Description

Method, system and access device for access terminal requesting to enter semi-connected state

The present invention relates to a semi-connection technology of a wireless communication system, and in particular, to a method, system, and access device for an access terminal to request an access network to enter a semi-connected state. Background of the invention

In the wireless communication technology, each access terminal (AT) and an access network (AN) jointly maintain the state of the wireless link. After the terminal device is powered on, the state of its wireless link is generally in one of three states: capturing a network state, an idle state, or a connection state. When in the connected state, the AN allocates dedicated Media Access Control (MAC) resources to the AT, that is, the AN can schedule the AT and allocate dedicated forward and reverse time-frequency resource blocks to the AT. However, when the AT is in the connected state, there are some non-continuous low-speed services that require resources of the forward link only periodically, aperiodically or non-fixedly, and are not sensitive to delay, such as watching stock market, Receiving an email notification, browsing a webpage, etc., for such a service, in order to save power consumption of the AT and release the reverse bandwidth, a wireless link in a semi-connected state appears. The semi-connected state is a special state attached to the connected state. In the semi-connected state, the MAC resources allocated by the AN to the AT in the connected state are still reserved, but the AT goes to the sleep state after listening to the forward control channel and continues for a period of time. In the sleep state, the AT does not transmit any reverse channel to the node. The power then wakes up to listen to the forward control channel when the next cycle arrives, while the AN only activates the AT and schedules packets to the AT when the AT wakes up to listen to the forward control channel. It can be seen that the use of the semi-connected state can save the power consumption of the AT and release the reverse bandwidth, especially for the above-mentioned resources that only need to be forward-period periodically or possibly aperiodic or non-fixed, and are not sensitive to delay. Non-continuous low-speed business. FIG. 1 is a schematic flow chart of a method for requesting an access terminal between an AT and an AN to enter a semi-connected state in the prior art. As shown in Figure 1, when the AT enters the semi-connected state, it sends a semi-connected request message (SemiConnectedRequest) to the AN, and carries the semi-connected time parameter transmitted to the AN, including: semi-connected period (SemiConnectedPeriod) parameter, semi-join Offset (SemiConnectedOffset) parameter and semi-connected wake-up duration (SemiConnectedWakeDuration) parameter. According to the provisions of the prior art, AT wakes up when the conditions of the three time parameters are met. The AN carries information in the semi-connected response message (SemiConnectedResponse) that accepts or rejects the AT's request to enter the semi-connected state. If the AN agrees to the AT's request, the AT enters the semi-connected state; if the AN rejects the AT's request, the AT remains in the connected state. The AN indicates whether it agrees with the AT request through the semi-connected status ( SemiConnectedStatus) field in the semi-connection reply message. Wherein, the field is set to 1 to agree to the AT request, and 0 is to indicate the request to reject the AT. Specifically, Table 1 shows the structure of a prior art semi-join request message, and Table 2 shows the structure of a prior art semi-join response message.

These three semi-connected time parameters. However, during the AT request to enter the semi-connected state, there are certain scenarios that do not require the AT to transmit these time parameters each time. For example: Scenario 1, the AT requests to enter the semi-connected state, but the AN does not agree that the AT transitions to the semi-connected state, and the AT initiates the request again soon; Scenario 2, the AT has entered the semi-connected state, but because the overhead message parameters are to be updated, Or the semi-connected state is ended because the forward packet is to be received or the reverse packet is to be sent, and then the request is again initiated to enter the semi-connected state. Similar to such a scenario, the AT will initiate a semi-connected state to the same AN again or even multiple times after the initial transmission request. However, most of the time, the values of these parameters will not change for the same AT. Therefore, carrying these parameters each time is superfluous and will result in waste of air interface resources.

In addition, in the prior art, multiple ATs in a semi-connected state may be camped under one AN. To ensure load balancing of traffic channels, the time at which these ATs wake up to monitor the control channel should be evenly distributed on the time axis. Therefore, when the AT initiates a semi-join request, the AN determines whether the semi-join time parameter of the AT request is the same or similar to other ATs. If the same or similar, the AN will determine that the time parameter of the AT request is unreasonable. , and simply reject the AT's semi-join request. After that, the AT will still blindly repeat the request with the rejected semi-join time parameter and be repeatedly rejected by the AN, thereby causing waste of air interface resources. In summary, the method for the prior art access terminal to request to enter the semi-connected state has the disadvantage of wasting air interface resources. Summary of the invention

In order to make the technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments.

