Detailed Description

With the above figures, certain embodiments of the invention have been illustrated and described in more detail below. The drawings and the description are not intended to limit the scope of the inventive concept in any way, but rather to illustrate it by those skilled in the art with reference to specific embodiments.

Fig. 1 is a schematic structural diagram of a network system according to an embodiment of the present invention. As shown in fig. 1, the network system includes a plurality of base stations 11, a plurality of user terminals 12, and a core network device 13. The base station 11 is configured to manage or support one or more cells, and select one cell to initiate access when the terminal 12 needs to perform a voice call service. After accessing the cell of the base station 11, the terminal 12 establishes communication with one or more core networks 13 to implement a voice call service. Wherein the core network 13 establishes a connection with one or more base stations 11.

The current voice call service mainly comprises three links: an access link, a maintenance link and a hang-up link. In the process of voice call service, the main factors influencing the voice call quality include: access/hang-up delay, quality of call hold, probability of call drop during call, etc. In the existing voice call service, the user has obvious feeling on the waiting time of the access link, and the time delay of the access link directly influences the call service experience of the user. However, in the existing voice call service, the data transmission overhead for realizing the access link between the terminal 12 and the base station 11 is too large, which results in too long time delay of the access link in the voice call service, and thus causes too long waiting time of the user in the dialing call process, which directly affects the voice call service experience of the user.

In order to avoid the technical problem, the access link of the voice call service is optimized, and after the base station is set to send the RRC connection establishment request, the RNC is set to generate a configuration instruction for establishing the RRC connection according to the RRC connection request, so that the base station establishes radio resource control connection with the terminal according to the configuration parameters. By setting that the configuration instruction does not contain the terminal capability parameter, the terminal returns the corresponding configuration parameter according to the configuration instruction and does not contain the terminal capability parameter, the data volume transmitted between the terminal and the base station is reduced, the data transmission performance is improved, and the data transmission delay is reduced.

Fig. 2 is a first flowchart of a voice call quality optimization method according to an embodiment of the present invention. The main execution body of the method of this embodiment may be the terminal in fig. 1, as shown in fig. 2, the voice call quality optimization method includes the following steps:

s201: and sending a request for establishing Radio Resource Control (RRC) connection to the base station, wherein the RRC connection request is used for indicating the base station to generate a configuration instruction for establishing the RRC connection according to the RRC connection request, and the configuration instruction does not contain a terminal capability parameter.

In the idle mode, after the terminal is powered on, cell selection is immediately performed, and after the terminal completes cell synchronization, a request for establishing Radio Resource Control (RRC) connection is sent to the base station. The establishment of the RRC Connection is a precondition that the terminal performs signaling interaction with the network, when the terminal is in an idle state without the RRC Connection, if an upper layer of the terminal requires the establishment of the RRC signaling Connection, the terminal starts a procedure of establishing the RRC Connection, and the terminal sends an RRC Connection Request to the base station, that is, sends an RRC Connection Request message to the base station. The signaling parameters of the RRC Connection Request message are shown in table 1.

TABLE 1

In the embodiment of the invention, the base station generates the configuration instruction for establishing the RRC connection according to the RRC connection request sent by the terminal, and the configuration instruction does not contain the terminal capability parameter, namely the configuration instruction sets the UE capability indication parameter as default, thereby reducing the data transmission overhead of the configuration instruction, improving the transmission rate and reducing the data transmission delay.

In a specific embodiment, the base station is a radio network controller RNC, and the terminal capability parameter is specifically a terminal capability update parameter. The base station is composed of a Radio Network Controller (RNC) and a NodeB, the RNC is responsible for mobility management, call processing, link management and handover mechanisms, the NodeB is interconnected with the RNC through a standard Iub interface, and communicates with a terminal through a Uu interface, and mainly completes processing of a Uu interface physical layer protocol and an Iub interface protocol. After receiving the request for establishing the RRC Connection sent by the terminal, the RNC selects whether to establish the RRC Connection on the dedicated channel or the common channel, prepares resources corresponding to the dedicated channel or the common channel, and generates a configuration instruction according to the request for establishing the RRC Connection, namely generates an RRC Connection Setup message. The configuration instruction does not include the capability parameter of the terminal UE. As shown in table 2, the signaling parameters of the RRC Connection Setup message do not include a Capability update requirement parameter, that is, the configuration instruction does not set a specific terminal Capability update parameter configuration requirement that the network proposes to the terminal UE.

