Problems solved by technology

[0009] The purpose of the present invention is to provide a method for processing messages on wireless access networks under the A-Flex framework, so as to solve the problem of sending response messages to the original MSC when the load balance changes, sending request messages to the new MSC, and the new MSC Cooperate with the original MSC to complete business processing issues

Embodiment 1

[0051] Embodiment 1: When the load balance changes, the BSC obtains the MSC ID registered by the user through the Tag parameter in the request message and then sends a response message. figure 2 Shown:

[0052] 1. MSC1 (Mobile Switching Center 1) sends a control channel short message message to BSC (Base Station Controller), including IMSI (International Mobile Subscriber Identity) and Tag (label) parameters, and the Tag parameter contains MSC (Mobile Switching Center) ) logo;

[0053] 2. The BSC base station controller buffers the Tag label identification, and sends a DATABurst (data burst) message to the MS mobile user through the air interface;

[0054] 3. At this time, the load needs to be redistributed, and some users of MSC1 need to be migrated to MSC2;

[0055] 4. The MS (mobile subscriber) returns a link layer response message to the BSC base station controller;

[0056] 5. The BSC base station controller takes out the cached Tag parameter, and sends the control ch...

Embodiment 2

[0057] Embodiment 2: When the load balance changes, the BSC obtains the MSC ID registered by the user by sending the request message MSC address information, and then sends a response message. image 3 Shown:

[0058] 1. MSC1 (Mobile Switching Center 1) sends a control channel short message delivery message to BSC (Base Station Controller), including IMSI (International Mobile Subscriber Identity) parameters;

[0059] 2, BSC base station controller saves the address information of this MSC1 (mobile switching center 1) (this information can be IP address plus port number or source signaling point plus subsystem number, obtain from the network layer address of sending message), and Send a DATABurst (data burst) message to the MS (mobile user) through the air interface;

[0060] 3. At this time, the load balance changes, and some users of MSC1 migrate to MSC2;

[0061] 4. The MS (mobile subscriber) returns a link layer response message through the air interface;

[0062] 5. Th...

Embodiment 3

[0063] Embodiment 3: When the MSC failure situation responds to the message and sends the flow process of processing as attached Figure 4 Shown:

[0064] 1. MSC1 (Mobile Switching Center 1) sends a control channel short message message to BSC (Base Station Controller), including IMSI (International Mobile Subscriber Identity) and Tag (label) parameters, and the Tag parameter contains MSC (Mobile Switching Center) ) logo;

[0065] 2. The BSC caches the Tag identification, and sends a DATABurst (data burst) message to the MS mobile user through the air interface;

[0066] 3. At this time, MSC1 fails;

[0067] 4. The MS (mobile subscriber) returns a layer 2 response message through the air interface;

[0068] 5. The BSC takes out the cached Tag parameter, and judges that the information channel connected to the MSC has been disconnected according to the MSC identifier contained therein, then considers that MSC1 is faulty, and sends a Registration Request Order (registration r...

Abstract

The invention relates to a method for sending message on the wireless access network under A-Flex mode. Wherein, said method comprises: a, when the base station controller BSC sends message to the mobile exchange center MSC, judge if there is the MSC mark relative to said message, if there is, entering into step b, or else, entering into step C; b, the BSC sends said message to the MSC relative to the MSC mark, or instruct MS to register position again; c, BSC sends the message to new MSC which will broadcast the message to all internal MSC and process it according to feedback response.

Description

technical field [0001] The present invention relates to the technical field of A-Flex, and specifically relates to the processing of sending messages on a wireless access network under the A-Flex framework. Background technique [0002] With the development of communication systems and the substantial increase in network capacity, security is the focus of communication operators' increasing attention. In communication systems, large-scale service interruptions caused by single-point failures have a particularly large impact on system security. Therefore, avoiding large-scale service interruption caused by a single point of failure has become a technical problem that needs to be solved. [0003] lu-Flex (Iu interface Flexibility lu interface flexibility lu interface is the interface between the wireless access network and the core network in the GSM and WCDMA network) refers to the technology for connecting and communicating between one RNC / BSC and multiple CN network element...