Example 1

In the first embodiment, before sending the semi-connection request message, the AT determines whether the semi-connection time parameter needs to be sent to the access network; if yes, the AT carries the semi-connection time parameter to be sent in the semi-connection request message. Sending to the AN, otherwise, the AT sends a semi-connection request message that does not carry the semi-connection time parameter to the access network; the AN sends a semi-connection request message to the AT semi-connection request after receiving the semi-connection request message sent by the AT. Therefore, the AT carries the semi-join time parameter to be transmitted in the semi-connection request message only when it is determined that the semi-connection time parameter needs to be transmitted.

In a specific implementation of Embodiment 1 of the present invention, a first switch field-ParameterEnable field is added on the basis of the prior art semi-join request message structure (see Table 1). The structure of the semi-join request message to which the first switch field is added is as shown in Table 3 below.

table 3 The first switch field can be set to a different state. The first embodiment uses different states of the first switch field to indicate different situations in which the access terminal carries the semi-connection time parameter in the semi-connection request message.

Figure 2 is a basic flow chart of Embodiment 1 of the present invention. As shown in FIG. 2, the method for the access terminal of the first embodiment to enter the semi-connected state specifically includes the following steps:

Step 201: The access terminal determines whether a semi-connection time parameter needs to be sent to the access network; if yes, step 202 is performed; otherwise, step 204 is performed.

In a specific implementation of this step, the access terminal may determine, by using, but not limited to, whether a semi-connection time parameter needs to be sent to the access network:

(1) When the access terminal initially sends a semi-connection request message, it needs to send a semi-connection time parameter.

(2) When the access terminal has stored the time parameter of the access network permission when the last semi-connection request is made, it does not need to be sent. Specifically, for example, when the access terminal is in the scene 1 or scene 2 described in the background art, it is not necessary to transmit a time parameter. Step 202: The access terminal sets, according to the semi-connected time parameter to be sent, the first switch field to: indicating that the semi-connection time parameter field corresponding to the semi-connection time parameter to be sent set in the semi-connection request message is valid. And the semi-connection time parameter field corresponding to the other semi-connection time parameter that does not need to be sent is invalid, and then step 203 is performed; Step 203, the access terminal will only carry the semi-connection request message of the semi-connection time parameter to be sent. Send to the access network, and then go to step 206.

Step 204: The access terminal sets the first switch field to: a state indicating that all the semi-connection time parameter fields set in the semi-connection request message are invalid, and then performing step 205; Step 205, the access terminal will not carry the semi-connection time parameter The semi-connection request message is sent to the access network, and then step 206 is performed. Step 206: The access network receives the semi-connection request message sent by the access terminal, and in response to the semi-connection request message, sends a semi-connection response message to the access terminal, and agrees or denies the access terminal to enter the semi-connected state. In this step, the access network can learn the semi-connection time parameter carried in the semi-connection request message by the access terminal according to the state of the first switch field set in the semi-connection request message, that is, the current status of the access terminal. The case of the requested semi-join time parameter.

In the first embodiment, the first switch field is lbit, and it can be set to two states: state "0" and state "1". In the first embodiment, the two states are respectively used to indicate that the semi-join time parameter fields set in the semi-join request message are all invalid and all valid, that is, three semi-connected time parameter fields semi-connected period SemiConnectedPeriod, semi-connected offset SemiConnectedOffset and semi-connected wakeup durations SemiConnectedWakeDuration are all invalid and all valid. When the first switch field is set to indicate that the semi-connection time parameter field set in the semi-connection request message is all valid, the access terminal will carry all the semi-connection time parameters in the semi-connection request message sent to the access network. . When the first switch field is set to indicate that the semi-connection time parameter field set in the semi-connection request message is all invalid, the access terminal will not carry the semi-connection time parameter in the semi-connected message transmitted to the access network.

