Description

Method and device for user equipment registration/routing update

The present invention relates to the field of wireless communication technologies, and in particular, to a method and device for user equipment registration/routing update. Background technique

With the development of communication network technology, in the process of constructing a communication cell, in order to maximize the sharing of wireless resources and save the network construction cost of the operator, the network sharing is introduced. The network sharing structure includes MOCN (Multi-Operator Core Network) and GWCN (Gateway-Way Core Network).

The so-called MOCN means that the core networks of multiple operators are connected to the same access network node, and the access network nodes belong to different operators. In the MOCN cell, the system message of the cell broadcasts a public PLMN (Public Land Mobile Network) so that user equipments of different operators can camp on the cell.

When different user equipments of different operators initiate a registration/routing update request to the MOCN cell, the BSC (Base Station Controller) of the MOCN cell cannot identify the operator to which each user equipment belongs, and can only randomly Each user equipment selects an SGSN (Serving GPRS Support Node) A, and sends a registration/routing update request carrying the user equipment to the SGSN A to facilitate the registration/routing of the user equipment to the SGSNA.

When receiving the registration/routing update request of the user equipment a sent by the BSC, the SGSN A establishes a data transmission with the user equipment a, and performs authentication processing on the user equipment a to determine whether to accept the user equipment a. Registration/routing update request.

The data transmission between the SGSN A and the user equipment a is transmitted in the form of a UI (Unconfirmed Information Format) frame.

The UI frame includes a data transmission parameter, and the data transmission parameter indicates that the sender currently sends the data. The frame number of the UI frame, or the frame number of the UI frame that the receiving end currently expects to receive, that is, the condition for data transmission between the SGSN A and the user equipment a is the data transmission parameter of the user equipment a and the data transmission parameter of the SGSNA. Similarly, once the data transmission parameters of the user equipment a are different from the data transmission parameters of the SGSNA, the user equipment a cannot recognize the received UI frame and discards it as a data error.

It should be noted that the data transmission parameters of the user equipment a and the data transmission parameters of the SGSN A change with the number of data transmissions between the SGSN A and the user equipment a.

The SGSNA establishes a new data transmission channel with the user equipment b when receiving the registration/routing update request of the user equipment b sent by the BSC. At this time, the data parameter sent by the SGSN A to the user equipment b is not established. On the basis of the user equipment a, it is a data parameter in an initial state, wherein the data parameter in the initial state refers to a parameter state in which the SGSN side uses the UI frame for the first time to perform data transmission with the user equipment side.

When the SGSN A authenticates the user a and determines that the registration/routing update request of the user equipment a cannot be accepted, the SGSN A sends a rerouting indication message indicating that the user equipment a is rerouted to the BSC, so that the BSC is again User equipment a randomly selects other SGSNs.

The protocol stipulates that, in the above case, the SGSNA carries the data parameter value after the SGSNA and the user equipment a perform data transmission in the BSC rerouting indication message. Assuming that the BSC randomly selects the SGSN B for the user equipment a, the SGSN B sets the data parameter of the SGSN B to the data parameter value after receiving the data transmission by the SGSNA and the user equipment a after receiving the rerouting indication message. The data transmission with the user equipment a is started, and the data parameters of the other SGSNs selected by the BSC for the user equipment a are consistent with the data parameters of the user equipment a.

However, in practical applications, for various reasons, after the SGSN registration/routing update selected by the BSC for the user equipment a fails, when the SGSN B is selected again for the user equipment a, the SGSNA cannot be transmitted with the user equipment a. The data parameter value is sent to the SGSN B, causing the data transmission parameter of the user equipment a to be inconsistent with the data transmission parameter of the SGSN B, and further, because the user equipment a cannot identify the data sent by the SGSN B, the data transmission between the user equipment a and the SGSN B is performed. Failure, reducing the success rate of user device registration/routing updates. Summary of the invention