TABLE 2

In a specific embodiment, the base station is an evolved Node B, and the terminal capability parameter is a terminal extended service request parameter. An evolved Node B, eNB for short, is the name of a base station in a Long Term Evolution (Long Term Evolution, LTE for short) network. Compared with the Node B in the existing 3G, the eNB integrates partial functions of the RNC, reduces the protocol level during communication and is responsible for all functions related to an air interface. When the base station is an eNB, that is, the current network is an LTE network. When an LTE network processes a Voice Call service, two modes, namely, a Call Session Control Function (CSCF) Voice solution and a Voice over IP (VoIP) Voice transmission, are generally adopted. Generally, before IMS technology is commercially used, CFCS technology is used to temporarily provide CS access, so that resources of an existing CE network can be effectively utilized. When the CSCF technology is used to implement CS voice call service, the terminal sends a request for establishing Radio Resource Control (RRC) connection to the base station, and the base station generates a configuration instruction. The configuration instruction does not include a capability parameter of the terminal UE, that is, the configuration instruction does not set an Extended Service Request (ESR) parameter.

S202: and receiving the configuration instruction sent by the base station, and generating an RRC connection establishment completion instruction according to the configuration instruction, wherein the configuration parameters carried by the RRC connection establishment completion instruction do not include terminal wireless access capability parameters.

In the embodiment of the present invention, the terminal generates the corresponding configuration parameters according to the configuration set in the configuration instruction sent by the base station, that is, when the configuration instruction does not include the terminal capability parameter, the configuration parameters generated by the terminal do not include the terminal wireless access capability parameter. And the terminal generates an RRC connection establishment completion instruction according to the configuration instruction, wherein the RRC connection establishment completion instruction carries configuration parameters which do not contain the wireless access capability parameters of the terminal. The terminal wireless access capability parameter is used for representing a network version supported by terminal hardware, a terminal level defining transmission capability between the base station and the terminal, a channel capability of the terminal, a radio frequency capability of the terminal and the like.

Illustratively, when the base station is a radio network controller RNC, the terminal generates a corresponding RRC Connection Setup Complete command according to a configuration command sent by the base station, where the RRC Connection Setup Complete command signaling message carries configuration parameters that do not include the terminal radio access capability parameters. As shown in table 3, table 3 shows the specific data frame contents of the configuration parameters in the RRC Connection Setup Complete command. Because the configuration command does not include the terminal capability parameter, correspondingly, the configuration parameter carried by the RRC Connection Setup Complete command returned by the terminal does not include the UR radio access capability parameter.

TABLE 3

For example, when the base station is an eNB, the RRC Connection Setup Complete signaling message does not include a UE _ RAT Specific Capability parameter, mainly refers to an EUTRA _ Radio Access Capability. The terminal will normally report information whether the UE supports the format of the access network as frequency division duplex or time division duplex, whether handover is supported, whether measurement is supported, and the LTE frequency band supported in the compressed mode. And indicating whether the terminal supports the measurement terminal capability of the access network by setting a second bit from the left of a Feature Group indicator (FGI for short). For example, if the terminal sets the access network FGI to f0, the transition is to be 11110000 in binary, and the second leftmost bit is 1, which indicates that the terminal supports the measurement capability of the access network.

S203: and sending the RRC connection establishment completion instruction to the base station so as to establish RRC connection between the terminal and the base station.

The terminal sends an RRC connection establishment completion instruction to the base station to indicate that the RRC connection establishment between the terminal and the base station is completed, and the terminal can perform data interaction through the attached base station to realize voice call service or data service. The configuration parameters carried by the RRC connection establishment completion instruction returned by the terminal do not contain the terminal wireless access capability parameters, and the base station can allocate appropriate resources and algorithms to the terminal according to the configuration parameters returned by the terminal.

