Description

A method and system for establishing a high-rate packet data network packet data session

technical field

The invention relates to a high-speed packet data network, in particular to a method and system for establishing a high-speed packet data network packet data session.

Background technique

CDMA2000 1x network is currently the CDMA network with the largest user scale, with circuit voice services and low-to-medium speed data services as the mainstays. High Rate Packet Data HRPD (High Rate Packet Data) is optimized for data service applications, also known as CDMA2000 1x EV-DO (EvolutionData Optimized). The reverse link of HRPD version A can reach 1.8Mbit/s, while the forward link can reach the peak rate of 3.1Mbit/s. The key to HRPD's superior performance is that it uses closed-loop rate control and enhanced capacity scheduling algorithms to transmit data to each user at the highest possible rate and in bursts. The modulation method and transmission time selection can be dynamically controlled according to the channel environment, so as to obtain the best effect.

The process for the terminal to establish a packet data session under the HRPD network is:

1. The terminal establishes an HRPD session with the access network AN (Access Network), including allocating UATI and conducting session negotiation;

2. Allocate wireless service channels;

3. The AN establishes an A8 connection with the packet control function PCF (Packet Control Function), and the PCF establishes an A10 connection with the packet data service node PDSN (Packet Data Service Node);

4. The terminal establishes a PPP connection with the PDSN.

HRPD can independently build a wireless mobile data network, and can also be mixed with CDMA2000 1x to complement each other and complete the functional requirements formulated by the ITU for 3G systems.

HRPD network and CDMA2000 1x network have two different connection methods, and the two methods may also exist at the same time.

As shown in Figure 1, the first connection mode is: the access network AN of the HRPD network and the mobile switching center MSC and the base station controller BSC of the CDMA20001x network are connected through the A1/A1p interface, wherein the A1 interface is based on circuit connection, and A1p is based on IP connect. The A1/A1p interface is mainly used to transmit CDMA2000 1x circuit service-related signaling.

As shown in Figure 2, the second connection mode is: the AN of the HRPD network and the BSC of the CDMA2000 1x network are directly connected through the A21 interface. The A21 interface is currently mainly used to transmit information related to the CDMA2000 1x air interface when the terminal is monitoring the HRPD network.

In view of the fact that the 3G business market has not yet fully started, and considering the cost of network construction, the first phase of HRPD network construction generally adopts the scheme of hotspot coverage. In this way, there must be a problem of service switching between CDMA2000 1x and HRPD network at the edge of the HRPD network. At the same time, the same problem also exists in the HRPD network due to the need for load adjustment between the 1x and HRPD network. Therefore, it is necessary to study the seamless handover of services between CDMA2000 1x and HRPD networks, so as to realize the complementary advantages between the two networks and ensure user experience at the same time.

If the terminal can establish a packet data session with the HRPD network while performing services on the 1x network, it will be very beneficial for the seamless handover of services between the 1x and HRPD networks. However, there is no such solution in the current prior art.

Detailed ways

The main idea of the present invention is: while the terminal performs business under the CDMA2000 1x network, the connection between the air interface of the CDMA2000 1x network and the base station controller BSC of the CDMA2000 1x and the AN of the HRPD network completes the establishment of the HRPD network packet data session.

With reference to accompanying drawing 3, be that main process of the present invention comprises:

Step 31: Create a channel on the CDMA2000 1x air interface to carry the information flow between the terminal and the HRPD network.

The 1x air interface channel carrying HRPD information can be established in the following three ways:

A. Using the transmission capability of the current channel, there is no need to establish an additional 1x service channel;

B. The terminal negotiates with the 1x network and applies for adding a new wireless service channel, such as a DCCH channel;

C. The terminal initiates a CDMA2000 1x packet service request to obtain the relevant wireless service channel, but the CDMA2000 1x BSC does not establish an A8 connection with the CDMA2000 1x PCF.

On the established channel, the information flow of the terminal and the HRPD network is carried by a data burst message.

Step 32, the terminal establishes an HRPD session with the HRPD network AN.

On the basis of establishing the CDMA2000 1x air interface channel in step 31, and then using the channel between the CDMA2000 1x BSC and the HRPD AN, the terminal can establish an HRPD session with the HRPD network AN.

Step 33, the HRPD network AN allocates a wireless service channel for the terminal.

The specific implementation of this step is that the terminal sends a connection request message to the BSC through the CDMA2000 1x air interface data burst message, and the BSC forwards it to the HRPD network AN, and sends a path update message to the AN of the HRPD network. or,

The terminal sends a connection request message and a path update message to the BSC through the 1x air interface data burst message, and the BSC forwards it to the HRPD network AN;

The HRPD network AN allocates a wireless service channel to the terminal according to the connection request message and the path update message. The HRPD network AN sends the service channel allocation message to the terminal through the BSC.

