Description

Method, device and terminal for transmitting pilot signal strength measurement message

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a terminal for transmitting a pilot signal strength measurement message.

Background technique

When cell reselection or handover is required, the terminal needs to perform pilot signal strength measurement on the signal quality of the neighboring cell, and reports the pilot signal strength measurement message to the network side. For example, in a cell segment where the network signal is poor or the network signal has interference, the terminal continuously monitors the signal of the current serving cell or the neighboring cell during a Code Division Multiple Access (CDMA) call, and The signal of the current serving cell is reported to the network side. After receiving the pilot signal strength measurement message reported by the terminal, the network side indicates whether the terminal needs to perform handover according to the pilot signal strength measurement result.

At present, after the terminal sends the pilot signal strength measurement message to the network side, the network side needs to reply the response message. If the network side does not reply the response information, the terminal needs to retransmit the original pilot signal strength measurement message until the network side replies. Answer the message or exceed the maximum number of retransmissions.

In the network environment where the network signal changes frequently or the network signal is not good, if the network side does not receive the pilot signal strength measurement message, or the network side receives the pilot signal strength, the method uses the above-mentioned pilot signal strength measurement message retransmission. The measurement message but the sent response message is not received by the terminal side, which causes the retransmission of a large number of pilot signal strength measurement messages on the terminal side and the network side to send a large amount of response information, which increases the signaling interaction between the terminal and the network side. The load on the terminal and network side is large.

Summary of the invention

The embodiment of the invention provides a method, a device and a terminal for transmitting a pilot signal strength measurement message, so as to reduce signaling interaction between the terminal and the network side, and reduce the load on the terminal and the network side.

In a first aspect, a method for transmitting a pilot signal strength measurement message is provided, in which a second guide is sent The first pilot signal strength measurement message is detected in the retransmission queue of the pilot signal strength measurement message before the frequency signal strength measurement message, and if present, the first pilot signal strength in the retransmission queue of the pilot signal strength measurement message is deleted. The measurement message is sent and the second pilot signal strength measurement message is sent to prevent the terminal and the network side from transmitting the repeated pilot signal strength measurement message, so as to reduce signaling interaction between the terminal and the network side, and reduce the load on the terminal and the network side.

The first pilot signal strength measurement message and the second pilot signal strength measurement message are pilot signal strength measurement results of different types of time and the measurement time of the second pilot signal strength measurement message. The second pilot signal strength measurement message is the latest pilot signal strength measurement result, which is later than the measurement moment of the first pilot signal strength measurement message.

In a possible design, in the case that it is determined that the second pilot signal strength measurement message needs to be sent, the step of detecting whether there is a first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue is performed. The step of performing detection without the need to transmit pilot signal strength measurement information is avoided, and signaling overhead is reduced.

In another possible design, if the terminal deletes the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue, the terminal receives the strength of the first pilot signal sent by the network side. The response information of the message is measured, and the response information is ignored to reduce the message processing flow.

In another possible design, after the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue is deleted, retransmission of the first pilot signal strength measurement message may be cancelled. The timer is used to prevent abnormal call drop after the number of times the retransmission timer expires reaches the maximum number of retransmissions.

In another possible design, after determining that the number of retransmissions of the first pilot signal strength measurement message reaches a retransmission threshold, the first pilot in the pilot signal strength measurement message retransmission queue is retransmitted. The signal strength measurement message is deleted to reduce the processing load of the terminal, and the original pilot signal strength measurement message retransmission mechanism can be retained to some extent.

The threshold of the retransmission times may be an average value of the number of times of retransmission of each pilot signal strength measurement message in the T time.

In a possible design, the apparatus for transmitting a pilot signal strength measurement message includes a processing unit and a sending unit, and the processing unit is configured to detect whether a first pilot signal strength measurement message exists in a pilot signal strength measurement message retransmission queue. And detecting, in the case that the first pilot signal strength measurement message exists in the pilot signal strength measurement message retransmission queue, the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue delete. The sending unit is configured to send the second pilot signal strength measurement message.

