Abstract

The invention discloses a method for transferring paging from 1x network in a high-speed packet data network. The Secondary Color Code mechanism is applied to this invention, so that the AN registered by the MS/AT sends A13-paging to other ANs around it. The call request message is used to page the mobile phone through these ANs.

Description

A method for delivering paging of 1x network in high-speed packet data network

technical field

The present invention relates to the mutual operation between HRPD network (high-speed packet data network) and 1x network (cdma2000, single-carrier network) in communication field, especially relates to in HRPD network and 1x network double network coverage area, will come from the mobile phone of 1x network A method for timely and efficiently transmitting paging in the HRPD system.

Background technique

Currently, regarding the interoperability between the HRPD network and the 1x network, especially when it comes to transferring the paging terminated by the mobile phone from the 1x network in the HRPD system, the prior art adopts the following methods:

When the IWS (interactive solution) is in the PCF (packet control function), as shown in Figure 1, the process is specifically:

101. The MSC (1x switch) discovers a voice call from an MS/AT (dual-mode terminal) within its service area. The MSC sends a paging request (Paging Request) message to the HRPD PCF and one or more 1x BSs (1x base stations) within the paging area of the AN (access network) within which the MS/AT can reach. The MSC starts a timer T ₃₁₁₃ for each paging request message. The paging request message may contain a "virtual paging indicator (VPI)", indicating that the 1x BS should prepare to receive a paging response (Paging Response) message from the MS/AT.

102. The HRPD PCF sends an A14-1x service page (A14-1x Service Page) message, and starts a timer T _1xsp14 . The message includes a general page message (General Page message).

103. The HRPD AN sends an A14-1x Service Page Ack message to the PCF, and stops the timer T _1xsp14 .

104. The HRPD AN sends a general paging message to the MS/AT.

105. The MS/AT tunes to the 1x system, and sends a page response message (Page Response message) through the 1x access channel.

106. The 1x BS constructs a paging response message according to the above response message and puts it in a complete layer 3 message (Complete L3Info) and sends it to the MSC. If the paging request message contains a "flag" information element, the 1x BS shall place this information element in the paging response message. MS/AT is registered in 1x system by default. The MSC stops all timers T ₃₁₁₃ for the MS/AT.

107. The 1x BS/MSC continues the establishment process of the mobile station being called.

108. The MSC determines that the MS/AT that subscribed to the "Cross Notification" service function has registered in the 1x system, and sends an "Event Notification" message containing the registration event to the HRPD AN, and starts the timer T _event . This step can occur at any time after step '105'.

When IWS is in 1xBS, as shown in Figure 2, the process is as follows:

201. The MSC determines that there is a voice call terminated by the MS/AT within its service area. The MSC sends a paging request message to the IWS-1x BS and starts a timer T ₃₁₁₃ . The message may include the information of the calling user, and may also contain a "virtual paging indication", indicating that the 1xBS should be ready to receive a paging response message from the MS/AT.

202. The IWS-1x BS generates a 1x general paging message and encapsulates it in an A21 interface air interface signaling message (A21-1x Air Interface Signaling) and sends it to the HRPDPCF. IWS-1xBS starts timer T _ack21 .

203. The HRPD PCF sends an A21 interface confirmation message (A21-Ack) to the IWS-1xBS. The IWS-1xBS stops the timer T _ack21 .

204. The HRPD PCF sends an A14-1x service paging message to the HRPD AN, and starts a timer T _1xsp14 . This message includes a general paging message.

205. The HRPD AN sends an A14-1x service paging confirmation message to the HRPD PCF. The HRPD PCF stops the timer T _1xsp14 .

206. The HRPD AN sends a general paging message to the MS/AT. If MSC has included the caller's information in step 201, then HRPD AN includes FN message (feature notification message) in the same HRPD message, and it carries caller's information.

207. The MS/AT tunes to the 1x system and sends a paging response message to confirm receipt of the paging information.

208. The 1x BS constructs a paging response message, puts it in a complete layer 3 information message, and sends it to the MSC. If the paging request message includes the Tag information element, the 1x BS includes the information element in the paging response message. MSC stops all timers T ₃₁₁₃

209. The 1x BS/MSC continues the call establishment process where the mobile phone terminates.

210. The IWS-1xBS sends an A21 event notification message to the HRPD PCF to display that the MS/AT is operating on the 1x network, and starts T _ack21 . This step can occur anytime after step '207'.

211. The HRPD PCF returns an A21 interface acknowledgment message. After receiving the message, the IWS-1x BS stops the timer T _ack21 .

The above process explains how to send the voice paging from the 1x system to the mobile phone through the air interface of the HRPD system when the MS/AT is in the HRPD system, so that it can turn to the 1x system to establish corresponding services.

However, there may be other HRPD ANs on the border of the AN where the MS/AT in the idle or dormant state is located. As the MS/AT moves on the border, there will be a so-called ping-pong effect of back and forth registration between different ANs. In order to effectively contain and reduce this ping-pong effect, promote the paging mechanism of many different AN border areas, and improve the paging success rate of MS/AT, the air interface of prior art HRPD defines the Secondary Color Code (secondary color code) mechanism , it can ensure that an AN has the ability to page MS/AT in the service area of other ANs. This technology has been applied to the packet data service initiated by the HRPD network, but it has not been applied to deliver the voice service paging from 1x on the HRPD network, especially when the MS/AT is in the border area of many ANs in the HRPD network. The 1x voice service paging has not been solved in the current access network technology.
