Embodiment Construction

[0073] In view of the problem that the existing wireless data card can only support one PDP context, resulting in the inability to provide QoS guarantees for multiple different types of applications at the same time, and the problem that different services using different APNs cannot be performed simultaneously, the embodiment of the present invention provides a A method for realizing wireless data card supporting multiple PDP contexts. 3GPP stipulates that mobile terminals such as wireless data cards and mobile phones can establish RABs with multiple PDP contexts, and each PDP context has an independent QoS profile (Profile). If the wireless data card can support multiple PDP contexts, it can By activating multiple PDP contexts, each application uses a single PDP context. For example, the VOIP application uses the PDP context with the QoS service attribute (Traffic Class) as the conversational class (Conversational Class), and the video playback application uses the QoS servic...

Abstract

The invention discloses a realization method for supporting a plurality of PDP contexts by a wireless data card and the wireless data card so as to solve the problems that the wireless data card can support only one PDP context and cannot provide QoS guarantee for simultaneously performed different types of application, and different services using different APNs cannot be simultaneously performed. The method comprises that: when data connection is required to be established, if the connection is first data connection between TE and the wireless data card, unique PPP connection between the TEand the wireless data card is established, a first PDP context corresponding to the first data connection is activated to establish an RAB of the first PDP context, and an IP address of the PPP connection is set as a PDP address of the first PDP context; otherwise, a corresponding service flow template is established for the Nth PDP context corresponding to the Nth data connection, and the Nth PDP context is activated to establish an RAB of the Nth PDP context.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for realizing a wireless data card supporting multiple PDP (Packet Data Protocol, packet data protocol) contexts and a wireless data card. Background technique [0002] With the advent of the 3G (third-generation mobile communication system) mobile communication era, wireless data cards have greater advantages over fixed network access methods due to their high speed and mobility, which has triggered a huge user demand for wireless Internet access. need. [0003] The wireless data card adopts the application mode of TE+MT, among which, TE (Terminal Equipment, terminal equipment) is generally PC (Personal Computer, personal computer / desktop computer) or Laptop (notebook computer), MT (Mobile Termination, mobile terminal) is generally It is a wireless data card or a mobile phone. 3GPP (3rd Generation Partnership Project, the third generation mobile communication stand...