In the first embodiment, the correspondence between the specific state in which the first switch field is located and the validity of the semi-join time parameter field set in the semi-join request message, that is, the specific state and half of the first switch field The correspondence between the carrying conditions of the connection time parameters may be pre-configured in the access terminal and/or the access network. The access terminal may set the first switch field to a corresponding state according to the correspondence to implement sending all semi-connection time parameters or not transmitting semi-connection time parameters. After the AT determines whether to send the semi-connection time parameter to the AN, the AT may indicate that the AT carries all the semi-connection time parameters or does not carry in the semi-connection request message sent to the AN by setting the first switch field to the corresponding state. Semi-join time parameter. and After receiving the semi-connection request message after adding the first switch field, the AN can determine the semi-connection time parameter carried by the AT according to the state of the first switch field: It carries all the semi-connection time parameters. Still did not carry the time parameter.

The length of the semi-connection request message is 7 Bytes before the first switch field is added for control. After the first switch field is added in the embodiment 1 of the present invention, if the AT carries all the semi-connection time parameters, the semi-connection request The length of the message is 7 Bytes. If the AT does not carry the semi-join time parameter, the length of the semi-join request message is 5 Bytes, see Table 4. Therefore, the message length is not increased after the switch field is added to the semi-join request message, so no additional overhead is incurred.

Table 4 Example 2

Embodiment 2 of the present invention is substantially the same as the method of Embodiment 1, except that in the second embodiment, the first switch field is 3 bits, and it can be set to eight different states: "000", "001", "010", "Oil", "100", "101", "110", "111". Similar to Embodiment 1, two of the eight states can be used to indicate that all three semi-join time parameter fields set in the semi-join request message are all valid and all invalid, and the remaining six states can be used separately. The various cases in which the three semi-join time parameter fields set in the semi-connection request message are valid are partially valid. For example, in the specific implementation of the second embodiment, when the first switch field is set to the state "111", the three time parameter fields are all valid; when the state "000" is taken, the three time parameter fields are all invalid; "001" indicates that only half of the three fields are valid; when "010" is taken, only the semi-join offset is valid; when "011" is taken, only the half-connection wake-up duration is valid; take "100" The time indicates that only the semi-join period and the semi-join offset are valid; taking "101" indicates that only the semi-join period and the half-join wake-up duration are valid; taking "110" indicates that only the semi-join offset and the semi-join wake-up The duration is valid. Obviously, the correspondence between the specific state of the switch field and the validity of the semi-join time parameter field may vary. For example, in another specific implementation of the embodiment, "000" may be used to indicate that the semi-join time parameter field is all valid. Correspondingly, when the first switch field is set to indicate that the semi-connection time parameter field set in the semi-connection request message is all valid or all invalid, the access terminal will carry in the semi-connection request message sent to the access network. All semi-join time parameters or no semi-join time parameters. When the first switch field is set to indicate a partially valid state in the semi-join time parameter field set in the semi-connection request message, the access terminal will only carry the valid part in the semi-connected message sent to the access network. Partial semi-join time parameter corresponding to the semi-join time parameter field. Therefore, by setting the first switch field to the corresponding state, it is possible to carry only the required semi-join time parameter in the semi-connection request message. For example, in this embodiment, if the access terminal determines that only the semi-connection period needs to be sent to the access network, it can set the first switch field to the state "001", if it is determined that only the semi-connection period and the semi-connection are required to be sent. When biased to the access network, it can be set to the status "100".

Similar to Embodiment 1, in the second embodiment, the specific state and the half of the first switch field The correspondence between the carrying conditions of the connection time parameters may be pre-configured in the access terminal and/or the access network. In the second embodiment, by setting the first switch field to a different state, the access terminal can carry only the semi-connection time parameter or the semi-connection time parameter in the semi-connection request message. Partial semi-join time parameter sent. and

5 When the AN receives the semi-connection request message with the first switch field added, according to the first switch

The status of the field determines the semi-connection time parameter carried in the AT: whether it carries all the semi-connection time parameters, or does not carry the semi-connection time parameter, or only carries part of the semi-connection time parameter; For some time parameters, which part of the time parameter is carried. Wherein, of course, the first switch field can also be set to other lengths according to requirements.

10 and the number of its states corresponds to its length.

