Description
Technical Field
The method relates to the field of communication, in particular to a network access method and a network access system.
Background
In a wireless communication system, radio coverage is provided over a certain geographical range by a Base Station (BS) using a designated radio channel. To extend coverage or to extend capacity, one or more relay stations may be placed between the mobile terminal and the base station, which for the mobile terminal is equivalent to a base station.
The base station/relay station, which is a control station of the wireless communication system, may be classified into an advanced control station and a legacy control station according to a communication protocol supported. The Advanced control Station refers to a Base Station/Relay Station (ABS/ARS) supporting an Advanced communication protocol, and the legacy control Station refers to a Base Station/Relay Station (YBS/YRS) supporting a legacy communication protocol. In the technique considering compatibility, for the advanced control station, its frame is divided into a first area and a second area. The first region may support only advanced communication protocols and may therefore also be referred to as an advanced region, and the second region may support legacy communication protocols and may therefore also be referred to as a legacy region. Similarly, for mobile terminals, it is also possible to divide into advanced mobile terminals and legacy mobile terminals, the advanced mobile terminals can operate in the first area or the second area, and the legacy mobile terminals can operate only in the second area. For a legacy mobile terminal, the second area of the advanced control station corresponds to a legacy control station. And for the advanced mobile station, when the advanced mobile station accesses the conventional control station, for the conventional control station, the advanced mobile station is a conventional mobile terminal.
In addition, the advanced control station may support only the advanced communication protocol, and in this case, the advanced control station may have only the first area.
The following is further described by taking the IEEE802.16 standard as an example. The IEEE802.16 standard is an advanced air interface standard proposed for the microwave band, which sets out specifications of a physical layer (PHY) and a Media Access Control (MAC) layer. The IEEE802.16m including the relay structure is the most advanced standard technology in the current IEEE802.16 standard, and the IEEE802.16m (hereinafter, referred to as 16m) is based on the traditional standards such as the IEEE802.16e (hereinafter, referred to as 16e) and the IEEE802.16j (hereinafter, referred to as 16 j).
Based on the above description, the advanced control station (base station/relay station supporting the 16m protocol) can be compatible with the legacy mobile terminal (mobile terminal supporting the 16e protocol), and likewise, the advanced mobile terminal (mobile terminal supporting the 16m protocol) should be able to access the legacy control station (base station supporting the 16e or relay station supporting the 16 j). The first Zone (also called advanced Zone, 16m Zone, abbreviated as MZone) supports the advanced communication protocol defined by 16m, and the second Zone (also called Legacy Zone, abbreviated as LZone) can support the protocol of 16e/16 j. Furthermore, the advanced control station may also only have MZone.
Generally, when a control station in the system evolves from a legacy control station to an advanced control station, a network (also referred to as an access service network, ASN) to which the control station is connected also evolves from the legacy network to the advanced network accordingly. However, in an actual system, since the development speeds of the control station and the network are not necessarily synchronized, or the market development requires the use of advanced technology as soon as possible, there occurs a case where the control station is an advanced control station and the access service network is a conventional network. At this time, if the advanced communication protocol is directly used in the air interface of the advanced mobile terminal and the advanced control station without any change, a problem occurs in the subsequent communication process between the advanced control station and the conventional network.
For example, when a mobile terminal accesses a network, the mobile terminal usually finds a control station and then implements downlink synchronization according to a synchronization signal of the control station. And during uplink synchronization, the mobile terminal sends a ranging code to the control station after acquiring uplink parameters from the broadcast message, and the control station sends a ranging feedback message to the terminal after receiving the ranging code. And according to the feedback message, the terminal sends a ranging code or a ranging message to realize uplink synchronization with the control station and continues to perform a series of subsequent processes, thereby completing the initial access of the network. Still taking the 16m standard as an example, when the 16m mobile terminal accesses the network, it needs to send a special identifier (identifier AMSID for protecting terminal privacy) calculated by using the terminal MAC address to the control station, and the control station will transmit the special identifier to the access service network for subsequent encryption, but the traditional access service network cannot recognize the special identifier, so the 16m mobile terminal cannot send the special identifier under the control station supporting the traditional access service network. Similar problems exist with the many different types of services provided by access service networks, and the inability of conventional access service networks to support advanced air interface communication protocols has become a bottleneck limiting the development of communication networks.

