Detailed Description

Specific embodiments of the present invention have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the 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 a cell to initiate access when the terminal 12 needs to perform a voice call service. After the terminal 12 accesses the cell of the base station 11, communication is established 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 holding link and a hanging-up link. In the process of voice call service, main factors affecting voice call quality include: access/hang-up delay, quality while maintaining call, probability of dropped calls during call, etc. In the existing voice call service, the waiting time of the user for the access link is obviously felt, 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 implementing 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, 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 problems, the invention optimizes the access link of the voice call service, and after setting the RRC connection establishment request sent by the base station, 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 the capability parameters of the terminal which are not included in the configuration instruction, the terminal returns the capability parameters of the terminal which are not included in the corresponding configuration parameters according to the configuration instruction, so that the data volume of transmission between the terminal and the base station is reduced, the data transmission performance is improved, and the time delay of data transmission is reduced.

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

s201: and sending a Radio Resource Control (RRC) connection establishment request 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 terminal capability parameters.

In idle mode, after the terminal is started, the terminal immediately executes cell selection, and after the terminal completes cell synchronization, the terminal sends a request for establishing radio resource control (Radio Resource Control, abbreviated as RRC) connection to the base station. The establishment of the RRC connection is a precondition that the terminal performs signaling interaction with the network, and 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 a 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 is set to not contain the terminal capability parameter, namely UE capability indication parameter is set as default in the configuration instruction, so that the data transmission overhead of the configuration instruction is reduced, the transmission rate is improved, and the data transmission delay is reduced.

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 (Radio Network Controller, RNC for short) and a NodeB, the RNC is used for being responsible for mobility management, call processing, link management and handover mechanism, the NodeB is interconnected with the RNC through a standard Iub interface, and is communicated with the terminal through a Uu interface, and the processing of a Uu interface physical layer protocol and an Iub interface protocol is mainly completed. 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 on 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, that is, generates a RRC Connection Setup message. Wherein, the configuration instruction does not contain the capability parameters of the terminal UE. As shown in table 2, the signaling parameters of the RRC Connection Setup message do not include Capability update requirement parameters, that is, the configuration instruction does not set the network to propose corresponding specific terminal capability update parameter configuration requirements to the terminal UE.

TABLE 2

In a specific embodiment, the base station is an evolved Node B, and the terminal capability parameter is specifically a terminal extended service request parameter. An evolved Node B, abbreviated eNB, is the name of a base station in a long term evolution (Long Term Evolution, abbreviated LTE) network. Compared with Node B in the existing 3G, eNB integrates the functions of partial RNC, reduces the protocol level in communication and is responsible for all functions related to air interface. When the base station is an eNB, i.e. the current network is an LTE network. LTE networks typically employ either a call session control function (Call Session Control Function, CSCF for short) voice solution or voice over IP (Voice over Internet Protocol, voIP for short) when handling voice call traffic. Generally, before IMS technology is commercially available, CFCS technology is adopted to temporarily provide CS access, so that resources of an existing CE network can be effectively utilized. When the CS voice call service is realized by using the CSCF technology, the terminal sends a request for establishing radio resource control (Radio Resource Control, RRC for short) 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 a terminal extended service request parameter (Extended service request, ESR for short).

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 parameter carried by the RRC connection establishment completion instruction does not contain a terminal wireless access capability parameter.

In the embodiment of the invention, the terminal generates the corresponding configuration parameters according to the configuration set in the configuration instruction sent by the base station, namely, when the configuration instruction does not contain the terminal capability parameters, the terminal wireless access capability parameters are not contained in the configuration parameters generated by the terminal. 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 network version supported by terminal hardware, terminal grade defining transmission capability between a base station and a terminal, channel capability of the terminal, radio frequency capability of the terminal and the like.

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

TABLE 3 Table 3

For example, when the base station is an eNB, the RRC Connection Setup Complete signaling message does not include the ue_ RAT Specific Capability parameter, mainly refers to an eutra_radio Access Capability parameter, and the parameter mainly includes information such as a frequency band and CA Capability of a Radio Access network supported by the UE. The terminal can report information whether the format of the access network is frequency division duplex or time division duplex, whether the UE supports switching, whether the UE supports measurement, LTE frequency bands supported in a compressed mode and the like normally. By setting the second bit from the left of the access network function group indicator (Feature Group Indicators, FGI for short), it is indicated whether the terminal supports the measurement terminal capability of the access network. For example, if the terminal sets the access network FGI to f0, it is converted to binary 11110000, 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 the RRC connection between the terminal and the base station.

The terminal sends an RRC connection establishment completion instruction to the base station, which indicates that the RRC connection establishment between the terminal and the base station is completed, and the terminal can implement 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 wireless access capability parameters of the terminal, and the base station allocates proper resources and algorithms for the terminal according to the configuration parameters returned by the terminal.

In the configuration parameters carried by the RRC connection completion instruction, the data frame length of the terminal wireless access capability parameter occupies a larger proportion of the whole configuration parameters, so that the time delay of the configuration parameters for carrying out data transmission between the terminal and the base station is larger.

