Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
The first embodiment,
An embodiment of the present invention provides a connection management method, which is applied to a terminal device, and as shown in fig. 1, the method includes:
step 101: determining the position of a paging subframe in a paging frame aiming at the terminal equipment based on idle state period parameters and identification information of the terminal equipment; the position of the paging subframe of the terminal equipment is at least partially different from the positions of the paging subframes corresponding to at least one other terminal equipment;
step 102: monitoring a Physical Downlink Control Channel (PDCCH) based on the position of a paging subframe in the paging frame when the fourth generation mobile communication technology 4G in a double-connection state is in an idle state; the dual connection state represents a state that the terminal equipment can be simultaneously connected with a 4G base station and a base station of a fifth generation mobile communication technology 5G;
step 103: and determining whether to switch from a 4G idle state of a dual connection state to a 4G connection state of the dual connection state based on a monitoring result of monitoring the PDCCH.
Here, the terminal device may be a User Equipment (UE) capable of accessing to a mobile communication system.
The present embodiment is mainly applied to a 4G mode and a 5G mode when a dual-connection terminal is in a connected state, where a special discontinuous reception method is adopted in the 4G mode, and it should be understood that the present embodiment performs the processing of the above procedure on the basis of considering both the real-time performance under 4G and the power saving performance of the terminal. The above-described flow is explained in detail below.
The Paging Frame (PF) may be considered as a radio Frame containing one or more POs; if DRX is used, the User Equipment (UE) monitors only the PO per DRX cycle. The PDCCH is scrambled when the paging occasion comes in order to resolve the above data.
Specifically, when the terminal enters the 4G and 5G dual connectivity state, the user plane information of the terminal is carried by the 5G, and the control plane information is carried by the 4G. The operation mode of the terminal in 4G is as follows.
The method further comprises the following steps: and acquiring the idle state period parameter, the system frame number SFN and the number of paging subframes which can be contained in the paging frame.
That is, the present embodiment includes the following preconditions:
precondition 1, the terminal agrees with the network to determine a Dual-connection 4G idle state period parameter Dual-DRX-Cycle, which is expressed by the number of wireless frames.
Parameter negotiation can be implemented in two ways:
mode 1. the terminal establishes or reconfigures RRC connection with the network, and then doubly connects 4G idle state Cycle parameters Dual-DRX-Cycle;
mode 2. the network device broadcasts the parameter Dual-DRX-Cycle in the broadcast information.
Precondition 2, the network side sends the definition of the number of paging subframes that can be contained in the paging frame to the terminal equipment through the wireless frame; PO-NUM may be used to indicate the number of POs in a radio frame.
In combination with the parameters of the devices in the foregoing several conditions, the manner for specifically calculating the location of the paging subframe may include determining, based on the idle-state period parameter and the identification information of the terminal device, the location of the paging subframe in the paging frame for the terminal device, including:
setting the SFN to a paging frame;
calculating identification information of the terminal equipment by adopting a hash function to obtain a first parameter aiming at the terminal equipment;
calculating to obtain a second parameter based on the first parameter and the idle state period parameter;
and calculating the position of the paging subframe in the paging frame based on the second parameter and the preset number of the paging moments.
Calculating identification information of the terminal equipment by adopting a hash function to obtain a first parameter aiming at the terminal equipment; the following formula can be used: UEHASH ═ hash function (UE _ IMSI). That is, the identification information of the terminal device may be the IMSI, and of course, may also be other identification information capable of uniquely identifying the terminal device, which is just an example. UEHUSH denotes the first parameter. The hash function may be a mature MD5, SHA1, or the like.
Based on the first parameter and the idle state period parameter, a second parameter is calculated, which may be represented as: temp. UEHASH mod (Dual-DRX-Cycle PO-NUM). The specific description is as follows: and multiplying the idle state period parameter by the number of paging subframes, performing modulo calculation by adopting a result obtained by multiplying the first parameter by the number of paging subframes, and taking the obtained result as a second parameter. Where TEMP represents the second parameter.