Detailed Description
The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
It should be noted that, in this section, the advanced mobile terminals all refer to mobile terminals supporting the advanced communication protocol, the advanced control stations all refer to control stations supporting the advanced communication protocol, and include base stations and relay stations, where the base stations include macro base stations, micro base stations, and pico base stations, and the access service networks all refer to traditional access service networks supporting the traditional communication protocol and providing the traditional access service.
Referring to fig. 1, a flowchart illustrating a first step of a network access method according to a first embodiment of the present invention is shown, which may specifically include the following steps:
step 101: the advanced mobile terminal is accessed to an advanced control station connected to a traditional access service network;
step 103: in the access process, the advanced mobile terminal sends a negotiation message to the advanced control station;
the negotiation message may be a MAC layer message and/or a higher layer message, and the negotiation message includes configuration information of a conventional communication protocol.
Step 105: the advanced control station transmits a response message of the negotiation message to the advanced mobile terminal.
The response message includes configuration information for a legacy communication protocol.
By the embodiment, the advanced control station and the advanced mobile terminal can find the communication capability suitable for accessing the traditional access service network through negotiation, so that the problem that the traditional access service network cannot support the advanced air interface communication protocol is effectively avoided.
Referring to fig. 2, a flowchart of the steps of a second embodiment of the network access method of the present invention is shown. The embodiment is suitable for an advanced control station including a first area and a second area, and is also suitable for an advanced control station including only the first area, and specifically may include the following steps:
step 201: the advanced mobile terminal starts to access an advanced control station in a first area and sends a terminal identifier which can be identified by a traditional access service network;
step 203: the advanced mobile terminal and the advanced control station negotiate a configuration that can be supported by accessing the legacy access service network during a subsequent access procedure.
The advanced control station may be a base station or a relay station, and the base station may be a macro base station, a micro base station, or a pico base station. In this embodiment, the base station is used as an advanced control station.
Specifically, the advanced control station transmits information supporting the legacy access service network in the first area. The information is used to instruct the advanced mobile terminal to not send an identifier (e.g., locally computed AMSID) that cannot be identified by the legacy access service network when accessing, but to send an identifier (e.g., the device's MAC address, alternatively referred to as MAC ID) that can be identified by the legacy access service network.
The advanced control station may transmit the information supporting the legacy access service network in a broadcast or multicast manner, and the information may be included in system broadcast information or multicast information. The information supporting the legacy access service network may be a specific MAC version or a dedicated indication bit. Taking the 16m system as an example, the broadcast information of the 16m system may be a super frame header SFH (super frame header), and the information supporting the conventional access service network occupies 1 bit of the SFH. When the bit is 0, the advanced control station supports the traditional access service network, when the bit is 1, the advanced control station does not support the traditional access service network, or vice versa, when the bit is 1, the advanced control station supports the traditional access service network, and when the bit is 0, the advanced control station does not support the traditional access service network. The information may be used only to instruct the advanced mobile terminal to transmit an identifier recognizable by the legacy access service network upon access, or may be used to instruct the advanced mobile terminal to operate under the advanced control station using legacy communication configuration parameters.
The advanced mobile terminal receives the information supporting the traditional access service network, and sends an identifier (such as a media access control address, MAC address, or MAC ID, of the device, which is a globally unique 48-bit address and can be known by the terminal when the device is manufactured) that can be identified by the traditional access service network during the access process. The identification may be included in the ranging request message (AAI _ RNG-REQ) or may be included in a higher layer message.