In another possible design, the processing unit of the means for transmitting the pilot signal strength measurement message may be a processor and the transmitting unit may be a transmitter.

When the processing unit of the apparatus transmitting the pilot signal strength measurement message is a processor and the transmitting unit is a transmitter, the means for transmitting the pilot signal strength measurement message may be a terminal, the terminal including a processor and a transmitter. The processor is configured to support a method in which the terminal performs the transmitting pilot signal strength measurement message related to the first aspect above.

detailed description

The technical solutions in the embodiments of the present invention are described in detail below with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are a part of the embodiments of the present invention, and not all of the embodiments.

As shown in Figure 1, the terminal accesses the core network (Core Network, CN) through the Radio Access Network (RAN), and performs voice services and supplementary services such as number display, call forwarding, call waiting, and conference. Phone and more.

It should be noted that the terminal may include various handheld devices with wireless communication functions, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to the wireless modem, and various forms of user equipment (User Equipment, UE), mobile station (MS), terminal equipment (Terminal Equipment), and the like.

The technology described in the embodiment of the present invention can be applied to a second generation 2G network, and can also be applied to the first Third-generation 3G network and Long Term Evolution (LTE) systems, or other wireless communication systems using various radio access technologies, such as code division multiple access, frequency division multiple access, time division multiple access, orthogonal frequency division A system of multiple access, single carrier frequency division multiple access and other access technologies. In addition, it can also be applied to the subsequent evolution system using the LTE system, such as the fifth generation 5G system and the like.

The communication method according to the embodiment of the present invention mainly describes a process of transmitting pilot signal strength and transmitting a pilot signal strength measurement message by a terminal. For example, when the terminal needs to perform cell reselection or handover when the network signal is poor or the network signal has interference, the terminal needs to perform pilot signal strength measurement and transmission of the pilot signal strength measurement message.

Currently, the process by which a terminal performs pilot signal strength measurement can occur during a CDMA call. The 3rd Generation Partnership Project 2 (3GPP2) standardizes the processing flow of pilot signal strength measurement during CDMA calls through the C.S0005 protocol.

FIG. 2 is a schematic diagram showing a process of retransmission of a pilot signal strength measurement message during a CDMA call. When the terminal moves at the edge of the cell or the cell signal changes frequently, if the cell signal strength satisfies the condition of joining the active set or exiting the active set, the terminal initiates a pilot signal strength measurement process and generates a pilot signal strength measurement message 1. When the terminal sends the generated pilot signal strength measurement message 1 to the network side, the CDMA protocol layer 3 of the terminal sends a notification message for indicating the transmission of the pilot signal strength measurement message 1 to the CDMA protocol layer 2, and the CDMA protocol layer 2 receives the notification message. The pilot message sends the pilot signal strength measurement message 1 to the receiving and transmitting module (Receive Transport, RXTX), and the receiving and transmitting module sends the pilot signal strength measurement message 1 to the network side through the bottom layer. The CDMA protocol layer 2 adds the pilot signal strength measurement message 1 to the pilot signal strength measurement message retransmission queue and initiates a retransmission timer for the pilot signal strength measurement message 1. If the retransmission timer of the pilot signal strength measurement message 1 times out (eg, exceeds 400 milliseconds), the pilot signal strength measurement message 1 is retransmitted, and the retransmission timing for the pilot signal strength measurement message 1 is restarted. Device. The above steps are repeated until the response message (Ack) of the network side reply is received or the number of retransmissions exceeds the maximum number of retransmissions (for example, 13 times).

During the retransmission of the pilot signal strength measurement message 1, if the signal strength of the cell satisfies the above condition again, the terminal will again initiate pilot signal strength measurement and generate pilot signal strength measurement. Message 2, and transmit and retransmit the frequency signal strength measurement message 2 in the same manner as the transmit and re-transmitted frequency signal strength measurement message 1. FIG. 2 illustrates an example of a response message that the network side responds to the pilot signal strength measurement message 2 after receiving a timeout for the pilot signal strength measurement message 2 retransmission timer.

