Problems solved by technology

This will inevitably have adverse effects on the ongoing data services of dual-mode terminals, especially some data services with high real-time requirements, such as VOIP, VT, PTT, etc., resulting in interruption of data services, thereby affecting service quality
In addition, for paging from the 1x network, when the 1x location information of the dual-mode terminal is invalid, if the MSC / MSCe cannot know the current specific location information of the dual-mode terminal in the EV-DO network, the MSC / MSCe may paging not reach the dual-mode terminal, resulting in paging failure

Embodiment Construction

[0026] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] See Figure 4 As shown, the method for paging a dual-mode terminal provided by the present invention mainly includes the following steps:

[0028] Step 401: When an event occurs in the dual-mode terminal in the EV-DO network, AN notifies the MSC / MSCe of the event that the dual-mode terminal has in the EV-DO network. The MSC / MSCe determines that the dual-mode terminal is in the EV-DO network based on the learned event. Status in the DO network;

[0029] Step 402: When there is a paging from the 1x network, the MSC / MSCe determines the way of paging the dual-mode terminal according to the state of the dual-mode terminal in the EV-DO network, and page the dual-mode terminal.

[0030] Wherein, the event that the dual-mode terminal occurs in the EV-...

Abstract

The method comprises: a) when dual-mode terminal has an event happening in evolution-data optimized (EV-DO) network, the access network (AN) informs said event to mobile switch center / mobile switch center emulation (MSC / MSCe); according to the obtained event, MSC / MSCE determines the status of dual-mode terminal in EV-DO network; b) when receiving a paging from 1x network, according to the status of dual-mode terminal in EV-DO network, MSC / MSCe determines the mode of making the paging to dual-mode terminal, and makes paging to the dual-mode terminal.

Description

Technical field [0001] The invention relates to a code division multiple access (Code Division Multiple Access, CDMA) technology, in particular to a method for paging a dual-mode terminal. Background technique [0002] The CDMA 2000 standard is a protocol family, including CDMA 2000 1x and CDMA 2000 1x enhanced-high-speed data (Evolution-Data Only, EV-DO). CDMA 2000 1x can provide voice services and 307.2Kb / s data services within a wireless transmission bandwidth of 1.25MHz. At present, CDMA 2000 1x is quite mature and has been successfully commercialized in many countries and regions; CDMA 2000 1xEV-DO is aimed at data applications. Optimized, it can provide a data rate of up to 2.4Mb / s within a wireless transmission bandwidth of 1.25MHz, and has a very high spectrum utilization. At present, CDMA 20001xEV-DO has also been commercialized on a large scale. [0003] Since most CDMA operators have already built 1x networks, how to introduce EV-DO networks on 1x networks has become t...
