Problems solved by technology

When a voice concurrent data call is established and enters the PPP negotiation stage, if the user keeps talking or is in a very noisy environment, the voice frame is always a full-rate frame, and the voice service will occupy all the logical channel space, so that the logical channel FCH and DCCH are not idle To multiplex data service frames, resulting in data service frames during PPP negotiation with a terminal such as a mobile phone cannot be sent to the terminal during the data service call establishment phase, resulting in the failure of concurrent voice and data service calls

Embodiment Construction

[0036] The basic idea of ​​the present invention is: in the voice concurrent data service call establishment stage, the data service frame is preferentially multiplexed on the logical channel, and after the concurrency is successful, the voice frame is preferentially multiplexed on the logical channel to improve the call success rate of the voice concurrent data service .

[0037] The method of the present invention will be described in detail below by taking the logical channel FCH frame format PDU Type1 of the MAC layer as an example. On the FCH, the main service data block multiplexes the voice frame, the secondary service data block multiplexes the data service frame, and the signaling service data block multiplexes the air interface signaling.

[0038] The method for realizing voice concurrent data call provided by the present invention, such as Figure 4 As shown, the method includes the following steps:

[0039] Step 401: the multiplexing sublayer of the SDM judges wh...

Abstract

The present invention discloses a method and a device for implementing service simultaneous voice and data (SVD). At a stage of building SVD calling traffic, a data service frame is preferably multiplexed in a logical channel when PPP negotiation is not completed, forward signaling exists, a voice frame has a full rate and the data service frame exists; and otherwise, the voice frame is preferably multiplexed in the logical channel. The method and the device in the present invention can improve the success rate of the SVD calling and ensure convenient operation for users.

Description

technical field [0001] The invention relates to voice concurrent data technology, in particular to a method and device for realizing voice concurrent data in the CDMA2000 system. Background technique [0002] In addition to supporting basic voice services and data services, the CDMA2000 system also supports concurrent services. Concurrent services refer to supporting two or more services in the same call, for example, concurrent voice services and data services, or data services and Data business concurrency, etc. The protocol standard of CDMA2000 Release A supports concurrent voice service and data service. Generally speaking, it is a service that allows users to make phone calls while surfing the Internet. That is, when the terminal and the packet data exchange domain have data transmission, they can communicate with another The user performs voice communication; or, while performing voice communication with another user, a connection with the packet data switching domain...
