Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

In the technical scheme of the embodiment of the invention, an abnormal access scene is simulated, namely: the terminal (UE) side is not compatible with the existing base station version due to the extra NRI carried in the attach request message, which results in RRC disconnection, and the UE cannot access LTE.

And aiming at the abnormal access scene, executing the process of accessing the LTE network by adopting a preset optimization scheme at the terminal side, detecting whether the terminal is successfully accessed into the LTE network, and finally determining the effectiveness and the rationality of the optimization scheme adopted by the terminal so as to provide the accuracy of network optimization.

In the embodiment of the present invention, a network environment (referred to as a simulation network environment) may be constructed by a simulation platform, where the simulation network environment at least includes the following network structures: the System comprises an LTE network, a TDSCDMA network and a GSM network, wherein TDSCDMA neighboring cell Information is configured in (SIB, System Information Block)5 of the LTE network, GSM neighboring cell Information is configured in SIB7 of the LTE network, and LTE neighboring cell Information is configured in (SI, System Information) of the GSM network. In the embodiment of the invention, as an example, fig. 1 is a schematic diagram showing the configuration code of SIB5 through a computer display screen, fig. 2 is a schematic diagram showing the configuration code of SIB7 through the computer display screen, and fig. 3 is a schematic diagram showing the configuration code of SI through the computer display screen.

And then, executing an LTE network access process based on the constructed network environment, wherein main objects involved in the LTE network access process comprise a terminal and a network side, wherein the terminal can be realized by adopting a mobile phone but not limited to be realized by adopting the mobile phone, and the network side can be realized by adopting a simulation platform. Here, because the network side is realized by adopting the simulation platform, the network can stably reproduce an abnormal access scene between the network and the terminal, thereby verifying the effectiveness and the rationality of the optimization scheme.

Based on the above simulated network environment, the following describes the technical solution of the embodiment of the present invention in detail.

Fig. 4 is a flowchart illustrating a method for detecting an LTE network access result according to an embodiment of the present invention, where the technical solution of this embodiment is applied to a process in which a terminal performs LTE network access by using a preset optimization scheme, and as shown in fig. 4, the method for detecting an LTE network access result includes the following steps:

s101, receiving a first attachment request message sent by a terminal when the terminal is in RRC connection with the terminal.

In the embodiment of the invention, a method for detecting an LTE network access result in the process of realizing Short Message Service (SMS) is provided.

It should be noted that the UE of LTE is attached to Evolved Packet System services (EPS services, Evolved Packet System services) and non-EPS services (non-EPS services) by performing a joint ATTACH procedure in the LTE System. After successful attachment, an SGs interface is established between a Mobility Management Entity (MME) of the EPS services and a Mobility Management Entity of the non-EPS services, that is, a Mobile Switching Center/Visited Location register (MSC/VLR), and the UE resides in an evolved Universal Terrestrial Radio Access Network (E-UTRAN). When a Circuit Switching (CS) call arrives at the MSC/VLR, if the UE is in an IDLE state, the MSC/VLR pages the UE through the MME, after receiving the paging, the UE firstly executes a Service Request (SR) process, and then a FALL BACK (fallback) completes the call to a 2G/3G system.

When the terminal and the network complete Radio Resource Control (RRC) connection, the terminal and the network side perform an attach procedure, that is, the network side receives a first attach request message sent by the terminal.

It should be noted that, in the embodiment of the present invention, the attach procedure is always initiated by the UE, for example, when the UE is powered on, or when the UE leaves the network coverage for a period of time, the UE needs to re-attach. And the work of the attachment process may include: mutual authentication between the terminal and the network side, and the UE and the MME establish an MME context; the MME establishes a default bearer for the UE; the UE obtains an IP address distributed by the network side; registering terminal position information; assignment of temporary identities, etc. The embodiment form of the UE starting attachment flow is as follows: in the embodiment of the present invention, when connecting with a terminal radio resource control RRC, the network side receives a first attach request message sent by the terminal and starts an attach procedure.

In the embodiment of the present invention, the precondition for executing the attach procedure between the terminal and the network side is that the terminal and the network complete the RRC connection establishment procedure.

Specifically, the terminal sends an RRC connection establishment request message to the network side; the network side returns a response message of RRC connection establishment to the terminal; the terminal sends RRC connection setup complete message to the network side.