The advanced control station enables the advanced mobile terminal to directly know that the advanced control station supports the traditional access service network by sending the information supporting the traditional access service network, thereby saving the information interaction flow and reducing the signaling overhead.
Optionally, the advanced mobile terminal may send information supporting the legacy access service network during an access procedure, and the target information may be included in a ranging request message (AAI _ RNG-REQ) or may be included in a higher layer message. May be 1 bit. When the bit is 0, the advanced mobile terminal supports the conventional access service network, when the bit is 1, the advanced mobile terminal does not support the conventional access service network, or vice versa, when the bit is 1, the advanced mobile terminal supports the conventional access service network, and when the bit is 0, the advanced mobile terminal does not support the conventional access service network. The advanced mobile terminal sends the information supporting the traditional access service network, so that the advanced control station can easily know that the advanced mobile terminal supports the traditional access service network, the information interaction flow is saved, and the signaling overhead is reduced.
The advanced mobile terminal and the advanced control station negotiate the configuration which can be supported by accessing the conventional access service network through a negotiation message containing configuration information in a subsequent access process. The negotiation message can be sent by the advanced mobile terminal, and the advanced control station responds and sends a response message; or may be sent by the advanced control station, the advanced mobile terminal responding and sending a response message. The negotiation message and the response message may be MAC layer messages (e.g., capability negotiation messages or ranging messages) and/or higher layer messages. Configuration information is set by using the reserved area of the MAC layer message and the high layer message, and the air interface configuration negotiation of the traditional access service network can be realized without greatly changing software and hardware, so that the realization cost is saved.
When the negotiation message sent by the advanced mobile terminal is the capability negotiation message, referring to fig. 3, the advanced mobile terminal sends the capability negotiation request message to carry the configuration information supported by the advanced mobile terminal, and correspondingly, the advanced control station sends the capability negotiation response message to carry the configuration information supported by the advanced control station.
The configuration information may be a specific configuration parameter or a configuration index, and different configuration indexes correspond to different configuration parameters or configuration parameter combinations. The configuration parameters are directly used, so that the advanced control station can quickly acquire the configuration parameter information of the traditional access service network; using the configuration index, space may be reserved for subsequent configuration information.
The configuration parameter information may indicate that the advanced mobile terminal and the advanced control station are or are not in a certain configuration (e.g., in a power saving mode, no deregistration mode is supported, idle mode and sleep mode are supported), and/or how the relevant configuration parameters are set when the advanced mobile terminal and the advanced control station are in a certain configuration. (e.g., in idle mode, advanced mobile terminals entering idle mode are identified using methods in legacy idle mode. thus, advanced mobile terminals in idle mode may be recognized by the legacy access service network while moving between different advanced control stations.)
The configuration parameters are configuration parameters of a traditional access service network, and include one of the following or any combination thereof: data transmission parameters, scheduling parameters, power saving mode parameters, scanning process parameters, handover process parameters, network entry process parameters, ranging process parameters, and security parameters. By using the parameters, the advanced control station can conveniently and quickly acquire the configuration condition of the traditional access service network.
Wherein the data transmission parameters further comprise ARQ (automatic repeat request) parameters and/or HARQ (hybrid automatic repeat request) parameters; the scheduling parameter at least comprises one of the following or any combination thereof: service flow parameters, quality of service parameters (QoS), bandwidth allocation parameters; the power saving mode parameter at least comprises one of the following parameters or any combination of the following parameters: a sleep mode parameter, an idle mode parameter, a deregistration mode parameter; the safety parameters at least comprise one of the following or any combination of the following: authentication parameters, data encryption and/or decryption parameters.
When the negotiation message sent by the advanced mobile terminal is a higher layer message, as shown in fig. 4, the advanced mobile terminal and the advanced control station negotiate the configuration that can be supported by the access legacy access service network through a higher layer message (e.g., AAI _ L2-XFER message or AAI-SCD message and feedback message or other messages) in the subsequent access procedure, and the higher layer message containing the configuration information is included in the upper layer protocol and interacts between the advanced mobile terminal and the advanced control station. The sequence of the high-level message interaction can be initiated by the advanced mobile terminal and responded by the advanced control station; or the advanced control station can initiate and respond by the terminal.