In the configuration parameters carried by the command for completing establishing the RRC connection, the proportion of the length of the data frame of the wireless access capability parameter of the terminal to the whole configuration parameters is large, so that the time delay of the data transmission of the configuration parameters between the terminal and the base station is large, and the configuration parameters of the command for completing the RRC connection can be set to be free from the wireless access capability parameter of the terminal, so that the data transmission overhead is saved, and the time delay is reduced.

It can be seen from the foregoing embodiments that, after a terminal sends a request for establishing RRC connection for controlling radio resources to a base station, the base station generates a configuration instruction for establishing RRC connection according to the RRC connection request, and the terminal generates a command for completing establishment of RRC connection according to the configuration instruction and sends the command for completing establishment of RRC connection to the base station, where configuration parameters included in the command for completing establishment of RRC connection do not include terminal radio access capability parameters, and by setting that the configuration parameters do not include terminal capability parameters and the configuration parameters do not include terminal radio access capability parameters, data overhead of signaling transmission when RRC connection is established between the base station and the terminal is reduced, time delay caused by an excessively long signaling length for establishing RRC connection is reduced, an RRC establishing speed between the terminal and the terminal is increased, and user experience of using voice services is improved.

Fig. 3 is a flowchart of a voice call quality optimization method according to an embodiment of the present invention. When the base station is an RNC, as shown in fig. 3, the method for optimizing the voice call quality further includes the following steps:

s301: receiving a called pre-ringing request sent by the RNC, wherein the called pre-ringing request is generated by the RNC according to a called voice service establishment request, and the called voice service establishment request is sent to the RNC by a receiving Mobile Switching Center (MSC).

In the called process, firstly, a mobile switching center MSC sends a called voice service establishment request to an RNC, the RNC generates a called pre-ringing request according to the called voice service establishment request and sends the called pre-ringing request to a terminal, so that the terminal performs called response according to the called pre-ringing request. Illustratively, the RNC enables the terminal to respond to the called in time and return a ringing response according to the called pre-ringing request by setting the called pre-ringing request. The RNC sets the Boolean value of UExtRncInfo.rncSetupOpForAlertSw to be 1, and sets the Signal IE of the Setup message of the called downlink NAS layer to be filled in as UExtRncInfo.rncSetupSigValue in the process of establishing the called voice service, and the RNC sets the Signal ID through the Signal IE of the Setup message.

S302: and simultaneously sending a dialing confirmation message and a ringing message to the RNC according to the called pre-ringing request.

After receiving a called pre-ringing request sent by the RNC, the terminal parses the signaling of the called pre-ringing request, and returns a dialing confirmation message and a ringing message at the same time according to the result of the parsing, specifically, the called pre-ringing request is a Setup message sent to the terminal by the RNC at a called downlink non-access layer. Illustratively, when the terminal recognizes that the boolean value of uextrnclnfo. rncsetupopforalert sw is 1 in the parsed called pre-ringing request, a dial confirmation message and a ringing message are returned to the RNC in response to the called service. Illustratively, in the process of establishing the called voice service, the RNC fills in the Signal IE parameter of the Setup message to trigger the terminal to send a ringing message in advance while returning a dialing confirmation message, thereby reducing the waiting time between the dialing confirmation message and the ringing message in the called process.

In the embodiment of the invention, the terminal is set to simultaneously return the dialing confirmation message and the ringing message according to the analyzed result, so that the waiting time between the dialing confirmation message and the ringing message in the called process is reduced, namely the current CSFB delay is the calling delay minus the called delay, the CSFB delay is obviously reduced, and the user experience is improved.

It can be known from the above embodiments that, by setting the called pre-ringing request, the RNC enables the terminal to respond to the called and return ringing responses in time according to the called pre-ringing request, and when the dialing confirmation message is returned, the ringing message is returned, which reduces the time delay between the dialing confirmation message being returned and the ringing message being returned, improves the efficiency of the called in the voice call service, and improves the user experience.

Fig. 4 is a flowchart of a voice call quality optimization method provided in the embodiment of the present invention. When the base station is an RNC, as shown in fig. 4, the method for optimizing the voice call quality further includes the following steps:

s401: receiving a first radio bearer establishment request sent by the RNC, wherein the first radio bearer establishment request is generated by the RNC according to a voice service configuration request which is sent to the RNC by a Mobile Switching Center (MSC).