In order to achieve the object of the present invention, an embodiment of the present invention provides a method and a device for registering/routing a user equipment, by receiving a rerouting message carrying a registration/routing update request of a user equipment sent by a BSC, according to the Transmitting the routing information, and sending the parameter status reset information to the user equipment, where the parameter status reset information is used to trigger the user equipment to reset the data transmission parameter of the user equipment to an initial state, so that the user after the reset The data transmission parameter of the device is consistent with the data transmission parameter of the target GPRS service support node SGSN, such that the SGSN is the service node of the first registration/routing update request randomly selected by the BSC for the user equipment, and each SGSN receives the BSC. When the re-routing information of the registration/routing update request of the user equipment is sent, the data transmission parameter of the user equipment is triggered to be reset to an initial state, that is, the data transmission parameter of the user equipment is adjusted to perform data interaction with the SGSN for the first time. State, ensuring data transmission of user equipment The transmission parameters are consistent with the data transmission parameters of the SGSN, which effectively avoids that the data transmission parameters of the user equipment are inconsistent with the data transmission parameters of the SGSN, and the user equipment cannot identify the data transmitted by the SGSN, and the data transmission between the user equipment and the SGSN fails. The problem is that the success rate of user device registration/route update is improved.

It should be noted that the embodiment of the present invention may be, but is not limited to, being applied in a scenario where the BSC fails to register/route the user equipment, for example, after the BSC receives the registration/routing update request of the user equipment, A registration/routing update request is sent to the first randomly selected SGSN for the user equipment, and the first randomly selected SGSN may also use embodiments of the present invention.

It should be noted that the data transmission parameter of the user equipment may be in an initial state, which is consistent with the second data transmission parameter of the first randomly selected SGSN, but there may be cases where the data transmission parameters may be inconsistent. The problem that the user equipment registration/routing update fails due to the data transmission parameters of the user equipment and the data transmission parameters of the SGSN is more effectively avoided.

The data transmission parameter of the user equipment may be a V (UR) parameter, indicating that the sequence number of the UI frame that is currently sent by the network side is expected to be received, and may also be other parameters (for example, the count value after receiving the network side data) The data transmission parameter of the SGSN may be an N ( U ) parameter, that is, a Transmitter unconfirmed sequence number, indicating that the network currently sends the UI † j3⁄4 sequence 歹 'J number, and may also be other parameters (for example: sending network side data) Count value).

If the data transmission parameter of the user equipment and the data transmission parameter of the SGSN side are both represented by the count value, the data transmission parameter of the user equipment needs to be the same as the initial value of the data transmission parameter of the SGSN and the counting step size needs to be the same.

The manner in which the data transmission parameters of the user equipment are consistent with the data transmission parameters of the SGSN includes but is not limited to:

Assuming that the data transmission parameter of the current SGSN is X, then the data transmission parameter of the user equipment is

X.

When the SGSN sends a UI frame to the user equipment, the currently transmitted UI frame carries the data transmission parameter X of the SGSN; when the current UI frame is sent, the data transmission parameter of the SGSN becomes X+1; when the SGSN again goes to the user equipment When the UI frame is sent, the currently transmitted UI frame carries the data transmission parameter X+1 of the SGSN.

When receiving the UI frame, the SGSN reads the data transmission parameter X of the currently transmitted UI frame and compares it with the data transmission parameter X of the user equipment, and compares the data of the SGSN carried in the currently transmitted UI frame. When the transmission parameter is the same as the data transmission parameter of the user equipment, confirm that the reception is correct, and change the data transmission parameter of the user equipment to X+1; when the currently sent UI When the data transmission parameter of the SGSN carried in the frame is different from the data transmission parameter of the user equipment, the UI frame received this time is discarded.

The various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Embodiment 1:

As shown in FIG. 1 , it is a schematic flowchart of a method for user equipment registration/routing update according to Embodiment 1 of the present invention. The method can be as follows.

Step 101: The network side device receives the rerouting information sent by the base station controller BSC.

The rerouting information carries a registration/routing update request of the user equipment.

In step 101, the scenario of receiving the rerouting information sent by the base station controller BSC includes but is not limited to:

The first case:

Step 1: Establish an air interface between the user equipment and the BSC.

Step 2: The BSC receives data sent by the user equipment including the registration/routing update request and the device identifier of the user equipment.

It should be noted that the device identifier of the user equipment belongs to a temporary identifier, or a random identifier, a foreign TLLI (temporary Logical Link Identifier), a random TLLI, and the like.

Step 3: After receiving the data of the device/device update request and the device identifier of the user equipment sent by the user equipment, the BSC cannot determine which carrier the user equipment belongs to according to the device identifier of the user equipment (or belong to the operator). Which PLMN) triggers the rerouting process.