It should be noted that fig. 3 and 4 have replaced the advanced control station with a base station, but those skilled in the art should understand that the advanced control station may be a macro base station, a micro base station, a pico base station, a relay station, etc.
Referring to fig. 5, a flowchart of steps of a third embodiment of a network access method according to the present invention is shown, where the present embodiment is applicable to an advanced control station including a first area and a second area, and specifically may include the following steps:
step 501: the advanced mobile terminal starts to access the advanced control station in the second area;
step 503: the advanced mobile terminal and the advanced control station negotiate a configuration that the legacy access service network can support in the second area in a zone switching process in which the advanced mobile terminal switches from the second area to the first area;
step 505: the advanced mobile terminal transitions to the first zone.
Specifically, the advanced mobile station accesses the advanced control station in the second area, and the advanced mobile station may send information including information supporting a legacy access service network during the access process, where the information may be included in a reserved word of the ranging request message and occupy 1 bit. When the bit is 0, the advanced mobile terminal supports the conventional access service network, when the bit is 1, the advanced mobile terminal does not support the conventional access service network, or vice versa, when the bit is 1, the advanced mobile terminal supports the conventional access service network, and when the bit is 0, the advanced mobile terminal does not support the conventional access service network.
The second area is an area supporting the traditional communication protocol, and the advanced mobile terminal accesses the advanced control station through the area, so that the condition that the advanced mobile terminal cannot access the advanced control station because the traditional access service network does not support the advanced communication protocol is effectively avoided.
The advanced mobile terminal may perform an access procedure for the second area and then switch to the first area, or may switch to the first area during the access procedure for the second area. The zone switch may be actively initiated by the advanced mobile terminal in the second zone or by the advanced control station in the second zone.
The advanced mobile terminal and the advanced control station negotiate the configuration that can be supported by the access legacy access service network through a negotiation message containing configuration parameters during the zone switch process, and the negotiation message may be a signaling message for zone switch, such as a ranging response message. And the negotiation in the area switching process accelerates the access speed of the advanced mobile terminal to the advanced control station.
When the advanced mobile terminal actively initiates the zone switch, as shown in fig. 6, the zone switch request message sent by the advanced mobile terminal in the second zone may include information supporting the legacy access service network and/or configuration information of the advanced mobile terminal (for example, if the advanced mobile terminal already sends information supporting the legacy access service network when the network enters, it may only send the configuration information without sending this information again). The advanced control station receives the area switch request message sent by the advanced mobile terminal, and sends a response message (or called command message) in the second area, wherein the response message can also comprise information supporting the traditional access service network and/or comprise corresponding configuration information of the advanced control station.
When the advanced control station actively initiates the zone switch, as shown in fig. 7, the zone switch command message transmitted by the advanced control station in the second zone may include information supporting the legacy access service network and/or include corresponding configuration information of the advanced control station. After receiving the zone switch command message, the advanced mobile station sends a ranging request message in the first zone, where the ranging request message may also include information supporting a conventional access service network and/or include corresponding configuration information of the terminal.
The advanced mobile terminal completes the remaining network access procedure in the first area according to the received area switch command message.
The configuration information in this embodiment may refer to embodiment two shown in fig. 2, and is not described here again.
It should be noted that fig. 6 and 7 have replaced the advanced control station with a base station, but those skilled in the art should understand that the advanced control station may be a macro base station, a micro base station, a pico base station, a relay station, etc.
Referring to fig. 8, a flowchart of a fourth step of an embodiment of a network access method of the present invention is shown, where the embodiment is applicable to an advanced control station including a first area and a second area, and specifically may include the following steps:
step 801: the advanced mobile terminal starts to access the advanced control station in the second area;
step 803: the advanced mobile terminal is switched from the second area to the first area of the advanced control station;
step 805: after the advanced mobile terminal is transferred to the first area, a configuration that can be supported by the legacy access service network is negotiated with the advanced control station in the first area.
