Description

A radio access network triggered paging processing method and device

technical field

The present invention relates to the technical field of network communication, in particular to a radio access network triggered paging processing method and device.

Background technique

With the rapid development of Internet services and the wide application of wireless networks, the number of mobile users has increased rapidly, and the demands of users have also increased rapidly. This undoubtedly requires wireless technologies such as GPRS (General Packet Radio Service), Wireless technologies such as 3G, WiMAX and B3G (Beyond 3G; post-3G) can support multiple services with large capacity, large data volume and different service quality requirements.

As a bridge between wireless users and existing wired networks or other service networks, wireless access technology mainly completes the function of forwarding or routing packet services between the network and mobile users.

The following takes the WiMAX network architecture system shown in Figure 1 as an example to illustrate the functions of each network element in the WiMAX wireless access system using wireless access technology:

In Fig. 1, the WiMAX wireless access system includes MSS (Mobile Subscribe Station), ASN (Access Service Network; access service network) and CSN (Connectivity Service Network; connection service network).

Wherein, the MSS is a mobile user terminal equipment, and the user uses this equipment to access the WiMAX network.

Wherein, the ASN includes BS (Base Station; base station) and ASN-GW (Access Service Network GateWay; access service network gateway), etc., which are used to provide a set of network functions for WiMAX terminal equipment to provide wireless access services. For example, based on the BS, it provides functions such as connection between BS and MSS, radio resource management, measurement and power control, air interface data compression and encryption; based on the ASN-GW, it provides proxy functions for MSS authentication, authorization and charging functions , Support NSP network discovery and selection, provide MSS with L3 information relay function (such as IP address allocation), wireless resource management and other functions.

Wherein, the CSN is used to provide IP connection services for WiMAX terminals. For example, allocating IP addresses for MSS, providing Internet access, providing AAA proxy or server, providing user-based authorization control, and providing tunnels from ASN to CSN, which is equivalent to HA (home agent) in mobile IP technology and providing WiMAX user Billing and settlement between operators, tunnel between CSNs in roaming, handover between different ASNs, and various WiMAX services (such as location-based services, multimedia multicast and broadcast services, IP multimedia subsystem services )wait.

The following still describes the process of data transmission between network elements in conjunction with Figure 1:

The packet service data message of the downlink MSS is transmitted from the HA of the CSN to the ASN through the R3 interface between the HA in the CSN and the ASN-GW in the ASN (called the anchor ASN-GW), and is sent by the ASN-GW The MSS data is sent to the MSS through the R6 interface between the ASN-GW inside the ASN and the BS, and the R1 interface between the BS and the MSS.

If the ASN-GW connected to the HA in the CSN is different from the ASN-GW of the BS that controls MSS access (called the serving ASN-GW), the packet service datagram of the downlink MSS is sent from the HA of the CSN to the ASN through the HA. The R3 interface between the anchor ASN-GW is transmitted to the ASN, and the anchor ASN-GW passes through the R4 interface between the anchor ASN-GW and the serving ASN-GW inside the ASN, and the R6 interface between the ASN-GW and the BS The R1 interface between the BS and the MSS sends data from the MSS to the MSS. Uplink data is passed from MSS to CSN along the opposite path and reaches the opposite end user.

As mentioned above, in the interface inside the ASN, there are corresponding uplink and downlink data channels for each service flow of each MSS, which will be based on the QoS requirements and data channels of each service flow when each service flow is established. established by the adoption method. When the service ends, that is, when the service flow is terminated, the corresponding data channel needs to be released.

However, these can be completed when the MSS initiates a service request, and when the peer user initiates a service connection with the MSS, the packet datagram sent by the peer user will reach the anchor of the MSS through the R3 interface The ASN-GW is the endpoint of the R3 interface of the MSS in the ASN. That is, the paging process is triggered. Because the establishment of the service is initiated by the opposite end user, no data channel for the service is established in the ASN and between the BS and the MSS.

In order to solve the above problems, the technical solution of prior art 1 is: when a peer user needs to be paged, since the MSS to be paged has established a signaling connection with the core network, the paging request of the peer user will It is sent to the MSS through a special paging channel, triggering the MSS to initiate the establishment process of the data link.

