Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The LTE random access control method provided by the embodiment of the invention can be applied to the environment shown in figure 1. Referring to fig. 1, a terminal 102 supporting LTE establishes a connection with a base station 104 through an LTE random access procedure, and then accesses an LTE network. The base station refers to a public mobile communication base station, and information can be transmitted between a mobile communication switching center and a mobile phone terminal in a certain radio coverage area. LTE (Long Term Evolution) is a Long Term Evolution of The UMTS (universal mobile Telecommunications System) technical standard established by The 3GPP (The 3rd generation Partnership Project) organization.
The LTE random access is a first step of communication between user equipment and an LTE network after downlink synchronization is completed through mapping of a primary synchronization sequence and a secondary synchronization sequence in mobile communication. In an LTE system, a UE (User Equipment, terminal) needs to perform downlink synchronization before communicating with an eNodeB (evolved node B, base station in LTE), and uplink synchronization is further completed on the basis of the downlink synchronization, that is, LTE random access is performed.
In one embodiment, as shown in fig. 2, an LTE random access control method is provided, including:
The terminal supporting LTE is started or plugged, and the modem receives the system message sent by the base station.
Step 220, the terminal starts a network searching process according to the system message to acquire the base station to be connected.
The terminal starts a network searching process according to the system information, specifically, the terminal firstly performs physical downlink synchronization, performs cell selection by searching measurement, and resides and starts an attach process after selecting a suitable and acceptable cell. Generally, one base station covers multiple cells, so that when a terminal finds a suitable cell, the base station corresponding to the cell is obtained, and the base station is a base station to which the terminal is connected.
And step 230, the terminal establishes connection with the base station through the LTE random access process to access the LTE network, if the access fails, the terminal judges the network condition of the LTE network to be accessed currently, and if the network condition of the LTE network meets a preset network environment, the terminal resets the time length of a timer in the LTE random access process.
The terminal establishes connection with the base station through an LTE random access process to access the LTE network, and specifically, the terminal sends a random access request signaling to the base station, the base station sends a random access signaling to the terminal after configuring a signaling bearer SRB1 for the terminal, the terminal receives the random access signaling and completes SRB1 bearer and wireless resource configuration with the base station, and then feeds back a random access completion signaling to the base station, so that the terminal is accessed to the LTE network. However, if the terminal timer does not receive the random access signaling sent by the base station within the set time length, the access fails. After the access fails, the terminal judges the network condition of the LTE network to be accessed currently, and if the network condition of the LTE network meets the preset network environment, the terminal resets the time length of the timer in the LTE random access process. For example, when the preset network environment where the terminal is located is a strong Signal environment, for example, the current Signal is a full cell or LTE RSRP (Reference Signal Receiving Power) > -96dBm is a strong Signal, the terminal extends the time duration of the timer in the LTE random access process. When the preset network environment where the terminal is located is a weak Signal environment, that is, the current Signal is not a full or LTE RSRP (Reference Signal Receiving Power) < -96dBm, the duration of the timer in the LTE random access process is not processed, or the duration of the timer in the LTE random access process is appropriately shortened.
And step 240, the terminal reinitiates the LTE random access according to the duration of the reset timer.
The terminal re-initiates LTE random access according to the duration of the reset timer, and specifically, when the terminal is in a strong signal environment, the terminal sends a random access request signaling to the base station, the base station sends a random access signaling to the terminal after configuring a signaling bearer SRB1 for the terminal, the terminal receives the random access signaling within the duration of the extended timer and completes SRB1 bearer and radio resource configuration with the base station, and then feeds back a random access completion signaling to the base station to complete LTE random access.
When the terminal is in a weak signal environment, the terminal sends a random access request signaling to the base station, the base station sends a random access signaling to the terminal after configuring a signaling bearer SRB1 to the terminal, the terminal receives the random access signaling within the duration of an unprocessed or shortened timer and completes SRB1 bearer and radio resource configuration with the base station, and then the random access completion signaling is fed back to the base station to complete LTE random access.
In this embodiment, after the first LTE random access fails, the terminal resets the duration of the timer in the LTE random access process by detecting the network status of the LTE network to be currently accessed and if the network status of the LTE network meets the preset network environment. Because the LTE random access failure can be determined not to be caused by weak signals but caused by delay of the base station reply only under the condition that the preset network environment is strong signals, the time length of a timer in the LTE random access process is prolonged, so that enough time is provided for the base station reply, and the success rate of the LTE random access in the strong signal environment is improved.