Specifically, the advanced mobile terminal accesses the advanced control station in the second area, and the advanced mobile terminal may transmit information including information supporting a legacy access service network during an access procedure, which may be included in the ranging request message.
The advanced mobile terminal may perform an access procedure for the second area and then switch to the first area, or may switch to the first area during the access procedure for the second area. The zone switch may be actively initiated by the advanced mobile terminal in the second zone or by the advanced control station in the second zone.
When the advanced mobile terminal actively initiates the zone switch, as shown in fig. 9, the zone switch request message transmitted by the advanced mobile terminal in the second zone may include information of the legacy access service network (this case applies to the case where the information of the legacy access service network is not transmitted during the initial access). The advanced control station receives the area switching request message and transmits a response message (or called a command message) in the second area, wherein the response message can also comprise information supporting the traditional access service network.
When the advanced control station actively initiates the zone switch, as shown in fig. 10, the advanced control station sends a zone switch command message in the second zone, which may include information supporting the legacy access service network, and in this case, the ranging request message sent by the advanced mobile station in the first zone may include information supporting the legacy access service network.
After the advanced mobile terminal is switched to the first area, the advanced mobile terminal and the advanced control station negotiate the configuration which can be supported by the access traditional access service network through a negotiation message containing configuration information, wherein the negotiation message can be an MAC layer message and/or a higher layer message. Further, when the negotiation message is a MAC layer message, the message may be a capability negotiation message or a ranging message. The advanced mobile terminal negotiates with the advanced control station after being converted into the first area, and the negotiation stability is improved.
The configuration information in this embodiment may refer to embodiment two shown in fig. 2, and is not described here again.
It should be noted that fig. 9 and 10 have replaced the advanced control station with a base station, but those skilled in the art should understand that the advanced control station may be a macro base station, a micro base station, a pico base station, a relay station, etc.
Referring to fig. 11 and 12, a network access signaling flow diagram of a fifth embodiment of a more optimized network access method based on the fourth embodiment shown in fig. 8 is shown, and this embodiment is applicable to an advanced control station including a first area and a second area. In the fourth difference from the embodiment shown in fig. 8, in the present embodiment, the advanced mobile terminal does not know whether the advanced control station supports the legacy access service network during the access process.
Specifically, the advanced mobile terminal accesses the advanced control station in the second area, and the advanced mobile terminal does not transmit information including support for a legacy access service network during the access.
The advanced mobile terminal may perform an access procedure for the second area and then switch to the first area, or may switch to the first area during the access procedure for the second area. The zone switch may be actively initiated by the advanced mobile terminal in the second zone or by the advanced control station in the second zone.
When the advanced mobile terminal actively initiates the zone switch, as shown in fig. 11, the zone switch request message transmitted by the advanced mobile terminal in the second zone may include information supporting the legacy access service network. The advanced control station receives the area switching request message and sends a response message in the second area.
When the advanced control station actively initiates zone switch, as shown in fig. 12, the advanced control station sends a zone switch command message in the second zone, and the advanced mobile station sends a ranging request message in the first zone.
After the advanced mobile terminal is switched to the first area, the advanced mobile terminal and the advanced control station negotiate the configuration which can be supported by the access traditional access service network through a negotiation message containing configuration information, wherein the negotiation message can be an MAC layer message and/or a higher layer message. Further, when the negotiation message is a MAC layer message, the message may be a capability negotiation message or a ranging message.
In this embodiment, the configuration information may be specific configuration parameter information, or may also be configuration indexes, where different configuration indexes correspond to different configuration parameters or parameter combinations.
The configuration parameter information may indicate how the configuration parameters are set when the advanced mobile terminal and the advanced control station adopt a certain configuration or do not adopt a certain configuration, and/or when the advanced mobile terminal and the advanced control station adopt a certain configuration.