In the process of establishing the voice call service, firstly, a Mobile Switching Center (MSC) sends a voice service configuration request to an RNC (radio network controller), the RNC generates a first wireless bearer establishment request for executing the voice service after receiving the voice service configuration request, and sends the first wireless bearer establishment request to a terminal, so that the terminal establishes the voice service according to the first wireless bearer establishment request.

Illustratively, the core network device includes a Mobile Switching Center (MSC), a Serving GPRS Support Node (SGSN), and a Gateway GPRS Support Node (GGSN). The MSC is used to implement voice call service, complete functions such as call connection, handoff control, radio channel management, etc., and is also an interface device for fixed networks such as mobile networks and public switched telephone networks, integrated services digital networks, etc.

S402: and configuring a voice service resource block according to the first radio bearer establishment request, generating a first establishment completion response according to the first radio bearer establishment request, and sending the first establishment completion response to the RNC, so that the RNC generates a voice service configuration response according to the first establishment completion response, and establishes a voice service with the MSC according to the voice service configuration response.

The terminal establishes the requested voice service resource block according to the first radio bearer and generates a first establishment completion response, namely the current terminal and the RNC realize voice call service communication. And the terminal sends the first establishment completion response to the RNC so that the RNC generates a voice service configuration response according to the first establishment completion response and establishes the voice service with the MSC according to the voice service configuration response, namely the RNC establishes voice communication service communication with the MSC. At this time, the terminal accesses the core network MSC through the RNC, and establishes the voice call service.

S403: and configuring the data service resource block according to a second radio bearer establishment request, wherein the second radio bearer establishment request is generated by the RNC according to the data service configuration request, and the data service configuration request is sent by a serving GPRS support node SGSN.

In the process of establishing the data service, firstly, a Mobile Switching Center (MSC) sends a data service configuration request to an RNC, the RNC generates a second radio bearer establishment request for executing the data service after receiving the data service configuration request, and sends a first radio bearer establishment request to a terminal, so that the terminal establishes the data service according to the first radio bearer establishment request, wherein the data service configuration request is sent by a Serving GPRS Support Node (SGSN). Illustratively, the SGSN, as an important component of a packet domain device of a core network of a mobile communication network, mainly completes functions of routing forwarding, mobility management, session management, logical link management, authentication and encryption, ticket generation and output, and the like of a packet data packet. In the process of establishing the data service, the SGSN data service configuration request is sent to the RNC to establish the data service.

S404: and if the configuration of the data service resource block according to the second radio bearer establishment request fails, generating a second establishment failure response, and sending the second establishment failure response to the RNC, so that the RNC sends a request signaling for establishing radio link reconfiguration to the NodeB.

If the terminal has already established the voice call service, the second radio bearer establishment request for establishing the data service is received for configuring the data service resource block, that is, the terminal has established the voice call service and the data service at the same time, that is, the terminal needs to process the voice call service and the data service at the same time. In the prior art, when a terminal processes a voice call service and a data service simultaneously, and when the terminal fails to configure a data service resource block according to a second radio bearer setup request, a second setup failure response is generated and sent to an RNC, and the RNC releases an RRC connection for the voice call service, which is established between the RNC and the terminal, according to the second setup failure response, that is, the voice call service is dropped.

In the embodiment of the invention, in order to avoid the problem of call drop when the terminal processes the voice call service and the data service at the same time, the RNC reconfigures the RL link according to the second establishment failure response, namely sends a radio link reconfiguration preparation message to the NodeB, deletes the relevant configuration information of the data service and ensures the normal data communication of the voice service.

It can be seen from the foregoing embodiments that, when the terminal processes the voice call service and the data service at the same time, the RNC reconfigures the RL link according to the second establishment failure response, that is, sends a radio link reconfiguration preparation message to the NodeB, and deletes the relevant configuration information of the data service, thereby ensuring normal call of the voice service, reducing call drop rate during concurrent service, and improving user experience in using the voice call service.

In the embodiment of the invention, the base station acquires the Received Signal Code Power (RSCP) of a radio resource control connection signal established by the RNC and the terminal and a service scene established by the base station and the terminal. Specifically, RSCP represents CPICH-one-codeword power. The service scene is divided into an RRC establishment scene and a CS service establishment triggering scene, wherein the CS service establishment triggering scene specifically refers to a migration process from CELL _ FACH/PCH to CELL _ DCH.