The pilot signal strength measurement message 1 and the pilot signal strength measurement message 2 are pilot signal strength measurement messages obtained by the terminal performing pilot measurement at different times, that is, the pilot signal strength measurement message 1 and the pilot signal strength measurement message 2 are Pilot signal strength measurement messages of the same type but at different times. In the embodiment of the present invention, to identify the pilot signal strength measurement message at different times, the terminal may set different sequence numbers for the pilot signal strength measurement message 1 and the pilot signal strength measurement message 2.

Generally, the network side performs an acknowledgment response on each pilot signal strength measurement message sent by the terminal, and the acknowledgment mechanism is to identify the pilot signal strength measurement message by identifying the sequence number of the pilot signal strength measurement message in the response message. The response, after receiving the response message of the pilot signal strength measurement message, the terminal deletes the pilot signal strength measurement message identified by the sequence number from the retransmission queue by using the sequence number included in the response message, and stops retransmission However, the pilot signal strength measurement message that has not received the response message needs to continue to be retransmitted.

Therefore, in a network environment where the network signal changes frequently or the network signal is not good, if the network side does not receive the pilot signal strength measurement message, or the network side receives the pilot signal strength measurement message, but the sent response message terminal does not receive On the one hand, the retransmission of a large number of pilot signal strength measurement messages on the terminal side and the transmission of a large amount of response information on the network side increase the signaling interaction between the terminal and the network side, and the load on the terminal and the network side is large. . On the other hand, if the number of retransmissions of the terminal re-transmitted frequency signal strength measurement message exceeds the maximum number of retransmissions, the terminal exits the call process according to the protocol, which will cause the call to be dropped.

An embodiment of the present invention provides a method for transmitting a pilot signal strength measurement message, and before detecting a pilot signal strength measurement message, detecting whether a pilot signal strength measurement message to be sent exists in a pilot signal strength measurement message retransmission queue The pilot signal strength measurement message of the same type and being sir, if present, deletes the pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue to prevent the terminal from repeatedly transmitting to the network side. Frequency signal strength measurement message to Reduce the signaling interaction between the terminal and the network side, and reduce the load on the terminal and the network side.

The following is a description of the convenience of the description. The pilot signal strength measurement message is referred to as a first pilot signal strength measurement message, and the newly generated pilot signal strength measurement message to be transmitted is referred to as a second pilot. a signal strength measurement message, the first pilot signal strength measurement message and the second pilot signal strength measurement message are pilot signal strength measurement messages of different types and times, and the second pilot signal strength measurement message The generation time is later than the generation time of the first pilot signal strength measurement message.

S101: The terminal detects whether there is a first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue.

If the first pilot signal strength measurement message exists in the pilot signal strength measurement message retransmission queue, then S102 is performed. If the first pilot signal strength measurement message does not exist in the pilot signal strength measurement message retransmission queue, S103 may be directly performed.

S102: The terminal deletes the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue, and then performs S103.

S103: The terminal sends a second pilot signal strength measurement message.

In the embodiment of the present invention, before transmitting the second pilot signal strength measurement message, detecting whether there is a first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue, and if present, deleting the first pilot signal After the strength measurement message is sent, the second pilot signal strength measurement message is sent to prevent the terminal from repeatedly transmitting the pilot signal strength measurement message to the network side, so as to reduce signaling interaction between the terminal and the network side, and reduce the load on the terminal and the network side.

Optionally, in the embodiment of the present invention, if it is determined that the second pilot signal strength measurement message needs to be sent, whether the first pilot signal strength measurement message exists in the retransmission queue for detecting the pilot signal strength measurement message is performed. In the step of avoiding the need to transmit the pilot signal strength measurement information, the detecting step of detecting whether the first pilot signal strength measurement message exists in the pilot signal strength measurement message retransmission queue in S101 is performed, and the signaling overhead is reduced.

In the embodiment of the present invention, after the terminal deletes the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue, the terminal receives the first pilot signal strength measurement message sent by the network side. In response to the message, the response message is ignored to reduce the message processing flow.

Embodiments of the Present Invention A method of transmitting a pilot signal strength measurement message according to the above embodiment will be described below in conjunction with practical applications.