Table 5 analyzes the length of the message after adding the first switch field in Embodiment 2. As shown in Table 5, after the switch field is added in the second embodiment of the present invention, if the AT does not carry the semi-connection time parameter, the length of the semi-connection request message is 5 Byte, for example, the AT only carries part of the semi-join time parameter. , the length of the semi-join request message is 6 Byte or 7 Byte, such as

15 AT carries all three semi-join time parameters, then the length of the semi-join request message is 8

Byte. Thus, in Embodiment 2 of the present invention, the AT does not increase the message length without carrying or carrying only a part of the semi-connection time parameter, without incurring additional overhead.

In the third embodiment, the AN determines whether it is necessary to send the semi-connection time parameter to the AT before transmitting the semi-connected response message in response to the semi-connection request sent by the AT; if 5 is, the semi-connection time that the AN will need to transmit The parameter is carried in the semi-connection response message.

The message is sent to the access terminal. Otherwise, the AN sends a semi-connected response message that does not carry the semi-connection time parameter to the access terminal. Thus, when the AN determines that the semi-join time parameter of the AT request is unreasonable, the AN can use its determined time parameter to cover the semi-join time parameter of the AT request.

10 In the specific implementation of Embodiment 3, the prior art semi-connected response message structure (see

See Table 2) to add a second switch field and one or more semi-join time parameter fields. The semi-join response message after adding the second switch field and the three semi-join time parameter fields is shown in Table 6. Field name Length ( bits ) Description

The second switch field can be set to a different state, and different states thereof are used to indicate different situations in which the access network carries the semi-connection time parameter in the semi-connection response message.

3 is a basic flow chart of Embodiment 3 of a method for an access terminal of the present invention to request to enter a semi-connected state. Referring to Figure 3, the method includes the following steps:

Step 301: The access terminal sends a semi-connection request message to the access network to request to enter a semi-connected state.

Step 302: The access network receives the semi-connection request message, and determines whether a semi-connection time parameter needs to be sent to the access terminal; if yes, step 303 is performed; otherwise, step 305 is performed.

As a specific implementation manner of this step, the method may be, but is not limited to, determining that the time parameter needs to be sent to the AT when the AN determines that the time parameter of the AT request is unreasonable.

Step 303: The access network sets the second switch field according to the semi-connection time parameter that needs to be sent, and sets the second switch field to be valid in the semi-connection response message, and the semi-connection time parameter field corresponding to the semi-connection time parameter to be sent is valid. And the semi-join time parameter field corresponding to other semi-join time parameters that do not need to be sent is invalid, and then step 304 is performed.

Step 304: The access network sends a semi-connected response message carrying the semi-connection time parameter to be sent to the access terminal, and then ends the process.

Step 305, the access network sets the second switch field to: indicating that the semi-connection time parameter field set in the semi-connection response message is all invalid, and then step 306 is performed; Step 306: The access network sends a semi-connection response message that does not carry a semi-connection time parameter to the access terminal.

After the step, when the access terminal receives the semi-connection response message, it can learn the semi-connection time carried by the access network in the semi-connection response message according to the state of the second switch field set in the semi-connection response message. The case of the parameter.

Similar to the first switch field in the first embodiment, in the third embodiment, the length of the second switch field is lbit, which can be set to two states. In the third embodiment, the two states are respectively used to indicate that the semi-join time parameter fields set in the semi-connection response message are all invalid and all valid, that is, three semi-connected time parameter fields semi-connected period SemiConnectedPeriod, semi-connected offset The SemiConnectedOff set and the semi-connected wakeup duration SemiConnectedWakeDuration are all invalid and all valid. When the second switch field is set to indicate that the semi-connection time parameter field set in the semi-connection response message is all valid, the access network will carry all the semi-connection time parameters in the semi-connection response message sent to the access terminal. . When the second switch field is set to indicate that the semi-connection time parameter field set in the semi-connection response message is all invalid, the access network will not carry the semi-connection time parameter in the semi-connection response message sent to the access terminal. In the third embodiment, the correspondence between the specific state of the second switch field and the carrying condition of the semi-connection time parameter may be pre-configured in the access terminal and/or the access network. After the AN determines whether to send the semi-connection time parameter to the AT, the AT may indicate that the AN carries all the semi-connection time parameters or does not carry in the semi-connection response message sent to the AT by setting the second switch field to the corresponding state. Semi-join time parameter. When the AT receives the semi-connection response message after adding the second switch field and the time parameter field, the AT can determine the semi-connection time parameter carried in the AN according to the state of the second switch field: The semi-join time parameter still does not carry the semi-join time parameter. In a specific implementation, the AN can determine whether the semi-join time parameter of the AT request is reasonable and determine a reasonable time parameter by using various existing methods. The specific decision method and the determining method are not within the scope of the present invention. Illustratively, when the AN determines that the semi-join time parameter requested by the access terminal is the same as or close to the semi-connection time parameter of the access terminal that has entered the semi-connected state, the access terminal that requests the request to enter the semi-connected state may be determined. The requested time parameter is unreasonable. At this time, the AN can determine that the time parameter that is different or not close to the semi-join time parameter adopted by the access terminal that has entered the semi-connected state is a reasonable semi-join time parameter.

