Method and system for distinguishing business grade transmission paging message

Abstract

When request for establishing conversation from calling end reaches to the call P-CSCF at called end, message combination device on P-CSCF combines information of type of the call service into request message for establishing conversation. When being reached to PDSN, the said combined message is parsed by message parsing device on the node. Then, the device for packing and sending message on the node sends IP packet of packaging request message for establishing conversation to program control facility (PCF), and informs parsed service type. After obtaining service type, device for identifying service type in PCF informs the service type fill in device to fill in option of representing the service type in message of service request. According to service type from message sent from PCF, AN determines sequence for sending page message for the call. The invention makes AN distinguish whether service is in realtime or not, and send page message in realtime first.

Description

technical field [0001] The invention relates to an IP Multimedia Subsystem (IMS, IP MultimediaSubsystem) in a mobile communication network, in particular to a method and a system for sending paging messages by distinguishing service levels in a mobile communication network. Background technique [0002] With the development of the Internet and wireless services, users' requirements for wireless data services are increasing. While providing rich services, they also have higher requirements for service quality. End-to-end Quality of Service (QoS) support. [0003] As one of the 3D standards, the CDMA2000 network can provide users with a packet bandwidth of 153.6kbps in a wider range. When the CDMA2000 network develops to the EV-DO stage, the user's packet access rate will reach 2-4Mbps. The High Speed ​​Packet Data Rev.A (HRPD Rev.A) system supports transmission on the control channel to distinguish user levels, and prioritizes the transmission of synchronous control informat...

AI Technical Summary

Problems solved by technology

[0013] The P-CSCF only sends the QoS information of the flow to the PCRF, and because the PDSN does not analyze the data packet and forwards it directly, neither the PDSN nor the AN can know the specific QoS requirements before sending an Invite to the called terminal

[0014] In the existing called process, the AN at the called end sends a paging message to the called AT, and the AT responds and establishes an air interface connection. After receiving the signaling message from the application layer, the service type is known, that is, the AN cannot know what it is in advance. business, unable to send paging priority for real-time business

When the control channel is congested in the system, the paging of the real-time service cannot be processed with priority, resulting in a large call establishment delay and poor user experience