Step 4: The BSC randomly selects an SGSN (referred to as the first SGSN at this time), and sends an uplink data PDU (Protocol Data Unit) to the first SGSN, and carries the user equipment in the uplink data PDU. Registration/Routing Update Request and Redirect attempt flag information.

The rerouting indication is used by the SGSN to instruct the BSC to reselect another SGSN for the user equipment after the SGSN fails to respond to the registration/routing request of the user equipment.

Step 5: After receiving the uplink data PDU sent by the BSC, the first SGSN uses the uplink data PDU The user device sends an identity authentication request.

The identity authentication request indicates that the user equipment reports the identity information of the user equipment that can identify the user equipment (for example, an IMSI (International Mobile Subscriber Identifier).

Step 6: The first SGSN determines, according to the identifier information reported by the user equipment, that the registration/routing update request of the user equipment cannot be accepted, and sends a downlink data PDU indicating that the user equipment re-routing is performed to the BSC.

At this time, the BSC will randomly select an SGSN (reported as the second SGSN at this time) and send re-routing information to the second SGSN.

That is to say, the second SGSN starts the operation of step 101 at this time, and receives the rerouting information sent by the BSC.

The second case:

Step 1: Establish an air interface between the user equipment and the BSC.

Step 5: After the BSC sends the uplink data PDU to the first SGSN, the first SGSN does not respond to the uplink data PDU sent by the BSC, so that the BSC is in a waiting state until the air interface is connected. The connection is released, causing the user device registration/routing update to fail.

It should be noted that there are many reasons why the first SGSN does not respond to the uplink data PDU sent by the BSC. The reason is that the first SGSN does not respond in time due to the large amount of service processing, and may also be network congestion, which is not limited herein.

The third scenario:

Step 1: Establish an air interface between the user equipment and the BSC.

Step 5: After the BSC sends the uplink data PDU to the first SGSN, the BSC starts a timer. When the first SGSN does not respond to the uplink data PDU sent by the BSC, the BSC determines that the current user equipment is determined when the timer expires. The rerouting operation of the registration/routing update failed.

At this time, the BSC will randomly select one SGSN (reported as the second SGSN at this time) and send re-routing information to the second SGSN. That is to say, the second SGSN starts to perform the operation of step 101 at this time, and receives the rerouting information sent by the BSC.

The fourth situation:

Step 1: Establish an air interface between the user equipment and the BSC.

Step 5: After receiving the uplink data PDU sent by the BSC, the first SGSN sends a downlink data PDU indicating that the user equipment is re-routed to the BSC due to busy network or other faults.

Step 102: The network side device sends parameter state reset information to the user equipment according to the rerouting information.

The parameter state reset information is used to trigger the user equipment to reset the data transmission parameter of the user equipment to an initial state, so that the data transmission parameter and the target of the user equipment after the resetting The data transmission parameters of the GPRS service support node SGSN are consistent.

In step 102, the manner in which the network side device sends the parameter state reset information to the user equipment according to the rerouting information includes, but is not limited to:

The first way:

And determining, by the network side device, the parameter state reset information to the user equipment when the data transmission parameter of the source SGSN is not carried in the rerouting information according to the rerouting information.

That is, it is determined whether the parameter state reset information is sent to the user equipment by determining whether the data transmission parameter of the source SGSN is carried in the rerouting information.

First, according to the rerouting information, it is determined whether the data transmission parameter of the source SGSN is carried in the rerouting information.

In step 101, the BSC randomly selects the first SGSN to cause the user equipment registration/routing update to fail, and the second SGSN is selected again for the user equipment registration/routing update as an example.

When the first SGSN does not respond in time, so that the BSC determines that the operation of the user equipment registration/routing update to the first SGSN fails, or the first SGSN sends a downlink data PDU to the BSC indicating that the rerouting indication is re-routed for the user equipment. When the second data transmission parameter value of the first SGSN is not carried in the BSC, the BSC cannot determine the first data transmission parameter value of the current user equipment. Therefore, when receiving the rerouting information sent by the BSC, the second SGSN needs to determine the rerouting. Whether the data transmission parameter of the first SGSN is carried in the information.

Secondly, based on the determination result, determining whether to send the parameter status reset information to the user equipment. When the result of the judgment is that the data transmission parameter of the source SGSN is not carried in the rerouting information, the parameter state reset information is sent to the user equipment.

