Abstract

The invention discloses a method for implementing location update registration, which is applied to an overlay network including at least a cdma2000 1x network and an HRPD network. Send a location update request that needs to be in the cdma2000 1x network, and stop scheduling the dual-mode terminal without releasing the HRPD network channel resources occupied by the dual-mode terminal, so that the dual-mode terminal is idle for a period of time, and can perform Location update registration for cdma2000 1x networks. This method enables the dual-mode terminal in the active state to still receive voice calls on the cdma2000 1x network when the location area of the cdma2000 1x network changes, preventing the 1x/DO dual-mode terminal in the active state of the HRPD network from being unable to make calls. The dual-mode terminal cannot be paged due to cdma2000 1x location update.

Description

A method for implementing location update registration

technical field

The present invention relates to location update technology, particularly refers to in the overlay network of cdma2000 1x network and HRPD network, 1x/DO dual-mode terminal carries out the location update registration of cdma2000 1x network under the activated state of high-speed packet data (HRPD) network Implementation.

Background technique

The cdma2000 series includes four standard phases: IS95, cdma2000 1x, HRPD, and 1xEV-DV. Among them, the HRPD network is a pure packet data network and is not used to transmit voice signals in the circuit domain. Therefore, in practical applications, the HRPD network is used in conjunction with the cdma2000 1x network, and the HRPD network can transmit relatively high-speed packet data services. cdma2000 1x data services to provide users with better voice and data services.

When cdma2000 1x network and HRPD network are used together, there are four types of terminals, including IS95 terminal, cdma2000 1x terminal, 1x/DO dual-mode terminal and DO terminal. The HRPD standard stipulates that when the 1x/DO dual-mode terminal is in the active state in the HRPD network, it must be able to receive the paging of the cdma2000 1x network, and it is up to the user to choose whether to answer the voice paging from the cdma2000 1x network. And only when the 1x/DO dual-mode terminal switches the active state data service on the HRPD network to the dormant state, can it answer the 1x voice call, and then switch back to the HRPD network to continue the data service after answering the voice, thus reflecting the idea of voice priority . In the prior art, a standard cdma2000 1x terminal actively initiates a location update request to perform location update by detecting changes in system parameter messages in an idle state, and the update process is a standard process.

In the actual network construction process, since the cdma2000 1x network and the HRPD network have different network characteristics and must operate at different frequency points, when planning the cdma2000 1x network and the overlay network of the network, the size of the coverage area may be different. Therefore, within the HRPD network, there is a situation of crossing cdma2000 1x network location areas. As shown in Figure 1, when the dual-mode terminal moves from position A to position B in the activated state of the HRPD network, the cdma2000 1x location area has changed, and the location needs to be updated in the cdma2000 1x network, otherwise, after arriving at position B Unable to receive cdma2000 1x voice paging.

However, because cdma2000 1x and HRPD use different frequency points, the 1x/DO dual-mode terminal in the active state in the HRPD network cannot update the location of cdma2000 1x, which leads to the fact that the network cannot find Call the dual-mode terminal.

Contents of the invention

In view of this, the purpose of the present invention is to provide a method for implementing location update registration, so that the 1x/DO dual-mode terminal performs location update registration of the cdma2000 1x network when the HRPD network is in an active state.

A method for implementing location update registration, applied to an overlay network comprising at least a cdma2000 1x network and an HRPD network, the method comprising:

A. The 1x/DO dual-mode terminal in the active state in the HRPD network receives the cdma2000 1x network system parameter message, and judges whether the location parameter information in it is consistent with the location parameter information saved by itself. If not, it notifies the HRPD network side, and the terminal needs to Perform location update registration on the cdma2000 1x network, then perform step B, otherwise, return to step A;

B. The HRPD network side stops scheduling the dual-mode terminal; the dual-mode terminal performs location update according to the location parameter information sent by the cdma20001x network, and updates the location parameter saved by itself, and then sends a forward rate application to the HRPD network side, HRPD After receiving the application, the network side resumes the scheduling of the dual-mode terminal.