A better effect is that the AT can determine whether a semi-connection time parameter needs to be sent before sending the semi-connection request to the AN, and the AN can determine whether a semi-connection needs to be sent before sending the semi-connection response message in response to the semi-connection request sent by the AT. Time parameter to AT. Specifically, the AT may implement, by using the first switch field set in the semi-connection request message, all half-connection time parameters or partial semi-connection time parameters or no time parameters in the sent semi-connection request message; The second switch field and the semi-join time parameter field set in the connection response message are used to carry all semi-connection time parameters or partial semi-connection time parameters or no time parameters in the sent semi-connection response message.

Example 4

In the fourth embodiment, the second switch field is 3 bits, and can be set to eight different states. The eight different states are respectively used to indicate that the semi-join time parameter fields set in the semi-connection response message are all invalid and all valid. And some of the various situations that are effective. The specific setting example of the second switch field is similar to the first switch field in Embodiment 2, and details are not described herein again. In the fourth embodiment, the AT can set the second switch field to the corresponding state by The semi-connected time parameter carried by the AN in the semi-connected response message sent to the AT does not carry the semi-connected time parameter or only carries the partial semi-connected time parameter that needs to be carried. When the AT receives the semi-connection response message after adding the second switch field and the time parameter field, the AT can determine the semi-connection time parameter carried in the AN according to the state of the second switch field: The semi-join time parameter still does not carry the semi-join time parameter, or only carries part of the semi-join time parameter; if carrying part of the time parameter, which part of the time parameter is carried. Of course, the first switch field may be set to other lengths as needed, and the number of states corresponds to its length.

Similar to the embodiment 3, the embodiment 4 can be implemented in combination with the embodiment 1 or the embodiment 2 to obtain a better effect, and the implementation method is the same as that described above, and will not be described again.

Example 5

Fig. 4 shows a flow chart of the fifth embodiment. As shown in FIG. 4, the method for the access terminal of the embodiment 5 to request to enter the semi-connected state includes:

Step 401: The access terminal sends a semi-connection request message that does not carry a semi-connection time parameter to the access network.

Step 402: The access network receives the semi-connection request message, and determines the value of all semi-connection time parameters required for the access terminal to enter the semi-connected state, and sends a semi-connection response message carrying the all-half connection time parameter to the access terminal. Access terminal.

In the specific implementation of this step, the AN can determine the semi-join time parameter of the AT requesting to enter the semi-connected state by using various existing methods, and the specific determining method is not within the protection scope of the present invention. An example of the AN determining the value of the semi-join time parameter is exemplarily given below. In the actual business, one AN may reside below multiple semi-connected AT, if some ATs enter the semi-connected state when the AT requests to enter the semi-connected state, the AN can determine the AT entering the semi-connected state according to the semi-connected time parameters of the ATs that have entered the semi-connected state. The semi-join time parameter, in particular, the AN may select any parameter value that does not cause the AT to overlap with the wake-up time of the AT of the other semi-connected state.

In the fifth embodiment, the semi-connection request message sent by the AT does not include any semi-connection time parameter field, and only indicates the AT's request for the semi-join. Corresponding to the semi-connection request message, all semi-connection time parameter fields are added to the semi-connection response message sent by the AN, and the AN determines the value of all the semi-connection time parameters, and then sends a semi-connection response message to the AT. The increased semi-join time parameter is carried in, and the AT accepts the time parameter sent by the AN.