The disadvantage of the prior art 1 is that this technology is based on the existing signaling connection, sends the paging request to the MSS through a dedicated signaling channel, and triggers the MSS to establish a data link. The signaling channel needs to be specially maintained, and there must be a signaling analysis function in the terminal or network, but in some systems such as WiMAX systems, there is no dedicated signaling channel to handle paging, so a new method/technology needs to be sought to solve this problem.

Therefore, prior art 2 proposes that under the premise that the service flow channel between the paging terminal and the paged terminal has been established, the MSS enters an idle state, and there is no service data channel in the anchor ASN-GW and MSS, but there are multiple services The data flow information exists in the paging controller, and the packet datagram that triggers paging actually belongs to a certain service flow in these data flows, then the paging controller paging MSS leaves the idle state and enters the active state, and the MSS After entering the active state, corresponding multiple data service channels are quickly rebuilt for these data streams, so that the packet datagram can be sent to the MSS on the corresponding data channel, and the paging process is completed.

The shortcoming of the prior art 2 is that the realization of this technology needs to have the service flow information corresponding to the MSS packet datagram in the paging controller, so that the packet datagram can be sent to the MSS, if the paging controller If there is no corresponding service flow information in the network, the data cannot be transmitted, resulting in data loss, and finally the end-to-end data communication cannot be realized when the opposite end user is calling.

Detailed ways

The core idea of the present invention is to provide a new downlink data channel for the downlink packet datagram to transfer it from the anchor ASN-GW when the MSS is paged and the packet datagram sent by the opposite end user reaches the anchor ASN-GW. The method and device for transmitting to the MSS solve the problem of how to send the datagram to the MSS when there is no corresponding data channel when the downlink packet datagram arrives.

The present invention provides a wireless access network trigger paging processing device, as shown in Figure 2, the device includes: a downlink data channel establishment module 1, a downlink data channel modification module 2, an uplink data channel establishment module 3; the downlink data channel Establishment module 1 is used to establish a downlink data channel for downlink packet datagrams. During the establishment process, if the quality of service parameters of the downlink data channel and other characteristics of the data channel cannot be determined, the data can be created according to the default basic parameters of the data channel. The channel is established according to some parameters corresponding to the basic service type of the datagram. The parameters include: bandwidth, data throughput, data delay, delay jitter, etc., which can be pre-configured by the system, or by the peer user according to It needs to be carried in the datagram; if the wireless access network can determine the general characteristics of the downlink service datagram, it can use the estimated parameters to create a new data channel;

The downlink data channel modification module 2 is used for the MSS to modify the downlink service data channel established by the downlink data channel establishment module 1 according to the quality of service requirements of the received downlink packet data;

The uplink data channel establishment module 3 is used to establish an uplink data channel according to application requirements, and the signal flow of the establishment process is the same as that of the downlink data channel modification process.

The present invention provides a wireless access network trigger paging processing method, as shown in Figure 3, the operation flow chart of the method according to the present invention, assuming that the paging controller, anchor ASN-GW, and serving ASN-GW are all different For the ASN-GW entity, the method of the present invention will be described in detail below with reference to Fig. 2 and Fig. 3, and the method specifically includes:

Step 10: start to trigger paging, the HA in the CSN transmits the downlink packet datagram of the MSS to the anchor ASN-GW;

Step 11: The anchor ASN-GW receives the downlink packet datagram of the MSS, buffers it, and judges whether the MSS is in an idle state;

Since the MSS disconnects the R1, R4, and R6 interfaces when it is in the idle state, and notifies the anchor ASN-GW of the idle state message, the anchor ASN-GW can judge whether the MSS is in the idle state according to the message;

Step 12: If the MSS is in an idle state, then page the MSS;

The process specifically includes: the anchor ASN-GW sends an MSS paging message to the paging controller, and the paging controller sends a response to the anchor ASN-GW after receiving the message, indicating whether the message is received, and then the paging control The device then sends the MSS paging message to all serving ASN-GWs and BSs in the paging group registered by the MSS in turn, and the BS sends the paging message to the MSS in the form of a broadcast message;