Step 34, the AN establishes a connection with the packet control function module PCF of the HPRD network, and the PCF establishes a connection with the packet data service node PDSN of the HPRD network;

The AN and the PCF establish an A8 connection, or directly use the A9 signaling connection, or use both connections at the same time.

The PCF and the PDSN establish an A10 connection and use the A11 signaling connection at the same time.

Step 35, the terminal establishes a PPP connection with the PDSN.

First use the LCP protocol for parameter negotiation, then carry out the authentication process, and finally the PDSN uses the IPCP protocol to assign an IP address to the terminal, and the PPP connection is established.

In step 32, the terminal and the HRPD network AN can establish the HRPD session by means of two channels existing between the CDMA2000 1x BSC and the HRPD AN:

The first way is illustrated in conjunction with accompanying drawing 4, that is, to use the direct A21 interface, a new signaling message needs to be defined, and its detailed flow is:

Step 41, the terminal sends a data burst message to the BSC of the CDMA2000 1x network, the type of the data burst message is a burst message carrying an HRPD information flow, and the BSC replies to a layer 2 confirmation message;

Step 42, the BSC sends an HRPD air interface message to the AN of the HRPD network through the A21 interface, the message carries the information flow that the terminal interacts with the HRPD network, and the AN replies with a confirmation message;

Step 43, the AN sends an HRPD air interface message to the BSC through the A21 interface, the message carries the information flow between the terminal and the HRPD network, and the BSC replies with a confirmation message;

Step 44, the BSC sends a data burst message to the terminal, the message carries the information flow that the terminal interacts with the HRPD network, and the terminal replies with a layer 2 confirmation message;

Step 45, the BSC sends an event notification message to the AN.

In conjunction with the second method of accompanying drawing 5, that is, the CDMA2000 1x BSC is connected to the AN through the MSC, the relevant message fields need to be modified, and the detailed process is as follows:

Step 51, the terminal sends a data burst message to the CDMA2000 1x BSC, and the terminal replies with a layer 2 response message to the CDMA2000 1x BSC;

The format of the data burst message is shown in the following table:

field Length(bits) illustrate MSG_NUMBER 8 The serial number of the data burst message in the data burst information flow (HRPD network information flow) BURST_TYPE 6 Types of Burst Messages NUM_MSGS 8 Segmentation of this data burst information flow

The total number of data burst messages for NUM_FIELDS 8 The number of information bytes carried by the data burst message

NUM_FIELDS occurrences of

the following field:

{(NUM_FIELDS)

chari 8 Information carried by the data burst message }(NUM_FIELDS)

Currently, the data burst type BURST_TYPE has been used up to 000111, and 001000 to 111101 are reserved.

In order to realize the present invention, it is necessary to extend the data burst message, that is, to create a new BURST_TYPE as a data burst message carrying HRPD network-related information. For example, newly created BURST_TYPE is 001000.

Step 52, the CDMA2000 1x BSC sends the application data delivery service ADDS (Application Data Delivery Service) to the CDMA2000 1x terminal to send a message;

In the present invention, the ADDS User Part information element of the ADDS message is extended, and the data burst type Data Burst Type defines a suggested new value 001000 to indicate that the Application Data Message transmits HRPD network-related information. The details are as follows:

Step 53, CDMA2000 1x MSC sends ADDS paging message to HRPD AN;

In the present invention, the ADDS User Part information element of the ADDS paging message is extended, and the Data Burst Type defines a suggested new value of 001000 to indicate that the Application DataMessage transmits HRPD network-related information. The details are as follows:

Step 54, HRPD AN sends BS Service Request to CDMA2000 1x MSC;

In the present invention, the ADDS User Part information element of the BS Service Request message is extended, that is, a suggested new value 001000 is defined for the Data Burst Type to indicate that the ApplicationData Message transmits information related to the HRPD network; CDMA2000 1x MSC replies BS to HRPDAN Service Respond;

Step 55, CDMA2000 1x MSC sends ADDS message to CDMA2000 1x BSC;

Step 56, CDMA2000 1x BSC sends a data burst message to the terminal, and the terminal replies with a layer 2 Ack message to the BSC;

In step 57, the BSC replies with an ADDS sending confirmation message to the MSC.

Step 58: The CDMA2000 1x MSC sends an Event Notification message to the HRPD.

The present invention needs to expand the Event information element of the Event Notification message, and add 0000 0011 in the event identifier to indicate that HRPD network-related information is successfully sent to the terminal. The formats of Event and Event Identifier are as follows:
