Description

Paging information transmission method between cdma2000 1x and HRPD network

technical field

The present invention relates to code division multiple access 2000 1x (hereinafter referred to as cdma2000 1x) and high-speed packet data (hereinafter referred to as HRPD) dual-mode access terminal (hereinafter referred to as HAT) switching mechanism between the two networks, particularly through the cdma2000 1x network Short Message Service (hereinafter referred to as SMS), a mechanism that transmits HRPD paging information to HAT and notifies HAT in cdma2000 1x network service state to switch to HRPD network to receive services.

Background technique

In practical applications, HRPD networks often appear in the form of joint networking with cdma2000 1x. Usually, cdma2000 1x networks are used to provide voice and low-speed data services, and HRPD networks are used to provide data-based services. Users use dual-mode terminals to connect enter. Logically, the cdma20001x network and the HRPD network are two mutually independent networks, and current commercial networks do not support information exchange between the two networks at the network side. What is happening to one network is invisible to another network. Therefore, in order to prevent the terminal from missing the paging information from either the cdma2000 1x network or the HRPD network, the HAT usually uses the method of listening to the two networks in turn, that is, the HAT frequently switches between the two networks at a specific frequency to listen to the paging information. Paging messages from the two networks.

Under the existing network, because the cdma2000 1x network and the HRPD network are two independent networks, there is no information exchange except that the packet data core network can be shared. However, incoming calls happen randomly on the two networks. In order not to miss the paging information on either network, the HAT needs to frequently switch between the two networks to listen to the paging information of the two networks. The working module will inevitably cause a large increase in the power consumption of the HAT and shorten the standby time of the HAT. The standby time is one of the most sensitive quality indicators for users. On the other hand, when the HAT is in the service state of the cdma2000 1x network, because the HAT does not search the HRPD network, it cannot know the paging information of the HRPD network, and may miss the business with higher priority from the HRPD network.

Contents of the invention

In order to solve the above problems, the purpose of this invention is to provide a HRPD paging information transfer method between cdma2000 1x and HRPD network, reduce HAT switching times between the two networks, can set up the connection link between the two networks, and pass the link, which transmits the incoming call information of the HRPD network to the cdma2000 1x network. In this way, the HAT can only listen to the cdma2000 1x network to know the paging information of the two networks, and only transfer to the HRPD network when receiving HRPD incoming calls or sending and receiving necessary HRPD information.

In order to achieve the above object, a paging information delivery method between cdma2000 1x and HRPD network, comprising steps:

a. Establish a connection path between the service server or similar network elements in the HRPD network and cdma2000 1x;

b. The service server or similar network elements in the HRPD network send service arrival information to the cdma2000 1x network;

c. The cdma2000 1x network notifies the HAT of the service arrival information;

d. After the HAT receives the HRPD service arrival information, it switches to the HRPD network;

e. After the HRPD service ends, the HAT switches back to the cdma2000 1x network.

The present invention provides a paging information transmission mechanism between HRPD and cdma2000 1x network based on SMS or paging message, which solves the problem of frequent switching of HAT between the two networks, thereby effectively increasing the standby time of HAT. At the same time, since HRPD service options and caller information are defined in the short message or paging message used to transmit HRPD paging information, the problem that the HAT cannot know the HRPD service type and caller information under the cdma2000 1x network is solved, which is convenient User's choice of service. Even when the HAT is in the service state of the cdma2000 1x network, the paging information of the HRPD network can also be sent through SMS, which also solves the problem that the HAT cannot obtain the paging information of the HRPD network when the HAT is in the service state of the cdma2000 1x network .

Detailed ways

The invention mainly includes four parts: newly added link between cdma2000 1x/HRPD two networks, HRPD network service server equipment requirements, HAT equipment requirements, cdma2000 1x network equipment requirements.

1. New link between cdma2000 1x/HRPD two networks

There are two ways to deliver HRPD paging information to the HAT.

Method 1: SMS notification method

A link is established between the service server of the HRPD network and the short message control center (hereinafter referred to as SMC) of the cdma2000 1x network to transmit the service arrival message in the HRPD network. The service arrival message will be transmitted according to SMPP (Short Message Point-to-Point Protocol) in the cdma2000 1x network.

The cdma2000 1x/HRPD network structure after the connection link is established is shown in Figure 1.