PF＝SFN。
The calculating the position of the paging subframe in the paging frame based on the second parameter and the preset number of the paging subframes further comprises:
performing modulus calculation by adopting SFN and idle state period parameters to obtain a first result;
dividing the second parameter by the number of preset paging moments to obtain a second result, and performing rounding-down calculation on the second result to obtain a second result after rounding calculation;
and when the first result is the same as the second result after the rounding calculation, performing modulo calculation based on the second parameter and the preset paging time number to obtain the position of the paging subframe in the paging frame.
The above calculation can be described using the following formula: when SFN mod Dual-DRX-Cycle is rounded down (TEMP/PO-NUM), PO is TEMP mod PO-NUM.
Further, the determining whether to switch from a 4G idle state of a dual connectivity state to a 4G connected state of the dual connectivity state based on a monitoring result of monitoring the PDCCH includes:
monitoring the PDCCH in a downlink subframe behind a paging subframe when monitoring the monitoring result of the PDCCH, representing the position of the paging subframe in the paging frame and receiving the PDCCH scrambled by a preset scrambling code corresponding to the terminal equipment;
when a PDCCH is monitored in a downlink subframe after the paging subframe, determining to switch from a 4G idle state of a dual-connection state to a 4G connection state of the dual-connection state;
in addition, when the PDCCH is not monitored in a downlink subframe after the paging subframe, a 4G idle state for maintaining the dual connectivity state is determined.
Specifically, the processing method provided in this embodiment can be described by adopting the following flow:
step 1: the terminal enters a dual connectivity 4G idle state. In this state, the terminal monitors the PDCCH on the subframe corresponding to PO in the radio frame indicated by the PF, and the CRC of the PDCCH is scrambled by a predetermined value Dual-RNTI.
Step 2, after receiving the PDCCH scrambled by the Dual-RNTI, the terminal monitors the PDCCH in the next downlink subframe; if the PDDCH (scrambled by the C-RNTI of the terminal) sent to the terminal by the base station is received in the downlink subframe, the terminal recovers the 4G connection state, otherwise, the terminal returns to the dual-connection 4G idle state.
One specific example is as follows:
precondition 1-network broadcast Dual-connection 4G idle state period parameter Dual-DRX-Cycle, which is expressed by the number of radio frames and takes 64 values, namely 64 radio frames, 640 ms. The value of the preset value Dual-RNTI is 0 xFFFC.
Precondition 2-4 subframes of 1, 3, 6, 8, etc. are defined as PO in the radio frame, i.e. PO-NUM is 4.
Step 1: the terminal enters a dual connectivity 4G idle state. In this state, the terminal monitors the PDCCH on the subframe corresponding to PO in the radio frame indicated by the PF, and the CRC of the PDCCH is scrambled by a predetermined value Dual-RNTI. Wherein PF and PO are calculated as follows:
UEHASH＝SHA1(UE_IMSI)
TEMP＝UEHASH mod(Dual-DRX-Cycle*PO-NUM)
PF＝SFN；
when SFN mod Dual-DRX-Cycle is rounded down (TEMP/PO-NUM), PO is TEMP mod PO-NUM.
Step 2, after receiving the PDCCH scrambled by the Dual-RNTI, the terminal monitors the PDCCH in the next downlink subframe; if the PDDCH (scrambled by the C-RNTI of the terminal) sent to the terminal by the base station is received in the downlink subframe, the terminal recovers the 4G connection state, otherwise, the terminal returns to the dual-connection 4G idle state.
By adopting the scheme, the mode of calculating the position of the paging subframe in the paging frame of the terminal equipment is associated with the identification information of the terminal equipment, and the PDCCH monitoring is carried out at the calculated paging subframe; therefore, different terminal devices can be in different paging subframes to transmit and receive the PDCCH, so that the problem of collision at the transmission moment of the PDCCH is reduced, and load balance is realized; in addition, the above scheme reduces the problem of collision at the sending time of the PDCCH, and simultaneously still considers that the terminal works in a non-connection receiving state under 4G, thereby meeting the requirements of power saving and response time delay.

