Problems solved by technology

In order to ensure the consistency of business development and the unified scheduling of network resources, it is necessary for the MSC to control the state of the packet data service. However, in the existing technology, the MSC cannot automatically control the packet data service in the function of controlling the packet data service. State transition from active state to sleep state, idle state, etc.
The conversion between the above various states must be done manually, which brings great inconvenience to related business operations

Embodiment Construction

[0022] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 Shown is a schematic message flow diagram of the present invention, as can be seen from the figure, the present invention includes the following steps:

[0024] a. The MSC sends a message to instruct the BS to switch the data service state and process related resources, and the message carries an operation instruction;

[0025] The present invention conforms to the corresponding specification of 3GPP2, and adopts clear command (Clear Command) and clear end (Clear Complete).

[0026] In the standard specification of 3G, it is stipulated that the resources of the BSC related to the voice service and the call flow of the user are uniformly controlled by the MSC. These call flows include voice service, circuit data service, etc., and the flow includes several user packet data states, Such as figure 2 Shown are seve...

Abstract

The invention relates to a method to realize MSC controlling packet data service in CDMA system, including the steps; a, MSC sends information to instruct BS to change data service state and processes relative resources, where the information carries operation instruciton; b, MSC starts up the timer to wait for the response information; c, BS changes the data service state and return the response information; d, after receiving the response information, MSC stops the timer and changes the data service state. It adds the function of MSC controlling packet data service, able to control the change of packet data service between various states.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for realizing the function of MSC controlling packet data services in a CDMA system technical background [0002] In the CDMA protocol specification in the third generation mobile communication field, there are three states of user data service operation: idle / activate / sleep, and can be switched among the three, and the BSC is responsible for controlling the migration of the data service state. In the CDMA2000 system, MSC is responsible for functions such as data service status recording and mobility management. [0003] However, in IS-95 and CDMA20001x, the resources of the BSC related to voice services and the user's call flow (including voice services and circuit data services) are uniformly controlled by the MSC. In order to ensure the consistency of business development and the unified scheduling of network resources, it is necessary for the MSC to contr...
