Definitions
- the present invention relates to a method for information exchange between a terminal and an HRPD network, and more particularly to a method for establishing a HRPD network packet data service in a lx network.
- the CDMA2000 l network is currently the largest CDMA network in terms of users, with circuit voice services and low- and medium-speed data services.
- CDMA2000 lx EV-DO is designed to optimize data applications, also known as High Rate Packet Data (HRPD).
- HRPD Version A has a reverse link of 1.8 Mbit/s and a forward link of 3.1 Mbit. The peak rate of /s.
- HRPD The key to superior performance is that it uses closed-loop rate control and Capacity enhancing scheduler to transmit data in bursts at the highest possible rate. For each user. In other words, the choice of modulation method and transmission time can be dynamically controlled according to the channel environment to obtain the best effect.
- HRPD Version A also has other enhancements, including Service Quantity (QoS), Instant Multi-Media, Location Services (LBS), Equalizer, Receive Diversity, VoIP, and Multi-Carrier.
- QoS Service Quantity
- LBS Location Services
- Equalizer Equalizer
- Receive Diversity VoIP
- Multi-Carrier Multi-Carrier
- the HRPD can independently build a wireless mobile data network, or it can complement the lx hybrid network to complement the functional requirements set by the ITU for the 3G system. Due to the fact that the 3G service market has not yet been fully launched and the construction cost of the network is considered, the hotspot coverage scheme is generally adopted in the first phase of HRPD network construction. Thus, at the edge of the HRPD network, there must be a problem of service switching between the lx and HRPD networks; at the same time, within the HRPD network, The same problem arises with the need for load regulation between lx and HRPD networks. Therefore, it is necessary to study the seamless handover between the lx and HRPD networks. The seamless handover, that is, the service interruption time caused by the handover is extremely low, so as to achieve complementary advantages between the two networks and ensure the user experience.
- the terminal does not occupy the wireless service channel in the HRPD network, but the terminal and the PDSN maintain the PPP logical connection, and the PDSN and the PCF maintain the A10 connection. This is called the terminal and the HRPD network have a sleep session.
- the network has data to send to the terminal, if the terminal is listening to the HRPD network, after receiving the paging message sent by the AN, the terminal initiates a connection establishment request to activate the data session, and the network allocates a wireless service channel and establishes a wired connection.
- the wired connection is an A8 connection; if the terminal performs service under the lx network, the HRPD network will request the lx network to send paging information to the terminal, and the terminal decides whether to transfer to the HRPD network to receive data.
- the data session is actively initiated. After the data transmission is completed, if there is no data interaction between the terminal and the HRPD network within a certain period of time, the data session sleep state may be entered again.
- the dormant handover means that when the terminal and the HRPD network have packet data service dormancy, due to the mobility of the terminal, the HRPD session information needs to be transferred from the source AN/PCF to the target AN/PCF to prepare for the packet data service activation.
- the session information is an HRPD air interface protocol attribute value and a related public data value
- the packet data service activation state refers to a service data transmission state. This process may lead to A10: Connection Switching, which refers to the connection between HRPD and AN/PCF, ie the new connection is established and the old connection is released.
- the HRPD network and the lx network have two different connectivity modes.
- the two methods may exist at the same time.
- the PDSN is a packet data service node
- the PCF is a packet control function.
- the AN is the access network; on the lx network side, the MSC is the mobile switching center, and the BSS is the base station controller.
- the first way is that the HRPD network and the lx network are connected through the signaling interface Al/Alp, wherein the A1 interface is based on a circuit connection, the Alp is based on an IP connection, and the signaling interface Al/Alp is mainly used to transmit lx circuit service related signaling; Species The HRPD network and the lx network are connected through the signaling interface A21.
- the A21 interface is mainly used to transmit the lx air interface related message when the terminal performs the HRPD network service.
- lx network wireless interface is in the HRPD network. Establishing a packet data service will be beneficial to seamlessly switch between lx and HRPD networks.
- a channel is established on the air interface of the lx network, and is used for carrying information flow between the terminal and the HRPD network;
- the terminal establishes an HRPD session with the access network (AN), including assigning a unicast access terminal identifier (pATI), performing session negotiation, and possibly performing access authentication, and the like;
- AN access network
- pATI unicast access terminal identifier
- the AN establishes a connection with the packet control function (PCF), and the PCF establishes a connection with the packet data service node (PDSN);
- PCF packet control function
- PDSN packet data service node
- the terminal establishes a Point-to-Point Protocol (PPP) connection with the PDSN, possibly performing Mobile IP (MIP) registration.
- PPP Point-to-Point Protocol
- MIP Mobile IP
- the above method provides a method for establishing a packet data service with the HRPD network under the lx network when the terminal and the HRPD network have no packet data session, and does not solve the problem that the terminal establishes a new HRPD network packet data when the HRPD network has a dormant packet data session.

In addition, in this process, if the source AN/PCF and the target AN/PCF are not the same AN/PCF, the HRPD network sleep switching is required.
- the present invention establishes a new packet data service with the HRPD network when the terminal has a packet data session with the HRPD network and the session is in a data session dormant state.
- a dormant handover is required; if they are the same, the process of the service establishment is directly performed, but the process does not have a packet data session in the prior art. In this case, the process of establishing a new service is different.
- the present invention only needs to modify the configuration of an existing HRPD session, and add a corresponding new service to it, without establishing a new HRPD session for the service, and A PPP connection is established for the packet data session.
- AN and PCF are two network devices.
- the important session management/mobility management functions of the HRPD network can be implemented in AN or PCF.
- actual product implementations often involve AN and PCF, and private interfaces may be used between them.
- this article uses AN/PCF to describe the two devices as a whole, but does not mean that AN and PCF are one-to-one correspondence.

- the message includes an attribute record b, b is an attribute supported by both the terminal and the target AN PCF, and is a subset of a, thereby implementing configuration i of the IP flow, and updating the QoS of the IP flow;
- Step 108 Establish a connection between the target AN/PCF and the PDSN for the packet data service.
- the process is: the target AN/PCF sends an Al1 registration request message to the PDSN, where the target AN PCF and the PDSN are used to transmit service data.
- step 108 the terminal does not need to establish a PPP connection with the PDSN.
- the AN/PCF is connected to the MSC through the Al/Alp interface, and the other way.