step 201: determining the position of a paging subframe in a paging frame aiming at each terminal device based on idle state period parameters and identification information of each terminal device of at least one terminal device managed by the terminal device; the positions of paging subframes corresponding to different terminal devices in the at least one terminal device are at least partially different;
step 202: when a first terminal device in a 4G idle state of a fourth generation mobile communication technology in a dual connectivity state exists in at least one terminal device managed by the first terminal device, acquiring the position of a paging subframe in a paging frame for the first terminal device;
step 203: transmitting a Physical Downlink Control Channel (PDCCH) to the first terminal equipment based on the position of a paging subframe in a paging frame for the first terminal equipment; wherein the PDCCH can control at least the first terminal device to switch from a 4G idle state of a dual-connection state to a 4G connection state of the dual-connection state.
Here, the terminal device may be a User Equipment (UE) capable of accessing to a mobile communication system. The network device may be a network device in a mobile communication network such as a base station, and certainly may have other entity forms, which is not exhaustive in this embodiment.
The present embodiment is mainly applied to a 4G mode and a 5G mode when a dual-connection terminal is in a connected state, where a special discontinuous reception method is adopted in the 4G mode, and it should be understood that the present embodiment performs the processing of the above procedure on the basis of considering both the real-time performance under 4G and the power saving performance of the terminal. The above-described flow is explained in detail below.
The Paging Frame (PF) may be considered as a radio Frame containing one or more POs; if DRX is used, the User Equipment (UE) monitors only the PO per DRX cycle. The PDCCH is scrambled when the paging occasion comes in order to resolve the above data.
Specifically, when the terminal enters the 4G and 5G dual connectivity state, the user plane information of the terminal is carried by the 5G, and the control plane information is carried by the 4G. The operation mode of the terminal in 4G is as follows.
The method further comprises the following steps: and acquiring the idle state period parameter, the system frame number SFN and the number of paging subframes which can be contained in the paging frame.
That is, the present embodiment includes the following preconditions:
precondition 1, the terminal agrees with the network to determine a Dual-connection 4G idle state period parameter Dual-DRX-Cycle, which is expressed by the number of wireless frames.
Parameter negotiation can be implemented in two ways:
mode 1. the terminal establishes or reconfigures RRC connection with the network, and then doubly connects 4G idle state Cycle parameters Dual-DRX-Cycle;
mode 2. the network device broadcasts the parameter Dual-DRX-Cycle in the broadcast information.
Precondition 2, the network side sends the definition of the number of paging subframes that can be contained in the paging frame to the terminal equipment through the wireless frame; PO-NUM may be used to indicate the number of POs in a radio frame.
Combining the parameters of the devices in the aforementioned several conditions, the manner for specifically calculating the location of the paging subframe may include:
setting the SFN to a paging frame;
calculating the identification information of each terminal device by adopting a hash function to obtain a first parameter aiming at each terminal device;
calculating to obtain a second parameter based on the first parameter and the idle state period parameter;
and calculating the position of the paging subframe in the paging frame of each terminal device based on the second parameter and the preset number of the paging subframes.
Calculating identification information of the terminal equipment by adopting a hash function to obtain a first parameter aiming at the terminal equipment; the following formula can be used: UEHASH ═ hash function (UE _ IMSI). That is, the identification information of the terminal device may be the IMSI, and of course, may also be other identification information capable of uniquely identifying the terminal device, which is just an example. UEHUSH denotes the first parameter. The hash function may be a mature MD5, SHA1, or the like.
Based on the first parameter and the idle state period parameter, a second parameter is calculated, which may be represented as: temp. UEHASH mod (Dual-DRX-Cycle PO-NUM). The specific description is as follows: and multiplying the idle state period parameter by the number of paging subframes, performing modulo calculation by adopting a result obtained by multiplying the first parameter by the number of paging subframes, and taking the obtained result as a second parameter. Where TEMP represents the second parameter.