Illustratively, (1), the UE REQUESTs establishment of an RRC CONNECTION by sending an RRC CONNECTION REQUEST message RRC CONNECTION REQUEST on the uplink CCCH. (2) The RNC establishes on a dedicated channel at the UE according to the cause of the RRC connection request and the system resource status, and allocates RNTI, radio resources, and other resources (L1, L2 resources). (3) And the RNC sends a RADIO LINK SETUP REQUEST message RADIO LINK SETUP REQUEST to the NodeB to REQUEST the NodeB to allocate specific RADIO LINK resources required by RRC connection. (4) And after the NodeB resource is successfully prepared, responding to a RADIO LINK SETUP RESPONSE message RADIO Link SETUP RESPONSE to the RNC. (5) And the RNC uses an ALCAP protocol to establish the user plane transmission bearer of the Iub interface and completes the synchronization process between the RNC and the NodeB. (6) And the RNC sends an RRC CONNECTION SETUP message RRC CONNECTION SETUP to the UE through a downlink CCCH, wherein the message comprises the information of the special channel distributed by the RNC. (6) And after the UE confirms that the RRC CONNECTION is successfully established, sending an RRC CONNECTION establishment completion message RRC CONNECTION SETUP COMPLETE to the RNC on the uplink DCCH channel which is just established. The RRC connection establishment procedure ends.

S102, when the first attach request message carries a Network Resource Identity (NRI), sending a first attach success message to the terminal.

In the embodiment of the present invention, after receiving a first attach request message sent by a terminal, an LTE base station (specifically, an LTE base station in an emulated network environment, that is, a network side), forwards the first attach request message to an MME (specifically, an MME in an emulated network environment, that is, the network side). The MME authenticates the terminal identification information and the like, while the first attachment request message carries the attachment parameters for performing the attachment process in the embodiment of the invention, when the first attachment request message carries NRI, and when the mobile phone is accessed to a target cell, the LTE base station selects the core network element of the service according to the NIR because the UE carries information such as NRI and the like. When the LTE base station cannot identify the NRI in the first attach request message (i.e., the version of the base station is not compatible with the NRI carried by the terminal), a valid core network element will be randomly selected and the message will be routed to the selected core network element. At this time, because the selection is random, there may be a case that the base station version is incompatible, which may cause the UE to be unable to access the LTE, that is, the related information of the UE may be rejected by the core network, which may cause access failure. Then, here, the MME sends a first attach success message to the terminal through the base station, but a case of network access failure occurs after the attach success.

It should be noted that, in the embodiment of the present invention, since the terminal needs the smsoly characteristic, the problem that the RRC connection is released when the network abnormality occurs after the attach success message is sent to the terminal by the network side is a problem that occurs only when the terminal needs the smsoly characteristic.

It should be noted that smsoly refers to a characteristic of smsoly introduced in 3GPP LTE network proposed by network operators to want their network not to deploy CSFB but to support SMS, and its requirement is to guide LTE UEs requiring voice centric of CS to access through legacy 2G/3G network; the UE requiring the data center is retained in the LTE network and provides the SMS service through the LTE network. Here, the smsoly required UE attaches to EPS services and non-EPS services by performing a joint ATTACH procedure in the LTE system. In the process of associating ATTACH, the UE wants the network side to send smsony support, which indicates that it needs to use EPS services and SMS services. If the network supports smsoly, then in an ATTACH ACCEPT (attach accept, which may also be understood as attach successful) message, the network is indicated to support smsoly. After the attachment is successful, an SGs interface is established between the MME of the EPS services and the MSC/VLR of the non-EPSservices, and the UE resides in the E-UTRAN. When MT-SMS (Mobile terminating-SMS) reaches MSC/VLR, if UE is in IDLE state, MSC/VLR pages UE through MME, UE establishes signaling connection with network after receiving paging, then can receive MT-SMS from MSC/VLR through Non Access Stratum (NAS) signaling message. The UE will not FALL BACK to the 2G/3G network at this time.

In addition, it may also be that the network serving the terminal is the network providing SMSonly, and in this case, when the network side sends the first attach success message, the terminal is informed of the service by carrying the service information supported by the network side in the first attach success message.

In any case, after receiving the first attach request message sent by the terminal, the network side encapsulates the attach result in the first attach success message, where the attach result is used to characterize the access function supported by the network; and the attachment result is used for triggering the terminal to adopt the access function supported by the network to carry out the access process. And then, when detecting that the network abnormity occurs, releasing RRC connection and disconnecting the terminal, sending the first attachment success message to the terminal.