Before step B, the method further includes: judging whether there is currently a forward data packet being sent to the dual-mode terminal on the HRPD network side, and if so, completing sending the forward data packet; otherwise, directly stopping Scheduling of dual-mode terminals.

The stopping of the scheduling of the dual-mode terminal is realized by stopping the reverse link transmission of the dual-mode terminal.

When the HRPD network side stops scheduling the dual-mode terminal, it does not release the resources occupied by the terminal.

The method further includes: pre-defining the RRI as 111 or 110 as a request indication for cdma2000 1x network location update registration,

Then the notification in step A is realized by sending a message with RRI 111 or 110 to the HRPD network side.

Step A further includes: setting the reverse rate between the dual-mode terminal and the HRPD network to be a fixed value for the network side to receive data correctly.

The reverse rate is fixed at 9.6kbps.

The 1x/DO dual-mode terminal is a terminal with a single transmitter and dual receivers.

The present invention temporarily stops the scheduling of the dual-mode terminal by the HRPD network. During this period, the dual-mode terminal updates the location of the cdma2000 1x network. After the location update is completed, the dual-mode terminal resends the forward rate request and re-participates in HRPD. Business scheduling, returning to the normal business process of HRPD. This method enables the dual-mode terminal in the active state to still be able to receive voice calls on the cdma2000 1x network when the location area of the cdma2000 1x network changes, preventing the dual-mode terminal in the activated state of the HRPD network from being unable to perform cdma2000 1x location The dual-mode terminal cannot be paged due to updating.

Detailed ways

The core content of the present invention is: the 1x/DO dual-mode terminal in the activated state sends to the HRPD network a request that needs to be updated in the cdma2000 1x network location, and without releasing the HRPD network channel resources occupied by the dual-mode terminal, Stop the scheduling of the dual-mode terminal, and make the dual-mode terminal idle for a period of time to update and register the location of the cdma2000 1x network. Here, since the HRPD network only supports high-speed packet data services and does not support voice services in the circuit domain, and its forward channel can be scheduled by multiple users in time division, some non-recurring transmission delays are possible for the HRPD network tolerated. The 1x/DO dual-mode terminal referred to in the present invention is a dual-mode terminal with a single transmitter and dual receivers.

Referring to shown in Figure 2, the method for realizing the present invention specifically includes the following steps:

Step 201, after the 1x/DO dual-mode terminal in the activated state of the HRPD network receives the system message from the paging channel of the cdma2000 1x network, judge whether the location parameter information therein is consistent with the location parameter saved by itself, and if not, execute Step 202, otherwise, return to step 201.

Step 202, the dual-mode terminal sets the reverse rate with the HRPD network to a fixed value, this value ensures that the HRPD network side can correctly receive the reverse rate, after that, the network side defaults to this value until the terminal returns to HRPD again Network, and then apply for the forward rate, and the reverse rate remains at this value;

Step 203, the dual-mode terminal notifies the HRPD network side to carry out the location update registration of the cdma2000 1x network, after the HRPD network side receives the location update registration notification, it judges whether there is currently a forward data packet sent to the dual-mode terminal, If so, continue to send the forward data packets that have not been completely sent to the dual-mode terminal, and then perform step 204; otherwise, perform step 204.

Step 204, after the dual-mode terminal has completely received the forward data packet, it notifies the HRPD network side that it has been completely received, and then stops sending the reverse link; the HRPD network side cannot receive the forward rate request sent by the dual-mode terminal , temporarily stop the scheduling of the dual-mode terminal, and then the dual-mode terminal switches to the cdma2000 1x network for location update.

It should be noted that due to the stop of the reverse link transmission, the HRPD network side cannot receive the reverse data within a period of time after the cdma2000 1x network completes a location update, but during this process, the HRPD network side must retain the dual-mode Channel resources occupied by the terminal. In addition, the complete reception mentioned above can include several situations. The first is that the forward data packet has not been sent completely, but the terminal has correctly received all the data content, and it can be considered as complete reception at this time; the second is the forward data packet. After the data packet is sent, the terminal will just receive all the data content, and it is considered to be completely received at this time; the third is that the forward data packet is sent, but the terminal does not receive the content correctly. After that, the network needs to retransmit , however, it is also regarded as completely received at this time, except that the HRPD network side needs to resend the forward data packet next time.