When the result of the judgment is that the data transmission parameter value of the first SGSN is carried in the rerouting information, according to the data transmission parameter value of the first SGSN, the BSC is the data of the second SGSN selected by the user equipment registration/routing update. The transmission parameter information is adjusted to receive the data transmission parameter value of the first SGSN carried in the rerouting information, and perform subsequent operations. Or determining, when the data transmission parameter information of the source SGSN is carried in the rerouting information, determining, according to the data transmission parameter information of the source SGSN, that the state of the data transmission parameter of the current user equipment is not in an initial state, further determining The data transmission parameter of the user equipment is inconsistent with the data transmission parameter carried in the UI frame to be delivered by the target SGSN selected by the BSC for the user equipment registration/routing update, and the parameter status reset information is sent to the user equipment.

The second way:

If the re-routing information carries the first indication information, and the first indication information is used to indicate that the data transmission parameter of the user equipment is not in the initial state, the network side device sends the information to the user equipment. Parameter status reset information.

Specifically, according to the first indication information carried in the rerouting information, and the first indication information is used to indicate that the data transmission parameter of the user equipment is not in the initial state, determining a data transmission parameter of the user equipment and the current The data transmission parameters carried in the UI frame to be delivered by the SGSN are inconsistent, and the parameter status reset information is sent to the user equipment.

The third way:

If the re-routing information carries the second indication information, and the second indication information is used to indicate that the network side device triggers the user equipment to reset the data transmission parameter of the user equipment, the network side device Sending the parameter status reset information to the user equipment.

It should be noted that the initial state of the data transmission parameter may be a zero state or other set state, which is not specifically limited herein.

This ensures that the data transmission parameters of the user equipment are consistent with the data transmission parameters of the SGSN, and the problem that the user equipment registration/routing update fails due to the data transmission parameters of the user equipment and the data transmission parameters of the SGSN is avoided.

It should be noted that the parameter status reset information sent by the network side to the user equipment may be carried by the XID Command message, which is not limited herein.

In another embodiment of the present invention, the network side device triggers the target SGSN to respond to the registration/routing update request of the user equipment when determining that the data transmission parameter of the user equipment is consistent with the data transmission parameter of the target SGSN. The manner in which the target SGSN responds to the registration/routing update request of the user equipment includes, but is not limited to: authenticating the device identifier reported by the user equipment, and determining whether to accept the registration/routing update request of the user equipment according to the result of the authentication processing.

Upon determining to accept the registration/routing update request of the user equipment, returning to the BSC to accept registration/routing update request information of the user equipment;

When it is determined that the registration/routing update request of the user equipment is not accepted, the rerouting indication information is returned to the BSC, where the rerouting indication information is used to instruct the BSC to perform a rerouting operation on the user equipment.

Therefore, the data transmission parameter of the user equipment is set to the initial state (or the zero state) in the manner of step 102, so that the data transmission parameter of the user equipment is consistent with the data transmission parameter of the SGSN, and the SGSN and the user equipment are ensured. The communication is smooth, and the success rate of user equipment registration/routing is improved.

It should be noted that the executor network side device of the first embodiment of the present invention may be a control device other than the source SGSN and the target SGSN, and may also be a target SGSN, which is not limited herein.

According to the solution of the first embodiment of the present invention, when receiving the re-routing information of the registration/routing update request of the user equipment that is sent by the BSC, sending the parameter status reset information to the user equipment according to the re-routing information, The parameter state reset information is used to trigger the user equipment to reset the data transmission parameter of the user equipment to an initial state, so that the data transmission parameter of the user equipment after the reset is consistent with the data transmission parameter of the target GPRS service support node SGSN. In this way, regardless of whether the SGSN is a serving node of the first registration/routing update request randomly selected by the BSC for the user equipment, each SGSN, when the received BSC sends the re-routing information including the registration/routing update request of the user equipment, The triggering resets the data transmission parameter of the user equipment to an initial state, that is, adjusting the data transmission parameter of the user equipment to the state of data interaction with the SGSN for the first time, ensuring that the data transmission parameter of the user equipment is consistent with the data transmission parameter of the SGSN. , effectively avoiding the data transmission parameters of the user equipment and SGS The data transmission parameters of N are inconsistent. The user equipment that is triggered cannot identify the data sent by the SGSN, causing the data transmission between the user equipment and the SGSN to fail. The problem is to increase the success rate of user device registration/route updates.
