一第一承载识别，将一第一数据流的一第一分组加密为一第一加密分组；在成功地传送该第一加密分组到该网络端前，从该网络端接收一第一无线资源控制信息，其中该第一无线资源控制信息设定该通信装置通过该第二承载传送该第一数据流的至少一分组到该网络端；在接收该第一无线资源控制信息后，通过该第一承载，传送该第一加密分组到该网络端；根据该加密密钥及该第二承载的一第二承载识别，将该第一数据流的一第二分组加密为一第二加密分组；以及通过该第二承载，传送该第二加密分组到该网络端。
Abstract(English):

A communication device of handling data transmission comprises configuring a first bearer and a second bearer according to at least one bearer configuration received from a network; encrypting a first packet of a first flow into a first encrypted packet according to an encryption key and a first bearer identity of the first bearer; receiving a first RRC message from the network before transmitting the first encrypted packet to the network successfully, wherein the first RRC message configures the communication device to transmit at least one packet of the first flow via the second bearer to the network; transmitting the first encrypted packet to the network via the first bearer; encrypting a second packet of the first flow into a second encrypted packet according to the encryption key and a second bearer identity of the second bearer; and transmitting the second encrypted packet to the network via the second bearer.
