Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of system of selection and transmission method of base station type information of base station.
Background technology
Along with the continuous development of the communication technology, Femtocell (indoor base station) and RS novel base stations such as (RelayStation, trunk desks) has appearred.
Femtocell is a kind of microminiature base station equipment, is mainly used in family and the office environment.What Femtocell mainly solved is that indoor signal covers incomplete problem, improves indoor signal coverage varies by the method in a small-power base station of indoor installation, strengthens indoor communication capacity.
From realizing that Femtocell and ordinary base station do not have the difference of essence, just the power ratio ordinary base station is little a lot, and its coverage is usually in tens meters.It also is helpful that Femtocell covers for the signal that improves the sparse areas of population such as suburb.
Simultaneously, use, so AT (terminal) must carry out authentication when inserting Femtocell,, stop the disabled user to insert to guarantee that validated user can correctly insert because Femtocell generally only offers groups of people.
RS and Femtocell are similar, and its difference is: 1, RS is bigger slightly than the coverage of Femtocell; 2, wireless mode is adopted in the backhaul of RS (backhaul); 3, RS supports multi-hop (multi-hop) structure, comprises single-hop Relay base station and multi-hop Relay base station.
Because terminal is in the wireless environment of a complexity, may receives a plurality of signal of base station simultaneously and between different base station, switch.In the present base station handover mechanism, whether terminal determines base station shifting according to the pilot strength information that detects the base station, in communication system, introduce multiple base station type after, the factor that influence quality of service after terminal handover success rate and the switching increases.
For example, after Femtocell introduced wireless communication system, because Femtocell has private ownership, it provides service to a few peoples, have only user could insert Femtocell by authentication, but not Femtocell user is when handoff sectors, also can constantly attempt inserting Femtocell, because non-Femtocell can't pass through authentication, finally must be rejected service, and it constantly attempts inserting the process of Femtocell, not only can waste the access-in resource of Femtocell, and increased himself power loss, even may cause the service of can not get for a long time.And, may exist a large amount of non-Femtocell users in the system, its quantity even can be more than Femtocell user is if the non-Femtocell of so big quantity will cause a large amount of wastings of resources with attempting inserting Femtocell per family.
The introducing of RS can produce some system problems equally, has clearly proposed the notion of structure Wireless MESH (netted) network in the 802.16J agreement, in the technical plan of super mobile broadband (UMB) system, has also proposed the demand of Wireless MESH network.In the MESH network, need to introduce the above RS of two-stage, one-level RS can't make up Wireless MESH network, because the introducing of RS makes the storage repeating process that has data in the system, every introducing one-level RS, whole time delay that will corresponding increase data.With the UMB system is example, supposes that it is 2 that RS successfully receives the average HARQ of a secondary data (mix automatically and retransmit) number of times, introduces the time delay of 8-11ms for the then big appointment of transmission of data.For the VOIP business, the time delay of eating dishes without rice or wine of its maximum is about 20ms, and therefore, the VOIP business can only be born the route time delay of one-level RS at most, if the link between terminal and the base station surpasses one-level RS, the QOS of VOIP business (service quality) then possibly can't ensure.