The structure of the semi-join request message and the structure of the semi-join response message of the fifth embodiment are shown in Table 7 and Table 8, respectively.

Fig. 5 shows a flow chart of the sixth embodiment. As shown in FIG. 5, the method for the access terminal of the embodiment 6 to enter the semi-connected state includes:

Step 501: The access terminal sends a semi-connection request message carrying only a part of the semi-connection time parameter to the access network.

Step 502: The access network receives the semi-connection request message, and determines a part of the semi-connection time parameter required by the access terminal to enter the semi-connected state, except for a part of the semi-connection time parameter carried in the received semi-connection request message. The value of the semi-join time parameter of the other part is carried, and the all-half connection time parameter is carried in the semi-connection response message and sent to the access terminal.

The structure of the semi-join request message and the structure of the semi-join response message of this embodiment are shown in Table 9 and Table 8, respectively.

Table 9 In the sixth embodiment, the semi-connection request message sent by the AT includes only a part of the semi-connection time parameter field, and the semi-connection request message sent by the AT only carries the semi-connection time parameter corresponding to the part of the time field. After receiving the semi-join request message, the AN determines the values of other semi-join time parameters that are not carried in the semi-join request message, and determines the other semi-join parameters that are determined by the received half of the semi-connection parameters. The connection time parameter is carried in the semi-connection response message and sent to the access terminal. For example, when the AT requests to enter the semi-connected state, only the semi-connected period parameter is sent, and corresponding to the semi-join request, the AN determines the value of the semi-join bias and the semi-join wake-up duration, and is half The connection response message carries the semi-connection bias and the semi-connection wake-up duration and the semi-connection period sent by the AT to the access terminal. The AN carries all of the semi-join time parameters by adding all semi-join time parameter fields in the semi-connection reply message. In this way, the AN can both take into account the AT's expectation of the semi-join cycle, and allow the AN to conveniently arrange the ATs that enter each semi-connected state to evenly waking up at the appropriate time, facilitating the AN to control the forward scheduling and reverse access loads. balanced.

Example 7

Fig. 6 shows a flow chart of this embodiment. As shown in FIG. 6, the method for the access terminal in this embodiment to request to enter the semi-connected state includes:

Step 601: The access terminal sends a semi-connection request message carrying only a part of the semi-connection time parameter to the access network.

Step 602: The access network receives the semi-join time parameter, and determines a part of the semi-join time parameter that is included in the received semi-join request message, among all semi-connection time parameters required for the access terminal to enter the semi-connected state. The value of the semi-join time parameter of the other part is carried, and only the semi-join time parameter of other parts determined by it is carried in the semi-connection response message and sent to the access terminal.

In the seventh embodiment, similar to the sixth embodiment, the semi-connection request sent by the AT The message only carries part of the semi-join time parameter. Different from the sixth embodiment, in the seventh embodiment, only the semi-connection time parameter requested by the AT through the semi-connection request message is added to the semi-connection response message sent by the AN (that is, the AT is carried in the half. The other semi-join time parameter field of the connection request message, except for the semi-connection time parameter in the connection request message, the AN only sends the semi-join time of all semi-connection time parameters required by the AT to enter the semi-connection state except the semi-connection time parameter sent by the AT. The parameter is given to the AT, that is, the AN does not send the semi-connected time parameter requested by the AT.

Example 8

In the eighth embodiment, similar to the seventh embodiment, the semi-connection request message sent by the AT carries only a part of the semi-join time parameter. Different from the embodiment 7, in the eighth embodiment, the semi-connection response message sent by the AN not only adds the semi-connection time parameter field, but also adds whether to indicate whether the AT has been requested in the semi-connection response message. The switch field (ie, the third switch field) of "half the connection time parameter is the same as the requested time parameter" of the semi-connection time parameter (ie, the semi-connection time parameter carried by the AT in the semi-connection request message). When the AN considers that the parameter requested by the AT is reasonable, it sets the switch to the open state. At this time, the AN does not need to send the semi-connection time parameter that the AT has requested; when the AN considers that the time parameter of the AT request is unreasonable, it will The switch is set to the closed state. At this time, the AN determines the value of the semi-connection time parameter that the AT has requested, and carries the semi-connection time parameter that the AT has requested in the semi-connection response message. That is, in this embodiment, in addition to determining and carrying the semi-join time parameter that the AT has not requested, the AN needs to determine and carry the unreasonable time parameter when the time parameter of the AT request is unreasonable.