In one embodiment, the timer is a T300 timer, and the duration of the T300 timer may be selected from the following data, for example: 100ms, 200ms, 300ms, 400ms, 600ms, 1000ms, 1500ms, 2000 ms.
Please refer to fig. 3, which is a flow chart of LTE random access signaling. The T300 timer is started after the terminal sends a random access request signaling RRCConnectionRequest to the base station. The terminal receives a random access signaling RRCConnectionSetup sent by the base station in the duration of the T300 timer, wherein the RRCConnectionSetup signaling contains information required for establishing SRB1 signaling bearer and radio resource configuration. After the terminal completes the SRB1 bearer and radio resource configuration with the base station according to the RRCConnectionSetup signaling message, the terminal sends a random access completion signaling RRCConnectComplete signaling to the base station, and the terminal establishes a connection with the base station and then accesses the LTE network. The RRCConnectComplete signaling includes an attach request AttachRequest, a PDN (Public Data NetWorks) connectivity request, that is, a PDN connection request message.
The T300 timer represents a timer for controlling an RRC connection establishment (RRC connection establishment) procedure at a UE (User Equipment) side. Starting after the UE sends RRCConnectionRequest signaling to the base station.
Before the T300 timer times out if: 1, UE receives random access signaling-RRCConnectionSetup or random access rejection signaling-RRCConnectionReject; 2. triggering a Cell reselection-Cell-reselection process; and 3, terminating the RRC connection establishment process by a Non-Access Stratum (NAS) layer, and stopping the timer. If the timer is overtime, the UE resets a Media Access Control (MAC) layer, releases MAC layer configuration, resets all RLC (Radio Link Control, Radio Link layer Control) entities that have established rbs (Radio bearers), and notifies the NAS layer that RRC connection establishment fails.
The influence of the T300 timer on the network quality is generally to increase the duration of the T300 timer, which can improve the success rate of random access in the RRC connection establishment process of the terminal. However, when the channel quality of the cell selected by the terminal is poor or the load is large, the number of meaningless random access attempts of the terminal may be increased.
Reducing the duration of the T300 timer may reduce the number of unnecessary random access attempts by the UE when the channel quality of the cell selected by the UE is poor or the load is large. However, the success rate of random access during RRC connection setup of the UE may be reduced. The duration of the T300 timer is recommended to be 1000 ms.
As shown in fig. 4, the terminal establishes a connection with the base station through the LTE random access process to access the LTE network, if the access fails, the terminal determines a network status of the LTE network to be currently accessed, and if the network status of the LTE network meets a preset network environment, the terminal resets a duration of a timer in the LTE random access process, including:
in step 232, the terminal sends a random access request signaling to the base station, so that the base station receives the random access request signaling and configures a signaling bearer SRB1 to the terminal according to the random access request signaling.
The terminal sends a random access request signaling RRCConnectionRequest to the base station, the base station receives the RRCConnectionRequest, and the terminal is configured with a signaling bearer SRB 1. Specifically, the network DCM (data communication Module) configures the signaling bearer SRB1 for the USM. In LTE, SRB (signaling radio bearers) is a special radio bearer, which is only used for transmitting RRC and NAS messages, and in protocol 36.331, the transmission channels of SRBs are defined: SRB0 is used to transport RRC messages, which are transmitted on the logical channel CCCH; the SRB1 is used to transport RRC messages (perhaps including piggybacked NAS messages) and has a higher priority than the SRB2 before the establishment of the SRB2 bearer. Transmitting on a logical channel DCCH; SRB2 is used to transport NAS messages, has lower priority than SRB1, and always configures SRB2 for transport on logical channel DCCH after security mode activation.
In step 234, the terminal does not receive the random access signaling sent by the base station to the terminal after the SRB1 configuration is successful within the duration of the T300 timer, and the access fails.
The terminal sends RRCConnectionrequest signaling to the base station, the base station starts to configure SRB1 after receiving the RRCConnectionrequest signaling, and sends RRC ConnectionSetup signaling to the terminal after successful configuration. The T300 timer is started after the terminal sends RRCConnectionRequest signaling to the base station, the T300 timer times the time length of RRCConnectionSetup signaling received by the terminal, and if the RRCConnectionSetup signaling is not received in the time length of the T300 timer, the terminal fails to access the LTE network.