Step 205, after the dual-mode terminal receives the notification of complete reception, perform the location update registration of the cdma2000 1x network according to the location parameter in the system parameter message sent by the cdma2000 1x network, and update the location parameter information saved by itself, after that, with The fixed reverse rate sends a forward rate request message to the HRPD network side.

Step 206: After receiving the forward rate application message, the HRPD network side re-participates in HRPD service scheduling, and can perform normal data services on the HRPD network.

The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

In the HRPD network, the reverse RRI channel is used to indicate the rate of the current user's reverse traffic channel. This channel and the reverse pilot channel are time-division multiplexed, with 3 bits per frame. Table 1 is the definition about RRI channel.

Data Rate(kbps) RRI Symbol   RRI Codeword 0 000 0000000 9.6 001   1010101 19.2 010 0110011 38.4 011   1100110 76.8 100 0001111 153.6 101   1011010 Reserved 110 0111100 Reserved 111 1101001

Table 1

In Table 1, RRI=110 and 111 are reserved field values, and the present embodiment defines RRI=111 as a request for initiating a location update of a cdma2000 1x network, and of course, RRI=110 may also be defined as the request. When the HRPD network side receives the RRI channel message of RRI=111 sent by the 1x/DO dual-mode terminal, it means that the user requests to initiate the location update of the cdma2000 1x network. Thereafter, the HRPD network side continues to finish sending the forward data packets currently being sent to the dual-mode terminal, and then temporarily stops scheduling the dual-mode terminal, but does not release the resources occupied by the dual-mode terminal. After the dual-mode terminal completes the location update in the cdma2000 1x network, it re-initiates a forward rate request (DRC) on the HRPD network with the minimum reverse channel rate. After the HRPD network side receives the DRC application sent by the dual-mode terminal, it re- The forward data scheduling of the dual-mode terminal is started, and the dual-mode terminal returns to the HRPD normal service process.

Referring to Fig. 3, the specific process of updating and registering the location of the cdma2000 1x network by the 1x/DO dual-mode terminal in the activated state in the HRPD network is as follows:

Step 301, the 1x/DO dual-mode terminal in the active state of the HRPD network performs data service transmission, and the 1x/DO dual-mode terminal is referred to as the dual-mode terminal for short below;

Step 302, the dual-mode terminal regularly receives the paging channel message of the cdma2000 1x network in the active state;

Step 303, the dual-mode terminal compares the position parameter from the system parameter message in the cdma2000 1x network paging channel with the position parameter saved by the current dual-mode terminal itself, if inconsistent, then execute step 304, otherwise execute step 302;

Steps 304-305, the dual-mode terminal sets the RRI to 001, that is, the reverse rate between the dual-mode terminal and the HRPD network is set to 9.6kbps, and then the reverse rate remains at 9.6kbps; then the dual-mode terminal will reverse The rate indicator (RRI) is set to 111, and the HRPD network side is notified to update the cdma2000 1x network location;

After step 306, the access network (AN) of HRPD network side receives this request, judges whether there is the data packet being sent to this dual-mode terminal at present, if there is, then continue to send current data packet to this dual-mode terminal, until After receiving the response that the dual-mode terminal has completely received the current data packet, execute step 307, otherwise, directly execute step 307;

Step 307, AN temporarily stops scheduling the dual-mode terminal, and reserves the channel resources corresponding to the dual-mode terminal for a period of time. At this time, although the HRPD network cannot receive reverse data from the dual-mode terminal, it does not release channel resources.

Steps 308-309, the dual-mode terminal updates the location of the cdma2000 1x network according to the location parameter information sent by the cdma2000 1x network, and after the location update of the dual-mode terminal is completed, it starts sending to the AN of the HRPD network at a reverse rate of 9.6kbps DRC request: After receiving the DRC application from the dual-mode terminal, the AN re-triggers the user's right to participate in scheduling, so that the dual-mode terminal returns to the normal service process.