The following describes the process of performing pilot signal strength measurement information retransmission in a CDMA call as an example, and performs the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue. Description. For other communication systems, the manner of transmitting the pilot signal strength measurement message between the terminal and the network side is similar, and details are not described herein again. For the case where the first pilot signal strength measurement message does not exist in the pilot signal strength measurement message retransmission queue, reference may be made to the flow of the existing pilot signal strength measurement message, and details are not described herein again.

FIG. 4 is a schematic flowchart of a method for transmitting a pilot signal strength measurement message during a CDMA call according to an embodiment of the present invention. As shown in Figure 4:

S201: The terminal performs the first pilot signal strength measurement, and generates and sends a first pilot signal strength measurement message.

In the embodiment of the present invention, the terminal sends the first pilot signal strength measurement message, and adds the first pilot signal strength measurement message to the pilot signal strength measurement message retransmission queue to start the first pilot signal strength. The execution process of the retransmission timer of the measurement message can be referred to the transmission and retransmission process of the pilot signal strength measurement message 1 in the flow shown in FIG. 2.

S202: The terminal performs the second pilot signal strength measurement, generates a second pilot signal strength measurement message, determines that the second pilot signal strength measurement message needs to be sent, and sends the CDMA protocol layer 3 of the terminal to the CDMA protocol layer 2 for indication. A notification message for transmitting a second pilot signal strength measurement message.

S203: The terminal detects that there is a first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue, and the CDMA protocol layer 2 measures the first pilot signal strength in the pilot signal strength measurement message retransmission queue. The message was deleted.

Optionally, in the embodiment of the present invention, after the CDMA protocol layer 2 deletes the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue, the first pilot may be retransmitted. The retransmission timer of the signal strength measurement message prevents the abnormal call drop after the retransmission timer timeout reaches the maximum number of retransmissions.

S204: The RXTX module of the terminal sends a second pilot signal strength measurement message. The CDMA protocol layer 2 adds a second pilot signal strength measurement message to the pilot signal strength measurement message retransmission queue to initiate a retransmission timer for the second pilot signal strength measurement message.

S205: After the retransmission timer of the second pilot signal strength measurement message expires, the terminal CDMA protocol layer 2 retransmits the second pilot signal strength measurement message, and restarts the weighting of the second pilot signal strength measurement message. Pass the timer.

S206: The RXTX module of the terminal receives the response information of the first pilot signal strength measurement message on the network side, and the RXTX module sends the response information of the first pilot signal strength measurement message to the CDMA protocol layer 2 of the terminal, and the CDMA of the terminal Protocol layer 2 ignores the response information for the first pilot signal strength measurement message.

S207: The RXTX module of the terminal receives the response information of the second pilot signal strength measurement message on the network side, and the RXTX module sends the response information of the second pilot signal strength measurement message to the CDMA protocol layer 2 of the terminal, and the terminal CDMA The protocol layer 2 transmits the response information for the second pilot signal strength measurement message to the CDMA protocol layer 3 of the terminal, and deletes the second pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue and A retransmission timer of the second pilot signal strength measurement message.

In the embodiment of the present invention, when it is determined that the second pilot signal strength measurement message needs to be sent, the first pilot signal strength measurement message is detected in the pilot signal strength measurement message retransmission queue, and if present, the pilot signal is deleted. After the first pilot signal strength measurement message in the strength measurement message retransmission queue is sent, the second pilot signal strength measurement message is sent, which can prevent the terminal from repeatedly transmitting the pilot signal strength measurement message to the network side, so as to reduce the terminal and the network side. Inter-signaling interaction reduces the load on the terminal and network side. After the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue is deleted, if the response information sent by the network side for the first pilot signal strength measurement message is received, the message is ignored. The first pilot signal strength measures response information of the message to reduce the message processing flow.

Further, after the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue is deleted, or after receiving the response message of the second pilot signal strength measurement message, the retransmission may be cancelled. The retransmission timer of the first pilot signal strength measurement message is used to avoid abnormal call drop after the retransmission timer timeout number reaches the maximum number of retransmissions.

