Method and apparatus for keeping PoC continuous connection handling capacity

Abstract

The invention discloses a method and an apparatus for keeping proof of concept (PoC) continuous connection handling capacity. According to the method, a state presentation server receives continuous connection service request information from a PoC client and transmits the continuous connection service request information to a policy and charging rules function (PCRF); the PCRF transmits an internet protocol-control area network (IP-CAN) session continuous connection capacity request corresponding to the user information to a gateway GPRS supporting node (GGSN); the GGSN provides a continuous connection capacity to the user through a service GPRS supporting node (SGSN); and the PoC client adaptively adjust a heartbeat cycle of the presentation server in real time according to a network quality situation, so as to guarantee continuous connection of the PoC client. The embodiment of the invention not only can effectively reduce influence of frequent transmission of a conventional heartbeat packet on a network signaling load, but also can realize packet connectivity initiated by the terminal according to the quality of network in which a terminal side is located, thus guaranteeing continuous connection from both network and terminal aspects and enhancing use efficiency and quality of users.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for maintaining PoC persistent connection processing capability. Background technique [0002] For UMTS (Universal Mobile Telecommunications System, universal mobile communication system), with HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access) and E-DCH (Enhanced-Dedicated Channel, enhanced dedicated channel) Many mobile users like to use packet data services, and they all hope to get a quick response from the network even if there is only occasional data transmission during the long-term online period. [0003] In order to save wireless resources, the network will terminate the connection when it detects that no user data is sent within a period of time. When there is new data to be transmitted, re-establish the connection. The corresponding signaling overhead and delay caused by frequent connection termination and ...

AI Technical Summary

Problems solved by technology

[0010] From the perspective of user experience, of course, the smaller the delay, the more satisfied the user is. The first method is the processing mechanism of the existing mobile communication network, but the processing delay is relatively longest, which cannot meet the delay requirements of PoC. Nor does it have the ability to achieve a persistent connection

The second method, which reduces the overhead of system resources, is a better method in theory, but this technology is only applicable to HSPA+ (High Speed ​​Packet Access, high-speed packet access) network, and requires the existing network and physical layer Upgrade and transformation, poor deployability

The third method has the strongest deployment capability and flexible business development, but if the heartbeat period is too long, the business will be offline. If the heartbeat period is too short, it will cause a lot of signaling overhead, and even cause a signaling storm, resulting in a waste of resources. and UE power consumption, reducing the standby time