PF＝SFN。
The calculating the position of the paging subframe in the paging frame based on the second parameter and the preset number of the paging subframes further comprises:
performing modulus calculation by adopting SFN and idle state period parameters to obtain a first result;
dividing the second parameter by the number of preset paging moments to obtain a second result, and performing rounding-down calculation on the second result to obtain a second result after rounding calculation;
and when the first result is the same as the second result after the rounding calculation, performing modulo calculation based on the second parameter and the preset paging time number to obtain the position of the paging subframe in the paging frame of each terminal device.
The above calculation can be described using the following formula: when SFNmod Dual-DRX-Cycle is rounded down (TEMP/PO-NUM), PO is TEMP mod PO-NUM.
Further, the determining whether to switch from a 4G idle state of a dual connectivity state to a 4G connected state of the dual connectivity state based on a monitoring result of monitoring the PDCCH includes:
monitoring the PDCCH in a downlink subframe behind a paging subframe when monitoring the monitoring result of the PDCCH, representing the position of the paging subframe in the paging frame and receiving the PDCCH scrambled by a preset scrambling code corresponding to the terminal equipment;
when a PDCCH is monitored in a downlink subframe after the paging subframe, determining to switch from a 4G idle state of a dual-connection state to a 4G connection state of the dual-connection state;
in addition, when the PDCCH is not monitored in a downlink subframe after the paging subframe, a 4G idle state for maintaining the dual connectivity state is determined.
Specifically, the processing method provided in this embodiment can be described by adopting the following flow:
step 1: the terminal enters a dual connectivity 4G idle state. In this state, the terminal monitors the PDCCH on the subframe corresponding to PO in the radio frame indicated by the PF, and the CRC of the PDCCH is scrambled by a predetermined value Dual-RNTI.
Step 2, after receiving the PDCCH scrambled by the Dual-RNTI, the terminal monitors the PDCCH in the next downlink subframe; if the PDDCH (scrambled by the C-RNTI of the terminal) sent to the terminal by the base station is received in the downlink subframe, the terminal recovers the 4G connection state, otherwise, the terminal returns to the dual-connection 4G idle state.
One specific example is as follows:
precondition 1-network broadcast Dual-connection 4G idle state period parameter Dual-DRX-Cycle, which is expressed by the number of radio frames and takes 64 values, namely 64 radio frames, 640 ms. The value of the preset value Dual-RNTI is 0 xFFFC.
Precondition 2-4 subframes of 1, 3, 6, 8, etc. are defined as PO in the radio frame, i.e. PO-NUM is 4.
Step 1: the terminal enters a dual connectivity 4G idle state. In this state, the terminal monitors the PDCCH on the subframe corresponding to PO in the radio frame indicated by the PF, and the CRC of the PDCCH is scrambled by a predetermined value Dual-RNTI. Wherein PF and PO are calculated as follows:
UEHASH＝SHA1(UE_IMSI)
TEMP＝UEHASH mod(Dual-DRX-Cycle*PO-NUM)
PF＝SFN；
when SFN mod Dual-DRX-Cycle is rounded down (TEMP/PO-NUM), PO is TEMP mod PO-NUM.
Step 2, after receiving the PDCCH scrambled by the Dual-RNTI, the terminal monitors the PDCCH in the next downlink subframe; if the PDDCH (scrambled by the C-RNTI of the terminal) sent to the terminal by the base station is received in the downlink subframe, the terminal recovers the 4G connection state, otherwise, the terminal returns to the dual-connection 4G idle state.
By adopting the scheme, the mode of calculating the position of the paging subframe in the paging frame of the terminal equipment is associated with the identification information of the terminal equipment, and the PDCCH monitoring is carried out at the calculated paging subframe; therefore, different terminal devices can be in different paging subframes to transmit and receive the PDCCH, so that the problem of collision at the transmission moment of the PDCCH is reduced, and load balance is realized; in addition, the above scheme reduces the problem of collision at the sending time of the PDCCH, and simultaneously still considers that the terminal works in a non-connection receiving state under 4G, thereby meeting the requirements of power saving and response time delay.