Optionally, in the embodiment of the present invention, to reduce the signaling interaction between the terminal and the network side, the second pilot signal strength measurement message may be cancelled after receiving the response message of the first pilot signal strength measurement message. A response message to the second pilot signal strength measurement message is sent and ignored.

Optionally, after the number of retransmissions of the first pilot signal strength measurement message reaches a set number of times, the terminal may receive a response message fed back by the network side, where the first pilot signal strength measurement message is retransmitted. The number of times is relatively small, and the process flow of the terminal is relatively simple and the load is relatively small, so that the first pilot signal strength can be determined in the embodiment of the present invention. After the number of retransmissions of the measurement message reaches the threshold of the number of retransmissions, the first pilot signal strength measurement message in the retransmission queue of the pilot signal strength measurement message is deleted, so as to reduce the processing load of the terminal, and to a certain extent The original pilot signal strength measurement message retransmission mechanism is retained.

The threshold of the retransmission times in the embodiment of the present invention may be an average value of the number of times of retransmission of each pilot signal strength measurement message in the T time. For example, if the pilot signal strength measurement is performed N times and the N pilot signal strength measurement messages are sent in the T time, the number of retransmission times of the N pilot signal strength measurement messages in the T time is determined, and N times are determined. The average value of the pilot signal strength measurement message is used as the threshold of the number of retransmissions. The size of the T may be determined according to the signal receiving power of the terminal and the signal transmitting power. Generally, when the signal receiving power is weak or the signal transmitting power is strong, the T set is greater than the signal receiving power or the signal transmitting power is weak. T. For example, in the case where the signal receiving power is less than -100 dbm or the signal transmitting power is greater than 10 dbm, T can be set to 10 s. In the case where the signal receiving power is greater than -90 dbm or the signal transmitting power is less than 10 dbm, T can be set to 5 s. In the embodiment of the present invention, N is a positive integer, and T is not less than 0.

If the retransmission threshold is not reached, S304 is performed, and if the retransmission threshold is reached, S306 is performed. .

S304: After the retransmission timer of the first pilot signal strength measurement message expires, the terminal CDMA protocol layer 2 retransmits the first pilot signal strength measurement message, and restarts the first pilot signal strength measurement message. Retransmission timer.

The above steps are repeatedly performed until the number of retransmissions of the first pilot signal strength measurement message reaches the retransmission number threshold, and S306 is performed.

If the number of retransmissions of the first pilot signal strength measurement message does not reach the retransmission threshold, the terminal RXTX module receives the response information of the network side for the first pilot signal strength measurement message, and then executes S305.

S305: The RXTX module sends response information for the first pilot signal strength measurement message to the CDMA protocol layer 2 of the terminal, and the CDMA protocol layer 2 of the terminal sends the response information for the first pilot signal strength measurement message to the CDMA of the terminal. Protocol layer 3, and deleting the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue and a retransmission timer for the first pilot signal strength measurement message.

S306: The CDMA protocol layer 2 of the terminal deletes the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue, and cancels retransmission retransmission timing of the first pilot signal strength measurement message. Device.

The execution steps of S307, S308, S309, and S310 are the same as the execution steps of S204, S205, S206, and S207, and are not described herein again.

In the embodiment of the present invention, before deleting the first pilot signal strength measurement message in the pilot signal strength measurement message retransmission queue, determining whether the number of retransmissions of the first pilot signal strength measurement message reaches a heavy weight If the retransmission threshold is not reached, the retransmission is performed according to the retransmission mechanism of the original first pilot signal strength measurement message, and if the retransmission threshold is reached, the pilot information is obtained. The first pilot signal strength measurement message in the retransmission queue of the strength measurement message is deleted, which can reduce the processing load of the terminal, and can retain the original pilot signal strength measurement message retransmission mechanism to a certain extent.

It should be noted that the reference numerals in the respective drawings of the embodiments of the present invention are only for illustrative purposes, and do not limit the order of execution of the steps. For example, in FIG. 4, the sequence of execution of S206 and S207 is not limited, S207 This can be performed before the step S206.