S503: and adjusting the rate of the Signaling Radio Bearer (SRB) according to the Ec/No index, the Received Signal Code Power (RSCP) and the service scene.

Illustratively, when the service scenario is an RRC establishment scenario, and the user uses a data service, the requirement on data transmission delay is not high. On one hand, if the Ec/No index is greater than a first preset index and the RSCP is greater than a first preset RSCP parameter, it indicates that the current signal coverage is strong coverage, so that the rate of the SRB of the D/D channel during RRC establishment can be adjusted to a first parameter, that is, a high rate parameter, and the rate of RRC access is increased. Specifically, the first parameter comprises a time domain of 13.6kbps and a step size of 27.2 kbps. On the other hand, if the Ec/No index is smaller than the first preset index or the RSCP is smaller than the first preset RSCP parameter, the SRB rate is adjusted to a second parameter, which indicates that the current signal coverage is medium signal coverage strength or weak coverage strength, and the SRB rate of the D/D channel during RRC establishment can be adjusted to the second parameter, i.e., a medium rate parameter, so as to avoid resource waste. Specific second parameters include a time domain of 3.4kbps and a step size of 4.8 kbps.

When the service scene is a CS service establishment scene, that is, when a terminal in a CELL _ FACH/PCH state initiates a voice call service, if the data transmission rate is too low, the voice call delay is too long, and the call experience of the user is directly affected. On one hand, if the Ec/No index is greater than a first preset index or the RSCP is greater than a first preset RSCP parameter, it indicates that the current signal coverage is strong coverage, so the rate of the SRB of the voice call service can be adjusted to a first parameter, i.e., a high-rate parameter, for improving the data transmission rate of the voice call service, and if the data transmission rate is too low, the delay of the voice call is too large, which directly affects the call experience of the user. On the other hand, if the Ec/No index is smaller than a second preset index or the RSCP is smaller than a second preset RSCP parameter, it indicates that the current signal coverage is medium signal coverage strength or weak coverage strength, and the rate of the SRB of the voice call service may be adjusted to a second parameter, that is, a medium rate parameter, so as to avoid resource waste.

It can be known from the above embodiments that the radio resource bearer access rate is dynamically adjusted according to the signal coverage strength and the service type, and if the service type is a voice service, the high-rate radio resource bearer access rate is set, so as to reduce the time delay of the voice service; and when the service type is data service, setting a low-rate wireless resource bearing access rate to ensure the success rate of the data service. Resource waste caused by the fact that the radio resource which is uniformly set to be the high speed bears the access speed is avoided, time delay in the voice call service is reduced, and experience of a user in using the voice call service is improved.

In one embodiment, a pilot channel strength and a received signal strength indication of a forward access channel are obtained, and a maximum transmit power of the forward access channel is adjusted according to the pilot channel strength and the received signal strength indication.

And acquiring pilot channel strength RSCP of the FACH channel and received signal strength indicator RSSI, and acquiring an Ec/No index optimized by the wireless network according to the RSCP and the RSSI. Where Ec/No is used to indicate the total received power of the terminal, i.e. the strength of all useful signals and interference signals currently received by the handset.

In the embodiment of the invention, the maximum transmitting power of the forward access channel is adjusted according to the pilot channel strength and the received signal strength indication, when the quality of Ec/No is better, the maximum transmitting power of the forward access channel is reduced, and when the quality of Ec/No is worse, the maximum transmitting power of the forward access channel is improved. Illustratively, when the value of Ec/No is less than or equal to a preset threshold, the maximum transmit power of the FACH channel is increased according to a preset percentage, and when the value of Ec/No is greater than the preset threshold, the maximum transmit power of the FACH channel is decreased according to the preset percentage, and the transmit power of the FACH channel is dynamically updated.

It can be known from the foregoing embodiments that the maximum transmit power of the forward access channel is adjusted according to the pilot channel strength and the received signal strength indication, and the transmit power of the FACH channel is dynamically updated, so as to achieve the purpose of improving the radio resource control access success rate and improving the call reestablishment success rate, and improve the quality of the voice service.