As can be seen from the above embodiment, after the terminal sends the RRC connection establishment request to the base station, the base station generates a configuration instruction for establishing RRC connection according to the RRC connection request, and the terminal generates an RRC connection establishment completion instruction according to the configuration instruction and sends the RRC connection establishment completion instruction to the base station, where the configuration parameter included in the RRC connection establishment completion instruction does not include a terminal radio access capability parameter, and by setting the configuration parameter included in the configuration instruction does not include a terminal radio access capability parameter, the data overhead of signaling transmission when the RRC connection is established between the base station and the terminal is reduced, time delay caused by excessively long signaling length for establishing RRC connection is reduced, speed of establishing RRC between the terminal and the terminal is improved, and user experience of using voice service 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 voice call quality optimization method further includes the steps of:

s301: and 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 of the terminal, 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 the terminal, so that the terminal responds to the called according to the called pre-ringing request. The RNC illustratively causes the terminal to respond to the called call in time and return a ringing response in accordance with the called pre-ringing request by setting the called pre-ringing request. The RNC sets the Signal ID by setting the Boolean value of the UExtRncInfo. RncSetupOpForAlertSw to 1, and setting the Signal IE of the Setup message of the called downlink NAS layer to be UExtRncInfo.rncSetupSigValue, RNC through the Signal IE of the Setup message in the called voice service establishment process.

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

After receiving the called pre-ringing request sent by the RNC, the terminal analyzes the signaling of the called pre-ringing request, and simultaneously returns a dialing confirmation message and a ringing message according to the analysis result, 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 uextrncinfo. Rncstupopfort is 1 in the parsed called pre-ringing request, a dial confirmation message and a ringing message are returned to the RNC when responding to the called service. In the process of establishing the called voice service, the RNC fills in the Signal IE parameters of the Setup message to trigger the terminal to send the ringing message in advance while returning the 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 analysis result, so that the waiting time between the dialing confirmation message and the ringing message in the called process is reduced, namely the time delay of the current CSFB is the calling time delay minus the called time delay, the time delay of the CSFB is obviously reduced, and the user experience is improved.

According to the embodiment, the RNC sets the called pre-ringing request, so that the terminal responds to the called and returns ringing response in time according to the called pre-ringing request, and returns ringing message while returning dialing confirmation message, so that the time delay between the dialing confirmation message and the ringing message is reduced, the called efficiency in voice call service is improved, and the user experience is improved.

Fig. 4 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. 4, the voice call quality optimization method further includes the steps of:

s401: and 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, and the voice service configuration request is sent to the RNC by a mobile switching center MSC.

In the process of establishing voice call service, firstly, a mobile switching center MSC sends a voice service configuration request to an RNC, after the RNC receives the voice service configuration request, a first radio bearer establishment request for executing voice service is generated, and the first radio bearer establishment request is sent to a terminal, so that the terminal establishes voice service according to the first radio bearer establishment request.

The core network equipment illustratively includes a mobile switching center (Mobile Switching Center, MSC for short), a serving general packet radio service support node (Serving GPRS Support Node, SGSN for short), and a gateway general packet radio service support node (Gateway GPRS Support Node, GGSN for short). The MSC is used for realizing voice call service, completing call connection, cell switching control, wireless channel management and other functions, and is also an interface device of a mobile network and a public switched telephone network, a comprehensive service digital network and other fixed networks.

S402: the method comprises the steps of configuring a voice service resource block according to a 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 an RNC, so that the RNC generates a voice service configuration response according to the first establishment completion response, and establishing voice service with the MSC according to the voice service configuration response.

The terminal establishes a request voice service resource block according to the first wireless bearing and generates a first establishment completion response, namely the current terminal has realized voice call service communication with the RNC. 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 voice service with the MSC according to the voice service configuration response, namely, the RNC establishes voice call service communication with the MSC. At this time, the terminal has realized accessing core network MSC through RNC, has set up the voice call service.

S403: the data traffic resource blocks are configured according to a second radio bearer setup request, wherein the second radio bearer setup request is generated by the RNC according to the data traffic configuration request, which is sent by the 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. The SGSN is an important component of a mobile communication network core network packet domain device, and mainly performs functions of packet data packet routing forwarding, mobility management, session management, logical link management, authentication and encryption, call ticket generation and output, and the like. In the process of establishing the data service, an SGSN data service configuration request is sent to an RNC to establish the data service.

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

If the terminal has established the voice call service and receives a second radio bearer establishment request for establishing the data service for configuring the data service resource block, the terminal establishes the voice call service and the data service at the same time, i.e. 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 at the same time, the terminal generates a second establishment failure response when the terminal fails to configure a data service resource block according to a second radio bearer establishment request, and sends the second establishment failure response to an RNC, and the RNC releases an RRC connection for the voice call service established between the terminal and the terminal according to the second establishment failure response, namely, the voice call service has a dropped call condition.

In the embodiment of the invention, in order to avoid the problem of dropped call when the terminal processes the voice call service and the data service simultaneously, the RNC performs RL link reconfiguration according to the second establishment failure response, namely, sends a wireless 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.