Step 13: After receiving a paging message from a BS, the MSS exits the idle state within the coverage of the BS, and notifies the BS that the MSS has exited the idle state, then the BS obtains the information of the existing service flow of the MSS, Rebuild data channels for these existing business flows;

This process specifically includes: after the MSS exits the idle state, it notifies the paging controller of the corresponding exit idle state message, and the paging controller sends the message to the BS, the serving ASN-GW and the anchor ASN-GW, and the BS obtains After the MSS exits the idle state information, it obtains all the service flow information of the MSS from the paging controller. After obtaining the information, the BS initiates the establishment of the service data channel within the ASN of the MSS. First, the BS and the serving ASN-GW are established. After that, the channel between the serving ASN-GW and the anchor ASN-GW is established, and at the same time, the connection between the MSS and the BS that supports these service flows is quickly established according to the method stipulated in the 802.16e protocol. After the above-mentioned channel is established , notify the anchor ASN-GW of the channel establishment message;

If it is judged in the above step 11 that the MSS is in an active state, then directly execute step 14;

Step 14: The downlink data channel establishment module 1 creates a new downlink data channel for the downlink packet datagram, and controls the establishment process of the entire data channel;

The specific operations include: the anchor ASN-GW actively initiates a data channel establishment request to the serving ASN-GW, and the message carries quality of service parameters, channel characteristic parameters such as channel number, etc. If the parameters and other characteristics of the data channel cannot be determined, you can Create a new data channel with some parameters of the corresponding basic service type; if you can determine the general characteristics of the downlink service datagram, you can use the estimated parameters to create a new data channel; the serving ASN-GW sends it to the BS, and the BS sends a dynamic service increase to the MSS The request message is shown as the DSA-REQ in Figure 3. After receiving the request message, the MSS sends a response message to the BS, and the BS sends the data channel establishment response message to the serving ASN-GW, the anchor ASN-GW, and the anchor ASN-GW in turn. After receiving the response message, send confirmation messages to the serving ASN-GW, BS and MSS in sequence, indicating that the new data channel is established successfully;

Step 15: Once the downlink service data channel is successfully established, the anchor ASN-GW sends the cached downlink packet datagram of the MSS to the MSS along the newly created downlink data channel;

Step 16: The downlink data path modification module 2 modifies the parameters of the downlink data path according to the received downlink packet datagram, and applies for modifying the downlink data path inside the ASN and between the BS and the MSS through a dynamic service modification request message;

The specific modification operation includes: the MSS sends a dynamic service modification request message to the BS, as shown in DSC-REQ in Figure 3, and the BS sends a response message to the MSS after receiving the request message, indicating whether the request is received, and at the same time sends the request message as The data channel modification request message is sent to the serving ASN-GW, which carries the quality of service parameters of the downlink packet datagram, channel characteristic parameters such as channel number, etc., and is sent to the anchor ASN-GW by the serving ASN-GW. The GW and the anchor ASN-GW sequentially send data channel establishment response messages to the serving ASN-GW, BS, and MSS. After receiving the response messages, the MSS sends confirmation messages to the BS, serving ASN-GW, and anchor ASN-GW in sequence. After the service data channel modification process is completed, all downlink packet datagrams of this type will be sent to the MSS through this channel;

Step 17: According to the requirements of the application, the uplink data channel establishment module 3 can apply for a new uplink data channel within the ASN of the service and between the BS and the MSS through the dynamic service increase request message DSA-REQ, and the MSS passes through the uplink data channel , can send data to the calling party. The establishment process of the uplink data channel is similar to the modification process of the downlink service data channel, and will not be described here.

In summary, the present invention realizes the establishment of a new downlink data channel for the downlink packet datagram, and solves the problem of how to send the datagram to the MSS when there is no corresponding data channel when the downlink packet datagram arrives. MSS can be effectively paged in both idle and active states, and the session corresponding to the downlink data service can be clearly distinguished from the data channels corresponding to other existing sessions, and will not be confused with other existing service data sessions.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changes or Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