That is, the cause value of the attach result in the attach success message is used to trigger the terminal to perform an access procedure using an access function supported by the network. The cause value in this embodiment may be a result value representing an access function supported by an indication network, and a specific numerical value is not limited in this embodiment.

Exemplarily, if the UE carries an NRI, the network issues an attach success message (a first attach success message), where an attach result carried in the attach success message is an EMM attach request: 'SMS only', here EMM AttachRequlst: 'SMS only' characterizes the network supported access function as a short message function.

S103, when the RRC connection is released, a second attachment request message sent by the terminal is received.

After the network side sends the first attachment success message to the terminal, the network side detects the network abnormity, and when the RRC connection is released, the network side initiates a second attachment request message again to reconnect the network.

In the embodiment of the present invention, after releasing the RRC connection, the network side needs to re-initiate a re-attach procedure within a period of time, so after releasing the RRC connection, the preset timer is started, and before the timing time of the preset timer reaches (i.e. the preset time), the terminal requests the network side to perform an attach procedure again, that is, when releasing the RRC connection, the terminal receives a second attach request message sent by the terminal within the preset time.

Optionally, in the embodiment of the present invention, the preset time may be 30 seconds, and a numerical value of the preset time may be obtained by an actual access network experiment, which is not limited in the embodiment of the present invention.

And S104, when the NRI is not carried in the second attachment request message, sending a second attachment success message to the terminal.

After receiving the second attach request message sent by the terminal, the network side can eliminate the network abnormality caused by incompatibility with the network element version of the network side when the second attach request message does not carry the NRI, so that the second attach success message is sent to the terminal, and the network does not have abnormality any more.

Here, the second attach request message does not carry the NRI, that is, the network side re-initiates the attach request without carrying the NRI, so as to access the LTE network. That is, when the second attach request message does not carry the NRI, a second attach success message is sent to the terminal.

In the embodiment of the present invention, when the second attach request message does not carry an NRI, the second attach request message is sent to the network side again. After receiving a second attach request message sent by the terminal, the network side detects an attach parameter carried by the second attach request message, and when detecting that the attach parameter does not include the NRI, establishes a default EPS bearer (default EPS bearer) for the terminal to complete an attach process, and sends a second attach success message to the terminal.

Here, if the network side detects the attachment parameters carried in the second attachment request message after receiving the second attachment request message sent by the terminal, and when detecting that the attachment parameters still include the NRI, the network side sends a second attachment rejection message to the terminal, and the terminal continues to send a corresponding attach request message to the network again until the network side detects that the attachment parameters do not include the NRI, and successfully completes the attachment process.

And S105, detecting user plane data between the terminal and the LTE network, and accessing the LTE network based on the detection result.

In the embodiment of the invention, after the second attachment success message is sent to the terminal, whether the terminal successfully accesses the LTE network is determined by verifying whether the user plane data between the terminal and the LTE network is smooth.

Specifically, the network side judges whether the rate of user plane data of the terminal in the LTE network is greater than or equal to a preset threshold value; if the rate of user plane data of the terminal in the LTE network is greater than or equal to a preset threshold value, determining that the terminal is successfully accessed into the LTE network; and if the rate of the user plane data of the terminal in the LTE network is less than a preset threshold value, determining that the terminal fails to access the LTE network.

Optionally, the preset threshold in the embodiment of the present invention may be obtained by requirements and practical experiments, and the embodiment of the present invention is not limited.

It can be understood that the terminal executes the access process of the LTE network by using a preset optimization scheme, in this access process, the UE side carries an extra NRI in the attach request message, which is incompatible with the existing base station version, resulting in RRC disconnection, and the UE cannot access LTE.

As shown in fig. 5, the method for detecting a network access result according to the embodiment of the present application includes the following steps:

s201, triggering the UE to initiate an RRC connection Request to the LTE cell, and initiating an Attach Request.

S202, the simulation system checks whether the AttachRequest carries NRI network elements.

S203, if the UE carries NRI, the network issues AttachAccept, wherein the EMM AttachReqult is 'SMS only', then the network abnormally releases RRC connection, and the UE side loses RRC connection.

S204, the simulation system monitors the UE behaviors, whether the AttachRequest can be restarted within the timer1 (preset time) or not is judged, and the AttachRequest does not carry NRI network elements.

S205, if the data passes the optimization scheme, the optimization scheme is successful, otherwise, the optimization scheme fails; if the user interface data is successful, the simulation system establishes defaultEPSBearer in a matching way, and verifies that the user interface data is smooth.