Method 2: Paging message notification method

A link is established between the service server of the HRPD network and the mobile switching center (hereinafter referred to as MSC) of the cdma2000 1x network to transmit the service arrival message in the HRPD network. This link can refer to the interface between the base station controller (hereinafter referred to as BSC) and MSC in the cdma2000 1x network, and can support the transmission of the base station service request (hereinafter referred to as BS Service Request) message, and the BS Service Request is used to carry the HRPD service arrival information .

The cdma2000 1x/HRPD network structure after the connection link is established is shown in Figure 2.

2. HRPD network service server equipment requirements

In order to realize the transfer of paging information between the two networks, it is necessary to modify the HRPD network equipment, and the network element mainly involved is the service server. The service server is mainly responsible for user management, service establishment, billing, service authentication and other functions in the HRPD network. During the service establishment process, after the service server completes the authentication of the calling user and the called user, it will send a paging message to the called user to notify the user to establish a service connection.

In addition to retaining the previous functions, the transformed business server needs to add the following functions:

1) The HRPD network and the cdma2000 1x network may use different user IDs. For HAT users, the service server needs to establish a mapping table for the user IDs of the two networks. In order to support multiple HRPD services, the mapping table may include multiple HRPD user identities.

2) After the service authentication is completed, it is necessary to send the HRPD service arrival information to the HAT through the 1x network.

If it is sent by short message, the HRPD network service server needs to construct a paging notification short message that meets the requirements of the 1x network and send it to the SMC in the 1x network. The transmission of the paging notification short message shall follow the SMPP protocol. If it is sent by paging message, the HRPD network service server needs to construct a BS Service Request message that meets the requirements of the 1x network and send it to the MSC in the 1x network.

The above paging notification short message or BS Service Request message should include the HRPD service type and the user ID under the cdma2000 1x of the called user and the calling information, and the cdma2000 1x user ID is searched by the service server according to the HRPD user ID of the called user The two-network user ID mapping table is obtained.

3) In order to facilitate HAT judgment, the service type should also be placed in the paging notification short message (corresponding to the short message mode) or BS Service Request message (corresponding to the paging message mode), and pass the service type parameter field in the short message or The service option (Service Option) carried in the BS Service Request message. Different service type values can be defined for different types of HRPD services; if short messages are used, a service type value can also be defined to uniformly identify HRPD services, and then the specific service type identification can be defined in the SMS content.

4) In order to reduce the transformation to the cdma2000 1x network, if the short message mode is adopted, the interface between the service server and the SMC should follow the interface standard between the short message entity and the SMC in the cdma2000 1x network; if the paging message mode is adopted, The interface between the service server and the MSC should follow the interface standard between the BSC and the MSC in the cdma2000 1x network.

3. HAT equipment requirements

In order to realize the transfer of paging information between the two networks, in addition to the HAT having to have the function of communicating with the cdma2000 1x network and the HRPD network respectively, the operation of the HAT also needs to add the following requirements:

1) When the HAT is in the idle state, it resides in the cdma2000 1x network, only when it receives the HRPD service notification short message or the paging message indicating the arrival of the HRPD service and needs to send and receive the necessary HRPD information (such as receiving new system information or performing location registration), the HAT will automatically switch to the HRPD network.

2) When the HAT is in the state of voice call and data communication in the cdma2000 1x network, if there is an HRPD service notification short message arrival, the HAT will refer to the priority of the HRPD service and perform related operations according to the operator's regulations, such as notification users or switching networks, etc.;

When the HAT is in the data communication state in the cdma2000 1x network, if there is a paging message indicating the arrival of the HRPD service, the HAT will also refer to the priority of the HRPD service, and perform related operations according to the operator's regulations, such as notifying the user or switching networks, etc.;

3) The above operations do not require user participation, and HAT will automatically complete them.

4. cdma2000 1x network equipment requirements

The cdma2000 1x network needs to add the following functions to ensure the effective transmission of HRPD service notification short messages:

1) MSC, base station system (hereinafter referred to as BSS) and other equipment in the cdma2000 1x network should support the newly defined service type value in the short message to indicate the HRPD service;

2) In order to ensure the real-time nature of HRPD service notification information, cdma2000 1x network should assign higher priority to HRPD service notification short messages.