As can be seen from the above embodiment, when the terminal processes the voice call service and the data service at the same time, the RNC performs RL link reconfiguration according to the second setup failure response, that is, sends a radio link reconfiguration preparation message to the NodeB, deletes relevant configuration information of the data service, ensures normal call of the voice service, reduces call drop rate when the voice service is concurrent, and improves user experience when using the voice call service.

Fig. 5 is a flowchart of a voice call quality optimization method according to an embodiment of the present invention. The main implementation body of the method of this embodiment may be the base station in fig. 1, and when the base station is an RNC, as shown in fig. 5, the voice call quality optimization method further includes the following steps:

s501: and obtaining an Ec/No index according to the pilot channel strength of the forward access channel and the received signal strength indication.

In the embodiment of the invention, a base station acquires the pilot channel strength RSCP of the FACH channel and the received signal strength indication RSSI, and acquires the Ec/No index of wireless network optimization according to the RSCP and the RSSI. The Ec/No is used to indicate the total power received by the terminal, i.e. the intensity of all the useful signals and interference signals currently received by the mobile phone.

S502: and acquiring the received signal code power RSCP and service scene of the radio resource control connection signal established between the RNC and the terminal.

In the embodiment of the invention, the base station acquires the received signal code power RSCP of the radio resource control connection signal established by the RNC and the terminal, and the 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.

In the embodiment of the invention, the coverage intensity of the current wireless signal is determined according to the Ec/No index and the received signal code power RSCP, and the rate of SRB is adjusted according to the interaction scene between the current terminal and the base station, so that the success rate of RRC access is improved and the resource waste is avoided.

For example, when the service scenario is an RRC setup scenario, the requirements for data transmission delay are not high when the user is using the data service. On the one hand, if the Ec/No index is greater than the first preset index and the RSCP is greater than the 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 the first parameter, i.e., the high rate parameter, so as to increase the rate of RRC access. Specifically, the first parameter includes a time domain of 13.6kbps and a step size of 27.2kbps. 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 rate of the SRB is adjusted to the second parameter, which means that the current signal coverage is medium signal coverage strength or weak coverage strength, so that the rate of the SRB of the D/D channel can be adjusted to the second parameter, that is, the medium rate parameter, when the RRC is established, thereby avoiding resource waste. The second parameter specifically includes a time domain of 3.4kbps and a step size of 4.8kbps.

When the service scene is a CS service establishment scene, namely when a terminal in a CELL_FACH/PCH state initiates a voice call service, if the data transmission rate is too low, the time delay of the voice call is too high, and the call experience of a user is directly affected. On the one hand, if the Ec/No index is greater than the first preset index or the RSCP is greater than the first preset RSCP parameter, it indicates that the current signal coverage is strong coverage, so that the rate of the SRB of the voice call service can be adjusted to be the first parameter, that is, the 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, so as to directly affect the call experience of the user. On the other hand, if the Ec/No index is smaller than the second preset index or the RSCP is smaller than the second preset RSCP parameter, it is indicated that the current signal coverage is of medium signal coverage strength or weak coverage strength, and the rate of the SRB of the voice call service can be adjusted to the second parameter, that is, the medium rate parameter, so that resource waste is avoided.

As can be seen from the above embodiments, the radio resource bearer access rate is dynamically adjusted according to the strength of signal coverage and the service type, if the service type is voice service, the radio resource bearer access rate with high rate is set, and the time delay of the voice service is reduced; and when the service type is data service, setting a radio resource bearing access rate of low rate, and ensuring the success rate of the data service. The resource waste caused when the radio resource bearing access rate is uniformly set to be high is avoided, the time delay in the voice call service is reduced, and the experience of the user for 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 based on the pilot channel strength and the received signal strength indication.

In the embodiment of the invention, a forward access channel, namely a FACH channel, is acquired and used for transmitting a downlink transmission channel of control information to a terminal located in a cell, namely the channel is used after a base station receives a random access message. And acquiring pilot channel strength RSCP and received signal strength indication RSSI of the FACH channel, and acquiring an Ec/No index of wireless network optimization according to the RSCP and the RSSI. The Ec/No is used to indicate the total power received by the terminal, i.e. the intensity of all the useful signals and interference signals currently received by the mobile phone.

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

According to the above embodiment, the maximum transmitting power of the forward access channel is adjusted according to the pilot channel strength and the received signal strength indication, and the transmitting power of the FACH channel is dynamically updated, so that the purposes of improving the success rate of controlling access of radio resources and improving the success rate of call reestablishment are achieved, and the quality of voice service is improved.

In a specific embodiment, a service type of establishing radio resource control connection between the RNC and the terminal is obtained, and if the service type is a voice service, uplink transmission power of the terminal and signal quality of an optimal cell can be obtained, and a soft handover area range of the RNC is enlarged according to the uplink transmission power and the signal quality of the optimal cell. The updated soft handoff region range is calculated through the uplink transmitting power and the signal quality of the optimal cell, so that the coverage range of the voice service is enlarged, the data transmission success rate of the voice service is ensured, and the time delay of the voice service is reduced.