Fig. 7 shows a flow chart of the eighth embodiment. As shown in FIG. 7, the method for the access terminal of the embodiment to enter the semi-connected state includes:

Step 701: The access terminal sends a semi-connection request message carrying only a part of the semi-connection time parameter to the access network. Step 702: The access network receives the semi-connection request message, and determines whether the partial semi-connection time parameter carried in the received semi-connection request message is reasonable, that is, whether the semi-connection time parameter requested by the AT is reasonable, and if yes, performing the step 703, otherwise step 704 is performed; Step 703, the access network sets a field of "SeminConnectedPeriodSameAsRequestMessage"("A field with the same time parameter of the request", a third switch field) to an open state, and determines all the semi-connection time parameters The value of the semi-join time parameter of the other part except the semi-connection time parameter requested by the AT (that is, the partial semi-connection time parameter carried in the semi-connection request message); then step 705 is performed;

Step 704: The third switch field of the access network is set to a closed state, and determining a value of a semi-connection time parameter of the other part except the semi-connection time parameter requested by the AT, and determining the AT request The value of the unreasonable semi-join time parameter;

Step 705: The access network carries the determined semi-connection time parameter in the semi-connection response message, and sends the message to the access terminal.

After the step, when the access terminal receives the semi-connection response message, it can learn the semi-connection time parameter specifically carried by the access network according to the state of the third switch field.

In the eighth embodiment, the open state of the third switch field corresponds to a reasonable time parameter of the AT request, in which the AN does not carry the time parameter of the AT request; the closed state of the third switch field corresponds to the AT request The time parameter is unreasonable. In this state, the AN carries the time parameter of the AT request. In a specific implementation, the correspondence between the state of the third switch field and the reasonableness of the time parameter of the AT request may be preset in the access terminal and/or the access network. For example, if the third switch field is set to "1", it is open, and the time parameter corresponding to the AT request is reasonable; when "0" is taken, the corresponding closed state, the time parameter corresponding to the AT request is unreasonable.

In addition, in the eighth embodiment, the number of switch fields may be increased in the semi-connection response message sent by the AN, corresponding to the number of time parameters carried in the AT request message. Lift For example, if the AT carries two time parameters in the semi-connection request message of the AT, correspondingly, in the response message of the AN, two switch fields may be added to respectively correspond to the two time parameters carried by the AT. . If one of the two time parameters is reasonable and unreasonable, the states of the two switch fields are different, and the AN only determines the time parameter that is unreasonable and carries it in the semi-connection response message.

Illustratively, in the eighth embodiment, the semi-join time parameter requested by the AT through the semi-join request message is a semi-connection period. The structure of the semi-join request message and the structure of the semi-join response message of the eighth embodiment are shown in Table 9 and Table 10, respectively. As shown in Table 10, when the AN accepts the semi-connection period sent by the AT, the AT does not carry the parameter in the semi-connection response message, and the length of the field of the semi-connection period time parameter in the semi-connection answer message is Obit; When the semi-connection period sent by the AT is not accepted, the time parameter may be carried in the semi-connection response message, and the time parameter field in the semi-connection response message is 8 bits.

Table 10 has the common feature of the foregoing embodiments 5, 6, 7, and 8 that the access terminal does not carry all the half connections. And connecting, by the access network, a semi-connection request message to the access network; and determining, by the access network, the other semi-connection time parameter except the semi-connection time parameter carried in the semi-connection request message And transmitting, by the one or more semi-join time parameter fields set in the semi-connection response message, the value of the determined other semi-connection time parameter in the semi-connection response message to the access terminal. Therefore, when the AT sends a request to enter the semi-connected state to the AN, the AT may not carry any semi-join time parameter or only part of the semi-join time parameter, and the AN determines all or part of the semi-join time when the AT enters the semi-connected state. The parameter is sent to the AT through a semi-connected response message, and the AT accepts the time parameter sent by the AN.
