Method for caching and paging data

Abstract

The invention discloses a data caching and paging method. A base station caches data of a network side in a data connection point of a registration area in which an access terminal is located, the data connection point sends a paging request to the access terminal by a session reference network controller and an access network, the access terminal responds to the paging request and establishes a connection with the access network, and the data connection point sends the data to the access terminal by the access network. In the method, the data of the network side are cached in the corresponding data connection point of the registration area by judging the registration area in which the access terminal is currently located; the data connection point sends the paging request to the access terminal by the session reference network controller and the access network, the access terminal responds to the paging request of the access network and establishes the connection with the access network; and the data connection point sends the data to the access terminal by the access network, thus reducing the paging delay, and avoiding that the data of the access terminal occupies memory space on the access gateway.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for data buffering and paging. Background technique [0002] UMB (Ultra Mobile Broadband, Ultra Mobile Broadband) is the evolution of cdma (Code Division Multiple Access) 2000 access technology. Many technologies of UMB air access can greatly improve the performance of cdma2000 access technology, and lay an essential foundation for users to provide more wireless multimedia services with higher requirements. [0003] UMB systems such as figure 1 shown. When the access terminal enters the idle state, if the network side has data to be transmitted to the access terminal, the network side needs to cache the data, and the data on the network side is usually cached in the access gateway. The access gateway then initiates a paging request to the session reference network controller via the data connection point. The session reference network controller initiate...

AI Technical Summary

Problems solved by technology

Therefore, the data of all access terminals under the access network needs to be cached in the access gateway, which requires a large amount of storage space on the access gateway

[0006] Second, the paging delay is large

After that, the data of the access gateway can be sent to the access terminal. This process requires 5 signaling interactions between network elements, resulting in a large paging delay.