In step 236, the terminal determines the network status of the LTE network to be currently accessed, and if the network status of the LTE network meets a preset network environment, the terminal extends the duration of the T300 timer.
When the terminal fails to access the LTE network, the terminal judges the network condition of the LTE network to be accessed currently. If the determination result is that the network status of the LTE network is in a strong signal environment, it indicates that the terminal does not receive the RRCConnectionSetup signaling, which is not caused by a bad signal, but is caused by a delay in the base station reply, so that the duration of the T300 timer is extended.
For example, the terminal determines that the current Signal is a full Signal or LTE RSRP (Reference Signal receiving power) > -96dBm is a strong Signal, and Signal _ state is set to true to represent the strong Signal, although other values may be set to distinguish the strong Signal. The timer control module acquires the time length of the T300 timer and the value of sig _ state, if sig _ state is true and T300 is less than 200ms, the time length of the T300 timer is updated, the time length of the T300 timer can be set to 300ms, 400ms and 600ms, the time length of the T300 timer can also be set to more than 1000ms, and the preferred time length can be 1500ms or 2000 ms.
In this embodiment, after the first LTE random access failure, when it is detected that the network condition of the LTE network is in a strong signal environment, the duration of a specific T300 timer in the LTE random access process is extended, and the time for the base station to receive the RRCConnectionRequest signaling and to configure the SRB1 to successfully send the RRCConnectionSetup signaling to the terminal is extended. Because only under the condition of strong signals, it is indicated that the terminal does not receive the RRCConnectionSetup signaling is not caused by poor signals, but is caused by delay in the base station reply, the time length of the T300 timer is prolonged, and the time length of the T300 timer is prolonged to more than 1000ms, so that sufficient time is provided for the base station reply, and the success rate of LTE random access in a strong signal environment is improved.
In one embodiment, as shown in fig. 5, the terminal re-initiates LTE random access according to the extended duration of the timer, including:
step 242, the terminal resends the random access request signaling to the base station, so that the base station receives the random access request signaling and configures a signaling bearer SRB1 to the terminal according to the random access request signaling;
the terminal resends the random access request signaling RRCConnectionRequest signaling to the base station, and the base station receives the RRCConnectionRequest signaling and configures a signaling bearer SRB1 for the terminal. Specifically, the network DCM (data communication Module) configures a signaling bearer SRB1 for the USM (Universal Storage Module).
if the time length of the T300 timer after the prolonging is 1500ms, timing is started after the RRCConnectionRequest signaling is sent to the base station from the terminal, and if the terminal receives the random access signaling RRCConnectionSetup sent by the base station within 1500 ms.
The terminal carries out SRB1 bearing and wireless resource configuration with the base station according to the received RRCConnectionSetup signaling, and after the configuration is completed, the terminal sends a random access completion signaling-RRCConnectComplete signaling to the base station. So far, the terminal accesses the LTE network.
In this embodiment, after the first LTE random access fails, when determining whether the network status of the LTE network to be accessed currently is in a strong signal environment, if so, the T300 timer is extended, and the LTE random access is initiated again. The duration of the T300 timer is prolonged, so that enough time is provided for the base station to reply, and the success rate of LTE random access in a strong signal environment is improved. The random access failure caused by the fact that the time length of the T300 timer is not prolonged when the terminal initiates the LTE random access again is avoided.
In one embodiment, please refer to fig. 6, after the terminal re-sends the random access request signaling to the base station, so that the base station receives the random access request signaling and configures a signaling bearer SRB1 for the terminal according to the random access request signaling, the method includes:
In this embodiment, if the terminal does not receive the random access signaling sent after the base station SRB1 is successfully configured within the duration of the extended T300 timer, the terminal may determine again whether the network status of the LTE network to be currently accessed is in a strong signal environment, if so, extend the T300 timer, and initiate the LTE random access again. And if the judgment result is that the terminal is in the weak signal environment, the T300 timer does not need to be prolonged, and the LTE random access does not need to be restarted again. The longest time of the prolonged T300 timer cannot exceed 2000ms, so that the waiting time of a user is avoided from being too long.
In one embodiment, the extended T300 timer is less than 2000ms in duration.
